Jet Pulse Bag Filter

The jet pulse bag filter is an advanced high-efficiency bag dust removal equipment. It is a large-scale dust removal equipment with large air volume, good dust removal effect, high dust removal efficiency, reliable operation, convenient maintenance, and small footprint.

The jet pulse bag filter is when the dust-laden gas enters the dust collector from the air inlet, it first hits the inclined plate and baffle in the middle of the air inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down. The coarse particle dust in the gas flows directly into the ash hopper. It plays a role of pre-collection of dust. The airflow entering the ash hopper is then folded upwards and passes through the filter bag with a metal skeleton inside. The dust is trapped on the outer surface of the filter bag. The purified gas enters the upper clean room of the filter bag chamber and is collected to the outlet. The air outlet is discharged, and the dust-containing gas is purified through the filter bag. As time increases, more and more dust accumulates on the filter bag, which increases the resistance of the filter bag, resulting in a gradual decrease in the processing air volume. For normal work, it must be controlled When the resistance is within a certain range (140-170 mm water column), the filter bag must be cleaned. When cleaning the dust, the pulse controller will trigger each control valve to open the pulse valve in sequence, and the compressed air in the air bag will pass through the venturi through each hole of the nozzle Sprayed into each corresponding filter bag, the filter bag instantly expands rapidly, so that the dust accumulated on the surface of the filter bag falls off, and the filter bag is regenerated. The cleaned dust falls into the ash hopper and is discharged from the body through the ash discharge system. As a result, the dust accumulated on the filter bag is periodically pulsed to clean the dust, so that the purified gas can pass through normally, and the operation of the dust removal system is ensured.

structure type

1. The jet pulse bag filter is a box structure, which is mainly composed of eight parts: truss, ash hopper, middle box, upper box, injection device, ladder and platform, inlet and outlet air ducts, and PLC control system.

2. The pulse cleaning adopts PLC control system, and the time is selected. The pressure difference can also be controlled according to the user's needs. The electromagnetic pulse valve is controlled by PLC, and compressed air is used to clean the dust. The control method is online control.
