GA type atmospheric cleaning bag filter

The GA atmospheric dust bag dust collector adopts high-frequency vibration and a reverse blower, which is driven by a designed electric cylinder and a three-way valve. The action of the electric cylinder is controlled by an automatic control system. Compared with previous pulse back blowing and high-pressure back blowing bag dust collectors, it saves investment in supporting auxiliary equipment, significantly reduces electricity consumption and equipment operating costs. With the extension of working hours, the thickness of the dust layer on the inner wall of the filter bag gradually increases, and the resistance gradually increases, reaching 80~When the horizontal column is 120mm (visible on the U-shaped pressure gauge), the electric cylinder begins to close the main valve plate of the electric three-way valve, open the payment valve plate, and blow back to clean the dust. It also has stable performance, easy maintenance, and long lifespan of filter bags. Therefore, the GA series atmospheric cleaning bag filter is widely used in industries such as building materials, ceramics, metallurgy, grain, chemical industry, casting, and light industry. The dusty gas enters the ash hopper through the intake pipe and is then purified upwards through the filter bag inside the box. The main valve plate opened by the electric three-way valve is discharged into the air pipe, and the gas from the outlet pipe is discharged into the atmosphere through the centrifugal fan and chimney.

High pressure (0.5) GA type atmospheric cleaning bag filter; The dust spraying technology for filter bags (~0.7Mpa) can collect more than 90% of dust from gas with a content of ≥ 70% starting from a large amount of powder (particles) ≤ 5 μ m, with an emission concentration of less than 60mg/Nm3. It is widely used in dust treatment in the cement industry. Dust collectors also have great application prospects in industries such as chemical, metallurgical, steel, and power. The dust collector body adopts a fully steel structure design, and the external customers use LBY lightweight rock wool board double-layer insulation. The cold pressing process not only increases the strength of the flower board, but also improves the quality of the equipment. Choose different filter media and their filtration speed according to the working environment.

The working principle of GA type atmospheric dust bag filter:

The dusty gas enters the ash hopper through the intake pipe and is then purified upwards through the filter bag inside the box. The main valve plate opened by the electric three-way valve is discharged into the exhaust pipe, and the gas in the exhaust pipe is discharged into the atmosphere through a centrifugal fan.

With the extension of working hours, 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 increases to 80 and the water column reaches 120mm (as can be seen through the U-shaped pressure gauge), the electric cylinder begins to close the main valve plate of the electric three-way valve, open the payment valve plate, and blow back to clear the dust.

Compared to the filtered state, the blowback air enters the box through the electric three-way valve and passes through the filter bag in the opposite direction. At the same time, the high-frequency electric vibrator began to move, causing the filter bag to vibrate at high frequencies. Simultaneously playing a role in dust cleaning through blowback and high-frequency vibration (with adjustable cleaning time). When the dust cleaning is completed, the high-frequency electric vibration stops vibrating. The main valve plate of the electric three-way valve opens, and the payment valve closes at the same time, restoring the normal filtering state. The adjacent interval time for cleaning can be adjusted as needed, and each box can be cleaned in the specified time sequence.

The GA atmospheric dust removal bag dust removal system adopts high-frequency vibration and a reverse blower, driven by a designed motor to operate a three-way valve, and controlled by an automatic control system.

The GA type atmospheric cleaning bag filter is widely used in industries such as building materials, ceramics, metallurgy, grain, chemical, casting, and light industry.
