Abstract

The invention discloses a garbage smoldering pyrolysis device, and belongs to the technical field of urban garbage treatment. The device comprises a pyrolysis barrel body, wherein an opening type feeding port is formed in the top of the pyrolysis barrel body, a rotating shaft which is vertically arranged is rotationally connected in the opening type feeding port through a supporting frame, the rotating shaft extends downwards to the lower part of the opening type feeding port, a spiral extrusion blade is arranged at the part, below the opening type feeding port, of the rotating shaft, a slag discharge device is arranged at the bottom of the pyrolysis barrel body, a carbon slag processor is assembled at a slag outlet of the slag discharge device, a plurality of air suction sets are arrangedat the bottom of the side wall of the pyrolysis barrel body in the peripherical direction, the air suction sets comprise air inlets and air outlets, an annular air guide pipe is arranged on the pyrolysis barrel body, each air outlet communicates with the annular air guide pipe, a vent pipe is connected to the annular air guide pipe, and the vent pipe is connected with a dust removal and cooling mechanism. According to the garbage smoldering pyrolysis device, the effects that smoldering is sufficient, the efficiency is high, and products capable of being extracted after smoldering are more.

Description

Technical field [0001] The invention belongs to the technical field of urban garbage treatment, and particularly relates to a garbage smoldering pyrolysis device. Background technique [0002] Urban waste is mainly solid waste with a moisture content of about 20% after sorting and drying. At present, urban waste is mostly treated by incinerators, high-temperature pyrolysis devices or landfills, which will pollute the soil, groundwater or atmosphere, especially waste disposal The odor of the air around the plant is serious, affecting the lives of surrounding residents. Chinese patent document CN207797070U discloses a micro-medium pressure smoldering treatment system for oily garbage, which mainly separates gas and liquid two phases through a gas-liquid cyclone separator; cools steam through a cooler to improve gas-liquid separation efficiency; through desulfurization and denitration reactions The device reduces the emission of harmful gases such as sulfur and nitrogen, and achiev...
