APPARATUS FOR REGULATING TWO-PHASE FLOW AND PORTABLE ATOMIZER BASED ON TWO-PHASE FLOW

摘要

The apparatus comprises a mixing chamber (2) formed in a chassis (8) outfitted with separate inlet channels for conveying pressurized liquid phase and gaseous phase and an outlet channel (19) linking the mixing chamber with a spray nozzle via a flow tube (20). Moreover, a separate cylindrical packing chamber (1) is formed in the chassis (8), within which packing chamber a rotor (3) with vanes (5) is set, the vanes of which rotor intermittently close the inlet channels of the two phases formed in separate sectors of said packing chamber (1) as demarcated by the rotor vanes (5), wherein the gaseous phase inlet channel (11) is closed alternately with at least one liquid phase inlet channel (12) conveying liquid phase into the mixing chamber (2) via open inter- vane channels, wherein also the sector of the packing chamber (1) containing the gaseous phase inlet channel (11) is separated from the mixing chamber (2) by a continuous section of a partition (7) that closes off the rotor's (3) inter-vane channels within this sector. The portable atomizer of liquids is equipped with a liquid phase vessel (22), a source of pressurised gaseous phase, and an apparatus for regulating two-phase flow. The apparatus has a mixing chamber (2) formed in a chassis (8) having separate inlet channels for conveying pressurized liquid phase and gaseous phase and an outlet channel (19) linking the mixing chamber (2) with a spray nozzle via a flow tube (20), wherein the gaseous phase inlet channel (11) is connected with the source of gaseous phase via a gas tube (9), while in the chassis (8) a separate cylindrical packing chamber (1) is formed, within which a rotor (3) with vanes (5) is set. The vanes (5) intermittently close the inlet channels of the two phases formed in separate sectors of said packing chamber (1) as demarcated by the rotor vanes (5), wherein the gaseous phase inlet channel (11) is closed alternately with at least one liquid phase inlet channel (12) conveying liquid phase into the mixing chamber (2) via open inter- vane channels, wherein also the sector of the packing chamber (1) containing the gaseous phase inlet channel (11) is separated from the mixing chamber (2) by a continuous section of a partition (7) that closes off the rotor's (3) inter-vane channels within this sector. Furthermore, the chassis (8) is situated inside the liquid phase vessel (22) and the gas tube (9) situated in the liquid phase vessel has a number of small orifices (10) in its wall.
