A flue gas fly ash stabilizing system is a common device used in the flue gas treatment of an incineration plant. In the flue gas fly ash stabilizing system, chelating agent or inorganic agent is used to react with heavy metal in the flue gas fly ash to obtain the fly ash solid-phone stabilization product. In the process of treating fly ash, as in patent application No. CN201820132060.2, the flue gas treatment structure includes a fly ash weighing scale and a mixer, and the system needs to weigh the fly ash participating in the reaction each time by the fly ash weighing scale and mix and stir the flue gas fly ash and the reactant by the mixer. The fly ash of the flue gas is easy to raise dust and is hazardous waste, so the fly ash is not allowed to overflow in the ventilation process of the equipment; at the same time, in order to prevent the unsmooth feeding of the fly ash caused by the closed environment during operation, ventilating devices are generally arranged on the fly ash weighing scale and the mixing stirrer.
In the conventional common ventilation device, a fly ash weighing scale and a mixing stirrer are often provided with a ventilation cover, as shown in fig. 1, the ventilation cover mainly comprises a filter cover and a filter cover support frame, the filter cover is usually made of industrial canvas, and the filter cover is often hardened on the inner wall of the filter cover due to moisture absorption of fly ash in the actual use process to cause the ventilation effect to be greatly reduced, so that the working efficiency of the system is reduced. Also, as shown in fig. 2, the main principle of this method is that a dust-removing fan is used to extract the dust-containing air in the fly ash weighing scale 1 and the mixer 2 by a dust-removing fan a1 and then discharge the air into a water film processor a2, and the fly ash in the dust-containing air is filtered by water a3 in the water film processor and then discharged into the atmosphere through an air outlet a 4; because of the hazardous waste characteristic of the flue gas fly ash, the device changes the slurry fly ash generated by fly ash precipitation and the water in the water treatment device into hazardous waste, and needs to carry out harmless treatment on the slurry fly ash and the water in the water film treatment device, thus leading to very high system operation cost.

Detailed Description
As shown in fig. 3, the utility model relates to a flue gas flying dust processing structure for flue gas flying dust stabilization system, it includes: the device comprises a fly ash weighing scale 1, a mixing stirrer 2, fly ash conveying equipment 3, a pulse back-blowing dust remover 4 and a temporary storage bin 6.
The discharge port of the fly ash weighing scale 1 is communicated with the feed port of the mixing stirrer 2, and the fly ash transportation equipment 3 is communicated with the feed port of the fly ash weighing scale 1. The dust-extraction-based pipeline 5 of the pulse back-blowing dust remover 4 is respectively communicated with the fly ash weighing scale 1 and the exhaust port 2 of the mixing stirrer; the discharge outlet of the pulse back-blowing dust remover 4 is communicated with the fly ash conveying equipment 3; the dust discharging port of the pulse back-blowing dust remover 4 is communicated with the temporary storage bin 6; the temporary storage bin 6 is communicated with the fly ash transportation equipment 3.
The pulse back-blowing dust collector 4 includes: dust extraction fan (not marked in the figure), pulse blowback device (not marked in the figure), filtration (not marked in the figure), the utility model provides a pulse blowback dust remover 4 realizes based on the pulse blowback dust remover among the prior art, if: a bag-type pulse back-blowing dust collector, a cyclone bag-type pulse back-blowing dust collector, a filter cartridge type pulse back-blowing dust collector and a bin top type pulse back-blowing dust collector.
