The structure of jacketed heat exchanger

Date:2018-10-19

Structure: Jacketed heat exchanger is mainly used for heating or cooling of the reaction process, and is made by installing a jacket on the outer wall of the container.

The jacketed heat exchanger is a kind of a partition type heat exchanger, which is made by installing a jacket on the outer wall of the container, and has a simple structure; however, the heating surface is limited by the wall surface of the container, and the heat transfer coefficient is not high. In order to increase the heat transfer coefficient and make the liquid in the kettle heat evenly, a stirrer can be installed in the kettle. When the jacket is filled with cooling water or a phase change-free heating agent, a spiral partition or other may be arranged in the jacket. Increase the turbulence measures to increase the heat transfer coefficient on one side of the jacket. In order to supplement the shortage of the heat transfer surface, a coil can also be installed inside the kettle. Jacketed heat exchangers are widely used for heating and cooling of the reaction process.

The jacketed heat exchanger is mainly used in the reactor, and is installed outside the reactor to form a closed interlayer to allow fluid to enter the interlayer and exchange heat with the material in the reactor through the wall. The structure of the jacketed heat exchanger is relatively simple, and the heat exchange can be performed while the material reacts, thereby eliminating the trouble of separately providing the heat exchange equipment.
