DESCRIPTION OF THE INVENTION
[0016]
　It will be described with reference to the accompanying drawings embodiments of the present invention.
Example 1
[0017]
　First, keep revealed adoptable herbaceous biomass present invention. They are capable adopted those exemplified in Patent Document 1, specifically is as follows.
[0018]
　These are, for example, Sorahatebo (EFB), pulp fiber, palm of pruned branches, of palm old (trunk), or Farukata shell, bark (bark), Farukata branches pruning, the Farukata old, or eucalyptus, acacia, tung, mangrove bark (bark), wood chips after acquisition core, pruned branches, or banana empty bunch, banana branches pruning, banana leaves, banana old, or pineapple, etc. bamboo. Lignite, peat, it is applicable to those high base ingredients such as sub-bituminous coal. Further water plants such as algae, but vegetables and the like, in the following description explaining an example of bamboo.
[0019]
　Although commonly used shell and the outer shell which remains after taking palm of fact palm oil as biofuel, part of the tuft fruit are rounded melting temperature of the content is high and ash chlorine It is left in which no dumping used as a fuel by a low. Cause melting temperature lower ash is due to the high 20-30% potassium content in the ash.
[0020]
　In addition, such as bamboo, such as a high chlorine content, but you want to use as a renewable fuel, chlorine and sodium, potassium is high, unused biomass can not use a lot. These biomass carbonizing, although attempted to modification by a method such as impurity elution with acid solution, not be modified until (mono-fuel combustion in the combustion state) can state alone use.
[0021]
　Biomass reforming system of the present invention is composed of three processes. In the following description, as an example of using the herbaceous biomass as described above that although the case of bamboo, be other herbaceous biomass as long as it is turned is chipped, the following the three processes are possible adopted without major changes.
[0022]
　The first process is for separating the bamboo dehydration chip and dehydration water "bamboo was atomized, immersed atomized bamboo in water at atmospheric pressure, dried bamboo, the dehydrated water dehydrated chips with separated to obtain the dehydrated water as high potassium solution "it is intended.
[0023]
　The second process relates to dehydrated chip, performs a modification treatment by calcium carbonate as a high melting temperature replacement material as required.
[0024]
　A third process relates to the dehydration water, dehydrated water containing high potassium solution, and a portion of the dehydrated chips dried as fuel, is intended to obtain a solid.
[0025]
　It shows a system diagram according to a first process of the present invention in FIG. Input from outside to the first process PR1 is circulating water W3 bamboo B1 and industrial water W1, the output to the outside from the first process PR1 is the circulating water W3 dehydration water W2 and dehydrated chip B2 .
[0026]
　Among these, it is as follows bamboo B1 will be described a process comprising dehydration chip B2. First, bamboo B1 enters the bamboo chipper 3 bamboo supply feeder 2, is shredded. Bamboo B1 became chipped chopped is stored bamboo chip silo 4. Bamboo chip silo 4 are level meter 5 is installed, it comes to decelerate the speed of bamboo supply feeder 2 above specified level, adjusts the chip amount.
[0027]
　On the other hand, was accumulated in the circulating water tank T1 water is sent to the elution tank 9 via a water supply line L1 by the circulation water pump P1, a jet pulse John pump P2 mounted to the lower portion of the bamboo chips silo 4 to the middle pass. The Saitake chip silo 4 becomes negative, bamboo chips discharged from bamboo chips silo 4 is conveyed to the elution vessel 9 by the water flow.
[0028]
　The in dissolution vessel 9 retention device 10 is installed at the entrance section. Retention device 10 is a device that takes the residence time for the chlorine bamboo B1, potassium contacts eluted with enough water by residence. Solution and bamboo chips exiting the retention device 10 while being agitated by the agitator 11 in the elution vessel 9, settle to the tank bottom by the weight of the bamboo chips. Incidentally, the solution is returned again to the circulating water tank T1 through the common overflow line L2.
[0029]
　Bamboo B1 of sediment at the bottom of the dissolution tank 9 is cut out by a screw feeder 16, sent to the dehydrator 17, a centrifuge capacity, it is dehydrated chips and (dehydrated chip B2) divided into dehydrated water W2.
[0030]
　The above is the process of bamboo B1 is dehydration chip B2. Next, a description will be given industrial water W1 is an input from another external.
[0031]
　In the foregoing description, in order to put the bamboo chips dehydrator 17 is required to some extent in a fluid state, and potassium water bamboo chips B1 had settled have, chlorine concentration higher for a flow the rinse water for performing the rinse needs to be turned on. The rinsing water, the water supplied by the rinse water water amount adjusting valve 18 which also serves as a supply from the industrial water W1, dehydration water W2 flows into the rinsing water tank T2, via the rinsing water circulating valve 21 by rinse water circulation pump P3 is the sum of the water is returned again to the entrance of the dehydrator 17 Te. Thus, industrial water W1 is in the first stage is used as the rinse water. Incidentally, as described later, the process of the water in the first process PR1 forms a essentially closed loop, the external is discharged only as a dehydrating water W2 from the eluate tank T3. Industrial water W1 is in the medium and long term, it is of position as makeup water commensurate with the emissions of the dehydration water W2.
[0032]
　Next, a description will be given dewatering water W2 outputted from the first process PR1 to the outside. As this assumption, about the process of the water in the first process PR1 forms essentially closed loop, which is formed by conventional overflow line L2 and the water supply line L1. In some, a small loop is formed between the rinse water tank T2 and the dehydrator 17, or albeit forming a line by rinsing draining unloading valve 23 during the rinse water tank T2 and the circulating water tank T1, to form a closed-loop basically.
[0033]
　Thus, primary chlorine bamboo B1 guided with the rinse water in the rinse water tank T2 is potassium component would the medium and long term by the circulation in the closed loop will increase the concentration. Circulating water of increased concentration is guided to the eluate tank T3 while monitoring the appropriate concentration. For example, in the middle of the water supply line L1 is installed circulating water potassium meter 12, in the case of circulating water normal concentration or more which passes through transferring to the eluate tank T3 by circulating water sampling valve 13. Incidentally, circulating water extraction valve 13 monitors the level level gauge 54 to the circulating water tank T1 with potassium concentration, equal to or larger than the prescribed value may be one that combines the function of extracting the circulating water so that the specified value . Further, when the water level of the elution vessel 9 rises abnormally in the eluate tank T3, are emergency overflow line L3 so as not to discharge to the outside is installed, guide the circulating water eluate tank T3 from this route is he.
[0034]
　It should be noted that the major functions other than those described above in the first process PR1 is as follows. For example, the rinse water tank T2 is installed level meter 22, and discharged to the circulating water tank T1 if more than the specified level in the rinsing water drain unloading valve 23 is used as circulating water. Further, the circulating water tank water level control valve 25 to inject directly industrial water W1 if decreased level is installed in the circulating water tank T1. Once below the rinse water tank T2 is likewise specified level is rinse water tank water level control valve 24 to inject water directly into the tank from the industrial water.
[0035]
　It shows a system diagram according to a second process of the present invention in FIG. Input from the outside to the second process PR2 includes a dewatering chip B2 from the first process PR1 in FIG. 1, a conveying air A1 from the first process of Figure 3 to be described later, the second process PR2 output from the outside, the reforming fuel B3, B4, a combustion air A2.
[0036]
　Dehydration chip B2 from the dehydrator 17 in the first process PR1 in FIG. 1 is carried into the bamboo dehydration chip silo 26 in the second process PR2, it has been accumulated. Bamboo dehydrated chip silo 26 are level gauge 53 is installed, the amount discharged from bamboo chips silo 4 in the first process PR1 in FIG. 1 in this signal, controls the bamboo chips amount to dehydration by the screw feeder 16 doing. Figure 2 describes only the level meter 53 is omitted and the amount discharged from bamboo chips silo 4 in FIG. 1, the description of the control device for controlling the bamboo chips amount to dehydration by the screw feeder 16 .
[0037]
　The air line LA1 of FIG. 2, are introduced conveying air A1 warmed for shipment bamboo dehydrated chips, dehydrated chips through the bamboo chips table feeder 33 are accumulated in the bamboo dehydration chip silo 26 B2 is sent to the bamboo chip bag filter 29. The air line LA1 is calcium carbonate accumulated in the calcium carbonate silo 34, through the calcium carbonate table feeder 35 installed in the calcium carbonate silo 34 lower, the amount commensurate with the speed of the bamboo chips table feeder 33, turned It is. This dehydration chip B2 in a state in which calcium carbonate is mixed is fed to the bamboo chips bag filter 29 by. Although in the embodiment of FIG. 2 describes describe examples of mixed calcium carbonate, may be other than calcium carbonate if high melting point substance that melts at a basically 1500 ° C. or higher. These are, for example, silica, diatomaceous earth, lime, etc.. Note the case in the high melting point substance, each ultimately in combustion phase oxide CaO or SiO 2 be one that generates a melting point of CaO is 2613 ° C., SiO 2 melting point is at 1650 ± 75 ° C. melts at either 1500 ° C. or higher. Calcium and silica carbonate, diatomaceous earth, lime, etc., a high melting point substance. Will be described later why the incorporation of high melting point materials.
[0038]
　The internal transport air pipe shown air line LA1, dehydration chip B2 calcium carbonate and bamboo contact, calcium carbonate adheres to the bamboo chip surface. Furthermore the conveying air A1 heated by the air heater, is also excluded at the same time the water of dehydration chip B2, is dried. Dehydration chip B2 and calcium carbonate are charged into bamboo chips bag filter 29 in a state of further contacts bamboo chips bag filter 29 on slag cloth, calcium carbonate adheres to the bamboo chip surface. Also part of the calcium carbonate remains on the fabric Ro become coating material filter cloth.
[0039]
　Trapped bamboo chips bag filter 29, bamboo chips calcium carbonate adheres to the surface, it is temporarily stored in the bamboo fuel chip silo 36. The bottom of the bamboo fuel chip silo 36 to the reforming fuel dispensing rotor 38, bamboo fuel chip supply rotor 37 is provided. Among them, the outlet of the reforming fuel dispensing rotor 38, for example pays out reforming fuel B3 as a product due reformate FIBC. Reformed fuel dispensing rotor 38 is a signal of level meter 39, the level is the reformed fuel B3 discharged rotated if the specified value or more, reducing the level of bamboo fuel chip silo 36.
[0040]
　The bamboo fuel chip supply rotor 37, the third process in FIG. 3, the reformed fuel B4 is supplied as the fuel is dried bamboo fuel chips. The air in the bamboo chips bag filter 29 is sucked out by transporting the fan 30, as combustion air A2, is supplied into the drying furnace in the third process of FIG. This has a lactic acid bacteria in bamboo, from the fact that such molds by corruption and put long starts fermentation and to chip also has a property that stink occurs, does not release the combustion air A2 to the atmosphere in the sense of odors, odor by placing in the furnace are of pyrolyzing purposes.
[0041]
　Incidentally transport fan 30, bamboo dehydrated chip silo 26 by air pressure in the air transport, so as not to flow back into the bamboo fuel chip silo 36, the transport air pressure gauge 55 as the transport air pipe becomes a negative pressure It is controlled. Also attach the transport air orifice 56 always in front of the transport air pressure gauge 55 so that the negative pressure.
[0042]
　It shows a system diagram of a third process of the present invention in FIG. An external input for the third process PR3 an external air A3, the reformed fuel B4 is dried bamboo fuel chips from the second process PR2 in Fig. 2, the combustion air A2, the first 1 a dehydrated water W2 from the process, the output to the outside from the third process PR3 is modified fertilizer D, exhaust air A4, a conveying air A1.
[0043]
　The third process is mainly composed of a drying oven 31. The drying furnace 31 includes a combustion air A2 or external air A3 is air used for combustion, the reforming fuel B4 is dried bamboo fuel chips as a fuel, is dried eligible dehydrated water W2 There has been turned on. Among not yet been described is a system of air A3. The system draws air outside air A3 valve 61, pushing the fan 27, heated air heater 28 is an air line LA2 that is configured of a combustion air regulating valve 32, the second 2 from a part of the air line LA2 branches of air lines LA1 of conveying air A1 toward the process.
[0044]
　The drying furnace 31 composed of a refractory material, drying the bottom of the stoker unit, introducing combustion air A2 and the outside air A3 is air used for combustion, in dried bamboo fuel chips as a fuel and by burning a reformed fuel B4. The drying furnace 31 which is formed in the combustion passage are installed spray nozzles 43, eluent spray control valve 42 the amount of dehydration water W2 adjusted by, are introduced into a spray on during the high temperature gas by combustion .
[0045]
　Hot exhaust gases are cooled subsequently led to the manure bag filter 47. Potassium fine bamboo powder and eluate in the eluate in the exhaust gas cooling process, chlorine, phosphorus, etc. becomes like potassium ion, is trapped in a fertilizer bag filter 47 along with bamboo powder. The lower portion of the fertilizer bag filter 47 is installed fertilizers extracted rotor 58, fertilizer D is turned into fertilizer FIBC 48. The ash component in the combustion exhaust gas is also collected in the same manner. The furnace bottom of the drying furnace 31 extracting ash generated in the combustion furnace bottom ash withdrawal rotor 57 is installed, is turned into fertilizer FIBC 48 as also fertilizers D periodically withdrawn ash.
[0046]
　Or more in order to effectively perform the manure collection in a third process PR3 described, various parts of the process PR1-PR3 is desirably is controlled as follows.
[0047]
　For example it is preferable to make the following with respect to controlling the dewatering water W2. Hot exhaust gas after combustion in the drying furnace 31 from the spray nozzle 43 installed in the furnace, since the exhaust gas is cooled by spraying the eluate pump 41 (FIG. 1) dehydration water W2 supplied from the bug controlling the flow rate of the dehydrated water W2 in the eluate spray control valve 42 so as to measure the exhaust gas temperature becomes a specified temperature at the filter inlet temperature gauge 44.
[0048]
　For example it is preferable to make the following with respect to controlling the reformed fuel B4. First, the level meter 15 signal Sa which is installed in the eluate tank T3 in FIG. 1 is fed is converted into speed control signal Sa1 against bamboo fuel chip supply rotor 37, the level meter 15 is less than a prescribed value for, by increasing the rotational speed of the bamboo fuel chip supply rotor 37 increases the bamboo fuel chip supply. Thus the amount of exhaust gas by reforming fuel B4 to be supplied to the drying oven 31 is increased to increase, acting in a direction to raise the bag filter inlet temperature. The bag filter inlet temperature since that will increase the amount of eluate W2 supplied to the spray nozzles 43 to a predetermined value in this state, as a result the level of the effluent tank T3 will be lowered. If conversely the level meter 15 instruction is lower than the specified value results in lowering the solution flow rate W2 decreases the combustion amount by reducing the rotational speed of the bamboo fuel chip feed rotor 37.
[0049]
　For example drying, it is preferable to make the following with respect to adjusting the combustion air A2 or external air A3 is air used for combustion. Again it is preferable to use the level gauge 15 signal Sa which is installed in the eluate tank T3 in FIG. Signal Sa level system 15, created as a preceding control signal Sa2 for the combustion air control valve 32 is applied, and the signal of the oxygen concentration meter 45 for measuring the oxygen concentration of the combustion air, a signal of the air flow meter 46 it is preferable to proactively control the proper amount of air in combination.
[0050]
　Above, three elements are placed in a drying furnace 31 has been described for recommended control strategy for (dehydrated water W2, reformed fuel B4, for combustion is air air A2 or external air A3 used for combustion).
[0051]
　Incidentally, it is noted below configuration and control other than the control of the main element. First, the exhaust gas exiting the fertilizer bag filter 47, after passing through the air heater 28, circulating water W3 and the heat exchanger of Figure 1 with a solution heater 49. The solution heater 49 is intended to return to the circulating water tank T1 again heated part in sampling the exhaust gas of the circulating water W3 from the circulation water pump P1 in FIG. Antifreeze in the cold region to return again circulating water tank T1 circulating water W3 warmed can be achieved, and it is possible to obtain a potassium eluted from bamboo chips by warming the circulating water W3 efficiently.
[0052]
　The inlet outlet of the solution heater 49 is provided with a solution heater temperature regulating valve 50, the temperature control is executed by the heater outlet temperature gauge 51. According to this, to increase the exhaust gas temperature of the heater outlet temperature gauge 51 by a solution heater temperature regulating valve 50 reduces the solution through a solution heater 49 opens if the following control values. On the other hand, if the temperature control abnormalities solution heater temperature regulating valve 50 is closed, increasing the solution passing amount of the solution heater 49.
[0053]
　Thereafter, the exhaust gas exiting the solution heater 49 is sent to the stack induced draft fan 52 enters the induction fan 52 is controlled so that the furnace pressure is controlled to the rotational speed by the signal of the furnace pressure gauge 60 at all times in a negative pressure ing.
[0054]
　Bamboo as the above-described fermentation by lactic acid bacteria offensive smell is generated begins when the chip. Thus since the silo after the chip, from the bent portion of such a tank could smell occurs, vent Manufacturing hold 59 is provided at the entrance of the push fan 27, connected each tank, the vent of the like silos ing. The vent Manual hold 59 is not closed, each tank has a part opened to the atmosphere, when there is internal pressure variation of the silo, and a negative pressure so as not out odor to the outside. When the internal vent Manufacturing hold 59 is under constant negative pressure or opened by the valve body negative pressure air suction valve 61, draws air from the atmosphere so that negative pressure does not drop to specified below. When the negative pressure is too low tank levels varies, and problems such as pulsation between the tank by the level variation of when the sealed tank is generated is generated. For this reason it is provided with the air suction valve 61.
[0055]
　Biomass reforming system according to the present invention is constructed basically as described above. Further, in this system, it is preferable to perform the control as described above. In the present invention, the structure described above, the utility of control will be described with reference to specific data below.
[0056]
　First, FIG. 4 shows a reuse data of the eluate. This shows the behavior data of the liquid in the potassium concentration in the case of re-use 6 times potassium eluate bamboo. Here, the number of reuse on the horizontal axis, the amount of water when the number of reuses the vertical axis (ml), the amount of bamboo (g), shows diluted (times), the potassium concentration (mg / l), respectively. This was eluted with 6 volumes of water bamboo weight, the eluted solution was reused a test result of repeated reuse again After eluting with new bamboo.
[0057]
　According to this result, it can be seen that potassium (K) concentration of about 1000 (mg / l) in a single elution increases, 6 times the concentration of potassium in the reuse increased in proportional relationship does not saturate there. Should this potassium content of bamboo is 0.79%, 7900 (mg / l) min amount is eluted into water reuse case of the included bamboo up to about half 3950 (mg / l) But, do not Nara be the case, there are more of elution. This saturation point by the difference in the potassium concentration bamboo from it can be seen that a possible re-use of the eluate by different should it but circulating water.
[0058]
　Figure 5 is a elution moisture more than 70% of the state of the bamboo shows the results of dehydration by centrifugal dehydrator 17. Shown here is dehydrated content and (thermostatic bath) and after dehydration conditions for bamboo. According to this result, up to about 40% by dehydrating reduced water, a sprinkle state. This is a wood raw chips equivalent moisture, which means that it is possible to use as fuel in dehydrated only. Therefore incidental facilities, such as drying oven 31 if there is such farms available eluate directly as liquid fertilizer cost can be understood to consist not necessary.
[0059]
　Figure 6 was analyzed whether one potassium fertilizers ingredient dehydrated solution was dried distillation residue and therein when eluted (K) phosphorus (P) nitrogen (N) are present much in bamboo and a long-jointed bamboo it is the result. According to this result, bamboo, a long-jointed bamboo be any material, the distillation residue is about to 8g present per 1 (l), potassium within its residue is present at about 3%. Phosphorus, nitrogen is a small amount, but the solution as shown in FIG. 4 is 6 times a minimum may be used, the potassium concentration is also a 6-fold concentration with simple minimum. Potassium definition fertilizer, phosphorus, is that the total nitrogen is higher than 6%, indicating a well that can be a fertilizer for potassium from about 3% is 18% of 6 times.
[0060]
　Figure 7 is a bamboo chip material, analysis and silica and calcium carbonate which is a high melting point substance in the elution only when added to the bamboo chips after elution (calcium carbonate) bamboo, a long-jointed bamboo and two bamboo analysis abroad the results show a.
[0061]
　In this case, we have taken up bamboo, a long-jointed bamboo, overseas bamboo 1, overseas bamboo 2 on the horizontal axis as a material. As evaluation items on the vertical axis, higher heating value, total water, air-dried sample water is taken ash, chlorine, potassium. Further, the softening point conditions for ash temperature, melting point, describes a temperature according to the flow point. It describes criteria further horizontal axis. In this table, as for the material for each material, the difference in each evaluation item after modification is represented by a number. Incidentally column modification, further, when the elution only when doped silica of 0.5%, when adding the silica 1%, are described separately calcium carbonate during the addition of 0.5%.
[0062]
　According to this result, the bamboo before modification of the raw materials, the determination value is evaluated as equivalent to the woody biomass (chlorine concentration of 0.1% or less, and a softening temperature of 1100 ° C. or more ash) with respect to the determination value Over. This means that not be the same combustion and woody biomass. Barely, only chlorine concentration of overseas bamboo 2 is equal to or less than the judgment value. In FIG. 7, a portion determination value or more portions surrounded by the thick frame, which is unsuitable factor for combustion.
[0063]
　As state after modification Turning first to the analysis result in the case of performing elution alone, overseas bamboo two becomes the criterion, but allows combustion without problems, bamboo, no problem chlorine concentration in a long-jointed bamboo but ashes softening temperature is less than the reference value.
[0064]
　In contrast, in the data when the case where silica was added in an amount of 0.5% and 1% of calcium carbonate was added 0.5% more bamboo from this state, that the softening temperature of the ash satisfies the criterion value understood. The softening temperature of the ash by Similarly, in a long-jointed bamboo adding silica 1% satisfies the determination value.
[0065]
　Figure 7 is represented by analyzing the ash which is the sum of the inorganic component. According to this, raw ash bamboo is 1.1%, ash content after elution ash is reduced by 0.6% next potassium compound is eluted. When this state is added 0.5% of silica ash is 1.1% of the raw material equivalent ash. That additive can be said that replacement material to compensate for the amount that potassium is eluted.
[0066]
　Figure 8 is a silica ash melting temperature and ash bamboo (SiO 2 ) and potassium oxide (K 2 shows the relationship between the ratio of O). The horizontal axis is silica in ash (SiO 2 ) and potassium oxide (K 2 is the ratio of O), In this figure, the horizontal axis of the silica in the ash (SiO 2 ) and potassium oxide (K 2 ratio of O), while indicating a range of 15% to 95%, for example, K is 35% 2 is O 65 SiO in% 2 indicates that the 35%.
[0067]
　SiO 9 2 and K 2 for eutectic phenomenon of O, K in ash 2 when O is present in small amounts melting temperature of the ash is known that the eutectic phenomenon significantly reduced to the point of the weighted average or less is generated There, since potassium is often the ash component of the bamboo, it summarizes by this diagram the index is 8.
[0068]
　Returning to FIG. 8, bamboo, a long-jointed bamboo, overseas bamboo 1, plotting the point of such a modified way after each modification overseas bamboo 2, it is also shown a line eutectic temperature characteristics of FIG. 9 by dotted lines. Results, but not comparable to literature values, a melting temperature characteristic of ash characteristics close, SiO 2 ratio K is between 30-70% 2 no change in the melting temperature of the ash varies the O concentration It is seen. In addition it can also be seen that are distributed in almost the same line regardless of the type of bamboo. Further, SiO 2 is in a ratio of 70% or more rapidly melting temperature increases. That it can be seen that polarization pole exists in the vicinity of 70%.
[0069]
　10 are those on the vertical axis and rearranged at the softening temperature from the melting temperature of the ash in a similar manner. Here also, the softening temperature for the same line regardless of the type of bamboo, organized by the same symbols, and subtracting the polynomial approximation line. As shown in FIG. 10, the softening temperature of the ash SiO 2 is polarized pole near the ratio 70%.
[0070]
