Pulse bag dust collector is also called pulse dust collector, air pressure baghouse and pulse baghouse. Since the pulsed baghouse dust collector came into being, it has made great progress in the purification of dust-containing gas after extensive use and continuous improvement. Due to advanced ash cleaning technology and greatly improved gas-cloth ratio, it has the characteristics of large air volume, small footprint, high purification efficiency, reliable work, simple structure and small quantities of maintenance. Dust removal efficiency can reach more than 99%. It is a kind of mature, perfect and efficient dust removal equipment.
Under the gravity of the fan, dust gas comes into pulse dust collector through pipes. Then air flow upwards under the action of wind deflector. As flow pressure drops, large particles of dust in part is separated out due to inertia effect, falling into the ash bucket. After that, dust is trapped on the outer surface of the filter bag, and the purified gas enters the upper body box through the filter bag mouth and is discharged by the air outlet.
With the continuous increase of dust on the surface of the filter bag, the pressure difference between the inlet and outlet of the dust collector also rises. When the resistance of the dust collector reaches the set value, the control system issues the ash cleaning instruction and the ash cleaning system starts to work.
First, the solenoid valve is opened immediately after receiving the signal, so that the compressed air in the upper air chamber of the small diaphragm is discharged. Due to the change of the force on both ends of the small diaphragm, the exhaust channel closed by the small diaphragm is opened. Thus, the compressed air in the chamber is discharged from this channel so that the force on both ends of the large diaphragm is changed. Then the large diaphragm acts, and the closed output port is opened. After that, the compressed air in the air bag is sprayed into the bag through the output pipe and the blowing pipe to clean the dust. When the control signal stops, the solenoid valve is closed, the small diaphragm and the large diaphragm are reset one after another, and the blowing stops. The shaken dust falls into the ash hopper and is discharged out of the machine through the ash discharge valve.
