Heating and Cooling Devices for Jacketed Reactors

The application of heating and cooling devices in jacketed reactors is a key component for achieving efficient and controllable chemical reaction processes. In the design of jacketed reactors, there is a cavity between its outer wall and the internal reaction chamber, which is the jacket layer. Through this jacket layer, heating media (such as hot water, steam) or cooling media (such as cold water, freezing liquid) can flow to heat or cool the materials in the reactor to achieve precise temperature control. The following are several key points for the application of heating and cooling devices in jacketed reactors:

1. Heating device:

Steam heating: often connected to the steam pipeline, using saturated steam or superheated steam as the heating source, suitable for reactions that require rapid heating and high temperature requirements.

Electric heating: heat is provided by electric heating elements installed in the jacket, such as electric heating wires or far-infrared heaters, which is suitable for scenarios with high temperature control requirements and low heating power.

Hot water circulation: using a hot water circulation system, driving hot water to circulate in the jacket through a pump, suitable for reactions that require gentle heating.

2. Cooling device:

Cold water circulation: Through the cold water circulation system, cooling water is introduced into the jacket for circulation to take away the reaction heat. It is suitable for situations where rapid cooling or low temperature reaction conditions are required.

Refrigeration liquid circulation: When a lower cooling temperature is required, the refrigerated liquid after refrigeration by the freezer can be circulated to achieve the purpose of deep cooling.

Semiconductor refrigeration: For small-scale applications or applications with extremely high temperature control accuracy, a semiconductor temperature control system may be directly attached to the surface of the reactor to achieve precise temperature control.

Temperature control: In order to accurately control the internal temperature of the reactor, an automatic control system is usually equipped, which combines a temperature sensor to monitor the temperature of the reaction medium in real time and automatically adjusts the flow and temperature of the heating or cooling medium to maintain the set temperature point. PID controller is one of the most commonly used temperature control strategies.

Safety measures: The heating and cooling systems are also equipped with safety devices, such as over-temperature protection, pressure relief valve, low liquid level alarm, etc., to ensure the safety of the operation process.

Through the integrated application of the above devices and technologies, the jacketed reactor can effectively cope with the strict requirements for temperature control in various chemical reactions, ensuring reaction efficiency and product quality.
