Description

Technical Field

[0001] This invention relates to the field of hydrogen production technology, specifically a fully automated high-purity hydrogen production device. Background Technology

[0002] The fully automatic high-purity hydrogen production unit is an automated complete set of equipment that integrates hydrogen production, purification, drying, filtration, fully automatic control, and safety protection. It can continuously produce high-purity hydrogen 24 hours a day. By electrolyzing pure water, water molecules are decomposed into hydrogen and oxygen. It has the characteristics of being pollution-free, high-purity, and simple to operate and maintain. Compared with traditional hydrogen-oxygen generators, hydrogen-oxygen separation is used in metal welding. The flame temperature is adjustable, the safety and reliability are higher, and there is no need to add corrosive liquids.

[0003] Existing high-purity hydrogen production equipment does not have the ability to recycle water resources during the hydrogen production process, and the heat dissipation effect of the produced hydrogen is not ideal, resulting in high humidity in the hydrogen and waste of water resources. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automated high-purity hydrogen preparation device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: the preparation device includes a substrate, a liquid delivery unit, an electrolysis unit, a heat dissipation unit, a gas-liquid separation unit, and a gas drying unit;

[0006] The substrate is equipped with a liquid delivery unit and an electrolysis unit. The gas delivery end of the electrolysis unit is connected in sequence to a heat dissipation unit, a gas-liquid separation unit and a gas drying unit through a pipeline.

[0007] The heat dissipation unit includes a heat exchange component and a flow slowing component;

[0008] The infusion unit includes a storage tank, a circulation pump, a suction tube, an infusion tube, a drain tube, a drain valve, and a return tube;

[0009] A liquid storage tank and a circulation pump are installed on the substrate. The input end of the circulation pump is connected to the liquid storage tank through a suction pipe, and the output end of the circulation pump is connected to the input end of the electrolysis unit through a delivery pipe. A drain pipe is installed on the liquid output end of the gas-liquid separation unit. A drain valve is provided on the drain pipe, and the drain pipe is connected to the input end of the circulation pump through a return pipe.

[0010] In the automated preparation of high-purity hydrogen, the circulation pump is started to transport the liquid in the storage tank to the electrolysis unit through the suction pipe and the delivery pipe for water electrolysis to produce hydrogen. The produced hydrogen gas passes through the heat dissipation unit, the gas-liquid separation unit and the gas drying unit in sequence to improve the purity of the hydrogen gas. At the same time, after the water in the hydrogen gas is separated by the gas-liquid separation unit, the drain valve can be opened to transport the water separated in the gas-liquid separation unit back to the electrolysis unit through the drain pipe and the return pipe, realizing the recycling of water resources. The heat exchange components and the slow flow components can improve the heat dissipation and cooling effect of the hydrogen gas, which can enhance the liquefaction effect of water in the hydrogen gas.

[0011] Furthermore, the heat exchange assembly includes a heat exchange vessel body, a vertical plate, a gas pipe, a baffle, a cooling box, and a partition.

[0012] Two heat exchange vessels are mounted on the substrate. Vertical plates are symmetrically installed within the two vessels, forming a heat exchange chamber. These vertical plates are connected by multiple gas pipes. Multiple baffles are staggered within each vessel, all located within the heat exchange chamber. One end of each vessel has an input and an output end symmetrically arranged vertically. The input end of the vessel is connected to the gas delivery end of the electrolysis unit via a pipe, and the output end is connected to the input end of the gas-liquid separation unit via a pipe. A baffle is installed near the pipe within each vessel, forming an inlet and outlet layer with the vertical plates. The prepared hydrogen enters the inlet layer through the pipe. The baffle allows the hydrogen to pass through two heat exchange chambers via the gas pipes as it is continuously delivered, improving heat dissipation and thus benefiting the subsequent gas-liquid separation unit.

[0013] Furthermore, the heat exchange assembly also includes a cooling tank, a delivery pump, an inlet pipe, a delivery pipe, and a return pipe;

[0014] A cooling box is installed at the bottom of the heat exchange vessel. Inside the cooling box, fixed cooling plates are symmetrically installed on one side, and a delivery pump is installed on the cooling box. The input end of the delivery pump is connected to the output port of the cooling box via an input pipe, and the output end of the delivery pump is connected to the heat exchange chamber via a delivery pipe. The heat exchange chamber is connected to the input port of the cooling box via a return pipe. A flow-slowing component is installed on the cooling box. When hydrogen is introduced into the heat exchange vessel, the delivery pump is activated, and the coolant in the cooling box is delivered to the heat exchange chamber through the input and delivery pipes. At this time, the coolant that has absorbed heat in the heat exchange chamber can flow back to the cooling box through the return pipe, facilitating the fixed cooling plates to cool the heat-carrying coolant. This allows for the recycling of the coolant. Furthermore, the staggered arrangement of multiple baffles improves the contact surface between the coolant and the gas pipe in the heat exchange chamber, ensuring effective heat dissipation for the hydrogen.

[0015] Furthermore, the flow-retarding component includes a drive motor, drive teeth, a rotating shaft, driven teeth, and a transmission chain;

[0016] A drive motor is installed on the cooling box, and drive teeth are installed on the output shaft of the drive motor. Multiple rotating shafts are uniformly rotatable inside the cooling box. Driven teeth are installed on the ends of the multiple rotating shafts near the drive teeth. A transmission chain is sleeved on the drive teeth and the multiple driven teeth. An extension is provided on the rotating shaft. A control component is provided inside the heat exchange vessel. An extension component is provided inside the cooling box. The control component is electrically connected to the drive motor, the extension component, and the extension component.

[0017] The rotation direction of the shaft is opposite to the flow direction of the coolant in the cooling tank.

[0018] When the coolant carrying heat flows back into the cooling tank, the drive motor is started. Through the tooth chain transmission composed of drive teeth, driven teeth and transmission chain, the shaft drives the extension to rotate in the opposite direction of the coolant flow. This slows down the flow time of the coolant in the cooling tank and improves the cooling effect of the fixed cooling fins on the returning coolant.

[0019] Furthermore, the control component includes a heat shield, a thermistor, a power supply, a current sensor, and wires;

[0020] A heat baffle plate is installed at the end of the heat exchange vessel away from the partition, forming an isolation chamber. A thermistor is installed on the heat baffle plate, and a power supply and a current sensor are installed in the isolation chamber. The power supply, the thermistor, and the current sensor are connected in sequence to form a closed circuit. The current sensor is electrically connected to the drive motor. When the heat exchange effect of the heat exchange chamber on hydrogen decreases, the temperature of the hydrogen flowing to the thermistor will be higher than the standard value. At this time, the thermistor can control the resistance to decrease accordingly based on the temperature of the hydrogen exceeding the standard value, and the current detected by the current sensor will increase accordingly. The current sensor can control the rotation speed of the drive motor to increase accordingly, thereby increasing the flow time of the coolant in the cooling tank.

[0021] Furthermore, the extension component includes a turntable, a fixed blade, a slide rail, a slide plate, an extension blade, a connecting rod, and an electric telescopic rod;

[0022] A turntable is mounted on the side of the rotating shaft near the driven gear, and multiple sets of fixed blades are arranged in a circular array on it. Each set of fixed blades has a slide rail, and a slide plate is slidably mounted in the slide rail. An extension blade is mounted on the side of the slide plate away from the turntable. The slide plate is connected to another adjacent extension blade via a connecting rod. Multiple electric telescopic rods are arranged in a circular array on the side of the turntable near the fixed blades. The telescopic end of the electric telescopic rod is connected to the adjacent slide plate on the same side. The electric telescopic rod is electrically connected to a current sensor. When the current intensity detected by the current sensor increases, the current sensor can control the electric telescopic rod to extend by a corresponding length according to the current intensity. At this time, the electric telescopic rod can drive the slide plate to slide in the slide rail during the extension process, thereby controlling the length of the extension blade extending beyond the fixed blade. This can achieve the overlap rate of the fixed blade and the extension blade, making it convenient to control the combined length of the fixed blade and the extension blade according to the increase in current intensity, which is beneficial to improving the stagnation effect on the coolant.

[0023] Furthermore, the extension components include a servo motor, a lead screw, a slider, a slide groove, and a compensating cooling plate;

[0024] The cooling box has a lead screw symmetrically mounted on the inner side away from the fixed cooling element. A servo motor is symmetrically mounted on the cooling box. The servo motor drives the lead screw to rotate. A slider is slidably mounted on the lead screw. The cooling box has symmetrically opened grooves on the inner side away from the fixed cooling element. The slider is slidably fitted into the groove on the same side. A compensating cooling element is mounted on the slider.

[0025] The compensating cooler is the same as the fixed cooler, and in the initial state, the compensating cooler and the fixed cooler overlap and align.

[0026] When the current intensity detected by the current sensor increases, the current sensor can control the servo motor to run. Since the slider can slide in the groove, the servo motor can drive the slider to move a corresponding distance through the lead screw. During the movement, the slider can drive the compensating cooling plate to move synchronously, so that the combined length of the compensating cooling plate and the fixed cooling plate can be automatically adjusted according to the change in the intensity of the detected current, thereby realizing the self-adjustment of the cooling effect of the coolant.

[0027] Furthermore, both the compensating cooler and the fixed cooler are electrically connected to the current sensor, which allows the current sensor to control the cooling effect of the compensating cooler and the fixed cooler accordingly based on the current intensity.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] During the automated preparation of high-purity hydrogen, the prepared hydrogen gas passes through a heat dissipation unit, a gas-liquid separation unit, and a gas drying unit in sequence to improve the purity of the hydrogen gas. At the same time, by opening the drain valve, the water separated in the gas-liquid separation unit can be transported back to the electrolysis unit through the drain pipe and the return pipe, so as to realize the recycling of water resources.

[0030] This application can slow down the flow time of the coolant in the cooling tank, thereby improving the cooling effect of the fixed cooling fins on the returning coolant.

[0031] In this application, the resistance of the thermistor can be reduced accordingly based on the temperature of hydrogen gas exceeding the standard value, and the current sensor can control the rotation speed of the drive motor to be increased accordingly based on the detected current intensity, thereby increasing the flow time of the coolant in the cooling tank.

[0032] This application can control the combined length of the fixed blade and the extended blade according to the increase of current intensity, which is beneficial to improve the stagnation effect on the coolant.

[0033] This application enables the combined length of the compensating coolant and the fixed coolant to be automatically adjusted according to the intensity change of the detected current, thereby achieving self-adjustment of the cooling effect on the coolant. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example: Figures 1-9 As shown, the present invention provides a technical solution for a fully automated high-purity hydrogen preparation device, which includes a substrate 1, a liquid delivery unit 2, an electrolysis unit 3, a heat dissipation unit 4, a gas-liquid separation unit 5, and a gas drying unit 6.

[0046] A liquid delivery unit 2 and an electrolysis unit 3 are installed on the substrate 1. The gas delivery end of the electrolysis unit 3 is connected in sequence to a heat dissipation unit 4, a gas-liquid separation unit 5 and a gas drying unit 6 through a pipe.

[0047] The heat dissipation unit 4 includes a heat exchange component and a flow slowing component 7;

[0048] The infusion unit 2 includes a storage tank 201, a circulation pump 202, a suction pipe 203, an infusion pipe 204, a drain pipe 205, a drain valve 206, and a return pipe 207;

[0049] A liquid storage tank 201 and a circulation pump 202 are installed on the base 1. The input end of the circulation pump 202 is connected to the liquid storage tank 201 through a suction pipe 203, and the output end of the circulation pump 202 is connected to the input end of the electrolysis unit 3 through a delivery pipe 204. A drain pipe 205 is installed on the liquid output end of the gas-liquid separation unit 5. A drain valve 206 is provided on the drain pipe 205, and the drain pipe 205 is connected to the input end of the circulation pump 202 through a return pipe 207.

[0050] When performing automated high-purity hydrogen production, the circulation pump 202 is started, and the liquid in the storage tank 201 is transported to the electrolysis unit 3 through the suction pipe 203 and the delivery pipe 204 for water electrolysis to produce hydrogen. The produced hydrogen gas passes through the heat dissipation unit 4, the gas-liquid separation unit 5 and the gas drying unit 6 in sequence to improve the purity of the hydrogen gas. At the same time, after the water in the hydrogen gas is separated by the gas-liquid separation unit 5, the drain valve 206 can be opened, and the water separated in the gas-liquid separation unit 5 can be transported back to the electrolysis unit 3 through the drain pipe 205 and the return pipe 207 to realize the recycling of water resources. The heat exchange component and the slow flow component 7 can improve the heat dissipation and cooling effect of the hydrogen gas, and enhance the liquefaction effect of water in the hydrogen gas.

[0051] The heat exchange assembly includes a heat exchange vessel body 401, a vertical plate 402, a gas pipe 403, a baffle 404, a cooling box 405, and a partition 410;

[0052] Two heat exchange vessel bodies 401 are mounted on the base 1. Vertical plates 402 are symmetrically installed inside the two heat exchange vessel bodies 401, forming a heat exchange chamber. The vertical plates 402 are connected by multiple gas pipes 403. Multiple baffles 404 are staggered inside the heat exchange vessel bodies 401, and all baffles 404 are located within the heat exchange chamber. One end of each heat exchange vessel body 401 has an input end and an output end symmetrically arranged vertically. The input end of the heat exchange vessel body 401 is connected to the gas delivery end of the electrolysis unit 3 via a pipe. The output end is connected to the input end of the gas-liquid separation unit 5 through a pipe. A baffle 410 is provided at one end of the heat exchange vessel 401 near the pipe. The baffle 410 and the vertical plate 402 form an inlet layer and an outlet layer. The prepared hydrogen enters the inlet layer in the heat exchange vessel 401 through the pipe. With the setting of the baffle 410, as the hydrogen is continuously transported, the hydrogen can pass through the gas pipe 403 through two heat exchange chambers, which improves the heat dissipation effect of the hydrogen, thereby benefiting the gas-liquid separation effect of the subsequent gas-liquid separation unit 5.

[0053] The heat exchange assembly also includes a cooling box 405, a transfer pump 406, an inlet pipe 407, a transfer pipe 408, and a return pipe 409;

[0054] A cooling box 405 is installed at the bottom of the heat exchange vessel 401. Fixed cooling plates 711 are symmetrically installed on one side of the interior of the cooling box 405. A delivery pump 406 is installed on the cooling box 405. The input end of the delivery pump 406 is connected to the output port of the cooling box 405 through an input pipe 407, and the output end of the delivery pump 406 is connected to the heat exchange chamber through a delivery pipe 408. The heat exchange chamber is connected to the input port of the cooling box 405 through a return pipe 409. A flow-retarding component 7 is provided on the cooling box 405. When hydrogen gas is introduced into the heat exchange vessel 401... When the coolant is in the heat exchange chamber, the coolant in the cooling tank 405 can be transported to the heat exchange chamber through the input pipe 407 and the delivery pipe 408 by starting the delivery pump 406. At this time, the coolant that has absorbed heat in the heat exchange chamber can be returned to the cooling tank 405 through the return pipe 409, which makes it easier for the fixed cooling plate 711 to cool the coolant carrying heat. This allows for the recycling of the coolant. Furthermore, the multiple baffles 404 arranged in a staggered manner can improve the contact surface between the coolant and the gas pipe 403 in the heat exchange chamber, ensuring the heat dissipation effect on the hydrogen.

[0055] The flow control assembly 7 includes a drive motor 701, a drive gear 702, a rotating shaft 703, a driven gear 704, and a transmission chain 705;

[0056] A drive motor 701 is installed on the cooling box 405. A drive gear 702 is installed on the output shaft of the drive motor 701. Multiple rotating shafts 703 are evenly rotated inside the cooling box 405. Driven gears 704 are installed at the ends of the multiple rotating shafts 703 near the drive gears 702. A transmission chain 705 is sleeved on the drive gears 702 and the multiple driven gears 704. An extension member 8 is provided on the rotating shaft 703. A control component is provided inside the heat exchange vessel body 401. An extension member 9 is provided inside the cooling box 405. The control component is electrically connected to the drive motor 701, the extension member 8 and the extension member 9.

[0057] The rotation direction of the shaft 703 is opposite to the flow direction of the coolant in the cooling tank 405.

[0058] When the coolant carrying heat flows back into the cooling tank 405, the drive motor 701 is started. Through the tooth chain transmission composed of the drive gear 702, the driven gear 704 and the transmission chain 705, the rotating shaft 703 drives the extension member 8 to rotate in the opposite direction of the coolant flow. This can slow down the flow time of the coolant in the cooling tank 405 and improve the cooling effect of the fixed cooling plate 711 on the returning coolant.

[0059] The control components include a heat shield 706, a thermistor 707, a power supply 708, a current sensor 709, and a wire 710.

[0060] A heat baffle plate 706 is installed at the end of the heat exchange vessel 401 away from the partition plate 410, forming an isolation chamber. A thermistor 707 is installed on the heat baffle plate 706. A power supply 708 and a current sensor 709 are installed in the isolation chamber. The power supply 708, the thermistor 707, and the current sensor 709 are connected in sequence to form a closed circuit through wires 710. The current sensor 709 is electrically connected to the drive motor 701. When the heat exchange effect of the heat exchange chamber on hydrogen decreases, the temperature of the hydrogen flowing to the thermistor 707 will be higher than the standard value. At this time, the thermistor 707 can control the resistance to decrease accordingly based on the temperature of the hydrogen exceeding the standard value. The current detected by the current sensor 709 will increase accordingly. The current sensor 709 can control the rotation speed of the drive motor 701 to increase accordingly, thereby increasing the flow time of the coolant in the cooling tank 405.

[0061] The extension component 8 includes a turntable 801, a fixed blade 802, a slide rail 803, a slide plate 804, an extension blade 805, a connecting rod 806, and an electric telescopic rod 807.

[0062] A turntable 801 is mounted on the side of the rotating shaft 703 near the driven gear 704, and multiple sets of fixed blades 802 are mounted on it in a circumferential array. Each set of fixed blades 802 has a slide rail 803, within which a slide plate 804 is slidably mounted. An extension blade 805 is mounted on the side of the slide plate 804 away from the turntable 801. The slide plate 804 is connected to another adjacent extension blade 805 via a connecting rod 806. Multiple electric telescopic rods 807 are mounted in a circumferential array on the side of the turntable 801 near the fixed blades 802. The telescopic ends of the electric telescopic rods 807 are connected to the adjacent slide plate 804 on the same side. 7 is electrically connected to the current sensor 709. When the current intensity detected by the current sensor 709 increases, the current sensor 709 can control the electric telescopic rod 807 to extend to a corresponding length according to the current intensity. At this time, the electric telescopic rod 807 can drive the slide plate 804 to slide in the slide rail 803 during the extension process, thereby controlling the length of the extension blade 805 extending out of the fixed blade 802. This can realize the overlap rate between the fixed blade 802 and the extension blade 805, making it convenient to control the combined length of the fixed blade 802 and the extension blade 805 according to the increase in current intensity, which is beneficial to improving the stagnation effect on the coolant.

[0063] The extension component 9 includes a servo motor 901, a lead screw 902, a slider 903, a slide groove 904, and a compensating cooling plate 905;

[0064] A lead screw 902 is symmetrically mounted on the inner side of the cooling box 405 away from the fixed cooling plate 711. A servo motor 901 is symmetrically mounted on the cooling box 405. The servo motor 901 drives the lead screw 902 to rotate. A slider 903 is slidably mounted on the lead screw 902. A sliding groove 904 is symmetrically opened on the inner side of the cooling box 405 away from the fixed cooling plate 711. The slider 903 is slidably fitted into the sliding groove 904 on the same side. A compensating cooling plate 905 is mounted on the slider 903.

[0065] The compensating cooler 905 is identical to the fixed cooler 711, and in the initial state, the compensating cooler 905 and the fixed cooler 711 overlap and align.

[0066] When the current intensity detected by the current sensor 709 increases, the current sensor 709 can control the servo motor 901 to run. Since the slider 903 can slide in the groove 904, the servo motor 901 can drive the slider 903 to move a corresponding distance through the lead screw 902. During the movement, the slider 903 can drive the compensating cooling plate 905 to move synchronously, so that the combined length of the compensating cooling plate 905 and the fixed cooling plate 711 can be automatically adjusted according to the change in the intensity of the detected current, thereby realizing the self-adjustment of the cooling effect of the coolant.

[0067] Both the compensating cooler 905 and the fixed cooler 711 are electrically connected to the current sensor 709, which allows the current sensor 709 to control the cooling effect of the compensating cooler 905 and the fixed cooler 711 accordingly based on the current intensity.

[0068] Working principle of the invention:

[0069] When performing automated high-purity hydrogen production, the circulation pump 202 is started, and the liquid in the storage tank 201 is transported to the electrolysis unit 3 through the suction pipe 203 and the delivery pipe 204 for water electrolysis to produce hydrogen. The produced hydrogen gas passes through the heat dissipation unit 4, the gas-liquid separation unit 5 and the gas drying unit 6 in sequence to improve the purity of the hydrogen gas. At the same time, after the water in the hydrogen gas is separated by the gas-liquid separation unit 5, the drain valve 206 can be opened, and the water separated in the gas-liquid separation unit 5 can be transported back to the electrolysis unit 3 through the drain pipe 205 and the return pipe 207 to realize the recycling of water resources.

[0070] The prepared hydrogen enters the air inlet layer inside the heat exchange vessel 401 through a pipe. With the setting of the baffle 410, the hydrogen can pass through the gas pipe 403 through two heat exchange chambers as the hydrogen is continuously transported, which improves the heat dissipation effect of the hydrogen. This is beneficial to the gas-liquid separation effect of the subsequent gas-liquid separation unit 5. When the hydrogen enters the heat exchange vessel 401, the delivery pump 406 is started, and the coolant in the cooling box 405 is transported to the heat exchange chamber through the input pipe 407 and the delivery pipe 408. At this time, the coolant that has absorbed heat in the heat exchange chamber can flow back to the cooling box 405 through the return pipe 409, which makes it easier for the fixed cooling plate 711 to cool the coolant carrying heat. The coolant can be recycled. With the multiple baffles 404 arranged in a staggered manner, the contact surface between the coolant and the gas pipe 403 in the heat exchange chamber can be improved, which can ensure the heat dissipation effect of the hydrogen.

[0071] When the coolant carrying heat flows back into the cooling tank 405, the drive motor 701 is started. Through the tooth chain transmission composed of the drive gear 702, the driven gear 704 and the transmission chain 705, the rotating shaft 703 drives the extension member 8 to rotate in the opposite direction of the coolant flow. This can slow down the flow time of the coolant in the cooling tank 405 and improve the cooling effect of the fixed cooling plate 711 on the returning coolant.

[0072] When the heat exchange effect of the heat exchange chamber on hydrogen decreases, the temperature of the hydrogen flowing to the thermistor 707 will be higher than the standard value. At this time, the thermistor 707 can control the resistance to decrease accordingly based on the temperature of the hydrogen being higher than the standard value. The current detected by the current sensor 709 will increase accordingly. The current sensor 709 can control the rotation speed of the drive motor 701 to increase accordingly, thereby increasing the flow time of the coolant in the cooling tank 405.

[0073] When the current intensity detected by the current sensor 709 increases, the current sensor 709 can control the electric telescopic rod 807 to extend to a corresponding length according to the current intensity. At this time, the electric telescopic rod 807 can drive the slide plate 804 to slide in the slide rail 803 during the extension process, thereby controlling the length of the extension blade 805 extending out of the fixed blade 802. This can achieve the overlap rate between the fixed blade 802 and the extension blade 805, making it easier to control the combined length of the fixed blade 802 and the extension blade 805 according to the increase in current intensity, which is beneficial to improving the stagnation effect on the coolant.

[0074] When the current intensity detected by the current sensor 709 increases, the current sensor 709 can control the servo motor 901 to run. Since the slider 903 can slide in the groove 904, the servo motor 901 can drive the slider 903 to move a corresponding distance through the lead screw 902. During the movement, the slider 903 can drive the compensating cooling plate 905 to move synchronously, so that the combined length of the compensating cooling plate 905 and the fixed cooling plate 711 can be automatically adjusted according to the change in the intensity of the detected current, thereby realizing the self-adjustment of the cooling effect of the coolant.
