Abstract

The invention discloses a household garbage pyrolysis, gasification and combustion integrated device which comprises a pyrolysis and gasification chamber, a secondary combustion chamber and a flue gas cooling chamber. A flue gas outlet of the pyrolysis and gasification chamber is communicated with a flue gas inlet of the secondary combustion chamber through a flue gas channel; and a flue gas outlet of the secondary combustion chamber is communicated with a flue gas inlet of the flue gas cooling chamber through a flue gas channel. By respectively controlling the ventilation quantity and the hearth temperature of two combustion chambers, the requirements of a two-section type pyrolysis, gasification and combustion process of carrying out anoxic combustion and pyrolysis gasification in the pyrolysis and gasification chamber and carrying out peroxy combustion in the secondary combustion chamber are met, so that garbage is fully burnt out, and the environmental protection requirement of eliminating secondary pollution is met. The secondary combustion chamber separates dust in the flue gas through gravity settling.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a device for integrating pyrolysis, gasification and combustion of domestic waste. Background technique [0002] Along with the improvement of people's material living standards, many incongruities have also appeared: some remote towns and cities have randomly piled up production and domestic waste, resulting in the front and back of farmers' houses becoming garbage dumps, and the farmland near their houses has also become garbage. Station, walking road is full of colorful garbage bags. According to the survey by the Ministry of Health, the amount of domestic waste generated by each person in cities and towns is currently 0.86 kilograms per day, and the annual domestic waste in cities and towns across the country is close to 300 million tons. It affects the living environment of farmers and threatens the governance of village public affairs. [0003] At present...
