The device includes a vertical cylindrical housing 1 with an inner pipe 2, an inlet nozzle 3, an outlet nozzle 4, a condensate receptacle 5. In the center of the housing 1, a shaft 6 is vertically mounted with a turbine wheel 7 located on it, longitudinal rotor blades 8, discs 9, the shaft 6 is mounted Heads 10 and 11 A fixed inner cylinder 12 encloses the turbine wheel 7 and has vertical slots 13 in front of it.

The vertical cylinder of the chamber 14 encloses the cylinder 12, perforated appropriately along the length of the longitudinal rotor blades 8 of the rotor holes 15. The perforation of the cylinder 12 is made of holes 15 with sizes increasing from top to bottom from about 5 to 15 mm.

In the lower part of the chamber 14 there is an intermediate condensate collector 16. And under a rotating rotor, a condensate collector 17, drain pipes 18 and 19 with hydraulic locks 20 and drain pipe 21.

A partition 22 is located in the lower part of housing I, and a partition 23 is located in the end condensate collector 17. It is fixed on shaft 6. Mesh packages 24 are sector-shaped reinforced along the entire length of the longitudinal blades 8 of the rotor. Packages are made of wire or other yarns with a diameter of approximately 0.5-1 mm with mesh openings of 3-5 mm and an external fixing frame 25 designed to prevent deformation of the mesh package.

8 rotor and retrofit rotate with guide vanes 28, which can be made by bending the wall of cylinder 12.

The device works as follows.

The gas-liquid flow through the inlet 3 flows tangentially into the vertical cylindrical body 1, whereby the flow makes circular movements in the body 1. Under the action of centrifugal force, liquid drops are thrown onto the walls of the body 1 and flow into the condensate collector 5, and the initially cleaned compressed gas flows in a spiral the cavity of the inner tube 2 and along the guide vanes 28 to the slits 13.

Through the slots 13, a stream of compressed gas enters the cylinder 12, driving the turbine wheels to rotate on one shaft 6 with longitudinal blades 24.

Compressed gas flow

The resulting rotor from top to bottom is involved, in addition to the coagulation and centrifugation processes, when it moves along a helical line (combining the translational motion of the flow with its rotation in the rotor), also in other processes.

Due to the fact that the trajectory of the flow in the G1-ed.1-paged device has a composition; 1 is a helix with a variable mean diameter, the centrifugation process is intensified with a corresponding change in the speeds and centrifugal forces due to its multiple.

The stream passing through the openings of the next disk hits the deaf wall of the next adjacent disk and is forced to change direction in order to move it further into the project of the next disk. In this case, on the impact surface of this disk, contact separation of liquid vapors in the form of a film is formed, which flows under the action of the centrifugal forces of the rotating disks to their perimeter and is thrown into the walls of the cylinder 12 as drops.

The degree of separation cleaning of the flow when it hits the contact surface of the disk, followed by changing the direction depends on the distance between adjacent disks and is determined depending on the required degree of cleaning, taking into account that the flow cross-section in the holes of the disks is not smaller cross-section of the inlet 3.

The separated dropping liquid through the holes 15 of the cylinder 12 enters the chamber 14, then flows into the intermediate condensate collector 16, and from it through the drain pipe 18, the hydraulic lock 20 - into the condensate collector 5, from which the liquid components are periodically transferred through the junction box 21.

liquid recovered from gas is protected from secondary entrainment with compressed gas by barriers 22 and 23.

In the initial period of operation of the device or when it stops, when the rotor blades 8 do not yet have the required rotational speed, part of the dropping liquid can get into the end condensate collector 17. And in this case, the separated liquid through the drain pipe 19 through the hydraulic lock 20 enters the condensate collector 5 .

The proposed device makes it possible to use all three basic methods of separating drops and vapors of moisture and oil (centrifugal, coagulation-centrifuged, and separation-contact — when the flow collides with the surface of the disks, followed by a change in. Speeds and voltages) and therefore to provide a higher degree of purification of compressed gas from liquid components, i.e. increase the trapping rate of these components.

In addition, with this design, the process of coagulation and centrifugation of moisture-oil vapors from the compressed gas stream is intensified due to the fact that the stream repeatedly crosses the packet grids in different directions as its velocities and vectors change.

}) Direct the flow of compressed gas directly to the blades of the turbine wheel, as a result of which the longitudinal slots on this cylinder can be of a non-tangential type, which simplifies their manufacture, and large in cross section, which ensures a reduction in the differential pressure of the flow in the structure.

Additional benefits include ease of manufacture, ease of operation, adjustment and repair, reduced weight at the same, as compared with the serial model; a) performance.
