COMPLEX AIR CLEANING DEVICE Russian patent published in 2011 - IPC F02C7/52 

FIELD: engines and pumps.

SUBSTANCE: complex air cleaning device of shaft type for cleaning of cyclic air of gas-turbine plant includes in-series installed weather-protected shield (1), fine cleaning module (5) containing air filters and noise silencing unit connected to gas-turbine engine and located outside the shaft (3), and they are all installed in air flow suction direction. The above device differs by the fact that it is equipped with air cleaning stage located before fine cleaning unit through multi-cyclone units (4), air filters are located in the shaft throughout its height, noise silencing unit consists of modules (8, 9, 10) of plate-and-slot type, which are installed at least in two tiers; at that, the last module of upper tier (10) in the suction direction of air flow has the shape of triangle in vertical cross section.

EFFECT: improving efficiency of gas-turbine plant by decreasing hydraulic and aerodynamic losses in complex air cleaning device, and improving operating reliability at simultaneous simplification of the design of complex air cleaning device.
