Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a spiral threaded tube bundle heat exchanger. Background Technology

[0002] The spiral threaded tube heat exchanger is a new type of high-efficiency and energy-saving heat exchange equipment. Its design completely breaks through the traditional shell-and-tube heat exchanger design concept. From material selection to structural form and external volume, it has undergone significant changes compared with the traditional shell-and-tube heat exchanger. Multiple technological innovations have enabled this heat exchanger to significantly surpass the traditional shell-and-tube heat exchanger in terms of appearance and performance. It has changed the characteristics of traditional heat exchangers, such as simple structure, large size, rough appearance and low efficiency. It is a replacement product for traditional heat exchangers.

[0003] For example, the spiral threaded tube bundle shell and tube heat exchanger disclosed in patent number 201821974007.3 is easy to descale. It does not require disassembling the heat exchanger tube body to clean the threaded tube bundle, saving time and manpower. However, the above structure cannot effectively wet the tube bundle during use, which makes it unable to perform effective auxiliary heat exchange and cleaning, thus reducing its heat exchange efficiency and working efficiency. Therefore, we propose a spiral threaded tube bundle shell and tube heat exchanger. Utility Model Content

A moist sponge that fits against the first threaded tube bundle and the second threaded tube bundle is fitted inside the ring body.

[0008] According to the spiral threaded tube bundle heat exchanger, a threaded hole is provided on the side wall of the annulus near the top, and a lead screw is sleeved in the threaded hole. The left and right ends of the lead screw pass through the threaded hole and are movably connected to the side walls of two piston blocks through bearings. A servo motor is bolted to the left side wall of the left piston block near the top, and the left end of the lead screw passes through the inner ring of the bearing and is connected to the output shaft of the servo motor.

[0022] Reference Figures 1 to 4This utility model discloses a spiral threaded tube bundle shell-and-tube heat exchanger, comprising: a heat exchanger tube body 1, with cover plates 2 movably connected to both the left and right sides of the heat exchanger tube body 1. An externally threaded tube 12 is bolted to the side of the cover plate 2 opposite to the heat exchanger tube body 1, and an internal thread matching the externally threaded tube 12 is formed on the inner wall of the heat exchanger tube body 1. Piston blocks 16 are slidably connected to both the left and right sides of the heat exchanger tube body 1, and a main tube body 15 is connected between the two piston blocks 16.

A first left inlet pipe 5 is connected to the left side of the first threaded tube bundle 13 near the top, and a first right inlet pipe 3 is connected to the right side of the first threaded tube bundle 13 near the bottom. The second threaded tube bundle 14 is connected to the left side of the second threaded tube bundle 14 near the bottom. The bottom is connected to a second left inlet pipe 7, and the right side of the second threaded tube bundle 14 is connected to a second right inlet pipe 6 near the top. The side wall of the piston block 16 on the left is connected to a cooling water inlet pipe 8 that is connected to the main body 15, and the side wall of the piston block 16 on the right is connected to a cooling water outlet pipe 4 that is connected to the main body 15. The first left inlet pipe 5, the second left inlet pipe 7 and the cooling water inlet pipe 8 extend to the outside of the left cover plate 2. The second right inlet pipe 6, the first right inlet pipe 3 and the cooling water outlet pipe 4 extend to the outside of the left cover plate 2. The top of the heat exchanger tube body 1 is connected to a liquid injection pipe 10 near the left and right sides, and the bottom of the heat exchanger tube body 1 is connected to a drain pipe 9 near the left and right sides. Both the liquid injection pipe 10 and the drain pipe 9 are fitted with sealing plugs 11.

[0023] The first threaded tube bundle 13 and the second threaded tube bundle 14 are fitted with the same ring 17. The top and bottom of the ring 17 are slidably connected to the top and bottom of the inner cavity of the heat exchanger tube body 1, respectively. A slider is bolted to the bottom of the ring 17, and a groove matching the slider is provided at the bottom of the inner cavity of the heat exchanger tube body 1. A moistened sponge 18, which fits against the first threaded tube bundle 13 and the second threaded tube bundle 14, is fitted inside the ring 17.
