Waste smoldering combustion pyrolysis device with automatic controlling and monitoring function

Abstract

The invention discloses a waste smoldering combustion pyrolysis device with an automatic controlling and monitoring function. The waste smoldering combustion pyrolysis device comprises control monitoring equipment and one or more smoldering combustion pyrolysis equipment; each smoldering combustion pyrolysis equipment comprises a pyrolysis cylinder body and a sensing detection system, wherein an opening type feeding opening is formed in the top of the pyrolysis cylinder body, a vertically-arranged rotating shaft is rotationally connected in the opening type feeding opening through a supportingframe, the rotating shaft extends downwards to the lower part of the opening type feeding opening, and spiral extrusion blades are arranged on the part, at the lower part of the opening type feedingopening, of the rotating shaft; a slag discharging device is arranged at the bottom of the pyrolysis cylinder body; a plurality of gas suction sets are circumferentially arranged at the bottom of theside wall of the pyrolysis cylinder body, each gas suction set comprises an air inlet and an air outlet, an annular gas guide pipe is arranged in the pyrolysis cylinder body, and the air outlet is incommunication with the annular gas guide pipe; and a vent pipe is connected to the annular gas guide pipe, and the vent pipe is connected to a dust removal and cooling mechanism. The optimal smoldering combustion effect is achieved, and the running state and the target position of each smoldering combustion pyrolysis equipment can be realized through the control monitoring equipment.

Description

technical field [0001] The invention belongs to the technical field of urban garbage treatment, in particular to an automatic control and monitoring 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 soil, groundwater or the atmosphere, especially garbage The air odor around the treatment plant is serious, affecting the lives of surrounding residents. Chinese patent document CN207797070U discloses a micro-medium-pressure smoldering treatment system for oily waste, which mainly separates the gas-liquid two-phase through the gas-liquid cyclone separator; cools the steam through the cooler to improve the gas-liquid separation efficiency; The device reduces the emission of harmful gases such as sulfur and nitrogen, and achieves the purpose of...

AI Technical Summary

Problems solved by technology

The overall equipment operation of the above two smoldering treatment methods is complicated, the waste treatment efficiency is not high, there is no additional product output after treatment, and the useful components in the garbage are not fully utilized. There is no system or device for smoldering treatment of dry solid waste in cities and towns.
