Technical Field
[0001] This utility model relates to the technical field of exhaust gas treatment devices, and in particular to an exhaust gas treatment device for rust remover production. Background Technology
[0002] Rust removers generate exhaust gases during the raw material processing, reaction synthesis, and post-processing stages. The composition of the exhaust gases from rust remover production is directly related to the type of rust remover used, and mainly contains acid mist, volatile organic compounds (VOCs), alkaline gases, and a small amount of dust.
[0003] Rust remover production commonly uses acidic raw materials such as hydrochloric acid, phosphoric acid, and citric acid, which produce acidic exhaust gases such as hydrogen chloride and sulfur dioxide. Direct emission of these gases can lead to acid rain, polluting the atmosphere and water bodies. Some exhaust gases are toxic or flammable and explosive. Accumulation to a certain concentration may cause poisoning of personnel or explosion and combustion upon contact with an open flame, threatening the safety of the factory area. Utility Model Content

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0018] Example 1: Refer to Figures 1-5 As shown: A rust remover production exhaust gas treatment device includes a frame 4. A cartridge dust collector 5 is fixedly connected to the top of the frame 4. A purification mechanism is provided on one side of the cartridge dust collector 5. The purification mechanism includes a spray tower 6, a spray pipe 9, and an adsorption element 12. The adsorption element 12 is inserted into the top of the inner cavity of the spray tower 6. An adsorption plate 18 is fixedly connected to the inner wall of the adsorption element 12, and a through hole is opened at the bottom of the adsorption element 12. A spray plate 14 is fixedly connected to the inner circumference of the spray tower 6. A spray nozzle is installed at the bottom of the spray plate 14. A branch pipe 1 is fixedly connected to one side of the spray plate 14. 6. One end of the branch pipe 16 passes through the side wall of the spray tower 6 and is fixedly connected to the spray pipe 9. The end of the spray pipe 9 is fixedly connected to the water pump 10. The inlet of the water pump 10 is fixedly connected to the storage tank 11. The bottom of the storage tank 11 is connected to the spray tower 6 by bolts. The top of the spray tower 6 is fixedly connected to the guide ring 15. The guide ring 15 is inserted through the plug rod 17. The top of the plug rod 17 is fixedly connected to the adsorption element 12. The bottom of the plug rod 17 is engaged with two semi-circular limiting rings 13. The inner walls of the two limiting rings 13 are engaged with the spray tower 6.
[0019] The spray tower 6 serves as the core carrier of the purification mechanism, providing a closed and independent space for spray purification and adsorption purification. This ensures that the exhaust gas flows along a preset path within the tower, fully contacting the spray liquid and adsorption plate 18 to enhance the purification effect. Connecting the water pump 10 and branch pipe 16 ensures a stable delivery of the purified liquid from the storage tank 11 to the spray plate 14, providing liquid transport assurance for spray purification. The spray plate 14, fixed to the inner circumference of the spray tower 6, can evenly distribute the purified liquid delivered by the branch pipe 16 to the bottom nozzles. The nozzles atomize the liquid or spray it out in a columnar shape, increasing the contact area between the liquid and the exhaust gas and improving the spray purification effect. To improve efficiency, the adsorption plate 18 fixed inside the adsorption component 12 can perform secondary purification on the exhaust gas after spraying, enhancing the adsorption capacity for harmful impurities. The through-hole design at the bottom does not obstruct the flow of exhaust gas, but allows the exhaust gas to fully contact the adsorption plate 18. The guide ring 15 is fixed to the top of the spray tower 6, which plays a guiding and positioning role in the installation of the plug-in rod 17, ensuring that the plug-in rod 17 can be accurately inserted into the preset position, which facilitates the installation and disassembly of the adsorption component 12. The limiting ring 13 achieves the limiting and fixing of the plug-in rod 17 through a snap-fit method, which does not require complex bolt connections, making disassembly and assembly convenient, while ensuring the stability of the plug-in rod 17 after installation.
[0020] Example 2: Figure 1 and Figure 2 As shown, an axial flow fan 8 is fixedly connected to the outer ring of the spray tower 6. A guide pipe 7 is fixedly connected to one end of the axial flow fan 8. A one-way valve is installed at the end of the guide pipe 7. The guide pipe 7 is fixedly connected to the cartridge dust collector 5. An auxiliary cover is fixedly connected to one side of the cartridge dust collector 5. An exhaust pipe 1 is fixedly connected to one side of the auxiliary cover. A cyclone dust collector 2 is fixedly connected to the bottom of the exhaust pipe 1. A frame 3 is fixedly connected to the bottom of the cyclone dust collector 2. A reinforcing rod 19 is fixedly connected to one side of the frame 3. The reinforcing rod 19 is connected to the frame 4 by bolts.
[0021] An axial flow fan 8 is fixedly connected between the outer ring of the spray tower 6 and the guide pipe 7. It generates negative pressure to power the flow of exhaust gas, accelerating the delivery of exhaust gas from the cartridge dust collector 5 to the spray tower 6, thereby improving the overall rate of exhaust gas treatment. The guide pipe 7 provides a directional delivery channel for the exhaust gas, ensuring that the exhaust gas can accurately enter the axial flow fan 8 from the cartridge dust collector 5, avoiding exhaust gas leakage or diffusion. The one-way valve effectively prevents the purified liquid or purified gas in the spray tower 6 from flowing back to the cartridge dust collector 5, avoiding contamination of the treated exhaust gas or damage to the cartridge dust collector 5. The exhaust pipe 1 uses the principle of centrifugal force to perform preliminary purification of the exhaust gas, quickly separating large particulate impurities, reducing the processing pressure of the cartridge dust collector 5, and improving the overall processing efficiency. The cartridge dust collector 5 receives the exhaust gas that has been preliminarily treated by the cyclone dust collector 2 and performs secondary dust removal to further remove fine particulate impurities in the exhaust gas, providing cleaner exhaust gas for subsequent spray purification and improving the final purification effect.
[0022] The operating method and working principle of this device are as follows: First, connect the air inlet of exhaust pipe 1 to the exhaust gas end of the rust remover production, allowing the exhaust gas to smoothly enter exhaust pipe 1. After preliminary dust removal, the gas passes through exhaust pipe 1 and the auxiliary hood into cartridge dust collector 5 for secondary dust removal. The gas after secondary dust removal is discharged through guide pipe 7. Axial flow fan 8 accelerates the gas flow, sending the gas into spray tower 6. An external controller controls water pump 10 to operate, drawing out acidic or alkaline liquids from storage tank 11 and discharging them through spray pipe 9 and... Branch pipe 16 is fed into spray plate 14 and discharged through nozzle at the bottom of spray plate 14 to achieve spraying. The acid-base neutralization reaction is used to remove droplets. After spraying, the gas continues to rise and is adsorbed by the adsorption plate 18 with activated carbon inside the adsorption element 12 and discharged through the adsorption element 12. When it is necessary to disassemble and replace the adsorption element 12, the two limiting rings 13 can be moved away from the spray tower 6 to separate the limiting rings 13 from the spray tower 6 and the plug rod 17. At this time, the adsorption element 12 is moved upward and the plug rod 17 is separated from the guide ring 15, so that the adsorption element 12 and the adsorption plate 18 can be taken out together.
[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
