Description

Technical Field

[0001] This utility model relates to the field of hydrogen pressure stabilization supply technology, and in particular to a hydrogen pressure stabilization supply device with hydrogen-rich carbon cycle. Background Technology

[0002] In the hydrogen-rich carbon cycle, hydrogen is a key reactant, and the stability of its supply is crucial for the efficient operation of the entire cycle system. However, existing hydrogen supply devices often struggle to ensure stable hydrogen pressure under complex hydrogen-rich carbon cycle conditions. For example, in traditional devices, fluctuations in gas flow rate and changes in reaction load can cause significant fluctuations in hydrogen output pressure. This not only affects the rate and effectiveness of the chemical reaction but may also lead to equipment damage and increased maintenance costs.

[0003] When in use, traditional devices experience significant fluctuations in hydrogen output pressure due to gas flow rate fluctuations and changes in reaction load. Furthermore, hydrogen-rich carbon cycles require dried and heated hydrogen, which is difficult to dry and heat in most existing devices. Therefore, we propose a hydrogen pressure stabilization supply device for hydrogen-rich carbon cycles. Utility Model Content

The bevel gear is fixedly mounted on the outside of the rotating shaft and the drive shaft, with adjacent bevel gears meshing. The fan blade is fixedly mounted on the outside of the rotating shaft and the drive shaft for one revolution. The heating resistance wire is fixedly mounted on the bottom inner wall of the hydrogen heating box. The input end of the hot gas transmission pipe is fixedly mounted on the top of the hydrogen heating box, and the output end of the hot gas transmission pipe is fixedly mounted on the inside of the heating pipe.

[0010] By adopting the above technical solution, after the sealing baffle slides into the inner side of the storage groove, the desiccant pack placement frame loses its limit and can be popped out by the second spring below, making it convenient for staff to take out and replace the desiccant pack inside the desiccant pack placement frame. After replacement, the desiccant pack placement frame can be pressed into the inner side of the hydrogen drying box. The heating resistance wire is started, and the motor drives the drive shaft and fan blades to rotate. After the fan blades rotate, the outside air can enter and be heated by the heating resistance wire. The warmer air inside the hydrogen heating box can heat the hydrogen drying box.

[0031] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings;

[0032] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] refer to Figure 1-6A hydrogen pressure stabilization supply device for hydrogen-rich carbon cycle includes a hydrogen heating box 3 and a mounting frame 6. A hydrogen drying box 4 is fixedly installed inside the hydrogen heating box 3, and a heating pipe 10 is fixedly installed on the right side of the hydrogen drying box 4. A hydrogen heating and drying supply assembly 1 is arranged above the hydrogen heating box 3, the hydrogen drying box 4, the mounting frame 6, and the heating pipe 10. The necessity of hydrogen drying: If the hydrogen contains moisture, it may react with other substances during the experiment to generate acidic substances, or directly form an electrolyte solution on the equipment surface, causing electrochemical corrosion, shortening the service life of the equipment, and affecting the normal progress of the experiment. Many hydrogen-rich carbon cycle experiments use catalysts. The presence of moisture may occupy the active sites of the catalyst or cause chemical reactions, leading to a decrease in catalyst activity or even deactivation, thus affecting the efficiency and selectivity of the reaction and causing deviations in experimental results. Hydrogen heating can increase the reaction rate; according to the Arrhenius equation, as the temperature increases, the reaction rate constant increases, thereby accelerating the reaction rate. In carbon cycle experiments, many reactions have very slow reaction rates at room temperature, making it difficult to obtain sufficient products for analysis and research within a limited experimental time. Heating hydrogen provides sufficient energy to the reaction, making hydrogen molecules more reactive and more likely to collide and react with other reactants, thereby increasing the reaction rate and facilitating the experiment and data acquisition. Some hydrogen-rich carbon cycle reactions are endothermic, requiring a certain amount of heat to proceed in the forward direction. Heating hydrogen provides the necessary heat to allow the reaction to reach equilibrium under suitable temperature conditions, which is beneficial for the formation of the target product. If the hydrogen temperature is too low, the reaction may not proceed or the conversion rate may be extremely low, failing to achieve the expected experimental purpose. Heating hydrogen reduces its density and increases its fluidity, allowing it to be more evenly distributed in the reaction apparatus and fully contacting other reactants. This promotes uniform reaction, reduces uneven product distribution caused by uneven local reaction, and improves the accuracy and reliability of experimental results.

[0034] The hydrogen heating and drying gas supply assembly 1 includes a pressure stabilizing tank 11, a gas supply pipe 12, a pressure gauge 13, a motor 14, and a drive shaft 15. The pressure stabilizing tank 11 is fixedly installed on the right side of the heating pipe 10, the gas supply pipe 12 is fixedly installed on the right side of the pressure stabilizing tank 11, the pressure gauge 13 is fixedly installed on the outside of the gas supply pipe 12, the motor 14 is fixedly installed on the front side of the mounting bracket 6, and the drive shaft 15 is fixedly installed on the output end of the motor 14.

[0035] In this embodiment, an air inlet pipe 5 is fixedly installed on the front side of the hydrogen heating box 3, a mounting bracket 6 is fixedly installed on the front side of the air inlet pipe 5, filter plates 7 are fixedly installed on the upper and lower sides of the mounting bracket 6, an air inlet pipe 8 is fixedly installed on the left side of the hydrogen drying box 4, an air outlet pipe 9 is fixedly installed on the right side of the hydrogen drying box 4, and a desiccant pack disassembly and replacement assembly 2 is provided above the hydrogen heating and drying gas supply assembly 1 and the hydrogen drying box 4.

[0036] In this embodiment, the hydrogen heating and drying gas supply assembly 1 further includes a rotating shaft 16, a bevel gear 17, a fan blade 18, a heating resistance wire 19, and a hot gas transmission pipe 20. The rotating shaft 16 is rotatably mounted on the bottom inner wall of the hydrogen heating box 3. The bevel gear 17 is fixedly mounted on the outside of the rotating shaft 16 and the drive shaft 15, with adjacent bevel gears 17 meshing. The fan blade 18 is fixedly mounted on the outside of the rotating shaft 16 and the drive shaft 15 for one circumference. The heating resistance wire 19 is fixedly mounted on the bottom inner wall of the hydrogen heating box 3. The input end of the hot gas transmission pipe 20 is fixedly mounted on the top of the hydrogen heating box 3, and the output end of the hot gas transmission pipe 20 is fixedly mounted on the inner side of the heating pipe 10.

[0037] In this embodiment, the desiccant pack disassembly and replacement assembly 2 includes a first spring 21, a sealing baffle 22, a control rope 23, and a control block 24. The first spring 21 is fixedly installed inside the hydrogen drying chamber 4, the sealing baffle 22 is fixedly installed outside one end of the first spring 21, the control rope 23 is fixedly installed on one side of the sealing baffle 22, and the control block 24 is fixedly installed outside one end of the control rope 23.

[0038] In this embodiment, the desiccant pack disassembly and replacement assembly 2 also includes a desiccant pack placement frame 25 and second springs 26. The desiccant pack placement frame 25 is disposed on the left and right sides inside the hydrogen drying box 4, and multiple second springs 26 are fixedly installed at the bottom of the desiccant pack placement frame 25. An arc-shaped groove is provided on the top of the desiccant pack placement frame 25 to facilitate the removal of the desiccant pack inside the desiccant pack placement frame 25 by the staff.

[0039] In this embodiment, an exhaust pipe 27 is fixedly installed on the outside of the heating pipe 10, and a solenoid valve 28 is fixedly installed on the outside of the exhaust pipe 27. A pressure sensor is installed above the pressure gauge 13, and a regulating valve is installed on the inside of the gas supply pipe 12. The pressure sensor monitors the hydrogen pressure in the buffer tank in real time. A regulating valve is installed above the pressure stabilizing tank 11. The regulating valve can automatically adjust the gas inlet and outlet of the buffer tank. By controlling the gas flow rate and flow, the hydrogen pressure can be precisely adjusted. When the pressure in the buffer tank is too high, the regulating valve reduces the gas inlet or increases the gas outlet. When the pressure is too low, the regulating valve increases the gas inlet or decreases the gas outlet. The pressure sensor and regulating valve are existing technologies, so they are not described in detail in this utility model.

[0040] In this embodiment, storage slots are provided on the top left and right sides of the hydrogen drying box 4. The first spring 21 is fixedly installed on the inner wall of one side of the storage slot, and the sealing baffle 22 is slidably installed on the inner side of the storage slot. The storage slot facilitates the installation of the first spring 21 and allows the sealing baffle 22 to be stored. It also facilitates the removal of the restriction on the desiccant pack placement frame 25 after the sealing baffle 22 slides.

[0041] In this embodiment, a guide groove is provided on the top of the hydrogen drying box 4, and the control rope 23 is slidably arranged inside the guide groove; the guide groove allows the control rope 23 to slide, so that the control rope 23 can drive the sealing baffle 22 to move under force after being pulled, and the control rope 23 is relatively stable during the pulling process.

[0042] Specifically, many hydrogen-rich carbon cycle experiments utilize catalysts. The presence of moisture can occupy the active sites of the catalyst or cause chemical reactions, leading to reduced catalyst activity or even deactivation, thus affecting reaction efficiency and selectivity and causing deviations in experimental results. Therefore, in hydrogen-rich carbon cycle experiments, the supplied hydrogen needs to be heated and dried. The drying operator pulls the control block 24, causing the control rope 23 to be stressed. The control rope 23 moves the sealing baffle 22. After the sealing baffle 22 slides into the receiving trough, the desiccant pack placement frame 25 loses its restraint and can be ejected by the second spring 26 below, facilitating the removal and replacement of the desiccant packaging inside the desiccant pack placement frame 25. After replacement, the desiccant pack placement frame 25 is pressed into the inner side of the hydrogen drying chamber 4. The first spring 21 moves the sealing baffle 22, which restrains the desiccant pack placement frame 25 and controls the hydrogen drying chamber 4. The sealed inlet pipe 8 transmits hydrogen gas to the inside of the hydrogen drying chamber 4. At this time, the heating resistance wire 19 can be started, controlling the motor 14 to drive the drive shaft 15 and fan blades 18 to rotate. After the fan blades 18 rotate, outside air enters and is heated by the heating resistance wire 19. The warmer air inside the hydrogen heating chamber 3 heats the hydrogen drying chamber 4, thus heating the hydrogen gas inside the hydrogen drying chamber 4. The hydrogen gas can be discharged from the outlet pipe 9 on one side. Hydrogen gas is introduced into the inner side of the pressure stabilizing tank 11. A pressure sensor is installed above the pressure gauge 13 to monitor the hydrogen pressure in the buffer tank in real time. A regulating valve is installed above the pressure stabilizing tank 11. The regulating valve can automatically adjust the gas inlet and outlet of the buffer tank. By controlling the gas flow rate and flow, the hydrogen pressure can be precisely regulated. When the pressure in the buffer tank is too high, the regulating valve reduces the gas inlet or increases the gas outlet; when the pressure is too low, the regulating valve increases the gas inlet or decreases the gas outlet.
