Cracking technology and system of solid organic material

Abstract

The invention provides a cracking technology of a solid organic material. The technology comprises the following steps: heating a gas medium to 200-800 DEG C, continuously introducing the heated gas medium to a cracking device, and cracking the solid organic material under the common action of the heated gaseous medium and microwaves, wherein the gas medium is anyone or a combination comprising above one of nitrogen, water vapor, carbon dioxide and inert gas. The technology aims at the particularity of the solid organic material, innovatively combines treatment of gas obtained after cracking of the solid organic material with microwave cracking, and improves the controllability of the cracking treatment process through adopting specific technologic steps and parameters to substantively reduce the energy consumption and substantively improve the cracking efficiency.

Description

technical field [0001] The invention relates to a processing technology for cracking solid organic materials, in particular to a cracking process and system for solid organic materials, and belongs to the technical field of waste treatment and resource utilization. Background technique [0002] The disposal of solid organic materials (municipal waste, medical waste, biomass, plastic) has become a worldwide problem. The existing treatment methods mainly include landfill method, compost method and incineration method. Although each has its own advantages, the disadvantages are also very obvious. The landfill method pollutes the environment, occupies a large amount of land resources, and gradually reduces its applicable value. The composting process is difficult to control, the secondary pollution to the environment is large, the utilization of organic matter is incomplete, the fertilizer composition is complex, and the reduction is small, and other factors will be gradually e...
