Gas Turbine Air Intake Filters is mainly composed of bracket, ash hopper, filter chamber, clean air chamber, filter bag, blowing device and controller. Make up the series. Each unit has 24 rows of 12 filter bags. Each unit has 336 filter bags with a filter area of 800㎡. The filter bags are 6 meters in length and 130 mm in diameter. The filter bag is made of polyester needle felt.
◆Working Principle
The dust-laden gas enters the ash hopper through the air inlet, and the dust-laden gas enters the clean air chamber through the filter bag as clean air, and then is exhausted by the fan through the exhaust port of the clean air chamber. Dust accumulates on the outer surface of the filter bag and keeps increasing, which makes the resistance of the dust collector rise continuously. In order to keep the resistance of the equipment not exceeding 1200PA and the dust collector to continue to work, regular dust removal is required. Dust cleaning is performed by the program controller to start the pulse valve sequentially, so that the compressed air (0.5-0.7MPa) in the bag is ejected from the hole of the blowing pipe (primary air), and the ambient air (secondary air) that is several times larger than the primary air is induced. Entering the filter bag makes the filter bag expand rapidly in an instant, and with the reverse action of the air flow, the dust is shaken off to achieve the purpose of dust removal. Gas Turbine Air Intake Filters.
◆Equipment Advantages
1. Structure. Gas Turbine Air Intake Filters.
The injection pressure is low, usually 0.25-0.35Mpa, and the energy consumption of dust cleaning is greatly reduced, which further increases the service life of the bag.
2. Save. Gas Turbine Air Intake Filters.
The volume is small, the pressure difference display function is complete, the adjustment is convenient, and the gas consumption is saved.
3. Performance. Gas Turbine Air Intake Filters.
Good sealing, compact structure, light weight, small footprint.
4. Convenience. Gas Turbine Air Intake Filters.
Good sealing performance, easy disassembly and assembly, the bag cage is supported on the flower plate, no pressing device is needed.
