Problems solved by technology

However, due to the characteristics of poor stability, low calorific value, and high moisture in urban waste, it is generally difficult to maintain the temperature at the incinerator outlet above 900 °C without sorting, and the amount of flue gas generated by waste incineration is large and cont

Abstract

The invention discloses a dry-process rotary cement kiln cooperative household garbage treatment system. The dry-process rotary cement kiln cooperative household garbage treatment system comprises a garbage pre-treatment system, a garbage incineration system, a flue gas purification system, a leachate treatment system, a cement clinker sintering system and a cement proportioning system. By using the dry-process rotary cement kiln cooperative household garbage treatment system disclosed by the invention for treating municipal domestic garbage, heat energy, ash, slag and leachate are completely utilized, and zero contaminant discharge is achieved during the whole treatment process; meanwhile, the generation of dioxin can also be effectively controlled and secondary pollution is avoided, thus realizing the requirements of 'reduction, resourcezation and harmlessness' of domestic garbage treatment.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a dry-process cement rotary kiln cooperative treatment system and a treatment method for domestic waste. Background technique [0002] With the improvement of people's living standards, the discharge of domestic waste is also increasing. At present, my country's municipal solid waste stockpile has reached 6 billion tons, occupying 500 million square meters of arable land, producing 200 million tons of municipal solid waste every year, and will grow rapidly at a rate of 9%. These large quantities of domestic waste have constituted an increasingly serious threat to the ecological environment in and around the city. [0003] Traditional garbage disposal methods include landfill, composting, and incineration. Urban garbage disposal in my country started relatively late, and at present it is mainly sanitary landfill. Although waste incineration and power plants have...
