Description

Technical Field

[0001] The utility model belongs to the technical field of spiral wound heat exchangers, and particularly relates to an anti-vibration structure for the lead-out section of the spiral wound tube of a spiral wound heat exchanger. Background Technique

[0002] The spiral wound heat exchanger is a heat exchange device widely used in industrial production. The application prospect of the spiral wound heat exchanger is very broad. First of all, with the country's high attention to environmental protection and energy conservation, as an efficient and energy-saving heat exchange device, the spiral wound heat exchanger is more and more recognized and favored by the market. Especially in industrial fields such as petroleum, chemical industry, and metallurgy, its application has become one of the main means to promote the adjustment of the energy structure and the promotion of green transformation and upgrading. Secondly, the spiral wound heat exchanger can be applied to the heat exchange between various media, such as steam-water, water-oil, air-water, air-gas, etc., and has a wide application prospect in different industrial fields. In addition, the spiral wound heat exchanger has a long service life, a simple structure, convenient maintenance, and a lower use cost than other heat exchange devices, so it also has more advantages in the market.

[0003] The working principle of the spiral wound heat exchanger is mainly based on the heat transfer between the fluid inside the pipe and the fluid outside the pipe. Specifically, it directly exchanges heat between the internal fluid and the external fluid through a spiral tube with a smaller inner diameter of the pipe and a fixed tube with a larger outer diameter of the pipe. The internal fluid is generally a liquid or a gas, while the external fluid is cooling water or steam. When the internal fluid flows in the spiral tube, the heat it carries will be conducted through the pipe wall to the outer surface of the fixed tube, and then dissipated through the absorption of the external fluid, so as to achieve heat exchange.

[0004] In order to increase the fluid flow rate, the spiral wound heat exchanger adopts a structure of multiple spiral wound tubes and increases the number of spiral wound tubes. However, under the vibration condition of the spiral wound heat exchanger, the lead-out sections of the multiple spiral wound tubes vibrate and become loose, which in turn leads to the problem of damage to the spiral wound tubes, affecting the normal use of the spiral wound heat exchanger. For this reason, we propose an anti-vibration structure for the lead-out section of the spiral wound tube of a spiral wound heat exchanger. Content of the Utility Model

[0008] Preferably, there is one annular metal strip, and the annular metal strip is arranged on the outer side of the lead-out section of the outermost winding pipe.
