Description

Technical Field

[0001] This utility model belongs to the field of waste gas purification technology, specifically a waste gas purification device for power battery recycling. Background Technology

[0002] When power batteries are used for a long time, their efficiency will drop significantly, making it impossible to achieve the effects of energy storage and driving. In order to avoid environmental pollution, hydrochloric acid is usually used to soak the power batteries. During the treatment process, a large amount of waste gas is generated. In order to avoid environmental pollution, the waste gas usually needs to be purified by waste gas purification equipment to meet emission standards. Among them, spray tower treatment is a more important part of the waste gas purification process of power battery recycling.

[0003] In existing technologies, when recycling power batteries, the spray nozzles of the spray tower can prevent the accumulation of circulating liquid during spraying. However, when spraying stops, due to negative pressure, the circulating liquid will accumulate in the spray nozzle area. This accumulation is prone to mixing with internal dust and acidic substances to form crystals, which can lead to blockage over time and directly affect the effect of exhaust gas treatment.

[0009] Preferably, a limiting sleeve is fixedly installed on the inner side of the fixed rod, and a rotating rod is rotatably provided on the inner side of the limiting sleeve, with a rotating fan blade fixedly installed on the top of the rotating rod.

[0010] Preferably, a number of guide arc plates are installed on the inner side of the lower end of the spray head, and the guide arc plates are located above the rotating fan blades. An atomizing disc is fixedly installed at the bottom of the rotating rod, and four sets of scrapers are installed on the top of the atomizing disc. The end of the scraper away from the atomizing disc is in close contact with the bottom of the spray head.

[0011] Preferably, a waste gas inlet pipe is installed on one side of the spray tower, and four sets of support rods are installed at the bottom of the spray tower. A collection tank is welded to the outer side of the lower end of the four sets of support rods. A circulation pump assembly is connected to the side of the collection tank away from the waste gas inlet pipe through a pipe, and a drive motor is installed on the top of the circulation pump assembly.

[0012] Preferably, a set of arc-shaped pipes is installed on the side of the spray pipes away from the exhaust gas inlet pipe, and fixed supports are installed at both ends of the arc-shaped pipes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the combination of a sealing component and a vent, facilitates the expulsion of accumulated circulating liquid in the nozzle area via ventilation, thus preventing crystallization caused by the accumulation of circulating liquid mixing with air. A fixing ring provides an installation position for the support spring and the top structure. During spraying, the liquid pushes the sealing cone and sealing ring downwards along the inner side of the spray head, blocking the vent on the side wall of the spray head and ensuring normal spraying. When spraying stops, the elasticity of the support spring pushes the sealing ring upwards, separating it from the vent to connect with the outside. Simultaneously, the sealing cone blocks the conical ring to prevent liquid dripping from inside the spray pipe, and gas entering through the vent discharges the accumulated liquid inside, preventing crystallization and effectively avoiding the problem of reduced waste gas treatment efficiency caused by nozzle blockage.

[0027] like Figures 1 to 6 As shown, this utility model provides a waste gas purification device for power battery recycling, including a spray tower 100. The spray tower 100 is provided with a number of spray pipes 109 inside, and a number of spray heads 200 are provided at the bottom of the spray pipes 109. A sealing component 001 is provided on the inner side of the spray head 200.

[0028] The sealing assembly 001 includes a fixing ring 301, and a support spring 302 is embedded in the top of the fixing ring 301. A sealing ring 300 is fixedly installed on the top of the support spring 302, and a sealing cone 305 is fixedly installed in the middle of the lower end of the sealing ring 300. A conical ring 303 is fixedly installed on the inner side of the upper end of the spray head 200. The sealing cone 305 is movably installed at the bottom of the conical ring 303. Several sets of ventilation holes 202 are opened on the side wall of the spray head 200.

[0029] Using the above scheme: the spray tower 100 can filter the exhaust gas entering the interior, the spray pipe 109 can guide and transport the circulating spray liquid, the spray head 200 can provide an installation position for the internal structure and can export the internal liquid for spray treatment, the fixing ring 301 can be connected to the spray head 200 and provide support for the top support spring 302, the support spring 302 can push the closing ring 300 to reset through elasticity, and after reset, the vent hole 202 can be opened. During the rising process of the sealing cone 305, it will squeeze and embed into the inner side of the conical ring 303, thereby achieving the sealing effect and preventing the internal liquid from continuing to flow out.

[0030] like Figure 3 - Figure 5 As shown, several sets of connecting rods 304 are installed on the outer side of the closed cone 305, and the connecting rods 304 are fixedly installed on the inner side of the lower end of the closed ring 300.

[0031] A three-way pipe 201 is installed on the outer side of the upper end of the spray head 200, and the three-way pipe 201 is fixedly installed on the outer side of the spray pipe 109. Several sets of fixing rods 402 are installed on the inner side of the lower end of the spray head 200.

[0032] A limiting sleeve 403 is fixedly installed on the inner side of the fixed rod 402, and a rotating rod 405 is rotatably provided on the inner side of the limiting sleeve 403. A rotating fan blade 404 is fixedly installed on the top of the rotating rod 405.

[0033] Several sets of guide arc plates 401 are installed on the inner side of the lower end of the spray head 200, and the guide arc plates 401 are located above the rotating fan blades 404. An atomizing disc 400 is fixedly installed at the bottom of the rotating rod 405, and four sets of scraper blades 406 are installed on the top of the atomizing disc 400. The end of the scraper blade 406 away from the atomizing disc 400 is in close contact with the bottom of the spray head 200.

[0034] The above scheme is adopted as follows: the connecting rod 304 is used to connect the closed cone 305 and the closed ring 300. After connection, synchronous up and down sliding adjustment can be ensured. The three-way pipe 201 can be used to connect the spray head 200 and the spray pipe 109. After connection, normal liquid supply can be achieved. The fixing rod 402 can fix the limiting sleeve 403 to the inner wall of the spray head 200. The limiting sleeve 403 can provide a restriction for the inner rotating rod 405, assisting the rotating rod 405 to rotate and adjust. The rotating fan blade 404 at the top can achieve the rotation effect under the impact of the water flow. In addition, the guide arc plate 401 can further increase the rotation speed of the rotating fan blade 404. By increasing the rotation speed, the discharged water flow can be further dispersed by the atomizing disc 400, improving the mixing effect with the exhaust gas and achieving the dust removal effect. The simultaneous rotation of the scraper 406 can scrape off the crystals attached to the bottom of the spray head 200, avoiding the problem of accumulation and opening blockage.

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, a waste gas inlet pipe 101 is installed on one side of the spray tower 100, and four sets of support rods 102 are installed at the bottom of the spray tower 100. A collection tank 103 is welded and installed on the outer side of the lower end of the four sets of support rods 102. A circulation pump assembly 104 is connected to the side of the collection tank 103 away from the waste gas inlet pipe 101 through a pipe, and a drive motor 105 is installed on the top of the circulation pump assembly 104.

[0036] A set of arc-shaped pipes 107 is installed on the side of several sets of spray pipes 109 away from the exhaust gas inlet pipe 101, and fixed brackets 108 are installed at both ends of the arc-shaped pipes 107. The fixed brackets 108 are fixedly installed on the side of the upper end of the spray tower 100 away from the exhaust gas inlet pipe 101. A transmission pipe 106 is installed in the middle of the arc-shaped pipes 107, and the transmission pipe 106 is fixedly connected to the output end of the circulating pump assembly 104.

[0037] A clean air pipe 110 is installed on the top of the spray tower 100, and two sets of filter layers 112 are provided inside the spray tower 100. The filter layers 112 are located below the spray head 200, and a demister 111 is fixedly installed on the inner side of the upper end of the spray tower 100.

[0038] The above scheme is adopted as follows: the exhaust gas inlet pipe 101 is used to introduce the exhaust gas generated by battery recycling into the interior of the spray tower 100. The support rod 102 can provide support for the top spray tower 100. The collection tank 103 can collect the liquid sprayed inside and filter and guide the return flow through the circulation pump assembly 104. The drive motor 105 can provide power support for the circulation pump assembly 104. The arc-shaped pipe 107 is used to connect the various spray pipes 109. The transmission pipe 106 can be connected to the spray pipe 109 through the arc-shaped pipe 107, thereby achieving the effect of guiding the liquid to spray. The fixed bracket 108 can fix the arc-shaped pipe 107 to the side of the upper end of the spray tower 100 to ensure the stability of the structure. The moisture of the rising gas can be separated by setting the demister 111. The filter layer 112 can be used in conjunction with the spray structure to filter the exhaust gas.

[0039] The working principle and usage process of this utility model are as follows: Waste gas generated from the recycling of power batteries is introduced into the spray tower 100 through the waste gas inlet pipe 101. During the introduction process, the circulating pump assembly 104 filters the liquid inside the collection tank 103 and introduces it into the arc-shaped pipe 107 through the transmission pipe 106, then diverts it into each group of spray pipes 109. After injection, the liquid pressure gradually increases, and continuous injection squeezes and separates the sealing cone 305 from the conical ring 303. During the separation process, the connecting rod 304 drives the sealing ring 300 to move downwards and block the vent hole 202. The liquid continues to flow downwards... Sliding along the guide arc plate 401 and impacting the rotating fan blade 404, the rotating fan blade 404 will drive the rotating rod 405 to rotate along the inner side of the limiting sleeve 403 during the rotation. During the rotation, the scraper 406 scrapes off the crystals at the bottom of the spray head 200. During the spraying process, the filter layer 112 is used to filter the exhaust gas. When the spraying stops, the support spring 302 will push the sealing cone 305 to reset and seal the opening area of ​​the conical ring 303. At the same time, the sealing ring 300 separates from the vent hole 202, allowing the gas to be introduced into the interior and the liquid accumulated inside to be discharged.
