Three-flow vortex tube TVT

The three-flow vortex tube contains a housing 1, to which an inlet nozzle 2 is connected, a swirler is installed coaxially in the casing, in the form of an Archimedes spiral 3 and a diaphragm with an inner conical surface 4, a separator 6 is installed coaxially with the casing 1 into the cold gas outlet nozzle 5. its cylindrical surface is attached to a branch pipe for draining the liquid 7. From the opposite end of the housing 1, an energy separator 8 is fixed, followed by a swirler 9. A branch pipe for the outlet of hot gas is coaxially fixed to the swirler 9.

The compressed gas is supplied through the inlet pipe 2 into the swirler, in the form of an Archimedes spiral 3. The gas, under the action of centrifugal forces and the direction of movement in the swirler, in the form of an Archimedes spiral 3, acquires a vortex-like structure, then the gas is directed to the energy separator 8, where due to the friction of the axial countercurrent vortex about near-wall direct-flow vortex, and in conjunction with centrifugal forces, energy separation occurs. As a result of this process, the gas is divided into hot, passing through the swirler 9 and the hot gas outlet 10, and cold, which, in turn, is directed to the diaphragm with an inner conical surface 4 by an axial countercurrent vortex flow.

Passing through a diaphragm with an inner conical surface, the cold gas carries the smallest droplets of liquid. Since the density of the liquid is greater than the density of the gas, and the flow of cold gas is under the action of centrifugal forces, the smallest droplets of liquid settle on the inner surface of the diaphragm with an inner conical surface and flow through the annular channel 11 into the liquid chamber 12, from where the separated liquid flows down through the liquid drain pipe 7 Cold gas without liquid passes through the inner cavity 13 of the separator 6. Next, the cold cleaned gas passes through the cold gas outlet 5 as intended.
