FIELD: power engineering. ^ SUBSTANCE: invention relates to devices for preparation of atmospheric air for use in gas-turbine plant, and it can be used in different climatic zones. Proposed complex air preparation device of gas-turbine plant contains the following devices installed in tandem in direction of air flow: air intake unit, anti-icer, inertia cleaning unit with dust suction fans, fine filter unit, bypass unit and noise damping unit. Air intake unit is furnished with protective lip at inlet. Bypass unit is provided with operation control pickups connected to control system of gas-turbine plant. Noise damping unit is connected through adapter with inlet branch pipe of turbocompressor. Inner surface of protective lip of air intake unit is covered with noise-absorbing material. Anti-icer is arranged in air intake unit and is made in form of air-distributing duct divided by partition into two sections. Inner surface of section, first in direction of hot air flow, is covered with noise-absorbing material. ^ EFFECT: improved efficiency of noise damping in all components of air preparation device of gas-turbine engine. ^ 2 cl, 3 dwg |
