[0001] This utility model relates to the field of environmental protection equipment technology for battery production, and more specifically, to a waste gas treatment device for battery production. Background Technology

[0002] With the rapid development of the new energy industry, the scale of battery production continues to expand, and various types of waste gas are generated during the production process. As a result, waste gas treatment devices for battery production have gradually developed. In the early days, waste gas treatment was mainly based on simple purification. With the improvement of environmental awareness and the improvement of relevant emission standards, waste gas treatment devices have gradually moved towards specialization and standardization.

[0004] (1) In actual use, the spray purification effect of the device is not well adapted to the process. It relies on a simple dispersion mechanism to disperse the waste gas, and cannot atomize the washing liquid into a fine mist. It is difficult to efficiently absorb soluble acid and alkali substances and trace harmful volatile substances in the battery production waste gas. The purification effect is poor, which affects the continuous operation of the equipment and cannot meet the high-efficiency pretreatment requirements of battery production waste gas.

[0005] (2) In actual use, the device has poor deep adsorption capacity and poor maintenance convenience, making it difficult to achieve standard emissions of waste gas. It cannot perform graded adsorption and catalytic decomposition of various harmful impurities such as VOCs, trace heavy metals, and residual acidic components in battery production waste gas. The waste gas purification is incomplete and cannot meet the long-term continuous and efficient purification requirements of battery production. Therefore, a waste gas treatment device for battery production is proposed. Utility Model Content

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0027] Example: Figure 1-6 As shown, this embodiment proposes a waste gas treatment device for battery production, including a spray tank 1, and a treatment mechanism 2 is provided on one side of the spray tank 1.

[0028] like Figure 2 , Figure 4 and Figure 5As shown, the treatment mechanism 2 includes a support frame 201 fixedly installed inside the spray tank 1. A filter plate 202 is provided on the top of the support frame 201, a guide tube 203 is fixedly installed on the bottom of the support frame 201, and a drain pipe 204 is fixedly installed on the bottom of the guide tube 203. A water storage tank 205 is provided on one side of the spray tank 1, and a water supply pipe 206 is fixedly installed on one side of the water storage tank 205. A water pump 207 is provided around the water supply pipe 206, and the water supply pipe 206 passes through the spray tank 1 and... Extending into the spray tank 1, a spray ring 208 is fixedly installed on the side of the water supply pipe 206 away from the water storage tank 205. Several spray heads 209 are fixedly installed around the spray ring 208. An air inlet pipe 210 is fixedly installed around the spray tank 1. A first air supply pipe 211 is fixedly installed on the top of the spray tank 1. An adsorption assembly 3 is provided on one side of the first air supply pipe 211. In use, the water storage tank 205 on one side of the spray tank 1 is used to store the spray washing liquid (a neutralizing liquid can be prepared according to the type of battery exhaust gas). (Absorbent, etc.) A water supply pipe 206 on one side of the water storage tank 205 is equipped with a water pump 207. The water is transported through the water supply pipe 206 to the spray ring 208 inside the spray tank 1. The spray ring 208 surrounds the inside of the spray tank 1, and several spray heads 209 are evenly installed around its perimeter. This atomizes the washing liquid into a fine mist, which fully contacts the battery production exhaust gas entering from the air inlet pipe 210. This efficiently absorbs soluble acid and alkali substances and trace amounts of harmful volatile substances in the exhaust gas, achieving preliminary purification of the exhaust gas. The support frame 201 inside the spray tank 1 serves as a top filter. Plate 202 provides stable support and can first intercept large particles of dust and solid impurities carried in the exhaust gas to ensure long-term stable operation of the equipment. At the same time, it slows down the exhaust gas flow rate, prolongs the contact time between the exhaust gas and the spray liquid, and improves the spray washing effect. The guide tube 203 at the bottom of the support frame 201 is used to collect the waste liquid after spraying. The drain pipe 204 at the bottom of the guide tube 203 discharges the waste liquid to prevent secondary pollution. The first gas supply pipe 211 at the top of the spray tank 1 transports the exhaust gas after spray washing to the adsorption component 3 for deep adsorption and purification.

[0029] like Figure 4 and Figure 5As shown, the adsorption assembly 3 includes an adsorption box 301 fixedly installed at the end of a first gas supply pipe 211 away from the spray tank 1. Several plug-in brackets 302 are fixedly installed on the top of the adsorption box 301. Alkali-impregnated porous ceramic plates 303, activated alumina catalyst plates 304, and zeolite molecular sieve plates 305 are plugged into the top of the plug-in brackets 302. A second gas supply pipe 306 is fixedly installed on one side of the adsorption box 301. In use, the end of the first gas supply pipe 211 away from the spray tank 1 is connected to the adsorption box 301. The adsorption box 301 provides a sealed space for deep adsorption of waste gas, preventing leakage of incompletely purified waste gas. The plug-in brackets 302 on the top of the adsorption box 301 allow for quick plugging and installation of alkali-impregnated porous ceramic plates 303, activated alumina catalyst plates 304, and zeolite molecular sieve plates 305. The alumina catalytic plate 304 and the zeolite molecular sieve plate 305 work synergistically to achieve multiple adsorption purification. The alkali-impregnated porous ceramic plate 303 can further neutralize the residual acidic components in the waste gas. The activated alumina catalytic plate 304 can catalytically decompose the harmful organic matter in the waste gas. The zeolite molecular sieve plate 305 can efficiently adsorb VOCs, odor molecules and trace heavy metal impurities in the waste gas. The triple adsorption catalysis thoroughly removes the harmful components in the waste gas, making the waste gas purification more thorough. The second gas supply pipe 306 on one side of the adsorption box 301 transports the deeply adsorbed waste gas to the disinfection structure for final disinfection treatment. The plug-in installation design facilitates the disassembly and replacement of the adsorption plates in the later stage, reduces maintenance costs, and is suitable for the long-term continuous operation requirements of battery production.

[0030] like Figure 5 and Figure 6 As shown, a disinfection tank 4 is fixedly installed on one side of the second gas supply pipe 306. Several UVC deep ultraviolet lamps 5 are fixedly installed around the disinfection tank 4. An exhaust pipe 6 is fixedly installed on the top of the disinfection tank 4. In use, the second gas supply pipe 306 sends the adsorbed waste gas into the disinfection tank 4. The several UVC deep ultraviolet lamps 5 fixed around the disinfection tank 4 can emit high-intensity deep ultraviolet light, which can effectively kill bacteria and microorganisms in the waste gas. At the same time, it can also help decompose residual trace amounts of harmful organic matter, further improving the quality of waste gas purification. The exhaust pipe 6 on the top of the disinfection tank 4 smoothly discharges the qualified waste gas after triple treatment (spraying + adsorption + disinfection) to the outside, realizing the harmless and environmentally friendly emission of waste gas.

[0031] like Figure 6As shown, an exhaust gas concentration detection sensor 7 is fixedly installed on the inner side of the exhaust pipe 6, and a controller 8 is fixedly installed on the top of the disinfection tank 4. The controller 8 is electrically connected to the exhaust gas concentration detection sensor 7, and an alarm 9 is fixedly installed on the top of the disinfection tank 4. The alarm 9 is electrically connected to the controller 8. The exhaust gas concentration detection sensor 7 is a Honeywell Sensepoint XCD. In use, the exhaust gas concentration detection sensor 7 fixed on the inner side of the exhaust pipe 6 can detect the concentration of the emitted exhaust gas in real time, accurately monitor whether the exhaust gas meets the standards, and transmit the detection data to the controller 8 on the top of the disinfection tank 4 in real time. The controller 8 is electrically connected to the exhaust gas concentration detection sensor 7 and the alarm 9 to form a closed-loop monitoring and early warning system: when the exhaust gas concentration exceeds the standard, the controller 8 immediately triggers the alarm 9 to emit a warning sound, promptly reminding staff to check for equipment malfunctions, avoid excessive exhaust gas emissions, and ensure environmental compliance.

[0032] like Figure 3 As shown, an observation slot 10 is provided on one side of the adsorption box 301, and an observation window 11 is fixedly installed on one side of the observation slot 10. In use, the observation slot 10 on one side of the adsorption box 301, together with the high-transparency observation window 11 fixed on the other side, allows the staff to directly observe the usage status of the internal adsorption plate, whether it is clogged with dust, and whether it has reached saturation without disassembling the adsorption box 301. This facilitates timely judgment and replacement of the adsorption plate, avoiding a decrease in the exhaust gas purification effect and excessive emissions due to the saturation of the adsorption plate. At the same time, it reduces equipment downtime for maintenance and ensures continuous and efficient operation of exhaust gas treatment.

[0033] like Figure 2 As shown, a water level groove 12 is provided on the periphery of the water storage tank 205. A scale plate 13 is fixedly installed on one side of the water level groove 12. In use, the water level groove 12 on the periphery of the water storage tank 205, together with the scale plate 13 fixed on one side, can intuitively display the water level of the spray washing liquid in the water storage tank 205. This makes it convenient for staff to replenish the washing liquid in a timely manner and avoid damage to the water pump 207 due to low water level, interruption of spraying, and impact on the exhaust gas treatment effect. The scale plate 13 has clear and wear-resistant graduations, making it easy to read and improving the ease of operation of the equipment.

[0034] like Figure 2 As shown, the guide tube 203 has several guide grooves 14 on its periphery. In use, the guide grooves 14 on the periphery of the guide tube 203 are designed with a downward smooth arc, which can accelerate the flow speed of the waste liquid after spraying, guide the waste liquid to quickly collect to the bottom of the guide tube 203, and discharge it through the drain pipe 204. This avoids the waste liquid from adhering and accumulating on the inner wall of the guide tube 203, reduces the cleaning frequency of the guide tube 203, lowers maintenance costs, improves the spray washing effect, and ensures the stability of the waste gas pretreatment.

[0035] Working Principle: This utility model provides a waste gas treatment device for battery production. The specific operating steps are as follows: A water storage tank 205 on one side of the spray tank 1 stores the spray washing liquid (neutralizing liquid, absorbent liquid, etc. can be configured according to the type of battery waste gas). A water supply pipe 206 on one side of the water storage tank 205 is connected to a water pump 207, which transports the liquid to the spray ring 208 inside the spray tank 1. The spray ring 208 surrounds the inside of the spray tank 1, and several spray heads 209 are evenly installed around its perimeter. These spray heads atomize the washing liquid into a fine mist, allowing it to fully contact the battery production waste gas entering from the air inlet pipe 210, efficiently absorbing soluble acid and alkali substances and microorganisms in the waste gas. The spray tank 1 contains harmful volatile organic compounds, achieving initial purification of the exhaust gas. The support frame 201 inside the spray tank 1 provides stable support for the top filter plate 202, intercepting large particles of dust and solid impurities carried in the exhaust gas to ensure long-term stable operation of the equipment. Simultaneously, it slows down the exhaust gas flow rate, prolonging the contact time between the exhaust gas and the spray liquid, thus improving the spray washing effect. The guide tube 203 at the bottom of the support frame 201 collects the waste liquid after spraying, and the drain pipe 204 at the bottom of the guide tube 203 discharges the waste liquid to prevent secondary pollution. The first gas delivery pipe 211 at the top of the spray tank 1 transports the sprayed exhaust gas to the adsorption component 3 for deep adsorption purification (e.g., ...). Figure 2 , Figure 4 and Figure 5 As shown), the end of the first gas supply pipe 211 furthest from the spray tank 1 is connected to the adsorption box 301. The adsorption box 301 provides a sealed space for deep adsorption of waste gas, preventing leakage of incompletely purified waste gas. Several plug-in brackets 302 on the top of the adsorption box 301 can be quickly plugged in and installed with alkali-impregnated porous ceramic plates 303, activated alumina catalyst plates 304, and zeolite molecular sieve plates 305. These work synergistically to achieve multiple adsorption purification. The alkali-impregnated porous ceramic plates 303 can further neutralize the residual acidic components in the waste gas, and the activated alumina catalyst plates... 304 catalytically decomposes harmful organic compounds in waste gas, while zeolite molecular sieve plate 305 efficiently adsorbs VOCs, odor molecules, and trace heavy metal impurities in the waste gas. This triple adsorption and catalysis thoroughly removes harmful components from the waste gas, resulting in more complete purification. The second gas supply pipe 306 on one side of the adsorption box 301 transports the deeply adsorbed waste gas to the disinfection structure for final disinfection. The plug-in installation design facilitates disassembly and replacement of the adsorption plates, reducing maintenance costs and adapting to the long-term continuous operation requirements of battery production (such as...). Figure 4 and Figure 5 (As shown).

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
