Embodiment Construction

[0021] (1) The lumpy fly ash that has been stably solidified but unqualified is collected from the ground by the bucket into the bucket for screening and crushing, and then is weighed by the electronic weighing set at the boom of the loading bucket and then fed into the mixing system. The tank weighs 487kg. After the fly ash feeding is completed, the on-board PLC automatically calculates the theoretical amount of the chelating agent diluent added according to the feeding amount, the weight is about 163kg, and automatically turns on the chelating agent diluent electronic pump to start adding the chelating agent diluent to the stirring tank.

[0022] The fly ash and chelating agent are stirred for 1.5 minutes in the stirring tank. After the stirring is completed, lower the stirring tank to the low position, and at the same time move the stirring lever to the discharge position, and the material in the stirring tank will be pushed to the discharge port by the spiral stirring blad...

Abstract

The invention discloses mobile emergency solidification and stabilization equipment for household garbage incineration fly ash, relates to novel technology development and application in the field of garbage incineration fly ash comprehensive stabilization treatment, and belongs to the technical field of hazardous waste treatment and disposal. The technology development and application of the equipment can realize stabilization treatment of (1) stable solidified and unqualified blocky fly ash needing secondary treatment, (2) flue gas system absorption tower hardened fly ash, (3) absorption tower peeled hardened fly ash, (4) scattered stacking of fly ash in original stock in a factory, and (5) heavy metal-containing waste residues and the like. Meanwhile, the equipment can be used as an emergency standby of a fixed fly ash stabilizing treatment system of a waste incineration power plant. The main technological process of the equipment comprises the steps of collecting, screening, crushing, quantitatively weighing, metering, dosing, stirring and discharging. The system flexibly moves along with a vehicle, a whole set of fly ash solidification and stabilization treatment process can be completed on one device, and meanwhile stabilization treatment of fly ash of various characters and waste residues containing heavy metal is achieved.

Description

Technical field: [0001] The technology relates to a comprehensive stabilization treatment technology for waste incineration fly ash, which belongs to the technical field of hazardous waste treatment and disposal. Background technique: [0002] At present, domestic conventional fly ash stabilization treatment mainly adopts on-site installation and fixed system equipment: after the fly ash enters the fly ash silo, it is transported to a separate weighing scale for measurement by a screw, and the solid agent is transported to a separate weighing scale for measurement by a screw, and the chelating agent is pumped to the In a separate weighing scale, the three substances are metered into a double-shaft mixer for mixing, and the solidified fly ash after unloading meets the relevant national standards before being bagged. [0003] The existing fixed fly ash processing system is directly connected to the ash bin through screw conveying, and can only process the fly ash in the ash bi...
