COMPLEX AIR CLEANING DEVICE FOR CLEANING OF GAS TURBINE PLANT CYCLE AIR Russian patent published in 2009 - IPC F02C7/52 

FIELD: motors and pumps.

SUBSTANCE: invention is related to the field of power engineering, in particular, to gas cleaning devices for cleaning of air taken from atmosphere and its preparation for supply to compressor of gas turbine plant. Complex air cleaning device for gas turbine plant cycle air comprises the following components serially installed downstream air flow suction: weather protection visor, two-section air heating device, unit of inertial cleaning, dust exhaust fans, unit of fine purification comprising air filters, bypass unit comprising bypass valves, noise killer unit connected to compressor inlet nozzle via transient air duct. Downstream weather protection visor and air flow suction, vertical shaft is installed, and weather protection visor is equipped with separating partition. Unit of inertial cleaning, air filters of fine purification, bypass unit and noise killer unit are installed beyond vertical shaft limits, parallel to its lower portion, forming horizontal section of complex air cleaning device. Lower part of vertical shaft comprises turn at 90° with radius equal to 0.30-0.35 of complex air cleaning device horizontal section height. Upstream unit of inertial cleaning, buffer section is provided with length of 0.2-0.3 of complex air cleaning device horizontal section height.

EFFECT: higher reliability of equipment operation due to reduction of inlet non-uniformity and hydraulic resistance of the whole air intake section, and also improvement of its maintenance and repair conditions.
