[0002] With the continuous deepening of national energy reform and the continuous updating of energy Internet technology, more and more challenges and opportunities are emerging in the energy field. Hydrogen burns without pollution and has high calorific value. It is an environmentally friendly clean energy with broad prospects for replacing petroleum fuels. Water, as a renewable energy source with abundant content on the earth, is one of the important raw materials for the production of hydrogen and oxygen. The electrolysis of water to produce hydrogen has the characteristics of efficient reduction power and clean hydrogen evolution, making it a promising method. At present, in the process of hydrogen production by water electrolysis, the generated hydrogen will carry water and the capacity of the hydrogen collection device is small, resulting in intermittent operation of the hydrogen production equipment and low production efficiency. Therefore, it is necessary to effectively treat the hydrogen carrying water.

[0003] The current vertical precision vapor-liquid separator installs a condenser in the separation tank to condense the steam, and then separates the condensed steam into vapor and liquid through a separation screen. However, due to the short residence time of the steam in the separation tank, it is difficult to completely separate the liquid, which affects the vapor-liquid separation effect. Moreover, after the liquid falls to the bottom of the separation tank, it is usually necessary to wait until the bottom of the separation tank is filled with liquid before the liquid can be discharged. Therefore, it is necessary to stop the machine and wait, which wastes time, resulting in inconvenient liquid discharge and poor work efficiency.

[0004] In summary, there is an urgent need to develop a vapor-liquid separation device to meet the needs of water electrolysis hydrogen production process. Utility Model Content

[0024] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0025] Unless otherwise defined, the technical or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which this application belongs. The words "first", "second" and similar words used in the patent application specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0026] like Figure 1 , Figure 2 As shown, the utility model shows a float type gas-liquid separation device, including a separator shell 5 and a drainage device connected to its bottom, and a PLC controller. The separator shell 5 is provided with a separation chamber and a float 7 from top to bottom, wherein the separation wall adopts a multi-layer porous plate 4. The gas passes through the collision of the porous plate 4, condenses and adsorbs on the porous plate and the shell wall, giving the steam sufficient separation time to separate the gas and liquid droplets, so that they will not be taken away by the gas again to form secondary steam. Compared with the prior art, the gas production efficiency is significantly improved.

[0027] In this embodiment, the separator housing 5 is provided with an upper sealing cover plate 3, a separation chamber, a floating ball 7 and a lower sealing pressure plate 9 in sequence from top to bottom.

[0028] Specifically, the separation chamber includes a plurality of porous plates 4 evenly spaced and arranged in parallel from top to bottom from the open end of the separator housing 5, the shape of the porous plates 4 is adapted to the cross section of the separator housing 5, and the middle of the plurality of porous plates 4 is separated by a cavity partition 8 perpendicular to the top surface of the separator housing 5, so that the separation chamber is divided into a left air inlet chamber 13 and a right air outlet chamber 14. An air inlet 1 is provided on the left side of the upper sealing cover plate 3 to connect to the left air inlet chamber 13, and an air outlet 2 is provided on the right side to connect to the right air outlet chamber 14; the upper sealing cover plate 3 is also provided with a mounting seat for a touch sensor 6, and the touch sensor 6 is used to sense the position of a float 7; the float 7 is located at the bottom of the separator housing 5 and rises and falls with the liquid accumulated at the bottom. When the gas enters the separator shell 5 from the air inlet 1, the gas collides with the porous plate 4 and condenses and adsorbs on the porous plate and the shell wall of the separator shell 5. Since there are multiple layers of porous plates 4 from the air inlet 1 to the bottom, the internal space is large, and the gas flows in multiple directions. The more small molecule droplets are separated, the more they flow downward along the multiple layers of porous plates 4, and the flow rate decreases, so that the small molecule droplets have enough time to condense into larger droplets, and will not be taken away by the gas to form secondary steam; due to different specific gravities, the large droplets will fall to the bottom of the separator shell 5, and the separated gas will come out from the porous plate 4 at the bottom of the left air inlet cavity 13 and can then be discharged from the right air outlet cavity 14.

[0029] Furthermore, the separator housing 5 is made of stainless steel 316L, which is corrosion-resistant, rust-proof and durable.

[0030] Furthermore, the porous plate 4 may be a circular plate with small holes evenly distributed thereon. The present application does not limit the shape of the porous plate 4, and the shape may be customized according to specific circumstances.

[0031] Furthermore, the upper sealing cover plate 3 is fixed to the top of the separator housing 5 by using a long threaded rod and a nut. A plurality of threaded grooves are provided on the edge of the open end of the separator housing 5 to correspond to the threaded holes provided on the upper sealing cover plate 3. The long threaded holes penetrate the threaded holes and threaded grooves, and then nuts are used to tighten and lock them, so that the upper sealing cover plate 3 and the separator housing 5 are firmly installed.

[0032] Furthermore, a sealing ring is provided between the upper sealing cover plate 3 and the separator housing 5, and a sealing ring is also provided between the lower sealing pressure plate 9 and the bottom of the separator housing 5. The lower sealing pressure plate 9 is fixed to the bottom of the separator housing 5 by a long threaded rod and a nut.

[0033] Furthermore, the air inlet 1 , the air outlet 2 , and the base of the touch sensor 6 are respectively welded to the upper sealing cover plate 3 .

[0034] Furthermore, the porous plate 4 and the cavity partition 8 are welded together to divide the separation cavity into a left air inlet cavity 13 and a right air outlet cavity 14. When the gas-liquid separation device is installed, the porous plate 4 and the cavity partition 8 are installed as a whole into the separator housing 5, and the installation is convenient and simple.

[0035] Furthermore, the float 7 can be a plastic float or a foam float.

[0036] In this embodiment, the drainage device includes a drainage hose 11 and a liquid solenoid valve 12 connected thereto, and the drainage hose 11 is connected to a water outlet provided on the lower sealing plate 9 .

[0037] In this embodiment, the gas-liquid separation device further includes a PLC controller electrically connected to the liquid solenoid valve 12 and the touch sensor 6 .

[0038] Furthermore, the sensing end of the touch sensor 6 is located below the separation chamber and above the float 7. After the large liquid droplets gather to a certain liquid level at the bottom of the separator shell 5, the float 7 rises and then touches the touch sensor 6. The touch sensor 6 sends a signal to be fed back to the PLC controller. The PLC controller controls the opening of the liquid solenoid valve 12 to drain the accumulated liquid at the bottom of the separator shell 5 to the water tank through the drain hose 11.

[0039] Furthermore, the drainage hose 11 is preferably a PU transparent tube, which is convenient for the staff to observe the discharge of the liquid.

[0040] Furthermore, the bottom end of the separator housing 5 is mounted on a fixed base 10 .

[0041] Furthermore, the air inlet 1 is connected to the air outlet pipe of the water electrolyzer, and the hydrogen containing saturated water generated after the water electrolyzer is powered on enters the separator housing 5 through the air inlet 1 for gas-liquid separation.

[0042] In this embodiment, the installation sequence of the float type gas-liquid separation device is: first install the float 7 and the welded porous plate 4 into the separator housing 5, then install the upper and lower sealing pressure plates 9 and the sealing ring, and then tighten and lock the upper sealing cover plate 3 and the lower sealing pressure plate 9 through long threaded rods and nuts.

[0043] The working principle of the float type gas-liquid separation device of this embodiment is as follows: the hydrogen generated after the water electrolyzer is powered on contains saturated water, and the hydrogen containing water enters the separator housing 5 from the air inlet 1. The gas collides with the porous plate 4 and condenses and adsorbs on the porous plate and the housing wall of the separator housing 5. Since there are multiple layers of porous plates 4 from the air inlet 1 to the bottom, the internal space is large, and the gas flows in multiple directions. The more small molecular droplets are separated, the more they flow downward along the multiple layers of porous plates 4, and the flow rate is reduced, so that the small molecular droplets have enough time to condense into larger droplets, and the gas will not be condensed. As for being taken away by the gas to form secondary steam; due to different specific gravities, large droplets will fall to the bottom of the separator shell 5, and the separated gas will come out from the porous plate 4 at the bottom of the left air inlet cavity 13 and then be discharged from the right air outlet cavity 14; after the large droplets gather to a certain liquid level at the bottom of the separator shell 5, the float 7 rises and then touches the touch sensor 6, and the touch sensor 6 sends a signal to feed back to the PLC controller, and the PLC controller controls the opening of the liquid solenoid valve 12, and the accumulated liquid at the bottom of the separator shell 5 is discharged to the water tank through the drainage hose 11.

[0044] In summary, the technical solution of this application has the following beneficial effects:

[0045] In the utility model, a separation chamber is installed in the gas-liquid separator, and a plurality of layers of porous plates are arranged in the separation chamber. An isolation plate is arranged in the middle of the plurality of layers of porous plates for blocking the gas. The gas collides with the porous plates and is condensed and adsorbed on the porous plates and the shell wall of the separator shell. Since there are a plurality of layers of porous plates from the air inlet to the bottom, the internal space is large, and the gas flows in multiple directions. The more small molecular droplets are separated, the more they flow downward along the plurality of layers of porous plates, and the flow rate is reduced, so that the small molecular droplets have enough time to condense into larger droplets. The droplets fall into the lower part of the inner cavity of the separator shell to separate the gas. The gas will enter the upper part of the gas-liquid separator through the right side gas outlet cavity of the gas-liquid separator for output, thereby realizing the separation of gas and liquid and significantly improving the gas production efficiency.
