Fly ash curing treatment system

Abstract

The invention provides a fly ash curing treatment system. Lots of dust-containing water vapor in a stirrer is effectively prevented from entering a weighing body to avoid material hardening on a weighing body discharge door and inside of the weighting body, the weighing precision is guaranteed, and normal blanking operation is guaranteed. The fly ash curing treatment system is characterized by comprising a fly ash weighing bin and an agent weighing bin, wherein a fly ash bin is connected with the fly ash weighing bin by virtue of a valve; an agent bin is connected with the agent weighing bin by virtue of a valve; the fly ash weighing bin and the agent weighing bin are respectively connected with a first stirrer by virtue of valves; and a mixed stirrer is connected with a second stirrer by virtue of the valve.

Description

technical field [0001] The invention relates to the technical field of environmental engineering waste incineration fly ash treatment, in particular to a fly ash solidification treatment system. Background technique [0002] The fly ash solidification and stabilization system refers to the dust collected by the flue gas purification system (reaction tower and bag filter). Because of its complex composition and a certain amount of toxic substances, it is treated separately from the slag produced by incineration, using chelating agents or inorganic The stabilized fly ash products are stabilized by medicaments, etc. to meet the requirements of environmental protection, and then transported to landfills for landfill. [0003] The currently running fly ash solidification process sequence is: the material is weighed with a gravity weighing scale or a spiral weighing scale. When the material reaches the set parameters, it is directly put into the mixing and stirring equipment. Afte...

AI Technical Summary

Problems solved by technology

When the fly ash is mixed with water or chemicals, a large amount of dusty water vapor will be generated, and the weighing scale is installed directly above the mixing equipment. When the discharge door of the weighing scale is opened, a large amount of dusty water vapor in the mixing equipment will enter the scale. In the body, the discharge door of the scale body and the internal material are hardened, which leads to a decrease in weighing accuracy, and finally the program cannot run automatically because the material is not unloaded.
