Bag?type dust collector?is a kind of?dry?dust filtering?device.?Filter used for a period of time,?due to the sifting,?collision,?retention,?diffusion,?electrostatic and other effects,?the bag?surface?of a layer of dust,?this layer of dust?known as the first layer,?in which the future course of the?movement,?became the first layer?mainly?filter layer?filter material,?rely on?the role of the early levels,?larger mesh?the filter?can get a higher filtration efficiency.?As the?dust?on the filter surface?accumulation,?efficiency and resistance?of the dust collector?are increased correspondingly,?when?the filter pressure difference on both sides?is large,?will put?some?has attached?to small dust?particles in the filter on the?squeeze in the past,?so that the?precipitator efficiency?decline.?In addition,?the resistance of the dust collector is?too high will make the?dust removal system?of the?wind dropped significantly.Therefore,?the dust collector resistance?reaches a certain value,?to timely cleaning.?Cleaning can not be destroyed when?the first layer,?to avoid reduced efficiency.
Two、 the scope of application
Solid separation?we?dye,?pharmaceutical,?plastic?and?printing factory,?paint factory,?food processing,flour,?electronic?industry,?wood?processing and other fields?of liquid?and fine?material recoverytreatment and purification?collection.
Three、the principle of work
When the?dust contained gas from the?inlet?into the dust,?met at the?air inlet and outlet?of theinclined plate?and the?middle?baffle,?flow?turned?into ash hopper,?while the air flow?speed?slow down,under the inertia effect,?gas?dust?settling into the?hopper?of coarse particles?directly,?since?the role of?airflow?with?dust?in advance,?after?folding?to?filter bag?dust?through?with internal?metal skeletontrapped in?the outer surface of the filter bag,?purified gas?into the filter bag?chamber?bottom?clean room,?pool to the?discharge outlet.?The process?of dust containing gas?through the filter bagcleaning,?along with the increase of time?more and?more?dust?deposition?in the filter bag,?bagresistance increases,?causing the?air handling?gradually reduced,?must carry on the?cleaning of the bag,?so that the?product?of?shedding?in?the filter bag dust?filter bag?surface,?regeneration.?Clear?the dust falls into the?bucket,?the?ash discharge system and?discharged out of the machine body.Thereby the?deposition?in the filter bag?dust?cycle of?the?pulse jet?cleaned,?the purification of?gaspassed normally,?ensure?the normal work of?the dust removal?system.
Body structure of?bag type dust collector?is mainly composed of?an upper box body,?a box body,?the middle?lower case?(Hui Dou),?the ash cleaning?system and?ash body?parts.?Device?performance?of bag type dust collector?is good or bad,?in addition to?the correct choice of bag material,?ash cleaning system?plays a decisive role in?the bag type dust remover.?Therefore,?the ash cleaningmethod is one of the?characteristics that distinguish?bag type dust collector,?an important link?in the operation?is also a?bag type dust collector.
