Description

Technical Field

[0001] This invention belongs to the field of air pollution control technology, specifically relating to a modular air pollution waste gas treatment device. Background Technology

[0002] The large amounts of waste gas generated during industrial production processes such as steel, chemical, power, coating, and building materials can pollute the atmosphere, making air pollution prevention and control particularly important.

[0003] Chinese patent application number 202520746705.1 discloses a waste gas treatment and recovery device based on air pollution prevention and control, including a purification tank and a filter tank. The purification tank is equipped with an air inlet, an air inlet pipe, and a guide pipe. The filter tank is equipped with a filter layer and an ultraviolet lamp. The purification tank is also equipped with a jet pipe, a spray pipe, a filtration structure, a heat exchange structure, and an air outlet. When the device treats and recovers waste gas, the waste gas sequentially enters the filter tank through the air inlet, air inlet pipe, and guide pipe of the purification tank. It is filtered by the filter layer of the filter tank and sterilized by the ultraviolet lamp. Then it returns to the spray pipe through the jet pipe. The spray pipe sprays a treatment solution for flocculation. The treatment solution is filtered by the filtration structure and then circulated for spraying. At the same time, the heat exchange structure exchanges heat with the circulated treatment solution. The waste gas after flocculation treatment is discharged through the air outlet.

[0004] The aforementioned existing technologies have the following problems: 1. The contact time between the waste gas and the treatment solution is short, which prevents sufficient flocculation and results in poor treatment effect; 2. The processing and filtration structures are dispersed, resulting in a large footprint; 3. Unable to accurately determine the condition of the treatment and filtration structures for maintenance and replacement; 4. Maintenance and replacement are relatively inconvenient.

[0005] In view of this, a modular air pollution exhaust gas treatment device is designed to solve the above problems. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides the following technical solutions: A modular air pollution exhaust gas treatment device, comprising: The exhaust gas treatment housing assembly includes a hollow exhaust gas treatment housing 101. The exhaust gas treatment housing 101 provides an installation structure for the exhaust gas treatment assembly, exhaust gas drying assembly, exhaust gas filtration assembly, assembly assembly, and exhaust gas discharge assembly. It also works with the exhaust gas treatment assembly, exhaust gas drying assembly, exhaust gas filtration assembly, assembly assembly, and exhaust gas discharge assembly to complete exhaust gas treatment and prevent air pollution. The exhaust gas treatment assembly includes two inspection ports 201 symmetrically located on the side walls of the exhaust gas treatment housing 101, and an exhaust gas treatment cylinder 202 disposed inside the hollow interior of the exhaust gas treatment housing 101. An exhaust gas treatment chamber 203 is formed inside the exhaust gas treatment cylinder 202. An exhaust gas inlet pipe 204 is located at the bottom of the exhaust gas treatment chamber 203. The inlet end of the exhaust gas inlet pipe 204 extends through to the outside of the exhaust gas treatment cylinder 202 and passes through the adjacent inspection port 201 to the outside of the exhaust gas treatment housing 101. At the bottom of the exhaust gas treatment chamber 203, below the exhaust gas inlet pipe 204, on both sides are respectively provided an absorbent liquid inlet pipe 205 and an absorbent liquid outlet pipe 206. The inlet end of the absorbent liquid inlet pipe 205 extends through to the outside of the exhaust gas treatment cylinder 202 and passes through the adjacent inspection port 201 to the outside of the exhaust gas treatment housing 101. The outlet end of the absorbent liquid outlet pipe 206 extends through to the exhaust gas treatment cylinder 202. The exhaust gas treatment cylinder 202 extends through the adjacent side inspection port 201 to the outside of the exhaust gas treatment housing 101. Several outlets 207 are evenly spaced at the top of the exhaust gas treatment cylinder 202. The absorbent inlet pipe 205 is connected to the circulation pump, which is connected to the absorbent processor. At the same time, the absorbent outlet pipe 206 is connected to the absorbent processor, which promotes the formation of a circulation between the absorbent inlet pipe 205, the exhaust gas treatment chamber 203, the absorbent outlet pipe 206, and the absorbent processor. The absorbent enters the exhaust gas treatment cylinder 202 through the absorbent inlet pipe 205 and is discharged through the absorbent outlet pipe 206, which keeps a constant amount of absorbent in the exhaust gas treatment chamber 203. The exhaust gas inlet pipe 204 is connected to a one-way check valve. The exhaust gas to be treated is passed through the exhaust gas inlet pipe 204 into the absorbent in the exhaust gas treatment chamber 203 for treatment. The treated exhaust gas rises and is discharged through several outlets 207, completing the exhaust gas treatment. The exhaust gas drying assembly includes two movable rings 301 symmetrically and movably fitted at both ends of the outer wall of the exhaust gas treatment cylinder 202. Two electric cylinders 302 are symmetrically fixed to the side wall of one movable ring 301 away from the other. Several U-shaped connecting frames 303 are fixedly connected at equal intervals along the circumference between the outer walls of the two movable rings 301. Telescopic arms 304 are hinged to both ends of each connecting frame 303. The telescopic arms 304 extend away from the connecting frame 303. A follower scissor frame 305 is movably arranged in the middle of the connecting frame 303. The sides of the telescopic arms 304 and the follower scissor frame 305 are adjacent to each other. The corner setting includes a connecting spring 306 fixedly connected to the bottom of the follower scissor frame 305. A mounting base 307 is hinged to the side of the telescopic arm 304 adjacent to the follower scissor frame 305. A flexible packing frame 308 is fixedly connected to the outer side of several mounting bases 307. Protective cotton 309 is fixedly sleeved on the outer wall of the flexible packing frame 308. During waste gas treatment, the treated waste gas undergoes preliminary drying through the flexible packing frame 308, and the dried waste gas undergoes secondary drying through the protective cotton 309. During maintenance and replacement, two electric cylinders 302 extend synchronously, driving the connected movable ring 301 to move on the waste gas treatment cylinder 202. The connected movable ring 301 drives another movable ring 301 to move on the exhaust gas treatment cylinder 202 via several connecting frames 303. When it moves to the inspection port 201 on the side away from the two electric cylinders 302, the inspection port 201 squeezes several telescopic arms 304 on the adjacent side. The telescopic arms 304 on the adjacent side press down and drive the connected follower scissor frames 305 to move. The follower scissor frames 305 drive the telescopic arms 304 on the far side to press down. The telescopic arms 304 drive the connected mounting seats 307 to move down. The mounting seats 307 drive the flexible packing. The frame 308 and protective cotton 309 retract inward and move to the outside of the exhaust gas treatment housing 101 through the maintenance port 201 on the side away from the two electric cylinders 302. Several connecting springs 306 reset, which drives several follower scissor frames 305 to reset, drives several telescopic arms 304 to reset, drives several mounting seats 307 to reset, and drives the flexible packing frame 308 and protective cotton 309 to expand and reset outward. The flexible packing frame 308 and protective cotton 309 are maintained and replaced. During the reset, the two electric cylinders 302 retract and reset synchronously, which drives the flexible packing frame 308 and protective cotton 309 to reset. The exhaust gas filtration assembly includes a filter cartridge 401 that is movably sleeved on the outside of the protective cotton 309. The exhaust gas after the protective cotton 309 has been dried twice is filtered through the filter cartridge 401. When the protective cotton 309 is removed during maintenance and replacement, it contacts the filter cartridge 401 and carries away the upper part of the filter cartridge 401 and the filtered impurities. The condition of the protective cotton 309 can be used to determine whether the filter cartridge 401 needs to be cleaned. The assembly includes two support slots 501 symmetrically located at both ends of the exhaust gas treatment cylinder 202, and a support frame 502 installed inside the inspection port 201. The cross-sectional area of ​​the inspection port 201 is larger than the sum of the cross-sectional areas of the exhaust gas treatment cylinder 202, the movable ring 301, the connecting frame 303, the telescopic arm 304, the flexible packing frame 308, the protective cotton 309, and the filter cylinder 401, but smaller than the cross-sectional area of ​​the support frame 502. The support frame 502 extends into the support slots 501 for support and is fixed to the filter cylinder 401 and the exhaust gas treatment housing 101 by bolts. The support frame 502 has mounting ports corresponding to the exhaust gas inlet pipe 204, the absorbent liquid inlet pipe 205, and the absorbent liquid outlet pipe 206, respectively. The exhaust gas inlet pipe 204, the absorbent liquid inlet pipe 205, and the absorbent liquid outlet pipe 206 pass through the corresponding mounting ports. Extending out of the exhaust gas treatment housing 101, two electric cylinders 302 are fixedly connected to the adjacent side support frame 502, and their output ends extend through the support frame 502 into the interior of the exhaust gas treatment housing 101 and are fixedly connected to the adjacent side movable ring 301. During exhaust gas treatment, the two support frames 502 support the exhaust gas treatment cylinder 202 and the filter cylinder 401 for exhaust gas treatment. When the flexible packing frame 308 and the protective cotton 309 are maintained or replaced, one side support frame 502 is removed, and the other side support frame 502 continues to support the exhaust gas treatment cylinder 202 and the filter cylinder 401. The flexible packing frame 308 and the protective cotton 309 are removed from the disassembly side inspection port 201 for maintenance or replacement. When the exhaust gas treatment cylinder 202 and the filter cylinder 401 are maintained or replaced, the two side support frames 502 are removed, and the exhaust gas treatment cylinder 202 and the filter cylinder 401 are taken out for maintenance or replacement. The exhaust gas discharge assembly includes an exhaust gas outlet pipe 601 fixed to the top of the exhaust gas treatment housing 101 and connected thereto. The filtered exhaust gas is discharged through the exhaust gas outlet pipe 601 to prevent air pollution.

[0021] Working principle of the invention: During exhaust gas filtration, the absorbent inlet pipe 205 is connected to a circulation pump, which in turn is connected to an absorbent processor. Simultaneously, the absorbent outlet pipe 206 is connected to the absorbent processor, creating a circulation between the absorbent inlet pipe 205, the exhaust gas treatment chamber 203, the absorbent outlet pipe 206, and the absorbent processor. The absorbent enters the exhaust gas treatment cylinder 202 through the absorbent inlet pipe 205 and is then discharged through the absorbent outlet pipe 206, ensuring a constant amount of absorbent remains in the exhaust gas treatment chamber 203. The exhaust gas inlet pipe 204 is connected to a one-way check valve. The exhaust gas to be treated is fed into the absorbent in the exhaust gas treatment chamber 203 through the exhaust gas inlet pipe 204 for treatment. The treated exhaust gas rises and is discharged through several outlets 207. The treated exhaust gas undergoes preliminary drying through a flexible packing frame 308, followed by secondary drying through protective cotton 309. After secondary drying, the exhaust gas is filtered through a filter cylinder 401 and discharged through an exhaust gas outlet pipe 601, completing the exhaust gas treatment and preventing air pollution. When maintaining or replacing the flexible packing frame 308 and protective cotton 309, disassemble the support frame 502 on the side away from the two electric cylinders 302. The two electric cylinders 302 extend synchronously, driving the connected movable ring 301 to move on the exhaust gas treatment cylinder 202. The connected movable ring 301 drives another movable ring 301 to move on the exhaust gas treatment cylinder 202 through several connecting frames 303. When it moves to the inspection port 201 on the side away from the two electric cylinders 302, the inspection port 201 squeezes several telescopic arms 304 on the adjacent side. The telescopic arms 304 on the adjacent side press down and drive the connected follower scissor frames 305 to move. The follower scissor frames 305 drive the connected telescopic arms 304 on the side away to press down. The telescopic arms 304 drive the connected mounting seats 307 to move down. Mounting base 307 drives the flexible packing frame 308 and protective cotton 309 to retract inward, and move them to the outside of the exhaust gas treatment housing 101 through the maintenance port 201 on the side away from the two electric cylinders 302. Several connecting springs 306 reset, driving several follower scissor frames 305 to reset, driving several telescopic arms 304 to reset, driving several mounting bases 307 to reset, and driving the flexible packing frame 308 and protective cotton 309 to expand and reset outward. The flexible packing frame 308 and protective cotton 309 are maintained and replaced. At the same time, the condition of the protective cotton 309 can be used to determine whether the filter cartridge 401 needs to be cleaned. During the reset, the two electric cylinders 302 retract and reset synchronously, driving the flexible packing frame 308 and protective cotton 309 to reset. The support frame 502 on the side away from the two electric cylinders 302 is installed to complete the maintenance and replacement. When maintaining or replacing the exhaust gas treatment cylinder 202 and the filter cylinder 401, remove the support frames 502 on both sides, take out the exhaust gas treatment cylinder 202 and the filter cylinder 401 for maintenance or replacement, and then install the support frames 502 on both sides to complete the maintenance or replacement.
