Description

Technical Field

[0001] The utility model relates to the technical field of a fixed reactor with internal moving elements, in particular to a temperature control device for a reactor. Background Art

[0002] A reactor is broadly understood as a container for physical or chemical reactions. The heating, evaporation, cooling and low-speed mixing functions required by the process are achieved through the structural design and parameter configuration of the container. The Chinese utility model patent, authorization announcement number "CN215996642U" discloses a temperature-controlled reactor. By setting a first coil and a second coil, hot water or cold water can be simultaneously introduced into the inside of the first coil and the second coil to determine whether to heat or cool the reactor during use. The first coil and the second coil are welded around the reactor body and can withstand higher pressure with thinner materials, which greatly saves material usage. In addition, the thickness of the steel plate of the reactor body can also be reduced accordingly, which is beneficial to heat exchange, thereby achieving the purpose of rapid heating and cooling of the reactor and increasing the pressure resistance of the reactor.

[0003] Although the above technical solution can control the temperature of the reactor during use, the heat exchange tubes are exposed to the outside or inside of the reactor without any protection, so that the heat exchange tubes outside the reactor are prone to burns to operators, and the heat exchange tubes inside the reactor are easily corroded by materials and difficult to clean. Therefore, we propose a reactor temperature control device. Utility Model Content
