[0002] Lead-zinc smelting is an important industrial process aimed at extracting lead and zinc metals from ores. This process includes two steps: crude lead smelting and refining. Among them, the crude lead smelting process mainly includes the oxidation and desulfurization of lead sulfide concentrate, reduction smelting, and lead slag separation, and finally produces crude lead.
[0003] When the existing equipment treats flue gas, the filtering effect is too poor, which easily leads to a large amount of harmful substances in the flue gas. At the same time, the flue gas will stay inside the equipment, resulting in too many impurities such as oil stains remaining inside the equipment, which easily causes the equipment to be damaged. At the same time, a large amount of oil stains and impurities contained in the flue gas will also be discharged to the outside along with the flue gas, and will adhere to the filter plate, resulting in poor subsequent filtering effect. Therefore, we propose a flue gas pretreatment device for lead-zinc smelting. Summary of the Utility Model

[0026] As shown in Figure 3 , on the outer wall of one side of the fixing plate 107 away from the adapter pipe 106 is fixedly connected with a motor 108. When the motor 108 starts, it will drive the rotating shaft 109 to rotate. The bottom output end of the motor 108 is fixedly connected with a rotating shaft 109, and the rotating shaft 109 penetrates through the treatment tank 103 to the outside.
[0027] As shown in Figure 3 , the inner wall of the adapter pipe 106 is fixedly connected with a number of connecting plates 110. The outer wall of one side of the connecting plate 110 away from the adapter pipe 106 is fixedly connected with a fixing ring 111.

The outer wall of the rotating rings 2 is fixedly connected with a number of rotating plates 201, and the outer wall of the rotating plates 201 is fixedly connected with an adsorption filter plate 202.
[0029] As shown in Figure 2-5 , the inner walls of a number of adapter pipes 106 are all fixedly connected with second filter plates 203. When the flue gas passes through the second filter plates 203, the filtering effect on the remaining flue gas will be enhanced. The outer wall of one side of the adapter pipe 106 away from the treatment tank 103 is fixedly connected with a discharge tank 204.
