The role of pulse valve in bag filters and the working principle

The bag filter has the characteristics of high purification efficiency, large air volume, stable performance, long service life and wide application range. The equipment is widely used in metallurgy, foundry, chemical industry, building materials, food, machinery, light industry, rubber and other industrial and mining enterprises, dust removal, to improve the environment to prevent air pollution, has played a good effect.
Working principle Dust-laden gas enters the bag filter through the inlet of the bag filter. After the large space of uniform wind, the filter bag is evenly worn. The material is trapped by the filter bag and deposited on the outer wall of the filter bag. The filtered clean gas The venturi tube is discharged from the exhaust pipe after entering the upper case. An electromagnetic pulse valve is installed on the bag filter, and the pulse valve is opened at regular intervals so that the compressed air is injected from the holes of the blowing pipe to the corresponding Venturi tubes, and the excess dust on the filter bag is cleared, so that the bag maintains smooth ventilation and continuous operation. The clear material is sent from the auger under the bag. Application range: In addition to the features of high purification efficiency, large air volume, stable performance and long service life, dmc type pulse bag dust collector has the characteristics of high technical performance and wide application range. The equipment is widely used in the ventilation and dust removal of industrial boilers, industrial boilers, steel mills, metallurgy, foundry, chemicals, building materials, food, machinery, light industry, rubber and other industrial and mining enterprises, to improve the environment, pulse valve, refers to the electromagnetic or pneumatic, etc. The control of the pilot valve can instantly open and close the high-pressure gas source to generate a pulsed diaphragm valve. Electromagnetic pulse valve, a diaphragm valve that combines a solenoid valve, a pilot valve, and a pulse valve and is directly controlled by an electric signal.
According to the valve inlet and outlet angle and the form of the inlet can be divided into three types:
a) Right-angle electromagnetic pulse valve: Diaphragm valve whose inlet and outlet of the valve body is at a right angle and directly controlled by electric signals;
b) Straight-through electromagnetic pulse valve: diaphragm valve with inlet and outlet of 180 degrees directly controlled by electric signal;
c) Submerged electromagnetic pulse valve: Diaphragm valve whose air inlet of the valve body is submerged in the air bag and directly controlled by the electric signal.
