DETAILED DESCRIPTION

[0021] like Figure 1-6 As shown, a water washing tank for waste gas treatment includes a tank body 1, a gas outlet 2 is installed at the top center of the tank body 1, and an air intake device 3 is connected to the bottom side wall of the tank body 1 through an air intake pipe 4. A filter screen 18 installed downwardly tilted is installed at the air intake end of the air intake device 3 to filter out some impurities and prevent them from entering the water washing tank.

[0022] The bottom of the tank body 1 is connected to the water tank 13 through the water outlet pipe 14, and the top of the water tank 13 is connected to the water inlet 5 through the water inlet pipe 12. The water inlet 5 is located on one side of the top of the tank body 1. A spray device 11 is installed in the tank body 1, and the spray device 11 includes an upper spray plate 1101 and a lower spray plate 1102 symmetrically distributed up and down.
