[0002] The reactor is a typical main reaction equipment in today's chemical production. It mainly disperses and mixes various materials through stirring, heating, cooling and other steps to achieve the function of reaction polymerization. The Chinese utility model patent, authorization announcement number "CN219540271U" discloses a high-efficiency dual heat exchange system reactor device. The utility model has the advantage of being able to quickly exchange heat inside and outside the reactor through the cooperation of high and low temperature integrated machines, jackets, heat exchange tubes, connecting tubes and elbows, and then quickly adjusts the reaction temperature of the materials inside the reactor, effectively preventing the temperature from exceeding the set reaction temperature range, improving the accuracy and stability of the reaction, and improving the practicality of the device.

[0003] Although the above technical solution can dissipate heat for the reactor during use, since the heat exchange tubes are directly exposed to the inside of the reactor, when the reactor is stirring the materials, the materials are easily attached to the heat exchange tubes and are difficult to clean. The residues inside the reactor will not only affect the heat exchange efficiency of the reactor, but may also have an adverse effect on the subsequent reaction process and even lead to a decrease in product quality. Therefore, we propose a reactor with a heat exchange device. Utility Model Content
