Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a titanium heat exchanger with composite titanium tubes. Background Technology

[0002] Titanium heat exchangers are widely used in many fields such as chemical industry, power generation, and seawater desalination due to their strong corrosion resistance and high heat transfer efficiency. The working principle of titanium heat exchangers is to use high-quality titanium tubes as heat exchange elements to transfer part of the heat of the hot fluid to the cold fluid, thereby realizing heat exchange.

[0003] A search revealed a patent, CN210664052U, which discloses a titanium heat exchanger with composite titanium tubes. The heat exchanger includes a connecting perforated plate, a heat medium inlet, a baffle assembly, and a cold water outlet. A filter screen is located in the middle of the heat medium inlet, and a heat medium inlet chamber is located on one side of the heat medium inlet. A connecting perforated plate is located on the side of the heat medium inlet chamber furthest from the heat medium inlet. This invention reduces heat loss from the heat exchanger shell by installing an insulation cylinder on the outside of the heat exchanger, ensuring excellent heat exchange performance. It avoids the need to increase the amount and temperature of the heat medium due to excessive heat loss, thus saving raw materials. Furthermore, the invention features a conveniently detachable baffle assembly, with the baffles arranged in a modular form, making the assembly and disassembly of the first and second combined plates easier and faster. An adsorbent filter rod is located in the middle of the baffles, allowing impurities after cold water heat exchange to be adsorbed promptly, preventing impurities from adhering to the titanium tubes and reducing heat exchange efficiency.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In reality, due to prolonged heat exchange operations, impurities from the heat exchange medium will adhere to the inside of titanium heat exchange tubes. Over time, this will reduce the overall heat exchange efficiency of the heat exchange device. Therefore, there is an urgent need in the field to improve titanium heat exchangers with composite titanium tubes to overcome the shortcomings of existing technologies. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7A titanium heat exchanger with composite titanium tubes includes a first housing 1, a second housing 2 fixedly installed at one end of the first housing 1, a heat exchange box 3 for heat exchange inside the first housing 1, a refrigerant inlet 4 and a refrigerant outlet 5 communicating with the heat exchange box 3 on the side of the first housing 1, a heat medium outlet 6 at the end of the first housing 1 away from the second housing 2, a heat medium separation hood 10 at the end of the heat exchange box 3 near the second housing 2, a heat medium inlet 7 communicating with the inside of the heat medium separation hood 10 at the side of the end of the second housing 2 near the first housing 1, a plurality of titanium heat exchange tubes 8 and staggered baffles 9 inside the heat exchange box 3, a movable plate 11 adapted to the heat exchange box 3 inside the second housing 2, a plurality of connecting rods 12 adapted to the titanium heat exchange tubes 8 fixedly installed on one side of the movable plate 11, and a perforated scraper 13 adapted to the inner cavity of the titanium heat exchange tubes 8 fixedly installed at the end of the connecting rods 12. The second housing 2 is equipped with a drive unit for driving the moving plate 11 to move back and forth. A filter unit for filtering impurities is provided at the position of the heat medium inlet 7. The drive unit includes two fixed seats 14 symmetrically fixedly installed in the second housing 2. Two symmetrical moving seats 15 are fixedly installed on the side of the moving plate 11. The fixed seats 14 have moving grooves 16 adapted to the moving seats 15 on their side. A drive screw 26 threadedly connected to the moving seat 15 is rotatably connected in the moving groove 16. A drive motor 17 for driving the drive screw 26 to rotate is fixedly installed at one end of the fixed seat 14. The filter unit includes a detachable connecting pipe 18 fixedly installed at one end of the heat medium inlet 7 through a mounting flange. A filter medium placement frame 19 is provided in the detachable connecting pipe 18. The filter medium placement frame 19 contains the filter medium. Several through holes 20 are opened through the side of the filter medium placement frame 19 near the second housing 2.

[0030] Specifically, when using this device for heat exchange, the heat medium inlet 7 is used to transport the heat medium, which enters the heat medium separation hood 10 and is dispersed into several titanium heat exchange tubes 8, and then discharged through the heat medium outlet 6. The cold medium inlet 4 is used to input the cold medium into the heat exchange box 3, and it flows within the heat exchange box 3 with the cooperation of the baffle 9, and then is discharged through the cold medium outlet 5, completing the entire heat exchange process. When the heat medium enters, it first passes through the detachable connecting pipe 18, and the filter medium placement frame 19 inside the detachable connecting pipe 18 is filled with filter medium to filter the heat medium. The filtered heat medium has fewer internal impurities, preventing them from entering the titanium heat exchange tube 8 and causing damage. During heat exchange, two synchronous drive motors 17 are activated. The output of the drive motors 17 drives the drive screw 26 to rotate. When the drive screw 26 rotates, it drives the moving seat 15 to slide in the moving groove 16. The two moving seats 15 drive the moving plate 11 to move, the moving plate 11 drives the connecting rod 12 to move, and the connecting rod 12 drives the hollow scraper 13 to move. The hollow scraper 13 is hollow and does not affect the transmission of the heat medium. The scraper 13, with its surface abutting against the inner wall of the titanium heat exchanger tube 8, moves reciprocally to clean the inner wall of the titanium heat exchanger tube 8, preventing impurities from adhering to it. The movement frequency can be determined based on actual conditions, such as starting at regular intervals (e.g., every few hours), to maintain the optimal heat exchange effect of the titanium heat exchanger tube 8 and improve the overall heat exchange efficiency of the heat exchange device. The side of the scraper 13 can be made of polytetrafluoroethylene (PTFE), which has excellent chemical stability, hardly reacts with any chemical substances, and is corrosion resistant. It is extremely strong and can remain stable in harsh environments such as strong acids, strong alkalis and strong oxidants. Moreover, it has a very low coefficient of friction and a smooth surface, which reduces friction with the titanium heat exchanger tube 8 when cleaning the inner wall of the titanium heat exchanger tube 8, thus reducing wear on the titanium heat exchanger tube 8. At the same time, impurities are not easily attached to its surface, making it easy to clean. In addition, polytetrafluoroethylene has good temperature resistance and can be used in a wide temperature range. The above-mentioned filter media can be activated carbon plates or fiber filter media, etc., which can achieve the filtration effect, and the choice is determined according to the actual situation.

[0031] As a technical optimization of this utility model, a number of plug-in strips 21 are fixedly installed on the side of the filter medium placement frame 19. A number of plug-in grooves 22 adapted to the plug-in strips 21 are opened on the inner side wall of the detachable connecting pipe 18. The plug-in grooves 22 penetrate one side of the detachable connecting pipe 18. The filter medium placement frame 19 is inserted into the plug-in grooves 22 on the inner side wall of the detachable connecting pipe 18 through the plug-in strips 21 on its side. The detachable connecting pipe 18 is installed through a flange, which facilitates the replacement of the filter medium. When the filter medium is granular, a cover plate can be added to the open end of the filter medium placement frame 19. The cover plate is also provided with through holes 20.

[0032] As a technical optimization of this utility model, the hollow scraper 13 has several through-holes 23, and the sides of the through-holes 23 have rounded chamfers. The through-holes 23 are used for the passage of heat medium. The hollow scraper 13 has an elastic friction ring 24 on its side. The elastic friction ring 24 is elastic and has a cleaning effect on the inside of the titanium heat exchange tube 8. The elastic friction ring 24 is made of polytetrafluoroethylene (PTFE). The middle position of the hollow scraper 13 can be made of a suitable metal material. The hollow scraper 13 has a mounting groove 25 on its side. The mounting groove 25 is used to embed and install the elastic friction ring 24. When the elastic friction ring 24 is damaged, the elastic friction ring 24 can be replaced without replacing the entire hollow scraper 13, thus reducing costs.
