In this embodiment, the membrane layer 200 is, for example, a membrane layer 200 that allows water vapor to pass through but is difficult for air to pass through. After the air can enter the separation device 10 from the air inlet 12, the water vapor in the air passes through the membrane layer 200, so that the air at the outlet 329 has a lower humidity. Of course, the type of the film layer 200 and the type of the first component F1 to be separated are not limited thereto. The membrane layer 200 is also called a selective membrane, and the membrane layer 200 can be, for example, a water separation composite membrane disclosed in Taiwan Patent 1565517, other composite membranes containing graphene oxide, a zeolite membrane, a polymer membrane sulfonated poly(ether ether ketone) (SPEEK), polyether block amide (

1074), or a composite membrane composed of other hydrophilic polymers and salts (polyvinyl alcohol PVA + lithium chloride LiCl). Of course, the type of the film layer 200 is not limited to the above.

As shown in FIG. 2 , in this embodiment, each capsule 100 includes a flow channel forming structure 110 located in the middle and an outer frame portion 120 located around it. The flow channel forming structure 110 has a plurality of flow channels 111 . These flow channels 111 are partially exposed on opposite surfaces of the capsule 100 . In this embodiment, the flow channel forming structure 110 includes a plurality of flow guide bars 112, and the flow channels 111 are formed between the flow guide bars 112, but the form of the flow channel forming structure 110 is not limited thereto.

In this embodiment, the outer frame portion 120 includes a plurality of air suction ports 122 , and the air suction ports 122 communicate with the flow channels 111 .

The membrane layers 200 are disposed on the upper and lower surfaces of the two membrane boxes 100 where the flow channels 111 are exposed. In other words, the film layers 200 shield the exposed portions of the flow channels 111 . As shown in FIG. 2 , in this embodiment, the number of membrane layers 200 of the separation device 10 is taken as an example, and the four membrane layers 200 are respectively arranged on the upper side of the two-flow channel forming structures 110 of the two membrane boxes 100 . with the underside.

The sintered mesh is made of stainless steel wire wound and then hot-pressed and sintered. The porosity is greater than 50%. time does not collapse. Of course, the material of the mesh support layer 210 is not limited thereto.

When the separation device 10 is in operation, each bellows 100 will be evacuated at the air suction port 122, and the gas in the flow channel 111 will be drawn out, and the pressure will be negative. At this time, the membrane layer 200 will abut in the direction of the flow channel forming structure 110 , and the mesh support layer 210 is used to support the membrane layer 200 to prevent the membrane layer 200 from collapsing.

In addition, in this embodiment, when the film layer 200 is stacked on the mesh support layer 210, the area of the film layer 200 can be larger than the area of the mesh support layer 210, so that the surrounding area of the film layer 200 can be sealed by gluing or the like. on the flow channel forming structure 110 . In this way, it can be ensured that the surrounding of the membrane layer 200 will not leak, so that the first component F1 (eg, water vapor) in the fluid F can only pass through the membrane layers 200 and enter the flow channel 111 . Of course, in other embodiments, the periphery of the membrane layer 200 and the mesh support layer 210 can also be sealed on the flow channel forming structure 110 by other means such as snap-fit. The manner in which the membrane layer 200 and the mesh support layer 210 are sealed on the flow channel forming structure 110 is not limited thereto.

In this embodiment, due to the integrated structure of the flow channel forming structure 110 and the outer frame portion 120, the bellows 100 will not leak air from the joint between the flow channel forming structure 110 and the outer frame portion 120, and can maintain in a good negative pressure state. In addition, since the flow channel forming structure 110 is integrated with the outer frame portion 120, additional assembly is not required, and the manufacturing process can be reduced. Of course, in other embodiments, the flow channel forming structure 110 and the outer frame portion 120 may also be non-integrated, that is to say, the flow channel forming structure 110 and the outer frame portion 120 may also be two separate pieces, and then assembled through or glued together.

In this embodiment, the outer frame portion 120 includes two concave regions 124 located on both sides of the flow channel forming structure 110 , and the two concave regions 124 and the flow channel forming structure 110 together form the main flow channel 14 . In this embodiment, the extending direction of the main flow channel 14 is different from the extending direction of the flow channels 111 (for example, vertical), but not limited thereto.

In addition, in this embodiment, the flow direction adjustment structure 300 is disposed between the film layers 200 located on the inner sides of the two flow channel forming structures 110 . The fluid F flowing in from the air inlet 12 is adapted to pass through the flow direction adjustment structure 300 so that at least part of the fluid F flows to the membrane layers 200 . At this time, due to the negative pressure in the flow channel 111, the first component F1 (for example, water vapor) in the fluid F will pass through these membrane layers and flow along these flow channels 111 to the suction port 122, while the remaining air The flow will continue to leave the separation device 10 . That is to say, the separation device 10 of the present embodiment increases the probability of the fluid F flowing to the upper and lower membrane layers 200 through the flow direction adjustment structure 300 .

Figure 3 is a schematic diagram of a separation device according to another embodiment of the present invention. FIG. 4 is an exploded schematic view of the separation device of FIG. 3 . Please refer to FIG. 3 and FIG. 4 , in the separation device 10a of this embodiment, the form of the membrane box 100a is different from that of the membrane box 100 of the previous embodiment, which will be described later. In the separation device 10a of the present embodiment, the flow direction adjustment structure 300 is also arranged between the two membrane boxes 100a, and the fluid F flowing from the air inlet 12 flows to the membrane layers 200 more easily after passing through the flow direction adjustment structure 300, and the increase The probability of the first component F1 passing through the film layer 200 . The flow direction adjustment structure 300 will be described in detail below.

FIG. 5 is a partially enlarged schematic view of the flow direction adjustment structure of the separation device of FIG. 3 . FIG. 6 is a schematic view of the separation device of FIG. 3 in section along the line A-A. Referring to FIG. 5 and FIG. 6 , in this embodiment, the flow direction adjustment structure 300 includes a hollow structure. In this embodiment, the hollow structure includes, for example, a plurality of pipe bodies 310 . Of course, the types of hollow structures are not limited thereto. After entering the air inlet 12 , the fluid F enters these pipe bodies 310 and flows along the extending direction of the pipe bodies 310 . In this embodiment, the extending direction of the pipe body 310 is different from the extending direction of the flow channels 111 , but not limited thereto.

In this embodiment, each tube body 310 includes an open first end 311 , a closed second end 312 opposite to the first end 311 , and a plurality of openings 313 facing the membrane layers 200 . The openings 313 of the tubes 310 are close to the first end 311 . In this embodiment, the fluid F flowing in from the air inlet 12 is suitable for entering the pipe bodies 310 from the first ends 311 , and being ejected from the openings 313 to flow to the membrane layers 200 , increasing the flow of the fluid F up and down two The probability of film layer 200.

After simulation, if the length of the tube body 310 is taken as an example of 20 cm, the tube body 310 is provided with openings 313 at a distance of 1 cm from the first end 311 in the direction toward each membrane layer 200, and there will be one opening in sequence. The tube body 310 with the hole 313 (the opening 313 of which is located at 1 cm from the first end 311 ), the tube body 310 with two openings 313 (the two openings 313 are located at 1 cm and 2 cm from the first end 311 ) ), ..., the pipe body 310 with 10 openings 313 is simulated respectively. When the number of openings 313 in the tube body 310 is 1 to 2, the mass transfer rate can be maintained above 2, and the pressure drop can be maintained above 800 Pa, which has a better effect. Therefore, in this embodiment, the number of openings 313 in the tube body 310 in the direction toward each membrane layer 200 is two, and the location of the openings 313 is not more than 5 cm near the first end 311 , for example, 1 cm and 3 cm. After simulation, the velocity of the fluid F ejected from the opening 313 can be maintained between 20 m/s and 30 m/s.

The parts of the membrane extend up and down in the direction of these membrane layers 200 to guide the fluid F to flow in the direction of the membrane layers 200 . Through simulation, the configuration of the deflector 314 can effectively improve the mass transfer rate of water vapor.

It should be noted that if 2, 4, 6 and 8 baffles 314 are arranged on the upper and lower sides of the pipe body 310 with two openings 313 and close to the first end 311 to simulate the fluid F state , when the number of the guide plates 314 is more than 4, the mass transfer rate can be maintained above 2, and the mass transfer rate of the eight guide plates 314 is 2.45, which has the best mass transfer rate. Therefore, in this embodiment, the upper side and the lower side of the pipe body 310 are respectively provided with eight baffles 314 . According to the simulation results, in the separation device 10 with the flow direction adjustment structure 300 , the water capture amount (mass transfer ratio) of the membrane layer 200 can be increased by 2.5 times to 3 times.

It is worth mentioning that the bellows 100a of the separation device 10a of this embodiment is slightly different from the bellows 100 of the previous embodiment. One of the differences is that, referring to FIGS. 2 and 4 at the same time, it can be seen that in the capsule 100a of the present embodiment, the outer frame portion 120 does not have two concave regions 124 (marked on the upper and lower sides of the flow channel forming structure 110 ) 2), that is, the outer frame portion 120 of the membrane box 100a may not have a height difference.

Another difference is that FIG. 7A and FIG. 7B are schematic diagrams of different viewing angles of the bellows of FIG. 4 along the section of the B-B line segment, respectively. Referring to FIGS. 7A and 7B , in the bellows 100 a of the present embodiment, the guide strips 112 of the flow channel forming structure 110 extend to the position of the outer frame portion 120 close to the air suction port 122 , and the outer frame portion 120 is increased in Structural strength of the site close to the exhaust port 122 . In addition, among these guide bars 112 , the length of the guide bars 112 close to the air suction port 122 is greater than the length of the guide bars 112 away from the air suction port 122 . That is to say, the structural strength of the outer frame portion 120 is better as it is closer to the air suction port 122 , so as to reduce the probability of collapse of the upper and lower plates of the outer frame portion 120 during vacuuming. In addition, the outer frame portion 120 has a wall surface inclined to the air extraction opening 122 near the air extraction opening 122 , so as to guide the airflow during vacuuming.

Of course, although the above-mentioned flow channel forming structure 110 is formed by a plurality of flow guide bars 112 arranged side by side, the form of the flow channel forming structure 110 is not limited to this. 8 is a schematic side view of a flow channel forming structure according to another embodiment of the present invention.

The other flow direction adjustment structures 300b, 300c, and 300d are described below. 9 and 10 are schematic diagrams of a flow direction adjustment structure according to another embodiment of the present invention. Referring to FIGS. 9 and 10 , in this embodiment, the flow direction adjusting structure 300 b includes a plurality of ribs 320 , a plurality of first baffles 326 and a plurality of second baffles 327 .

These ribs 320 are arranged side by side to form a plurality of sub-channels 325 . In this embodiment, the extending direction of the sub-flow channels 325 is different from the extending direction of the flow channels 111 , but not limited thereto.

The ribs 320 have opposite first ends 321 and second ends 322 , the first baffles 326 are arranged on the first ends 321 of the ribs 320 , the second baffles 327 are arranged on a plurality of the sub-channels 325 end. That is to say, the first baffle 326 and the second baffle 327 are arranged in a staggered manner. As can be seen in FIG. 10 , the heights of the first baffles 326 and the second baffles 327 are greater than the heights of the ribs 320 and equal to the distance between the two film layers 200 . A plurality of inlets 328 are formed between the first baffles 326 and the upper and lower membrane layers 200 of the flow direction adjustment structure 300b, and a plurality of outlets 329 are formed at the second baffles 327 and the second ends 322 of the ribs 320, and the upper and lower membranes 200. between the film layers 200 . The outlets 329 are respectively staggered from the inlets 328 .

The space between the top surface 323 of the ribs 320 and the adjacent membrane layers 200 will communicate with the sub-channels 325, and the bottom surfaces 324 of the ribs 320 are connected to the adjacent film layers 200. The spaces between the membrane layers 200 are communicated with these sub-channels 325 . Therefore, after the fluid F enters the inlets 328 of the flow direction adjustment structure 300b, the sub-channels 325, the spaces between the top surfaces 323 of the ribs 320 and the adjacent membrane layers 200, the bottom surfaces 324 of the ribs 320 and the The space between the adjacent membrane layers 200 flows, thereby increasing the probability of the fluid F flowing to the upper and lower membrane layers 200 .

In this embodiment, the spoilers 330 include a plurality of blocking pieces 332 , 334 that are staggered in height, and the blocking pieces 332 , 334 are arranged along one direction and fixed between the two frames 331 . In the present embodiment, since the baffles 332 and 334 are arranged alternately up and down, the fluid F will flow up and down because of the baffles 332 and 334 when passing through the flow direction adjustment structure 300 c , which increases the flow of the fluid F to the upper and lower membrane layers 200 . chance.

In this embodiment, the height of the frame 331 is H1, because when the flow direction adjustment structure 300c of this embodiment is applied to the separation device, the two membrane boxes 100a (marked in FIG. 4 ) will be separated by the frame 331 of the flow direction adjustment structure 300c , therefore, the distance between the two capsules 100a is close to H1. It can also be said that the overall height of the fluid F when passing between the two bellows 100a is close to H1. In this embodiment, the heights of the blocking pieces 332 and 334 are H2, and H2 is 20% to 50% of H1. That is to say, in this embodiment, the height H2 of the baffles 332 and 334 is 20% to 50% of the overall height of the fluid F when it passes between the two bellows 100a. Such a design can make the fluid F still maintain good fluidity when passing between the two bellows 100a, and the flow direction can be adjusted according to the flow direction adjustment structure 300c.

In addition, in this embodiment, an angle θ is formed between the extending direction of the blocking pieces 332 and 334 and the plane of the frame 331 . In this embodiment, the extending directions of the blocking pieces 332 and 334 are, for example, perpendicular to the plane of the frame 331 , so that the angle θ between them is 90 degrees.
