[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within enterprise factories. Industrial waste gas black smoke refers to waste gas containing a large amount of particulate matter generated during industrial production, which has a serious impact on the environment and human health. In order to protect the environment and human health, industrial black smoke waste gas needs to be purified.

[0003] Its application number is "202021635651.5" disclosed "an energy-saving and environmentally friendly industrial waste gas purification equipment", which "comprises a shell, a cylindrical hollow ring frame is welded at the bottom of the inner wall of the shell, a filter element is nested in the inner wall of the ring frame, a hoop is welded on the upper end of the filter element, the ring frame is filled with liquid, and a shell cover is clamped on the upper end of the shell". In this utility model, through the arrangement of the filter element and the ring frame, the external industrial device is connected through the exhaust pipe, the exhaust gas enters the trachea through the exhaust pipe through the air intake pipe, and the exhaust gas is discharged into the liquid in the ring frame. If it needs to be explained, the neutralizer added to the liquid according to the actual situation and the actual situation needs to be determined. The dust is blocked by the liquid, and the filter element also blocks the leakage of dust, so as to avoid direct discharge of industrial waste gas to cause environmental pollution or inhalation by people causing irreversible physical damage.

[0004] However, the above method still has the following defects: the dust can be prevented from leaking out by liquid and filter element, but it is not convenient to clean the filter element. The cleaning process requires opening the shell cover with a buckle and taking out the exhaust pipe before the filter element can be removed. It is labor-intensive and time-consuming and inconvenient to operate. If the cleaning is not timely, the filter pores of the filter element may be easily clogged, which will reduce the emission efficiency of the exhaust gas. Utility Model Content
