Description

[Technical Field]

[0001] The present invention relates to a compressed air water-steam separator applied to a multi-stage turbo compressor system, and more particularly to a compressed air water-steam separator applied to a multi-stage turbo compressor system that removes moisture from compressed air compressed in the multi-stage turbo compressor system to obtain and discharge optimal compressed air. [Background technology]

[0002] Compressed air is used in a variety of industries for a variety of purposes.

[0003] The compressed air is high-pressure air that has been compressed by an air compressor and reduced in volume.

[0004] In other words, it is air that has been compressed above a certain pressure to reduce its volume, and air whose density has increased due to pressure higher than atmospheric pressure.

[0005] In the process of compressing atmospheric air, moisture, oil, and various impurities contained in the air are condensed into this compressed air.

[0006] As the compressed air flows, the moisture in it turns into condensed water, which can cause serious problems in the compression system.

[0007] Furthermore, the quality of compressed air is determined by its moisture content.

[0008] That is, the lower the moisture content, the better the quality.

[0009] High-quality compressed air not only maximizes energy efficiency, but also directly contributes to improving the safety and reliability of the systems to which it is supplied.

[0010] Accordingly, an object of the present invention is to provide a moisture separator for compressed air applied to a multistage turbo compressor system capable of obtaining high-quality compressed air from which moisture has been removed.

[0011] Therefore, as a prior art related to a moisture separator for compressed air applied to a multistage turbo compressor system, as shown in FIG. 7a, Korean Registered Patent No. 10-1868915, "Trap Device of Vacuum Pump Moisture Removal System" (hereinafter referred to as "Patent Document 1") includes a housing in which a plurality of compartments are formed vertically inside; an inflow pipe inserted into the housing from the upper part of the housing to transmit air flowing in from a vacuum target to a compartment located at the lowermost stage of the housing among the plurality of compartments; trap oil filled in a plurality of compartments including the compartment located at the lowermost stage of the housing; and a filter element inserted into any one of the plurality of compartments to remove at least one of moisture, oil, and foreign matter contained in the air that has passed through the trap oil, and relates to a trap device of a vacuum pump moisture removal system.

[0012] The plurality of compartments are connected to each other through communication ports, and the communication ports formed at the upper and lower parts of the compartments are formed to intersect left and right. The air passing through the trap oil filled in the plurality of compartments including the lowermost compartment of the housing moves left and right and rises along the communication ports formed to intersect left and right, and the air transferred to the compartment located at the lowermost stage of the housing through the inflow pipe passes through the trap oil and moves to the upper part of the housing. The compartment located at the uppermost stage of the housing is connected to a vacuum pump so that the air is sucked into the vacuum pump, thereby effectively removing moisture.

[0013] As another prior art, as shown in FIG. 7b, Korean Registered Patent No. 10-1868914, "Moisture Removal System for Vacuum Pump" (hereinafter referred to as "Patent Document 2"), includes a vacuum pump for sucking air from a vacuum target to form a negative pressure inside the vacuum target, and an auxiliary vacuum pump for sucking air inside the vacuum pump. Moisture contained in the air inhaled from the vacuum target and sucked by the vacuum pump is condensed inside the vacuum pump. When the internal pressure of the vacuum pump is reduced by the auxiliary vacuum pump, the condensed water generated by condensation inside the vacuum pump is vaporized and discharged to the outside of the vacuum pump by the auxiliary vacuum pump, so that moisture contained in the air inhaled from the vacuum target and flowing into the vacuum pump can be effectively removed. It relates to a moisture removal system for a vacuum pump.

[0014] As described above, Patent Documents 1 to 2 are in the same technical field as the present invention, and there are similar and same concepts in the object of the invention of removing moisture contained in the air flowing into the device that sucks air. However, there are differences in the problems and effects to be solved by the invention and the solution means for solving them.

[0015] That is, Patent Document 1 is for providing a trap device that can effectively remove foreign substances and moisture contained in the air sucked from the vacuum target and flowing into the vacuum pump.

[0016] Note that Patent Document 2 relates to a moisture removal system for a vacuum pump that can effectively remove moisture contained in the air inhaled from the vacuum target and flowing into the vacuum pump.

[0017] Therefore, in contrast to the present invention, there are differences in technical features in the specific solution means (components) of the invention for solving the problems to be solved by the invention and exerting its effects.

[0018] Therefore, the present invention aims to define the technical features of the invention based on the problem to be solved by the invention, the object of the invention, the solution means (components) for solving this problem, and the effects achieved by solving it, which are different from the technologies of conventional devices and systems for removing moisture from compressed air including Patent Document 1 to Patent Document 2 above.

Means for Solving the Problems

[0022] The compressed air gas-liquid separation unit applied to the multi-stage turbo compressor system according to the present invention for achieving the above object is, in the compressed air gas-liquid separation unit applied to the multi-stage turbo compressor system, the compressed air gas-liquid separation unit includes a cylindrical compressed air gas-liquid separation chamber housing module into which compressed air compressed by a turbo air compression unit flows and from which condensed water is separated; a compressed air inlet module formed to penetrate through one side of the upper part of the compressed air gas-liquid separation chamber housing module and intentionally separated from the central axis of the compressed air gas-liquid separation chamber housing module so that the compressed air discharged from the turbo air compression unit flows into and swirls within the compressed air gas-liquid separation chamber housing module; a compressed air moisture removal flow guide vane module that is rotated by the compressed air flowing into the compressed air inlet module, aims to achieve active swirling of the compressed air flowing into the interior of the compressed air gas-liquid separation chamber housing module, guides the compressed air to flow into the compressed air moisture removal filtering housing module, induces friction with the compressed air, and removes condensed water from the compressed air; a compressed air moisture removal filtering housing module that is located on the same central axis inside the compressed air gas-liquid separation chamber housing module, is formed in a specific shape to remove condensed water from the compressed air flowing into the compressed air gas-liquid separation chamber housing module, and allows the compressed air from which the condensed water has been removed to be discharged to the outside; and a condensed water discharge mesh net module that allows the moisture contained in the condensed water removed from the compressed air and the floating condensed water droplets inside the compressed air gas-liquid separation chamber housing module to be discharged to the outside.

In this way, the compressed air flowing into the air and moisture separation chamber housing module through the inlet module of the compressed air is such that condensed water is primarily removed by friction with the upper end inside the air and moisture separation chamber housing module of the compressed air, condensed water is secondarily removed by friction with the moisture removal flow guide vane module of the compressed air, condensed water is tertiarily removed by friction between the inner wall of the air and moisture separation chamber housing module of the compressed air and the outer wall of the moisture removal filtering housing module of the compressed air, and condensed water is quaternarily removed by friction with the inner wall at the lower end of the moisture removal filtering housing module of the compressed air, removing moisture from the compressed air compressed by the turbo air compression unit and ensuring optimal compressed air. This is the characteristic feature.

[0024] On the other hand, prior to this, this specification states that the terms and words used in the claims for patent registration should not be interpreted in a normal or dictionary-limited sense. The inventor should, based on the principle that he can appropriately define the concept of the terms in order to explain his own invention in the best way, interpret them in a meaning and concept that conforms to the technical idea of the present invention.

[0025] Therefore, it should be understood that the embodiments described in this specification and the configurations illustrated in the drawings are only the most desirable embodiments of the present invention and do not represent all of the technical ideas of the present invention. There are various equivalents and variations that can replace them at the time of this application.

[0033] Hereinafter, the function, configuration, and operation of the compressed air steam separator 700 applied to the multi-stage turbo compressor system of the present invention will be described in detail with reference to the accompanying drawings.

[0034] FIG. 1 shows a configuration diagram of a compressed air water-steam separator applied to a multi-stage turbo compressor system according to the present invention, FIG. 2 shows a piping and instrumentation diagram (P&ID) of a multi-stage turbo compressor system to which the compressed air water-steam separator applied to a multi-stage turbo compressor system according to the present invention is applied, FIG. 3 shows a schematic diagram of the compressed air water-steam separator applied to a multi-stage turbo compressor system according to the present invention, FIG. 4 shows a first reference diagram of the compressed air water-steam separator applied to a multi-stage turbo compressor system according to the present invention, FIG. 5 shows a second reference diagram of the compressed air water-steam separator applied to a multi-stage turbo compressor system according to the present invention, and FIG. 6 shows a third reference diagram of the compressed air water-steam separator applied to a multi-stage turbo compressor system according to the present invention.

[0035] As shown in FIGS. 1 to 6, an air-water separation unit 700 for removing moisture (condensed water) from compressed air compressed through a turbo air compression unit 300 according to the present invention includes: a cylindrical air-water separation chamber housing module 710 into which the compressed air compressed by the turbo air compression unit 300 flows and in which condensed water is separated from the compressed air; an air inlet module 720 of compressed air that is formed to penetrate through one upper side of the air-water separation chamber housing module 710 of the compressed air and is intentionally separated from the central axis of the air-water separation chamber housing module 710 of the compressed air so that the compressed air discharged from the turbo air compression unit 300 flows into and swirls within the air-water separation chamber housing module 710 of the compressed air; a moisture removal flow guide vane module 730 of compressed air that is rotated by the compressed air flowing into the air inlet module 720 of the compressed air, promotes active swirling of the compressed air flowing into the air-water separation chamber housing module 710 of the compressed air, guides the compressed air to flow into a moisture removal filtering housing module 740 of the compressed air, induces friction with the compressed air, and removes condensed water from the compressed air; a moisture removal filtering housing module 740 of compressed air that is located on the same central axis inside the air-water separation chamber housing module 710 of the compressed air, is formed in a specific shape, removes condensed water from the compressed air flowing into the air-water separation chamber housing module 710 of the compressed air, and allows the compressed air from which the condensed water has been removed to be discharged to the outside; and a condensed water discharge mesh net module 750 that allows the moisture contained in the condensed water removed from the compressed air and the floating condensed water droplets inside the air-water separation chamber housing module 710 of the compressed air to be discharged to the outside.

[0036] The compressed air flowing in through the compressed air inlet module 720 passes through the compressed air inlet module 720 and the upper end inside the compressed air air-water separation chamber housing module 710, and then flows into the compressed air moisture removal flow guide vane module 730 and the compressed air moisture removal filtering housing module 740, generating a discharge path R for the moisture-removed compressed air so that the compressed air with condensed water removed is discharged to the outside.

[0037] Therefore, the compressed air flowing into the compressed air air-water separation chamber housing module 710 through the compressed air inlet module 720 is such that condensed water is primarily removed by friction with the upper end inside the compressed air air-water separation chamber housing module 710, secondarily removed by friction with the compressed air moisture removal flow guide vane module 730, tertiarily removed by friction between the inner wall of the compressed air air-water separation chamber housing module 710 and the outer wall of the compressed air moisture removal filtering housing module 740, and quaternarily removed by friction with the inner wall of the lower end of the compressed air moisture removal filtering housing module 740, removing moisture from the compressed air compressed by the turbo air compression unit 300 and ensuring optimal compressed air.

[0038] That is, the condensed water contained in the flow of compressed air flowing into the compressed air air-water separation unit 700 is frictionally engaged with the inner wall surface of the compressed air air-water separation unit 700 by centrifugal force, falls along the inner wall surface, accumulates at its lower end, and is discharged to the outside.

[0039] That is, the compressed air flowing while swirling inside the compressed air air-water separation unit 700 moves along a specific path while moisture is removed, and the condensed water droplets floating during the flow until the compressed air is discharged to the outside fall to the lower end of the compressed air air-water separation unit 700 by inertia, guiding only the compressed air with moisture removed to be discharged to the outside.

[0040] More specifically, the compressed air water separation chamber housing module 710 guides the compressed air flowing in through the compressed air inlet module 720 to flow into the compressed air condensate removal swirling space body element 712, and is composed of: a compressed air condensate removal swirling space upper end element 711 having a specific inclination that allows condensate to be removed from the compressed air by friction with the compressed air flowing in through the compressed air inlet module 720; a compressed air condensate removal swirling space body element 712 that allows the compressed air flowing downward to swirl and remove condensate from the compressed air by friction with the compressed air condensate removal swirling space upper end element 711; and a compressed air condensate removal swirling space lower end element 713 having a condensate discharge hole 713a formed therein that allows the condensate removed from the compressed air to drop and be discharged to the outside while swirling in the compressed air condensate removal swirling space body element 712.

[0041] Therefore, as described above, the compressed air flowing in from the compressed air inlet module 720 is caused to swirl along a specific path, and condensed water is removed.

[0042] The compressed air inlet module 720 is formed to penetrate so that the compressed air discharged from the turbo air compressor 300 can flow into the compressed air water separation chamber housing module 710, and is intentionally spaced apart from the central axis of the compressed air water separation chamber housing module 710 so that the compressed air flowing into the compressed air water separation chamber housing module 710 can swirl and flow along a specific path.

[0043] The moisture removal flow guide vane module 730 of the compressed air is formed below the position of the compressed air inlet module 720 formed on one side of the upper end of the gas-liquid separation chamber housing module 710 of the compressed air, and is located inside the removal swirling space body element 712 of the compressed air condensed water. It is rotated by the compressed air flowing in from the compressed air inlet module 720, aims to create a swirling flow of the compressed air, and enables the condensed water to be removed from the compressed air through secondary friction with the compressed air.

[0044] The moisture removal filtering housing module 740 of the compressed air is formed in a funnel shape. The compressed air swirling and flowing inside the removal swirling space body element 712 of the compressed air condensed water is finally removed of the condensed water from the compressed air before flowing to the discharge port element 742 of the moisture-removed compressed air and being discharged to the outside. It includes a moisture removal filtering element 741 of the compressed air with a trapezoidal cross-section; and a discharge port element 742 of the moisture-removed compressed air that extends a certain length from the upper end of the moisture removal filtering element 741 of the compressed air and discharges the compressed air finally removed of the condensed water through the moisture removal filtering element 741 of the compressed air to the outside.

[0045] Therefore, the condensed water is removed from the compressed air flowing into the compressed air inlet module 720 so that optimal compressed air is discharged to the outside.

[0046] At this time, the reason for forming it in a funnel shape is to increase the diameter of the moisture removal filtering element 741 of the compressed air, increase the flow rate of the compressed air swirling along the outer peripheral surface of the moisture removal filtering element 741 of the compressed air, reduce the flow rate of the compressed air flowing into the inside of the moisture removal filtering element 741 of the compressed air, cause the suspended droplets to fall due to inertia, and be discharged to the outside through the condensed water discharge mesh module 750.

[0047] That is, it is for more effectively removing the moisture in the compressed air.

[0048] The condensed water discharge mesh module 750 is formed and positioned on one side between the lower part of the compressed air condensed water removal swirling space body element 712 and the lower end element 713 of the compressed air condensed water removal swirling space. It is formed with through holes in a specific pattern at a certain interval of particle sizes, so that the condensed water removed from the compressed air drips off and is discharged to the outside through the condensed water discharge hole 713a.

[0049] On the other hand, in the multi-stage turbo compressor system 1 equipped with a compressed air air-water separation unit according to the present invention, there are: an external air suction unit 100 into which external air flows in and is inhaled; an external air filtering unit 200 that filters the external air flowing in and inhaled through the external air suction unit 100; a turbo air compression unit 300 into which the external air filtered by the external air filtering unit 200 flows in and is inhaled to generate compressed air; a cooling unit 400 of the turbo air compression unit that cools the turbo air compression unit 300; a power supply unit 500 of the turbo air compression unit that operates the turbo air compression unit 300; a compressed air cooling intercooler unit 600 that cools the compressed air generated through the turbo air compression unit 300; a compressed air air-water separation unit 700 that separates condensed water from the compressed air cooled through the compressed air cooling intercooler unit 600; and a compressed air discharge unit 800 through which the compressed air from which the condensed water has been removed through the compressed air air-water separation unit 700 is discharged.

[0050] Therefore, it is characterized in that the external air inhaled into the external air suction unit 100 is discharged as optimal compressed air from which moisture has been removed through the compressed air discharge unit 800 via the external air filtering unit 200, the turbo air compression unit 300, the compressed air cooling intercooler unit 600, and the compressed air air-water separation unit 700.

[0051] That is, as described above, when compressing external air through the turbo air compressor section 300 and discharging compressed air, before the compressed air compressed through the turbo air compressor section 300 is discharged to the outside, by passing it through the moisture separation section 700 of the compressed air and discharging it, moisture (condensed water) contained in the compressed air is removed, so that optimal compressed air with the moisture (condensed water) removed can be obtained.

[0052] At this time, the compressed air discharge section 800 includes: an external supply and discharge module 810 of compressed air that discharges compressed air to a place where compressed air is required outside the multi-stage turbo compressor system 1 including the moisture separation section of the compressed air; and an internal supply and discharge module 820 of compressed air that discharges compressed air into the multi-stage turbo compressor system 1 including the moisture separation section of the compressed air according to the discharge pressure of the compressed air discharged to the external supply and discharge module 810 of the compressed air.

[0053] The internal supply and discharge module 820 of the compressed air includes: a blow-off valve element 821 that prevents the backflow of the compressed air discharged to the external supply and discharge module 810 of the compressed air and induces a smooth flow of the compressed air; a compressed air volume adjustment valve element 822 that adjusts the amount of compressed air flowing through the opening of the blow-off valve element 821; and a compressed air discharge noise prevention muffler element 823 that reduces the noise generated when the compressed air is discharged.

[0054] Therefore, by discharging and supplying compressed air inside and outside with reference to the multi-stage turbo compressor system 1 including the moisture separation section of the compressed air, a smooth flow of compressed air is achieved.

[0055] At this time, an additional moisture separation section 700 of the compressed air is formed in the internal supply and discharge module 820 of the compressed air.

[0056] Therefore, the moisture in the compressed air is removed again, and the compressed air with the moisture removed is discharged into the multi-stage turbo compressor system 1 including the moisture separation section of the compressed air.

[0057] As described above, the present invention is not limited to the described embodiments, and it is obvious to those with ordinary knowledge in this technical field that various modifications and variations can be made without departing from the spirit and scope of the present invention.

[0058] Therefore, without departing from the technical idea and main features, it can be implemented in various other forms. Thus, the embodiments of the present invention are merely illustrative in every respect and should not be construed in a limiting sense, and can be implemented with various modifications.

Industrial Applicability

[0059] The present invention relates to a moisture separation unit for compressed air applied to a multistage turbo compressor system. By being able to provide optimal compressed air with moisture removed at industrial sites where compressed air is required, in the manufacturing and sales operations of manufacturing this, it can contribute to enhancing not only energy efficiency but also the durability and lifespan of the system where compressed air is used, extending the lifespan, and promoting various industrial fields that utilize compressed air.
