FIELD: oil refining; gas; petrochemical industries.
SUBSTANCE: invention relates to separation devices for separating gas-liquid flows in a centrifugal field and can be used, for example, in technological processes of gas separation in the oil refining, petrochemical and gas industries. A centrifugal-vortex two-flow separator is proposed, which contains a housing 1, the inlet of the gas-liquid flow into the separator comes from a common pipeline with branching into two nozzles, each of which has a fine adjustment valve 3, 5, and the nozzles are placed vertically in the separator housing with a lower 2 and upper 4 tangential inlet into the separator. By means of the lower tangential branch pipe 2, an entry into the separation chamber 8 is carried out through an annular channel 9 and swirlers 10 with slotted tangential slots 11. The separation chamber is closed from below with a bottom 12, and from above with a disk 13, in the center of which there is a working nozzle 14 with a conical outlet orifice 15. After the separation chamber, the swirled gas-liquid flow enters the working nozzle 14, from which it exits through the conical orifice 15, after which it enters the conical guide 16, and then the internal cyclone device of the cyclone nozzle 19. At the same time, a part of the gas-liquid flow enters the external cyclone space, limited by the cyclone nozzle 19, the lower 17 and the upper 18 cones, by means of the upper tangential nozzle 4 and the valve 5. As a result, the flow swirled in the cyclone device due to centrifugal forces is divided into two rotating streams, divided into axial and peripheral. At the same time, a separated liquid is released from the peripheral flow, which flows down into the annular slot 20 along the wall of the cylindrical insert, accumulates on the surface of the disk 13, and then flows through the holes (14a) into the annular space 7, followed by entry into the cubic collector 34.
EFFECT: increase in productivity while maintaining high efficiency of the separation process.
