Abstract

The invention relates to the technical field of garbage disposal, in particular to a household garbage pyrolytic electricity generation method. The method comprises the following steps that S1, household garbage is conveyed into a pyrolytic gas making furnace for pyrolytic gasification, reaction gas is introduced into the pyrolytic gas making furnace, and a product which contains combustible gas is obtained, wherein the oxygen content in the reaction gas ranges from 30% to 93%; S2, the heat value of the generated combustible gas is detected, and the oxygen content in the reaction gas introduced into the pyrolytic gas making furnace is regulated in real time, so that the heat value of the obtained combustible gas is output stably; S3, the combustible gas obtained in S2 is conveyed into a gas electricity generator for electricity generation. The gas obtained through household garbage pyrolytic gasification can be directly used for gas electricity generation.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a method for generating electricity by pyrolyzing domestic garbage. Background technique [0002] With the development of society, the increase of population and the improvement of people's living standards, the output of domestic waste is constantly increasing, and the composition of domestic waste is becoming more and more complex, which will pollute the environment and endanger people's health more and more seriously. If domestic garbage is directly incinerated, a large amount of polluting gas will be emitted, which will aggravate the harm to the environment. Now people's daily life electricity mostly relies on thermal power generation, which consumes a lot of energy. In order to solve the problems of domestic waste disposal and energy, a technology has been developed to generate combustible gas by pyrolysis and gasification of domestic waste, and use these combusti...
