To provide a snow-attach preventing apparatus for a suction filter of gas turbine capable of preventing filter from being clogged with snow by removing the snow inflowing from the suction port at the front face, so as not to make attachment to the filter.
A house 10 for a gas turbine is furnished with a suction port 17 to suck the air 30, and water drops and snow are removed from a room 24 by a demister 1, and the air removed of dust by a filter 16 flows to a duct inlet 23 from a room 25 and is led to the gas turbine. A water-sprinkling nozzle for sprinkling water in summer, etc., is installed at the inlet of the suction port 17, while another 7 for sprinkle water to the snow inflowing in winter is installed at the entrance to the room 24. The demister 1 is installed on the front face of the filter 16, to remove also permeating water drops, rainwater, and snow. The demister 1 is formed with an eliminator, a water louver, or a wire pad, and the inflowing snow is allowed to contain water using the nozzle 7, while the snow attached to the demister 1 is dropped off by the weight of the water contained, and will not attach to the filter 16. The differential pressure between inside and outside the filter 16 will not rise either.
