Description

technical field [0001] The invention belongs to a garbage treatment device, in particular to a domestic garbage pyrolysis gasification device. Background technique [0002] At present, with the continuous development of the city, a large amount of domestic waste cannot be disposed of in time, which has become a public nuisance. In order to solve the domestic waste, the existing waste is mostly disposed of by burning in an incinerator: while the existing waste incineration There are the following problems and deficiencies in the treatment technology: 1. The construction investment of waste incinerator is high. Since my country's waste has not been classified and collected, most domestic waste has high moisture content and low calorific value. 2. The key technology and equipment depend on imports, and some major technical problems have not been solved, especially the circulating fluidized bed incinerator, which is still in the research and development stage in China; 3. The flue...
