FIELD: separation of products of oil wells into phases; oil and gas producing industry; degassing of liquids. SUBSTANCE: proposed multi-hydro-cyclone includes housing, hydro-cyclone members, drain chambers and pipe unions for supply of product and discharge of separated phases. It is provided with gas collecting chambers with screen and gas tube having toroidal surface at the end; it is so mounted on hydro-cyclone members that center of outer toroidal surface reaches edge of drain chamber. EFFECT: enhanced operational efficiency due to reduction of entrainment of dropping liquid and retaining of vapor-and-gas hole. 3 dwg
