Solid organic waste gasification and melting cycle-treatment process

Abstract

The invention relates to a solid organic waste gasification and melting cycle-treatment process, which comprises steps of crushing, anhydration, moulding, gasification and melting. A gasification product is mainly combustible gas and pyrolytic carbon, and the pyrolytic carbon undergoes melting treatment. The use of the combustible gas is mainly divided into two parts: most of the combustible gas is conveyed into a secondary combustion chamber to be combusted to heat an anhydration medium so as to provide energy for the anhydration phase or power an internal combustion engine; and part of the combustible gas is sent into a melting furnace and oxygen-enriched air or pure oxygen is added to melt the pyrolytic carbon, and generated flue gas is sent into the secondary combustion chamber. Tail gas generated during the phases of organic waste storage, crushing, anhydration and moulding is also sent into the secondary combustion chamber to be used as combustion air for high-temperature combustion treatment. By the technology for treatment of various solid organic wastes such as municipal domestic waste, industrial refuse, various livestock residues, sludge, straw and the like, quantitative reduction is obvious, and the technology has characteristics of energy conservation and emission reduction, low-carbon and environmental protection, less secondary pollution, high harmless degree, low operation cost and remarkable environmental benefit and the like.

Description

technical field [0001] The invention relates to an organic waste gasification treatment process, in particular to a solid organic waste gasification melting cycle treatment process, which belongs to the field of organic waste treatment process. Background technique [0002] With the rapid development of the economy, more and more wastes are produced by human production and life. Taking domestic waste as an example, the amount produced every year is increasing at a rate of 8% to 10%. Serious harm to the ecological environment. [0003] The treatment of solid waste generally goes through a process of landfill, composting, and incineration. In my country, landfill and incineration are still the main methods at present, but these two methods have different degrees of potential safety hazards. The landfill method not only occupies a large amount of land, but also has the risk of harmful substances in the waste permeating into groundwater resources, which may cause soil or water ...
