Purification treatment method and apparatus of solid waste pyrolysis gasification synthesis gas

Abstract

The invention relates to a purification treatment method and apparatus of a solid waste pyrolysis gasification synthesis gas, and belongs to the technical field of pollutant emission control. The apparatus applies a three-phase alternating current arc plasma torch to purify and treat a synthesis gas generated by a treatment process of solid waste pyrolysis gasification and the like. In the apparatus, a gas to be treated is subjected to expansion and deceleration, a reaction residence time is increased, the thorough mixing of the gas to be treated with a high temperature plasma in a reaction chamber is increased, a uniform high-temperature region and a controlled atmosphere formed by a circumferential uniform distribution manner of a three-phase alternating current plasma are utilized, under the action of the high temperature plasma, tar, dioxin and other macromolecular organic substances containing in the gas to be treated are directly decomposed into small molecular chain hydrocarbonswithout combustion, and thus the synthesis gas purification function is achieved under conditions that combustible components in the synthesis gas are not burned.

Description

technical field [0001] The invention relates to a solid waste pyrolysis gasification synthesis gas purification treatment method and device, belonging to the technical field of pollutant emission control. Background technique [0002] As the environmental protection concept of "lucid waters and lush mountains are golden mountains and silver mountains" has become the consensus of the whole people, protecting the environment and reducing pollution emissions have become the focus and topic of concern of the whole people. At present, the treatment of solid waste in my country is gradually shifting from traditional landfilling to Mainly solid waste pyrolysis gasification, incineration and other treatment technologies, these technologies play an important role in the "reduction, harmless, resourceful" disposal of waste. However, these treatment technologies have more or less secondary pollution risks of pollutant discharge, and the defects of these technologies have increasingly at...

Problems solved by technology

This has resulted in a more cumbersome purification process after the pyrolysis and gasification of solid waste. Moreover, by setting up an additional combustion chamber, the dioxins, polycyclic aromatic hydrocarbons, and polychlorinated hydrocarbons in the synthesis gas are removed. At the same time as macromolecular organic compounds such as biphenyl, CH in syngas 4 , CO and other active ingredients are burned
