A corrugated pipe heat exchange device for electrolytic cell energy saving and consumption reduction

Abstract

This application provides an energy-saving and consumption-reducing corrugated tube heat exchanger for an electrolytic cell, relating to the technical field of heat exchanger devices. It includes an outer shell and side shells. Side shells are fixedly connected to both the upper and lower sides of the outer shell, and conduits are fixedly connected to each side shell. Two fixed plates are symmetrically fixedly connected to the upper and lower parts of the inner cavity of the outer shell. Several circular shells are concentrically fixed between the two fixed plates, and several corrugated heat exchange tubes are arranged on both sides of each circular shell. Electrolyte is input into the side shells through the lower conduit, and as the electrolyte is continuously input, it enters the corrugated heat exchange tubes through the circular tubes. Because the outer wall of the corrugated heat exchange tube is corrugated and the overall structure is spiral, the contact area between the corrugated heat exchange tube and the coolant can be effectively increased, improving the heat exchange efficiency of the electrolyte inside the corrugated heat exchange tube, stabilizing the electrolyte system, and achieving energy saving and consumption reduction.

Description

Technical Field

[0001] This application relates to the field of heat exchange device technology, and in particular to a corrugated tube heat exchange device for energy saving and consumption reduction in electrolytic cells. Background Technology

[0002] In the electrolysis industrial production process, the electrolytic cell, as the core reaction equipment, continuously generates a large amount of heat during its operation. If this heat cannot be dissipated in a timely and efficient manner, the internal temperature of the electrolytic cell will rise, which will not only disrupt the stability of the electrolyte system and affect the rate of the electrolysis reaction and the purity of the products, but also increase the energy consumption in the electrolysis process.

[0003] Currently, the industry primarily uses traditional straight-tube heat exchangers to meet the heat exchange requirements of electrolytic cells. The outer surface of a straight-tube heat exchanger is a regular cylindrical structure. Within the limited heat exchange space of the electrolytic cell, the effective heat exchange area per unit volume is small. This restricts the contact area between the coolant and the high-temperature medium inside the electrolytic cell, resulting in a slow heat transfer rate. This makes it difficult to quickly and fully dissipate the heat generated by the electrolytic cell, leading to low heat exchange efficiency and increased energy consumption. Furthermore, existing straight-tube heat exchangers often have integrally arranged heat exchangers. When the coolant flows within the heat exchanger tubes, some areas experience excessively high flow rates, resulting in insufficient contact time with the inner wall of the heat exchanger tube and inadequate heat absorption. Conversely, some areas experience excessively slow flow rates or even stagnation, leading to localized overheating of the heat exchanger tube in those areas. This significantly reduces the overall heat exchange efficiency. This uneven coolant distribution further diminishes the heat exchange effect.

[0004] Based on the above reasons, this utility model proposes a corrugated tube heat exchange device for energy saving and consumption reduction in electrolytic cells. This device effectively increases the heat exchange area, optimizes coolant distribution, and significantly improves heat exchange efficiency, thereby reducing energy consumption and consumption in electrolytic cells. Utility Model Content In view of the above problems, this application provides a corrugated tube heat exchange device for energy saving and consumption reduction in electrolytic cells, so as to solve the problem of low heat exchange efficiency of existing heat exchange devices.

[0005] This application provides an energy-saving and consumption-reducing corrugated tube heat exchange device for an electrolytic cell, including an outer shell. Side shells are fixedly connected to both the upper and lower sides of the outer shell, and conduits are fixedly connected to each side shell. Two fixed plates are symmetrically fixedly connected to the upper and lower parts of the inner cavity of the outer shell. Several circular shells are concentrically fixedly connected between the two fixed plates. Several corrugated heat exchange tubes are arranged on both sides of each circular shell. The corrugated heat exchange tubes are arranged in a spiral and circumferential array. A circulation pipe is fixedly connected to the side of the fixed plate away from the center of the outer shell.

[0006] In some embodiments, the circulation tube includes a fixed tube, which is L-shaped and concentric with the fixed plate. The two ends of the fixed tube pass through the fixed plate and the side shell, respectively. A plurality of connecting tubes are evenly distributed and fixedly connected to the fixed tube. A plurality of vertical tubes are fixedly connected to the connecting tubes. The connecting tubes and the vertical tubes both pass through the fixed plate and are located on both sides of the circular shell.

[0007] In some embodiments, both ends of the corrugated heat exchange tube are fixedly connected to round tubes, and the ends of the round tubes away from the corrugated heat exchange tubes pass through the fixing plates on both sides and are fixedly connected to the fixing plates.

[0008] In some embodiments, flange plates are fixedly connected to both sides of the outer casing, and flange plates are fixedly connected to the side of the side shell facing the outer casing. Adjacent flange plates are fixedly connected by bolts and nuts.

[0009] In some embodiments, sealing rings are fixedly connected to one side of each of the two flange plates facing each other.

[0010] In some embodiments, both the outer shell and the fixing plate have circular cross-sections, and the inner diameter of the outer shell is the same as the diameter of the fixing plate.

[0011] Through the above scheme, the electrolyte is introduced into the side shell through the lower conduit. As the electrolyte is continuously introduced, it enters the corrugated heat exchange tube through the circular tube. Because the outer wall of the corrugated heat exchange tube is corrugated and the whole is spirally designed, the contact area between the corrugated heat exchange tube and the coolant can be effectively increased, thereby improving the heat exchange efficiency of the electrolyte in the inner cavity of the corrugated heat exchange tube, stabilizing the electrolyte system, and achieving the effect of energy saving and consumption reduction. The coolant is introduced into the connecting pipe and the vertical pipe through the lower fixed pipe, so that the coolant is distributed into each circular shell. The separation of the circular shells allows the coolant to have full contact with the corrugated heat exchange tubes, thereby optimizing the coolant distribution, improving the heat exchange efficiency, further improving the stability of the electrolyte system, and achieving the effect of energy saving and consumption reduction.

[0022] like Figures 1-5 As shown, this application embodiment provides an energy-saving and consumption-reducing corrugated tube heat exchange device for an electrolytic cell, including an outer shell 1. Side shells 2 are fixedly connected to both the upper and lower sides of the outer shell 1. Flange plates 12 are fixedly connected to both sides of the outer shell 1. Flange plates 12 are fixedly connected to the side of the side shells 2 facing the outer shell 1. Adjacent flange plates 12 are fixedly connected by bolts 13 and nuts 14. By connecting the side shells 2 and the outer shell 1 together, the fixed installation between the side shells 2 and the outer shell 1 can be achieved by using bolts 13 and nuts 14. Furthermore, sealing rings 15 are fixedly connected to one side of each of the two flange plates 12 facing each other, which can effectively improve the sealing between the outer shell 1 and the side shell 2 and improve the stability of the heat exchange device. A conduit 3 is fixedly connected to each side shell 2. Two fixed plates 4 are fixedly connected symmetrically to the inner cavity of the outer shell 1. Several circular shells 5 are fixedly connected concentrically between the two fixed plates 4. Several corrugated heat exchange tubes 6 are provided on both sides of the circular shells 5. The corrugated heat exchange tubes 6 are arranged in a spiral and circumferential array. Circular tubes 11 are fixedly connected to both ends of the corrugated heat exchange tubes 6. The end of the circular tube 11 away from the corrugated heat exchange tube 6 passes through the fixed plates 4 on both sides and is fixedly connected to the fixed plates 4. In the technical solution of this embodiment, during use, the electrolyte is input into the side shell 2 from the lower conduit 3. As the electrolyte is continuously input, it enters the corrugated heat exchange tube 6 through the circular tube 11. Because the outer wall of the corrugated heat exchange tube 6 is corrugated and the whole is spirally arranged, it can effectively increase the contact area between the corrugated heat exchange tube 6 and the coolant, and allow the electrolyte after heat exchange to be discharged from the conduit 3 on the top surface of the upper side shell 2, thereby improving the heat exchange efficiency of the electrolyte in the inner cavity of the corrugated heat exchange tube 6, stabilizing the electrolyte system, and achieving the effect of energy saving and consumption reduction. Furthermore, both the outer shell 1 and the fixing plate 4 have circular cross-sections, and the inner diameter of the outer shell 1 is the same as the diameter of the fixing plate 4, which facilitates the separation of coolant and electrolyte. A circulation pipe 7 is fixedly connected to the side of the fixed plate 4 away from the center of the outer shell 1. The circulation pipe 7 includes a fixed pipe 8, which is L-shaped and concentric with the fixed plate 4. The two ends of the fixed pipe 8 pass through the fixed plate 4 and the side shell 2 respectively. Several connecting pipes 9 are evenly distributed and fixedly connected to the fixed pipe 8. Several vertical pipes 10 are fixedly connected to the connecting pipes 9. The connecting pipes 9 and the vertical pipes 10 pass through the fixed plate 4 and are located on both sides of the circular shell 5 respectively. In this embodiment, during use, coolant is introduced from the lower fixed pipe 8 into the connecting pipe 9 and the vertical pipe 10, so that the coolant is distributed into each of the circular shells 5. The separation of the circular shells 5 allows the coolant to fully contact the corrugated heat exchange tubes 6 inside, and the coolant after heat exchange enters the upper fixed pipe 8, connecting pipe 9 and vertical pipe 10, and is discharged uniformly from the upper fixed pipe 8, completing the circulation of coolant. This achieves the effect of improving heat exchange efficiency by optimizing coolant distribution, further improving the stability of the electrolyte system, and achieving the effect of energy saving and consumption reduction.
