Description

Technical Field

[0001] This utility model relates to the field of fluid transport control device design, and in particular to a fluid transmembrane channel transport sealing device and system. Background Technology

[0002] Compared to traditional multiphase separation methods, membrane separation offers advantages such as simple operation, economy, low consumption, high efficiency, and continuous transmembrane transport at room temperature. Liquid-gated technology, as an emerging high-efficiency membrane separation technology, utilizes a combination of gated liquids and porous solid frameworks to address two major limitations in current membrane separation processes: easy fouling and inefficient membrane separation performance, achieving foul-free and highly efficient transmembrane transport. However, in practical applications, the design of transport and separation devices using liquid-gated technology still has several shortcomings in terms of sealing, device versatility, and ease of installation. For example, the sealing reliability of traditional devices cannot be guaranteed; if the membrane clamping mechanism is too loose, leakage will occur, while if it is too tight, the sealing silicone will deform severely, also leading to leakage. Furthermore, traditional transmembrane transport sealing devices have low transport efficiency, only capable of transporting a single phase and unable to achieve multiphase fluid transport and separation. Traditional sealing devices also have fixed dimensions and specifications, making them unsuitable for different sizes and types of separation membranes, thus presenting certain limitations. Furthermore, existing sealing devices on the market cannot be fixed to instruments and equipment, have poor compatibility with instruments, are inconvenient to install and disassemble, and pose significant safety hazards.

Detailed Implementation

[0026] In this invention, the terms "first" and "second" are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be interpreted as indicating or implying relative importance.

[0027] Please see Figure 1-3 As shown, a fluid transmembrane pore transport sealing device includes a device body with an air inlet and an air / liquid outlet. The device body contains a receiving space for accommodating a sheet-like membrane, which is connected to both the air inlet and the air / liquid outlet. A support mesh is positioned between the air inlet and the air / liquid outlet within the receiving space. The sheet-like membrane is located on the side opposite to the support mesh and the air / liquid outlet. The air inlet, the receiving space, and the air / liquid outlet form a transmembrane transport separation pathway. Sealing rings are provided on both sides of the support mesh, and the two sealing rings abut against the inner wall of the receiving space. Different sizes of sealing rings and support meshes can be installed in the receiving space, thus enabling adaptation to sheet-like membranes of different sizes, shapes, and types, making the device highly versatile.

[0028] Specifically, the present invention provides a fluid transmembrane channel transport sealing device, including a gas transmembrane sealing device 1 and a liquid transmembrane sealing device 2. For ease of distinction, the similar structures of the gas transmembrane sealing device 1 and the liquid transmembrane sealing device 2 are distinguished by the terms "first" and "second".

[0029] like Figure 1 , Figure 2 As shown, the gas transmembrane sealing device 1 includes a first device body, which has a first air inlet 112 and an air outlet 1221. The first device body has a first accommodating space 111 for accommodating a sheet membrane 3. The first accommodating space 111 is connected to the first air inlet 112 and the air outlet 1221 respectively. A first support net 13 is provided between the first air inlet 112 and the air outlet 1221 in the first accommodating space 111. The sheet membrane 3 is located on the side opposite to the first support net 13 and the air outlet 1221. The first air inlet 112, the first accommodating space 111, and the air outlet 1221 form a transmembrane transport and separation channel.

[0030] First sealing rings 14 are provided on both sides of the first support mesh 13, and the two first sealing rings 14 abut against the inner wall of the first accommodating space 111. The material of the first sealing rings 14 can be elastic materials such as silicone, rubber, and urethane, but is not limited to these.

[0031] The first device body includes a first pool body 11 and a first sealing cover 12. The first pool body 11 is provided with a first protrusion 113 and a first groove 114. The first sealing cover 12 is detachably fixedly covered outside the first protrusion 113 and surrounds the first groove 114 to form a first accommodating space 111. The first pool body 11 is provided with the first air inlet 112 and the first sealing cover 12 is provided with an air outlet 1221.

[0032] Specifically, the first sealing cover 12 includes a cover body 121 and an air outlet 122. The cover body 121 is connected to the first protrusion 113 of the first pool body 11 to form an installation cavity 116. One end of the air outlet 122 is located inside the installation cavity 116 and forms a first accommodating space 111 with the first groove 114. The other end of the air outlet 122 extends out of the installation cavity 116, and the air outlet 122 is provided with an air outlet 1221. The cover body 121 is provided with an installation opening 1211, and a viewing window 15 is fixed at the installation opening 1211. The viewing window 15 is provided with a clearance opening 151 that allows the other end of the air outlet 122 to extend out of the installation cavity 116. The viewing window 15 is made of transparent material and can be used to observe the transmembrane transport process. The end of the first pool body 11 opposite to the first sealing cover 12 is provided with an elastic buckle 115. The elastic buckle 115 allows for easy assembly onto equipment and instruments, making installation and disassembly convenient and quick. The first pool body 11 and the cover body 121 are connected by threads, but are not limited to this. In other embodiments, they can also be connected by other means such as snap-fit ​​or screw fixing. The first air inlet 112 is connected to the pressure supply unit 10, and the air outlet 1221 is open to the atmosphere.

[0033] Before the instrument starts working, first, place one of the first sealing rings 14 and the first support net 13 into the first accommodating space 111 from bottom to top. Then, place the impregnated sheet membrane 3 on the first support net 13, followed by the other first sealing ring 14. Then, place one end of the air outlet 122 into the first accommodating space 111. Finally, screw the cover 121 and the first pool body 11 together to seal the first accommodating space 111, thus enabling transmembrane transport separation. When gas enters the portion of the first accommodating space 111 opposite to the first air inlet 112 through the first air inlet 112, when the pressure reaches the transmembrane threshold of the sheet membrane 3, the gas will be transported across the membrane and separated, entering the portion of the first accommodating space 111 opposite to the air outlet 1221, and then discharged through the air outlet 1221. When the sheet membrane 3 needs to be replaced, simply open the cover 121 by rotating it, take out the air outlet 122 and the other first sealing ring 14 in sequence, replace the sheet membrane 3, and then reinstall the other first sealing ring 14, air outlet 122 and cover 121 to retest.

[0034] Please see Figure 3As shown, the liquid transmembrane sealing device 2 includes a second device body, which has a second air inlet 212 and a liquid outlet 221. The second device body has a second accommodating space 211 for accommodating a sheet-like membrane. The second accommodating space 211 is connected to both the second air inlet 212 and the liquid outlet 221. A second support mesh 23 is disposed between the second accommodating space 211 and the liquid outlet 221. The sheet-like membrane is located on the side opposite to the liquid outlet 221 of the second support mesh 23. The second air inlet 212, the second accommodating space 211, and the liquid outlet 221 form a transmembrane transport and separation pathway. The second device body is made of a transparent material, allowing the instrument operator to easily observe the entire transmembrane transport process.

[0035] The second support mesh 23 is provided with a second sealing ring 24 on each side, and the two second sealing rings 24 abut against the inner wall of the second accommodating space 211. The material of the second sealing ring 24 can be elastic materials such as silicone, rubber, or urethane, but is not limited to these.

[0036] The second device body includes a second pool body 21 and a second sealing cover 22. The second pool body 21 is provided with a second protrusion 213, and the second protrusion 213 is provided with a second groove 214. The second sealing cover 22 is detachably fixedly covered outside the second protrusion 213 and surrounds the second groove 214 to form a second accommodating space 211. The second pool body 21 is provided with a second air inlet 212, and the second sealing cover 22 is provided with a liquid outlet 221. The second pool body 21 and the second sealing cover 22 are connected by threads, but are not limited to this. In other embodiments, they can also be connected by other methods such as snap-fit ​​or screw fixing.

[0037] The second pool body 21 also includes a liquid pool 215, which is connected to a second air inlet 212. Specifically, the second air inlet 212 is located at the top of the liquid pool 215, and the liquid pool 215 is connected to the second accommodating space 211 via a connecting pipe 26. An exhaust port 216 is also provided on the side where the second air inlet 212 of the second pool body 21 is located. The exhaust port 216 is connected to the second accommodating space 211 via an exhaust channel 217. A detachable end cap 25 is provided at the exhaust port 216.

[0038] Before the instrument starts working, first place one of the second sealing rings 24 and the second support net 23 into the second accommodating space 211 from left to right. Then, place the impregnated sheet membrane to the right of the second support net 23, and then place the other second sealing ring 24. Next, inject the test solution into the liquid pool 215, so that the test solution will reach the second accommodating space 211 along the connecting tube 26, and squeeze the original air in the second accommodating space 211. The air will be discharged from the exhaust port 216 at the top through the exhaust channel 217. After the gas is discharged, the test solution in the exhaust channel 217 will rise to the same liquid level as the test liquid in the liquid pool 215. At this time, tighten the end cap 25 and the exhaust port 216 to seal the exhaust port 216. Finally, connect the second air inlet 212 to the pressure supply unit 10. The gas entering from the second air inlet 212 will push the liquid in the liquid pool 215 into the part of the second containment space 211 opposite to the liquid pool 215. When the pressure in the second containment space 211 reaches the transmembrane threshold, the liquid will be transported and separated across the membrane, enter the part of the second containment space 211 opposite to the liquid outlet 221, and be discharged through the liquid outlet 221.

[0039] Please see Figure 4 As shown, the present invention provides a fluid transmembrane pore transport system, which includes a pressure supply unit 10 and a fluid transmembrane pore transport sealing device 20. The pressure supply unit 10 is connected to the air inlet of the sealing device 20 through an air guide pipe 30.

[0040] The pressure supply unit 10 provides pressure, which can be provided by an injection pump, a peristaltic pump, a pneumatic storage device, etc. The pressure supply unit 10 can be connected to multiple gas delivery lines 30, which push single-phase or multi-phase fluids such as gas, liquid, gas-liquid, and liquid-liquid through the sealing device 20, and finally achieve the separation and transport of single-phase or multi-phase fluids across the membrane pores through the sealing device 20, thereby realizing independent gas transport separation, independent liquid transport separation, gas-liquid mixed transport separation, and liquid-liquid mixed transport separation.

[0041] The present invention relates to a fluid transmembrane channel transport sealing device and system. The parts not described herein are the same as or can be implemented using existing technologies.

[0042] The above embodiments are only used to further illustrate a fluid transmembrane channel transport sealing device and system of the present invention.
