Problems solved by technology
Due to the large space in the interlayer, the large area of the medium flow channel, and the slow flow rate, this heating method is easy to form a short circuit in the flow channel, resulting in a heat transfer blind zone, and the heat transfer effect is poor.
Moreover, the reactor and the interlayer are fixed, and the reactor cannot be taken out, so it is difficult to clean the reactor
In addition, there is also a method of heating with a water bath or an oil bath. Put the reactor into water or oil to heat it. The reactor is in direct contact with water or oil, especially when the oil bath is used for heating. At the same time, dripping oil or water from the reactor also affects the cleanliness of the operating platform environment

Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0015] Such as figure 1 As shown, Embodiment 1 provides a chemical reaction device, which includes a reaction vessel 11 and a heating jacket 14 .
[0016] The reaction vessel is used to provide a place for a chemical reaction in which to complete the chemical reaction. The reaction container can be a reaction kettle, or other reaction containers, such as test tubes and other containers suitable for completing relevant chemical reactions. Preferably, a stirring device 12 may also be provided in the reaction container for stirring during the chemical reaction.
[0017] The structure of the heating jacket 14 is as figure 2 shown. The heating jacket 14 includes a heating jacket 21 and a heating inner jacket 22 . Both th...

The invention discloses a chemical reaction apparatus, comprising a heating sleeve and a reaction container; the heating sleeve is of sleeve structure and comprises an outer heating sleeve and an inner heating sleeve; the inner heating sleeve and the outer heating sleeve are fixed to each other and are hermetically arranged; the inner heating sleeve has an inner surface and an outer surface; the outer surface of the inner heating sleeve is provided with a plurality of connected circular channels forming a heating flow passage; the reaction container is releasably disposed in the inner heating sleeve and is supported by the heating sleeve, and the reaction container is attached to the inner surface of the inner heating sleeve. By providing the separate heating sleeve and reaction container, it is convenient to change and wash the chemical reaction container; by using the heating sleeve of such a structure, it is possible to improve heating efficiency and keep sufficient supporting force for the reaction container without deformation.
Description
technical field [0001] The invention belongs to the mechanical field, and relates to a chemical reaction device and a temperature control method for the device. Background technique [0002] During the chemical reaction, a reaction kettle is needed to carry out the chemical reaction. The temperature in the reactor needs to be controlled during the chemical reaction, and the precise control of the temperature in the reactor determines the quality of the product output in the reaction to a large extent. [0003] The traditional reactor heating method generally adopts the sandwich heating method, that is, the reactor wall is designed as a hollow sandwich structure with an inlet and outlet. Heat-conducting oil medium, the heat-conducting oil fills the interlayer and flows out from the outlet, and the heat-conducting oil in the interlayer completes the heating of the reactor. Due to the large space of the interlayer, the large area of the medium flow channel, and the slow flo...
