AIR-CLEANING DEVICE OF GAS-TURBINE DRIVE Russian patent published in 2011 - IPC F02C7/55 F02C7/47 

FIELD: machine building.

SUBSTANCE: air-cleaning device of gas-turbine drive consists of air receiving chamber with filter elements arranged in it and sediment retaining surfaces before inlet orifices formed on it, and of gas ducts of system of cycle air heating. Sediment retaining surfaces are made on the air receiving chamber before inlet orifices. Sediment retaining surfaces are made in form of sheets perforated with cells of laminar type. Sediment retaining sheets are preferably made of plastic materials. Dimensions of the device are decreased due to design of sediment retaining surfaces made of sheets perforated with orifices of laminar type. Additionally, air penetrability of sediment retaining sheets reduces windage of the structure and reduced dimensions decrease snow load and metal input of the structure.

EFFECT: increased operational reliability.
