[0002] Fly ash from the incineration of municipal solid waste is a by-product of the production process of municipal solid waste incineration power plants. Because it contains a certain concentration of dioxins and heavy metals, it is listed as a hazardous waste in the "National List of Hazardous Wastes". At present, the main methods for the treatment and disposal of fly ash in municipal solid waste incineration power plants include: 1) After being stabilized and cured in the plant, it meets the admission requirements of the "Standards for Pollution Control of Municipal Solid Waste Landfill" for fly ash from the incineration of municipal solid waste, and then is landfilled in a separate area of ​​the municipal solid waste sanitary landfill. At present, there are also some new technologies for the treatment and disposal of fly ash, such as ex-situ high-temperature melting and sintering;

[0003] For the sintering process of fly ash, the current fly ash discharge port is opened at the inner top of the furnace body. In this way, after the fly ash enters the furnace body, it is in the form of small particles and powder when it enters the incinerator. Some fly ash is easily suspended in the furnace due to the influence of hot air. The overall sintering of the fly ash is uneven, and during the discharge process, since the discharge port is always in an open state, there is also the situation where waste gas is discharged to the surrounding area.
