Description

Technical Field

[0001] The present invention relates to a fluid recovery system and a fluid recovery method using the same, and more particularly, to a fluid recovery system capable of effectively separating and recovering only a specific fluid from a mixture containing a plurality of fluids, and a fluid recovery method using the same.

Background Art

[0002] A gas insulated switchgear (GIS) is a safety device installed in high-voltage power systems such as power plants or substations. The gas insulated switchgear performs switching of load current under normal operating conditions. In addition, the gas insulated switchgear is provided to protect the power system by switching lines even in abnormal situations such as occurrence of fault current or short-circuit current.

[0003] The gas insulated switchgear is provided with insulating gas. The insulating gas is provided in the gas insulated switchgear, and performs an insulating function, thereby improving the operational reliability of the gas insulated switchgear.

[0004] Traditional gas insulated switchgears are provided with sulfur hexafluoride (SF6) as an insulating gas. Sulfur hexafluoride can be produced at low cost, has excellent insulating properties, high arc extinguishing capability for generated arcs, and fast insulation recovery speed, so it is widely used as an insulating gas.

[0005] Meanwhile, sulfur hexafluoride corresponds to a greenhouse gas that induces global warming. Recently, with increasing interest in environmental protection and stricter regulations, agreements for greenhouse gas reduction have been formed mainly in developed countries, and research for developing insulating gases to replace sulfur hexafluoride is underway.

[0006] For example, NOVEC 1230 (C6F developed by 3M Company 12 O) and the like have been developed and are being utilized to replace sulfur hexafluoride. However, in the case of insulating gases developed up to now, excessive costs are required to ensure insulating performance equivalent to that of sulfur hexafluoride.

[0007] Furthermore, insulating gas also has the properties of a consumer good. That is, as gas-insulated switchgear continues to be used, the insulating gas must be periodically replaced and refilled. Therefore, the continuous supply of expensive insulating gas to gas-insulated switchgear represents a significant burden for both the operators of the power grid and the consumers who receive electricity.

[0008] Following this, a technology for recovering and reusing previously used insulating gases was introduced.

[0009] Korean Patent Publication No. 10-1086311 discloses a gas filter device for a sulfur hexafluoride gas-insulated switchgear. Specifically, it discloses a gas filter device with a structure that allows dust and other contaminants contained in the recovered sulfur hexafluoride gas to be removed and then reintroduced.

[0010] Incidentally, the gas filter device for sulfur hexafluoride gas-insulated switchgear disclosed in the aforementioned prior art document still assumes the use of sulfur hexafluoride as the insulating gas. In other words, the aforementioned prior art document does not present any proposals for materials to be used as an insulating gas in place of sulfur hexafluoride.

[0011] International Publication No. 2015-102229 discloses a method for treating sulfur hexafluoride using radiation, a by-product recovery method, and a treatment apparatus. Specifically, it discloses a treatment method and apparatus for irradiating a mixed gas of sulfur hexafluoride and hydrogen with radiation to decompose the sulfur hexafluoride and hydrogen into hydrogen fluoride and sulfur, and then recover the resulting product.

[0012] Incidentally, the processing method and processing apparatus disclosed in the aforementioned prior art document only disclose a method for removing sulfur hexafluoride, assuming that sulfur hexafluoride is used as the insulating gas. In other words, the aforementioned prior art document does not present a method for recovering insulating gas composed of substances other than sulfur hexafluoride.

[Effects of the Invention]

[0039] With the above configuration, the fluid recovery system and fluid recovery method using the embodiment of the present invention can efficiently separate the fluid to be recovered from the mixed fluid.

[0040] The fluid recovery system is equipped with an inlet communication section that communicates with the outside. The inlet communication section communicates with the fluid separation section via an inlet flow path section. The incoming mixed fluid can be transmitted to the fluid separation section.

[0041] The fluid separation section includes a filter member. In one embodiment, the filter member can separate a mixed fluid into at least two distinct fluids by providing a membrane. The fluid to be recovered can flow along the longitudinal direction of the filter member and be discharged and recovered. The remaining fluid, excluding the fluid to be recovered, can be discharged by passing through the membrane in another direction from the filter member, for example, radially.

[0042] Furthermore, with the above configuration, the fluid recovery system and fluid recovery method using the embodiment of the present invention can allow the fluid to be recovered to undergo separation processes multiple times.

[0043] In one embodiment, a plurality of filter members may be provided. The plurality of filter members are connected and in communication with each other, and the mixed fluid transmitted to the fluid separation section can pass through at least one filter member to undergo the separation process.

[0044] Multiple filter components are connected to and communicate with multiple branched channels. Multiple branched valves are provided on each of the branched channels, and these valves control the opening or closing of the branched channels independently of each other.

[0045] In this case, multiple branch valves may be controlled to correspond to each other, forming different flow paths through which the mixed fluid can flow. In any case, the mixed fluid undergoes a separation process by passing through the filter member at least once.

[0046] Furthermore, with the above configuration, the fluid recovery system and fluid recovery method using the embodiment of the present invention can improve the separation efficiency of the fluid to be recovered.

[0047] In one embodiment, a heating member is connected to the filter member. The heating member is configured to heat the filter member and the mixed fluid flowing inside it. This keeps the mixed fluid in the gas phase, improving separation efficiency.

[0048] Furthermore, with the above configuration, the fluid recovery system and fluid recovery method using the embodiment of the present invention can efficiently capture and recover the fluid to be recovered.

[0049] The fluid to be recovered, having passed through the filter member, flows into the capture member. The capture member is configured to undergo a phase change and capture the fluid to be recovered. As a result, the fluid to be recovered undergoes a phase change into a liquid phase, which is relatively easier to capture and recover, and is then captured.

[0050] In one embodiment, a cooling member is connected to the capture member. The cooling member is configured to cool the capture member and the fluid to be recovered that flows into its interior. As a result, the fluid to be recovered undergoes a phase change to a liquid phase and is maintained there, improving the capture and recovery efficiency.

[0051] Furthermore, with the above configuration, the fluid recovery system and fluid recovery method using the embodiment of the present invention allow the remaining fluid to be recovered to undergo a separation process again.

[0052] In one embodiment, a fluid recovery unit may be provided. The fluid recovery unit is connected to and communicates with the inlet communication unit and the outlet communication unit, respectively. Residual fluid that has not yet undergone phase change or been captured by the capturing member is transmitted again to the fluid separation unit via the fluid recovery unit and can undergo the separation process again.

[0053] This allows the separation process to be repeated even if the fluid to be recovered is not completely separated from the mixed fluid, thereby improving the separation and recovery efficiency of the fluid to be recovered.

[0054] The effects of the present invention are not limited to those described above, but should be understood to include all effects that can be inferred from the detailed description of the present invention or the configuration of the invention as described in the claims.

[0058] Therefore, the embodiments described herein and the configurations shown in the drawings constitute a preferred embodiment of the present invention and do not represent the entire technical idea of ​​the present invention; thus, there may be various equivalents and modifications that can be substituted for these configurations at the time of filing of the present invention.

[0059] 1. Definition of Terms In the following description, the term "communication" means that one or more members are connected to each other in a way that allows for fluid communication. In one embodiment, communication can be achieved by members such as conduits, pipes, or piping.

[0060] In the following description, the term "energized" means that one or more components are connected to each other in a manner that allows them to transmit electric current or electrical signals. In one embodiment, energization can be performed in a wired manner, such as by a conductive component, or in a wireless manner, such as Bluetooth, Wi-Fi, or RFID.

[0061] In the following description, the term “fluid” refers to any state of matter whose shape can be altered by external pressure or temperature. In one embodiment, the fluid may be provided in the form of a liquid or a gas.

[0062] In the following description, the term "mixed fluid" refers to any fluid supplied to the fluid recovery systems 10 and 20 and subject to a separation process. In one embodiment, the mixed fluid may consist of fluid discharged from an external device, such as a gas-insulated switchgear.

[0065] 2. Description of the configuration of the fluid recovery systems 10 and 20 according to embodiments of the present invention The fluid recovery systems 10 and 20 according to embodiments of the present invention can receive a mixed fluid from an external device and separate it into multiple fluids. The separated multiple fluids can be discharged to the outside via different paths.

[0066] Therefore, one of the fluids mixed into the mixed fluid can be separated from the other fluids and supplied again to an external device. This increases the recovery efficiency of the one of the fluids mixed into the mixed fluid and reduces the amount of the one of the fluids that needs to be newly supplied to the external device.

[0067] This reduces the financial costs required to operate external equipment. Furthermore, as the recovery efficiency of any one fluid improves, the amount of any new fluid needed decreases, thus preventing environmental pollution.

The inflow channel section 210 extends from between the inflow communication section 110 and the filter member 310, and each end in the direction of this extension is connected to and communicates with the inflow communication section 110 and the filter member 310, respectively.

[0095] The mixed fluid that flows in through the inlet communication section 110 flows inside the inlet channel section 210. The mixed fluid flows along the inlet channel section 210 and can be guided to the filter member 310.

[0096] A utility unit 500 may be provided on the inflow channel 210. The utility unit 500 processes the mixed fluid flowing inside the inflow channel 210 and can sense information regarding the flow of the mixed fluid.

[0097] In the embodiment shown in Figure 2, a particle filter member 510, a pressure regulating member 520, a sensor member 540, and a valve member 550 are provided on the inflow channel section 210.

[0098] In the illustrated embodiment, the inflow channel section 210 is connected to and communicates with the first filter member 311, which is located on the upstream side of the filter members 310. The inflow channel section 210 can be connected to and communicate with any one of the multiple filter members 310.

[0099] The outflow channel section 220 connects the outflow communication section 120 of the communication section 100 with the capture member 320 of the fluid separation section 300. The outflow channel section 220 extends from between the outflow communication section 120 and the capture member 320, and each end in the direction of this extension is connected to and communicates with the outflow communication section 120 and the capture member 320, respectively.

[0100] Inside the outflow channel section 220, one of the fluids remaining after passing through the filter member 310 and the capture member 320 of the fluid separation section 300 flows. This one fluid flows along the outflow channel section 220 and is discharged to the outside via the outflow communication section 120 for recovery.

[0101] A utility unit 500 may be provided on the outflow channel 220. The utility unit 500 can process any one of the fluids flowing inside the outflow channel 220 (i.e., the one that remains without separation) and can sense information regarding the flow of any one of the fluids.

[0102] In the embodiment shown in Figure 2, a flow velocity adjustment member 530 and a sensor member 540 are provided on the outflow channel section 220.

[0103] The exhaust passage section 230 connects the exhaust communication section 130 of the communication section 100 with the filter member 310 of the fluid separation section 300. The exhaust passage section 230 extends from between the exhaust communication section 130 and the filter member 310, and each end in the direction of this extension is connected to and communicates with the exhaust communication section 130 and the filter member 310, respectively.

[0104] Inside the exhaust passage section 230, the mixed fluid that flows in passes through the filter member 310 and separates it from other fluids. These other fluids flow along the exhaust passage section 230 and can be discharged to the outside through the exhaust communication section 130. As mentioned above, in one embodiment, the other fluid may be oxygen or hydrogen, etc.

[0105] Multiple exhaust passage sections 230 may be provided. Multiple exhaust passage sections 230 may be connected to multiple exhaust communication sections 130 and multiple filter members 310, respectively, and configured to communicate with each other.

[0106] In the illustrated embodiment, the exhaust passage section 230 is provided in three parts, including a first exhaust passage section 231, a second exhaust passage section 232, and a third exhaust passage section 233.

[0107] The first exhaust passage section 231 is connected to and communicates with the first exhaust communication section 131 and the first filter member 311, respectively. The second exhaust passage section 232 is connected to and communicates with the second exhaust communication section 132 and the second filter member 312, respectively. The third exhaust passage section 233 is connected to and communicates with the third exhaust communication section 133 and the third filter member 313, respectively.

[0108] The capture channel section 240 connects the capture communication section 140 of the communication section 100 with the capture member 320 of the fluid separation section 300. The capture channel section 240 extends from between the capture communication section 140 and the capture member 320, and each end in the direction of this extension is connected to and communicates with the capture communication section 140 and the capture member 320, respectively.

[0109] The capture channel section 240 branches off at the outflow channel section 220 via the capture member 320. A tank member 330 is provided on the capture channel section 240 to contain one of the fluids that has undergone a phase change after passing through the capture member 320. The capture channel section 240 communicates with the tank member 330.

[0110] A transfer member 340 is provided on the capture channel section 240 to provide a transfer force to one of the fluids captured by the capture member 320 or one of the fluids contained in the tank member 330. The capture channel section 240 communicates with the transfer member 340.

[0111] Inside the capture channel section 240, one of the fluids that has been captured and undergone a phase change by the capture member 320 flows. The fluid can be discharged to the outside and recovered by the transfer force provided by the transfer member 340, flowing from the capture channel section 240 to the tank member 330, and from the tank member 330 towards the capture communication section 140.

[0112] The flow channel heat dissipation member 250 is located on the outflow channel section 220 and is configured to cool any one of the fluids flowing inside the outflow channel section 220. As the flow channel heat dissipation member 250 cools any one of the fluids, the phase change process in the capture member 320 can be carried out efficiently.

[0113] In the embodiment shown in Figure 2, the flow path heat dissipation member 250 is located downstream of the filter member 310 and upstream of the capture member 320 of the fluid separation unit 300. That is, the flow path heat dissipation member 250 is configured to cool one of the fluids that has passed through the filter member 310 before it flows into the capture member 320.

[0114] The flow path heat dissipation member 250 is provided on the outflow flow path section 220 and may be provided in any form that can cool any one of the fluids flowing inside it. In one embodiment, the flow path heat dissipation member 250 may be provided in the form of a chiller or a thermoelectric module (Peltier element).

[0115] The fluid separation unit 300 substantially performs the role of separating the mixed fluid supplied from the outside. The fluid separation unit 300 is connected to and communicates with the communication unit 100 via the flow path unit 200, and can receive the mixed fluid from the outside. The received mixed fluid passes through the fluid separation unit 300, is separated into one fluid and the other, and can then be discharged and recovered to the outside via the flow path unit 200 and the communication unit 100.

[0116] The fluid separation section 300 is connected to and communicates with the flow path section 200. Specifically, the fluid separation section 300 is connected to and communicates with the inflow flow path section 210, and the mixed fluid that flows in through the inflow communication section 110 can flow into the filter member 310 of the fluid separation section 300.

[0117] Furthermore, the fluid separation section 300 is connected to and communicates with the outlet channel section 220, allowing any one fluid that has not yet been separated from the mixed fluid (i.e., any one remaining fluid) to be discharged to the outside and recovered via the outlet communication section 120.

[0118] Furthermore, the fluid separation unit 300 is connected to and communicates with the exhaust flow path unit 230, allowing other fluids separated from the mixed fluid to be discharged to the outside and recovered via the exhaust communication unit 130.

[0119] Furthermore, the fluid separation unit 300 is connected to and communicates with the capture flow channel unit 240, allowing any one of the fluids separated from the mixed fluid, undergoing phase change, and being captured to be discharged or recovered to the outside via the capture communication unit 140.

[0120] In addition, a flow path heat dissipation member 250 may be provided on the flow path that connects each component of the fluid separation section 300 (i.e., the outflow flow path section 220 in the embodiment shown in Figure 2). The flow path heat dissipation member 250 is configured to cool any one of the fluids that has passed through a part of the fluid separation section 300. This makes it possible to more effectively bring about a phase change in any one of the fluids.

[0121] In the illustrated embodiment, the fluid separation unit 300 includes a filter member 310, a capture member 320, a tank member 330, a transfer member 340, a branching channel 350, and a branching valve 360.

[0122] The filter member 310 separates the mixed fluid, which flows in through the inlet communication section 110 and along the inlet flow path section 210, into one fluid and the other fluid. The filter member 310 is connected to and communicates with the inlet flow path section 210.

[0123] One of the fluids separated by the filter member 310 undergoes a phase change via the outflow channel 220 and the capture member 320 before flowing into the tank member 330. The filter member 310 is connected to and communicates with the outflow channel 220.

[0124] Other fluids separated by the filter member 310 are discharged to the outside via the exhaust passage section 230 and the exhaust communication section 130. The filter member 310 is connected to and communicates with the exhaust passage section 230.

[0125] The filter member 310 may be configured in any form capable of separating multiple fluids having different physical and chemical properties. In one embodiment, the filter member 310 may be provided in the form of a membrane filter containing multiple hollow fibers.

[0126] In the above embodiment, one of the mixed fluids flowing into the filter member 310 can flow in the longitudinal direction without passing through the membrane and be discharged from the filter member 310. The other fluids can pass through the membrane and flow radially and be discharged.

[0127] In one embodiment, hollow fibers can be manufactured using super engineering plastics such as polysulfone and polyimide as materials. In this case, the hollow fibers can be manufactured through a spinning process.

[0128] In the above embodiment, the membrane constituting the filter member 310 can be designed to have permeability for various fluids as shown in Table 1 below.

[0129] [Table 1]

[0130] Furthermore, the membrane constituting the filter element 310 can be designed to have the selectivity shown in Table 2 below for various fluids.

[0131] [Table 2]

[0132] Furthermore, in the above embodiment, the flow rate of the fluid that the fluid recovery system 10 can process can be determined by the area of ​​the membrane, that is, the area of ​​the membrane including the hollow fibers. In one embodiment, the flow rate of the fluid that the fluid recovery system 10 can process may be proportional to the area of ​​the membrane.

[0133] For example, if the membrane is 4.0~5.0m 2 When provided to have the area of ​​the above, the mixed fluid can be supplied to the fluid recovery system 10 at a flow rate of 10 L per minute (10 L / min).

[0134] Multiple filter members 310 may be provided. Multiple filter members 310 are connected and communicate with each other, and the mixed fluid flowing in through the inflow channel 210 passes through the multiple filter members 310 in sequence. As a result, the mixed fluid is separated into one fluid and the other fluid multiple times. Consequently, the separation efficiency of the mixed fluid can be improved.

[0135] In the embodiment shown in Figure 2, the filter member 310 is provided in three parts, including a first filter member 311, a second filter member 312, and a third filter member 313. The number of filter members 310 may be any number that can effectively separate the mixed fluid.

[0136] In an embodiment in which multiple filter members 310 are provided, a branch channel 350 and a branch valve 360 ​​provided on the branch channel 350 for controlling the opening and closing of the branch channel 350 are provided between each filter member 310.

[0137] In the illustrated embodiment, the first filter member 311 is connected to and communicates with the first branch channel 351 and the sixth branch channel 356, respectively. The second filter member 312 is connected to the first branch channel 351 and the third branch channel 353, respectively. The third filter member 313 is connected to the fourth branch channel 354 and the seventh branch channel 357, respectively.

[0138] As a result, the mixed fluid that flows through the inflow channel 210 and into the fluid separation section 300 selectively passes through one or more of the multiple filter members 310, separating into one fluid and the other fluids. A detailed explanation of this will be given later. The first filter member 311 is connected to and communicates with the inflow channel 210. The mixed fluid that flows in through the inflow communication section 110 can flow through the inflow channel 210 to the first filter member 311. In other words, the fluid recovery system 10 according to the embodiment of the present invention may be configured such that the incoming mixed fluid always passes through the first filter member 311 before being discharged.

[0139] The first filter member 311 is connected to and communicates with the first exhaust flow path section 231. Any other fluid separated from the mixed fluid after passing through the first filter member 311 can be discharged to the outside via the first exhaust flow path section 231 and the first exhaust communication section 131.

[0140] As described above, in one embodiment, the other fluid can flow radially through the first filter member 311. Therefore, it is understood that the first filter member 311 can communicate with the first exhaust flow path section 231 in its radial direction.

[0141] The first filter member 311 is connected to and communicates with the first branched flow path 351. Any one of the fluids separated from the mixed fluid after passing through the first filter member 311 can flow to the second filter member 312 or the sixth branched flow path 356 via the first branched flow path 351.

[0142] As described above, in one embodiment, either one of the fluids, i.e., the remaining fluid after the other fluids have been separated from the mixed fluid, can flow in the longitudinal direction of the first filter member 311. Therefore, it is understood that the first filter member 311 can communicate with the first branched flow path 351 in its longitudinal direction.

[0143] This allows any one of the fluids that has passed through the first filter member 311 to selectively flow toward either the second filter member 312 or the sixth branch channel 356. This is achieved by the first branch valve 361, which will be described later.

[0144] The second filter member 312 is connected to and communicates with the first filter member 311 and the third filter member 313. Any one of the fluids that has passed through the first filter member 311 can flow into the second filter member 312. Any one of the fluids that has flowed in can pass through the second filter member 312, undergo another separation process, and then be discharged.

[0145] The second filter member 312 is connected to and communicates with the first branched flow path 351. Any one of the fluids that has passed through the first filter member 311 flows into the second filter member 312 via the first branched flow path 351.

[0146] The second filter member 312 is connected to and communicates with the second exhaust passage section 232. Any fluid that has been further separated from either fluid by passing through the second filter member 312 can be discharged to the outside via the second exhaust communication section 132 through the second exhaust passage section 232.

[0147] As described above, in one embodiment, the other fluid can flow radially through the second filter member 312. Therefore, it is understood that the second filter member 312 can communicate with the second exhaust flow path section 232 in its radial direction.

[0148] The second filter member 312 is connected to and communicates with the third branch channel 353. Any one of the fluids that has passed through the second filter member 312 and undergone an additional separation process can flow to the third filter member 313 or the fifth branch channel 355 via the third branch channel 353.

[0149] As described above, in one embodiment, either one of the fluids can flow in the longitudinal direction of the second filter member 312. Therefore, it is understood that the second filter member 312 can communicate with the third branched flow path 353 in its longitudinal direction.

[0150] This allows any one of the fluids that has passed through the second filter member 312 to selectively flow toward either the third filter member 313 or the sixth branch channel 356. This is achieved by the third branch valve 363 and the fourth branch valve 364, which will be described later.

[0151] The third filter member 313 is connected to and communicates with the second filter member 312 and the outflow channel section 220. Any one of the fluids that has passed through the first filter member 311 or the second filter member 312 can flow into the third filter member 313. Any one of the fluids that has flowed in can pass through the third filter member 313, undergo another separation process, and then be discharged.

[0152] The third filter member 313 is connected to and communicates with the fourth branch channel 354. Any one of the fluids that has passed through the second filter member 312 can flow into the third filter member 313 via the fourth branch channel 354.

[0153] The third filter member 313 is connected to and communicates with the third exhaust passage section 233. Any fluid that has been further separated from one of the fluids by passing through the third filter member 313 can be discharged to the outside via the third exhaust communication section 133 through the third exhaust passage section 233.

[0154] As described above, in one embodiment, the other fluid can flow radially through the third filter member 313. Therefore, it is understood that the third filter member 313 can communicate with the third exhaust flow path section 233 in its radial direction.

[0155] The third filter member 313 is connected to and communicates with the seventh branch channel 357. Any one of the fluids that has passed through the third filter member 313 can flow to the outlet channel section 220 via the seventh branch channel 357.

[0156] As described above, in one embodiment, either one of the fluids can flow in the longitudinal direction of the third filter member 313. Therefore, it is understood that the third filter member 313 can communicate with the seventh branch channel 357 in its longitudinal direction.

[0157] As a result, any one of the fluids that has passed through the third filter member 313 is subjected to a phase change and captured by the capture member 320 provided on the outflow channel section 220, and can be discharged and recovered to the outside via the capture channel section 240 and the capture communication section 140.

[0158] The capture member 320 captures any one of the fluids that has passed through the filter member 310 by changing its phase. In one embodiment, the capture member 320 may be configured to capture any one of the gas phase fluids by changing its phase to the liquid phase.

[0159] This allows for a reduction in the volume of space occupied by one of the fluids compared to when one of the fluids is maintained in the gas phase. Furthermore, as one of the fluids undergoes a phase transition to the liquid phase, it can be captured more effectively.

[0160] The capture member 320 is connected to and communicates with the outflow channel section 220. Any one of the fluids separated from the mixed fluid after passing through the filter member 310 can flow into the capture member 320. For this purpose, the capture member 320 is connected to and communicates with the sixth branch channel 356 and the seventh branch channel 357, respectively, via the outflow channel section 220.

[0161] Therefore, it can be said that the capturing member 320 is in communication with the filter member 310 via the outflow channel section 220.

[0162] A flow path heat dissipation member 250 may be provided on the outflow channel section 220 that connects the capture member 320 and the filter member 310. As described above, the flow path heat dissipation member 250 can further cool any one of the fluids discharged from the filter member 310, thereby improving the phase change efficiency in the capture member 320.

[0163] The capture member 320 communicates with the outlet communication section 120. Specifically, the capture member 320 is connected to and communicates with the outlet communication section 120 via the outlet flow path section 220. Any fluid that has not yet undergone phase change or been captured by the capture member 320 can flow along the outlet flow path section 220 and be discharged and recovered through the outlet communication section 120.

[0164] The capture member 320 is connected to and communicates with the capture flow channel 240. Any one of the fluids that undergoes a phase change and is captured in the capture member 320 can flow to the tank member 330 via the capture flow channel 240.

[0165] The capture member 320 may be provided in any form that can change the phase of any one of the separated fluids and capture it. In one embodiment, the capture member 320 may be configured to adjust the pressure or temperature to change the phase of any one of the incoming fluids and capture it.

[0166] The tank member 330 receives and stores one of the fluids that has undergone a phase change and been captured by the capture member 320. The tank member 330 is connected to and communicates with the capture member 320.

[0167] The tank member 330 is connected to and communicates with the capture channel section 240. The tank member 330 is located on the middle side of the capture channel section 240 and is connected to and communicates with the capture member 320 located on the upstream side of the capture channel section 240 and the transfer member 340 located on the downstream side of the capture channel section 240.

[0168] In other words, the tank member 330 is in communication with the capture member 320 and the transfer member 340, respectively, via the capture flow channel section 240.

[0169] The tank member 330 may be provided in any form in which a space is formed inside, and which can receive and store any one of the fluids that has undergone a phase change and been captured by the capture member 320.

[0170] The tank member 330 communicates with the transfer member 340. Any one of the fluids contained in the tank member 330 can be discharged from the tank member 330 by the transfer force provided by the transfer member 340.

[0171] The transfer member 340 provides a transfer force to any one of the fluids residing inside the capture channel section 240, the capture member 320 connected to the capture channel section 240, and the tank member 330. The transfer force provided by the transfer member 340 allows any one of the fluids to be discharged and recovered to the outside via the capture communication section 140 through the capture member 320 and the tank member 330.

[0172] The transfer member 340 is coupled to and communicates with the capture flow channel 240. The transfer force provided by the transfer member 340 can be transmitted to the interior of the capture flow channel 240 and to any configuration coupled to the capture flow channel 240.

[0173] The transfer member 340 may be provided in any form capable of generating a transfer force to cause the fluid to flow. In one embodiment, the transfer member 340 may be provided in the form of a compressor or a pump.

[0174] In the illustrated embodiment, the transfer member 340 is located downstream of the capture flow path 240. That is, the capture member 320, the tank member 330, and the transfer member 340 are arranged along the flow path of either one of the fluids. The transfer member 340 may be positioned at any location that can provide a transfer force to either of the fluids.

[0175] The branched channel 350 is connected to and communicates with each of the multiple filter members 310, thereby connecting the multiple filter members 310. The branched channel 350 is also connected to and communicates with the inflow channel section 210 and the outflow channel section 220, respectively, forming a path through which the mixed fluid flows and a path through which any one of the fluids separated from the mixed fluid flows.

[0176] In the illustrated embodiment, three filter members 310 are provided, including a first filter member 311, a second filter member 312, and a third filter member 313. As a result, multiple branching channels 350 are also provided, which can be connected to and communicate with the inflow channel section 210, the outflow channel section 220, the first filter member 311, the second filter member 312, and the third filter member 313, respectively.

[0177] In embodiments where multiple branch channels 350 are provided, the multiple branch channels 350 may be opened or closed independently of each other. This allows the multiple filter members 310 to independently control their communication with other filter members 310, inlet channel sections 210, or outlet channel sections 220. This is achieved by a branch valve 360, which will be described later.

[0178] In the illustrated embodiment, the branch channel 350 includes a first branch channel 351, a second branch channel 352, a third branch channel 353, a fourth branch channel 354, a fifth branch channel 355, a sixth branch channel 356, and a seventh branch channel 357.

[0179] The first branch channel 351 forms a single path through which any one of the fluids that has passed through the first filter member 311 flows. The first branch channel 351 is connected to and communicates with the first filter member 311 and the second filter member 312, respectively. In the illustrated embodiment, the upstream side of the first branch channel 351 is connected to and communicates with the downstream side of the first filter member 311, and the downstream side of the first branch channel 351 is connected to and communicates with the upstream side of the second filter member 312.

[0180] The first branch channel 351 communicates with the second branch channel 352. Specifically, the second branch channel 352 branches off at the first branch channel 351, forming another path through which either one of the fluids flows.

[0181] In the embodiment shown in Figure 2, the second branch channel 352 branches off from the first branch valve 361 upstream (i.e., on the right side in the illustrated embodiment) between the first filter member 311 and the second filter member 312 in the portion where the first branch channel 351 extends.

[0182] A first branch valve 361 is located on the first branch passage 351. The first branch valve 361 allows or blocks communication between the first branch passage 351 and the second filter member 312. In other words, the first branch passage 351 is provided so that it can be opened and closed by the first branch valve 361.

[0183] When the first branch valve 361 closes the first branch passage 351, any one of the fluids discharged from the first filter member 311 can flow along the second branch passage 352, which is not the second filter member 312.

[0184] Therefore, any one of the fluids that has passed through the first filter member 311 can flow through either the second filter member 312 or the second branch channel 352.

[0185] The second branch channel 352 forms another path through which any one of the fluids that has passed through the first filter member 311 flows. The second branch channel 352 communicates with the first branch channel 351, which communicates with the first filter member 311, and any one of the fluids that has passed through the first filter member 311 can flow into it.

[0186] Therefore, it can be said that the second branch channel 352 functions as a bypass channel to the first branch channel 351.

[0187] The second branch channel 352 communicates with the fifth branch channel 355. Any one fluid flowing along the second branch channel 352 can pass through the fifth branch channel 355 and the fourth branch channel 354 in sequence and flow into the third filter member 313.

[0188] The second branch channel 352 communicates with the sixth branch channel 356. Any one of the fluids flowing along the second branch channel 352 can flow into the outlet channel section 220 after passing through the sixth branch channel 356.

[0189] In the embodiment shown in Figure 2, the upstream end of the second branch channel 352 communicates with the first branch channel 351. The middle portion of the second branch channel 352 communicates with the fifth branch channel 355, and the downstream end of the second branch channel 352 communicates with the outflow channel section 220.

[0190] In this case, the upstream end of the second branch channel 352 may be located between the first filter member 311 and the first branch valve 361. The middle portion of the second branch channel 352 may be located between the second branch valve 362 and the fifth branch valve 365. The downstream end of the second branch channel 352 may be located between the third filter member 313 and the capture member 320.

[0191] Therefore, the first branch valve 361, the second branch valve 362, and the fifth branch valve 365 may be controlled respectively to allow or block communication between the second branch passage 352 and the other branch passages 351, 355, and 356.

[0192] In other words, any one fluid that flows into the second branch channel 352 can flow through either the fifth branch channel 355 or the sixth branch channel 356.

[0193] The third branch channel 353 forms a path through which any one of the fluids that has passed through the second filter member 312 flows. The third branch channel 353 is connected to and communicates with the second filter member 312. In the illustrated embodiment, the upstream side of the third branch channel 353 is connected to and communicates with the downstream side of the second filter member 312.

[0194] The third branch channel 353 is connected to and communicates with the fourth branch channel 354. Any one of the fluids that has passed through the third branch channel 353 can flow into the fourth branch channel 354. In the illustrated embodiment, the downstream end of the third branch channel 353 is connected to and communicates with the upstream end of the fourth branch channel 354.

[0195] The third branch channel 353 is connected to and communicates with the fifth branch channel 355. Any fluid that has passed through the third branch channel 353 can flow into the fifth branch channel 355. In the illustrated embodiment, the downstream end of the third branch channel 353, that is, the portion connected to and communicating with the upstream end of the fourth branch channel 354, is connected to and communicates with the upper end of the fifth branch channel 355.

[0196] Therefore, any one of the fluids that has passed through the second filter member 312 can flow through either the fourth branch channel 354 or the fifth branch channel 355 after passing through the third branch channel 353.

[0197] A third branch valve 363 is placed on the third branch passage 353. The third branch valve 363 can open or close the third branch passage 353, allowing or blocking communication between the third branch passage 353 and the second filter member 312.

[0198] The fourth branch channel 354 forms a path through which any one of the fluids that has passed through the second filter member 312 flows. The fourth branch channel 354 also forms a path through which any one of the fluids that has passed through the first filter member 311, the first branch channel 351, the second branch channel 352, and the fifth branch channel 355 in sequence flows.

[0199] In other words, one of the fluids that has passed through the first filter member 311 and then selectively passed through the second filter member 312 can flow through the fourth branch channel 354.

[0200] The fourth branch channel 354 is connected to and communicates with the third branch channel 353. Any one of the fluids that has passed through the third branch channel 353 can flow into the fourth branch channel 354. In the illustrated embodiment, the upstream end of the fourth branch channel 354 is connected to and communicates with the downstream end of the third branch channel 353.

[0201] The fourth branch channel 354 is connected to and communicates with the third filter member 313. Any one of the fluids that has passed through the fourth branch channel 354 can flow into the third filter member 313. In the illustrated embodiment, the downstream end of the fourth branch channel 354 is connected to and communicates with the upstream end of the third filter member 313.

[0202] The fourth branch channel 354 is connected to and communicates with the fifth branch channel 355. Any one of the fluids that has passed through the first filter member 311, the second branch channel 352, and the fifth branch channel 355 in sequence can flow into the fourth branch channel 354. In the illustrated embodiment, the upstream end of the fourth branch channel 354, that is, the portion connected to and communicating with the downstream end of the third branch channel 353, is connected to and communicates with the upper end of the fifth branch channel 355.

[0203] Therefore, any one of the fluids that has passed through the fourth branch channel 354 can flow through the third filter member 313 and then through the seventh branch channel 357 to the outflow channel section 220.

[0204] A fourth branch valve 364 is positioned on the fourth branch passage 354. The fourth branch valve 364 can open or close the fourth branch passage 354, thereby allowing or blocking communication between the fourth branch passage 354 and the third filter member 313.

[0205] The fifth branch channel 355 forms a path through which any one of the fluids that has passed through the first filter member 311 flows. The fifth branch channel 355 is connected to and communicates with the second branch channel 352.

[0206] In the illustrated embodiment, the lower end of the fifth branch channel 355 is connected to and communicates with the downstream end of the second branch channel 352 and the upstream end of the sixth branch channel 356, respectively. In this case, the lower end of the fifth branch channel 355 may be located between the second branch valve 362 and the fifth branch valve 365.

[0207] Furthermore, the fifth branch channel 355 forms a path through which one of the fluids that has passed through the first filter member 311 and the second filter member 312 flows. The fifth branch channel 355 is connected to and communicates with the third branch channel 353 and the fourth branch channel 354, respectively.

[0208] In the illustrated embodiment, the upper end of the fifth branch channel 355 is connected to and communicates with the downstream end of the third branch channel 353 and the upstream end of the fourth branch channel 354, respectively.

[0209] The fifth branch channel 355 each forms part of a plurality of paths through which any one of the fluids that has passed through the first filter member 311 flows.

[0210] In other words, any one of the fluids can flow through the first filter member 311, the first branch channel 351, the second filter member 312, and the third branch channel 353 in order, and then through the fifth branch channel 355 to the sixth branch channel 356. The channels are formed so that any one of the fluids passes through the first filter member 311 and the second filter member 312.

[0211] Furthermore, any one of the fluids can flow through the first filter member 311, the first branch channel 351, and the second branch channel 352 in sequence, and then through the fifth branch channel 355 to the third filter member 313. The channels are formed so that any one of the fluids passes through the first filter member 311 and the third filter member 313.

[0212] The sixth branch channel 356 forms a path through which any one of the fluids that has passed through the first filter member 311 flows. The sixth branch channel 356 is connected to and communicates with the second branch channel 352. In the illustrated embodiment, the upstream end of the sixth branch channel 356 is connected to and communicates with the downstream end of the second branch channel 352.

[0213] The sixth branch channel 356 forms a path through which any one of the fluids that has passed through the second filter member 312 flows. The sixth branch channel 356 is connected to and communicates with the fifth branch channel 355. In the illustrated embodiment, the upstream end of the sixth branch channel 356 is connected to and communicates with the lower end of the fifth branch channel 355.

[0214] Therefore, it is understood that any one of the fluids flowing in the sixth branch channel 356 is a fluid that has passed through the first filter member 311 and selectively passed through the second filter member 312.

[0215] The sixth branch channel 356 communicates with the outflow channel section 220. Any one of the fluids flowing through the sixth branch channel 356 can flow to the capture member 320 via the outflow channel section 220. In the illustrated embodiment, the downstream end of the sixth branch channel 356 is connected to and communicates with the upstream end of the outflow channel section 220 (i.e., connected to the downstream end of the seventh branch channel 357).

[0216] A fifth branch valve 365 is placed on the sixth branch passage 356. The fifth branch valve 365 can open or close the sixth branch passage 356, thereby allowing or blocking communication between the sixth branch passage 356 and the outflow passage section 220.

[0217] The seventh branch channel 357 forms a path through which any one of the fluids that has passed through the third filter member 313 flows. The seventh branch channel 357 is connected to and communicates with the third filter member 313. In the illustrated embodiment, the upstream end of the seventh branch channel 357 is connected to and communicates with the downstream end of the third filter member 313.

[0218] Any one of the fluids flowing in the seventh branch channel 357 can flow into the outlet channel section 220. The seventh branch channel 357 is connected to and communicates with the outlet channel section 220. In the illustrated embodiment, the downstream end of the seventh branch channel 357 is connected to and communicates with the upstream end of the outlet channel section 220.

[0219] A sixth branch valve 366 is positioned on the seventh branch passage 357. The sixth branch valve 366 can open or close the seventh branch passage 357, allowing or blocking communication between the third filter member 313 and the outflow passage section 220.

[0220] A detailed explanation of the various fluid pathways formed by opening or closing some of the multiple branched channels 350 will be provided later.

[0221] The branch valve 360 ​​is installed on the branch channel 350 and opens or closes the branch channel 350. As the branch valve 360 ​​operates, it allows or blocks communication between the branch channel 350 and the components connected to and communicating with the branch channel 350, thereby forming a variety of fluid channels for any one of them.

[0222] The branch valve 360 ​​may be provided in any form that can open or close the branch passage 350. The branch valve 360 ​​may be configured to be operated by physical or electrical operation. In one embodiment, the branch valve 360 ​​may be provided in the form of a solenoid valve that is operated by an electrical signal. In the above embodiment, the branch valve 360 ​​can be energized to an external control unit (not shown).

[0223] Multiple branch valves 360 may be provided. Multiple branch valves 360 are arranged on multiple branch passages 350, and each of the multiple branch passages 350 can be opened or closed.

[0224] In an embodiment where multiple branch valves 360 are provided, the multiple branch valves 360 are controlled independently of each other. In this case, some of the multiple branch valves 360 can be operated in correspondence with other parts. Through this operation, the multiple branch passages 350 can be opened or closed in correspondence with each other, thereby forming a variety of fluid passages for any one of them.

[0225] In the illustrated embodiment, the branch valve 360 ​​includes a first branch valve 361, a second branch valve 362, a third branch valve 363, a fourth branch valve 364, a fifth branch valve 365, and a sixth branch valve 366.

[0226] The first branch valve 361 is provided on the first branch passage 351 and is configured to open or close the first branch passage 351. This allows or blocks communication between the first filter member 311 and the second filter member 312.

[0227] Specifically, when the first branch valve 361 opens the first branch passage 351, the first filter member 311 and the second filter member 312 can communicate with each other through the first branch passage 351. As a result, any one of the fluids that has passed through the first filter member 311 can flow toward the second filter member 312.

[0228] When the first branch valve 361 closes the first branch passage 351, the first filter member 311 and the second filter member 312 are blocked from communicating with each other. As a result, any one of the fluids that has passed through the first filter member 311 can flow toward the second branch passage 352.

[0229] The second branch valve 362 is provided on the second branch passage 352 and is configured to open or close the second branch passage 352. This allows or blocks communication between the first filter member 311 and the fifth branch passage 355 or the sixth branch passage 356.

[0230] Specifically, when the second branch valve 362 opens the second branch passage 352, the first filter member 311 and the fifth branch passage 355 or the sixth branch passage 356 can be connected to each other by the second branch passage 352. As a result, any one of the fluids that has passed through the first filter member 311 can flow through the second branch passage 352 into the fifth branch passage 355 or the sixth branch passage 356.

[0231] When the second branch valve 362 closes the second branch passage 352, communication between the first filter member 311 and the fifth branch passage 355 or the sixth branch passage 356 is blocked. As a result, any one of the fluids that has passed through the first filter member 311 can flow toward the second filter member 312.

[0232] The third branch valve 363 is provided on the third branch passage 353 and is configured to open or close the third branch passage 353. This allows or blocks communication between the second filter member 312 and the fourth branch passage 354 or the fifth branch passage 355.

[0233] Specifically, when the third branch valve 363 opens the third branch passage 353, the second filter member 312 and the fourth branch passage 354 or the fifth branch passage 355 can communicate with each other. As a result, any one of the fluids that has passed through the second filter member 312 can flow through the third branch passage 353 into the fourth branch passage 354 or the fifth branch passage 355.

[0234] When the third branch valve 363 closes the third branch passage 353, communication between the second filter member 312 and either the fourth branch passage 354 or the fifth branch passage 355 is cut off. As a result, any one of the fluids that has passed through the second filter member 312 cannot be discharged to the outside.

[0235] Therefore, it is understood that the third branch valve 363 operates to close the third branch passage 353 if neither of the fluids flows into the second filter member 312.

[0236] The fourth branch valve 364 is provided on the fourth branch passage 354 and is configured to open or close the fourth branch passage 354. This allows or blocks communication between the third filter member 313 and the first filter member 311 or the second filter member 312.

[0237] Specifically, when the fourth branch valve 364 opens the fourth branch passage 354, the third filter member 313 and the third branch passage 353 or the fifth branch passage 355 can communicate with each other.

[0238] As a result, any one of the fluids that has passed through the first filter member 311 and flowed along the second branch channel 352 can flow to the third filter member 313 via the fifth branch channel 355. Also, any one of the fluids that has passed through the second filter member 312 can flow to the third filter member 313 via the third branch channel 353.

[0239] When the fourth branch valve 364 closes the fourth branch passage 354, communication between the fourth branch passage 354 and the third branch passage 353 or the fifth branch passage 355 is cut off. As a result, either the fluid that has passed through the first filter member 311 or the second filter member 312 will not flow into the third filter member 313, but will instead be able to flow along the sixth branch passage 356.

[0240] The fifth branch valve 365 is provided on the sixth branch passage 356 and is configured to open or close the sixth branch passage 356. This allows or blocks direct communication between the first filter member 311 or the second filter member 312 and the outflow passage section 220.

[0241] Specifically, when the fifth branch valve 365 opens the sixth branch passage 356, the second branch passage 352 and the fifth branch passage 355 communicate with the outflow passage section 220. As a result, either the fluid that has passed through the first filter member 311 or the second filter member 312 can immediately flow into the outflow passage section 220 without passing through the third filter member 313.

[0242] When the fifth branch valve 365 closes the sixth branch passage 356, communication between the second branch passage 352 and the fifth branch passage 355 and the outflow passage section 220 is cut off. As a result, either the fluid that has passed through the first filter member 311 or the second filter member 312 can pass through the third filter member 313 and then flow into the outflow passage section 220.

[0243] The sixth branch valve 366 is provided on the seventh branch passage 357 and is configured to open or close the seventh branch passage 357. This allows or blocks communication between the third filter member 313 and the outflow passage section 220.

[0244] Specifically, when the sixth branch valve 366 opens the seventh branch passage 357, the third filter member 313 and the outflow passage section 220 are connected. As a result, any one of the fluids that has passed through the third filter member 313 can flow into the outflow passage section 220.

[0245] When the sixth branch valve 366 closes the seventh branch passage 357, communication between the third filter member 313 and the outflow passage 220 is cut off. As a result, any one of the fluids that has passed through the third filter member 313 cannot be discharged to the outside.

[0246] Therefore, it is understood that the sixth branch valve 366 operates to close the seventh branch passage 357 if neither of the fluids flows into the third filter member 313.

[0247] The multiple branch valves 360 described above operate independently of each other and in a corresponding manner, forming a flow path through which any one of the fluids passes through the filter member 310.

[0248] First, we will explain the case where the incoming mixed fluid passes through all of the first to third filter members 311, 312, and 313 before flowing into the outflow channel section 220.

[0249] In this case, the first to third filter members 311, 312, and 313 must communicate with each other. For this purpose, the first branch valve 361, the third branch valve 363, and the fourth branch valve 364 are controlled to open the first branch passage 351, the third branch passage 353, and the fourth branch passage 354, respectively.

[0250] Furthermore, the third filter member 313 communicates with the outflow channel 220, and any one of the fluids that has passed through the third filter member 313 must be able to flow into the outflow channel 220. For this purpose, the sixth branch valve 366 is controlled to open the seventh branch channel 357.

[0251] In this case, the second branch valve 362 and the fifth branch valve 365 are controlled to close the second branch passage 352 and the sixth branch passage 356, respectively.

[0252] Next, we will explain the case in which the incoming mixed fluid passes only through the first filter member 311 and then flows into the outflow channel section 220.

[0253] In this case, the first filter member 311 must block communication with the second filter member 312 and the third filter member 313. To this end, the first branch valve 361, the third branch valve 363, the fourth branch valve 364, and the sixth branch valve 366 are controlled to close the first branch passage 351, the third branch passage 353, the fourth branch passage 354, and the seventh branch passage 357, respectively.

[0254] Furthermore, the second branch valve 362 and the fifth branch valve 365 are controlled to open the second branch passage 352 and the sixth branch passage 356, respectively.

[0255] Next, we will explain the case in which the incoming mixed fluid passes through the first filter member 311 and the second filter member 312 and then flows into the outflow channel section 220.

[0256] In this case, the first filter member 311 must communicate with the second filter member 312. For this purpose, the first branch valve 361 and the third branch valve 363 are controlled to open the first branch passage 351 and the third branch passage 353, respectively. At the same time, the second branch valve 362 is controlled to close the second branch passage 352.

[0257] Furthermore, the second filter member 312 must block communication with the third filter member 313. For this purpose, the fourth branch valve 364 and the sixth branch valve 366 are controlled to close the fourth branch passage 354 and the seventh branch passage 367, respectively.

[0258] Furthermore, a bypass path must be formed for the second filter member 312 to flow into the outflow channel 220 without passing through the third filter member 313. For this purpose, the fifth branch valve 365 is controlled to open the sixth branch channel 356.

[0259] Next, we will explain the case in which the incoming mixed fluid passes through the first filter member 311 and the third filter member 313 and then flows into the outflow channel section 220.

[0260] In this case, the first filter member 311 must block communication with the second filter member 312. To this end, the first branch valve 361 is controlled to close the first branch passage 351, and the second branch valve 362 is controlled to open the second branch passage 352. This creates a bypass path through which any one of the fluids that has passed through the first filter member 311 flows around the second filter member 312.

[0261] Furthermore, the second branch passage 352 must communicate with the third filter member 313. For this purpose, the fifth branch valve 365 is controlled to close the sixth branch passage 356, and the fourth branch valve 364 is controlled to open the fourth branch passage 354.

[0262] In this case, the third branch valve 363 is controlled to close the third branch passage 353, preventing any one of the fluids from flowing back into the second filter member 312. Also, the sixth branch valve 366 is controlled to open the seventh branch passage 357, allowing any one of the fluids that has passed through the third filter member 313 to flow into the outlet passage 220.

[0263] Therefore, the multiple branch valves 360 operate independently and in a corresponding manner to each other, allowing for the formation of diverse fluid flow paths for any one of the fluids.

[0264] The condition adjustment unit 400 is configured to adjust the physical state of the mixed fluid flowing in the fluid separation unit 300 or any one of the separated fluids. The condition adjustment unit 400 can improve the separation efficiency of the mixed fluid and the phase change and capture efficiency of any one of the separated fluids.

[0265] The condition adjustment unit 400 is connected to the fluid separation unit 300. The condition adjustment unit 400 may be provided in any form that can adjust the state of the mixed fluid or any one of the fluids flowing in the fluid separation unit 300. In one embodiment, the condition adjustment unit 400 may be configured to adjust the temperature of the mixed fluid or any one of the fluids by heating or cooling the fluid separation unit 300.

[0266] In the illustrated embodiment, the condition adjustment unit 400 includes a heating member 410 and a cooling member 420.

[0267] The heating element 410 heats the mixed fluid that flows into the fluid separation section 300 and maintains it in the gas phase. This improves the separation efficiency of the mixed fluid in the filter element 310.

[0268] The heating element 410 is connected to the filter element 310. In embodiments where multiple filter elements 310 are provided, the heating element 410 may be connected to each of the multiple filter elements 310 and configured to selectively heat each of the multiple filter elements 310.

[0269] In the illustrated embodiment, the heating member 410 is connected to the first to third filter members 311, 312, and 313, respectively. In the above embodiment, the heating member 410 may be configured to heat the first to third filter members 311, 312, and 313 independently of each other.

[0270] The heating element 410 may be provided in any form that can heat other elements to raise their temperature. In one embodiment, the heating element 410 may be provided in the form of a heater.

[0271] The cooling element 420 cools one of the separated fluids, causing it to condense into a liquid phase. This improves the phase change and capture efficiency of the separated fluid.

[0272] The cooling member 420 is connected to the capture member 320. The cooling member 420 may be provided in any form that can cool any one of the fluids that flows into the interior of the capture member 320. In one embodiment, the cooling member 420 may be provided in the form of a chiller.

[0273] The utility unit 500 is configured to sense the state of either the mixed fluid or the separated fluid flowing in the flow path unit 200. The utility unit 500 is also configured to adjust the flow of either the mixed fluid or the separated fluid.

[0274] The utility section 500 is provided in the flow path section 200. In the illustrated embodiment, the utility section 500 is provided in the inflow flow path section 210 and the outflow flow path section 220. Optionally, the utility section 500 may also be provided on the exhaust flow path section 230 and the capture flow path section 240.

[0275] The utility unit 500 is electrically connected to an external control unit (not shown). Electric power and control signals required for the utility unit 500 to operate can be transmitted from the external control unit (not shown). Various types of information sensed by the utility unit 500 can be transmitted to the external control unit (not shown) in the form of electrical signals.

[0276] In the illustrated embodiment, the utility unit 500 includes a particle filter member 510, a pressure adjustment member 520, a flow rate adjustment member 530, a sensor member 540, and a valve member 550.

[0277] The particle filter member 510 is configured to filter particulate matter present on the mixed fluid that has flowed in through the inflow communication portion 110. The inflowing mixed fluid can flow into the fluid separation unit 300 after the particulate matter is removed. This prevents clogging of the fluid separation unit 300 and can improve the separation efficiency in the fluid separation unit 300.

[0278] The particle filter member 510 may be provided in any form capable of filtering particulate matter. In one embodiment, the particle filter member 510 may be provided to include a mesh-type filter having a plurality of through-holes.

[0279] The particle filter member 510 may be arranged to be biased toward the upstream side of the flow path unit 200. This is to filter the particulate matter after the mixed fluid enters the inflow flow path portion 210 and before it flows to other components. In the embodiment illustrated in Figure 2, the particle filter member 510 is located on the downstream side of the valve member 550 so as to be adjacent to the inflow communication portion 110.

[0280] The pressure adjustment member 520 is configured to adjust the pressure of the mixed fluid flowing inside the flow path unit 200 or within the flow path unit 200. By forming negative pressure or positive pressure, the pressure adjustment member 520 allows the mixed fluid to flow inside the flow path unit 200 without a separate transfer member.

[0281] The pressure adjusting member 520 may be provided in any form capable of adjusting pressure. In one embodiment, the pressure adjusting member 520 may be provided in the form of a compressor or a pump.

[0282] The pressure adjusting member 520 may be arranged to be biased toward the upstream side of the flow path part 200. This is to adjust the pressure immediately after the mixed fluid flows into the inflow flow path part 210, so that the fluid can flow rapidly. In the embodiment illustrated in Figure 2, the pressure adjusting member 520 is located on the downstream side of the particle filter member 510 so as to be adjacent to the inflow communication part 110.

[0283] The flow rate adjusting member 530 is configured to adjust the flow velocity of the mixed fluid flowing inside the flow path part 200. Thereby, the flow rate of the mixed fluid flowing inside the flow path part 200 can also be adjusted.

[0284] The flow rate adjusting member 530 may be provided in any form capable of adjusting the flow velocity or flow rate of the flowing fluid. In one embodiment, the flow rate adjusting member 530 may be provided in the form of a butterfly valve.

[0285] The sensor member 540 is configured to sense information related to the state of the mixed fluid or any one of the fluids flowing in the flow path part 200. The sensor member 540 can transmit the sensed information to an external control unit (not shown).

[0286] A plurality of the sensor members 540 may be provided. The plurality of sensor members 540 may be arranged at various positions of the flow path part 200. In the illustrated embodiment, a part of the sensor members 540 is arranged in the inflow flow path part 210 to sense information related to the state of the mixed fluid. The other part of the sensor members 540 is arranged in the outflow flow path part 220 to sense information related to the state of any one of the fluids.

[0287] The sensor member 540 may be provided in any form capable of sensing information regarding the state of the flowing fluid. In the illustrated embodiment, the sensor member 540 includes a flow sensor 541 and a pressure sensor 542.

[0288] Although not shown in the diagram, the sensor member 540 may further include sensors for sensing the flow velocity, temperature, etc., of the flowing fluid.

[0289] The flow sensor 541 senses information regarding the flow rate of the fluid flowing in the flow channel 200. The sensed information is transmitted to an external control unit (not shown) and used to calculate control information for controlling the flow velocity adjustment member 530. In other words, in one embodiment, the operation of the flow velocity adjustment member 530 can be controlled in conjunction with the information sensed by the flow sensor 541.

[0290] Multiple flow sensors 541 may be provided. Each of the multiple flow sensors 541 can sense information regarding the flow rate of the mixed fluid and any one of the fluids.

[0291] In the illustrated embodiment, two flow sensors 541 are provided. One of the flow sensors 541 is located on the inflow channel section 210, between the pressure regulating member 520 and the filter member 310, and senses information regarding the flow rate of the mixed fluid.

[0292] Another flow sensor 541 is located on the outflow channel section 220, between the outflow communication section 120 and the capture member 320, and senses information regarding the flow rate of either one of the fluids.

[0293] The pressure sensor 542 senses information regarding the pressure of the fluid flowing in the flow path 200. The sensed information is transmitted to an external control unit (not shown) and used to calculate control information for controlling the pressure regulating member 520. In other words, in one embodiment, the operation of the pressure regulating member 520 can be controlled in conjunction with the information sensed by the pressure sensor 542.

[0294] Multiple pressure sensors 542 may be provided. Each of the multiple pressure sensors 542 can sense information regarding the pressure of the mixed fluid and any one of the fluids.

[0295] In the illustrated embodiment, two pressure sensors 542 are provided. One of the pressure sensors 542 is located on the inflow channel 210, between the flow sensor 541 and the filter member 310, and senses information regarding the pressure of the mixed fluid.

[0296] Another pressure sensor 542 is located on the outflow channel section 220, between the filter member 310 and the capture member 320, and senses information regarding the pressure of either one of the fluids.

[0297] The valve member 550 allows or blocks communication between the flow path section 200 and the communication section 100. This allows external mixed fluid to flow into or block its inflow into the fluid recovery system 10.

[0298] The valve member 550 may be positioned adjacent to the upstream side of the flow path 200. In the illustrated embodiment, the valve member 550 is positioned downstream of the inflow communication section 110, adjacent to the upstream end of the inflow flow path 210.

[0299] Therefore, when the valve member 550 opens the inflow channel 210, the external mixed fluid flows into the fluid recovery system 10, flows, and is separated. When the valve member 550 closes the inflow channel 210, the external mixed fluid no longer flows into the fluid recovery system 10.

[0300] (2) Description of the configuration of the fluid recovery system 20 according to other embodiments of the present invention Referring to Figures 3 and 4, a fluid recovery system 20 according to another embodiment of the present invention is illustrated.

[0301] The fluid recovery system 20 according to the present embodiment further includes a fluid recovery unit 600, and any one fluid discharged and recovered via the outflow flow path unit 220 and the outflow communication unit 120 can be supplied again via the inflow communication unit 110. That is, the fluid recovery system 20 according to the present embodiment can be defined as a circulation-type system.

[0302] Therefore, in the fluid recovery system 20 according to the present embodiment, any one fluid discharged via the outflow communication unit 120, that is, the remaining fluid that has not undergone phase change and has not been captured, can go through the separation and recovery process again. Thereby, the recovery efficiency of any one fluid can be improved.

[0303] In the illustrated embodiment, the fluid recovery system 20 includes a communication unit 100, a flow path unit 200, a fluid separation unit 300, a condition adjustment unit 400, a utility unit 500, and a fluid recovery unit 600.

[0304] Except for the fluid recovery unit 600 and the coupling and communication relationship between the fluid recovery unit 600 and other components, the other components and the coupling relationship between the respective components are the same as those of each component of the fluid recovery system 10 according to the aforementioned embodiment. Accordingly, the descriptions related to the communication unit 100, the flow path unit 200, the fluid separation unit 300, the condition adjustment unit 400, and the utility unit 500 shall be replaced with the above descriptions.

[0305] The fluid recovery unit 600 is coupled to and communicates with the communication unit 100. Any one fluid discharged via the outflow communication unit 120 can flow through the fluid recovery unit 600 to the inflow communication unit 110. The fluid recovery unit 600 is coupled to and communicates with the inflow communication unit 110 and the outflow communication unit 120 respectively.

[0306] In the illustrated embodiment, the fluid recovery unit 600 includes a recovery flow path unit 610, a recovery compressor 620, and a recovery valve 630.

[0307] The recovery channel section 610 connects the inlet communication section 110 and the outlet communication section 120. The remaining fluid discharged through the outlet communication section 120 can be supplied to the inlet communication section 110 via the recovery channel section 610.

[0308] The recovery compressor 620 is connected to and communicates with the recovery flow channel 610. The recovery compressor 620 provides a transfer force to the remaining fluid flowing inside the recovery flow channel 610. The remaining fluid can flow from the outlet communication section 120 through the recovery flow channel 610 to the inlet communication section 110 by the transfer force provided by the recovery compressor 620.

[0309] Furthermore, the recovery compressor 620 adjusts the pressure of the remaining fluid flowing inside the recovery channel section 610. This allows for proper adjustment of the pressure of the fluid flowing into the inlet communication section 110.

[0310] The recovery valve 630 opens or closes the recovery flow path 610. As the recovery valve 630 operates, it can allow or block communication between the inlet communication 110 and the outlet communication 120.

[0311] The recovery valve 630 may be provided in any form that can open or close the recovery flow path 610. In one embodiment, the recovery valve 630 may be provided in the form of a solenoid valve that is operated by an electrical signal.

[0312] The operation of the recovery valve 630 can be linked to the operation of the branch valve 360. That is, the recovery valve 630 is controlled to open the recovery channel section 610 when either the fifth branch valve 365 or the sixth branch valve 366 is controlled to open either the sixth branch channel 356 or the seventh branch channel 357.

[0313] Therefore, when the remaining fluid passes through the fluid separation section 300, the inlet communication section 110 and the outlet communication section 120 communicate with each other, allowing the other fluid to circulate again.

[0314] 3. Description of the fluid recovery method according to the embodiment of the present invention The fluid recovery method according to the embodiments of the present invention can be carried out using the fluid recovery systems 10 and 20 according to the respective embodiments described above. The fluid recovery method can effectively capture and recover any one of the fluids to be recovered from among a plurality of fluids mixed in a mixed fluid.

[0315] The fluid recovery methods according to each embodiment of the present invention will be described in detail below with reference to Figures 5 to 11.

[0316] (1) Description of a fluid recovery method according to one embodiment of the present invention Referring to Figures 5 to 9, a fluid recovery method according to one embodiment of the present invention is illustrated. The fluid recovery method according to this embodiment can be performed using a fluid recovery system 10 according to one embodiment of the present invention.

[0317] In the illustrated embodiment, the fluid recovery method includes the steps of: a step in which a fluid separation unit 300 receives a mixed fluid (S100); a step in which the fluid separation unit 300 separates the received mixed fluid into at least two other fluids (S200); a step in which a portion of one of the at least two other fluids is captured (S300); and a step in which the remainder of one of the at least two other fluids and the other fluids are discharged (S400).

[0318] Referring to Figure 6, the step (S100) in which the fluid separation unit 300 receives the mixed fluid will be described in detail. In this step (S100), the mixed fluid is supplied from the outside and flows along the flow path 200 to the fluid separation unit 300.

[0319] First, the mixed fluid flows into the inlet communication section 110 (S110). For this purpose, the valve member 550 is controlled to open the inlet flow path section 210. The incoming mixed fluid first passes through the particle filter member 510 to remove particulate matter.

[0320] The pressure of the mixed fluid flowing along the inflow channel 210 is adjusted by the pressure adjustment member 520 (S120). This also allows for adjustment of the flow rate or flow velocity of the mixed fluid.

[0321] The mixed fluid that flows into the fluid separation section 300 flows into a filter member 310 located at the uppermost side of the fluid separation section 300 and communicating with the inflow channel section 210 (S130).

[0322] Referring to Figure 7, the step (S200) in which the fluid separation unit 300 separates the transmitted mixed fluid into at least two other fluids will be described in detail. In this step (S200), the mixed fluid that flows into the fluid separation unit 300 passes through the filter member 310 and is separated into multiple fluids (S200).

[0323] The mixed fluid that flows along the inflow channel 210 flows into the filter member 310 (S210). In this case, multiple filter members 310 are provided, and these multiple filter members 310 can be connected to or disconnected from each other by multiple branch channels 350 and multiple branch valves 360.

[0324] However, as mentioned above, in either case, the incoming mixed fluid flows in such a way that it passes through at least one filter member 310 before being discharged.

[0325] Of the mixed fluids that flow into the filter member 310, one fluid that is to be captured and recovered is separated by passing through the filter member 310 along the extension direction of the filter member 310 (S220).

[0326] In this process, the heating element 410 can heat the mixed fluid that flows into the filter element 310. This improves the separation efficiency of the mixed fluid.

[0327] Furthermore, of the mixed fluid that flows into the filter member 310, the other fluids to be separated and discharged are separated by passing through a membrane provided on the filter member 310 along the other direction of the filter member 310 (S230).

[0328] In one embodiment, the other direction of the filter member 310 may be the radial direction. This corresponds to an embodiment in which the filter member 310 is provided in the form of a membrane filter.

[0329] When the mixed fluid passes through multiple filter members 310, any one of the fluids separated by the upstream filter member 310, for example, the first filter member 311, can flow into the second filter member 312 or the third filter member 313. Furthermore, any one of the fluids separated by the second filter member 312 or the third filter member 313 may undergo the separation process again in step (S220).

[0330] Referring to Figure 8, the step (S300) of capturing a portion of one of the at least two other separated fluids will be described in detail. This step (S300) is the step (S300) of capturing, discharging, and recovering one of the fluids separated from the mixed fluid that is to be captured and recovered.

[0331] Any one of the fluids separated from the mixed fluid after passing through the filter member 310 flows into the capture member 320 (S310). Any one of the fluids that flows into the capture member 320 is liquefied and captured (S320).

[0332] In this process, one of the fluids can be cooled by the flow path heat dissipation member 250 before it flows into the capture member 320. Furthermore, one of the fluids that flows into the capture member 320 can be cooled by the cooling member 420.

[0333] In the illustrated embodiment, it is shown that a portion of one of the fluids is liquefied and captured. This takes into account that in actual processes, it is difficult for one of the fluids to be completely liquefied and captured, and it is understood that it is most preferable for the entire fluid of one of the fluids to be liquefied and captured.

[0334] One of the captured fluids flows along the capture channel section 240 which communicates with the capture member 320 and is contained in the tank member 330. The one of the fluids contained in the tank member 330 flows due to the transfer force applied by the transfer member 340 and is discharged and recovered via the capture communication section 140 (S330).

[0335] Referring to Figure 9, the step (S400) of discharging the remainder of at least one of the other fluids that have been separated, as well as the other fluids, will be described in detail. This step (S400) is the step of discharging to the outside any one of the fluids that has been separated from the mixed fluid but has not yet been captured and recovered, as well as the other fluids that have been separated from the mixed fluid.

[0336] First, the other fluids separated from the mixed fluid flow along the exhaust passage section 230 and are discharged to the outside through the exhaust communication section 130 (S410). As mentioned above, in embodiments in which multiple filter members 310 are provided, multiple exhaust passage sections 230 and exhaust communication sections 130 are also provided and can communicate with each of the multiple filter members 310.

[0337] Furthermore, any remaining fluid that remains after passing through the fluid separation section 300 without being separated flows along the outlet channel section 220 and is discharged and recovered to the outside via the outlet communication section 120 (S420).

[0338] (2) Description of fluid recovery method according to other embodiments of the present invention Referring to Figures 10 to 11, a fluid recovery method according to another embodiment of the present invention is illustrated.

[0339] The fluid recovery method according to this embodiment can be performed using the fluid recovery system 20 according to the other embodiments described above.

[0340] In the illustrated embodiment, the fluid recovery method includes the steps of: receiving the mixed fluid from the fluid separation unit 300 (S100); separating the received mixed fluid from at least two other fluids (S200); capturing a portion of one of the separated at least two other fluids (S300); discharging the remainder of one of the separated at least two other fluids and the other fluids (S400); and having the remainder of one of the fluids re-transmitted to the fluid separation unit 300 via the fluid recovery unit 600 (S500).

[0341] Steps S100, S200, S300, and S400 of the fluid recovery method according to this embodiment are the same as those of the fluid recovery method according to the previously described embodiment.

[0342] From here on, the explanation will focus on the S500 stage.

[0343] Referring to Figure 11, the step (S500) in which the remainder of one of the fluids is again transmitted to the fluid separation unit 300 via the fluid recovery unit 600 will be described in detail. In this step (S500), the one of the fluids that has been separated from the mixed fluid but has not yet been captured and recovered flows back into the fluid separation unit 300, and the separation process is repeated (S500).

[0344] The remaining fluid that has passed through the capture member 320 but has not undergone a phase change or been captured flows along the outflow channel section 220. The remaining fluid that has flowed flows into the recovery channel section 610 via the outflow communication section 120 (S510).

[0345] The recovery compressor 620 adjusts the remaining pressure of one of the incoming fluids (S520). This adjusts the remaining velocity and pressure of the one fluid, allowing the remaining fluid to be stably supplied to the inlet communication section 110.

[0346] The remainder of one of the incoming fluids flows along the inflow channel 210 and is then transmitted to the fluid separation section 300 (S530). Subsequently, the fluid separation section 300 receives the mixed fluid (S100), separates the received mixed fluid into at least two other fluids (S200), captures a portion of one of the separated at least two other fluids (S300), and discharges the remainder of one of the separated at least two other fluids and the other fluids (S400), and the separation process may be repeated.

[0347] While embodiments of the present invention have been described, the spirit of the present invention is not limited by the embodiments presented herein. Those skilled in the art who understand the spirit of the present invention can easily propose other embodiments within the same spirit by adding, changing, deleting, or adding components, and these too can be said to fall within the spirit of the present invention.
