Process Design of Anti - blowing Bag Dust Collector

Although the pulse jet bag filter has the advantages of high filtration speed and strong cleaning ability, there is still a backflush bag filter when dealing with large flue gas and no compressed air supply.
First, the anti-blowing bag filter classification
1. According to the intake method classification
Anti-blowing bag filter by the intake method is divided into the wind into the wind blowing bag filter and the next into the wind blowing bag dust collector.
1) The inlet manifold of the upper air bag filter is in the upper part of the dust collector. Air into the bag after the bag in the bag from the top down flow, consistent with the direction of falling dust.
2) Down the wind bag filter when the wind main pipe in the dust collector ash bucket position, the air into the bag after the bag in the bottom of the flow from the bottom up, and the opposite direction of dust falling.
2. According to soot cleaning methods of classification
According to soot cleaning methods of anti - blowing bag dust collector is divided into the following three categories.
1) Sub-room backflush cleaning. Sub-room anti-blowing dust bag filter is the application of a more type of dust collector, which is characterized by the dust collector is divided into several rooms, when a room blowing back when the other room normal filter operation. Sub-room backflush dust collector is divided into two types of positive pressure and negative pressure, which negative pressure more advantages. Sub-room anti-blowing bag dust collector is usually used within the round bag filter work.
2) Air ring backflush cleaning. This cleaning method is in the outer filter bag on the outside, close to the surface of the filter bag to set a hollow gap with the ring, the ring can move up and down and with the pressure or high pressure fan pipe connected. The high-speed airflow is discharged from the annular nozzle in the ring, and the dust deposited on the inside of the bag is cleared.
3) Rotary pulsation Backflush Cleaner. This is the way in which the reverse airflow in the backflush mode is pulsating. Its structure is more complex, to have the ability to produce pulsating mechanism, cleaning effect is strong. This kind of anti-blowing bag filter does not divide the flat bag outside filter type.
