COMPLEX AIR CLEANING DEVICE OF ACCUMULATING TYPE FOR GAS-TURBINE PLANTS, AND ITS VERSIONS Russian patent published in 2013 - IPC F02C7/52 F02C7/45 

FIELD: machine building.

SUBSTANCE: complex air cleaning device (CACD) of gas-turbine plant (GTP) includes a protective cap made from translucent cold-resistant non-metallic material on load-carrying rib-stringer frame, under which filtering elements of accumulating type are mounted on their own power frame on prismatic supporting structures with equally truncated triangular bases. Developed surface made in the form of truncated pyramid is provided on edges of protective cap along its perimetre. The specified additional surface has two design versions: stationary design - without any possibility of changing the surface area of CACD inlet section, and adjustable design - with possibility of changing the specified surface area in one of the design versions. As per one of the design versions, the change of surface area of CACD inlet section is performed by making the developed surface in the form of shutters controlled by means of hinged lever parallelogram actuating mechanisms. Surface of shutters is made in the form of louvre controlled with other parallelogram actuating mechanisms.

EFFECT: increasing operating efficiency of the device owing to improving the operating conditions of filtering elements; reducing the level of hydraulic losses and metal consumption; improving personnel labour conditions; reducing the power consumption for performance of routine maintenance.
