Pulse Jet Bag Filter

Our SG Enviro Technologies Manufacturing a pulse jet bag filter, which is also Noted a pulse jet bag house, is a type of highly efficient reverse jet dust collector equipment developed from the design of Our traditional bag filters. It is especially good at collecting tiny dry non-fibrous particulates, which makes it an indispensable device for controlling air pollution in many industries. Filter Bag house dust collectors are regarded as highly effective systems that are capable of achieving up to 99% efficiency. Depending on the design and fabric filter, bag house filters remove and can withstand or capture abrasive particles, Food Processing Dusts, Shot Blasting Unit Dusts, Wood Curving Dusts, mists, fumes and fine powders.

Working Principle Of Pulse Jet Bag Filter

Filtration principle

When the dusty gas enters from the air inlet and passes through the dust hopper, due to the rapid expansion of the volume, some large dust particles are separated by inertial force and directly fall into the dust hopper. The remaining dust particles are sent into the bag room with the airflow. In the bag room, after passing through the filter bag, the remaining dust is blocked in the bag’s outer surface. The purified Air enters the upper case and is discharged through the air outlet.

Dust cleaning principle

With the increase of equipment working times, the dust on the filter bag is continuously accumulated, and the equipment resistance rises. When the equipment resistance rises to the set value, the pulse jet controller issues a command and the pulse jet device starts to work. The poppet valve is first to be closed so that the bag room is in a state of no airflow. Then the pulse valve opens and the high-pressure reverse air expands in the upper case in a very short time. They flow into the filter bag causing deformation and vibrating so that the dust attached to the outer surface of the filter bag is stripped and dropped into the dust hopper. After the dust cleaning process is finished, the pulse valve is closed and the equipment returns to a normal filtering state. As the equipment is composed of many chambers, the dust cleaning process will be carried out in each chamber in turn. When one chamber is clearing ash, the other chambers are still working normally, thus ensuring the normal operation of the equipment.

Dust collecting The dust intercepted by filtration and cleaning will fall into the dust hopper and then discharged through the gate valve and the pneumatic dust discharge valve. Finally, they will be transported by the conveyor.
