Return material temperature control system and method of household garbage pyrolysis treatment system

Abstract

The invention belongs to the technical field of pyrolysis, and particularly relates to a return material temperature control system and method of a household garbage pyrolysis treatment system. The device comprises a solid heat carrier furnace, a cyclone separator, a material level measuring instrument A, a material level measuring instrument B, a material level measuring instrument C, a material level measuring instrument D, a garbage feeding controller, a pyrolysis reactor, a middle stock bin, a material level measuring instrument E, a material level measuring instrument F, a material level measuring instrument G, a material level measuring instrument H, a material returning controller, a garbage hopper and a dipleg. Pyrolysis residual carbon and pyrolysis gas in the solid heat carrier furnace are subjected to combustion oxidation reaction in the furnace, high-temperature flue gas carries a heat carrier to enter the cyclone separator, hot flue gas moves upwards to a flue gas purification system, and the heat carrier precipitates downwards to the dipleg. According to the technical scheme, material returning temperature control of material sealing priority in the pyrolysis process can be achieved, and the problems of hysteresis quality, coupling performance and anti-explosion safety under complex working conditions are solved.

Description

technical field [0001] The invention belongs to the technical field of pyrolysis, and in particular relates to a return material temperature control system and method of a household garbage pyrolysis treatment system. Background technique [0002] The amount of heat carrier in the set temperature range that enters the reactor is controlled by the feeding controller, and is fully mixed with the material with the same feed amount controlled in the reactor, heat transfer, and pyrolysis. The products include gas, oil, carbon, Residue, etc., the heat carrier that accounts for the largest proportion in its solid materials, its temperature will be lower than that of the inlet, and the solid residue after pyrolysis will increase, fully mixed after stirring in the reactor, and buffered in the intermediate silo Finally, it enters the heat carrier furnace through the feeder. The temperature of the material before the feeder is used as the return temperature, which plays a vital role in...
