GA series atmospheric dust cleaning bag filter

The dust cleaning system of the GA series atmospheric dust bag dust collector uses high-frequency vibration and back blowing. The back blowing is realized by a designed motor driving a three-way valve. The action of the electric cylinder is controlled by an automatic control system, which is different from the previous method. Compared with the pulse backflush and high-pressure backflush bag dust collector, in addition to saving investment in supporting auxiliary equipment, it also significantly reduces power consumption and equipment operating costs. It also has stable performance, dust removal, convenient maintenance, The filter bag has the advantages of long service life. GA type atmospheric ash cleaning bag dust collector is widely used in building materials, ceramics, metallurgy, food, chemical industry, casting, light industry and other industries.

Working principle of GA series atmospheric dust bag dust collector:

The dusty gas enters the ash hopper from the air inlet pipe, and then is purified upward through the filter bag in the box. It is discharged from the main valve plate opened by the electric three-way valve to the air outlet pipe. The gas in the air outlet pipe is then discharged into the atmosphere through the centrifugal fan and the chimney. middle.

As the working time increases, the thickness of the dust layer on the inner wall of the filter bag gradually increases, and the resistance also gradually increases. When the resistance rise reaches 80 to 120 mm of water column (can be seen through the U-shaped pressure gauge), the electric When the cylinder is started, the main valve plate of the electric three-way valve is closed and the auxiliary valve plate is opened for backflushing and cleaning.

After the backflush air enters the box through the electric three-way valve, it passes through the filter bag in the opposite direction compared to the filtering state. At the same time, the high-frequency vibrator starts to act, causing the filter bag to vibrate at high frequencies. It has a dust cleaning effect under the simultaneous action of backflush and high-frequency vibration (the cleaning time is adjustable). When cleaning is completed, the high-frequency electric vibration stops. The main valve plate of the electric three-way valve is opened and the auxiliary valve is closed at the same time, returning to the normal filtration state. The adjacent intervals of dust cleaning can be adjusted as needed so that each box can be cleaned in sequence at the specified time.
