Abstract

The invention relates to a method and equipment for preparing fuel from household garbage for suppressing dioxin. The method comprises the following steps of: introducing a heat source into vertical heat treatment equipment by using high-temperature gas as the heat source to ensure that the heat source is in direct contact with the household garbage in the vertical heat treatment equipment to cause heat transfer; performing thermal cracking reaction after the raw materials are heated; recovering and utilizing the cracked gas phase product; burning out residues caused by thermal cracking; and introducing high-temperature smoke gas generated by burning into the heat treatment equipment to heat the raw materials. The equipment for preparing the fuel from the household garbage for suppressing dioxin provided by the invention mainly comprises the vertical heat treatment equipment for drying the household garbage and performing thermal cracking on the household garbage, equipment for burning the cracked residues and collection and utilization equipment for the gas phase product. The method and the equipment have the advantages that equipment structure is simple, large-scale, continuity, reclamation and minimization treatment of the household garbage can be realized, and the like.

Description

technical field

[0001] The present invention relates to a method and equipment for producing fuel from domestic waste that curbs the generation of dioxin; specifically, it belongs to the direct contact heat transfer between domestic waste and high-temperature flue gas, and performs carbonization under anaerobic conditions to obtain fuel (fuel oil or / and Gas) method and apparatus. technical background

[0002] With the development of society and the improvement of people's living standards, the content of organic components in domestic garbage and garbage has been increasing, and has seriously harmed the living environment of human beings. Effectively disposing of these wastes to make them harmless and recyclable has become a subject of global attention and research.

[0003] The composition of domestic waste is complex, and the existing domestic waste (or including medical waste) heat treatment technology and equipment, such as gasification incineration method, direct incin...
