CASSETTE FILTER, FILTRATION DEVICE AND GAS TURBINE WITH SUCH CASSETTE FILTER Russian patent published in 2013 - IPC B01D46/52 F02C7/00 

FIELD: process engineering.

SUBSTANCE: set of invention relates to device intended for withdrawal of particles from airflow and used in gas turbines, steam generators, gas compressors, etc. Proposed filter comprises upstream and downstream ends, mount frame to support sealed filtration medium and cassette filter to be fitted in baffle openings. Said mount surface is arranged between said upstream and downstream ends of cassette filter at first distance D_up and second distance D_down from said upstream and downstream ends, respectively. Magnitude of said distances exceeds 10% of total length L of cassette filter. Filtration device comprises baffle with opening and mount surface around said opening. Cassette filter is fitted onto baffle mount surface so that filter filtration medium extends beyond both sides of said mount surface. Gas turbine includes at least one said cassette filter.

EFFECT: higher efficiency of filtration, longer life.
