The invention relates to a sticky
smoke dust removal
system and method for actively regenerating pre-sprayed
powder for a
coke oven. The tops of bag type dust removers are provided with purified gas outlets; the purified gas outlets are connected with a dust removal fan, a
muffler and a
chimney in sequence; the lower parts of dust removal chambers of the bag type dust removers are provided with
smoke dust inlets; the
smoke dust inlets are connected with dust remover inlet pipelines; the dust remover inlet pipelines in front of the smoke dust inlets are provided with pre-sprayed
powder inlets;the pre-sprayed
powder inlets are connected with a powder exhaust
nozzle of a powder active regeneration and jetting integrated device through powder conveying pipelines; the bottoms of ash bins of the bag type dust removers are provided with ash outlets; the ash outlets are connected with a mill dust inlet and a mill dust bin of the powder active regeneration and jetting integrated device respectively through a scraper. The sticky smoke dust removal
system is used, through configuring the powder active regeneration and jetting integrated device, for realizing the automatic addition, the excess material outward delivery, the active
pyrolysis and regeneration, the automatic
spray coating, the output amount regulation and the recycling of the pre-sprayed powder in the dust removal
system; the pre-sprayed powder does not need to be externally supplemented, and thus, the reliable and stable running of the dust removal system is ensured.
