[0002] High-purity hydrogen plays an indispensable role in fields such as semiconductors, optical fiber manufacturing, and scientific research. Currently, there are various devices on the market that produce high-purity hydrogen through water electrolysis. These devices typically integrate the hydrogen production unit, purification unit, and electrical control unit into a single cabinet to achieve compactness and integration.

[0003] However, existing integrated high-purity hydrogen equipment often has some inherent layout defects. On the one hand, the electrical control section and the core hydrogen production components often share the same space. The heat generated during electrolysis and potential gas leaks can easily affect precision circuits, posing safety hazards and potentially shortening the lifespan of electrical components. On the other hand, the layout of the various functional modules inside the equipment is often scattered, with complex piping connections. This not only increases the difficulty of equipment assembly and maintenance but may also affect purification efficiency and the final hydrogen output quality due to obstructed gas flow paths. Therefore, there is an urgent need for an integrated equipment solution with a more rational layout and higher safety. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1 to 7 As shown, this utility model discloses an integrated hydrogen production and purification device, including a cabinet 10, an electrical control mechanism 20, and a hydrogen production mechanism. The cabinet 10 is internally divided by vertically arranged partitions into a first operating chamber 11 and a second operating chamber 12, which are arranged side-by-side and independent of each other. The electrical control mechanism 20 is located in the first operating chamber 11 and is used to provide power and implement control. The hydrogen production mechanism is centrally located in the second operating chamber 12 and is used to complete the entire process of producing high-purity hydrogen through water electrolysis.

[0025] The electrical control mechanism 20 includes a power supply assembly 21 located at the bottom inner side of the first operating chamber 11 and a circuit board assembly 22 located on the inner side wall of the first operating chamber 11. The circuit board assembly 22 is electrically connected to various electrical units in the hydrogen production mechanism (such as water pump 321, solenoid valves, sensors, etc.) for controlling their coordinated operation. To further enhance human-machine interaction and safety, a control screen 23, an emergency stop button 24, and a buzzer 25 are also provided on the front panel of the first operating chamber 11. These are all electrically connected to the circuit board assembly 22, facilitating operators to monitor equipment status and perform emergency interventions.

[0026] The hydrogen production mechanism is the core functional part of the equipment, comprising a water supply component 30, an electrolyzer 400, a gas-liquid separation component 40, and a hydrogen purification component 50. The electrolyzer 400 is located at the bottom center of the second operating chamber 12; the water supply component 30 is located on the side wall adjacent to the first operating chamber 11; the gas-liquid separation component 40 is located on the rear side wall; and the hydrogen purification component 50 is located on the side wall away from the first operating chamber 11. This layout follows the "water supply-electrolysis-separation-purification" process flow, with the electrolyzer 400 at the center, forming a surrounding, modular, three-dimensional layout within the second operating chamber 12. Specifically, placing the electrolyzer 400 at the bottom center provides the shortest possible flow path connection radius for each functional component, greatly optimizing space utilization. Furthermore, the arrangement of each component around the electrolyzer 400 avoids pipeline interference, effectively reducing pipeline pressure drop and gas purity loss during transmission, thus improving overall efficiency. At the same time, this clearly defined layout physically separates water and electricity (water supply component 30) and gas circuits (gas-liquid separation component 40 and hydrogen purification component 50), facilitating modular installation, inspection and maintenance.

[0027] The second operating chamber 12 has a sampling gas port 71, a hydrogen outlet 61, and an air vent 81 on its side panel away from the first operating chamber 11. The inner sides of the sampling gas port 71, the hydrogen outlet 61, and the air vent 81 are respectively connected to the sampling pipeline 70, the hydrogen outlet 60, and the air vent 80. The other ends of the sampling pipeline 70, the hydrogen outlet 60, and the air vent 80 are all connected to the hydrogen purification component 50.

[0028] The following is a detailed description of each component of the hydrogen production unit: A water supply assembly 30 is installed on the side wall of the second operating chamber 12, adjacent to the first operating chamber 11.

The water supply pipeline 33 transports the purified deionized water to the electrolysis cell 400. A first pressure sensor 331, a first conductivity sensor 332, and a first flow meter 333 are installed on the water supply pipeline 33 for monitoring. The water tank 31 is also connected to an inlet pipe 311 equipped with a first solenoid valve. The water tank 31 is also equipped with a first liquid level sensor 312, a first temperature sensor 313, and a first hydrogen sensor 314 to achieve automatic water replenishment and safety monitoring.

[0029] Electrolyzer 400 is located at the bottom center of the second operating chamber 12, serving as the core of the hydrogen production reaction. This location allows the electrolyzer 400 to easily receive water from the side wall water supply assembly 30, and to directly supply the generated hydrogen and oxygen to the gas-liquid separation assembly 40 above and the hydrogen purification assembly 50 to the side and rear, respectively, making the flow path the most direct.

This assembly includes a hydrogen delivery pipeline 41, a gas-liquid separator 42 (such as a wire mesh filter) mounted on the hydrogen delivery pipeline 41, and a second liquid level sensor 43 connected to the gas-liquid separator 42 for monitoring the liquid level. One end of the hydrogen delivery pipeline 41 is connected to the hydrogen outlet of the electrolyzer 400, and the other end is connected to the subsequent hydrogen purification assembly 50. Along the hydrogen flow direction, a second radiator 414, a second pressure sensor 411, a first check valve 412, and a third pressure sensor 413 are sequentially arranged on the hydrogen delivery pipeline 41 between the electrolyzer 400 and the gas-liquid separator 42 for cooling the produced hot and humid hydrogen and controlling its flow direction.

[0031] A hydrogen purification assembly 50 is disposed on the side wall of the second operating chamber 12, away from the first operating chamber 11. The hydrogen purification assembly 50 includes a first purification tank 51 and a second purification tank 52 arranged in parallel. A sixth solenoid valve 53 is connected to the inlet of the first purification tank 51, and a seventh solenoid valve 54 is connected to the inlet of the second purification tank 52. By controlling the opening and closing of the sixth solenoid valve 53 and the seventh solenoid valve 54, the first purification tank 51 and the second purification tank 52 can be alternately operated and regenerated, thereby ensuring a continuous and stable output of high-purity hydrogen.

[0032] To facilitate the diversion and collection of purified gas, a three-way fitting 55 is also provided. The first port of the three-way fitting 55 is connected to the first outlet pipe 511 of the first purification tank 51 via a second one-way valve 57; the second port is connected to the second outlet pipe 521 of the second purification tank 52 via a third one-way valve 58; and the third port is connected to a manifold 56, on which a second manual needle valve 59 is provided.

This system is used to output high-purity hydrogen.

[0034] 2. Sampling System: The manifold branch pipe 56 is also connected to the sampling line 70, the end of which is connected to the sampling gas port 71 on the side panel. A sixth one-way valve 72, a second pressure reducing valve 73, and a dew point meter 74 are sequentially installed on the sampling line 70 for safely and accurately drawing out a portion of the product gas for online quality monitoring.

The end of the venting line 80 is connected to the vent port 81 on the side panel. The venting line 80 is equipped with an eighth solenoid valve 82 and an eighth check valve 83, which are specifically used to safely export and depressurize the high-pressure gas inside the first purification tank 51 or the second purification tank 52.

[0036] 4. Venting System: The hydrogen production unit also includes a venting assembly. A vent port 90 is located on the side panel of the second operating chamber 12, away from the first operating chamber 11. A venting pipeline 91 connects to the inside of the vent port 90.

The ends of the first vent branch pipe 911 and the second vent branch pipe 912 converge and are connected to the vent port 90 via the vent main pipe 913. A water collection buffer tank 96 is located at the junction of the above-mentioned vent pipelines to collect and temporarily store condensate entrained during the venting process, and is equipped with a third liquid level sensor.

[0037] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent.
