Energy-efficient indirect thermal desorption carbonization device and treatment method thereof

Abstract

The invention belongs to the technical field of organic solid waste treatment, and particularly relates to an energy-efficient indirect thermal desorption carbonization device and a treatment method thereof. The carbonization device comprises a preheating feed system and a material heating system, wherein the preheating feed system comprises a heat-exchange-jacket-bearing spiral feeder and a chimney pipeline; the material heating system comprises a heating furnace, a first resolution chamber and a second resolution chamber; the first resolution chamber and second resolution chamber respectively comprise a feed end aggregate hood, a discharge end aggregate hood and a silicon-carbide-lined refractory steel cylinder; and a first rotatable screw conveyer and a second rotatable screw conveyer are correspondingly arranged inside the refractory steel cylinders of the first resolution chamber and second resolution chamber. The carbonization device can solve the problems of high deformation tendency, high abrasion tendency and low corrosion resistance in the chamber pipe wall and the problem of incomplete combustion of noncondensable gas. The carbonization device can remove inorganic carbon in the overproof solid-phase residues to implement further decrement, lower the heat consumption of indirect thermal desorption equipment and reduce the residue landfill disposition cost.

Description

technical field [0001] The invention belongs to the technical field of organic solid waste treatment, and in particular relates to a high-efficiency and energy-saving indirect thermal desorption carbonization device and a treatment method that can extract, separate, reduce and reuse reusable energy in solid waste. Background technique [0002] In most cities in my country, municipal solid waste, medical waste, and waste plastics are treated by incineration, that is, high-temperature heat treatment, and many small hospitals use small incinerators. This method has insufficient fuel during incineration, etc. Many problems have caused these solid wastes to be incompletely burned, and highly toxic dioxins are easily produced, causing great harm to people's health. Under such conditions, it is difficult to achieve harmless waste, reduction, and recycling of waste. In addition, when hazardous waste is incinerated, it is often necessary to add fuel directly, which will increase the ...
