After the fly ash from the flue gas treatment system of the incineration plant is sent to the storage bin, it is quantitatively conveyed to the screw conveyor, and then sent to the chelation mixing device by the screw conveyor, and the cement in the cement silo is also quantitatively conveyed to the screw conveyor below it. , is also sent to the chelation mixing device by the screw machine, and the fly ash and cement are mixed in the chelation mixing device according to the designed ratio. At the same time, the chelation agent dilution pump and the water supply system are started simultaneously to supply chelation agent and water. Fly ash, cement, chelation agent and water are mixed in the chelation mixing device, and the heavy metals in the fly ash react with the chelation agent to form chelation compounds to be stabilized.
Fly ash stabilization treatment equipment The stabilized fly ash and cement slurry from the chelation mixing device are finally made into cement bricks through belt conveyors, pallet conveyors, block forming machines, and block conveying devices. Afterwards, it is maintained in the maintenance room. During the maintenance process, a large amount of water evaporates, and then it is transported away by a special brick truck.
