Description

Technical Field

[0001] This application relates to the field of hydrogen production technology, and more particularly to a two-phase separator in a hydrogen production system. Background Technology

[0002] In electrolytic hydrogen production systems, the hydrogen separator plays a crucial role, effectively separating the hydrogen produced during electrolysis from the electrolyte to ensure hydrogen purity and efficient subsequent utilization. The hydrogen separator is typically located downstream of the electrolyzer, receiving the mixture of hydrogen and electrolyte from the cell. Inside the electrolyzer, water molecules are decomposed into hydrogen and oxygen under the influence of direct current. These two gases, along with the electrolyte, flow out of the cell and into the hydrogen separator. Inside the separator, the mixture first passes through a series of carefully designed channels or structures that utilize gravity and fluid dynamics to naturally separate the gas and liquid during flow. Specifically, because hydrogen's density is much lower than that of the electrolyte, it rises and accumulates at the top of the separator under gravity, while the electrolyte sinks to the bottom. Furthermore, to further improve separation efficiency, the hydrogen separator may also be equipped with specialized washing and cooling devices. These devices use spraying or immersion to wash and cool rising hydrogen gas with clean water or coolant, removing any electrolyte particles and heat it may be carrying. The washed hydrogen is purer, and its temperature is effectively controlled, providing better conditions for subsequent processing and utilization. The washed and cooled hydrogen is then collected through the outlet pipe at the top of the separator and transported to hydrogen storage facilities or used directly in various industrial applications. The electrolyte at the bottom of the separator is then recycled back to the electrolyzer via a circulation pump, achieving electrolyte recycling.

[0003] In existing hydrogen production systems, traditional separation devices are static separation units, which occupy a large area, have low separation efficiency, and rely solely on gravity for gas-liquid separation. The separation effect depends on the length of time the separation has been static and the temperature and pressure environment. Therefore, a more efficient separation device is needed to solve these problems. Summary of the Invention

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0027] like Figure 1 The diagram shown is a schematic of the architecture of a two-phase separator in a hydrogen production system provided in an embodiment of this application, including the following components.

[0028] Ejector device 1, inner cavity 2, and gas guiding device 3.

[0029] The ejector device 1 is used to eject the electrolyte into the stirring and separation zone 6 of the inner cavity 2 in a specified direction, so that the gas-liquid mixture in the stirring and separation zone 6 tumbles and accelerates the precipitation of hydrogen bubbles in the gas-liquid mixture, which includes electrolyte and hydrogen bubbles.

[0030] It should be noted that the ejector device 1 ejects the electrolyte into the stirring and separation zone 6 of the inner cavity 2 in a specified direction, causing the gas-liquid mixture in the stirring and separation zone 6 to tumble. The gas-liquid mixture in the stirring and separation zone 6 can exhibit a boiling state. The tumbling of the gas-liquid mixture can be regarded as the gas-liquid mixture being in a state of violent motion, which can accelerate the precipitation and bursting of hydrogen bubbles in the gas-liquid mixture, so that hydrogen can be separated from the gas-liquid mixture more quickly, effectively improving the hydrogen separation efficiency.

[0031] In some examples, the hydrogen bubbles include both bubbles and foams, and when the hydrogen bubbles burst, they produce hydrogen gas and a target liquid, which may include an electrolyte and / or water. In a possible implementation, the electrolyte may be an alkaline solution.

[0032] Optionally, the ejector device 1 includes an ejector tube 4, which is located in the stirring and separation zone 6. The ejector tube 4 is provided with a plurality of ejector holes 5, and the ejection direction of the plurality of ejector holes 5 is facing the stirring and separation zone 6. The ejector holes 5 are used to spray the electrolyte in the ejector tube 4 in a specified direction so that the electrolyte enters the stirring and separation zone 6 from the ejector tube 4 in a foamy form.

[0033] It is understandable that the electrolyte is first introduced into the stirring and separation zone 6 through the ejector device 1. This is because the electrolyte enters the inner cavity 2 in a foamy state from the ejector tube 4, which is a sudden release process. The foam carrying hydrogen gas is sprayed into the stirring and separation zone 6 in a designated direction by the ejector hole 5 on the ejector tube 4. This causes the gas-liquid mixture in the stirring and separation zone 6 to tumble and boil, which accelerates the precipitation and bursting of hydrogen bubbles, allowing hydrogen gas to be separated more fully from the gas-liquid mixture.

[0034] The inner cavity 2 includes a stirring separation zone 6, a foaming zone 7, a sedimentation separation zone 8, and a vaporization zone 9. The stirring separation zone 6 controls the flow of the gas-liquid mixture into the sedimentation separation zone 8 along a preset path, allowing hydrogen and hydrogen bubbles to be separated from the gas-liquid mixture. The foaming zone 7 promotes the bursting of hydrogen bubbles to obtain the corresponding hydrogen and target liquid. The sedimentation separation zone 8 allows the target liquid and gas-liquid mixture to settle, allowing residual hydrogen to be separated from the target liquid and gas-liquid mixture. The vaporization zone 9 stores the hydrogen from the stirring separation zone 6, the foaming zone 7, and the sedimentation separation zone 8.

[0035] Optionally, the two-phase separator is placed horizontally, with the stirring separation zone 6 and the sedimentation separation zone 8 located in the lower region of the inner cavity 2, and the foaming zone 7 and the vaporization zone 9 located in the upper region of the inner cavity 2, with the foaming zone 7 located above the stirring separation zone 6 and the vaporization zone 9 located above the sedimentation separation zone 8.

[0036] Understandably, since the electrolyte and gas-liquid mixture are liquids, and hydrogen and hydrogen bubbles are gases, when hydrogen and hydrogen bubbles are separated from the gas-liquid mixture in the stirring separation zone 6, they will flow towards the area above the stirring separation zone 6. Therefore, the foaming zone 7 is located above the stirring separation zone 6. Similarly, when hydrogen is separated from the target liquid in the precipitation separation zone 8, it will flow towards the area above the precipitation separation zone 8. Therefore, the vaporization zone 9 is located above the precipitation separation zone 8.

[0037] Optionally, the foam zone 7 includes a baffle plate 10, which is used to block hydrogen bubbles flowing from the foam zone 7 to the vaporization zone 9 and promote the collapse of hydrogen bubbles in the foam zone 7, so that the target liquid obtained after the hydrogen bubbles collapse flows into the precipitation separation zone 8.

[0038] Understandably, the hydrogen bubbles and hydrogen gas generated in the stirring separation zone 6 flow into the foam zone 7, which is adjacent to the vaporization zone 9. To prevent hydrogen bubbles from flowing into the vaporization zone 9, a baffle 10 is installed between the foam zone 7 and the vaporization zone 9. When a hydrogen bubble touches the baffle 10, it is physically collided and breaks to produce the corresponding hydrogen gas and target liquid. The hydrogen gas flows to the vaporization zone 9, and the target liquid flows into the precipitation separation zone 8 due to gravity, thus achieving isolation between the hydrogen bubbles and the hydrogen gas.

[0039] Optionally, the stirring separation zone 6 includes a weir 11, which guides the gas-liquid mixture into the sedimentation separation zone 8 along a preset path and promotes the rupture of hydrogen bubbles within the stirring separation zone 6.

[0040] It is understandable that the layout of the cofferdam 11 can form a preset path. When the gas-liquid mixture flows into the sedimentation separation zone 8 according to the preset path, the gas-liquid mixture is in a flowing state, thereby accelerating the separation efficiency of hydrogen and hydrogen bubbles from the gas-liquid mixture, and also accelerating the efficiency of hydrogen bubble bursting.

[0041] In a possible implementation, the layout of the cofferdam 11 can be a vortex, thereby causing the gas-liquid mixture flowing within the preset path to exhibit a stirring and separation effect. The so-called stirring and separation can be understood as stirring the gas-liquid mixture to improve the separation efficiency of hydrogen and hydrogen bubbles.

[0042] Optionally, the stirring separation zone 6 also includes a drain port 12, which allows liquid in the stirring separation zone 6 to flow out of the two-phase separator when the drain port 12 is opened.

[0043] In some examples, the shape, size, and installation location of the drain outlet 12 can be set by technicians according to the actual situation.

[0044] Understandably, after the hydrogen production system finishes its hydrogen production task, the liquid in the stirring separation zone 6 can be allowed to flow out of the two-phase separator by opening the drain port 12, ensuring that there are no impurities in the stirring separation zone 6 when the next hydrogen production task is performed.

[0045] It should be noted that the hydrogen bubbles in the stirring separation zone 6 flow into the foam zone 7. Through physical collision with the baffle plate 10 in the foam zone 7, the hydrogen bubbles burst and the hydrogen gas generated flows into the vaporization zone 9. The target liquid generated by the bursting of hydrogen bubbles flows into the precipitation separation zone 8, so that the precipitation separation zone 8 stores a solution composed of the target liquid and the gas-liquid mixture. This solution (which can be regarded as an electrolyte) undergoes secondary separation in the precipitation separation zone 8. Through the settling process, the residual hydrogen gas in the solution is separated out.

[0046] Optionally, the precipitation separation zone 8 also includes a drain port 13. When the switch of the drain port 13 is opened, the liquid in the precipitation separation zone 8 flows back from the drain port 13 to the electrolyzer of the hydrogen production system.

[0047] In some examples, the architecture of a hydrogen production system (such as an electrolysis hydrogen production system) can be found in [reference needed]. Figure 2 As shown, the hydrogen separator (equivalent to the two-phase separator shown in this application) is an indispensable part of the electrolytic hydrogen production system. Its main function is to effectively separate the hydrogen and oxygen produced after electrolysis. The hydrogen separator separates the gas from the electrolyte through a series of processes to ensure the purity and quality of the hydrogen. Specifically, when the drain port 13 is opened, the liquid in the precipitation separation zone 8 flows back to the circulation pump of the hydrogen production system from the drain port 13. The circulation pump then merges the liquid in the oxygen separator and the liquid in the precipitation separation zone 8 back into the electrolyzer to achieve electrolyte recycling.

[0048] The gas guiding device 3 is used to guide the hydrogen gas in the vaporization zone 9 to the outside of the two-phase separator.

[0049] Optionally, the gas guiding device 3 includes a gas collecting screen 14, an outlet pipe 15, and a return pipe 16. The gas collecting screen 14 is located in the vaporization zone 9 and is used to collect hydrogen gas in the vaporization zone 9. The outlet pipe 15 is used to lead the hydrogen gas collected by the gas collecting screen 14 out of the two-phase separator. The return pipe 16 is used to guide the water in the gas collecting screen 14 to the sedimentation separation zone 8.

[0050] Optionally, the outlet pipe 15 includes a defoamer 17, which is used to intercept moisture carried in the hydrogen gas so that the intercepted moisture flows back into the gas collecting screen 14.

[0051] In some examples, the type of defoamer 17 includes, but is not limited to, a dehydrating mesh. Generally, when the outlet pipe 15 leads hydrogen gas carrying moisture out of the two-phase separator, the built-in dehydrating mesh can be used to intercept the moisture, so that the intercepted moisture is stored in the gas collecting screen 14 and flows into the sedimentation separation zone 8 through the return pipe 16.

[0052] Understandably, the defoaming effect provided by the defoamer 17 ensures that pure and dry hydrogen gas is drawn out from the outlet pipe 15 to the outside.

[0053] Obviously, the two-phase separator optimizes the overall structure of the hydrogen separator, improves the separation efficiency, and makes the most of the physical properties of gas and liquid. The stirring effect of the stirring separation zone 6 causes hydrogen to be released, and then the combined action of the baffle plate 10 and the weir 11 breaks most of the hydrogen bubbles, separating the hydrogen from the electrolyte. The excess water carried in the hydrogen is completely drained through the defoamer 17 on the outlet pipe 15, and the collected water droplets flow back to the sedimentation separation zone 8 through the return pipe 16, so that the electrolyte can be recycled.

[0054] Optionally, the gas collecting screen 14 includes a plurality of gas collecting holes 18, all of which face directly upward and are located in the top region of the vaporization zone 9, so that the gas collecting screen 14 collects hydrogen in the top region.

[0055] Understandably, hydrogen gas and hydrogen bubbles may coexist in vaporization zone 9. The hydrogen bubbles are heavier than the hydrogen gas, so the hydrogen gas is located in the top region of vaporization zone 9, while the hydrogen bubbles may accumulate in other regions below the top region. Since the gas collecting holes 18 of the gas collecting screen 14 face directly upward and are located in the top region of vaporization zone 9, only the hydrogen gas in the top region can be drawn into the gas collecting holes 18, while the slightly heavier hydrogen bubbles will settle into the precipitation separation zone 8 located below vaporization zone 9.

[0056] Optional, see Figure 3 The improved architecture shown also includes a level sensor 19 in the two-phase separation tank. The level sensor 19 is used to monitor the level of the gas-liquid mixture in the stirring separation zone 6. When the level meets a preset threshold, the ejector device 1 stops ejecting electrolyte into the stirring separation zone 6.

[0057] Understandably, by using the liquid level monitoring provided by the liquid level sensor 19, the automatic injection of the ejector device 1 can be achieved, ensuring that the volume of the gas-liquid mixture in the stirring separation zone 6 is maintained within the calibrated range.

[0058] Based on the architecture of the two-phase separator described above, the problems of large footprint, limited separation methods, and low efficiency of traditional separation devices are solved. The two-phase separator replaces traditional static separation with a combination of stirring and static separation, fully utilizing the effects of stirring and gravity precipitation to effectively separate the gas (hydrogen) and liquid (electrolyte). Furthermore, the addition of a weir and baffles ensures that the stirred electrolyte flows along a predetermined path into the sedimentation separation zone for further separation of residual hydrogen. In addition, the separation efficiency is greatly increased within the same volume, as the combined use of stirring and static separation methods ensures that hydrogen in the electrolyte is fully separated along the predetermined path. The two-phase separator does not rely on electronic equipment for monitoring; only a liquid level sensor is needed, making it more efficient than traditional separation devices.

Certain features described in the context of individual embodiments may also be implemented in combination in a single embodiment. Conversely, various features described in the context of a single embodiment may also be implemented individually or in any suitable sub-combination in multiple embodiments.

Those skilled in the art should understand that the scope of disclosure in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described concept.
