The thermodynamics analysis of a novel incinerator fecal treatment system

A novel incinerator fecal treatment system is developed. The system includes tilted rotation incinerator, frequency converter transmission mechanism, lavatory, solid-liquid separating unit, wobble pump, exhaust gas treatment device etc. In order to avoid the incinerator being jammed because of thermal expansion during rotation, the temperature field, thermal distortion and thermal stress of the incinerator are analyzed with Ansys software. The simulation result shows the incinerator´s highest temperature is 897 °C, the greatest deformation is 3.773 mm, the greatest thermal stress is 119 MPa during the burning process. Based on the analysis result, an incinerator prototype is developed. The experiment indicates the incinerator can work very well. Tested by authoritative department, the emission exhaust gas accords with GB 18485-2001 “standard for pollution control on the municipal solid waste incineration”.
