Abstract

The invention discloses the treatment technology for biomass solid waste and hazardous waste. Materials are sequentially subjected to pretreatment, loading, pyrolysis and gasification, and combustion and steam making, and the generated tail gas is subjected to the fuel gas treatment. The combustion temperature of a pyrolysis and gasification furnace is controlled at 700-900 DEG.C when the pyrolysis and gasification furnace treats the solid waste such as mushroom dregs, so that a problem that a static bed is liable to coke is avoided. The whole operation is performed in the reduction environment, NOx can be effectively prevented from generating, the disturbance of the materials in the whole bed is high, and the whole gas output and the factor of created gas are stable. Waste liquid and ash output by a pyrolysis and gasification bed can be fully combusted and burned out through the fuel gas output by the pyrolysis and gasification bed, so that carbon residue in the ash can be further reduced, and the waste liquid can be thoroughly eliminated. A bubbling fluidized bed combustion tower employs pyrolysis and gasification bed ash as the bed material, and the fluidization of the materials in the furnace can be promoted after the air enters the combustion tower.

Description

technical field [0001] The invention relates to the technical field of a biomass resource utilization system applicable to a pyrolysis gasification process, in particular to a biomass solid waste and hazardous waste treatment process. Background technique [0002] Biomass waste is the waste produced by human beings in the process of utilizing biomass production and consumption. Its traditional treatment methods include landfill and incineration, but it needs to occupy a large amount of land, and it is easy to cause secondary pollution, especially some hazardous waste. [0003] At present, my country's biomass waste has the characteristics of large production volume and high content of degradable organic matter. If it can be used effectively, it will not only reduce pollution, but also help alleviate the current situation of my country's energy shortage. Contents of the invention [0004] In view of this, the present invention provides a biomass solid waste and hazardous w...
