[0002] In the chemical, pharmaceutical, food and other industries, reactors are common equipment used for various chemical reactions. Circulating water heat exchangers are very important components in reactors, which are used to control the temperature during the reaction and ensure that the reaction can proceed smoothly.

[0003] The heat exchange tube is the core component of the circulating water heat exchanger, which is responsible for transferring heat from one medium to another. However, the heat exchange tube is often easily corroded and contaminated by the external environment during operation, which not only affects the heat exchange efficiency, but also may shorten the service life of the equipment. Although some heat exchangers are equipped with protective covers on the outside of the heat exchange tube, these protective covers are often fixedly connected to the heat exchanger body and are not easy to disassemble, which makes it very inconvenient to maintain and clean the heat exchange tube. Therefore, we propose a circulating water heat exchanger for a reactor. Utility Model Content

[0036] By providing the cleaning scraper 11, the residues and dirt on the inner wall of the reactor 1 can be effectively removed by using the cleaning scraper 11, thereby ensuring the cleanliness of the reactor 1 and providing a good environment for subsequent chemical reactions.

[0037] Working principle: the operator lifts up the fixed card column 15, and the upward movement of the fixed card column 15 will compress the spring 16.
