Abstract

The invention relates to the field of gasification of waste and solid waste, in particular to a waste and solid waste gasifier, which comprises a gasifier body which is communicated with an oxygen supply unit and is used for enabling the waste and the solid waste with the calorific value higher than the set calorific value and a gasifying agent to have a gasification reaction, wherein the oxygen supply unit is used for supplying oxygen-enriched air or pure oxygen with concentration higher than the set concentration to the gasifier to be used as the gasifying agent so that the temperature of the gasification reaction is 120 to 2000 DEG C. In the waste and solid waste gasifier provided by the invention, the oxygen supply unit is used for supplying oxygen-enriched air or pure oxygen with concentration higher than the set concentration to the gasifier to be used as the gasifying agent so that the temperature of the gasification reaction is 120 to 2000 DEG C, the residual ash of the gasification reaction is liquid high-temperature residues in a molten state and discharged in a molten state, and the gasification reaction has good continuity and high stability.

Description

technical field [0001] The invention relates to the field of garbage and solid waste gasification, in particular to a garbage and solid waste gasification furnace. Background technique [0002] With the acceleration of urbanization and the increasing shortage of land resources, waste incineration technology has become one of the main means of dealing with domestic waste in large and medium-sized cities. [0003] At present, the incinerators used at home and abroad mainly include mechanical grate furnaces, fluidized bed incinerators and fixed bed incinerators. These incineration technologies need to use excess air as a combustion aid when dealing with domestic waste. The excess air system is very high, 1.5 to 1.8 for mechanical grate furnaces, 2.0 to 2.5 for fluidized bed incinerators, and higher for fixed bed incinerators. , reaching above 3.0. After incineration, each kilogram of garbage produces 6-15Nm3 waste gas, which requires a huge tail gas purification system for fl...
