The gas vortex type separator (Fig. 1) contains a vertical cylindrical body 1, upper 2 and lower 3 bottoms; input 4, output 5 and drain 6 nozzles; a deflector-swirl 7 with a baffle plate 21 (FIGS. 2, 3) and a catch pocket 24 (FIGS. 2, 3); two conical support discs 9 and 10 hermetically fixed in the housing; a drainage tube 18 with a drainage hole 17 (FIG. 2); separation bag 14 with a solid conical base 15 and concentric rings 12 and 13.

Two cone-shaped supporting disks 9 and 10 divide the inner space of the separator into two chambers: a vortex chamber 23 from below and an additional chamber 22 from above.

In the hole of the cone-shaped supporting disks 9 and 10, located coaxially with the separation package 14, the inner rings 11 are rigidly fixed with gaps h of equal size between them. Preferably, the number of rings 11 is three. The rings are rigidly interconnected by connecting plates 27 (FIGS. 4 and 5), forming a block of rings.

On the lower support disk, inside the separation bag, two concentric rings are fixed - upper 12 and lower 13.

 Inlet 4 and outlet 5 nozzles are aligned. These nozzles are normally fixed in the cylindrical case 1 of the separator in the area of the additional chamber 22. The drain pipe 6 is located in the lower bottom 3 of the separator (figure 1).

The deflector-swirl 7 is located at the inlet 4. The outlet 25 of the deflector-swirl 7 is located in the vortex chamber 23. The deflector-swirl 7 is provided with a baffle plate 21 (Fig. 2) and is designed to form a rotational (vortex) movement of the gas flow in the vortex chamber 23 separator. The deflector 7 also prevents the flow of gas into the additional chamber 22 and into the axial zone of the vortex chamber 23 without prior separation.

The inner wall of the housing 1, the deflector-swirl 7 and the reflective plate 16 form a catch pocket 24 (2, 3. The disk 9 is not shown conditionally). Pocket 24 is designed to remove from the vortex flow of moving fluid particles and mechanical impurities pressed by centrifugal force to the inner wall of the separator housing 1, and their transportation to the lower storage part of the separator.

The separation bag 14 is used for fine purification of a gas-liquid mixture.

The separation package 14 is made in the form of an inverted truncated cone and contains curved separation plates 26 located in its forming surface and forming identical and constant size slotted channels in the lap zone. Curved plates 26 are rigidly fixed in the upper part to the lower support disk 10, and in the lower part to the conical base

15 (FIG. 1). Preferably, the conical base was solid, without holes. This design allows you to avoid unhindered liquid in the separation package from the Central zone of the vortex chamber and the accumulation of fluid on its inner surface.

The separation package 14 is located in the axial zone of the separator so that its axis is parallel to the axis of the cylindrical body 1 of the separator and is offset relative to it in the direction from the deflector 7 by a distance ε so that the axis of the separation package is located at an equal distance from the deflector-swirl 7 and the inner wall case 1 of the separator.

Two concentric rings 12 and 13, mounted on the lower support disk 10, in the area of the separation package 14, form a two-stage obstacle to the movement of fluid.

The separator contains a vertical drainage tube 18 located in the catch pocket 24. One end of the drainage tube 18 is fixed in the drainage hole of the lower support disk 10 (not shown), and the other end is fixed in the compensator of the hydraulic shutter 20. The drainage tube hydraulically connects the additional chamber 22 with the vortex camera 23 (figure 1).

The separator may be further provided with a spiral plate 19 located in the lower part of the separator.

The spiral plate 19 is designed to prevent the vortex flow in the installation zone and the direction of the fluid particles from the separator wall to the drain pipe 6, the radius of its turns decreases when the spiral is circumvented in the course of the vortex gas movement in the vortex chamber 23.

Work.

The inventive gas vortex type separator operates as follows.

A gas-liquid stream with an increased amount of liquid, which must be cleaned of liquid and mechanical impurities, is supplied from the pipeline to the separator through the inlet 4. By means of a deflector-swirler 7, the gas-liquid stream is given the necessary acceleration and direction of motion, which allows you to set the necessary gas-dynamic characteristics for the formation centrifugal principle of gas separation.

The deflector 7 smoothly changes the direction of gas movement and forms its vortex motion around the separation package 14 in the vortex chamber 23.

At the exit 25 of the deflector-swirl 7 (Fig. 3), due to an increase in the cross-sectional area and the volume of the separator, the gas-liquid flow velocity decreases, and the fluid moving along the inner wall 8 of the deflector-swirl 7 (Fig. 1, 2, 3) , tends to move to the center of the vessel in the form of droplets or a finely divided fraction, where, picked up by the oncoming gas stream, it can be transported to the zone of the separation package 14, thereby creating an additional liquid load in the fine cleaning zone. To eliminate this phenomenon, a baffle plate 21 is provided in the design of the deflector-swirl 7 (FIGS. 2, 3), which not only prevents liquid separation in the velocity change section, but also additionally forms a liquid flow, pressing it against the inner surface of the separator body wall.

In the space formed by the wall of the housing 1 and the separation package 14, the bulk of the liquid and mechanical impurities are released from the gas stream. The main amount of liquid and mechanical impurities are discarded by centrifugal force on the walls of the separator housing 1 and move along it in the direction of rotation of the gas stream, where it enters the collecting pocket 24, and flows under gravity to the drain pipe 6.

The aerosol fraction of liquid and mechanical impurities, which did not settle due to the low specific gravity on the wall of the housing 1, mixes and enters the outer surface of the curved plates 26 of the separation bag 14 and is transported by gas flow through the slotted channels to their inner surface. Rising along the inner surface of the plates, due to the lifting force of the upward gas flow, but at a low speed (not more than 1 m / s), the mixture of liquid and mechanical impurities, increasing in volume and mass, approaches the point of attachment of the separation package 14 and the lower supporting disk 10 and concentric ring 13. Trying to overcome the slope of the cone-shaped supporting disk 10 and the obstacle of the ring 13, most of the liquid, due to its mass, falls down onto the surface of the solid conical base 15 and due to its slope is removed from the region Asti separation bag. Further along the movement of the remaining liquid and after separation on the ring 13, a similar action occurs at the boundary of the ring 12 and then on the lower ring 11 of the pipe. Particles of fluid fall into the lower region of the vortex chamber.

The remnants of the liquid in the form of a film try to rise up, clinging to the wall of the lower and middle rings 11 of the pipe, but due to the gaps between them are diverted to the region between the two supporting disks 9 and 10, and due to the conical shape, as well as due to centrifugal speed and increase own masses are transported to the area of the drainage hole 17 of the tube 18, through which they enter through the damper 20 compensator to the drain pipe 6.

In the lower region of the vortex chamber, a spiral plate 19 can be additionally installed. The spiral plate 19 prevents the swirling movement of accumulated liquid in the lower region of the vortex chamber 23 of the separator and directs the liquid particles to the drain pipe 6.

 Thus, due to the multi-stage purification of a gas-liquid stream from liquid and mechanical impurities, the problem of increasing the degree of purification of a gas stream with a high liquid content is solved.

The technical result, which consists in expanding the arsenal of gas vortex type separators, is achieved by the fact that in a gas vortex type separator containing a vertical cylindrical body, divided into a vortex and an additional chamber; upper and lower bottoms; inlet, outlet and drain pipes, separation bag and drain pipe; while the inlet and outlet nozzles are aligned and normally secured in the cylindrical separator body in the area of the additional chamber; moreover, the inlet pipe is connected to the deflector-swirl, the outlet of which is located in the vortex chamber, and the inner wall of the housing, the deflector and the reflective plate form a pickup pocket, according to a useful model, the deflector-swirl is additionally equipped with a baffle plate; wherein the separator comprises upper and lower cone-shaped supporting disks hermetically fixed in the housing, dividing the inner space of the separator into a vortex and an additional chamber; at the same time, in the hole of the cone-shaped supporting disks located coaxially with the separation package, the inner rings are rigidly fixed with gaps of equal size between them; while on the lower support disk, inside the separation package, the upper and lower concentric rings are fixed; wherein the separation package is made in the form of a truncated cone and contains curved separation plates rigidly fixed in the upper part on the lower support disk, and in the lower part on a conical base.

In this case, the conical base of the separation bag is solid.

In this case, the separation package is located in the axial zone of the separator so that its axis is parallel to the axis of the cylindrical separator body and is offset relative to it in the direction from the deflector by a distance equal to half the average distance from the deflector to the separator body.

In this case, the separation package contains curved separation plates located in its forming surface and forming identical and constant size slotted channels in the lap zone.

Moreover, the separator further comprises a spiral plate located in the lower part of the separator.

In this case, the separator contains a vertical drainage tube located in the catching pocket, one end of which is fixed in the drainage hole of the lower support disk, and the other end is fixed in the compensator of the hydraulic shutter, while the drainage tube hydraulically connects the additional chamber with the vortex chamber.
