Description

Technical Field

[0001] This invention belongs to the field of industrial exhaust gas treatment technology, and specifically relates to a high-efficiency post-treatment device for industrial exhaust gas purification. Background Technology

[0002] Industrial exhaust gas refers to the collective term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, carbon monoxide, soot, and industrial dust, etc. Direct discharge into the atmosphere will cause serious air pollution, therefore purification treatment is necessary.

[0003] Currently, Chinese invention patent CN117065549B discloses an industrial exhaust gas dust removal and purification device, including a liquid storage tank for storing neutralizing liquid; it also includes an exhaust pipe fixedly installed at the center of the top side of the storage tank, with the interior of the exhaust pipe communicating with the interior of the storage tank. A filtration mechanism is provided inside the storage tank, inside the exhaust pipe, and on the outer periphery of the exhaust pipe, filtering harmful substances from the industrial exhaust gas. This improved industrial exhaust gas dust removal and purification device achieves strong purification by maximizing the contact area and duration between the industrial exhaust gas and the neutralizing liquid during industrial exhaust gas treatment. Furthermore, the device eliminates the need for filter cartridges to ensure effective impurity removal, reducing operating costs. Simultaneously, the large amount of particulate impurities adhering to the inner wall of the tank reduces cleaning workload for the user. The device also consumes little electricity and is highly environmentally friendly during operation.

[0004] Existing industrial exhaust gas purification methods generally require specific steps such as pre-desulfurization, pre-denitrification, and spraying, depending on the type of industrial exhaust gas. Regardless of the type of industrial exhaust gas, post-adsorption purification is necessary after the pretreatment process. This not only reduces particulate matter in the exhaust gas but also adsorbs odors and bacteria. To improve efficiency, existing industrial exhaust gas adsorption purification devices typically use two or more adsorption towers in alternating cycles. While one tower is in use, another can undergo cleaning and regeneration. However, this adsorption method requires significant space, and multiple adsorption towers need to be connected and controlled via different pipelines and valves to ensure simultaneous and alternating adsorption and regeneration. This is not only cumbersome to operate but also results in significant regeneration gas loss, impacting the efficiency of post-treatment purification of industrial exhaust gas. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency post-treatment device for industrial exhaust gas purification. Its advantages are that it facilitates the adsorption and regeneration of exhaust gas by a single tower, improves the purification efficiency of industrial exhaust gas post-treatment, and reduces gas loss during regeneration.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a high-efficiency post-treatment device for industrial exhaust gas purification, comprising an exhaust gas adsorption tower, wherein an intermediate column is welded inside the exhaust gas adsorption tower, and a sliding sleeve is slidably sleeved on the surface of the intermediate column; an air inlet pipe and a sealing pipe are respectively fixedly connected to the top and bottom of the exhaust gas adsorption tower; and an adjustment mechanism and a cleaning mechanism that cooperate with the sliding sleeve are respectively provided inside the exhaust gas adsorption tower.

[0007] Using the above technical solution, a rotating drive motor drives the sliding sleeve to rotate 180° inside the tail gas adsorption tower. This allows the tail gas adsorption cotton on both sides of the sliding sleeve to alternately connect with the inlet and outlet pipes, thus adsorbing and purifying the industrial tail gas. The tail gas adsorption cotton on both sides of the sliding sleeve is separated by a partition plate, forming independent spaces to prevent the industrial tail gas from flowing between them. This improves the post-treatment purification efficiency of industrial tail gas and reduces the space occupied by the equipment. By closing the outlet pipe, gas enters the sliding sleeve through the connecting slot, causing clean gas to move from the tail gas adsorption cotton on the other side, which is not currently adsorbing, carrying away impurities and foreign objects inside the adsorption cotton and discharging them through the return gas pipe. This facilitates single-tower adsorption purification and clean regeneration of tail gas, reducing gas loss during regeneration.

[0008] The invention is further configured such that: the adjusting mechanism includes a drive motor bolted to one side of the surface of the exhaust gas adsorption tower; a fixed plate is welded to the bottom of the sliding sleeve; a semi-circular conical toothed ring is fixedly fitted to the top of the fixed plate and is fitted with the sliding sleeve; a bevel gear meshing with the semi-circular conical toothed ring is bolted to the output end of the drive motor; exhaust gas adsorption cotton is filled on both sides inside the sliding sleeve; a spacer plate welded to the sliding sleeve is provided between the two exhaust gas adsorption cottons; an exhaust pipe is fixedly connected to one side of the sealed pipe opening; a first solenoid valve is bolted to the end of the exhaust pipe away from the sealed pipe opening; an exhaust pipe hole is fixedly connected to the surface of the exhaust pipe at the end inside the sealed pipe opening; an intake pipe hole is fixedly connected to the bottom end of the intake pipe; ventilation holes communicating with the intake pipe hole and the exhaust pipe hole are respectively opened at the top and bottom of the two exhaust gas adsorption cottons on the inner wall of the sliding sleeve; a connecting groove is opened inside the intermediate column; and the bottom of the inner cavity of the intermediate column is connected to the exhaust pipe through the connecting groove.

[0009] By adopting the above technical solution, the exhaust gas adsorption cotton on both sides of the sliding sleeve can be alternately connected to the inside of the inlet pipe and the outlet pipe to adsorb and purify industrial exhaust gas, thereby improving the post-treatment purification efficiency of industrial exhaust gas.

[0010] The invention is further configured such that: the cleaning mechanism includes a sealing piston that is slidably inserted into the middle column near the end of the air outlet pipe; a lifting plate is adhered to the top of the sealing piston; a return spring fixedly connected to the middle column is bolted to both sides of the bottom of the second solenoid valve; an air inlet hole is provided at the top of the surface of the middle column at the end of the air inlet pipe away from the air inlet hole; the top of the connecting groove is interconnected with the top of the inner cavity of the sliding sleeve through the air inlet hole and the vent hole; a return air hole is provided at the bottom of the surface of the middle column at the end of the air outlet pipe away from the air outlet hole; the interior of the sealing pipe is interconnected with the bottom of the inner cavity of the sliding sleeve through the cooperation of the return air hole and the vent hole; a return air pipe is fixedly connected to the bottom of the sealing pipe away from the air outlet pipe; and a second solenoid valve is bolted to the end of the return air pipe away from the sealing pipe.

[0011] By adopting the above technical solution, the clean gas moves inside the exhaust gas adsorption cotton, carrying away impurities and foreign objects, which facilitates the adsorption, purification and regeneration of exhaust gas by a single tower, and reduces gas loss during regeneration.

[0012] The present invention is further configured such that: a heat-conducting ring sleeve is slidably sleeved on the surface of the sliding sleeve and bolted to the tail gas adsorption tower, and an electric heater electrically connected to the heat-conducting ring sleeve is bolted to one side of the outside of the tail gas adsorption tower.

[0013] Using the above technical solution, the heat-conducting annular sleeve is heated by turning on the electric heater, thereby increasing the temperature of the exhaust gas adsorption cotton inside the sliding sleeve. This allows the exhaust gas adsorption cotton to sterilize and disinfect the passing exhaust gas at high temperature. Simultaneously, the exhaust gas adsorption cotton can also be dried to prevent moisture in the exhaust gas from adsorbing onto its surface.

[0014] The present invention is further configured such that: the top of the exhaust gas adsorption tower is provided with a connecting pipe that is fixedly connected to the air inlet pipe.

[0015] The above technical solution facilitates the connection of industrial exhaust gas pipelines, allowing industrial exhaust gas to be transported to the exhaust gas adsorption tower for purification treatment through connecting pipelines and inlet pipelines.

[0016] The present invention is further configured such that a sealing ring, which works in conjunction with the vent hole, is bonded between the surface of the intermediate column and the inner wall of the sliding sleeve.

[0017] By adopting the above technical solution, the sealing performance of the vent connection is improved, preventing industrial exhaust gas from leaking from the gap between the intermediate column and the sliding sleeve.

[0018] The present invention is further configured such that: both sides of the top and bottom of the inner cavity of the exhaust gas adsorption tower are rotatably connected to supporting ball bearings that are slidably connected to the sliding sleeve.

[0019] By adopting the above technical solution, the frictional force of the sliding sleeve when it rotates inside the tail gas adsorption tower is reduced, and the rotational stability is improved.

[0020] The present invention is further configured such that: both sides of the surface of the intermediate column are bolted with limit springs, and a conical block is fixedly connected to one end of the limit spring near the sliding sleeve; both sides of the inner wall of the sliding sleeve are provided with conical slots that slide and insert into the conical block.

[0021] By employing the above technical solution, the conical locking block is inserted into the conical slot using the elastic force of the limiting spring, thereby limiting and fixing the sliding sleeve. This prevents the sliding sleeve from shifting after rotational adjustment, improving the accuracy of the vent connection. Simultaneously, when the sliding sleeve rotates, the inclined surfaces of the conical locking block and the conical slot engage, causing the conical locking block to automatically retract into the intermediate column under pressure, overcoming the elastic force of the limiting spring.

[0022] The present invention is further configured such that support legs are bolted to the four corners of the bottom of the exhaust gas adsorption tower.

[0023] By adopting the above technical solution, the stability of the tail gas adsorption tower is improved, which facilitates the purification and treatment of industrial tail gas.

[0024] In summary, the present invention has the following beneficial effects: 1. A rotating drive motor drives the sliding sleeve to rotate 180° inside the exhaust gas adsorption tower. This allows the exhaust gas adsorption cotton on both sides of the sliding sleeve to alternately connect with the inlet and outlet pipes, thus adsorbing and purifying the industrial exhaust gas. The exhaust gas adsorption cotton on both sides of the sliding sleeve is separated by partitions, forming independent spaces to prevent the industrial exhaust gas from flowing between them. This improves the post-treatment purification efficiency of industrial exhaust gas and reduces the space occupied by the equipment. 2. By closing the outlet pipe, gas enters the sliding sleeve through the connecting groove, allowing clean gas to move from the other side of the exhaust gas adsorption cotton, which is no longer engaged in adsorption. This carries away impurities and foreign objects from inside the exhaust gas adsorption cotton and discharges them through the return gas pipe. This facilitates adsorption purification and clean regeneration of exhaust gas using a single tower, reducing gas loss during regeneration. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A high-efficiency post-treatment device for industrial exhaust gas purification includes an exhaust gas adsorption tower 1. An intermediate column 4 is welded inside the exhaust gas adsorption tower 1, and a sliding sleeve 5 is slidably fitted onto the surface of the intermediate column 4. An inlet pipe 3 and a sealing port 2 are respectively fixedly connected to the top and bottom of the exhaust gas adsorption tower 1. An adjustment mechanism 6 and a cleaning mechanism 7, which cooperate with the sliding sleeve 5, are respectively installed inside the exhaust gas adsorption tower 1. A drive motor 601 rotates the sliding sleeve 5 180° inside the exhaust gas adsorption tower 1, allowing the exhaust gas adsorption cotton 605 on both sides of the sliding sleeve 5 to alternately connect with the interior of the inlet pipe 3 and the outlet pipe 610, thus adsorbing and purifying the industrial exhaust gas. The exhaust gas adsorption cotton 605 on both sides of the sliding sleeve 5 is separated by a partition plate 604, forming independent spaces to prevent the industrial exhaust gas from flowing between them. This improves the post-treatment purification efficiency of industrial exhaust gas and reduces the space occupied by the equipment. By closing the outlet pipe 610, gas enters the sliding sleeve 5 through the connecting groove 608. This allows the clean gas to move from the other side, away from the exhaust gas adsorption cotton 605, carrying away impurities and foreign objects from inside the adsorption cotton, which are then discharged through the return pipe 706. This facilitates adsorption purification and clean regeneration of the exhaust gas using a single tower, reducing gas loss during regeneration.

[0029] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The regulating mechanism 6 includes a drive motor 601 bolted to one side of the surface of the exhaust gas adsorption tower 1. A fixed plate 612 is welded to the bottom of the sliding sleeve 5. A semi-circular bevel gear ring 602, which is fixedly sleeved with the sliding sleeve 5, is installed on the top of the fixed plate 612. A bevel gear 603, which meshes with the semi-circular bevel gear ring 602, is bolted to the output end of the drive motor 601. Both sides of the interior of the sliding sleeve 5 are filled with exhaust gas adsorption cotton 605. A spacer plate 604, which is welded to the sliding sleeve 5, is provided between the two exhaust gas adsorption cottons 605. An exhaust pipe 61 is fixedly connected through one side of the interior of the sealing pipe 2. A first solenoid valve 611 is bolted to the end of the outlet pipe 610 away from the sealing port 2. An outlet pipe hole 609 is fixedly connected to the surface of the end of the outlet pipe 610 inside the sealing port 2. An inlet pipe hole 607 is fixedly connected to the bottom end of the inlet pipe 3. Ventilation holes 606, communicating with the inlet pipe hole 607 and the outlet pipe hole 609 respectively, are opened at the top and bottom of the two exhaust gas adsorption cottons 605 on the inner wall of the sliding sleeve 5. A connecting groove 608 is opened inside the intermediate column 4, and the bottom of the inner cavity of the intermediate column 4 is connected to the outlet pipe 610 through the connecting groove 608. This allows the exhaust gas adsorption cottons 605 on both sides of the sliding sleeve 5 to alternately communicate with the interior of the inlet pipe 3 and the outlet pipe 610, thereby adsorbing and purifying industrial exhaust gas and improving the post-treatment purification efficiency of industrial exhaust gas.

[0030] refer to Figure 2 , Figure 3 , Figure 5 The cleaning mechanism 7 includes a sealing piston 703 that is slidably inserted into the middle column 4 near the end of the air outlet pipe 610. A lifting plate 702 is adhered to the top of the sealing piston 703. Return springs 701, which are fixedly connected to the middle column 4, are bolted to both sides of the bottom of the second solenoid valve 707. An air inlet hole 704 is provided at the top of the surface of the middle column 4 at the end of the air inlet pipe 3 away from the air inlet hole 607. The top of the connecting groove 608 connects to the sliding plate 703 through the air inlet hole 704 and the vent hole 606. The top of the inner cavity of the moving sleeve 5 is interconnected. A return air hole 705 is provided at the bottom of the surface of the intermediate column 4, at the end of the outlet pipe 610 away from the outlet hole 609. The interior of the sealing port 2 is interconnected with the ventilation hole 606 through the return air hole 705 and the bottom of the inner cavity of the sliding sleeve 5. A return air pipe 706 is fixedly connected to the bottom of the sealing port 2 away from the outlet pipe 610. A second solenoid valve 707 is bolted to the end of the return air pipe 706 away from the sealing port 2. This allows the clean gas to move within the tail gas adsorption cotton 605, carrying away impurities and foreign objects, facilitating adsorption, purification, and regeneration of the tail gas using a single tower, and reducing gas loss during regeneration.

[0031] refer to Figure 1 , Figure 2 , Figure 3 A heat-conducting ring sleeve 8, bolted to the exhaust gas adsorption tower 1, is slidably fitted onto the surface of the sliding sleeve 5. An electric heater 9, electrically connected to the heat-conducting ring sleeve 8, is bolted to one side of the exhaust gas adsorption tower 1. By turning on the electric heater 9, the heat-conducting ring sleeve 8 is heated, thereby raising the temperature of the exhaust gas adsorption cotton 605 inside the sliding sleeve 5. This allows the exhaust gas adsorption cotton 605 to perform high-temperature sterilization and disinfection of the passing exhaust gas. Simultaneously, it can also dry the exhaust gas adsorption cotton 605, preventing moisture in the exhaust gas from adsorbing onto its surface.

[0032] refer to Figure 1 , Figure 2 The top of the exhaust gas adsorption tower 1 is provided with a connecting pipe 10 that is fixedly connected to the inlet pipe 3. This facilitates the connection of industrial exhaust gas pipelines, allowing industrial exhaust gas to be transported into the exhaust gas adsorption tower 1 for purification treatment through the connecting pipe 10 and the inlet pipe 3.

[0033] refer to Figure 5 , Figure 6 A sealing ring 12, which mates with the vent hole 606, is bonded between the surface of the intermediate column 4 and the inner wall of the sliding sleeve 5. This improves the sealing performance at the vent hole connection and prevents industrial exhaust gas from leaking from the gap between the intermediate column 4 and the sliding sleeve 5.

[0034] refer to Figure 5 , Figure 6 The top and bottom sides of the inner cavity of the exhaust gas adsorption tower 1 are rotatably connected to the sliding sleeve 5, which is slidably connected to the supporting ball bearings 11. This reduces the friction of the sliding sleeve 5 when it rotates inside the exhaust gas adsorption tower 1 and improves rotational stability.

[0035] refer to Figure 2 , Figure 7 Limiting springs 14 are bolted to both sides of the surface of the intermediate column 4. A conical locking block 15 is fixedly connected to one end of the limiting spring 14 near the sliding sleeve 5. Conical grooves 13 are opened on both sides of the inner wall of the sliding sleeve 5, which slide into the conical locking block 15. By using the elastic force of the limiting spring 14 to push the conical locking block 15 into the conical groove 13, the sliding sleeve 5 can be limited and fixed, so that the sliding sleeve 5 will not shift after adjusting its position by rotating in both directions, thus improving the accuracy of the vent hole connection. At the same time, when the sliding sleeve 5 rotates, the inclined surfaces of the conical locking block 15 and the conical groove 13 fit together, so that the conical locking block 15 can automatically overcome the elastic force of the limiting spring 14 and retract into the intermediate column 4 under pressure.

[0036] refer to Figure 1 Each of the four corners of the bottom of the exhaust gas adsorption tower 1 is bolted with a support leg 16. This improves the stability of the exhaust gas adsorption tower 1 and facilitates the purification and treatment of industrial exhaust gases.

[0037] Brief description of the operation: First, industrial exhaust gas enters the exhaust gas adsorption tower 1 through the inlet pipe 3, and is then transported to the sliding sleeve 5 through the inlet pipe hole 607 and the vent hole 606. At this time, the first solenoid valve 611 is opened, allowing the industrial exhaust gas to be adsorbed and purified by the exhaust gas adsorption cotton 605, and then discharged from the exhaust pipe 610 through the outlet pipe hole 609 and the vent hole 606.

[0038] When the adsorption capacity of the exhaust gas adsorption cotton 605 on one side inside the sliding sleeve 5 decreases, the drive motor 601 is turned on to drive the bevel gear 603 to rotate. This causes the bevel gear 603 to mesh with the semi-circular bevel ring 602, which in turn drives the sliding sleeve 5 on top of the fixed disk 612 to rotate. Since the semi-circular bevel ring 602 is semi-circular, the semi-circular bevel ring 602 and the bevel gear 603 can only mesh with each other to drive the sliding sleeve 5 to rotate 180°. This moves the exhaust gas adsorption cotton 605 on the other side inside the sliding sleeve 5 to a position that connects with the air inlet hole 607 and the air outlet hole 609. This allows it to adsorb and purify industrial exhaust gases. If it is necessary to reset the exhaust gas adsorption cotton 605 on one side, simply turn on the drive motor 601 to drive the bevel gear 603 to rotate and mesh with the semi-circular bevel gear ring 602, thereby rotating the sliding sleeve 5 by 180°. The exhaust gas adsorption cotton 605 on both sides inside the sliding sleeve 5 is separated by the partition plate 604 to form an independent space, preventing the industrial exhaust gases from flowing between each other.

[0039] When the moved exhaust gas adsorption cotton 605 needs to be cleaned and regenerated, the first solenoid valve 611 is closed while the second solenoid valve 707 is opened. Since the purified gas cannot be discharged through the exhaust pipe 610, the spring force of the return spring 701 is overcome, pushing the sealing piston 703 out of the exhaust pipe 610. This causes the lifting plate 702 to slide upwards, allowing the interior of the exhaust pipe 610 to connect with the connecting groove 608. The purified gas can then enter the sliding sleeve 5 through the inlet hole 704 and the vent hole 606. The purified gas then blows out impurities and foreign objects from inside the exhaust gas adsorption cotton 605 through the exhaust hole 606 and the return hole 705, and is then carried to the sealed port 2. Finally, the gas is returned to the main industrial exhaust gas pipeline through the return pipe 706, allowing it to enter the exhaust gas adsorption tower 1 through the inlet pipe 3 for reprocessing.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
