[0001] The present application relates to the technical field of battery material production dedusting, in particular to a dedusting system. BACKGROUND

[0002] The dedusting system usually uses high-mesh filter cloth to intercept dust particles in waste gas. However, although the high-mesh filter cloth can intercept most of the dust, some small particles will still pass through the filter cloth and be discharged into the environment, resulting in incomplete purification of waste gas. When the filter cloth is damaged or clogged, a large amount of dust will directly escape into the air, causing serious environmental pollution. The filter cloth needs to be replaced regularly, and the equipment needs to be shut down for maintenance after the filter cloth is damaged, increasing the maintenance cost and production downtime of the equipment.

[0022] Please refer to Figure 1 The embodiment of the present application provides a dust removal system 10, which comprises a dust removal bin 100, a fan 200 and a filtering device 300. The dust removal bin 100 comprises an air inlet 101 and an air outlet 102, and is configured to filter and separate a gas-solid mixture and preliminarily intercept large-particle dust in waste gas. The fan 200 is connected with the air outlet 102, and is configured to extract waste gas in the dust removal bin 100. The fan 200 extracts waste gas by generating a negative pressure air flow and delivers the waste gas to the subsequent filtering device 300. The filtering device 300 comprises a first filtering assembly 310 and a second filtering assembly 320. The first filtering assembly 310 comprises a water tank 311. The water tank 311 is connected with the fan 200, and is configured to receive waste gas extracted by the fan 200, and liquid (such as water) in the water tank 311 can adsorb solid waste in the waste gas. The second filtering assembly 320 is connected with the water tank 311. The second filtering assembly 320 comprises a circulating water device 321, which is configured to filter water in the water tank 311 and flow filtered water into the water tank 311 for circulation.

[0023] The application can improve the trapping capacity of micro dust particles through the double filtering mechanism of the water tank 311 and the circulating water device 321, and can more thoroughly purify the dust in the exhaust gas compared with the traditional high-mesh filter cloth, thereby reducing environmental pollution. The application realizes secondary purification of the exhaust gas and improves the purification effect of the exhaust gas. The water tank 311 is used as the first filtering assembly 310, so that even if the filter cloth in the dust removal bin 100 is damaged or blocked, the dust can be effectively intercepted through the adsorption of water. The circulating water device 321 can continuously filter and reuse water resources, thereby reducing the need for frequent replacement of the filter cloth in the dust removal bin 100 and reducing the equipment downtime maintenance time and maintenance cost.

[0024] Please refer to Figure 1 In an embodiment of the application, the second filtering assembly 320 further includes a first pipe 322 and a second pipe 323. The first pipe 322 is connected to the bottom of the water tank 311, and the first pipe 322 is configured to receive water in the water tank 311. The second pipe 323 is connected to the top of the water tank 311, and the second pipe 323 is configured to discharge the filtered water from the circulating water device 321 into the water tank 311 for circulation. By providing the first pipe 322 and the second pipe 323, a complete water circulation channel is formed, so that the water in the water tank 311 can be continuously circulated and filtered. The first pipe 322 receives waste water from the bottom of the water tank 311, which can ensure that the filtering device 300 can fully utilize the water resources in the water tank 311, and the second pipe 323 reintroduces the filtered water into the top of the water tank 311 to promote uniform circulation of the water body. At the same time, the structure of the circulating water device 321 is simplified, and the convenience of maintenance of the dust removal system 10 is improved.

[0025] Please refer to Figure 1 In an embodiment of the application, the circulating water device 321 includes a first-stage filtering tank 324 and a second-stage filtering tank 325 that are in communication with each other. The first-stage filtering tank 324 is in communication with the first pipe 322, and the second-stage filtering tank 325 is in communication with the second pipe 323. The first-stage filtering tank 324 is configured to preliminarily filter the water in the water tank 311. The second-stage filtering tank 325 is configured to finely filter the water in the first-stage filtering tank 324. By adopting a two-stage filtering structure, the water treatment is divided into two stages of preliminary filtering and fine filtering, thereby effectively improving the level and efficiency of water purification. The first-stage filtering tank 324 can remove particulate impurities and suspended solids by preliminarily filtering the water in the water tank 311, thereby reducing the subsequent filtering pressure and prolonging the service life of the second-stage filtering tank 325. The second-stage filtering tank 325 further finely filters the water quality to trap smaller pollutants, thereby significantly improving the water quality of the outlet water. The multi-stage deep purification of the water quality is ensured, and the operation efficiency and economy of the dust removal system 10 are improved.

[0026] Please refer to Figure 1In an embodiment of the present application, the first filter material 326 is arranged between the first pipeline 322 and the first filter tank 324, and is configured to filter the water delivered by the first pipeline 322. By arranging the first filter material 326 between the first filter tank 324 and the first pipeline 322, the larger particles and impurities in the water body can be effectively intercepted and treated, so as to ensure that the water entering the first filter tank 324 is preliminarily purified.

[0027] Referring to Figure 1 In an embodiment of the present application, the second filter material 327 is arranged between the first filter tank 324 and the second filter tank 325, and is configured to filter the water delivered by the first filter tank 324. By arranging the second filter material 327 between the first filter tank 324 and the second filter tank 325, the water body is provided with further fine interception function. The second filter material 327 can further filter the small particle impurities that cannot be intercepted in the first filter tank 324, so as to further improve the water quality. Through reasonable selection and layered arrangement of the filter material, the water circulation function of the circulating water device 321 can be ensured.

[0028] Referring to Figure 1 In an embodiment of the present application, the third filter material 328 is arranged between the second filter tank 325 and the second pipeline 323, and is configured to filter the water delivered by the second filter tank 325. The arrangement of the third filter material 328 further improves the water quality of the second filter tank 325. By finely filtering the water delivered by the second filter tank 325, the third filter material 328 can effectively remove the tiny particles and suspended solids in the water, so as to ensure that the water entering the second pipeline 323 and finally returning to the water tank 311 is more pure. Not only the water circulation efficiency is improved, but also the equipment damage caused by waste blockage problem is reduced.

[0029] Referring to Figure 1 In an embodiment of the present application, the first filter material 326, the second filter material 327 and the third filter material 328 are all molecular sieves. By adopting molecular sieves as filter materials, the overall performance and filtering precision of the circulating water device 321 are further improved. The molecular sieves have extremely high molecular selectivity, can effectively remove impurities of a specific size in the water, and can adsorb tiny particles and organic pollutants in the water. In addition, the combination of molecular sieves makes the filter material more durable, can withstand higher water pressure and flow, and the good chemical resistance of the filter material also enables the filter material to maintain stable filtering effect under different water quality conditions.

[0030] Referring to Figure 1In an embodiment of the present application, the first filtering box 324 is provided with a blowdown port 329 configured to discharge the filtered residue. Through the blowdown port 329, the operator can quickly clean the filtered residue and impurities, avoiding the problem of reduced filtering efficiency or filter clogging caused by residue accumulation in the conventional filtering device 300. The design of the blowdown port 329 also greatly reduces maintenance costs, reduces the need for frequent replacement of the filtering box, and improves the operation efficiency and sustainability of the dust removal system 10.

[0031] Referring to Figure 1 In an embodiment of the present application, the first filtering assembly 310 further includes a fourth filter material 312. The fourth filter material 312 is arranged in the water tank 311 and is configured to filter the exhaust gas drawn by the fan 200. By arranging the fourth filter material 312, the fourth filter material 312 can remove large particulate matter such as dust from the exhaust gas drawn by the fan 200, which helps the water body to adsorb the exhaust gas.

[0032] Referring to Figure 1 In an embodiment of the present application, the fourth filter material 312 is filter cotton. By arranging the filter cotton, the efficiency and effect of filtering the exhaust gas are further improved. The filter cotton has a large specific surface area and good adsorption performance, which can effectively trap particulate matter and harmful gases in the exhaust gas drawn by the fan 200 in the water tank 311.
