Tail gas purification device for extracting pyrite from cyanide slag

Abstract

The invention relates to the technical field of tail gas purification and separation, and provides a tail gas purification device for extracting pyrite from cyanided slag, the tail gas purification device comprises a tail gas collection unit, a pretreatment unit, a separation unit, an absorption unit and a control unit, the separation unit comprises a tower body, a spraying mechanism and a filler loading and unloading mechanism, the spraying mechanism is connected with the tower body, and the absorption unit is connected with the tower body; the spraying device is used for spraying a treatment solution into the tower body. According to the purification device, the filler loading and unloading mechanism is arranged, so that the purification device has an automatic filler loading and unloading function, the paving assembly and the stirring assembly are arranged on the stacking plate, the automatic paving and discharging functions of the filler can be completed, manual replacement operation is replaced, the workload of workers is reduced, and the working efficiency is improved. And the whole replacement process is carried out in the tower body, so that the harm of harmful substances in the tower body to a human body can be reduced.
