  B.Dust collector working principle

The dust-containing gas enters the main pipeline from each dust removal branch pipeline and then enters the cyclone dust collector. After filtering out a part of the coarse dust particles, it enters the bag filter entrance and enters the ash hopper from the dust collector air inlet. Due to the gravity of the dust, the coarse particles settle directly in the ash hopper under the action of gravity. The remaining dust-containing gas rises to the middle box through the guide plate and is evenly distributed in each filter bag. At this time, the dust is retained on the outer surface of the filter bag, and the filtered clean gas enters the upper box through the bag flower plate and is discharged from the exhaust duct. When the dust on the surface of the filter bag thickens to a certain extent (set time). The pulse control device sends a signal to close the air inlet valve of the first chamber, and the blowing device starts to work. Compressed air is sprayed to the filter bag through the pulse valve and the nozzle on the blowing pipe in a very short time, making the filter bag vibrate. Under the action of vibration force, the dust attached to the outer surface of the filter bag is separated from the filter bag and falls into the ash hopper. When the first chamber of the dust collector is cleaned, the air inlet valve of the first chamber is opened and the air inlet valve of the second chamber is closed. The first chamber participates in the filtering work again, and the second chamber starts to clean offline. From then on, it is carried out chamber by chamber. Since offline cleaning is realized, the cleaning effect is improved. The entire cleaning control is controlled by PLC programmable controller, and the control mode can be divided into two forms: automatic timing and manual control.
