Each of said separators includes: a vertical cylindrical housing, a housing cover, a housing bottom, an inlet port, an outlet port, a particle outlet port, a deflector, and a vertical separation pack. The separating package consists of vertical S-shaped separating plates, which form slot channels in overlapping zones. The separation devices also have upper and lower thrust washers located in the lower part of the separation pack and connected to radially directed plates.

The disadvantage of the known separation devices is a resumption of the separated liquid at the upper axial disk from the purified gas stream. This reduces the effectiveness of the deposition.

It is an object of the invention to increase the rate of liquid discharge from the surface of the axial discs and thus the effectiveness of the deposition process in the separator.

The essence of the invention is that the separation device comprises the following elements:

• a) a vertical cylindrical housing,
• b) a housing cover,
• c) a housing bottom,
• d) an inlet nozzle,
• e) an outlet nozzle,
• f) a particle outlet nozzle,

• h) a separating package of vertical S-shaped plates,
• i) an intermediate floor and
• j) flow straightener with an upper and a lower axial disk, wherein the axial disks are connected to each other with Strömungsglätterplatten.

The effectiveness is increased by the fact that the flow straightener plates are formed with a curvature along the movement of the eddy current around the separation package.

The flow straightener plates can be perforated. The flow straightener plates may be disposed between the axial discs at a radial distance from the vertical axis connecting the centers of the axial discs ( 5 ).

The invention will be explained in more detail with reference to an embodiment shown in the drawings. Show it:

1 a separator scheme in longitudinal section AA,

2 a separator scheme in cross-section BB,

3 a separator scheme in cross-section CC,

4 a perforated flow straightener plate and

5 a Strömungsglätterplatte with a distance to the cross section BB after 1 ,

The separating device according to the vortex principle ( 1 . 2 . 3 ) comprises: a vertical cylindrical housing 1 , a housing cover 2 , a caseback 3 , an inlet nozzle 4 , an outlet 5 , a particle outlet 6 , a deflector 7 with a baffle plate 8th , a separation package 9 and an intermediate floor 10 ,

• – eine Ableitung der Flüssigkeit und der festen Partikel in den unteren Sammelteil der Abscheidevorrichtung.

The deflector 7 is next to the inlet pipe 4 arranged. The deflector 7 serves to displace the gas flow into a rotating (vortex-like) movement within the separation device. The inner wall of the housing 1 , the deflector 7 and the flapper 8th form a discharge chamber 11 which is intended for the following purposes:

• - A derivative of the moving liquid and the solid particles from the eddy current, by the centrifugal force to the inner wall of the housing 1 the separator are pressed and
• - A derivative of the liquid and the solid particles in the lower collection part of the separator.

The particle outlet nozzle 6 is on the case back 3 the deposition device arranged.

The separation package 9 has cylindrical shape and consists of S-shaped separating plates 12 , which form its mantle surface. These dividing plates 12 make slits 13 in the overlay zones whose size remains constant along their length. Below are the separator plates 12 on the flow straightener 16 firmly attached The flow straightener 16 consists of a lower and an upper axial disc 14 and 15 passing each other through curved flow straightener plates 16 are connected. The flow straightener plates 16 serve to prevent a vortex-like movement of the gas flow under its arrangement zone. The flow straightener plates 16 are with a curvature along the movement of the eddy current around the separation package 9 executed. The authors have found that by the described shape and the direction of curvature of the plates of the flow smoother 16 a negative pressure at the outer edge of the Strömungsglätters 16 relative to the central area of its interior 17 arises. The plates of the flow straightener can do this 16 be perforated ( 4 ). The plates of the flow smoother 16 may be at a radial distance from its vertical axis, which are the centers of the axial discs 14 and 15 connects ( 1 ), the lower axial disc 14 with N pins 18 firmly attached. The ends of the pencil 18 are dense, but displaceable, along its vertical axis in openings of the false bottom 10 stored. The intermediate floor 10 is with an annular gap 19 to the housing 1 arranged and attached with the help of L-shaped plates 20 firmly attached.

The proposed separator works as follows:
The gas stream to be cleaned is through the inlet port 4 introduced into the separation device. The deflector 7 changes its direction and forms a rotating movement of the gas flow around the separation package 9 ,

In the space between the wall of the housing 1 and the separation package 9 The main part of the liquid and the solid particles collects and is applied by the centrifugal force to the wall of the housing 1 pressed the separator. Under the action of gravitational force, the liquid and solid particles move along the wall of the housing 1 spiral down in the direction of the rotation of the gas flow. In this case, a part of the liquid and the solid particles gets into the discharge chamber 11 and sinks down the wall to the false floor 10 , After reaching the false floor 10 the liquid and solid particles enter the annulus 19 between the case 1 and the intermediate floor 10 and become the particle outlet 6 derived.

The finely dispersed liquid distributed in droplets, not on the wall of the housing 1 arrives at the outer surface of the S-shaped partition plates 12 and gets from the gas flow through the slots 13 transported to their inner surfaces. There she runs along the partition plates 12 downward. From the lower edges of the separator plates 12 The liquid particles slide off, come to the surface of the false floor 10 and are through the annular gap 19 between the case 1 and the intermediate floor 10 to the particle outlet 6 derived.

Part of the liquid reaches the surface of the upper axial disc 15 and flows into the interior 17 of the flow smoother 16 and through its central opening. The shape and the direction of curvature of the plates of the flow smoother 16 cause the pressure in the central area of the interior 17 of the flow smoother 16 is greater than at its outer end. This pressure difference increases the rate of liquid discharge from the central area of the interior 17 of the flow smoother 16 to the outer edge of the lower axial disc 14 , This reduces the likelihood of resumption of the liquid from the riser flow of the purified gas. The fluid flows from the outer edge of the lower thrust washer 14 on the shelf 10 and off through the annular gap 19 between the case 1 and the intermediate floor 10 to the particle outlet 6 derived.

The purified gas stream enters the outlet port 5 ,

The declared technical result of the invention "increasing the rate of liquid discharge from the surface to the axial discs" is achieved in that the device for separating particles from a gas flow according to the vortex principle comprises: a vertical cylindrical housing 1 , a housing cover 2 , a caseback 3 , an inlet nozzle 4 , an outlet 5 , a particle outlet 6 , a deflector 7 with a baffle plate 8th , a vertical separation package 9 , Flow straightener 16 and an intermediate floor 10 , The separation package 9 consists of vertical S-shaped dividing plates 12 , The flow straightener 16 consists of a lower one 14 and an upper one 15 Axial disc, which overlap each other via curved plates of the flow straightener 16 are connected. Here are the plates of the flow straightener 16 with a curvature along the movement of the eddy current around the separation pack 9 executed.

The proposed separation device can be produced with materials produced by the industry, can be used in any mechanical engineering company can be widely used in oil, gas, chemical and other industries.
