Description

Technical Field

[0001] This invention belongs to the field of spray tower technology, specifically relating to a waste gas spray tower device for waste gas treatment. Background Technology

[0002] Spray towers are generally used for waste gas treatment. In some industrial production processes, a large amount of waste gas is discharged. In order to ensure that the waste gas meets the emission standards, spray towers are generally used to treat the waste gas.

[0003] When the spray tower is running, the waste gas containing pollutants enters from the bottom of the tower under the action of the fan. The spray system atomizes the absorbent liquid (such as water, alkaline or acidic solution) into fine droplets through the nozzles and sprays it onto the surface of the packing layer. The waste gas flows from bottom to top and comes into full contact with the liquid film on the surface of the packing. The pollutants are transferred into the liquid phase through physical absorption, dissolution or chemical reaction. The purified gas is discharged from the top of the tower.

[0004] However, when existing spray towers are in use, sticky particles in the exhaust gas easily adhere to the filter screen surface on the packing surface. Long-term accumulation causes blockage of the filter screen, affecting the gas treatment efficiency. In addition, the packing in the packing layer is usually fixed. When reacting with the exhaust gas, only the surface part of the packing can fully contact the spray, and cannot fully react with the exhaust gas. This reduces the quality of exhaust gas treatment, and the packing cannot be fully utilized, which easily leads to resource waste. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a waste gas spray tower device for waste gas treatment.

[0006] The technical solution adopted to solve the above technical problems is: a waste gas spray tower device for waste gas treatment, including a spray tower body, two sets of bearing plates are vertically arranged on the side wall of the spray tower body, each set of bearing plates has two plates, and they are symmetrically fixed on the front and rear inner walls of the spray tower body. Each set of bearing plates is provided with a rolling packing assembly that drives the packing to move. One side of the bearing plate is provided with a filter hole cleaning assembly that cleans the surface of the rolling packing assembly. The interior of the spray tower body is provided with a uniform spraying assembly that evenly sprays the rolling packing assembly.

[0007] The spray tower body has a water storage tank at its bottom interior. The water storage tank contains a stirring component for uniformly stirring the spray liquid. The uniform spraying component is connected to the water storage tank. The side wall of the spray tower body has an impurity recovery mechanism for collecting impurities cleaned by the filter hole cleaning component. The outer side wall of the spray tower body has a drive component for driving the rolling packing component, uniform spraying component, filter hole cleaning component, and stirring component.

[0008] Furthermore, the rolling packing assembly includes a cylinder frame and a drive rod rotatably connected to the side wall of the main body of the spray tower. One end of the drive rod located inside the tower is provided with a limiting protrusion. The outer side wall of the cylinder frame surrounds and fixes a filter cylinder. One end of the cylinder frame is provided with a limiting hole that matches the shape of the limiting protrusion. The other end of the cylinder frame is provided with a threaded hole. A cylinder cover is threadedly connected to the inner wall of the threaded hole. A handle is fixed to the outer surface of the cylinder cover. Several partitions are arranged at equal intervals along the rotation axis on the inner side wall of the cylinder frame. Several dispersion racks are arranged and fixed along the axis on the inner wall of the cylinder frame.

[0009] Through the above technical solution, the drive rod drives the cylinder frame to rotate, which in turn drives the partition and the dispersing frame to rotate, continuously dispersing and stirring the packing, increasing the contact area between the packing and the spray. This not only dynamically updates the contact area between the waste gas and the spray liquid, but also makes the liquid film distribution on the surface of the packing more uniform, greatly enhancing the gas-liquid mass transfer process. This not only improves the reaction efficiency, but also avoids the waste of packing due to insufficient reaction.

[0010] Furthermore, the top of each of the rear bearing plates is provided with a flow guiding slope, and the side wall of each bearing plate facing the filter cartridge is provided with a limiting arc surface. The surface of the limiting arc surface is in close contact with the outer surface of the filter cartridge. The side wall of the spray tower body is provided with a disassembly and assembly port corresponding to the position of the cartridge frame. The inner side wall of each disassembly and assembly port is rotatably connected with a sealing door.

[0011] Through the above technical solution, the limiting arc surface of the bearing plate serves as the limit and guide for the filter cartridge, bearing the weight of the rolling packing assembly and the packing while ensuring the stable rotation of the rolling packing assembly and ensuring that the packing is always in the best working condition; when the packing is replaced, the limiting of the rolling packing assembly can be released, simplifying the disassembly and assembly steps and improving work efficiency.

[0012] Furthermore, the uniform spraying assembly includes a circulating pump fixedly installed on the side wall of the spray tower body. The pump's inlet is connected to a water storage tank via a water pipe, and the pump's outlet is connected to a diverter pipe. Each diverter pipe's outlet is rotatably connected to a diverter via a rotary joint. Each rotary joint is fixed to the side wall of the spray tower body. Two diverters are located above two filter cartridges, and the other end of each diverter is rotatably connected to the side wall of the spray tower body. Several diverter pipe openings are spirally distributed along the axis of each diverter, and each diverter pipe opening is equipped with a self-rotating spray unit to achieve self-rotating spraying.

[0013] Furthermore, the self-rotating spray unit includes a second rotary joint threadedly connected to the diversion pipe port. The other end of the second rotary joint is threadedly connected to a multi-hole nozzle. Each nozzle of the multi-hole nozzle is equipped with an atomizing nozzle. A fixing frame is fixedly connected to the inner side wall of the multi-hole nozzle. An impeller is fixedly connected to the side of the fixing frame facing the second rotary joint. An annular protrusion is provided on the inner side wall of the multi-hole nozzle. A solid-liquid separation screen is engaged with the multi-hole nozzle through the annular protrusion. The side wall of the solid-liquid separation screen is provided with an elastic protrusion that limits the movement of the annular protrusion.

[0014] With the above technical solution, when spraying exhaust gas, the circulating pump draws spray liquid from the water storage tank through the water pipe, and accurately distributes it to each distributor through the diverter pipe, then to each diverter port, and finally to each multi-hole nozzle. The solid-liquid separation net intercepts particulate matter in the spray liquid to prevent nozzle clogging. At the same time, the water flow drives the multi-hole nozzle to rotate through the impeller and rotary joint. The atomizing nozzle atomizes the spray liquid, and the driving device synchronously drives the rod distributor to rotate, which in turn drives the spirally distributed multi-hole nozzle to revolve. This achieves multi-dimensional dynamic coverage of the filter cartridge surface by the spray liquid, eliminating the spray blind spots caused by traditional fixed nozzles, ensuring that the dynamic packing below can be fully and thoroughly wetted without dead angles, and maximizing the utilization of the packing surface area.

[0015] Furthermore, the filter cleaning assembly includes an installation groove on the rear side of the front support plate and a transmission rod that is rotatably connected to the side wall of the spray tower body. Two rotating shafts are rotatably connected to the upper and lower inner walls of the installation groove. Synchronous pulleys and bevel gears are fixed to the outer walls of the rotating shafts. A cleaning synchronous belt is connected between the two synchronous pulleys. Brush bristles are evenly distributed on the outer surface of the cleaning synchronous belt. The brush bristles are in contact with the outer surface of the filter cartridge. Each bevel gear is meshed with a second bevel gear. The second bevel gear is sleeved and fixed to the outer wall of the transmission rod. A protective cover is fixed to the top of the front support plate. The upper surface of the protective cover is set as a guide slope.

[0016] The above technical solution drives the transmission rod to rotate, which in turn drives the two rotating shafts and synchronous pulleys to rotate through the meshing of bevel gear one and bevel gear two. This, in turn, drives the cleaning synchronous belt to rotate. The bristles of the rotating cleaning synchronous belt are in continuous contact with the surface of the rotating filter cartridge, effectively and continuously scraping away sticky impurities, biofilms, or crystals attached to the filter holes and surface. The process does not require machine shutdown, fundamentally solving the industry problem of increased pressure drop and decreased processing efficiency caused by clogging of the packing layer, and ensuring the long-term continuous and stable operation of the equipment.

[0017] Furthermore, the stirring assembly includes a stirring shaft that is rotatably connected through the inner wall of the water storage tank. Two annular frames are sleeved and fixed on the outer wall of the stirring shaft. Several stirring plates are welded and fixed between the two annular frames along the axis. Several drainage grooves are equidistantly opened on the side wall of the stirring plates.

[0018] The above technical solution drives the stirring plate and the ring frame to rotate through the stirring shaft. With the help of the diversion groove on the stirring plate, the spray liquid in the water storage tank is continuously stirred. This can prevent the reagent from settling, ensure the uniform concentration of the spray liquid, and promote the uniform dispersion of soluble components in the waste gas in the liquid, thus maintaining a highly efficient chemical reaction environment.

[0019] Furthermore, the drive assembly includes a motor fixed to the outer wall of the spray tower body, a multi-groove pulley fixed to the lower drive rod, a first pulley fixed to the upper drive rod, a second pulley fixed to the distributor, two third pulleys fixed to the lower transmission rod, a fourth pulley fixed to the upper transmission rod, and a fifth pulley fixed to the stirring shaft. The multi-groove pulley is connected to the first, second, third, and fifth pulleys via belts, and the third pulley is connected to the fourth pulley via belts.

[0020] Through the above technical solution, the drive component uses a single motor in conjunction with multi-stage belt transmission to synchronously drive the packing roll, sprayer rotation, cleaning brush operation, and agitator operation. The highly integrated design simplifies the equipment structure, reduces manufacturing costs and failure rate, while ensuring the coordination of the actions between various functional components and achieving higher operating efficiency.

[0021] Furthermore, the impurity recovery mechanism includes recovery ports opened on the side wall of the main body of the spray tower. The recovery ports are all corresponding to the positions of the cleaning synchronous belts. A recovery box is installed through the inner wall of the recovery port. A drain port is opened on the rear side of the recovery box. The drain port is in contact with the outer surface of the filter cartridge. A suction groove is opened on the side wall of the recovery box outside the tower. A collection drawer is slidably connected to the inner wall of the suction groove. A filter screen is provided on the side wall of the collection drawer facing the drain port. The collection drawers are all located diagonally below the adjacent cleaning synchronous belts.

[0022] Through the above technical solution, the scraped impurities fall into the recovery box through the recovery port. The collection tray with filter screen achieves preliminary solid-liquid separation, and the liquid flows back into the tower, reducing secondary pollution. The drain port is in close contact with the outer surface of the filter cartridge, and the filtered spray liquid can directly enter the filter cartridge to react with the packing material. This not only indirectly improves the reaction efficiency, but also avoids the reaction leakage caused by the waste gas directly passing through the drain port.

[0023] Furthermore, an air inlet is provided on the bottom side wall of the spray tower body, located between the lower rolling packing assembly and the water storage tank. A fan is installed inside the air inlet. An air outlet is provided on the top of the spray tower body. A feed pipe and a drain pipe are connected through the side wall block of the water storage tank. A cap is threaded onto the inlet of the feed pipe. A water valve is installed inside the drain pipe. Two observation ports are provided on the front side wall of the spray tower body, each corresponding to the position of the distributor. An observation window is rotatably connected to one side inner wall of each observation port.

[0024] The above technical solution allows for easy replenishment of the spray liquid via the feed pipe, and the cap seals the pipe opening to prevent exhaust gas leakage. The drain pipe controls the discharge of the spray liquid via a water valve. The observation window not only facilitates observation of the tower's operation, but also allows for maintenance when the uniform spraying components malfunction.

[0025] The beneficial effects of the present invention are as follows: (1) By setting the rolling packing assembly, the driving device drives the rolling packing assembly to rotate, continuously dispersing and stirring the packing inside, increasing the contact area between the packing and the spray, not only dynamically updating the contact area between the exhaust gas and the spray liquid, avoiding the “channeling” and “short circuit” phenomena that are easy to occur in traditional fixed packing, but also making the liquid film distribution on the surface of the packing more uniform, greatly strengthening the gas-liquid mass transfer process, not only improving the reaction efficiency, but also avoiding the waste of packing due to insufficient reaction;

[0026] (2) By setting uniform spray components, the spray liquid can dynamically cover the surface of the filter cartridge in multiple dimensions, eliminating the spray blind zone caused by traditional fixed nozzles, ensuring that the dynamic packing below can be fully and without dead angles, and maximizing the use of the packing surface area.

[0027] (3) Through the filter hole cleaning component and impurity recovery mechanism, the rotating rolling packing component is coordinated with the rotating cleaning synchronous belt. Its bristles are in continuous contact with the rotating filter cartridge surface, and it can effectively and continuously scrape off the sticky impurities, biofilm or crystals attached to the filter hole and surface. The process does not require stopping the machine, which solves the industry problem of increased pressure drop and decreased processing efficiency caused by the blockage of the packing layer. The impurity recovery mechanism collects the impurities scraped off by the filter hole cleaning component, realizes the initial separation of solid and liquid, and the filtered liquid directly enters the filter cartridge to react with the packing. This not only indirectly improves the reaction efficiency, but also avoids secondary pollution. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] like Figures 1-11 As shown, an exhaust gas spray tower device for exhaust gas treatment in this embodiment includes a spray tower body 1. Two sets of bearing plates 4 are vertically arranged on the side wall of the spray tower body 1. Each set of bearing plates 4 has two plates, which are symmetrically fixed on the front and rear inner walls of the spray tower body 1. Each set of bearing plates 4 is provided with a rolling packing assembly 5 that drives the packing to move. One side of the bearing plate 4 is provided with a filter hole cleaning assembly 7 that cleans the surface of the rolling packing assembly 5. The interior of the spray tower body 1 is provided with a uniform spraying assembly 6 that uniformly sprays the rolling packing assembly 5.

[0042] The spray tower body 1 has a water storage tank 104 at the bottom of its interior. The water storage tank 104 is equipped with a stirring component 8 for uniformly stirring the spray liquid. The uniform spraying component 6 is connected to the water storage tank 104. The side wall of the spray tower body 1 is equipped with an impurity recovery mechanism 16 for collecting impurities cleaned by the filter hole cleaning component 7. The outer side wall of the spray tower body 1 is equipped with a drive component 9 for driving the rolling packing component 5, the uniform spraying component 6, the filter hole cleaning component 7, and the stirring component 8.

[0043] The rolling packing assembly 5 includes a cylinder frame 501 and a drive rod 503 rotatably connected to the side wall of the spray tower body 1. One end of the drive rod 503 located inside the tower has a limiting protrusion 504. A filter cartridge 502 is fixedly surrounded by the outer wall of the cylinder frame 501. One end of the cylinder frame 501 has a limiting hole 505 that matches the shape of the limiting protrusion 504. The other end of the cylinder frame 501 has a threaded hole 506. A cylinder cover 507 is threaded onto the inner wall of the threaded hole 506. A handle 508 is fixedly attached to the outer surface of the cylinder cover 507. Several partitions 509 are equidistantly arranged along the rotation axis on the inner wall of the cylinder frame 501. Several dispersion racks 510 are arranged and fixedly attached along the axis on the inner wall of the cylinder frame 501. In use, the rolling packing assembly 5 is filled with packing material into the filter cartridge 502. The cylinder cover 507 is screwed into the threaded hole 506 through the handle 508 to seal the packing material. For waste gas treatment, the waste... Gas passes upward through the filter cartridge 502 and the packing material. While processing the gas, the drive rod 503 drives the cylinder frame 501 to rotate, which in turn drives the baffle 509 and the dispersing frame 510 to rotate, continuously dispersing and stirring the packing material. This increases the contact area between the packing material and the spray, not only dynamically updating the contact area between the waste gas and the spray liquid, avoiding the "channeling" and "short-circuiting" phenomena that are prone to occur in traditional fixed packing materials, but also making the liquid film distribution on the surface of the packing material more uniform. This greatly enhances the gas-liquid mass transfer process, improving reaction efficiency and preventing waste of packing material due to incomplete reaction. The limiting protrusion on the drive rod 503 and the limiting hole 505 on the cylinder frame 501 limit each other, ensuring that the drive rod 503 drives the cylinder frame 501 to rotate normally, while facilitating the disassembly and replacement of the packing material in the rolling packing assembly 5. Applicable packing materials can be replaced according to the working scenario, making it suitable for complex waste gas treatment environments.

[0044] The top of each of the rear support plates 4 is provided with a guide slope 401, and the side wall of the support plate 4 facing the filter cartridge 502 is provided with a limiting arc surface 402. The surface of the limiting arc surface 402 is in close contact with the outer surface of the filter cartridge 502. The side wall of the spray tower body 1 is provided with a disassembly port 103 corresponding to the position of the cartridge 501. The inner side wall of the disassembly port 103 is rotatably connected with a sealing door 11. The guide slope 401 is provided to direct the sprayed water flow to the filter cartridge 502 to avoid water stagnation affecting the reaction. The limiting arc surface 401 of the support plate 4 Surface 402 serves as a limit and guide for filter cartridge 502, bearing the weight of the rolling packing assembly 5 and the packing while ensuring the stable rotation of the rolling packing assembly 5 and guaranteeing that the packing is always in the best working condition. When replacing the packing, opening the sealing door 11 exposes the disassembly port 103, which releases the limit on the rolling packing assembly 5. The rolling packing assembly 5 can be directly slid out using the handle 508, and the packing can be replaced by rotating and opening the cartridge cover 507. The structure is simple, simplifying the disassembly and assembly steps and improving work efficiency.

[0045] The uniform spraying assembly 6 includes a circulating pump 601 fixedly installed on the side wall of the spray tower body 1. The water inlet of the circulating pump 601 is connected to the water storage tank 104 through a water pipe 15. The water outlet of the circulating pump 601 is connected to a diverter pipe 602. Each diverter pipe 602 has a diverter 603 rotatably connected to its diverter through a rotary joint 604. The rotary joint 604 is fixed to the side wall of the spray tower body 1. The two diverters 603 are located above the two filter cartridges 502 respectively. The other end of each diverter 603 is rotatably connected to the side wall of the spray tower body 1. Several diverter pipe ports 605 are spirally distributed along the axis of the diverter 603. Each diverter pipe port 605 is equipped with a self-rotating spray unit to achieve self-rotating spraying. 606, the self-rotating spray unit 606 includes a rotary joint 6061 threadedly connected to the diversion pipe port 605, the other end of the rotary joint 6061 is threadedly connected to a multi-hole nozzle 6062, the nozzles of the multi-hole nozzle 6062 are all equipped with atomizing nozzles 6068, the inner side wall of the multi-hole nozzle 6062 is fixedly connected to a fixing frame 6063, the side of the fixing frame 6063 facing the rotary joint 6061 is fixedly connected to an impeller 6064, the inner side wall of the multi-hole nozzle 6062 is provided with an annular protrusion 6067, a solid-liquid separation net 6065 is engaged and connected inside the multi-hole nozzle 6062 through the annular protrusion 6067, the side wall of the solid-liquid separation net 6065 is provided with an elastic protrusion 6066 that is limited and matched with the annular protrusion 6067;

[0046] When spraying exhaust gas, the circulating pump 601 draws spray liquid from the water storage tank 104 through the water pipe 15, and accurately distributes it to each distributor 603 through the distribution pipe 602, then to each distribution pipe opening 605, and finally to each multi-hole nozzle 6062. During this distribution, the solid-liquid separation net 6065 intercepts particulate matter in the spray liquid, preventing nozzle clogging and ensuring long-term stable operation. Simultaneously, the water flow drives the multi-hole nozzle 6062 to rotate through the impeller 6064 and rotary joint 6061. The atomizing nozzle 6068 atomizes the spray liquid, and the driving component 9 synchronously drives the distributor 603 to rotate, thereby causing the spirally distributed multi-hole nozzle 6062 to revolve, achieving multi-dimensional dynamic coverage of the spray liquid. The surface of the filter cartridge 502 eliminates the spray blind spots caused by traditional fixed nozzles, ensuring that the dynamic packing below can be fully and thoroughly wetted, maximizing the utilization of the packing surface area. After impurities are filtered by the filter cartridge 502, the filtered spray liquid flows back into the water storage tank 104, forming a closed-loop process, ensuring a continuous supply of spray liquid, improving the utilization rate of spray liquid, and avoiding resource waste. When cleaning the particles intercepted in the solid-liquid separation net 6065, the multi-hole nozzle 6062 is rotated off, and the solid-liquid separation net 6065 is pulled outward with force. The elastic protrusion 6066 disengages from the limit of the annular protrusion 6067, thus completing the disassembly of the solid-liquid separation net 6065, allowing for particle processing and facilitating maintenance.

[0047] The filter cleaning assembly 7 includes a mounting groove 701 located on the rear side of the front support plate 4, and a transmission rod 707 rotatably connected to the side wall of the spray tower body 1. Two rotating shafts 702 are rotatably connected to the upper and lower inner walls of the mounting groove 701. Synchronous pulleys 703 and bevel gears 704 are fixedly connected to the outer walls of each rotating shaft 702. A cleaning timing belt 705 is connected between the two synchronous pulleys 703. Brush bristles 706 are evenly distributed on the outer surface of the cleaning timing belt 705, and these bristles 706 contact the outer surface of the filter cartridge 502. Each bevel gear 704 is meshed with a second bevel gear 708, which is sleeved and fixed to the outer wall of the transmission rod 707. A protective cover 709 is fixedly attached to the top of the front support plate 4. The upper surface of the protective cover 709 is designed as a guide slope 710. While the drive assembly 9 drives the filter cartridge 502 to roll, it also drives the transmission rod 707 to rotate. The rotation is achieved through the bevel gears 704 and 705. The meshing transmission of 08 drives the two rotating shafts 702 and the synchronous pulley 703 to rotate, which in turn drives the cleaning synchronous belt 705 to rotate. The rotating cleaning synchronous belt 705 has its bristles 706 in continuous contact with the surface of the filter cartridge 502, effectively and continuously scraping away sticky impurities, biofilms or crystals attached to the filter holes and surface. The process does not require machine shutdown, realizing online automatic cleaning of the packing. This fundamentally solves the industry problem of increased pressure drop and decreased processing efficiency caused by packing layer blockage, ensuring long-term continuous and stable operation of the equipment. In addition, the longitudinally rotating filter cartridge 502 is in contact with the transversely rotating cleaning synchronous belt 705, which increases the friction of continuous scraping and further improves the scraping effect. The protective cover 709 protects the gears to prevent impurities or particles from continuously accumulating on the gears and affecting their normal operation. The set guide slope 710 directs the sprayed water flow to the filter cartridge 502 to prevent water stagnation from affecting the reaction.

[0048] The stirring assembly 8 includes a stirring shaft 801 that is rotatably connected through the inner wall of the water storage tank 104. Two annular frames 802 are sleeved and fixed on the outer wall of the stirring shaft 801. Several stirring plates 803 are welded and fixed between the two annular frames 802 along the axis. Several drainage grooves 804 are equidistantly opened on the side wall of the stirring plates 803. The stirring shaft 801 drives the stirring plates 803 and the annular frames 802 to rotate. In conjunction with the drainage grooves 804 on the stirring plates 803, the spray liquid in the water storage tank 104 is continuously stirred. This can prevent the reagent from settling, ensure the uniform concentration of the spray liquid, and promote the uniform dispersion of soluble components in the waste gas in the liquid, thus maintaining a highly efficient chemical reaction environment.

[0049] Drive assembly 9 includes a motor 901 fixed to the outer wall of the spray tower body 1, a multi-groove pulley 902 sleeved and fixed to the lower drive rod 503, a first pulley 903 sleeved and fixed to the upper drive rod 503, a second pulley 904 sleeved and fixed to the distributor 603, two third pulleys 905 sleeved and fixed to the lower transmission rod 707, a fourth pulley 906 sleeved and fixed to the upper transmission rod 707, and a fifth pulley 907 sleeved and fixed to the stirring shaft 801. The multi-groove pulley 902 is connected to a belt. It is connected to pulley 1 903, pulley 2 904, pulley 3 905, and pulley 5 907. Another pulley 3 905 is connected to pulley 4 906 via a belt. The drive component 9 is driven by a motor 901 in conjunction with multi-stage belt drive, which synchronously drives the packing to roll, the sprayer to rotate, the cleaning brush to run, and the agitator to work. The highly integrated design simplifies the equipment structure, reduces manufacturing costs and failure rate, and at the same time ensures the coordination of the actions between the functional components, resulting in higher operating efficiency.

[0050] The impurity recovery mechanism 16 includes recovery ports 1601 located on the side wall of the main body 1 of the spray tower. Each recovery port 1601 corresponds to a position on the cleaning synchronous belt 705. A recovery box 1602 is installed through the inner wall of each recovery port 1601. A drain port 1603 is located on the rear side of the recovery box 1602 and is in contact with the outer surface of the filter cartridge 502. A suction groove 1604 is located on the side wall of the recovery box 1602 outside the tower. A collection tray 1605 is slidably connected to the inner wall of the suction groove 1604. A filter screen 1606 is provided on the side wall of the collection tray 1605 facing the drain port 1603. Each collection tray 1605 is located diagonally below the adjacent cleaning synchronous belt 705. The impurity recovery mechanism 16 filters... Impurities scraped off by the hole cleaning component 7 are collected and fall into the recovery box 1602 through the recovery port 1601. The collection tray 1605 with filter screen 1606 achieves preliminary solid-liquid separation. The liquid flows back into the tower, while the solid impurities are intercepted, realizing the fixed-point and centralized collection of waste residue and reducing secondary pollution. The drain port 1603 is in contact with the outer surface of the filter cartridge 502, and the filtered spray liquid can directly enter the filter cartridge 502 to react with the packing. This not only indirectly improves the reaction efficiency but also avoids the reaction leakage caused by the waste gas directly passing through the drain port 1603. When cleaning impurities, the collection tray 1605 can be directly pulled out from the extraction groove 1604, reducing the frequency and intensity of manual maintenance.

[0051] An air inlet 101 is provided on the bottom side wall of the spray tower body 1. The air inlet 101 is located between the rolling packing assembly 5 and the water storage tank 104. A fan 2 is installed inside the air inlet 101. An air outlet 3 is provided on the top of the spray tower body 1. A feed pipe 12 and a drain pipe 14 are connected through the side wall of the water storage tank 104. A cap 13 is threaded onto the inlet of the feed pipe 12. A water valve is installed inside the drain pipe 14. Two observation ports 102 are provided on the front side wall of the spray tower body 1. The observation ports 102 correspond to the positions of the distributor 603. Inside one side of the observation port 102... The wall is rotatably connected to an observation window 10. The fan 2 draws the exhaust gas into the tower from the bottom air inlet 101, and it passes through two stages of rotating packing layers and the spray zone in sequence, making full counter-current contact with the spray liquid. The treated gas is discharged from the air outlet 3. The feed pipe 12 facilitates the replenishment of the spray liquid, and the cover 13 seals the pipe opening to prevent exhaust gas leakage. The drain pipe 14 discharges the spray liquid through a water valve ratio control. The observation window 10 not only facilitates real-time observation of the spray status and the working condition of the packing, but also allows for maintenance when the uniform spraying component 6 malfunctions.

[0052] The working principle of this embodiment is as follows: When in use, the fan 2 draws the exhaust gas from the bottom air inlet 101 into the tower, and passes through the two-stage rotating packing layer and the spray zone in sequence. At the same time, the motor 901 and the circulating pump 601 are started. The motor 901 drives the rolling packing assembly 5, the uniform spraying assembly 6, the filter cleaning assembly 7, and the stirring assembly 8 to run synchronously through belt drive.

[0053] When spraying exhaust gas, the circulating pump 601 draws spray liquid from the water storage tank 104 through the water pipe 15, and accurately distributes it to each distributor 603 through the diversion pipe 602, then to each diversion pipe port 605, and then to each multi-hole nozzle 6062. When the solid-liquid separation net 6065 intercepts particulate matter in the spray liquid, the water flow drives the multi-hole nozzle 6062 to rotate through the impeller 6064 and the rotary joint 6061. The atomizing nozzle 6068 atomizes the spray liquid. The driving component 9 synchronously drives the distributor 603 to rotate, which in turn drives the spirally distributed multi-hole nozzle 6062 to revolve. This achieves multi-dimensional dynamic coverage of the filter cartridge 502 surface by the spray liquid, so that the packing can be fully and without dead corners wetted, maximizing the utilization of the packing surface area.

[0054] When reacting synergistically with the spray liquid, the drive rod 503 drives the cylinder frame 501 to rotate, which in turn drives the partition plate 509 and the dispersion frame 510 to rotate, continuously dispersing and stirring the packing, increasing the contact area between the packing and the spray. This not only dynamically updates the contact area between the exhaust gas and the spray liquid, but also makes the liquid film distribution on the surface of the packing more uniform, greatly enhancing the gas-liquid mass transfer process.

[0055] At the same time, the drive transmission rod 707 rotates, and through the meshing transmission of bevel gear 1 704 and bevel gear 2 708, it drives the two rotating shafts 702 and the synchronous pulley 703 to rotate, which in turn drives the cleaning synchronous belt 705 to rotate. The rotating cleaning synchronous belt 705 has its bristles 706 in continuous contact with the surface of the filter cartridge 502, and can effectively and continuously scrape off the sticky impurities, biofilm or crystals attached to the filter holes and surface, avoiding the pressure drop increase caused by the packing layer being blocked.

[0056] The scraped impurities fall into the recovery box 1602 through the recovery port 1601. The collection tray 1605 with the filter screen 1606 achieves preliminary solid-liquid separation. The liquid flows back into the tower, realizing the fixed-point and centralized collection of waste residue, reducing secondary pollution. Moreover, the filtered spray liquid can directly enter the filter cartridge 502 to react with the packing, which not only indirectly improves the reaction efficiency, but also avoids the reaction leakage caused by the waste gas directly passing through the discharge port 1603.

[0057] After the impurities are filtered by the filter cartridge 502, the filtered spray liquid flows back into the water storage tank 104, forming a closed loop process to ensure a continuous supply of spray liquid. The stirring shaft 801 drives the stirring plate 803 and the ring frame 802 to rotate, and in conjunction with the diversion groove 804 on the stirring plate 803, the spray liquid in the water storage tank 104 is continuously stirred. This can prevent the reagent from settling, ensure the uniform concentration of the spray liquid, and promote the uniform dispersion of soluble components in the waste gas in the liquid, thus maintaining a highly efficient chemical reaction environment.

[0058] The treated gas is discharged through outlet 3. This equipment is suitable for highly complex industrial waste gas treatment scenarios and achieves a balance of high efficiency, self-sufficiency, and economy.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
