Abstract

The invention discloses an oxygen-deficiency pyrolyzing circular sludge incinerator. The sludge incinerator comprises a incinerator body (02), a hearth bottom (28), a condenser (19) and a fan (21), wherein an incinerator cover (01) is arranged at the top of the incinerator body, a ventilation and smoke discharging hole (06) is arranged on the incinerator body, a circular combustion chamber (05) is arranged at the periphery of the upper middle part of the incinerator body, an air supply tuyere (15) is arranged at the outer wall of the circular combustion chamber, and the fan is connected with the air supply tuyere (15) through an air supply pipe (16); the hearth bottom comprises a circular ventilation room (08) and a barrel-shaped ventilation chamber (11), an incinerator thermal insulating layer (04) is arranged at the upper part of the incinerator body and the peripheries of the circular combustion chamber, the circular ventilation chamber and the barrel-shaped ventilation chamber; the upper part of the condenser is communicated with the upper part of the incinerator body through pipelines, and the condenser is connected with the fan through an air return pipe (24); and a condenser water outlet (20) is arranged at the bottom of the condenser. The oxygen-deficiency pyrolyzing circular sludge incinerator has the advantages of waste minimization, pollution-free disposal, waste recycling and the like.

Description

technical field [0001] The invention relates to sludge treatment equipment, in particular to a sludge incinerator. Background technique [0002] The pressure that China's development has brought to the environment is beyond imagination. In particular, the pollution pressure on water bodies has reached an unbearable level. In the domestic sewage treatment process, whether it is municipal sewage or industrial sewage, the disposal of sludge after sewage treatment has become an almost insurmountable problem. Whether the sludge disposal method is appropriate or not directly determines the quality of sewage treatment. At present, domestic sludge treatment and disposal methods are nothing more than agricultural use, landfill, construction utilization and partial mixed incineration. Each of these methods has advantages and disadvantages, and the disadvantages outweigh the advantages. For example, the use of sludge landfill will cause high sludge transportation costs; sludge will...
