Abstract

The invention provides a method for producing gas by oxygen enrichment and thermolysis of organic solid wastes. The organic solid wastes take enriched oxygen and water vapor as gasified media in a gasification furnace; in the anoxic atmosphere, part of organic solid wastes are subjected to anoxic combustion to provide heat, wherein one part of heat is used as a hot source for generating water vapor and the other part of heat is used for gasifying residual substances to generate gasification gas; the gasification gas whirls in a high-temperature furnace body, stays for over 3s and can be used for effectively decomposing contaminants. The gasification gas is subjected to high-temperature catalytic reforming before entering a gasification gas outlet; alkaline matters are sprayed in a gasification gas outlet pipeline; and finally, the gasification gas enters a dust collector cyclone for desorbing solid particles. Compared with other thermal transition systems, the method can be used for realizing the secondary pollution-free emission, has high quality of converted products and a wide application prospect and is suitable for large-scale popularization and application.

Description

technical field

[0001] The invention relates to the technical field of organic solid waste treatment, in particular to a method for producing gas by oxygen-enriched pyrolysis of organic solid waste. technical background

[0002] Environmental issues are one of the important factors that determine human survival and development. Since the industrial revolution, the degree of industrialization in the world has been increasing day by day. With the development of production scale and society, a large amount of waste has been produced, especially in cities. Moreover, the urbanization of countries in the world is developing rapidly. In 2008, the urban population surpassed the rural population for the first time, reaching nearly 3.4 billion. The further increase of urban population density has led to an increasingly serious problem of urban solid waste.

[0003] China is now the center of the world's manufacturing industry. The existing factories in the country are located in or ...
