Preferably, above-mentioned a kind of Novel bag-type dust remover, wherein said filter bag is 950g/m2Fluorine this filter bag beautiful.
Preferably, above-mentioned a kind of Novel bag-type dust remover, is provided with bag filter tubesheet inside wherein said cleaner body, Offering card hole on described bag filter tubesheet, described filter bag hangs with described card hole and is connected.
Compared with prior art, the utility model has the technical effect that following two aspect:
(1) the utility model allows to use when the cigarette temperature of spray drying tower outlet occurs more than selected cloth bag filtrate During temperature, open bypass make flue gas through bypass flue discharge and without filter bag, thus be effectively protected filter bag be not burned out or High-temperature oxydation, protects filter bag, extends life of bag filter;Washing tower at spray drying tower, when stopping tower, opening bypass makes flue gas through side Road air flue emission and without filter bag, thus effectively prevent the dust stratification condensation on cloth bag from causing " paste bag " phenomenon.
(2) in the utility model, deduster air intake uses lower air inlet mode, utilizes the flue gas of different wind inlet section at air inlet Part major diameter granule dust is separated by flow velocity height, serves one and reduces larger particles flow velocity, pre-except bulky grain powder The effect of dirt, gas enters deduster from the bottom to top simultaneously, make the flue gas of entrance have a smoke distribution and cigarette speed equilibrium when Between, space, air inlet has enough distances between at the bottom of cloth bag, thus avoids dusty gas and directly washes away filter bag, enters one Step improves the efficiency of whole dust arrester, the service life of filter bag, the effective service life extending rear portion filter bag.Meanwhile, During deashing, blows air enters filter bag through being vented contrary direction from top to bottom from filter bag outlet, makes filter bag radial deformation shake off Dust is in ash bucket, and deashing is that pulse valve takes turns to operate one by one, and deashing ability is strong, and efficiency of dust collection is high, stable and reliable operation, economical Profitable.
