A kind of cracking method and system of solid organic material

Abstract

The invention provides a solid organic material cracking method and system. The method comprises the following steps of: A, pre-treating a solid organic material; B, sending the pre-treated solid organic material into a cracking device; C, heating a gas medium to 350-700 DEG C; D, continuously importing the heated gas medium into the cracking device to act on the solid organic material with microwave, so as to carry out cracking to obtain a solid product and a mixed gaseous product; and E, importing a part of the obtained mixed gaseous product into a gas heating device in the step C so as to heat the mixed gaseous product to 350-700 DEG C to be circularly used for the cracking in the step D. The process can effectively decrease the cracking energy consumption and the cracking time, and can save the cost.

Description

technical field [0001] The invention relates to a cracking treatment technology for solid organic materials, in particular to a cracking method 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, plastics) has become a worldwide problem. Existing treatment mainly contains landfill method, composting method and incineration method, although each has its own advantages, its disadvantages are also very obvious. The landfill method pollutes the environment, occupies a large amount of land resources, and its applicable value gradually decreases. Composting method The composting process is difficult to control, the secondary pollution to the environment is large, and the utilization of organic matter is incomplete, the composition of the fertilizer is complex, and the reduction is small, and other facto...
