Pyrolysis drying device for water-containing sludge

Abstract

The invention relates to the field of sludge treatment, in particular to a water-containing sludge pyrohydrolysis drying device which comprises a tank body, three supporting seats are fixedly connected to the bottom end of the tank body, the three supporting seats are annularly and evenly distributed on the side close to the outer surface of the tank body, and a motor is vertically installed at the top end of the tank body and located in the center of the tank body; one end of an output shaft of the motor penetrates through the top end of the tank body and is fixedly connected with a stirring mechanism, the stirring mechanism is rotationally connected with the inner wall of the tank body, an air injection mechanism is fixedly connected to the bottom end of the inner wall of the tank body and located below the stirring mechanism, and a material injection opening is formed in the top end of the tank body and located on one side of the motor; an air outlet is formed in the top end of the tank body and located on the other side of the motor, an air inlet is formed in the center of the bottom end of the tank body, and a discharge port is formed in the outer surface of the tank body and close to one side of the bottom end of the stirring mechanism; and according to the sludge thermal hydrolysis device, by arranging the stirring mechanism and the air injection mechanism, the mixing efficiency of steam and sludge can be improved, and the sludge is subjected to sufficient thermal hydrolysis.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a thermal hydrolysis drying device for aqueous sludge. Background technique [0002] A large amount of sludge will be generated in the existing sewage or wastewater treatment process, and random stacking of sludge will not only take up a lot of space. Thermal hydrolysis of sludge is a common way to treat sludge. Usually, sludge is put into a thermal hydrolysis container and kept at high temperature and high pressure for a certain period of time to realize thermal hydrolysis of sludge. After decomposing, the sludge is transported to the next treatment link. [0003] However, in the prior art, internal parts are usually not installed in the thermal hydrolysis tank, resulting in a short steam flow path, low mixing efficiency of steam and sludge, and insufficient thermal hydrolysis of the sludge. [0004] For this reason, a thermal hydrolysis drying device for aqueous sludge is prop...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a thermal hydrolysis drying device for water-containing sludge, which mainly solves the problem that internal parts are not installed in the thermal hydrolysis tank, resulting in a short flow of steam and low mixing efficiency of steam and sludge. The problem that the sludge cannot be fully thermally hydrolyzed
