FIELD: technological processes.
SUBSTANCE: invention may be used in mining industry. Separator intended for separation of coal bed gases is placed in cavity of mine. Hydrocarbons separated in separator are exhausted via gas line, and volume of gases discharged from mine is substituted with atmospheric air. Separator comprises body with nozzle of gas inlet 14, nozzle of light gas discharge 12 and nozzle of heavy has discharge 1, engine 20. In toroidal cavity 5 of separator body there is radial-axial centrifugal compressor installed with hollow blades, in which frontal slots 1 and rear slots 2 are provided. Propeller 10 is fixed on tubular extension of shaft 11. To inner surface of propeller 10 there are blades of radial-axial centripetal compressor 9 fixed.
EFFECT: efficient separation of heavy and light gases, reduction of power inputs for air conditioning in mine.
