Description

Technical Field

[0001] The present invention relates to the technical field of cooling of air separation projects, and in particular to a hydrogen refrigeration cooling system for air separation projects. Background Art

[0002] Air separation engineering, or air separation engineering, is the process of separating and purifying air components through specific processes and equipment based on the differences in their physical properties (such as boiling point and bubble point). Specifically, nitrogen, oxygen, and argon in air have different boiling points, making them separable through processes such as distillation. As an important technical project, air separation plays a vital role in modern industrial production and daily life. With the continuous advancement of technology and the expansion of its application areas, air separation engineering will usher in even broader development prospects.

[0003] In air separation projects, some auxiliary equipment (such as compressors, pumps, heat exchangers, etc.) will generate a lot of heat during operation and require effective cooling to ensure their normal operation and extend their service life. Hydrogen refrigeration cooling systems, due to their efficient refrigeration capacity, can be used as one of the cooling systems for these auxiliary equipment, providing low-temperature cooling media to remove the heat generated by the equipment.

[0035] See also Figures 1 to 8 The present invention provides a hydrogen refrigeration cooling system for air separation projects, comprising:

[0036] A fixed frame 1, on the inner wall of its bottom, is fixedly mounted a refrigerator 2, the left side of the refrigerator 2 is connected to a hydrogen storage tank 3, the right side of the refrigerator 2 is connected to a hydrogen cooling assembly 4, the left side of the hydrogen cooling assembly 4 is connected to a hydrogen compressor 5, and the left side of the hydrogen compressor 5 is connected to the hydrogen storage tank 3, and the hydrogen storage tank 3, the hydrogen cooling assembly 4 and the hydrogen compressor 5 are all fixedly mounted on the inner wall of the bottom of the fixed frame 1;

[0037] A control cabinet 6 is fixedly mounted on the side wall on the left side of the fixed frame 1;

[0038] A hydrogen concentration detector 7 is fixedly mounted on the inner wall of the left side of the fixed frame 1;

[0039] A leakage repair assembly 8 is fixedly assembled on the inner wall of the upper end of the fixed frame 1;

[0040] A leakage warning light 9 is fixedly mounted on the upper surface of the fixed frame 1;

[0041] As a preferred embodiment, baffles are provided on the outside of the fixed frame 1, and the device is set as a sealed body to reduce the influence of external conditions. The refrigerator 2, as the core of the system, is responsible for producing low-temperature cooling hydrogen. The hydrogen storage tank 3 contains a medium (hydrogen) circulating in the system, which is used to absorb and take away the heat of the cooled object. The hydrogen cooling component 4 is provided with two circuits, air cooling and water cooling. The appropriate mode can be selected according to the situation to exchange heat with the cooled object, and in the air cooling mode, the hydrogen cooling component 4 can dissipate the heat carrying hydrogen in advance, thereby reducing the working pressure of the device. The concentration detector 7 is used to monitor the operating status of the system at all times to ensure the safe and stable operation of the system and prevent leakage. The occurrence of accidents can be improved, and the safety performance of the device can be improved. The hydrogen compressor 5 can further compress the hydrogen so that it can be at the same pressure as the hydrogen in the hydrogen storage tank 3, thereby avoiding the excessive volume of hydrogen in the cycle from entering the hydrogen storage tank 3 through the water, thereby causing gas accumulation, which will affect the cooling efficiency and bring great safety risks. The leakage repair component 8 can quickly find or eliminate the leakage point when the hydrogen concentration in the device is abnormal, and when there is a leakage point, the leakage repair component 8 can perform repair work, thereby improving work efficiency to a certain extent and reducing the probability of accident risks. The leakage warning light 9 can be used to warn when there is a large leakage point in the device, reminding the staff to perform manual repairs.

[0042] Furthermore, the hydrogen cooling component 4 includes:

[0043] A cooling water tank 41 is provided with two groups of heat sinks 42 vertically arranged in the front and back. A main output pipe 46 is fixedly provided at the lower left end of the two groups of heat sinks 42. The other side of the main output pipe 46 is connected to the refrigerator 2. A connecting output pipe 44 is fixedly provided at the right upper end of the two groups of heat sinks 42. The other end of the connecting output pipe 44 is connected to two groups of heat exchange fans 43 arranged vertically. A booster valve 45 is provided at the connection between the connecting output pipe 44 and the two groups of heat exchange fans 43. The two groups of heat exchange fans 43 are fixedly embedded in the inner wall on the right side of the fixed frame 1.

[0044] A hydrogen return pipe 48 is provided on the other side of the two groups of heat exchange fans 43, and the other end of the hydrogen return pipe 48 is connected to the hydrogen compressor 5;

[0045] As a preferred embodiment, the cooling water tank 41 is filled with cooling water, and is made of a thermal insulation material, which can effectively ensure the temperature of the cooling water therein.

[0046] Furthermore, a connecting reflux pipe 49 is provided on the right side of the upper end of the two groups of heat sinks 42, and the other end of the connecting reflux pipe 49 is connected to the hydrogen reflux pipe 48;

[0047] An auxiliary output pipe 47 is provided between the main output pipe 46 and the connecting return pipe 49 .

[0048] Furthermore, multiple sets of control valves are provided on the main output pipe 46, the connecting return pipe 49, the auxiliary output pipe 47, the connecting output pipe 44 and the hydrogen return pipe 48. By controlling the opening and closing of different control valves, the hydrogen cooling component 4 can be divided into two modes: air cooling and water cooling. When the hydrogen cooling component 4 is in the water cooling mode, an external water cooling device is required.

[0049] As a preferred embodiment, the main output pipe 46, the auxiliary output pipe 47, the connecting return pipe 49, the connecting output pipe 44 and the hydrogen return pipe 48 located outside the cooling water tank 41 and the heat-insulating pipe can effectively prevent the external temperature conditions from affecting the hydrogen inside. The hydrogen return pipe 48 located inside the cooling water tank 41 is made of copper pipe with good thermal conductivity, which can enable the hydrogen to release a certain amount of heat through the cooling water in the cooling water tank 41 during the reflux process, thereby better performing subsequent work. When working, the device will switch the hydrogen cooling component 4 to the water cooling circuit mode through the control cabinet 6, and complete the heat exchange between the low-temperature hydrogen and the cooling water inside it through the heat sink 42, and keep the cooling water inside it at a certain temperature. Then the device will switch the water cooling circuit or the air cooling circuit according to the requirements of the air separation project it serves. It is worth noting that if the device is in the air cooling state, it needs to be switched back to the water cooling circuit periodically to cool the cooling water in the cooling water tank 41.

[0050] Furthermore, the leakage repair assembly 8 includes a horizontal transverse rail 81, and two groups of the horizontal transverse rails 81 are symmetrically provided and fixedly assembled on the inner walls of the front and rear sides of the upper end of the fixed frame 1 respectively. The two groups of the horizontal transverse rails 81 are slidably assembled with transverse sliding blocks 82, and the two groups of the transverse sliding blocks 82 are fixedly assembled with horizontal longitudinal rails 83. The left side of the horizontal longitudinal rail 83 is slidably assembled with a longitudinal sliding block 84, and the left side of the longitudinal sliding block 84 is vertically fixedly assembled with an automatic telescopic plate 85. The lower surface of the automatic telescopic plate 85 is horizontally fixedly assembled with a bearing plate 86, and the lower surface of the bearing plate 86 is fixedly assembled with a detection and repair assembly 87;

[0051] As a preferred embodiment, the setting of the horizontal transverse track 81, the horizontal longitudinal track 83 and the automatic telescopic plate 85 can enable the detection and repair component 87 to reach any position in the device, thereby better performing the detection and repair work.

[0052] Furthermore, the detection and repair assembly 87 includes a drive motor 871, on the output shaft of which a rotating block 872 is fixedly mounted. The rotating block 872 is fixedly mounted with a leakage detector 873 and two sets of pipe clamping claws 874. The leakage detector 873 and the two sets of pipe clamping claws 874 are arranged in a circle, and each set of pipe clamping claws 874 has two sets of clamping claws fixedly mounted with a fixed semicircular rail 875.

[0053] As a preferred embodiment, the rotation of the driving motor 871 can drive the rotating block 872 and the leakage detector 873 and two sets of pipe clamping claws 874 thereon to rotate, thereby adjusting the leakage detector 873 and the two sets of pipe clamping claws 874 so that they can adjust their positions to better perform leakage point detection and repair work.

[0054] Furthermore, two sets of fixed semicircular rails 875 on one set of pipe clamping claws 874 are slidably mounted with two sets of self-driving sliders 876, and a leakage grinder 877 is fixedly mounted on the other side of each set of self-driving sliders 876;

[0055] Of the two sets of fixed semicircular rails 875 on the other set of pipe clamping claws 874, only one set of fixed semicircular rails 875 is slidably mounted with a set of self-propelled sliders 876, and the other side of the self-propelled sliders 876 is fixedly mounted with a Thore carbon nanopolymer material repairer 878;

[0056] As a preferred embodiment, when the pipe clamping claws 874 in the same group are in the clamping state, the two groups of fixed semicircular rails 875 thereon will be combined into a complete circular track, so that the self-driving slider 876 thereon can rotate along the circular track under its own drive, thereby achieving the purpose of cleaning and material repair.

[0057] Furthermore, the leakage grinder 877 includes two groups of hydraulic cylinders 8771, each group of hydraulic cylinders 8771 is fixedly equipped with a fixed block 8772 at the other end, and a rotating shaft is rotatably provided between the two groups of fixed blocks 8772, and a rotating grinding block 8773 is coaxially fixedly equipped on the rotating shaft;

[0058] As a preferred embodiment, the rotating grinding block 8773 can clean and process the pipe surface around the leakage point so as to better bond the repair material, improve the repair quality, and reduce the risk of secondary leakage. The hydraulic cylinder 8771 can adjust the center distance between the rotating grinding block 8773 and the fixed semicircular rail 875, so that it can serve hydrogen pipelines of different diameters, thereby improving the adaptability of the device. The rotational friction coefficient between the rotating grinding block 8773 and the fixed block 8772 can select suitable friction materials before the device is installed, thereby adjusting the friction components of the rotating grinding block 8773 during work, so as to better adapt to different processing requirements.

[0059] Furthermore, the Solei carbon nano-polymer material repairer 878 includes a Solei carbon nano-polymer material tank 8781, a material application head 8783 is fixedly mounted on the other side of the Solei carbon nano-polymer material tank 8781, and a blending material tank 8782 is fixedly arranged between the Solei carbon nano-polymer material tank 8781 and the material application head 8783;

[0060] As a preferred embodiment, Sore carbon nanopolymer material has excellent bonding properties and media resistance, and can specifically solve the problem of hydrogen pipeline leakage. It has good bonding strength, strong media resistance, excellent corrosion resistance and anti-aging performance, and can meet the needs of long-term operation under on-site working conditions. When working, the blending material tank 8782 will blend the Sore carbon nanopolymer material according to the proportion, and then use the material application head 8783 to evenly apply the repair material to the leakage point and its surrounding area to ensure that the leakage point is completely covered. This technology does not require disassembly of the equipment, reducing the difficulty and cost of repair.

[0061] During the specific implementation, the following steps are included: after the refrigerator 2 is started, the hydrogen in the hydrogen storage tank 3 enters the refrigerator 2, and the refrigerator 2 starts to produce low-temperature cooling hydrogen. The hydrogen undergoes a series of physical or chemical changes inside the refrigerator 2, and the temperature gradually decreases. The low-temperature hydrogen is transported to the hydrogen cooling component 4 through a pipeline. The hydrogen cooling component 4 exchanges heat with the cooled object through water cooling or air cooling. The heat of the cooled object is transferred to the cooling medium, thereby achieving cooling. The cooling hydrogen carrying heat will release some heat in the cooling water tank 41 of the hydrogen cooling component 4, and then enter the hydrogen compressor 5. The hydrogen compressor 5 will compress the hydrogen to a certain density, and then pass it into the hydrogen storage tank 3 for recycling. During the operation of the device, the hydrogen concentration The detector 7 will monitor the hydrogen concentration in the device at all times. When it detects that the concentration in the device increases, it will drive the leakage repair component 8 to detect the leakage point through the leakage detector 873 thereon. When the leakage detector 873 detects the specific location of all leakage points, it will control the control cabinet 6 to stop working, and then drive the leakage grinder 877 to grind the leakage point position. After the grinding is completed, the Sorey carbon nanopolymer material repairer 878 will be used for repair. After the repair material solidifies, the repair work is completed and the device is restarted. If the hydrogen concentration detector 7 detects a large change in hydrogen concentration, it means that the leakage point is large. At this time, the control cabinet 6 will be controlled to stop working, and then the leakage warning light 9 will be controlled to turn on to remind the staff to perform manual repairs.

[0062] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
