Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, and in particular to a rapid hydrogen extraction device. Background Technology

[0002] Hydrogen-rich rapid extraction equipment is of great significance for promoting the development of clean energy and is widely used in various fields such as energy and chemicals. In the energy sector, it can provide high-purity hydrogen for fuel cell vehicles, helping to improve their range and performance; in the chemical industry, high-purity hydrogen is a key raw material for many chemical synthesis reactions. By rapidly and efficiently extracting hydrogen-rich gas from various raw materials, this equipment helps meet the stringent requirements of different industries for hydrogen purity and yield, promoting green and sustainable industrial development. Currently, the following technologies are typically required for the practical application of hydrogen-rich rapid extraction equipment:

[0003] 1. Highly efficient reaction catalysis technology can accelerate the conversion rate of raw materials into hydrogen and increase the hydrogen production per unit time;

[0004] 2. Precise gas separation technology can accurately separate high-purity hydrogen from mixed gases and remove various impurities;

[0005] 3. Stable thermal management technology ensures that the reaction process is carried out at a suitable temperature, avoiding the impact of temperature fluctuations on reaction efficiency and equipment stability.

[0006] Currently, various equipment and methods are employed to achieve rapid hydrogen extraction. Some devices are based on the principle of water electrolysis, using an electrolyzer to produce hydrogen. These devices are typically equipped with high-performance electrode materials to reduce energy consumption. Other devices utilize chemical reforming, using natural gas, methanol, or other raw materials as feedstocks, and producing hydrogen through a reforming reaction under the action of a catalyst. These devices are often equipped with advanced heating and temperature control systems. Additionally, some devices employ bio-hydrogen production technology, utilizing microorganisms to produce hydrogen through metabolism under specific conditions, which generally requires precise control of the bioreaction environment.

[0007] However, the above method has a prominent problem: the existing device lacks a dynamic swing feeding function when feeding raw materials and reactants. The material that falls along the inner wall of the feeding pipe has a relatively concentrated landing point and is unevenly distributed in the reaction area. This limits the contact area between the material and the catalyst, increases the time required for sufficient mixing and contact, reduces reaction efficiency, and reduces the amount of hydrogen produced per unit time. Utility Model Content

[0008] To address the shortcomings of existing technologies, this invention provides a rapid hydrogen extraction device that solves the problem of lacking dynamic oscillating feeding function during the feeding of raw materials and reactants. The material falling only along the inner wall of the feeding pipe has a relatively concentrated landing point and uneven distribution in the reaction area. This limits the contact area between the material and the catalyst, increases the time required for sufficient mixing and contact, reduces reaction efficiency, and decreases the hydrogen production per unit time.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A rapid hydrogen extraction device includes a reactor. The reactor is equipped with a feeding mechanism for extraction and feeding, which includes a feeding hopper rotatably connected inside the reactor. The reactor is also equipped with a reciprocating mechanism for oscillating feeding, comprising an L-shaped push plate, a pin, and a rotating column. The L-shaped push plate is fixedly connected to the outer surface of the feeding hopper, the pin is fixedly connected to the lower end of the L-shaped push plate, and the rotating column is rotatably connected inside the reactor. A guide groove is formed inside the rotating column, and the pin is sleeved inside the guide groove.

[0011] Preferably, a rotating shaft is fixedly connected to the lower end of the feeding hopper, and a bearing is sleeved inside the reaction vessel.

[0012] Preferably, the bearing is sleeved on the outer surface of the rotating shaft, and a drive motor is fixedly connected to the outer surface of the reaction vessel.

[0013] Preferably, the rotating column is sleeved on the outer surface of the drive motor, and a discharge valve is fixedly connected inside the reaction vessel.

[0014] Preferably, a gate valve is fixedly connected to the upper end of the reaction vessel, and a separation vessel is fixedly connected to the upper end of the gate valve.

[0015] Preferably, the reactor is provided with a set of bolts, all of which are threaded into the interior of the separation vessel.

[0016] Preferably, an exhaust flange is fixedly connected to the upper end of the separation vessel, and a wire mesh demister is sleeved inside the separation vessel.

[0017] Preferably, a filter separation membrane is fitted inside the separation vessel at one end near the wire mesh demister, and adsorbent material is fitted inside the separation vessel at the other end near the filter separation membrane.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. After feeding is completed, start the drive motor. The drive motor drives the rotating column sleeved on its outer surface to rotate. The rotating column has a wave-shaped guide groove inside. The pin at the lower end of the L-shaped push plate is sleeved in the guide groove. When the rotating column rotates, the pin swings back and forth along the wave-shaped inner wall of the guide groove. The pin drives the L-shaped push plate, which in turn drives the feeding hopper fixed on the outer surface of the L-shaped push plate to swing back and forth around the rotating shaft. Through this swing feeding method, the raw material covers a larger area in a dynamic form and comes into more comprehensive contact with the catalyst, avoiding the problem of low local utilization of the catalyst, accelerating the reaction rate, and quickly completing the extraction work, thereby increasing the product generation per unit time.

[0020] 2. The gas generated by the reaction enters upward into the channel connecting the reactor and the separation vessel. A gate valve is installed in the channel, which is connected to the reactor and the separation vessel via flanges and bolts. By tightening the bolts and nuts, the stability of the connection between the reactor and the separation vessel is enhanced, ensuring the sealing and safety of the gas transmission process. After the gas is generated, it can directly enter the separation stage by utilizing its natural upward floating characteristic, realizing the efficient integration of the reaction and separation processes. The gas can smoothly enter the separation vessel from the reactor, allowing the reactor to continuously react and the separation vessel to continuously separate the gas. This avoids production interruptions caused by poor gas transmission or waiting, further improving the production capacity and operating efficiency of the equipment. Attached Figure Description

[0028] This application provides a hydrogen-rich rapid extraction device that effectively solves the problem of the lack of dynamic oscillating feeding function during the feeding of raw materials and reactants. Materials falling only along the inner wall of the feeding pipe have a relatively concentrated landing point and uneven distribution within the reaction area. This limits the contact area between the material and the catalyst, increases the time required for thorough mixing and contact, reduces reaction efficiency, and decreases the hydrogen production per unit time. After feeding is completed, the drive motor is started, which drives a rotating column fitted on its outer surface to rotate. The rotating column has a wave-shaped guide groove inside, and the pin at the lower end of the L-shaped push plate is fitted inside the guide groove. When the rotating column rotates, the pin oscillates back and forth along the wave-shaped inner wall of the guide groove. Through this oscillating feeding method, the raw material dynamically covers a larger area, making more comprehensive contact with the catalyst, avoiding the problem of low local catalyst utilization, accelerating the reaction rate, and quickly completing the extraction process, thus increasing the product production per unit time. Example

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that the device lacks a dynamic oscillating feeding function during the feeding and loading of raw materials and reactants. The material falling only along the inner wall of the feeding pipe has a relatively concentrated landing point and uneven distribution within the reaction area. This limits the contact area between the material and the catalyst, increases the time required for sufficient mixing and contact, reduces reaction efficiency, and decreases the hydrogen production per unit time. The overall concept is as follows: A hydrogen-rich rapid extraction device includes a reaction vessel 11, inside which is a feeding mechanism for extraction and loading, including a feeding hopper. 12. The feeding hopper 12 is rotatably connected to the inside of the reactor 11. Raw materials and reactants for generating hydrogen are fed into the reactor 11 through the feeding hopper 12 for reaction processing. When selecting raw materials, hydrogen-rich organic compounds such as methanol and ethanol are chosen. The feeding hopper 12 is placed at an incline to ensure that the raw materials and reactants can fall along the inclined inner wall. The feeding hopper 12 can be sealed during reaction by installing a cover. The reactor 11 is equipped with a reciprocating mechanism for oscillating feeding. The reciprocating mechanism includes an L-shaped push plate 13, a shaft pin 14, and a rotating column 15. The L-shaped push plate 13 is fixedly connected to the feeding hopper 11. On the outer surface of the hopper 12, a shaft pin 14 is fixedly connected to the lower end of the L-shaped push plate 13. A rotating column 15 is rotatably connected to the inside of the reactor 11. A guide groove 16 is opened inside the rotating column 15. The guide groove 16 is wavy. The shaft pin 14 is sleeved inside the guide groove 16. The rotation of the rotating column 15 drives the shaft pin 14 to slide along the inner wall of the guide groove 16. The shaft pin 14 and the L-shaped push plate 13 drive the feeding hopper 12 to swing back and forth to perform the feeding operation. By swinging the feeding method, the raw materials can dynamically cover a larger area and have more comprehensive contact with the catalyst, allowing more raw material molecules to react with the catalyst in a timely manner. The active sites of the chemical agent come into contact and react, thereby significantly accelerating the reaction rate and increasing the product generation per unit time. A rotating shaft 17 is fixedly connected to the lower end of the feeding hopper 12. A bearing 18 is sleeved inside the reaction vessel 11 and sleeved on the outer surface of the rotating shaft 17. A drive motor 19 is fixedly connected to the outer surface of the reaction vessel 11, and a rotating column 15 is sleeved on the outer surface of the drive motor 19. The feeding hopper 12 will rotate around the rotating shaft 17. The bearing 18 sleeved inside the reaction vessel 11 can improve the smoothness of the rotation of the rotating shaft 17. The drive motor 19 serves as a power source to drive the rotating column 15 to rotate for oscillation.

[0030] A discharge valve 21 is fixedly connected inside the reactor 11. After the raw materials and reactants come into full contact, gas is generated. Due to the density difference of the gases, the gas generated by the reaction floats upward. After the hydrogen is collected and processed, the waste material after the reaction is discharged through the discharge valve 21. A gate valve 22 is fixedly connected to the upper end of the reactor 11, and a separation vessel 23 is fixedly connected to the upper end of the gate valve 22. The reactor 11 and the separation vessel 23 are connected by the gate valve 22, flange, and bolts. The gas flow opening is opened or closed by turning the separation vessel 23, and the channel size can be controlled by the separation vessel 23 (the gate of the separation vessel 23 moves vertically along the center line of the valve seat). By changing the flow area between the gate and the valve seat, the gas flow rate can be adjusted. When the gate is fully open, the fluid resistance is small and the gas can pass through smoothly. When the gate is partially open, the gas flow rate can be controlled according to the degree of opening. A set of bolt rods 24 are installed inside the reactor 11. All bolt rods 24 are threadedly connected to the inside of the separation vessel 23. The stability of the connection between the reactor 11 and the separation vessel 23 is enhanced by tightening the bolt rods 24 and nuts. Through the connected installation design of the reactor 11 and the separation vessel 23, the gas can directly enter the separation stage by taking advantage of its natural upward floating characteristic after it is generated, which may achieve a more efficient integration of the reaction and separation processes.

[0031] An exhaust flange 25 is fixedly connected to the upper end of the separation vessel 23. A wire mesh demister 26 is sleeved inside the separation vessel 23. A filter separation membrane 27 is sleeved at one end of the separation vessel 23 near the wire mesh demister 26. An adsorbent material 28 is sleeved at the other end of the separation vessel 23 near the filter separation membrane 27. The gas after reaction treatment is separated in the separation vessel 23. During the separation process, the wire mesh demister 26 intercepts any liquid droplets or solid particles that may be carried in the gas. The gas after the liquid droplets or solid particles are removed is adsorbed and separated by the filter separation membrane 27 and the adsorbent material 28, thereby achieving gradual purification of the gas to increase the hydrogen concentration in the final product gas, making it hydrogen-rich and making the product more in line with the hydrogen purity requirements of specific application scenarios.

[0032] To address the problems existing in the prior art, this utility model provides a rapid hydrogen extraction device. After feeding is completed, the drive motor 19 is started, which drives the rotating column 15 sleeved on its outer surface to rotate. The rotating column 15 has a wave-shaped guide groove 16 inside. The pin 14 at the lower end of the L-shaped push plate 13 is sleeved inside the guide groove 16. When the rotating column 15 rotates, the pin 14 swings back and forth along the wave-shaped inner wall of the guide groove 16. The pin 14 drives the L-shaped push plate 13, which in turn drives the feeding hopper 12 fixed on the outer surface of the L-shaped push plate 13 to swing back and forth around the rotating shaft 17. Through this swing feeding method, the raw material covers a larger area in a dynamic form, making more comprehensive contact with the catalyst, avoiding the problem of low local utilization of the catalyst, accelerating the reaction rate, and quickly completing the extraction work, thereby increasing the product generation per unit time.

[0049] Adsorbent 28: Further adsorbs impurities and increases hydrogen concentration to meet purity requirements.

[0050] Working principle:

[0051] First, the raw materials for generating hydrogen (such as hydrogen-rich organic compounds like methanol and ethanol) and reactants are fed into the reactor 11 through the feeding hopper 12. The raw materials and reactants in the reactor 11 come into full contact and react to generate hydrogen-containing gas. Due to the density difference, the gas rises. After the hydrogen is collected, the discharge valve 21 inside the reactor 11 is opened to discharge the reacted waste. Simultaneously, the gas generated rises into the channel connecting the reactor 11 and the separation vessel 23. A gate valve 22 is installed in the channel, connected to the reactor 11 and the separation vessel 23 via flanges and bolts. By rotating the separation vessel 23 (the gate moves vertically along the center line of the valve seat), the flow area between the gate and the valve seat can be changed, thereby adjusting the gas flow rate. When the gate is fully open, the fluid resistance is low, and the gas can pass smoothly. When the gate is partially open, the gas flow rate can be precisely controlled according to the degree of opening. Furthermore, a set of bolts 24 inside the reactor 11 is threaded into the separation vessel 23. The bolt rod 24 and nut enhance the stability of the connection between the reaction vessel 11 and the separation vessel 23, ensuring the sealing and safety of the gas transmission process. After the gas is generated, it can directly enter the separation stage by utilizing its natural upward floating characteristic, achieving efficient integration of the reaction and separation processes. After the gas enters the separation vessel 23, it first passes through the wire mesh demister 26. The wire mesh demister 26 intercepts any liquid droplets or solid particles that may be carried in the gas, preventing them from affecting the subsequent separation process. After demistering and removing solid particles, the gas is then adsorbed and separated by the filter separation membrane 27 and the adsorbent material 28. The filter separation membrane 27 uses its special pore structure and selective permeability to block some impurity gas from passing through, making hydrogen relatively rich. The adsorbent material 28 further adsorbs the remaining impurities through physical or chemical adsorption, achieving gradual purification of the gas. After the above separation process, the hydrogen concentration in the product gas is ultimately increased, making it hydrogen-rich and meeting the hydrogen purity requirements of specific application scenarios. The separated hydrogen-rich gas is finally discharged through the exhaust flange 25 at the upper end of the separation vessel 23.

[0052] The second step involves starting the drive motor 19 after feeding. The drive motor 19 drives the rotating column 15, which is sleeved on its outer surface, to rotate. The rotating column 15 has a wave-shaped guide groove 16 inside. The pin 14 at the lower end of the L-shaped push plate 13 is sleeved inside the guide groove 16. When the rotating column 15 rotates, the pin 14 swings back and forth along the wave-shaped inner wall of the guide groove 16. The pin 14 drives the L-shaped push plate 13, which in turn drives the feeding hopper 12, which is fixed on the outer surface of the L-shaped push plate 13, to swing back and forth around the rotating shaft 17. The rotating shaft 17 at the lower end of the feeding hopper 12 is sleeved in the bearing 18 inside the reactor 11. The bearing 18 improves the smoothness of the rotation of the rotating shaft 17, allowing the feeding hopper 12 to swing back and forth stably for feeding. Through this swing feeding method, the raw materials cover a larger area in a dynamic form (the more uniformly distributed materials can be stirred and mixed faster), and come into more comprehensive contact with the catalyst, accelerating the reaction rate and increasing the product generation per unit time.

[0053] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
