Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen cooling, in particular to hydrogen cooling equipment for hydrogen preparation. Background Art

[0002] Hydrogen is a colorless, odorless gas with a lower density than air and poorly soluble in water. It is one of the most important industrial gases and special gases. At room temperature and pressure, hydrogen is a highly flammable, colorless, transparent, odorless and poorly soluble gas. Due to its flammable nature, for safety reasons, it needs to be cooled during the storage process during preparation to slow down the chemical reaction rate and reduce the risk of leakage.

[0003] At present, when preparing and storing hydrogen, the existing storage tank has a single structure and does not have the function of cooling the internal hydrogen in real time, which causes the internal temperature to change uncontrollably under the influence of the external environment, which is prone to safety hazards;

[0004] In order to solve the above problems, the present application proposes a hydrogen cooling device for hydrogen preparation. Utility Model Content

[0005] The purpose of the utility model is to provide a hydrogen cooling device for hydrogen preparation, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a hydrogen cooling device for hydrogen preparation, comprising: a storage tank, which is an annular tank body with a smooth outer wall; a folding ring tube adapted to different covering areas is arranged on the outer side of the storage tank, and sealing rings for sealing the gap between the storage tank and the folding ring tube are arranged at the upper and lower ends of the folding ring tube, and the folding ring tube and the sealing ring cooperate to form an annular hollow cavity for conveying cold water for temperature reduction and cooling treatment; ring seats for installing sealing rings are arranged on the outer sides of the upper and lower ends of the storage tank, and an extrusion block for extruding the sealing ring to clamp the storage tank for easy installation and maintenance is arranged on the inner side of the ring seat.

[0008] Furthermore, a protruding rubber strip is provided at one end of the sealing ring, and a positioning groove for snap-fitting connection with the rubber strip is provided on the inner side of the ring seat.

[0009] Furthermore, a shrinkage belt for driving the extrusion block to tighten the sealing ring is sleeved on the outer side of the ring seat, and a drawstring for controlling the tightness is passed through the inside of the shrinkage belt.

[0010] Furthermore, a water pipe for conveying cooling water is arranged on the outer side of the ring seat, in a bottom-cooling and top-heating flow mode.

[0011] Furthermore, a protruding limiting protrusion is arranged on the outer side of the contraction belt, and a protruding tube for installing a drawstring is arranged on the outer side of the limiting protrusion.

[0012] Furthermore, a side groove for docking with the extrusion block is provided on the outer side of the sealing ring.

[0013] Furthermore, a connecting plate for mounting a folding ring tube is provided on one side of the sealing ring, and a guide groove for guiding cooling water for easy emptying is provided on the upper end of the sealing ring.

[0014] The utility model has the following beneficial effects:

[0015] After the hydrogen is stored in the storage tank, the utility model forms an annular hollow cavity outside the storage tank by using the cooperation of the sealing ring and the folding ring tube. At this time, cooling water is directly poured into the water pipe to form a flow, which can take away the heat of the hydrogen and the storage tank to form a cooling effect. Compared with the existing storage mechanism, it can effectively improve the safety of hydrogen storage, reduce safety hazards and improve the use effect of the equipment;

[0016] The utility model utilizes the pulling of a pull rope to extrude the sealing ring through the extrusion block so that it can be closely attached to the outer wall of the storage tank. The extrusion force forms a seal and a fixing effect at the same time. At this time, the folding ring tube is directly unfolded and the covering area is adjusted according to the external structure of the storage tank. After this arrangement, the cooling component can be conveniently assembled and disassembled, which improves the applicability and facilitates maintenance, replacement and use at any time.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-5 As shown, the utility model is a hydrogen cooling device for hydrogen preparation, comprising: a storage tank 1, the storage tank 1 is an annular tank body with a smooth outer wall;

[0029] The outer side of the storage tank 1 is provided with a folding ring tube 3 adapted to different coverage areas, and the upper and lower ends of the folding ring tube 3 are provided with sealing rings 4 for sealing the gap between the storage tank 1 and the folding ring tube 3. The folding ring tube 3 and the sealing ring 4 cooperate to form an annular hollow cavity to transport cold water for cooling treatment;

[0030] Ring seats 2 for installing sealing rings 4 are arranged on the outer sides of the upper and lower ends of the storage tank 1, and extrusion blocks 6 for squeezing the sealing ring 4 to clamp the storage tank 1 for easy installation and maintenance are arranged on the inner side of the ring seat 2;

[0031] The present embodiment provides a storage cooling mechanism after hydrogen preparation, which utilizes an annular cavity to transport cooling water so that it flows from bottom to top, and removes the heat of the storage tank 1 and the hydrogen inside it in real time, so as to achieve the effect of cooling and reducing safety hazards. At the same time, the installation method of the mechanism is simple and it can be repaired and replaced at any time. Secondly, the foldable ring tube 3 can cover various areas outside the storage tank 1, which is highly applicable and easy to use.

[0032] Among them, a protruding rubber strip 5 is provided at one end of the sealing ring 4, and a positioning groove 11 for the rubber strip 5 to be snap-connected is opened on the inner side of the ring seat 2. The rubber strip 5 adopts an elastic rubber mechanism and expands outward when the external force is small, so that it can be stably installed inside the positioning groove 11.

[0033] Among them, the outer side of the ring seat 2 is provided with a shrinkage belt 7 which drives the extrusion block 6 to tighten the sealing ring 4. A pull rope 9 for controlling the tightness is passed through the inside of the shrinkage belt 7. The shrinkage of the shrinkage belt 7 is used to clamp the sealing ring 4 in all directions to prevent uneven force from affecting the sealing effect.

[0034] Among them, a water pipe 8 for conveying cooling water is arranged on the outside of the ring seat 2. It is a cold-bottom and hot-top flow mode. Cold water is filled into the water pipe 8 located at the bottom. As the water level continues to rise, the temperature of the cooling water in the upper area gradually rises, and then it is discharged outward through the water pipe 8 located at the top to take away the heat.

[0035] Among them, a protruding limiting protrusion 15 is provided on the outside of the shrinkage band 7, and a convex tube 10 for installing the pull rope 9 is provided on the outside of the limiting protrusion 15. A hole for passing the pull rope 9 is opened inside the limiting protrusion 15, and one end of the hole is a closing mechanism for installing one end of the pull rope 9 to fix it.

[0036] The outer side of the sealing ring 4 is provided with a side groove 12 for docking the extrusion block 6, through which the extrusion block 6 is used to prevent deflection.

[0037] Among them, a connecting plate 13 for installing the folding ring tube 3 is provided on one side of the sealing ring 4, and a guide groove 14 for guiding cooling water for easy emptying is opened on the upper end of the sealing ring 4, so that the water can be quickly pumped out when the cooling mechanism is disassembled, which is convenient for assembly and disassembly operations.

[0038] It can be understood that the utility model can take away a large amount of heat by cooling the surface of the storage mechanism in real time, preventing the internal temperature from rising steadily to reduce safety hazards. Secondly, the installation structure of the mechanism is simple, which is convenient for installation and disassembly, use, maintenance and replacement.

[0039] A specific application of the operation process of this embodiment is as follows: when in use, first insert the sealing ring 4 into the interior of the ring seat 2 so that the rubber strip 5 is engaged with the interior of the positioning groove 11 to form a connection, then directly sleeve it on the outside of the storage tank 1 and make the folding ring tube 3 unfold outward to cover the outer shell of the storage tank 1, further pull the drawstring 9 to shrink the shrinkage belt 7, thereby driving the extrusion block 6 to squeeze the sealing ring 4 inward so that the inner side surface is tightly fitted to the outer surface of the storage tank 1, forming a sealing effect. At the same time, the reverse force during clamping can be used to fix the ring seat 2 to the outer side of the upper and lower ends of the storage tank 1, and then cold water is transported through the water pipe 8 and flows upward, and finally flows out through the water pipe 8 located above to take away the heat of the storage tank 1 and the hydrogen inside it, forming a cooling effect, and improving the safety performance of the equipment. The cooling component has a simple structure and can be assembled and disassembled at any time, which is convenient for installation and use and is also conducive to subsequent maintenance and other processing.
