The invention discloses a distributed fly ash high-temperature melting vitrification utilization system which comprises a vortex combustion chamber, a burnout chamber, a hearth and a waste heat recovery system which are sequentially arranged. The vortex combustion chamber is used for receiving combustion materials of fly ash and is directly connected with a fly ash trapping device on the site of a waste incineration power plant through a conveying pipeline. Flue gas cooled by the waste heat recovery system is led to a flue gas treatment device on the site of the waste incineration power plant. The problems that in the incineration fly ash high-temperature melting process, the treatment process is complex, fuel consumption is large, vitrification is not thorough, and economical efficiency is poor are solved. The invention further discloses a method through which incineration fly ash is directly and pneumatically conveyed to the high-temperature melting vitrification device. Integrated operation of the melting technology and a waste incineration power plant is achieved, the whole system forms closed circulation, no extra outward transportation landfill is needed, only glass slag formed by the system can be subjected to resource utilization, and zero-landfill green treatment of waste is really realized.
Description
technical field [0001] The invention relates to the technical field of high-temperature melting vitrification, in particular to a system and method for utilizing distributed fly ash high-temperature melting vitrification. Background technique [0002] With the rapid development of the economy, the urban waste is also increasing continuously. At present, the urban domestic waste in our country is increasing at a rate of 8% to 10% per year. As the calorific value of municipal solid waste increases year by year and the output continues to increase, many cities in our country have adopted the incineration method to deal with municipal solid waste. After domestic waste is incinerated, mineral elements and various harmful elements are concentrated in the incineration ash, and the content of toxic elements is 10 to 100 times higher than that of ordinary soil, and the waste incineration ash contains high concentrations of dioxins "National Hazardous Waste The Inventory has clearly ...
