[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-5 This utility model provides the following two technical solutions: First embodiment: A copper strip pickling waste gas treatment device, comprising: Pickling box 1 is used to remove impurities from the surface of copper strip; Waste gas treatment box 2 is located at the right end of pickling box 1. Waste gas treatment box 2 is used to purify the waste gas discharged from pickling box 1. A first connecting pipe 3 is installed between pickling box 1 and waste gas treatment box 2. The spray assembly 4 is connected to the lower end of the exhaust gas treatment box 2 through the second connecting pipe 5. The spray assembly 4 includes a water collection tank 41, which is located at the rear end of the exhaust gas treatment box 2. The water collection tank 41 is connected to the lower end of the exhaust gas treatment box 2 through the second connecting pipe 5. A spray head 42 is fixedly installed on the inner top of the exhaust gas treatment box 2. A spray pipe 43 is installed between the water collection tank 41 and the spray head 42. A water pump 44 is fixedly installed on the spray pipe 43. The spray assembly 4 is used to spray the reactant into the exhaust gas treatment box 2 in the form of spraying. The filter assembly 6 is installed inside the exhaust gas treatment box 2 and at the port of the second connecting pipe 5. The filter assembly 6 includes a filter plate 61, which is located at the port of the second connecting pipe 5. The filter plate 61 is annular in shape and has a mounting plate 62 fixedly installed on it. The filter plate 61 has a plurality of centrally symmetrically distributed filter holes 63. A motor 64 is fixedly installed on the outer wall of the exhaust gas treatment box 2. The output end of the motor 64 passes through the exhaust gas treatment box 2 and is fixedly connected to the mounting plate 62. The filter assembly 6 is used to filter impurities in the reactant inside the exhaust gas treatment box 2 to prevent impurities from flowing back into the spray assembly 4. The cleaning component 7 includes a high-pressure vacuum cleaner 71, which is fixedly installed on the upper part of the outer wall of the exhaust gas treatment box 2. The output end of the high-pressure vacuum cleaner 71 passes through the exhaust gas treatment box 2 and contacts the filter plate 61. A cleaning roller 72 is rotatably installed on the inner wall of the exhaust gas treatment box 2. Multiple through-hole cones 73 are evenly installed on the cleaning roller 72 in a centrally symmetrical distribution. The shape and size of the through-hole cones 73 match the filter holes 63. The cleaning component 7 is used to clean the filter component 6.

[0022] In the pickling tank 1, copper strips are treated with an acidic solution to remove surface oxide scale, oil, and other impurities. This process generates waste gas containing acidic gases such as hydrogen chloride and sulfuric acid mist. The waste gas enters the waste gas treatment tank 2 from the pickling tank 1 through the first connecting pipe 3. The reactant in the water collection tank 41 is driven by the water pump 44 and sprayed out from the spray head 42 through the spray pipe 43, forming a mist of droplets. The mist of reactant comes into full contact with the waste gas in the waste gas treatment tank 2, and the acidic gases are removed through an acid-base neutralization reaction. The filter plate 61 of the filter assembly 6 is installed at the port of the second connecting pipe 5. When the sprayed... When the reaction liquid is refluxed, the filter hole 63 can intercept solid impurities in the solution. The filter plate 61 is rotated by the motor 64, so that the filter hole 63 located at the port of the second connecting pipe 5 is always unobstructed. The filter hole 63 blocked on the filter plate 61 is rotated by the motor 64 to the cleaning component 7. The high-pressure vacuum cleaner 71 adsorbs the impurities on the surface of the filter plate 61 through negative pressure. At the same time, the through hole cone 73 on the cleaning roller 72 is inserted into the hole when it rotates, and the residual impurities in the hole are removed by mechanical friction, ensuring that the filter hole 63 is unobstructed and preventing the accumulation of impurities from affecting the filtration effect.

[0023] In this embodiment, the filter component 6 is designed so that the solid substances produced after the reaction will not enter the spray component 4 with the backflow of the reactant, thereby avoiding the clogging of the spray component 4; the spray component 4 is designed to prevent the filter holes 63 from being clogged due to the accumulation of impurities, ensuring long-term continuous operation of the equipment, and the filtered reaction liquid can be returned to the spray component 4 for reuse, reducing reagent consumption and lowering operating costs.

[0024] The second implementation method differs from the first implementation method in that an air purifier 8 is installed at the right end of the exhaust gas treatment box 2, and a third connecting pipe 9 is installed between the exhaust gas treatment box 2 and the air purifier 8.

[0025] The third connecting pipe 9 has a square cross-section and multiple mounting holes 10 are provided on it. Mounting components 11 are slidably installed at the mounting holes 10, and an adsorption layer 12 is movably installed on the mounting components 11.

[0026] The third connecting pipe 9 serves as a transmission channel between the exhaust gas treatment box 2 and the air purifier 8. Multiple mounting holes 10 are evenly distributed on the third connecting pipe 9, and the mounting parts 11 can slide flexibly at the mounting holes 10, facilitating the installation, disassembly, and replacement of the adsorption layer 12. The adsorption layer 12 is made of materials with strong adsorption capacity, such as activated carbon and molecular sieves, which can effectively adsorb residual acidic gas molecules, organic pollutants, and fine particulate matter in the exhaust gas. When the exhaust gas enters the third connecting pipe 9 from the exhaust gas treatment box 2, the pollutants come into full contact with the adsorption layer 12 during the flow process and are intercepted and removed through physical adsorption and chemical adsorption, further reducing the concentration of pollutants in the exhaust gas. The air purifier 8 receives the exhaust gas after preliminary purification by the adsorption layer 12 through the third connecting pipe 9 and uses its own filtration, catalytic oxidation, and other technologies for deep treatment to ensure that the final exhaust gas meets higher air quality standards.

[0027] In this embodiment, by providing mounting holes 10 and mounting components 11, users can flexibly replace adsorption layers 12 with different adsorption capacities according to the degree of waste gas pollution and treatment needs, thereby enhancing the adaptability of the device to different operating conditions. In addition, when the adsorption layer 12 reaches saturation or fails, it can be quickly replaced without large-scale disassembly of the entire device, reducing maintenance difficulty and time costs, and ensuring continuous and stable operation of the device.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During use, the copper strip undergoes surface impurity removal in an acidic solution. The resulting waste gas, containing acidic gases such as hydrogen chloride and sulfuric acid mist, automatically flows into the waste gas treatment box 2 through the first connecting pipe 3. The water pump 44 is activated, and the reactant in the water collection tank 41 is sprayed from the spray head 42 through the spray pipe 43, forming a mist-like droplet that fully contacts the waste gas in the waste gas treatment box 2, removing the acidic gases through an acid-base neutralization reaction. The sprayed reaction liquid, carrying impurities, flows downwards, passing through the filter assembly 6 located at the port of the second connecting pipe 5. The filter holes 63 on the filter plate 61 intercept solid impurities. Simultaneously, the motor 64 drives the filter plate 61 to rotate, preventing the filter holes 63 at the second connecting pipe 5 from becoming clogged. As the filter plate 61 rotates, when the clogged filter hole 63 rotates to the position of the cleaning assembly 7... The high-pressure vacuum cleaner 71 is activated, using negative pressure to adsorb impurities on the surface of the filter plate 61; the cleaning roller 72 rotates synchronously, and the through-hole cone 73 on it is inserted into the filter hole 63, removing residual impurities in the hole through mechanical friction, ensuring that the filter assembly 6 continues to work effectively; the exhaust gas, after preliminary purification by the exhaust gas treatment box 2, enters the air purifier 8 through the third connecting pipe 9. In the third connecting pipe 9, the exhaust gas comes into full contact with the adsorption layer 12, and the adsorption materials such as activated carbon and molecular sieves further remove residual acidic gas molecules, organic pollutants and fine particulate matter through physical and chemical adsorption; the air purifier 8 performs deep treatment on the exhaust gas that has been preliminarily purified by the adsorption layer 12, decomposing volatile organic compounds through technologies such as photocatalytic oxidation module, and finally discharging the purified gas in compliance with emission standards.
