Description

Technical Field

[0001] The invention relates to the field of reactors, in particular to a temperature-controlled reactor. Background Art

[0002] Chemical reactor is a kind of equipment used for chemical reaction, which is widely used in the chemical industry. Existing reactors are equipped with temperature control devices to control the temperature in the reactor so that the chemical reaction can be carried out at a suitable temperature to adjust the chemical reaction speed and product quality. However, the temperature control effect of the existing reactor temperature control device is poor during operation, and the temperature control speed is slow. It is difficult to quickly make the reactor reach the appropriate temperature, which is easy to affect the processing efficiency and product quality. In addition, during the heating or cooling process of the reactor, the heat is easily dissipated into the surrounding environment, which will cause heat loss and affect the processing quality of the reactor. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a temperature-controlled reactor in order to overcome the defects of the reactor in the prior art, such as poor temperature control effect, slow temperature control speed and influence on processing efficiency and quality.

The inner shell is used to accommodate reactants, and the interlayer is arranged on the outer surface of the inner shell. The temperature control device includes a accommodating chamber for accommodating a temperature-controlling liquid. The accommodating chamber is connected to the interlayer. The temperature control device can drive the temperature-controlling liquid in the accommodating chamber to flow into the interlayer, and accelerate the flow of the temperature-controlling liquid in the interlayer through the stirring of the stirring device, so that the temperature-controlling liquid in the interlayer quickly reaches a suitable temperature, and then changes the temperature of the inner shell to reach a suitable temperature, so that the reaction in the inner shell can be carried out at a suitable temperature, thereby improving processing efficiency and product quality.

[0040] The temperature control device 200 includes a heating device 220 and a cooling device 230. A heater 221 is provided in the heating device 220, and the heater 221 is used to heat the temperature control liquid. A refrigerator 231 is provided in the cooling device 230, and the refrigerator 231 is used to cool the temperature control liquid. The accommodating chamber 210 of the heating device 220 and the accommodating chamber 210 of the cooling device 230 are respectively connected to the interlayer 120. When the temperature in the reactor body 100 is too low, the temperature control liquid heated by the heating device 220 can flow into the interlayer 120 to increase the temperature of the interlayer 120. When the temperature in the reactor body 100 is too high, the temperature control liquid cooled by the cooling device 230 can flow into the interlayer 120 to reduce the temperature of the interlayer 120. Whether the reaction temperature in the inner shell 110 is too high or too low, it can be adjusted to a suitable temperature by the temperature control device 200, achieving precise temperature control and improving the temperature control effect. In this embodiment, the heater 221 and the refrigerator 231 are respectively arranged below the heating device 220 and the cooling device 230, and are separated from the cavity containing the temperature-controlled liquid by a partition.

When the temperature of the reactor body 100 is too high, the temperature control liquid with a higher temperature in the interlayer 120 can be firstly led out to the transition device 240, and then the temperature control liquid with a lower temperature cooled by the cooling device 230 can be introduced into the interlayer 120, and the temperature control liquid is used to absorb the heat of the reactor body 100 to achieve cooling, and at the same time, the temperature control liquid in the interlayer 120 is stirred by the stirring device 130, so that the temperature control liquid with a lower temperature flows in the interlayer 120, so that the inner shell 110 of the reactor body 100 is quickly cooled, and the temperature control liquid is introduced into the transition device 240 after absorbing the heat, until the temperature in the inner shell 110 reaches a suitable temperature. Similarly, when the temperature of the reactor body 100 is too low, the temperature-controlling liquid with a lower temperature in the interlayer 120 can be first led out to the transition device 240, and then the temperature-controlling liquid with a higher temperature heated by the heating device 220 can be led into the interlayer 120. The transition device 240 plays the role of temporarily storing the temperature-controlling liquid, making the temperature control more flexible and accurate. The heating device 220 and the cooling device 230 are connected to the transition device 240 respectively. When the reactor body 100 is finished working, the temperature-controlling liquid in the interlayer 120 can be led into the transition device 240, and then the temperature-controlling liquid in the transition device 240 can be led back to the heating device 220 and the cooling device 230, so that the temperature-controlling liquid can be reused.
