DIRECT-FLOW CENTRIFUGAL SEPARATOR Russian patent published in 1999 - IPC

FIELD: purification of natural gas transmitted through trunk pipes before processing by gas distribution stations. SUBSTANCE: device is designed as outer cylindrical tube which is coaxial to separation chamber which is embedded into cylindrical tube and contains tangential vortex generator. Output of separation chamber has pipe for removal of purified gas. Its diameter is less than diameter of separation chamber and shapes receiving ring slit with respect to its inner wall in order to remove trapped phase. Output path of trapped phase is designed as longitudinal through tangential channels with sharp input edges, which outputs to lower piece of collector are connected to outlet for trapped phase removal which is designed as vertical T-junction. Ring space behind collector is equipped with serial circuit of two inertial separator, first of which is designed as axial vane vortex generator and second of which is designed as through tangential channels which are located in upper part of output terminal of pipe for removal of purified gas. Rest of fine trapped phase is removed by means of pipe which is located in lower half of ring space which is connected to space of vertical outlet for collecting trapped phase. EFFECT: increased load range. 2 cl, 4 dwg
