The third dedusting of steelmaking, namely the dedusting of the steelmaking workshop roof, is a dedusting facility built to achieve ultra-low emission and solve the problem of smoke dust overflowing from the top of the steelmaking workshop. The pollution sources treated by the third dedusting of steelmaking mainly include the smoke dust that escapes to the roof during the smelting process of the steelmaking furnace (electric furnace, oxygen blowing converter, etc.), which can not be collected by the primary and secondary dedusting; the dust raising caused by the production process nodes that were not included in the dedusting pipeline network due to the environmental protection control requirements and other objective conditions at that time; the dust raising formed by the unorganized emission, which is lifted by the hot air of the steelmaking workshop and scattered out of the workshop through the top air window, resulting in atmospheric pollution.

What are the environmental protection equipment for waste gas treatment? The equipment for treating organic waste gas produced in industrial production includes spray tower, activated carbon ads box, UV photolysis purifier, UV photolysis activated carbon integrated machine, plasma activated carbon integrated machine, kitchen fume purifier, catalytic combustion.

The dust-laden gas is introduced into the middle shell from the inlet by the induced draft fan, and the clean gas enters the upper shell the filter bag and the venturi tube, and is discharged from the clean gas outlet, while the dust is retained on the outer wall of the filter bag.

(1) Mining. All quarries must be blasted by approved professional blasting companies. The drilling process for uses hydraulic down-the-hole drilling rigs (drilling rigs with dust collection devices), which effectively solves the problem of dust pollution caused by manual pneumatic drilling; the blasting adopts the deep hole micro-differential blasting method, and the mine blasting adopts the loosening blasting method. Spraying and watering measures are taken for the blast pile and mining and loading operation to achieve the purpose of mine management.

Three times dust removal for steelmaking, three times dust removal for steelmaking
