The fly ash treatment technology at present mainly comprises high-temperature treatment and low-temperature treatment, wherein the high-temperature treatment comprises melting and sintering, and the low-temperature treatment comprises solidification and medicament treatment. In order to improve the treatment efficiency and reduce pollution, waste incineration power plants often adopt low-temperature treatment, and the low-temperature treatment of fly ash mainly comprises a cement solidification method, a chelating agent stabilization method and a cement and chelating agent synergistic treatment method. The cement and chelating agent synergistic treatment method (also called fly ash solidification and stabilization method) is a new combined process based on the cement solidification method and the chelating agent stabilization method, and is widely applied to the current waste incineration fly ash treatment.
The fly ash of the waste incineration power plant comes from tail flue gas purification equipment and is about 3% -5% of the waste treatment capacity. Fly ash is stored in a fly ash bin firstly and then is conveyed to solidification and stabilization equipment for treatment, the working time of the fly ash solidification and stabilization treatment is generally required to be 8 h/day, and the fly ash when not working at night is stored in the fly ash bin.

At this stage, a classical scheme is: a set of independent fly ash storage device and a set of fly ash pneumatic conveying device are arranged in the main plant, and a set of independent fly ash solidification stabilizing device is arranged outside the main plant. The fly ash is conveyed from the fly ash storage device to a solidification stabilization workshop by a pneumatic conveying device for treatment. Only flying dust storage storehouse in this scheme main building, area is little, and the chelation solidification is favorable to clean and tidy in the main building outside the factory building, but need dispose pneumatic conveyor and be independent of the solidification stabilization workshop of main building, and investment cost is high. Another classical solution is to place both the fly ash storage device and the solidification stabilization device in the main building. And a steel frame is additionally arranged beside the fly ash storage device and used for installing a solidification and stabilization device and conveying the fly ash to solidification and stabilization equipment through a screw. In this scheme, a fly ash storage steel frame corresponds to a solidification stabilization steel frame. For the project with smaller garbage disposal scale, the requirement of daily disposal capacity of the fly ash can be met by arranging a fly ash storage device and a solidification and stabilization device. However, for the project with large garbage disposal scale, two fly ash storage devices and two fly ash solidification and stabilization devices are usually required to meet the requirement of daily disposal of fly ash. Therefore, not only the equipment is various, but also the occupied area is large. The technical scheme is difficult to implement for projects with large daily treatment capacity and tense land area.
