Description

Technical Field

[0001] The utility model relates to the technical field of tail gas collection, in particular to a device for collecting and purifying automobile tail gas. Background Art

[0002] In the prior art, the patent with announcement number CN220238177U discloses an automobile exhaust gas collection and purification device, which includes a plurality of detection chambers and a filter tank body. The exhaust gas output ends of the plurality of detection chambers are fixedly connected together and connected with a parallel pipe. The output end of the parallel pipe is fixedly connected with an output main pipe. The output end of the output main pipe is connected with the interior of the filter tank body. The plurality of detection chambers each include a detection chamber body. The advantages of the utility model are that: by providing an air curtain machine and an absorption tank, an air curtain is formed at the door of the detection chamber body. The air curtain can effectively close the door and reduce the leakage of exhaust gas. At the same time, the exhaust gas blown off by the air curtain can be quickly blown away by the absorption tank and the vacuum machine, thereby improving the exhaust gas discharge efficiency. By providing a one-way valve at the output end of each detection chamber body, when any detection chamber body is used alone, the other detection chamber bodies do not need to be closed, and there is no need to close the valves one by one, thereby improving convenience.

[0003] In actual use, although the above-mentioned equipment can purify and detect automobile exhaust very well, after the exhaust gas is cleaned, a large amount of impurities and oil will adhere to the inner wall of the filter tank body. However, the existing filter tank body is not provided with a structure for cleaning the inner wall of the filter tank body. Therefore, after long-term use, even if clean cleaning water is continuously injected into the filter tank body, the exhaust gas purification efficiency will still be reduced. At the same time, the existing equipment is not provided with a structure for recycling used water, so a large amount of water resources will be wasted during use.

[0004] Therefore, a device for collecting and purifying automobile exhaust gas is proposed. Utility Model Content
