[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3The waste incineration flue gas treatment device shown in the figure includes a device shell 100, an air inlet pipe 101 is fixedly plugged into the middle of the device shell 100, and one end of the air inlet pipe 101 extending to the inner cavity of the device shell 100 is bent downward and connected to a gas diffusion cover 102. The end of the air inlet pipe 101 entering the device shell 100 is bent downward, which can prevent the entry of liquid dripping downward. At the same time, in conjunction with the gas diffusion cover 102, the range of gas dispersal can be increased and the gas outlet efficiency can be improved. An outlet 111 for gas discharge is opened at the top of the device shell 100, and the cleaned gas is discharged from the device shell 100 through the outlet 111. A shower nozzle 103 is provided on the top of the inner cavity of the device shell 100. The shower nozzle 103 is used for spraying liquid. Liquid is sprayed downward, and the falling liquid contacts the rising flue gas, thereby achieving the purpose of flue gas washing and removing water-soluble impurities in the flue gas. The water filter plate 105 is fixedly connected to the middle of the bottom end of the inner cavity of the device shell 100, and the top of the water filter plate 105 is fixedly connected to an inclined shielding plate 104, and the outer wall of the shielding plate 104 is fixedly connected to the inner wall of the device shell 100. The water filter plate 105 and the shielding plate 104 cooperate to enclose a space at the bottom of the device shell 100. After the washed waste water falls to the bottom of the device shell 100, after being filtered by the water filter plate 105, the liquid without solid impurities enters the area between the shielding plate 104 and the water filter plate 105, so that the liquid in this area can be reused for flue gas washing. A waste outlet 110 is provided at the bottom of the side wall of the device housing 100. The waste outlet 110 is provided to facilitate the discharge of cleaning waste water when the inside of the device housing 100 is cleaned. The two-way pump 107 is fixedly installed on the outer wall of the device housing 100. The two-way pump 107 is used to provide power for liquid transmission. The two-way pump 107 can extract the liquid between the baffle plate 104 and the water filter plate 105 inside the device housing 100. The three ports of the three-way valve 200 are respectively fixedly connected to the water inlet of the shower head 103, the external water pipe and one end of the two-way pump 107.
