Description

Technical Field

[0001] This application relates to the field of heat exchangers, and more particularly to heat exchangers with insulated sleeves. Background Technology

[0002] Currently, ammonia coolers and heat exchangers are widely used in the synthetic ammonia industry. In the synthetic ammonia process, to condense gaseous ammonia into liquid ammonia, the process gas temperature needs to be cooled to -10°C. Ammonia, due to its high latent heat, suitable operating pressure and specific volume, stable chemical properties, and non-decomposition at high temperatures, is readily available in synthetic ammonia plants. Therefore, ammonia is widely used as a refrigerant in the synthetic ammonia industry to provide cooling for the condensation of gaseous ammonia in the process gas. The 26°C process gas is cooled to -10°C by the ammonia cooler, then goes to the ammonia separator to separate the condensed liquid ammonia. After the liquid ammonia is removed, the -10°C process gas goes to the heat exchanger to cool the 37°C hot gas, recovering cooling capacity and reducing energy consumption. The 37°C hot gas is then cooled to 26°C before entering the ammonia cooler.

[0003] Existing combined heat exchangers are prone to internal contamination with impurities during actual use, so they need to be cleaned regularly. However, the heat exchangers currently in use are inconvenient to disassemble and reassemble, which affects the regular maintenance of the heat exchangers. Utility Model Content

One side of the outer wall of the connecting cover 9 is provided with an air port, and the outer wall of the flange 10 is provided with multiple equally spaced mounting ports 11, and the mounting ports 11 are matched with the connecting mechanisms 8.

[0033] In use, flange 7 is provided on the outer shell 1. The flange 7 facilitates the installation of the connecting mechanism 8. The cooperation between the connecting mechanism 8 and flange 10 facilitates the quick assembly and disassembly of the connecting cover 9 on the outer shell 1, thereby enabling the quick assembly and disassembly of the connecting cover 9 and facilitating the cleaning and maintenance of the heat exchange elements in the outer shell 1. A sealing ring is provided between flange 7 and flange 10, which improves the sealing performance between the connecting cover 9 and the outer shell 1.

[0034] Reference Figure 2-3 The connecting mechanism 8 includes a fixed seat 14 fixedly connected to the flange 7, and a T-shaped sliding shaft 17 slidably connected to the inner wall of the fixed seat 14. A connecting component 18 is installed at one end of the sliding shaft 17. A screw 16 is rotatably connected to one side of the inner wall of the fixed seat 14. A threaded hole is opened at one end of the sliding shaft 17. One end of the screw 16 is screwed into the inner wall of the threaded hole. A rotating part 15 is rotatably connected to one side of the outer wall of the fixed seat 14, and one end of the drive shaft of the rotating part 15 is fixedly connected to the screw 16. The connecting component 18 can be easily installed through the sliding shaft 17 on the fixed seat 14. The sliding of the sliding shaft 17 can easily drive the movement of the connecting component 18. The rotation of the rotating part 15 drives the screw 16 to rotate. When the screw 16 rotates, it can easily drive the sliding shaft 17 to slide in the fixed seat 14.

[0035] Reference Figure 3-4The connecting assembly 18 includes a connecting seat 19 fixedly connected to the sliding shaft 17, and a rotating column 21 rotatably connected to one outer wall of the connecting seat 19. Openings are provided on both inner walls of the connecting seat 19, and T-shaped limiting blocks 20 are slidably connected to the inner walls of both openings. The same screw 22 is rotatably connected to both inner walls of the connecting seat 19, and a trapezoidal block 23 is screwed to the outer wall of the screw 22. Slide grooves are provided on both outer walls of the trapezoidal block 23, and wedge plates 2 are slidably connected to the inner walls of both slide grooves. 4. One end of each of the two wedge plates 24 is fixedly connected to the two limit blocks 20. One end of the drive shaft of the rotating column 21 is fixedly connected to the screw 22. The rotating column 21 drives the screw 22 to rotate. When the screw 22 rotates, it directly drives the trapezoidal block 23 to move. When the trapezoidal block 23 moves, it cooperates with the wedge plates 24 to drive the two limit blocks 20 to move. The setting of the connecting seat 19 facilitates the sliding installation of the two limit blocks 20. The setting of the limit blocks 20 facilitates the installation of the auxiliary connecting seat 19 on the flange 10.

[0036] Reference Figure 1-3 The outer wall of the outer shell 1 is fixedly connected to four symmetrically arranged exhaust pipes 1-2, and all four exhaust pipes 1-2 are connected to the outer shell 1. The outer wall of the outer shell 1 is fixedly connected to a liquid injection pipe 3. The outer wall of the outer shell 1 is fixedly connected to an exhaust pipe 2-4, which is connected to the outer shell 1. The outer wall of the outer shell 1 is fixedly connected to an exhaust pipe 3-5, which is connected to the outer shell 1. The outer wall of the outer shell 1 is fixedly connected to an air inlet pipe 1-6, which is connected to the outer shell 1. The inner wall of the outer shell 1 is fixedly connected to multiple equally spaced partitions 12, and the outer wall of the partitions 12 has multiple equally spaced through holes. Multiple heat exchange pipes 13 are fixedly connected between the multiple partitions 12. The multiple through holes on the partitions 12 facilitate the passage of gas through the partitions 12.

The arrangement of the liquid injection pipes 3 facilitates the injection of liquid ammonia. The arrangement of the exhaust pipes 2-4 facilitates the discharge of heated air. The arrangement of the exhaust pipes 3-5 facilitates the discharge of cold air.

[0037] The implementation principle of the heat exchanger with insulated sleeve in this embodiment is as follows: During use, the heat exchange tube 13 in the outer shell 1, in conjunction with the cooling zone on the heat exchanger, facilitates the cooling or heating of the gas or liquid entering the outer shell 1. When the outer shell 1 operates for a long time, the heat exchange elements in the outer shell 1 need to be cleaned. During cleaning, the connecting cover 9 needs to be disassembled. When disassembling the connecting cover 9, the rotating part 15 is first rotated by a wrench. When the rotating part 15 rotates, it directly drives the screw 16 to rotate. When the screw 16 rotates, it drives the sliding shaft 17. When the sliding shaft 17 moves, it facilitates the movement of the connecting assembly 18. When the connecting assembly 18 moves away from the flange 2 10, the flange 2 10 can be released. When the connecting assembly 18 passes through the mounting port 11 on the flange 2 10, the rotating column 21 drives the screw 22 to rotate. When the screw 22 rotates, it drives the trapezoidal block 23 to move towards the rotating column 21. The movement of the trapezoidal block 23 cooperates with the wedge plate 24 to pull the limiting block 20 into the connecting seat 19. At this time, the connecting seat 19 can be pulled out from the flange 2 10, thereby realizing the disassembly of the connecting cover 9.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
