Automatic control domestic garbage pyrolysis gasification furnace

Abstract

The invention discloses an automatic control domestic garbage pyrolysis gasification furnace, and belongs to the technical field of domestic garbage recycling. The automatic control domestic garbage pyrolysis gasification furnace comprises a furnace base, a furnace, a material distribution device, an air supply device, an air distribution disc driving device and a combustible gas and oil gas backflow device. The automatic control domestic garbage pyrolysis gasification furnace has the advantages that the automatic control domestic garbage pyrolysis gasification furnace comprises fireproof heat-insulation walls, accordingly, the internal gasification temperatures of the automatic control domestic garbage pyrolysis gasification furnace can be increased, and the gasification efficiency can beimproved; a large quantity of generated tar can be secondarily cracked by the aid of the combustible gas and oil gas backflow device, accordingly, the combustible gas gasification quality and puritycan be improved, and the combustible gas gasification quantity can be increased; the heights of material layers in the automatic control domestic garbage pyrolysis gasification furnace can be accurately controlled by a fixed-point material distributor, and accordingly gasification effects can be guaranteed; the fixed-point material distributor and material feeders are in interlocking control, accordingly, the automatic control domestic garbage pyrolysis gasification furnace can be conveniently operated by personnel, and unnecessary motor power consumption can be reduced; support structures arearranged at a furnace bottom in a flange manner, accordingly, all components are convenient to detach and maintain, and residues and water can be separated from one another; the structures of air supply systems are simplified, accordingly, mounting can be facilitated, the automatic control domestic garbage pyrolysis gasification furnace has functions of two gas channels, and water does not need to be periodically supplemented for water seals; the residues can be discharged and collected in a concentrated manner by the aid of an automatic residue discharge device at any time; anti-explosion valves are arranged on the upper portion of the furnace, and accordingly harm on equipment and the personnel due to sudden flash explosion of gas can be prevented.

Description

technical field [0001] The invention relates to an automatic control domestic waste pyrolysis gasification furnace, which belongs to the technical field of domestic waste resource utilization. Background technique [0002] At present, waste pyrolysis gasification technology and treatment equipment are the most advanced, economical and practical process methods actively advocated by domestic and foreign countries, especially developed countries, which can not only achieve thorough waste reduction, complete harmless treatment, and resource utilization Maximization, and no secondary tail gas emission pollution, no harmful waste residue discharge, etc. There are three main methods of waste disposal: landfill, incineration and composting. The incineration method is a method in which the garbage is placed in a high-temperature furnace to fully oxidize the combustible components, and the heat generated is used for power generation and heating. The advantage of incineration treatm...

AI Technical Summary

Problems solved by technology

The advantage of incineration treatment is that it has a good reduction effect (the volume of the residue after incineration is reduced by more than 90%, and the weight is reduced by more than 85%). Both structures) will have relatively low internal temperature of the gasifier, high tar content in the gas after gasification, unclear state of the material layer in the furnace, water-sealed structure of the furnace body that makes it difficult to discharge slag due to ash and slag mixing, and water-sealed structure of the air supply pipeline complex problems exist
