Garbage microwave pyrolysis comprehensive treatment system and method and equipment used by same

Abstract

The invention discloses a garbage microwave pyrolysis comprehensive treatment system and a method and equipment used by the same, aiming to solve the problems of microwave pyrolysis treatment, and the method and equipment used by the system. The comprehensive treatment system comprises a municipal solid waste (MSW) preprocessing system A, a vertical garbage continuous microwave heating low temperature cracking furnace B, a solid product activated carbon production system C, a pyrolysis gas preparation fuel gas system D, a liquid product distilled extraction light oil and fuel oil system F and a matched sewage treatment system G, wherein the MSW preprocessing system A, the solid product activated carbon production system C and the pyrolysis gas preparation fuel gas system D are respectively connected with the vertical garbage continuous microwave heating low temperature cracking furnace B; and the liquid product distilled extraction light oil and fuel oil system F is connected with the oil recovery pipeline of the pyrolysis gas preparation fuel gas system D. The invention has the advantage that: low carbon emission is realized in the treatment process under the reducing atmosphere, fixed carbon in the garbage is emitted without violent toxicity like dioxin and heavy metal solid powder, the treated wastewater can be recycled and max garbage resource recycling is realized.

Description

Technical field [0001] The invention belongs to garbage treatment in the environmental protection industry, and in particular relates to a garbage microwave cracking treatment system and a vertical garbage continuous microwave heating low-temperature cracking furnace B used in the system, a solid product production activated carbon system C, a cracking steam preparation fuel steam system D, Liquid Product Distillation Extraction Method and Apparatus for Light Oil and Fuel Oil System F. Background technique [0002] 1. The main treatment methods of municipal solid waste [0003] The harmless methods of municipal solid waste mainly include sanitary landfill method, incineration method, composting method and resource comprehensive treatment method. According to the 2008 China Statistical Yearbook, as of the end of 2007, according to the statistical analysis of the volume of clearing and transportation, the proportions of landfill, composting and incineration for harmless treat...

AI Technical Summary

Problems solved by technology

[0016] (2) With the increase in the construction of garbage sanitary landfills, the problem of leachate treatment becomes more and more prominent

However, due to the complexity of garbage components and the variability over time and space, various forms of secondary pollutants will be produced during the incineration process, and some pollutants are even more harmful to the environment and ecology than the garbage itself.
