Common disadvantages of the technical solutions indicated in the previous paragraphs are:

- the process of eliminating the secondary ablation - aerosol liquid after passing through the separation packet by the gas stream is not sufficiently organized, namely, the processes that occur on the interface are not taken into account, which leads to a decrease in the overall separation efficiency;

- the separation of the separated liquid and mechanical solid state contaminants from the surfaces of the bottoms, made in the form of disks located under the separation bags in the separation zone, is not organized, which, due to their prolonged presence on the disks, leads to secondary entrainment and the occurrence of additional load of the separation packages, thereby reducing the overall efficiency separation.

In terms of the set of essential features and the intended use, the closest technical solution to the claimed invention is the technical solution used in the gas-liquid vertical vortex separator "SCV-8" (RF patent for utility model No. 71560, IPC B01D45 / 02, B01D45 / 16, B01D45 / 18, 2006) containing a vertical cylindrical body, upper and lower bottoms (covers), inlet, outlet, drain pipe, guiding chipper (deflector), tangential-blade swirl (separation device), characterized in that The housing directly in front of the guide chipper from the side of the incoming flow additionally contains a fairing in the form of one or more vertical plates, deployed towards the incoming stream. From the bottom to the swirl, a device for quenching the upward flow is rigidly fixed, from the bottom to which an anti-swirl is fixed.

The disadvantage of this technical solution is the connection of the outlet pipe directly to the output of the separation package. This leads to the secondary ablation of the aerosol liquid after the separation stream passes through the gas stream; processes that occur on the interface are not taken into account. This, in turn, leads to a decrease in the overall separation efficiency.

An object of the invention is to increase the separation efficiency.

The technical result of the invention is to eliminate the secondary ablation of aerosol liquid.

The essence of the invention lies in the fact that the centrifugal gas-liquid separator contains a vertical cylindrical body with upper and lower bottoms, inlet, outlet and drain pipes. A guiding chipper and a vertical tangentially vane swirler are rigidly fixed in the housing. From the bottom to the swirl, a device for quenching the upward flow is rigidly fixed. From below, an anti-swirl is fixed to the blanking device. It differs in that the anti-swirl is made in the form of intersecting vertical plates. Above the swirl is placed the lower plate with a confuser, over which the upper plate with a diffuser is placed. The confuser and diffuser are made cylindrical or conical and placed coaxially to the swirl with an annular gap to each other. The bottom end of the confuser is located below the bottom plate. At least one lower cheek is fixed in the space between the plates on the lower plate.

The above essence is a set of essential features of the claimed technical solution, ensuring the achievement of the claimed technical result.

In special cases, it is permissible to carry out the technical solution as follows.

The swirler is preferably cylindrical and contains vertical curved plates fixed to the lower plate so that the swirl axis is offset relative to the vertical axis of the housing away from the guide bump. The quenching device can be made in the form of a cone with an angle at the base of not more than 50 degrees and preferably rigidly fixed to the swirl with radial plates at a distance of 0.05 to 0.2 swirl diameter.

The lower end of the confuser is located mainly below the lower plate by a distance of up to 0.5 of the diameter of the outlet pipe. The annular gap between the confuser and the diffuser is from 1 to 10 mm. Plates can be in the form of a disk or cone with an angle at the base of up to 25 degrees. The upper plate is preferably provided with cutouts forming gaps with the inner wall of the cylindrical body.

It is permissible to fix two lower cheeks in the space between the plates on the lower plate, and two upper cheeks on the upper plate. The cheeks are made in the form of flat plates, and the angle between any upper and any lower cheek is 90 degrees.

The centrifugal gas-liquid separator contains a vertical cylindrical body 2 (Fig. 1) with upper 41 and lower 42 bottoms, inlet 1, outlet 24 and drain 12 nozzles.

The inlet pipe 1 is located in the upper part of the separator. The axis of the inlet pipe 1 can intersect the center line 44 of the housing 2 (Fig. 2, 3) or can be offset horizontally relative to it (Fig. 4, 5, 13).

At the inlet pipe 1 to the housing 2, a guide bump 4 with arcuate distributor plates 5 (Fig. 3, 7, 8) is rigidly fixed to prevent direct gas-liquid mixture entering the axial zone of the apparatus and giving the gas-liquid flow an initial rotational movement, as well as the necessary speed indicators . Distribution plates 5 also provide rigidity and strength of the guide bump 4 when exposed to gas-liquid flow.

A vertical tangential-vane swirler 14 is rigidly fixed in the casing 2. Its axis 43 is shifted relative to the vertical axis 44 of the casing away from the guide bump 4 (Fig. 2), which helps to reduce the hydraulic resistance of the separator. The axis displacement is calculated in accordance with the required gas-dynamic characteristics of the separator. The swirl 14 has a cylindrical shape and consists of vertical curved plates 22 directed towards the incoming stream (Fig. 8). In the overlapping zone of the plates 22, identical slot channels 21 are formed. The area of the slot channels 21 decreases from the periphery of the tangential-blade swirler 14 to its axis, which helps to reduce the hydraulic resistance of the separator. The bottom of the plate 22 is fixed to the annular base 18, and the top to the bottom plate 6. The rigidity of the design of the swirl 14 is increased due to its twisting from the outer and / or inner side in a spiral metal wire 40 (Fig. 1), fixed to the plates 22.

Bottom to the tangential-blade swirl 14 through the radial plates 19 is rigidly attached to the damping device of the upward flow 11, made in the form of a cone with a slope angle (angle at the base) of not more than 50 degrees. The distance between the swirl 14 and the blanking device 11 is from 0.05 to 0.2 of the diameter of the swirl 14. The distance is measured along the vertical line between the plane of the base 18 of the swirl 14 and the nearest point of the blanking device 11 (the top of the cone). Radial plates 19 are simultaneously designed to prevent the rotational movement of the gas (air) stream and to ensure free flow of liquid onto the quenching device of the upward flow 11. The axis of the conical surface of the quenching device 11 can be either parallel or coincide with the axis of the cylindrical separator body 2. The cone of the extinguishing device 11 forms an annular channel 10 with the inner wall of the cylindrical body 2 for transporting droplet-aerosol and film liquid, as well as mechanical solid state contaminants, from the separation zone to the drain pipe 12.

A cruciform anti-swirl 20 made of intersecting vertical plates is fixed to the suppression device 11 below (Fig. 1, 10). The anti-swirl 20 is designed to prevent the vortex movement of the gas (air) flow under it.

At the drain pipe 12 to the casing 2 of the separator, the funnel breaker 13 (Fig. 1, 11) is rigidly fixed, made in the form of one or more intersecting vertical plates and a cover with an outer diameter 1.5-2.5 times the diameter of the drain pipe. The funnel breaker 13 is designed to prevent the creation of a liquid funnel and the breakthrough of the gas (air) phase in the drain pipe 12.

A fairing 15 is also mounted inside the separator, consisting of one or more vertical curved plates mounted in the direction of gas-liquid flow. The figure 8 shows the fairing 15, containing one plate, forming with the housing 2 a slot-like opening 16 with a width of not more than 10 mm The fairing 15 is designed to reduce the hydro-gas-dynamic load on the internal devices by giving the gas-liquid flow a smooth path in the space formed by the cylindrical body 2, the vertical tangential-blade swirler 14 and the guiding chipper 4. This reduces the hydraulic resistance of the separator. At the same time, the fairing 15 together with the rear wall of the guide chipper 4 forms a trap 17 for trapping and transporting droplet-aerosol and film liquid, as well as mechanical solid-state contaminants in the supply compartment - in the space of the separator below the lower plate 6.

The lower plate 6 with the confuser 23 installed in it and the upper plate 26 located above it with the diffuser 25 installed in it are rigidly fixed to the separator body 2 (Fig. 1). The lower and upper plates divide the inner space of the separator into three compartments:

- supply 39 - compartment below the lower plate 6,

- drain 28 - compartment between the plates 6 and 26,

- outlet 36 - compartment above the upper plate 26.

The confuser 23 and the diffuser 25 are cylindrical or conical and mounted coaxially with the vertical tangential-blade swirl 14 (Fig. 1, 2, 3, 6, 7). The conical confuser and diffuser can be oriented relative to each other by any possible means. In particular, they can be located with the smaller bases of the truncated conical surface upward or with smaller bases to each other. The lower end of the confuser 23 is located below the lower plate 6 by a distance of up to 0.5 of the diameter of the outlet pipe 24 to minimize stalling of the droplets in the moving dispersed layer and their return to the cleaned gas stream. Plates 6 and 26 may be in the form of a horizontal disk or cone with a slope angle of up to 25 degrees. The upper plate 26 is provided with cutouts forming gaps 35 with the inner wall of the cylindrical body 2. The gaps 35 are designed to lead part of the gas from the drain compartment 28 to the discharge compartment 36. The lower 6 and the upper 26 plates are located one above the other so that between the ends of the confuser 23 and the diffuser 25 is provided with an annular gap 27 from 1 to 10 mm for removal through it of the residues of suspended particles carried away by a gas (air) stream.

In the space of the trap 17, a drainage tube 32 is installed. The upper end of the drainage tube 32 is rigidly fixed in the drainage hole 31 of the lower plate 6 to remove accumulated liquid and mechanical solid impurities from its surface. To increase rigidity along the entire length of the drainage tube is equipped with mounting scarves 33, fixed to the housing 2 (Fig. 8).

The separator is equipped with a screen 34 made in the form of a curved plate and located under the guide chipper 4 in the area of the lower edge of the trap 17 and the drain pipe 32 (Fig. 10, 11). The screen 34 isolates the area of liquid and mechanical solid-state contaminants exit from the drainage tube 32 and the trap 17. In the particular case, the screen 34 can be made integral with the guide chipper 4 and be a continuation of the chipper 4 down by the required amount.

In the drainage compartment 28, the lower guide cheeks 30 are fixed to the lower plate 6, and the upper guide cheeks 29 made of curved or flat plates are fixed to the upper plate 26 (Figs. 1, 6, 7). The height of the plates is less than the height of the drainage compartment. The cheeks 29 and 30 are designed to prevent circular movement of the gas flow in the drainage compartment, enlarge the suspended particles and transport them to the drainage tube 32. The cheeks are installed so that between each pair of the nearest lower 30 and upper 29 cheek there is an angle of no more than 90 degrees. One of the lower cheeks 30 is located near the drainage hole 31. In the guide cheeks located on top of the lower plate 6 in their central part, gaps are made for the unimpeded transportation of the liquid film and mechanical solid impurities to the drainage tube 32.

When implementing the separator for conditions of low content of droplet aerosol liquid and mechanical solid-state contaminants in the incoming gas-liquid flow, it is allowed to limit oneself to installing one guide cheek 30 on the lower plate 6, which is installed closer to the drainage hole 31.

Examples of specific performance.

Example 1. The axis of the inlet pipe 1 and the outlet pipe 24 are placed in the same horizontal plane perpendicular to the axis of the casing 2 of the separator. In this case, the inlet pipe 1 is located above the upper plate 26. To prevent the gas-liquid flow from the inlet pipe 1 immediately into the outlet compartment, the guiding chipper 4 is closed from above by a cover 7 made in the form of a sector, and from the side by a rectangular plug 8. The height of the plug 8 corresponds to the distance between the cover 7 of the chipper and the lower plate 6. In the particular case of execution from below, the space between the housing 2 and the chipper 4 can be closed by the bottom 9 of the chipper, made in the form of a sector.

Example 2. The separator is made analogously to example 1. To ensure compliance with the binding characteristics of the head installation, the inlet pipe 1 and the output pipe 24 are placed coaxially (Fig. 3). The axis of the nozzles 1 and 24 are perpendicular to the axis of the housing 2 of the separator.

Example 3. The separator is made analogously to example 1. To ensure compliance with the binding characteristics of the head installation, the inlet pipe 1 and the outlet pipe 24 are placed so that their axes are parallel (Fig. 4). The axis of the inlet pipe 1 is offset horizontally relative to the axis of the separator housing, and the axis of the outlet pipe 24 is perpendicular to the axis of the housing 2 of the separator.

Example 4. The separator is made analogously to example 1. To ensure compliance with the attachment characteristics of the head installation, the inlet pipe 1 and the outlet pipe 24 are placed so that their axes are angled to each other. In the particular case shown in figure 5, these axes are perpendicular. The axis of the inlet pipe 1 is offset horizontally relative to the axis of the separator housing, and the axis of the outlet pipe 24 is perpendicular to the axis of the housing 2 of the separator.

Example 5. To ensure compliance with the attachment characteristics of the head installation, the inlet pipe 1 is placed horizontally (Fig. 12, 13), and the outlet pipe is placed vertically in the upper bottom (not shown). The axis of the inlet pipe 1 is shifted horizontally relative to the axis of the separator housing, and the axis of the outlet pipe is located on one straight line with the axis of the separator body. The inlet pipe 1 is located below the lower plate 6. On top of the guide bump 4 is connected to the lower plate. Below the space between the housing 2 and the chipper 4 is closed by the bottom 9 of the chipper. The separator according to this example has a lower height compared to the separator according to example 1 at the same speed performance.

Example 6. For the purpose of highly efficient separation of a gas-liquid stream with a low gas factor, the output part of the guide chipper 4 has an edge 37 bent towards the center of the separator at an angle of 5 to 30 degrees (Fig. 9). The specified bending angle is measured between two planes, one of which is tangent to the edge of the bump 4, and the second is tangent to the body 2 on the projection of the edge of the bump 4 on the body. Moreover, the cross-sectional area of the output slit-like channel 38, formed by the housing 2, the guiding chipper 4 and its cover 7 and the bottom 9, is smaller in comparison with the analogues of the technical solution to create the conditions for the occurrence of hydrodynamic cavitation.

The implementation of the structural elements of the claimed invention is not limited to the above examples.

As illustrated by the above examples, the internal layout of the separator eliminates the disadvantage of analogues, which consists in the limitation of the possible methods of connecting the separator to the head unit.

The inventive separator operates as follows.

Gas containing droplet-aerosol liquid and mechanical solid-state pollution (gas-liquid flow) is supplied to the separator through the inlet pipe 1. A guiding chipper 4 with arcuate distribution plates 5 is applied to the gas-liquid flow in a rotational-translational motion with the formation of a centrifugal field.

Under the action of centrifugal force, droplet liquid and mechanical solid state impurities, which have a much higher density than gas (air), move to the periphery (inner wall) of the cylindrical body 2 and settle on it, forming a liquid film. The liquid film flows down the inner wall of the cylindrical body 2 in a downward spiral through the annular gap 10 to the lower part of the separator, from where it is discharged through the drain pipe 12.

The funnel breaker 13 prevents the organization of the circular motion of the liquid.

The trap 17 picks up the liquid film from the inner wall of the cylindrical body 2, while the fairing 15 acts as a remover of the liquid film. Caught liquid and mechanical solid impurities are transported by gravitational forces to the lower part of the separator.

Fine-dispersed (aerosol) liquid that has not settled on the inner wall of the cylindrical body 2 is transported by a gas (air) stream to a vertical tangential-blade swirler 14, in which there is an additional swirling of the gas (air) stream due to the presence of a set of tangential slotted channels 21. Due to the sequential overlap vertical curvilinear plates 22 to each other formed dispersion-ring mode of flow of gas-liquid flow. The liquid film on the inner surface of the vertical curved plates 22 is held by centrifugal force. The liquid film formed in the lower part of the vertical tangential-vane swirl 14 is transported through the annular base 18 to the upstream quench device 11. The suspended particles move in the vertical direction due to the axial movement of the gas-liquid flow and are collected in the upper part of the vertical tangential-vane swirl 14 under the lower plate 6 at the periphery of the confuser 23.

Radial plates 19 prevent the rotational movement of the gas (air) stream and provide free flow of liquid to the quenching device of the upward flow 11.

From the surface of the quenching device of the upward flow 11, the liquid flows to its edges and then through the annular gap 10 is transported to the lower part of the separator.

The anti-swirl 20 prevents the swirling movement of the ascending gas (air) stream, which excludes the rise of the liquid fraction accumulated below it.

Residues of suspended particles carried along with the gas (air) stream through the confuser 23 and the diffuser 25 are captured by a slit-like annular gap 27 and fall into the drainage compartment 28. There they are enlarged due to inertia forces arising from a sharp change in the direction of movement of the gas stream caused by the installation of guides cheeks 29 and 30.

Part of the gas stream, which, together with suspended particles, enters the drainage compartment 28 through a slit-like annular gap 27, is collected in its upper part under the upper plate 26 and is discharged through the gaps 35 into the exhaust compartment 36. The completely purified gas from the exhaust compartment 36 is discharged from the separator through the outlet branch pipe 24.

The claimed invention can be manufactured at any industrial enterprise and will find its wide application in industry.
