AIR CLEANER OF GAS-TURBINE DRIVE Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed gas cleaning device is designed for cleaning atmospheric air being prepared for delivery into compressors of gas-turbine drive to protect blading from abrasive wear by increasing degree of air cleaning and reducing operating noises of drive. In proposed air cleaning device of gas-turbine drive containing air intake chamber with gangs of cyclone separators installed at its outer walls and plate-and-slot-type noise silencer made in form of blocks of plate installed from inner sides of air intake chamber whose planes are square to walls with fitted-on gangs of cyclone separators, blocks of said plates are installed at equal distance from inner walls of air intake chamber thus forming collectors in between. Air passing partitions are installed behind blocks of noise silencers to form thechnological spaces. Fine air cleaning cassettes are installed on air passing partitions from side of outlet channel of air intake chamber. EFFECT: reduced pressure losses for friction in air cleaning duct, increased efficiency of gas- turbine plant and gas transfer set as a whole, improved operating characteristics. 2 cl, 1 dwg
