The invention relates to the purification of gases from liquids, such as water, oils, hydrocarbons, moving in systems under the action of excess pressure, and can be used to improve the reliability and durability of the transport pipeline systems, as well as the operation of automation systems.

The known method (1) separation of the liquid in dispersed flow, consisting in the creation of the swirler twisted in mutually opposite directions of internal and external flows, where dehumidification is on the inner surface of the shell by the action of inertia forces. Moreover, the deviation from alignment causes strengthening effect. However, there is no separation of the vaporous portion of the moisture, nor to provide efficient removal of the liquid phase of the working volume.

The known method (2) separation of the liquid in dispersed flow, which consists in twisting of the flow dispersion medium in separating the ring with a swirl, flow mesh shell, the Department and the evacuation of fluid through the perforated forming shell when creating a differential pressure on it. However, not separated all the liquid and efficiency can significantly influence the temperature at the inlet, a significant increase which dramatically reduces the separation of liquids.

The known method (3), privatize closest analogue, namely, that the separation occurs when the forward and backward movement of the flow respectively in separating external and internal shells, pre-twisted swirlers, transportation of liquid on the peripheral forming shells when creating a differential pressure on them, bootdelay liquid and vapor phase filters installed in additional cowling, with coalescing and sorbing properties, regeneration latest ottovon heated air. Moreover, the intensity of separation increases with podgladanie dispersion medium at the inlet swirl on heat bridge linking pricebuy the area of additional shell with a volume between them. However, the absence of thermal stabilization leads to fluctuations in the content of the liquid and vapor phases in the flow of the dispersed environment, which complicates the operation coalescense and absorptive filters, and reduces the efficiency of the separation.

Analysis of the above prior art suggests that the object of the invention is to increase the efficiency of separation of the disperse medium.

This is achieved by the fact that the share of dispersed flow with the preliminary cooling down, volume separating and additional shells and collections when vipasyana separating shells by evaporation of a part of the condensed moisture di is dispersed environment on the developed cylindrical surface drainage Windows capacitors, made of highly porous cellular metals and coaxially installed with the software gapless fit to the inner forming and separating additional shells and the formation of thermal bridges, disable the bypassing serves stream in an additional shell, separating the condensed moisture on the developed surfaces of the capacitors with their simultaneous podgladanie during its evaporation.

Figure 1 and 2 presents a diagram of the device for implementing the method.

The device includes a housing 1 with a cover 2 and the flange 3, is supplied with the input 4 and output 5 nozzles, coaxial located external separator 6 and the internal option 7 shells with capacitors 8, 9 and the respective swirler 10, 11, disk diaphragms 12, 13, reticulated shells 14, 15 and the filters 16, 17 with coalescing and sorbing properties. Cover 2 is supplied by a pipe 18 with the valve 19 associated with the bypass 20 to provide preliminary tahaliyani volumes separator 6 and more 7 shells and collections 27, 28 sets 29, 30 of annular elements of a highly porous cellular metals (open porosity of up to 95%). Shell condensers 8, 9 are made of a highly porous cellular materials with cylindrical developed lateral surfaces 21 to 25 and then drain the Windows 22 and installed coaxial is to ensure gapless fit to the inner forming separator 6 and more 7 shells and the formation of thermal bridges, linking intensively cooled volumes capacitors 8, 9, separator 6 and more 7 shells and cylindrical shell 23. To reduce external heat gains outer surface 44 of the housing 1 is made of insulated. Separator 6 and more 7 shell provided with housings 24, 26 with the formation of cavities collections 27, 28 placed in them sets of ring elements 29, 30 of high porous foam metal contact on the bottom end surface with Zoologicheskii elements of thermal bridge, which prevents the evaporation of the condensed and collected moisture from collections 27, 28, and serves as the batteries are cold. Forming a separator 6 and more 7 shells made perforated, and to ensure that the differential pressure on them they relate reducing the lads 31 and 32, one end of which is located in the axial rarefied zone flow, and the other has access to the specified 27 and 28 in order to create the vacuum. Podgladanie output is carried out by thermal bridge, a cylindrical shell 23 which is provided on the outer coaxial shell 33 of highly porous foamed metal having coalescent properties and installed in the paraxial zone of the additional shell 7 and fastened it on insulated pylons 34. Took the I filter regeneration 17 sorbing properties of the outlet 5 to the valve 35 provided with outlet 36 with the valve 37, and the amount of additional 7 shell - pipe 38, valve 39 for Ottawa heated air. Collections 27, 28 is equipped with nozzles 40, 41 with the valves 42, 43 to drain the fluid. The filters 16, 17 with coalescing and sorbing properties made of highly porous polymeric materials-spatial globular structure.

The method is as follows.

For pre-Sahelian device overlaps the outlet 5 of the valve 35 opens the valve 19 bypass pipe 18, the flow of the dispersion medium is fed into the annular space between the casing 24 and separating drum 6 through the inlet pipe 4, which tightened the ring aperture 12, is separated from the condensed moisture on the net cowling 14 and twists swirler 10. Under the action of inertia forces the liquid is discarded on the side surface of the condenser 8, where by vacuum at 25 and then drain the Windows 22 of the highly porous metal capacitor 8 and the perforations saariluoma shell 6 is partially evacuated to the collector 27, and partly flow speed is made in the bypass line 20, subjected to evaporation on the developed surface of the capacitor 8, Shalaeva thermal bridges volumes separator 6 and more 7 shells, cylindrical shell 23, the volume of collections 27, 28 sets of ring elements 29, 30 of high porosity is porous metals, who are filled with condensed moisture, which is a good coolant, and accumulate cold. After tahaliyani bypass 20 is turned off, closes the valve 19 and opens the valve 35 of the outlet pipe 5. The flow of the dispersion medium is supplied via the inlet pipe 4 into the annular space between the casing 24 and separating the shell 6, which tightened the ring aperture 12, is separated from the condensed moisture on the net cowling 14 and twists swirler 10. Steam, the moisture in contact with developed surfaces cooled condenser 8, effectively condenses and then drain the Windows 22 of the last 8 and flows through the perforations separating the shell 6 in the collector 27. The remaining part of the steam moisture in the stream when podgladanie line separating the shell 6 is partially condensed. Dispersed flow takes place on a profiled bore of the cover 2 and is fed into the annular space between the casing 26 and an additional 7 cowling, which also tightened the ring diaphragm 13, on the net cowling 15 separates the formed condensate, podrachivala swirler 11, drip fraction, as centers of condensation, actively converts vapor into liquid fraction developed on the cooled surfaces of the capacitor 9 and filter coalescing properties 16 and coaxial porous is the ring 33 of the cylindrical shell 23, the remainder of the vapor phase separated in the filter 17 with sorbing properties. Regeneration the last 17 is in closed valves 19, 35, 42, 43 and open the valves 37, 39 ottovon heated air. After regeneration produce preliminary cooling down the device.

The use of the proposed method due to the stabilization and prior to the accumulation of cold in the developed volume with good heat and mass transfer properties of capacitors, collections with a fluid, a cylindrical shell, made with the use of highly porous cellular metals can significantly reduce the fraction of the vapor phase, expanding the possibilities of removal of condensate, and thereby increase mainegenealogy period filter with sorption properties in a more complete separation of the disperse medium.
