As one of the major pollution sources, waste gas treatment in sewage stations has been increasingly recognized and valued by people. The existing waste gas demisting devices in sewage stations have poor gas-liquid separation effects, and when the micro-foam demisting equipment is in use, the large liquid attached to the wave folding plate is difficult to fall quickly, which not only leads to low discharge efficiency, but also makes it easy for large liquids to remain on the wave folding plate, which leads to poor demisting effects.

[0003] Therefore, we have made improvements to this and proposed a micro-foam demisting equipment specifically for waste gas treatment in sewage stations. Utility Model Content

[0029] A circular defoaming plate 15 is fixedly mounted on the inner wall of the exhaust gas treatment device housing 1 and between the motor 5 and the exhaust pipe 6 .

[0030] In this embodiment, Figure 1-2 As shown, a maintenance port is provided on the side end surface of the exhaust gas treatment equipment housing 1, and a transparent maintenance plate 2 is installed at the maintenance port.

[0031] The working process inside the exhaust gas treatment device housing 1 can be observed through the transparent maintenance plate 2. The transparent maintenance plate 2 can be opened to clean and maintain the exhaust gas treatment device housing 1 through the maintenance port.

[0032] A plurality of support legs 3 are fixedly mounted in a circular array at the lower end of the fixed ring frame 4 , and a support plate is fixedly mounted at the lower end of the support leg 3 .

[0033] like Figure 3-4 As shown, a vertically arranged cleaning shaft 17 is rotatably mounted on the top surface of the inner shell 1 of the exhaust gas treatment equipment, and the lower end of the cleaning shaft 17 passes through the center of the circular defoaming plate 15. A cleaning scraper 14 is fixedly mounted on the cleaning shaft 17, and the upper end of the cleaning scraper 14 fits the lower end surface of the circular defoaming plate 15.
