Vehicle-mounted household refuse microwave pyrolysis disposal system

Abstract

A vehicle-mounted household refuse microwave pyrolysis disposal system comprises a discharge hopper, a crusher, a screw extrusion dehydrator, a stirring mixer, a hot air unit, a drying box, a microwave pyrolysis device, a gas secondary pyrolysis device, a condensation system and a gas filtration device. The discharge hopper is connected with a receiving hopper of the crusher through a conveying belt, a discharge port of the screw extrusion dehydrator is aligned with the conveying belt, a discharge port of the crusher is connected with stirring mixer, and a discharge port of the stirring mixeris connected with the drying box. A discharge port of the drying box is connected with the microwave pyrolysis device, the microwave pyrolysis device is connected with the gas secondary pyrolysis device, the gas secondary pyrolysis device is connected with the condensation system, and the condensation system is connected with the gas filtration device. Gas produced by microwave pyrolysis is subjected to secondary pyrolysis, so the system has no discharge of combustion, flying ash or harmful gas.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a vehicle-mounted microwave cracking treatment system for domestic waste. Background technique [0002] At present, my country produces nearly 1 billion tons of urban waste every year, including nearly 500 million tons of domestic waste, and it is still growing at an average annual rate of about 10%. For a long time, my country's domestic waste treatment mainly adopts composting, landfilling and incineration. Garbage composting has a small amount of treatment, large limitations, and slow processing speed; landfills occupy a large amount of land resources, soil restoration is difficult, leachate and landfill gas have a low degree of harmless treatment, and the service life of landfills is short; A relatively thorough harmless treatment technology has developed rapidly in China in recent years, but it also has disadvantages such as large investment, high operating cos...
