Abstract

The invention discloses a garbage drying and pyrolyzing method. The method comprises the following steps that pyrolytic garbage is poured into a feeding hopper, the garbage enters an extrusion cylinder, a driving motor is started to drive an extrusion rotating shaft to rotate, the garbage moves rightwards under the action of a spiral blade, the garbage is extruded through the inner wall of the extrusion cylinder to discharge water, sewage drips into a sewage tank and is discharged from a sewage outlet, and the garbage enters a crushing box from a first discharging opening; a crushing motor isstarted to drive a first crushing shaft and a second crushing shaft to rotate, crushing blades on the crushing shafts crush the garbage, and the crushed garbage enters a drying box; and a first heating plate, a second heating plate and a fan are started to dry the garbage in the drying box, generated gas enters a dust removal water tank from an exhaust pipe, an electric valve at the bottom of thedrying box is opened, and the dried garbage is discharged into a pyrolyzing furnace. According to the method, the moisture content in the garbage is greatly reduced, the pyrolysis speed of the garbagein the pyrolyzing furnace is increased, residues are reduced, and generated gas does not contain a large amount of incineration particles.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a garbage drying and pyrolysis method. Background technique [0002] At present, the treatment methods of municipal solid waste mainly include landfill, composting and incineration. Among them, the incineration technology has a high degree of volume reduction, volume reduction and harmlessness for waste incineration. The heat generated during the incineration process is used to generate electricity, which can realize the energy conversion of waste. It is a better waste disposal method. [0003] In the existing garbage pyrolysis method, during the pyrolysis process, due to the high water content of some garbage, the pyrolysis is not complete and residues appear, resulting in a longer time for pyrolysis, and the gas produced at the same time Contains a large amount of incineration particles, which is not conducive to the treatment of the subsequent exhaust gas treatment ...
