Description

Utilize integrative accuse dirty system of domestic waste gasification of U type reactor
Technical Field
The invention relates to the technical field of solid waste garbage gasification, in particular to a domestic garbage gasification integrated pollution control system utilizing a U-shaped reactor.
Background
The traditional garbage disposal methods mainly comprise a landfill method, a composting method and an incineration method. The direct landfill of the garbage can cause heavy metals, organic chemical pollutants and the like in the garbage leachate to permeate underground, pollute underground water resources and land resources and threaten the ecological environment and human health. The composting method can realize the resource utilization of garbage, but can generate ammonia gas, methane and other pollution, has higher danger, and simultaneously has the problems of long treatment time, small treatment amount, large occupied area and the like. Due to the complexity of the components of the household garbage and the incomplete classification of the garbage, the fertilizer efficiency of the garbage compost is far lower than that of a chemical fertilizer, and the actual utilization efficiency is lower. The incineration method can effectively convert chemical energy in the garbage into heat energy, but is limited by the problems of uneven heat value, insufficient combustion and the like, and meanwhile, dioxin generated by the incineration of the garbage and volatile heavy metals in fly ash can cause serious secondary pollution.
Gasification technology has received much attention because of its wide use, high energy utilization, excellent pollution control and other advantages. The domestic garbage gasification is a process of reacting organic components in the garbage with gasifying agents (oxygen, carbon dioxide, water vapor and the like) under a reducing atmosphere to generate combustible gas (hydrogen, carbon monoxide, methane and the like), tar and ash at a certain temperature, and the garbage which is not suitable for landfill and incineration can be well treated. The three-phase products of the domestic garbage gasification can be used as auxiliary fuel or chemical raw materials, so that the gasification technology is superior to the traditional incineration technology in the aspect of raw material utilization rate. The domestic garbage inevitably contains sulfur elements due to the complexity of the components, and is converted into gaseous sulfur pollutants during gasification; meanwhile, the gasification of the household garbage can also generate tar byproducts with high viscosity.
In the prior art, a sectional continuous treatment mode is adopted for treating gasified sulfur pollutants and tar, namely, sulfur fixing agent fixation and catalytic cracking are carried out on the sulfur pollutants and tar step by step. The method has the advantages of longer process flow, higher equipment investment and difficult control due to the multi-stage series connection. If a household garbage gasification system is designed, sulfur pollutants and tar are treated simultaneously when raw materials are gasified in a furnace, so that the treatment process is simplified, the equipment cost is reduced, and finally the reduction, the recycling and the harmless utilization of the household garbage are realized.
