Description

TECHNICAL FIELD

[0001] The present application belongs to the field of gas-liquid separation, and particularly relates to a gas-liquid separator based on gradient filling of super-gas-wet super-gas-repellent particles and a separation method. BACKGROUND

[0002] Hydrogen energy is attracting attention for its high energy density and clean combustion products (water). As a secondary energy source, hydrogen energy can be produced through various means and does not produce carbon dioxide emissions when used, making it an important tool for addressing climate change. In recent years, with technological advances and policy support, the application range of hydrogen energy has been expanding, from transportation to industrial production, and the market potential of hydrogen energy is huge. Electrolysis of water is one of the main methods for producing green hydrogen, which refers to hydrogen produced through the electrolysis of water driven by renewable energy sources such as solar and wind energy. According to a study by the journal Nature, as the cost of renewable energy decreases and electrolysis technology advances, the economic viability of green hydrogen will further improve, driving its importance in the global energy market.

[0003] In the process of electrolysis of water to produce hydrogen, the design and performance of the gas-liquid separator are crucial to the overall efficiency and stability of the system. Current gas-liquid separator technology faces compatibility issues when combined with fluctuating renewable energy sources such as wind and solar energy. Traditional gravity-type gas-liquid separators require large volumes and long residence times to achieve effective separation, which results in the need for a large amount of electrolyte, thus prolonging the startup time of the electrolysis water equipment (as the electrolyte needs to be heated to the working temperature), and cannot quickly respond to fluctuating and intermittent energy sources. In addition, the separation efficiency of traditional gas-liquid separators is not high, making it difficult to achieve rapid separation, further limiting its compatibility with fluctuating energy sources. To solve these problems, research is exploring new high-efficiency gas-liquid separation technology to improve system response speed and adaptability.

[0004] To solve the above problems, the present application is proposed. SUMMARY

Example

[0037] Combine Figures 1 to 4 As shown, this embodiment proposes a gas-liquid separator based on a gradient filling of super-aerophilic and super-aerophobic particles, aiming to improve the separation efficiency and reduce the separation time of the gas-liquid separator. The separator comprises a gas-liquid inlet 1, a liquid outlet 2, a gas outlet 3, a super-aerophilic support mesh 4, a gas-liquid chamber 5, a bubble rise chamber 6, a gas capture chamber 7, a super-aerophilic corrugated baffle 8, particles 9, a large particle filling chamber 10, a small particle filling chamber 11, and a separator housing 12.

[0038] The particles 9 include super aerophilic large particles 91, super aerophobic large particles 93, super aerophilic small particles 92, and super aerophobic small particles 94;

[0039] The gas-liquid chamber 5 includes the bubble floating chamber 6 and the gas capture chamber 7;

[0040] The gas capture chamber 7 includes a large particle filling chamber 10 and the small particle filling chamber 11;

[0041] The large particle filling chamber 10 is filled with the super aerophilic large particles 91 and the super aerophobic large particles 93 in an orderly manner;

[0042] The small particle filling chamber 11 is filled with the super aerophilic small particles 92 and the super aerophobic small particles 94 in an orderly manner;

[0043] The super-aerophilic support mesh 4 is distributed on both sides of the large particle filling chamber 10 and / or the small particle filling chamber 11;

[0044] A plurality of super-aerophilic corrugated baffles 8 are provided inside the large particle filling chamber 10 and / or the small particle filling chamber 11, and the internal space between the super-aerophilic corrugated baffles 8 is filled with the particles 9;

[0045] The gas-liquid inlet 1 is located on the left side of the gas-liquid separator, and the liquid outlet 2 and the gas outlet 3 are located on the right side of the gas-liquid separator.

[0046] The super-gas-philic large particles 91 and the super-gas-repellent large particles 93 are mixed in the rightmost range of the large-particle filling chamber 10, and the super-gas-philic large particles 91 account for 30% of the particles 9 in the large-particle filling chamber 10.

[0047] The super-gas-philic small particles 92 and the super-gas-repellent small particles 94 are uniformly filled in the small-particle filling chamber 11, and the super-gas-philic small particles 92 account for 60% of the particles 9 in the small-particle filling chamber 11.

[0048] The super-gas-philic support net 4 is made of surface-modified hard stainless steel net, and the surface wettability of the super-gas-philic support net 4 is represented by the contact angle of liquid droplets. The contact angle of the super-gas-philic support net 4 is 110°, and the mesh number of the super-gas-philic support net 4 is 40.

[0049] The super-gas-philic corrugated baffle 8 is made of PTFE, and the distance between adjacent super-gas-philic corrugated baffles 8 is 1 cm.

[0050] The gas-liquid separator has three gas capturing chambers 7 inside, and adjacent two gas capturing chambers 7 do not contact, with a distance of 10 cm.

[0051] The large-particle filling chamber 10 is located on the left side of the gas capturing chamber 7, and the small-particle filling chamber 11 is located on the right side of the gas capturing chamber 7, forming a gradient filling from left to right.

[0052] Specifically, the gas capturing chamber 7 is tightly attached by the left large-particle filling chamber 10 and the right small-particle filling chamber 11. The large-particle filling chamber 10 is sequentially filled with super-gas-philic large particles 91 and super-gas-repellent large particles 93, and the average particle size is 5 mm equivalent diameter; the small-particle filling chamber 11 is uniformly mixed with super-gas-philic small particles 92 and super-gas-repellent small particles 94, and the average equivalent diameter of the particles is 500 μm.

[0053] Super aerophilic large particles 91, super aerophobic large particles 93, super aerophilic small particles 92, super aerophobic small particles 94, its internal material is all PTFE material, by super aerophilic, super aerophobic surface modification, be prepared into super aerophilic, super aerophobic particles.The mode of super aerophilic surface modification is: rinse PTFE particles with deionized water, remove dust or impurities that may exist on the surface.Then dry in an oven, ensure that the particle surface is free of moisture.Dry PTFE particles are evenly placed on the sample stage of a plasma treatment instrument. Ensure that particles do not overlap, use plasma to evenly process.Take out the PTFE particles after treatment, use sandblasting process, PTFE particle surface is roughened, before roughening, the liquid contact angle of PTFE particles is 110 °, and after using roughening, PTFE particle surface droplet contact angle is 150 °, which is a super aerophilic surface.The mode of super aerophobic particle surface modification is: PTFE particles are put into 0.1-0.5 M potassium permanganate solution, stirred at room temperature for 1-2 hour and carried out oxidation treatment, to introduce hydroxyl groups. Subsequently, the particles are filtered and rinsed with deionized water, and then dried to constant weight in a vacuum drying oven. Next, an acrylic acid solution is prepared in a beaker, 1-2% azobisisobutyronitrile is added as an initiator, the activated PTFE particles are added to the solution, and heated to 60-70°C under an inert atmosphere, and stirred for 2-4 hours to carry out graft polymerization. After the reaction is completed, the particles are filtered and washed with ethanol or acetone to remove unreacted monomers and initiators, and then rinsed with deionized water. Finally, the modified particles are dried in a vacuum drying oven to obtain super-aerobic PTFE particles, and the super-aerobic PTFE particle droplet contact angle is 30°.

[0054] After processing the raw materials, filling and assembling in the above manner, a gas-liquid separator based on gradient filling of super-aerophilic and super-aerophobic particles is obtained, such as Figure 1 As shown, the device of the present invention is connected to the electrolytic water electrolysis cell system (not shown in the figure) through the gas-liquid inlet 1 and the liquid outlet 2 to achieve normal operation. The gas-liquid mixture enters the gas-liquid chamber 5 through the gas-liquid inlet 1. First, the mixture passes through the super-aerophilic support mesh 4 and collides with the super-aerophobic large particle 93 on the leftmost side of the large particle filling chamber 10. This collision process causes the fluid to be diverted and the direction of movement to change, thereby ensuring uniform distribution of the fluid. Figure 2 As shown in the left figure, when the gas-liquid fluid collides with the super-aerophobic particles, the gas-liquid mixture realizes the redistribution of direction and flow (the effect of super-aerophobic particles), which has little effect on bubbles. The super-aerophilic corrugated baffle 8 inside the filling chamber also changes the flow direction of the gas-liquid mixture, increasing the probability of collision between the gas-liquid mixture and particulate matter. The redistributed gas-liquid mixture continues to collide with the super-aerophilic large particles 91 and super-aerophobic large particles 93 in the large particle filling chamber 10. Figure 2As shown in the figure on the right, when the gas-liquid mixture collides with the super-aerophilic large particles 91, the bubbles are adhered to the particles, achieving bubble capture. The bubbles on the surface of the particles will collide and fuse on their surface to form larger bubbles (super-aerophilic particle effect). However, since the super-aerophilic large particles can only adhere to bubbles that collide directly, some bubbles are still mixed with the solution. Subsequently, the bubble mixture enters the small particle filling chamber 11 and interacts with the super-aerophilic small particles 92 therein. The bubbles are adhered to the small particles and aggregated into larger bubbles. These large bubbles are easily carried out by the fluid due to their large frontal area. In the bubble floating chamber 6, the large bubbles float to the top of the separator, and after passing through the tertiary gas capture chamber 7, the bubble removal effect is further improved, and the bubbles in the gas-liquid mixture are completely separated. The gas is discharged through the gas outlet, while the liquid passes through the liquid channel constructed by the super-aerophobic particles and passes through the gas capture chamber 7 smoothly and quickly.

[0055] In the present invention, gradient particle packing plays a key role in the gas-liquid separation process. Specifically, a large particle packing chamber 10 is located on the left side of the gas capture chamber 7, and a small particle packing chamber 11 is located on the right side. The large particles in the large particle packing chamber 10 are primarily used to redistribute the liquid and adhere to some bubbles, ensuring that the gas-liquid mixture is evenly distributed and effectively transferred to the small particle packing chamber 11. The small particle packing chamber 11 ensures that bubbles in the gas-liquid mixture are quickly captured.

[0056] In addition, the separation effect is further optimized by using a mixed filling of superaerophilic and superaerophobic particles. Figure 3 As shown in the left figure, if only super-aerophobic large particles 93 are used, although the gas-liquid mixture can flow rapidly along the bubble flow trajectory 13, the bubbles cannot be adhered and separated by the particles, as shown in FIG. Figure 2 As shown in the left figure. If the super-aerophilic large particles 91 are completely filled, although the bubbles in the gas-liquid mixture can be quickly adhered (such as Figure 2 right), but the particles may be connected by gas bridging14 (e.g. Figure 3 By mixing superaerophilic and superaerophobic particles, not only is the smooth flow of the gas-liquid mixture ensured, but also the bubbles are quickly attached and separated by the superaerophilic particles. Figure 3 As shown in the figure on the right. Finally, Figure 4As shown, in a conventional gas-liquid separator, no particles are filled inside the separator, and the bubbles in the gas-liquid separator will float up under the action of gravity to achieve gas-liquid separation. Since it is a passive gas-liquid separation, the separation effect is not good. And in order to ensure a certain separation effect, the gas-liquid flow rate is set to be relatively small (excessive flow rate will cause the gas in the gas-liquid mixture to not have time to float up and be taken back to the electrolytic cell). The gradient-filled super-philic / super-aerosol-repellent particles induce the forced and rapid merging of bubbles in the gas-liquid separator through gradient pore size and gradient wetting properties to achieve rapid gas-liquid separation. Therefore, the gas-liquid mixture stays in the gas-liquid separator for a short time and the separation speed is fast, achieving the highest gas-liquid separation efficiency and the maximum flow rate. From Figure 4 It can be seen that the maximum flow rate in the conventional gas-liquid separator is about 80 L / min, while the maximum flow rate of the gradient-filled superphilic / superaerophobic particles in the gas-liquid separator of this embodiment is about 140 L / min, and the flow rate of the gas-liquid mixture is increased to 175% of the original.
