The purpose of this utility model solves by the following technical programs:
A kind for the treatment of apparatus of trimellitic anhydride residue, comprise charging device, one side of charging device links to each other with high pressure positive blower, the opposite side of charging device links to each other with a side of incinerator, the opposite side of incinerator links to each other with a side lower part of secondary combustion chamber, the opposite side top of secondary combustion chamber links to each other with a side of cyclone dust collectors, the top of cyclone dust collectors links to each other with waste heat boiler by the energy recovery conduit, described incinerator is helicoid incinerator, is provided with the coating that is covered with the refractory brick inner surface on the inner surface of incinerator refractory brick; The side lower part that described secondary combustion chamber deviates from incinerator is provided with automatic soot blower system.
Described coating is made up of the high-temperature resistant anti-corrosive material.
Some temperature-detecting devices are set on the inner surface of described incinerator and secondary combustion chamber.
The top of described cyclone dust collectors is provided with the dump mouth, and the dump mouth communicates with the energy recovery conduit.
Described charging device feed motor-driven.
The utility model has following advantage compared to existing technology:
1, the utility model so the time of staying of trimellitic anhydride residue in incinerator increases, can burn the trimellitic anhydride residue owing to adopted helicoid incinerator fully;
2, one deck is high temperature resistant to be difficult for by the material of acid corrosion the utility model owing to being coated with on the inner surface of refractory brick, has prevented the surperficial coking corrosion of residue at refractory brick, and refractory brick is no longer easily come off, and has prolonged the life cycle of refractory brick;
3, the utility model can effectively prevent the surface knot ash of energy recovery conduit owing to be provided with automatic soot blower system in the inside of secondary combustion chamber, has increased the efficient of recuperation of heat;
4, the utility model is convenient to operation control owing to be provided with the plurality of temperature checkout gear in the inside of incinerator and secondary combustion chamber when making the whole system operation;
5, the utility model overall structure is stable, long service life, easy care easy for installation.
