It uses an incinerator to heat and dry the dehydrated sludge, and then oxidizes the organic matter in the sludge with high temperature to turn the sludge into a small amount of ash. It is a reduction, stabilization and harmless treatment method for sludge treatment. This method can completely remove the water and organic matter in the sludge and kill pathogens.

[0003] Among them, a sludge drying tail gas purification device based on sludge treatment is proposed in the prior art with the authorization announcement number CN215411907U, including a treatment box, wherein an ejection mechanism is arranged inside the treatment box; the ejection mechanism includes a lifting plate slidably connected between the inner walls of the treatment box, a slide groove is provided at the bottom of the inner wall of the treatment box, a slider is slidably connected to the inner surface of the slide groove, a screw rod is rotatably connected between the left and right sides of the inner wall of the slide groove, the left end of the screw rod penetrates the treatment box and extends to the left side of the treatment box, a motor is fixedly connected to the left side of the treatment box, and the output end of the motor is fixedly connected to the left end of the screw rod through a coupling;

[0004] Sludge will generate a lot of heat during the incineration process. Without heat insulation devices, it is easy to cause equipment damage.
