Background
Relevant data in 2017 show that the average of China produces 09-1.2Kg of urban domestic garbage per person every day, and the urban domestic garbage still increases at a rate of 3-5% every year. Nearly 100 hundred million tons of various urban garbage are discharged in the world every year. These wastes occupy a large amount of land, destroy urban landscapes and even cause persistent environmental pollution, and become a serious and urgent challenge to people in new generations.
At present, the reduction, reclamation and harmless treatment modes of urban domestic garbage mainly comprise three treatment modes of landfill, composting and incineration. Wherein the sanitary landfill and the pyrolysis treatment are the main modes of the urban garbage resource treatment in China. However, under the conditions that site selection is increasingly difficult and the landfill cost is continuously increased, the domestic garbage sanitary landfill is in a bottleneck period. The pyrolysis treatment of the municipal solid waste has attracted more attention of people in the environmental protection industry.
The general domestic garbage has high water content and low heat value, is difficult to directly pyrolyze and carbonize, and increases the operation cost if auxiliary fuel is added for combustion supporting. Tests show that when the moisture content of the household garbage is reduced from 60% to 40%, the heat value of the garbage is increased from 1250Kcal/kg to 2150Kcal/kg, so that the household garbage is greatly promoted to be subjected to stable pyrolysis, and the pyrolysis carbonization (or pyrolysis gasification) rate of the household garbage is improved.
