The core of hydrogen production equipment is the hydrogen production device. Since hydrogen production and storage is a complete system, if the hydrogen production device is put into production line without monitoring in actual application, hydrogen may leak during the hydrogen production process and mix into the electrolyzed water, causing damage to the subsequent hydrogen production system pipelines. In severe cases, it may cause the problem of low purity of hydrogen production.

[0003] For this reason, it is necessary to simulate the hydrogen production process and conduct a hydrogen production test on the hydrogen production device before it is put into use to determine the structural stability of the hydrogen production device, so that the hydrogen production device after the test can be put into use in the production line.

[0004] This testing process is designed to verify the effectiveness of the hydrogen production reaction mechanism and the performance of the equipment under specific working conditions. However, existing testing methods often have problems such as complex operation, long testing cycle, and high cost, which make it difficult to meet the needs of fast and accurate testing.

[0005] In the design and application of portable water electrolysis hydrogen production test equipment, a key technical issue is the rapid verification and optimization of the gas-liquid separation effect. Since hydrogen and oxygen will be produced in the process of water electrolysis hydrogen production, accompanied by water electrolysis and electrolyte circulation, gas-liquid separation is an important link to ensure hydrogen production efficiency and equipment safety.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] This is the first embodiment of the present invention, which provides a portable water electrolysis hydrogen production testing device.

[0028] Specifically, refer to Figure 1 and Figure 2 , including a main body assembly 100; The electrolytic cell 201 and the gas-liquid separator 202 are arranged on the inner wall of the main assembly 100. The gas-liquid separator 202 is in communication with the electrolytic cell 201. A plugging component and a drainage component are arranged inside the gas-liquid separator 202. The plugging component is used to isolate the gas pressure inside the gas-liquid separator 202. The drainage component is located at the end of the gas-liquid separator 202 and is used to drain the accumulated water inside the gas-liquid separator 202. When the electrolytic cell 201 electrolyzes gas, the gas enters the gas-liquid separator 202 and increases the gas pressure inside the gas-liquid separator 202. The sealing component is used to isolate the gas pressure inside the gas-liquid separator 202. The drainage component is moved upward as a whole under the influence of the gas pressure to block the drainage port to prevent the gas generated by the electrolytic cell 201 from overflowing. When the accumulated water at the end of the gas-liquid separator 202 accumulates to a certain level, the sealing component is pushed open by the drainage component, and the accumulated water inside the gas-liquid separator 202 is discharged while the drainage component is reset.

[0029] Among them, pure water is stored in a water tank, and the water level is controlled by a water replenishment solenoid valve. After the pure water reaches the working temperature through the water supply pump group and the pure water cooling component, it enters the electrolytic cell 201 through the water supply channel. There are two electrodes in the electrolytic cell 201, the cathode and the anode. When direct current is passed, water undergoes an electrochemical reaction on the surface of the electrodes. At the anode, water molecules lose electrons to generate oxygen and hydrogen ions, and at the cathode, hydrogen ions gain electrons to generate hydrogen, thereby realizing the process of electrolyzing water to produce hydrogen. The hydrogen produced after electrolysis enters the gas-liquid separator 202 for gas-liquid separation to remove moisture from the gas.

[0030] The separated hydrogen enters the dryer and is further dehumidified by the adsorbent to meet the humidity requirements of the hydrogen. The dried hydrogen is measured for hydrogen production rate by a high-pressure mass flow meter, and the water content in the hydrogen is detected to evaluate the purity of the hydrogen. Qualified hydrogen is collected by a hydrogen collecting pipe and can be discharged through a hydrogen receiving pipe or stored in a hydrogen bag.

[0031] After the hydrogen enters the gas-liquid separator 202, the air pressure inside the gas-liquid separator 202 increases, and the internal sealing components do not move. Under the influence of the increased air pressure, the drainage component at the bottom moves upward and blocks the bottom drainage port at the same time. At this time, the water vapor inside the gas-liquid separator 202 condenses into liquid and slides to the bottom of the gas-liquid separator 202. Since the bottom drainage port is blocked, the accumulated water cannot be discharged to the outside temporarily and slowly gathers. As the accumulated water increases, the water level rises. Affected by the buoyancy of the water level, the drainage component moves up with the water level and touches the sealing component to open the opening of the sealing component. At this time, the air pressure inside the gas-liquid separator 202 enters the drainage component through the sealing component, causing the drainage component to move down and reset. At this time, the lower drainage port is opened, and the accumulated water inside the gas-liquid separator 202 is discharged to the outside. After the drainage component moves down and resets, the upper sealing component resets to continue to seal the gas to prevent the generated hydrogen from leaking.

[0032] Example 2

[0033] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0034] Specifically, refer to Figure 2 , Figure 5 and Figure 6 The gas-liquid separator 202 is internally divided into an air chamber and a liquid chamber. The air chamber is located at the end of the liquid chamber and is used to separate water vapor in the gas. The liquid chamber is located at the end of the gas-liquid separator 202 and is used to accumulate liquid condensed from water vapor in the gas and discharge it when the liquid accumulates to a water level threshold.

[0035] A mounting shell 205 is provided at the end of the gas-liquid separator 202, and a mounting head 2051 is provided at the end of the mounting shell 205.

The end of the sealing head 206 is attached to the inner wall of the mounting head 2051 to form a sealed cavity 2063. The circular hole 2062 is connected with the sealed cavity 2063 to form an airway for air flow inside the cavity 2061 and the sealed cavity 2063.

[0036] The mounting shell 205 is fixed to the bottom of the gas-liquid separator 202. Figure 6 As shown, the sealing component is inside the mounting head 2051 at the top of the mounting shell 205, and a sealed cavity 2063 is formed between the outer wall of the sealing head 206 and the inner wall of the mounting head 2051. The sealing head 206 and the mounting head 2051 fit tightly, and external gas cannot enter the interior of the mounting shell 205 through the mounting head 2051.

[0037] Preferably, a connecting channel 2064 is also opened on the outer wall of the plugging head 206 and the connecting channel 2064 is connected to the sealing cavity 2063 . The connecting channel 2064 is connected to the cavity 2061 through the sealing cavity 2063 , and the air inside the cavity 2061 enters the connecting channel 2064 through the sealing cavity 2063 .

[0038] Similarly, the connecting channel 2064 is connected to the sealed cavity 2063. Since the cavity 2061 is connected to the sealed cavity 2063, the air in the cavity 2061 enters the sealed cavity 2063 through the circular hole 2062 and then enters the interior of the connecting channel 2064 and enters the other end of the sealing head 206.

[0039] A sealing rod 2066 is movably provided on the inner wall of the sealing head 206, a sealing block 2067 is provided at the end of the sealing rod 2066 and the sealing block 2067 is located at the end of the cavity 2061, the sealing block 2067 is used to isolate the gas inside the cavity 2061, a movable cavity 2065 is opened at the end of the sealing head 206 facing away from the cavity 2061 and the end of the sealing rod 2066 extends into the movable cavity 2065, a blocking block 2068 is provided at the end of the sealing rod 2066 and a first elastic member 2069 is provided at the end of the blocking block 2068, the first elastic member 2069 is sleeved on the end of the sealing rod 2066 to push the sealing rod 2066 and make the blocking block 2067 close to the cavity 2061.

[0040] Among them, Figure 6 As shown, the blocking rod 2066 is movably installed inside the blocking head 206, and the blocking block 2067 on the top of the blocking rod 2066 is tightly attached to the top of the cavity 2061, and the blocking block 2067 is used to isolate the outside air from entering the cavity 2061. The other end of the blocking rod 2066 is inside the movable cavity 2065 at the bottom of the blocking head 206, and a blocking block 2068 is provided at the end. The first elastic member 2069 is sleeved on the outside of the blocking rod 2066 and the first elastic member 2069 is between the blocking block 2068 and the inner wall of the movable cavity 2065. The blocking rod 2066 is pushed downward inside the blocking head 206 by the first elastic member 2069, and the blocking block 2067 is tightly attached to the top of the cavity 2061 without being affected by other factors, so that the cavity 2061 is isolated from the outside.

[0041] Reference Figure 5 , Figure 7 and Figure 8The drainage component is located at the end of the mounting shell 205 and includes a movable sleeve 207, a straight rod 2071 is fixed to the axis of the movable sleeve 207, a hollow block 2072 is provided at the end of the straight rod 2071 and an array of openings 2073 are provided on the end face of the hollow block 2072, the straight rod 2071 is also sleeved with a second elastic member 2074, the other end of the second elastic member 2074 is in contact with the plugging head 206, and the second elastic member 2074 is used to push the plugging head 206 to make it engage inside the mounting head 2051.

[0042] The movable sleeve 207 is installed at the bottom of the installation shell 205, and the straight rod 2071 is fixed inside the movable sleeve 207 and is opposite to the blocking rod 2066 inside the blocking head 206. Initially, there is a distance between the two and they are not in contact.

[0043] The hollow block 2072 is fixed at the bottom of the straight rod 2071 and installed in the middle of the movable sleeve 207. An opening 2073 is provided on the surface of the hollow block 2072. At the same time, a second elastic member 2074 sleeved on the surface of the straight rod 2071 is located in the middle of the plugging head 206 and the movable sleeve 207, pushing the plugging head 206 upward inside the mounting head 2051.

[0044] like Figure 5 As shown, the movable sleeve 207 moves inside the mounting shell 205, the top outer wall of the movable sleeve 207 is in close contact with the inner wall of the mounting shell 205, the sealing head 206 seals the inner wall of the mounting head 2051, and the gas outside the mounting shell 205 can only pass through the cavity 2061 at the top of the sealing head 206, and enter the interior of the mounting shell 205 through the circular hole 2062 and the connecting channel 2064.

[0045] Reference Figure 7 A movable head 2075 is also provided at the end of the movable sleeve 207. A limit block 2076 is provided at the end of the movable head 2075 for limiting the upward movement distance of the movable sleeve 207. A through groove 2077 is also penetrated through the inner wall of the movable head 2075 and the through groove 2077 is connected to the inner wall of the movable sleeve 207. The through groove 2077 is used for pressure relief.

[0046] Among them, a through groove 2077 is opened inside the movable head 2075, and the through groove 2077 is connected with the interior of the movable sleeve 207. When the sealing rod 2066 inside the sealing head 206 moves to expose the cavity 2061 and connect it to the outside, the outside air enters the interior of the mounting shell 205 through the cavity 2061 and is discharged to the outside through the through groove 2077 at the bottom of the movable sleeve 207, so that the air pressure inside the mounting shell 205 is equal to the air pressure inside the gas-liquid separator 202.

[0047] Better, refer to Figure 2 and Figure 8A slot 2052 is provided at the end of the mounting shell 205 for fixing it at the end of the gas-liquid separator 202. A floating block 208 is also sleeved on the outer wall of the mounting shell 205. A connecting rod 2081 is provided on the inner wall of the floating block 208, and the connecting rod 2081 slides on the inner wall of a movable groove 2053 provided on the surface of the mounting shell 205. An inner ring 2082 is fixed to the other end of the connecting rod 2081, and the inner ring 2082 is sleeved on the end of the movable sleeve 207 for driving the movable sleeve 207 to move upward. A spacer 2054 is also provided on the inner wall of the mounting shell 205, and the spacer 2054 is located at the end of the limit block 2076 for limiting the movable sleeve 207.

[0048] Among them, the card slot 2052 at the bottom of the mounting shell 205 is connected to the outer wall of the gas-liquid separator 202, and the mounting shell 205 is fixed to the bottom of the gas-liquid separator 202. The floating block 208 is outside the mounting shell 205. When the accumulated water inside the gas-liquid separator 202 accumulates, the floating block 208 rises due to the buoyancy. The floating block 208 is connected to the inner ring 2082 inside the mounting shell 205 through a connecting rod 2081. The inner ring 2082 is below the top of the movable sleeve 207. When the floating block 208 moves up, the inner ring 2082 moves upward together, driving the movable sleeve 207 to rise with the water level. The spacer 2054 at the bottom of the mounting shell 205 is located above the limit block 2076 at the end of the movable head 2075, and the limit block 2076 is limited. The upward movement distance of the movable sleeve 207 is limited by the spacer 2054.

[0049] In summary, when in use, the electrolytic cell 201 is screwed into the interior of the device and connected to the gas-liquid separator 202 to form a whole, which is used to perform a simulation test on the electrolytic hydrogen production body that constitutes the whole, so as to determine the electrolytic hydrogen production and the gas-liquid separation effect after hydrogen production, and the overall structure can be quickly disassembled to facilitate the simulation test of different electrolytic hydrogen production bodies before installation on the production line. When the electrolytic cell 201 starts to electrolyze water to produce hydrogen, the hydrogen enters the interior of the gas-liquid separator 202 to separate the gas from the water vapor. At this time, the air pressure inside the gas-liquid separator 202 increases. Since the sealing block 2067 is tightly attached to the top of the cavity 2061, the air pressure cannot enter the interior of the mounting shell 205 and cannot be discharged to the outside. As the internal air pressure increases, the high pressure enters through the movable groove 2053 on the surface of the mounting shell 205, and the movable sleeve 207 is inserted into the mounting shell 205. When the movable sleeve 207 is lifted upward, the sealing ring at the bottom further blocks the drain outlet below the gas-liquid separator 202. At the same time, the internal air pressure is still retained in the gas-liquid separator 202. As the hydrogen and water vapor above are separated, the water vapor condenses into water and accumulates at the bottom of the gas-liquid separator 202. The water level gradually rises, and at the same time, the floating block 208 outside the mounting shell 205 is driven to move upward. The inner ring 2082 inside rises synchronously with the floating block 208 and pushes the movable sleeve 207 upward.

[0050] The movable sleeve 207 is limited in the upward distance due to air pressure. When the water level rises, it is pushed by the inner ring 2082 to further rise inside the mounting shell 205, and the middle straight rod 2071 touches the blocking rod 2066 in the middle of the blocking head 206, pushing it upward, so that a gap appears between the blocking block 2067 and the cavity 2061. At this time, the internal high-pressure gas enters the interior of the cavity 2061 through the gap, and the distance between the blocking block 2067 and the cavity 2061 becomes larger. The external high-pressure gas passes through the circular hole on the surface of the cavity 2061. 2062 enters into the sealing cavity 2063 on the side, and enters into the movable cavity 2065 below the plugging head 206 through the connecting channel 2064, and finally enters into the interior of the mounting shell 205. The movable sleeve 207 moves downward under the action of the high-pressure gas and the second elastic member 2074, and the internal high-pressure gas is finally discharged to the outside through the through groove 2077 at the bottom of the movable head 2075. As the movable sleeve 207 moves downward, a gap appears at the drain outlet at the bottom of the mounting shell 205, and the accumulated water inside the gas-liquid separator 202 is discharged outward.

[0051] When the movable sleeve 207 moves downward, the straight rod 2071 loses contact with the sealing rod 2066. Under the action of the first elastic member 2069, the sealing rod 2066 presses the sealing block 2067 against the cavity 2061 again to isolate the internal hydrogen and prevent leakage. At the same time, the accumulated water at the bottom stops being discharged after a part of it is discharged, and a part of it is accumulated at the bottom, repeating the previous process. When the electrolytic cell 201 stops, the gas-water separation work inside the gas-liquid separator 202 stops, and the movable sleeve 207 falls to the bottom. At the same time, the accumulated water inside is discharged.

[0052] Example 3 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0053] Specifically, refer to Figure 2 and Figure 3 An air inlet 2021 is provided on the outer wall of the gas-liquid separator 202 and a guide groove 2022 is opened on the inner wall of the air inlet 2021. The guide groove 2022 is connected to an air cavity 2023 opened on the inner wall of the gas-liquid separator 202. A guide port 2024 is provided at the end of the air cavity 2023 and an air outlet 2025 is opened at the end of the guide port 2024.

[0054] The guide groove 2022 is a downwardly inclined groove and is connected to the air inlet 2021. After the hydrogen generated by the electrolytic cell 201 enters the guide groove 2022 through the air inlet 2021, it is guided by the downwardly inclined guide groove 2022, and the entire hydrogen moves obliquely downward.

[0055] The guide port 2024 is on the side of the guide groove 2022 but the two are not connected. The hydrogen separated from the water vapor enters the gas outlet 2025 above through the guide port 2024 and is discharged to the outside of the gas-liquid separator 202 .

[0056] like Figure 4 As shown, preferably, a swirl shell 203 is provided on the inner wall of the air cavity 2023, and an array of inclined plates 2031 are provided on the outer wall of the swirl shell 203 to guide and accelerate the rotation speed of the gas. An arc top 2032 is provided at the end of the inclined plate 2031 to guide the gas to flow outward. The inner wall of the air cavity 2023 is also provided with a slope 2033, which is used to fix the swirl shell 203 and is also used to separate water vapor and guide gas.

[0057] Among them, the swirl shell 203 is fixed inside the air cavity 2023. After the hydrogen is guided by the inclined groove of the guide groove 2022, it tilts downward and enters the inside of the swirl shell 203 through the inclined plate 2031 on the surface of the swirl shell 203. In this process, the rotation speed of the hydrogen airflow becomes faster and moves downward. When the airflow passes through the slope 2033, the closer the bottom of the slope 2033 is, the faster the airflow rotates, and the water vapor inside is thrown out, condensed on the surface of the slope 2033 and falls along the slope 2033. The gas that throws out the water vapor rises and enters the outlet 2025 through the guide port 2024.

[0058] A circular plate 204 is also provided on the inner wall of the air cavity 2023. The circular plate 204 is located at the end of the blocking component for protection. At the same time, an array of hydrophobic holes 2041 are provided on the outer wall of the circular plate 204 for the passage of liquid.

[0059] Among them, the circular plate 204 is installed in the air cavity 2023, located above the mounting head 2051. When water drops above the slope 2033 fall, they are blocked by the circular plate 204 and will not drip directly into the mounting head 2051, but will slide along the hydrophobic holes 2041 on the side of the circular plate 204 into the bottom of the gas-liquid separator 202.

[0060] Better, refer to Fig. 9 A clamping component 300 is provided at the end of the gas-liquid separator 202, and the other end of the clamping component 300 is connected to the water pipeline. The clamping component 300 is used for quick connection between the gas-liquid separator 202 and the water pipeline. At the same time, a hydrogen detector is provided on the inner wall of the water pipeline to detect hydrogen on the inner wall of the water pipeline.

[0061] Among them, the fixed head 301 is fixed at the bottom of the mounting shell 205, located below the spacer block 2054, and a connecting head 303 is arranged on the outside of the fixed head 301, and the two are connected and fixed by threaded cooperation. When the abutment block 304 inside the connecting head 303 is connected, the vertical rod 3041 on the surface touches the internal connection block 302 inside the fixed head 301 and presses the third elastic member 305 downward, thereby opening the channel in the locking component 300, and the accumulated water inside the gas-liquid separator 202 enters the water supply pipe below through the locking component 300 when discharged outward, and is detected by the hydrogen detector inside the water supply pipe to detect whether hydrogen is discharged along with the accumulated water when the gas-liquid separator 202 is drained outward.

[0062] When the gas-liquid separator 202 is removed, the connector 303 is separated from the fixed head 301, and the third elastic member 305 pushes the abutment block 304 upward to abut against the end of the connector 303 to prevent foreign debris from falling into the water delivery pipe.

[0063] The electrolyzer 201 is integrated with the gas-liquid separator 202 and can be quickly disassembled inside the device. After the test of the hydrogen production device is completed, it can be quickly disassembled from the device, and the tested hydrogen production device can be put into the production line and installed on the next hydrogen production device to be tested for testing.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
