DETAIL DESCRIPTION OF INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS OF THE PREFERRED EMBODIMENTS:
[0050] While the embodiments of the disclosure are subject to various modifications and alternative forms, a specific embodiment thereof has been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure.
[0051] The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a device, system, assembly that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in a system or device proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or device.
[0052] The present invention is related to an Air Pollution Control Tower (APCT) for air purification up to 80000 cubic meter volume of air per hour and a method of air purification by APCT.
[0053] Referring to Figure 1 and Figure 2, illustrating sectional and isometric views of air pollution control tower (100). The air pollution control tower (100) is provided on a strong civil foundation. Further, the air pollution control tower (100) has self-supporting structure with spiral stair case (109) with gritted type platform in the respective chamber which are needed during maintenance time.
[0054] The APCT (100) comprises of a base chamber (101), a dust collecting chamber (102), a first pressure development chamber (103), a carbon filter chamber (104), a second pressure development chamber (105), an axial fan chamber (106), a third pressure development chamber (107) and deflector openings (108).
[0055] Referring to Figure 3, the base chamber (101) has a plurality of openings (301), i.e. approximately 16 for providing entry of polluted air. Each of these plurality of openings (301) has demister pads (302) provided to eliminate dew/fog and other floating contaminants present in the polluted air. Also, the demister pads (302) restrict the entry of birds from entering inside the tower (100). The demister pads (302) are fitted with locking arrangements (303) over the plurality of openings (301). In an embodiment, at geographical locations like southern parts of India, a coarse mesh (302) is used for restricting the floating contaminants of polluted air and birds.
[0056] The pleated filters (304) are fitted on a steel plate (305) with suitable fixing arrangements which are placed behind the demister pads (302) to remove the particulate matter from the polluted air that is passed through the demister pads (302). There are approximately 32 pleated filters (304) fitted in four segments and each of the pleated filters (304) is a polyester type pleated filter which is capable of removing particulate matter up to 2 micron with high efficiency (PM 2, 99.9% efficiency).
[0057] Considering the ambient air input, the pleated filter (304) provides maximum air to cloth ratio within a small area. The increased air to cloth ratio, reduces the total system sizes in area requirements, as well as other accessories and components which attracts much cost reduction. The base chamber (101) is capable of handling 1920,000 cubic meter volume of air per day.
[0058] Referring to Figure 4, a dust collecting chamber (102) is provided below the pleated filter (304) to collect accumulate/store the dust particles collected in the pleated filters (304) from the polluted air. The dust collecting chamber (102) is a hopper and has a zig-zag passing route (401) which passes the dust collected by the pleated filter (304) towards the dust collecting chamber (102) only and restrict the flow of dust in the reverse/upward direction. Due to high pressure compressed air at 6-8 bar and gravity of dust, the dust falls down and gets accumulated in the dust collecting chamber (102). During every Auto cleaning time with respect to predefined data, the hopper passes the dust in the zig-zag passing route (401) as shown in figure towards the silo. As the dust accumulation is very less, zig-zag passing route (401) is effective.
[0059] Referring to Figure 5, the first pressure development chamber (103) is provided above the base chamber (101). The first pressure development chamber (103) is provided to develop pressure in the filtered air that comes out from the base chamber (101) and uniformly distributes the filtered air before processing the air in the carbon filter chamber for odour and toxic gas treatment.
[0060] An auto cleaning system is provided at bottom of the first pressure development chamber (103) to clean the pleated filters (304) periodically. The auto cleaning system has a pulse jet cleaning arrangements with a compressor header and solenoid valves along with timer arrangements. In an aspect, the pulse cleaning duration is maximum and pressure & volume requirements are lower which increase the effectiveness of the cleaning operation.
[0061] The solenoid valves are fitted along with a header tank and the valves are provided at the bottom line of the first pressure development chamber (103) on the outer side. High pressure compressed air from the compressor header is exerted periodically into the various row/line of the pleated filters (304) by operating the solenoid valves in order and for cleaning the accumulated dust and contaminants.
[0062] The dust and contaminants from the pleated filters (304) is directed towards the dust collecting chamber (102) from where the dust is removed from the APCT (100) without releasing the dust in the environment. The advantage of providing auto cleaning system is that there is no need for manual maintenance and intervention for cleaning. Further, the whole air pollution control tower (100) works efficiently for longer time and there is no untimely choking of the pleated filters (304).
[0063] The compressor header is placed near the silo zone aside along with a control panel. In an embodiment, the compressor header is programmed in such a manner that the compressor header will run approximately 10 minutes before the pursing cycle starts to develop the required air pressure at the manifold and stopped once the cleaning cycle is completed. Considering the dust load of ambient air 3- 4 hours gap is required between two consecutive pursing cycle, hence to save the electricity and running cost the above condition is used.
[0064] Referring to Fig. 6, the carbon filter chamber (104) is provided for treating the odour and toxic gas. The carbon filter chamber (104) has an activated regenerative type carbon filters (601). There are approximately 48 V-type configuration activated type carbon filters (601) fitted in the carbon filter chamber (104). These carbon filters (601) remove volatile organic compounds such as odour, Sox, Nox and other toxic gases that float in the atmosphere. The position of the carbon filters (601) increases the dwell time of air contact with the carbon molecules for better efficiency. Also, the regenerative type carbon filters (601) reduce the operating cost of the carbon filters (601) and subsequently reduces the running cost of the tower (100).
[0065] Referring to Fig. 7(a), 7(b), 7(c), the purified air from the carbon filter chamber (104) passes through a second pressure development chamber (105) for smoothening and uniformity flow. The purified air is made to enter an inlet of a conical duct (703) to pass the purified air to an inlet silencer (704) which is approximately 700 mm long. A fan is fitted with the inlet silencer (704) and another fan is provided at an outlet silencer (701) which is approx. 500 mm long and is provided to reduce the noise to 65 dbA.
[0066] Referring to Fig. 8 and Fig. 9, the air is sucked by the axial fan chamber (106) where at least four fans (705) with at least four inlet silencers (704) and four outlet silencers (701) are fitted in total. The fans (705) create a high static pressure inside the second pressure development chamber for streamlining the flow of air from the base chamber to the axial fan chamber (106) which is around 200 mm water column.
[0067] The axial fan chamber (106) also has an acoustic cladding provided inside the inner wall of the axial fan (705) for further noise reduction. The noise created in the axial fan (705) is cancelled by the silencers (701, 704) and the acoustic cladding present inside the axial fan chamber (106) and bring it down to an acceptable limit. The in and out circulation of the air from the air pollution control tower (100) is maintained by the axial fan (705) of the axial fan chamber (106).
[0068] The purified air sucked by the axial fan chamber (106) is passed into the third pressure development chamber (107) for flow uniformity during exit. Hence the clean air passes through a convergent divergent path is released at a deflector openings (108). The top portion of the deflector opening (108) or exit zone is fitted with a canopy to restrict the water and bird entry and the bottom portion of the canopy is fixed by convex type cone to divert the air stream flow towards opening that are present at periphery without any obstruction.
[0069] In an embodiment rain detectors are provided on the air pollution control tower (100) to detect the rain. In the event of rain, the rain detectors will shut down the air pollution control tower (100). It does not only save the energy but also avoid chocking of the pleated filters (304) due to entry of water in the air pollution control tower (100).
[0070] In another embodiment, the fans (705) are connected with single soft starter with timer setting. The Gritted types platform (110) are used with the self-supported air pollution control tower (100) according to aesthetic point of view after due analysis in the structural analysis. Based on the wind load throughout the year of the particular region and climate behaviors this design is effective for continuous operation and air pollution reduction.
[0071] There are two manholes available in each platform from maintenance point of view with suitable air locking arrangements. The circular single pole gritted stair case is used for climbing for maintenance activity and each platform is inter connected with the stair case (109) accordingly.
[0072] Referring to Figure 10, a method (1000) of air purification by an air pollution control tower (100) is provided. The polluted air is passed (1001) through demister pads (302) which have a 1-meter x 0.5-meter rectangular opening for removing dew/fog and other floating contaminants of polluted air. Also, the demister pads (302) restrict the entry of birds from entering the air pollution control tower (100). The demister pads (302) are fitted with locking arrangement (303) over the plurality of openings (301).
[0073] In the second step (1002), the air is passed from the demister pads (302) through multiple pleated filters (304) for removing particulate matter up to 2 micron with high efficiency (PM 2, 99.9% efficiency).
[0074] In the third step (1003), the filtered air from the pleated filters (304) is sent into a first pressure development chamber (103) to develop ambient pressure in the filtered air and to uniformly distribute the filtered air for processing. This step is done to remove odour and toxic gases. An auto cleaning system is provided at bottom of the first pressure development chamber (103) to clean the pleated filters (304) periodically. The auto cleaning system has a pulse jet cleaning arrangement with the compressor header and solenoid valves along with timer arrangements. The high pressure compressed air that comes out from the compressor header is exerted periodically into the various row/line of pleated filters (304) by operating the solenoid valves in order to clean the accumulated dust and contaminants.
[0075] In the fourth step (1004), the filtered air is passed from the first pressure development chamber (103), which is sent to a carbon filter chamber (104) for removing volatile organic compounds such as odour, Sox, Nox and other toxic gases which are floating in the atmosphere. The activated type carbon filters (601) have a V configuration that aids in increasing the dwell time of air contact with the carbon molecules.
[0076] In the fifth step (1005), the purified filtered air from the carbon filter chamber (104) is passed to the the axial fan chamber (106) for processing by conical duct (703) to link the purified filtered air to the inlet silencer which is 700 mm long. A high static pressure by the axial fan chamber (106) is created for providing a streamline flow of air. The noise created in the axial fan (705) is cancelled by the silencers and acoustic cladding present inside the axial fan chamber (106) and bring down to an acceptable limit. The in and out circulation of the air from the air pollution control tower (100) is maintained by the axial fan (705) of the axial fan chamber (106).
[0077] In the last step (1006), the purified air sucked by the axial fan chamber (106) is passed into a third pressure development chamber (107) for flow uniformity during the exit of the purified air. Hence, the purified air/clean air passes through a convergent path and releases at the periphery deflector openings (108) and into the surroundings.
[0078] The materials are given as example without restricting scope of the invention to the same. Thus, other materials readily apparent to a person skilled in the art are understood to be within purview of the invention.
