Description

Technical Field

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

[0002] In the fields of new energy and chemical engineering, methanol-to-hydrogen technology has become one of the important technological routes for industrial-grade hydrogen production due to its advantages such as the wide availability of methanol as a raw material, convenient transportation and storage, and clean and efficient hydrogen production process. In methanol-to-hydrogen systems, hydrogen collection relies on dedicated hydrogen storage tanks. These tanks, as the core equipment for temporary hydrogen storage and transfer, must possess excellent sealing, pressure resistance, and safety to adapt to subsequent hydrogen purification, transportation, or direct application processes. Their performance directly affects the operating efficiency and stability of the entire methanol-to-hydrogen system, thus placing high demands on the structural design and functional adaptability of the hydrogen storage tanks.

[0003] In the hydrogen collection process, to increase the hydrogen storage capacity per unit volume of the hydrogen storage tank and meet the high-pressure storage requirements in practical applications, the hydrogen entering the tank needs to be compressed. However, when hydrogen is compressed inside the tank, the intermolecular distance decreases sharply, the frequency of molecular collisions increases significantly, and mechanical energy is converted into internal energy, causing the internal temperature of the tank to rise rapidly. If the heat inside the tank cannot be dissipated in time, on the one hand, the temperature of the tank body will exceed the safety threshold, affecting the mechanical properties of the tank material. Long-term high-temperature environment may lead to fatigue damage to the tank body, reducing the service life and safety factor of the hydrogen storage tank; on the other hand, high temperature will change the physical state of hydrogen, which may lead to a decrease in the actual hydrogen storage capacity inside the tank and increase the risk of hydrogen leakage. Therefore, this application proposes a novel hydrogen collection device to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a novel hydrogen collection device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel hydrogen collection device includes a hydrogen storage tank body. A water-cooled heat dissipation pipe is fitted onto the hydrogen storage tank body. The water-cooled heat dissipation pipe is fixedly fitted onto the hydrogen storage tank body by an arc-shaped fixing plate. The water-cooled heat dissipation pipe consists of a spiral pipe and a connecting pipe. There are two connecting pipes, which are respectively fixedly installed at both ends of the spiral pipe. Several protective supports are fixedly installed in a ring on the outer wall of the hydrogen storage tank body. The protective supports are also fitted onto the outside of the water-cooled heat dissipation pipe. The protective supports consist of an L-shaped support plate and an arc-shaped baffle. There are two L-shaped support plates, which are symmetrically fixedly installed on the inner wall of the arc-shaped baffle.

[0007] Preferably, an inlet pipe is fixedly inserted into the lower side wall of the hydrogen storage tank body, an outlet pipe is fixedly inserted into the upper side wall of the hydrogen storage tank body, and a support leg is fixedly installed at the lower end of the hydrogen storage tank body.

[0008] Preferably, the spiral pipe on the water-cooled heat dissipation pipe is sleeved on the hydrogen storage tank body, and the spiral pipe is in contact with the outer wall of the hydrogen storage tank body. The spiral pipe and the connecting pipe are fixedly connected by welding, and the connecting pipe is connected to the cooling water circulation equipment through a pipe.

[0009] Preferably, two notches are symmetrically provided on the outer walls of the upper and lower sides of the arc-shaped fixing plate. The arc-shaped fixing plate is fixedly installed on the outer wall of the hydrogen storage tank body by bolts. Several arc-shaped slots are provided on the inner end of the arc-shaped fixing plate. The arc-shaped fixing plate is sleeved on the spiral pipe through the arc-shaped slots.

[0010] Preferably, the arc-shaped baffle on the protective bracket is located on the outside of the spiral pipe, and the L-shaped support plate is fixedly connected to the outer wall of the hydrogen storage tank body by bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] A water-cooled heat dissipation pipe system, consisting of a spiral pipe and connecting pipes, is installed on the main body of the hydrogen storage tank. This system is then fixedly connected to the main body via an arc-shaped fixing plate. The spiral pipe is in close contact with the outer wall of the main body. When hydrogen is compressed and heated within the main body, cooling water supplied by the cooling water system can enter the spiral pipe through the connecting pipe, quickly absorbing the heat transferred from the main body to the spiral pipe and circulating it out. This effectively controls the temperature inside the main body within a safe threshold, preventing high temperatures from affecting the mechanical properties of the main body material, preventing fatigue damage, extending the service life of the main body, and ensuring the stability of the physical state of the hydrogen inside the main body. This reduces the risk of hydrogen storage loss and leakage, ensuring the safety and efficiency of the entire hydrogen collection process. A protective bracket consisting of an L-shaped support plate and an arc-shaped baffle is installed on the outside of the water-cooled heat dissipation pipe to protect the spiral pipe, reducing the probability of collisions and preventing damage or leakage due to external impacts, thus ensuring the normal operation of the water-cooled heat dissipation system.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a novel hydrogen collection device includes a hydrogen storage tank body 1. A water-cooled heat dissipation pipe 3 is fitted onto the hydrogen storage tank body 1. The water-cooled heat dissipation pipe 3 is fixedly fitted onto the hydrogen storage tank body 1 by an arc-shaped fixing plate 2. The water-cooled heat dissipation pipe 3 consists of a spiral pipe 8 and two connecting pipes 9, which are respectively fixedly installed at both ends of the spiral pipe 8. Several protective supports 4 are fixedly installed in a ring on the outer wall of the hydrogen storage tank body 1. The protective supports 4 are fitted onto the outside of the water-cooled heat dissipation pipe 3. The protective supports 4 consist of an L-shaped support plate 10 and an arc-shaped baffle 13. Two L-shaped support plates 10 are symmetrically fixedly installed on the inner wall of the arc-shaped baffle 13. By fitting the water-cooled heat dissipation pipe 3, composed of the spiral pipe 8 and connecting pipes 9, onto the hydrogen storage tank body 1 and fixing the water-cooled heat dissipation pipe 3 to the hydrogen storage tank body 1 by the arc-shaped fixing plate 2, wherein the spiral pipe 8 is in close contact with the outer wall of the hydrogen storage tank body 1, when hydrogen... During the compression and heating process within the hydrogen storage tank body 1, the cooling water supplied by the cooling water circulation equipment can enter the spiral pipe 8 through the connecting pipe 9. This rapidly absorbs the heat transferred from the hydrogen storage tank body 1 to the spiral pipe 8 and circulates it out, effectively controlling the temperature within the hydrogen storage tank body 1 within a safe threshold. This prevents high temperatures from affecting the mechanical properties of the hydrogen storage tank body 1 material, prevents fatigue damage to the hydrogen storage tank body 1, extends the service life of the hydrogen storage tank body 1, and ensures the stability of the physical state of hydrogen within the hydrogen storage tank body 1, reducing the risk of hydrogen storage capacity reduction and leakage, and ensuring the safety and efficiency of the entire hydrogen collection process. By installing a protective bracket 4 consisting of an L-shaped support plate 10 and an arc-shaped baffle 13 on the outside of the water-cooled heat dissipation pipe 3, the spiral pipe 8 of the water-cooled heat dissipation pipe 3 can be protected, thereby reducing the probability of the spiral pipe 8 being impacted and preventing damage or leakage caused by external force impacts, ensuring the normal operation of the water-cooled heat dissipation system.

[0020] Specifically, an inlet pipe 5 is fixedly inserted into the lower side wall of the hydrogen storage tank body 1, and an outlet pipe 6 is fixedly inserted into the upper side wall of the hydrogen storage tank body 1. A support leg 7 is fixedly installed at the lower end of the hydrogen storage tank body 1. A spiral pipe 8 on the water-cooled heat dissipation pipe 3 is sleeved on the hydrogen storage tank body 1, and the spiral pipe 8 contacts the outer wall of the hydrogen storage tank body 1. The spiral pipe 8 and the connecting pipe 9 are fixedly connected by welding. The connecting pipe 9 is connected to the cooling water circulation equipment through a pipe. Two notches 12 are symmetrically opened on the outer walls of the upper and lower sides of the arc-shaped fixing plate 2. The arc-shaped fixing plate 2 is fixedly installed on the outer wall of the hydrogen storage tank body 1 by bolts. Several arc-shaped slots 11 are opened at the inner end of the arc-shaped fixing plate 2. The arc-shaped fixing plate 2 is sleeved on the spiral pipe 8 through the arc-shaped slots 11. The arc-shaped baffle 13 on the protective bracket 4 is located outside the spiral pipe 8. The L-shaped support plate 10 is fixedly connected to the outer wall of the hydrogen storage tank body 1 by bolts. When using the hydrogen storage tank body 1 for hydrogen collection, the hydrogen generated by the external hydrogen production equipment is first transported into the hydrogen storage tank body 1 through the gas inlet pipe 5 fixedly inserted on the lower side wall of the hydrogen storage tank body 1. After the hydrogen storage capacity in the hydrogen storage tank body 1 reaches the required level, the control valve on the gas inlet pipe 5 is closed to stop the gas intake. When hydrogen is needed later, the control valve on the gas outlet pipe 6 fixedly inserted on the upper side wall of the hydrogen storage tank body 1 is opened, so that the hydrogen in the hydrogen storage tank body 1 is transported to the designated hydrogen-using equipment through the gas outlet pipe 6. At the same time, throughout the entire use of the hydrogen storage tank body 1, several protective brackets 4 fixedly installed in a ring on its outer wall are always fitted on the outside of the water-cooled heat dissipation pipe 3. The arc-shaped baffle 13 is located on the outside of the spiral pipe 8, which can effectively block the collision that may be caused to the spiral pipe 8 from the outside, reduce the probability of the spiral pipe 8 being damaged or leaking due to external impact, and ensure the structural integrity and normal use of the water-cooled heat dissipation pipe 3.

[0021] Furthermore, when the water-cooled heat dissipation pipe 3, in conjunction with the cooling water circulation equipment connected to it, cools the hydrogen storage tank body 1, the two connecting pipes 9 of the water-cooled heat dissipation pipe 3 are first connected to the external cooling water circulation equipment through the pipes. When the hydrogen gas is compressed inside the hydrogen storage tank body 1, causing the temperature inside the tank to rise, the cooling water circulation equipment is activated. The cooling water circulation equipment delivers cooling water through the lower connecting pipe 9 to the spiral pipe 8 of the water-cooled heat dissipation pipe 3. Since the spiral pipe 8 is fitted on the hydrogen storage tank body 1 and contacts the outer wall of the hydrogen storage tank body 1, the cooling water in the spiral pipe 8 will quickly absorb the heat transferred from the hydrogen storage tank body 1. After absorbing the heat, the cooling water flows back to the cooling water circulation equipment through the upper connecting pipe 9. After being cooled by the cooling water circulation equipment, it is delivered back to the spiral pipe 8. This cycle repeats continuously, carrying away the heat from the hydrogen storage tank body 1, achieving effective cooling of the hydrogen storage tank body 1, and ensuring that the temperature inside the hydrogen storage tank body 1 is controlled within the safe threshold.

[0022] Obviously, the above embodiments are merely illustrative examples for clear explanation 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 here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
