Device and method for harmless treatment of rural garbage

Abstract

The invention relates to the field of garbage disposal, in particular to a device and method for harmless treatment of rural garbage. The device comprises a pyrolysis gasification area and a combustion area, wherein the combustion area comprises a plurality of combustion chambers; the lower part of the pyrolysis gasification area is communicated with all the combustion chambers in sequence in an increasing height manner; a public side wall of two adjacent combustion chambers is provided with a combustor; and each combustor comprises a shell and an oxygen guide pipe. The method comprises the steps of: stacking combustible garbage in a closed environment to combust the combustible garbage locally; carrying out pyrolysis gasification on the garbage by using heat generated through combustion to generate combustible gas; and importing the generated combustible gas and powder into the plurality of combustors for aerobic combustion, and settling powder imported in the combustors at the same time. Compared with the prior art, the device and the method for the harmless treatment of the rural garbage, provided by the invention, can be used to decompose organic matters more completely in manners of pyrolysis gasification and multi-stage combustion, so that a harmless purpose is achieved.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a device and method for harmless treatment of rural garbage. Background technique [0002] With the acceleration of my country's new rural construction, the rural population has changed from relatively scattered to relatively concentrated, and how to properly dispose of the generated garbage has become a current problem. Because rural garbage is relatively scattered, difficult to collect, and has a long transportation distance, the overall coverage of garbage collection and transportation will lead to high transportation costs; at present, my country's rural areas lack relatively low investment costs and operating costs, and effective treatment Garbage technology and equipment; because the garbage collection and transportation system cannot meet the full coverage of scattered points and remote rural garbage, traditional methods mostly use the original stacking and simple landfill ...

AI Technical Summary

Problems solved by technology

[0004] However, due to the insufficient combustion of garbage in the direct incineration process, many garbage will produce a large amount of harmful gas during the heating process, and this part of the gas will be directly discharged into the atmosphere after being produced, seriously affecting the atmospheric environment; in addition, due to insufficient oxygen content inside the garbage, it cannot Support the full combustion of garbage, so it is necessary to turn over and stir the garbage during the incineration process to make it fully mixed with oxygen to improve combustion efficiency

However, this method will generate a large amount of dust, and the garbage will generate a strong updraft during the combustion process, which will bring the dust in the garbage into the atmosphere, further aggravating the pollution of the atmospheric environment.
