Device and method of solid waste thermal pyrolysis-plasma reforming

Abstract

The invention relates to a device and method of solid waste thermal pyrolysis-plasma reforming. The device comprises a pyrolyzing furnace and a plasma reforming device, wherein the gas outlet of the pyrolyzing furnace and the gas inlet of the plasma reforming device are connected through a gas guide pipe; a feed opening is formed in the top of the pyrolyzing furnace, and a gas outlet is formed inthe upper part of the side wall of the furnace body; a pyrolyzing furnace wall, a pyrolyzing furnace outer flame retarding material, a pyrolyzing furnace inner flame retarding material and a materialsteel cylinder are arranged on the side wall of the pyrolyzing furnace from outside to inside; the gas inlet of the plasma reforming device is positioned at the center of one side wall of the device,and the gas outlet is positioned at the center of the side wall opposite to the gas inlet; 1-4 plasma torches are distributed on plasma torque assembly points which are selected on other wall faces except the wall faces with the gas inlet and gas outlet; and by adopting the plasma technology, multiple compound pollutants in smoke can be can be efficiently removed, including gaseous pollutants, solid and liquid particles, and the reforming technology cannot generate secondary pollution. The device has small equipment size and simple operation.

Description

technical field [0001] The invention relates to a solid waste pyrolysis gasification-plasma reforming device and method, in particular to provide a plasma technology compound pollutant purification device and method, belonging to the technical field of environmental protection. Background technique [0002] Pyrolysis is the process of converting solid waste such as domestic garbage, agricultural and forestry waste, organic waste and petroleum sludge generated in industrial activities into combustible gas under anaerobic conditions, and has a wide application prospect. The combustible gas obtained through the pyrolysis process of solid waste can be used for direct combustion in gas turbines or gas engines, for fuel cells, as industrial gas, and for other industrial production, etc. [0003] The gaseous substance produced by pyrolysis has a very complex composition and is a compound pollutant integrating solid, liquid and gaseous pollutants. The solid components mainly includ...

AI Technical Summary

Problems solved by technology

The biological method has low investment and operating costs, but the operation is complex and occupies a large area, and there is a possibility of secondary pollution

[0005] Therefore, the current pyrolysis technology has the following problems: the gas produced by pyrolysis has complex components and contains macromolecular substances such as tar, which needs to be purified before subsequent use; conventional purification methods such as adsorption, catalytic combustion, or biological methods have many deficiencies
