[1]The present invention relates to an additive manufacturing facility comprising relates to additive production equipment comprising the distillation apparatus, and this, one is more specifically to discharging of the produced additive facilitates the distillation apparatus and it.
BACKGROUND
[2]To produce the coke blend by adding a binder to the number of kinds of the combined carbon coal is blended in, and the dry distillation by charging it to a coke oven. The binder serves to, by the time the contents in the oven burnt combination, enhance the charge density of the blended carbon, increase the strength of coke. As binder, a method using a tar (tar) or the extraction and use of jeomgyeol components from the coal are used.
[3]
By the way, there is a problem that generates a load in use, and the odor after the step of tar (tar) as binder, difficulties in normal operation the coke produced. These problems are mainly due to the crude diesel and naphthalene, which are materials of a low boiling point contained in the tar (Naphthalene). Thus, in general, heat-treating the tar from the distillation column, and is accompanied by a step of removing tar reforming by separating a naphthalene and tar from the tank via.
[4]
The boiling point of the naphthalene is approximately 180 ℃ to 230 ℃, since landscaping significant boiling point is lower, by heating the tar at a temperature above the boiling point of the naphthalene, landscaping oil is first gasified and discharged to the top of the distillation column, is naphthalene the gasification in the next distillation column It is from the discharge. And thereby discharging the naphthalene and landscape oil tar is removed from the bottom of the distillation column.
[5]
By the way, if the density is low, and landscape naphthalene oil removed from the tar, to increase the amount of the viscosity-modified tar leaving only the components due to the high density, high viscosity is a factor that prevents the reforming tar is fed to the distillation column bottom. Therefore, conventionally, by heating the tar at a temperature of 300 ℃ excessively higher than the boiling point of the naphthalene, separating a naphthalene and crude light oil, it was removed to facilitate the lowering the viscosity of the tar is discharged. That is, since the need to heat the tar in unnecessarily high temperature than the temperature for separation of the naphthalene, and the load which caused the distillation process occurs, there is a problem that much energy consumption is large.

Thus, naphthalene and landscaping significant separation efficiency is improved by the heat of the hot air is passed evenly into the distillation apparatus 300, uniformly delivered by the rotation and a plurality of nozzles (331c) of the impeller 330, so that naphthalene and can be reduced compared with the content of the tank via a conventional component, it is produced, the quality improved additives.
[64]
In addition, the embodiment of the present invention, can be gathered, because the additive is to rotate the blade 331 within the lower body (312), stirring the additive continuously inside the lower body (312). Accordingly, the additive in the lower body 312, it is possible to prevent condensation and resulting viscosity increase, the effect that the lower outlet is easy to the additives discharge pipe 31 connected to the lower body 312, due to the low viscosity.
[65]
And, conventionally, distilled tar fractionation in a hot air having an excessively high temperature of 300 ℃ than naphthalene boiling point in the distillation unit, to prevent the viscosity of the additive increases. In this case, there is a problem in the power and the time for adjusting the hot air to 300 ℃ is further consumed. However, since in the present invention to prevent the viscosity of the additive increases by a rotation of the impeller 330, it is possible to reform the tar at a low temperature, for example, hot air of 230 to 180 ℃ ℃ compared to the prior art. Therefore, it is possible to reduce than the power and time for adjusting the temperature of the hot air supplied to the distillation apparatus 300 in the prior art.
[66]
In addition, due to its heat of is generated at the time of heating the waste gas passing through the flue is usually 180 ℃ to 230 ℃ of the coke oven (10) for coke production, the waste gas with no additional temperature necessary to adjust the distillation apparatus 300, It can be used to supply a hot air. Thus, shortening the time for the temperature control of the hot air or hot air production and can reduce the cost, thereby reducing the time and cost for modification of the tar from the distillation apparatus (300).
[67]
Additives discharge pipe 31 has a lower, more particularly, the reactor 310 is connected to the lower end of the lower body 312, thereby discharging the additive to the outside. Such additives discharge pipe 31 has one end connected to the lower end of the lower body 312 is, and the other end connected to the additive storage section 80, the pumping means (31a) for imparting a moving force, the additive outlet tube 31. Additive this may be connected.
[68]
Additives discharge pipe 31 is additive to the outermost lower end of the lower body (312) that when the inner diameter of the shape is narrowed, the lower body 312 are connected to the lower end, the lower body 312 toward the lower side of as described above, the discharge pipe 31, it is preferred that the connection. Then, the lower body (312) is a non-symmetrical shape as described above, the outermost lower end is at a position deviated from the widthwise center of the lower body (312). Thus, the additive outlet pipe 31 connected to the outermost lower end is connected to a position deviated from the widthwise center of the lower body (312). In other words, the additives discharge tube according to an embodiment 31 is connected to the lower end of the lower body 312 is deviated from the widthwise center of the lower body (312). According to which the additives (reforming tar) gather in the lower body 312 is discharged through the discharge pipe additive, the effect of reducing the congestion of a mobile additive. In other words, when compared with the additive outlet pipe 31 is connected to the right and left center in the width direction, is located away to the center, to the identity of the additive movement reduced, and the effect that the discharge is easy.
[69]
And, since the installation such that the widthwise center of the blade 331 is located at the widthwise center of the lower body 312, when the additive outlet tube is located in a widthwise center, the additive is released into rotating force by the blades and the additive outlet tube the screw rotational force generated when the overlap or clash, the delay time the additive is released into the additive discharge can be generated.
[70]
However, in the present invention, connected to a position in the width direction center is installed at the widthwise center of the lower body 312, and additive outlet tube 31 of the blade 331 is deviated from the widthwise center of the lower body (312) Accordingly, the congestion due to the rotation of the blade 331 is minimized or prevented.
[71]
In the above-described, for example, a distillation apparatus for separating a naphthalene and crude light oil. But it not limited to separate materials, distillation apparatus according to the embodiment of the present invention can be applied to a variety of distillation apparatus using a fractionation method using a boiling point difference by supplying hot air.
[72]
[73]
Or less, 1 to 3, description will now be an additive manufacturing method using an additive manufacturing apparatus according to an embodiment of the present invention.
[74]
Removing the tar (modified before tar) in the coke oven gas is de Kendal 20 is discharged through the rising pipe of the coke oven 10, and the tar of the separated liquid from the de-Kendal 20 is supplied to the top side of the distillation unit do.
[75]
When the tar is put in the upper side of the reactor, the distillation apparatus 300, the tar is moved along a plurality of trays disposed arranged in the lower side from the tray 320 located at the most image side 320, and a guide member 340. At this time, since the plurality of trays 320 is arranged so biased alternating or in the width direction in a zigzag pattern, to the respective tray 320 and one side wall of the upper body and the other side wall, each of the spaced-apart space in the passage, as the tar zigzag Over moves downward toward the lower body (312).
[76]
And this tar is charged to supply the flow while moving to the lower side, hot air into the distillation apparatus 300. That is, the supplying hot air to the lower body a blade 331 provided inside 312, and ejecting the hot air through a plurality of nozzles (331c) provided in the blade 331, the embodiment, by rotating the blade 331, a hot-air the supplies.
[77]
Hot air is supplied to the distillation apparatus 300 having a temperature of 180 ℃ to 230 ℃, separated by landscaping oil first gaseous low boiling point from the tar by the heat of a hot-air tank after the move to the top of the distillation apparatus (300) through the discharge pipe via 32 it is discharged to the tank through the absorption column. Then, there is a higher boiling point than oil landscaping naphthalene is separated in a gaseous state, go to the image side, and a side wall between the top and the bottom of the reactor 310, e.g., discharge through a naphthalene discharge pipe 33 connected to a central portion in the vertical direction.
[78]
So in the present invention, according to supply a heat source into the distillation apparatus, since the supply by rotating the blades 331 is injected through a plurality of nozzles (331c), the reactor 310 may be a uniform heat source hot air delivered to the interior . Accordingly it made in contact with the tar and ten won the hot air uniformly, so that it is possible to improve the separation efficiency in mind naphthalene and landscape. Therefore less naphthalene and landscaping significant amount, it is possible to manufacture a high-quality additives do not have a bad smell from the room temperature, it is possible to reduce or minimize the pressure difference increases and clogs the pipe, cooling by naphthalene.
[79]
And, as a tar injected upwardly moved to the lower side the lower body 312 is located, naphthalene, and landscape and collects in the internal oil separation Modified tar it is lower body 312, the lower body inside the impeller 330, ejecting the hot air and while it is rotating. This can be due to heat by hot air jet, and that the rotational force of the blade 331, preventing the condensation and thereby the viscosity of the produced additive increases. Thus, the additives collected in the lower body 312 is discharged easily through the additive outlet tube.
[80]
To do this, in the present invention, even with a hot air of a temperature lower than the conventional, it is possible to remove the naphthalene, and the viscosity of the additive tank via while preventing the rise. This can be reduced compared with the conventional electric power and the time for adjusting the temperature of the hot air supplied to the distillation apparatus.
[81]
In addition, embodiments the COG which is discharged from the distillation apparatus 300 at a low temperature 180 ℃ can be modified process the tar in to 230 ℃, coke oven 10 in the hot air to be fed into the reactor than the conventional through the flue It can be used. Thus, shortening the time for the temperature control of the hot air or hot air production and can reduce the cost, thereby reducing the time and cost for modification of the tar from the distillation apparatus.
