5L glass reactor thermal oil heating system
5L glass reactor is a common laboratory equipment used for various chemical reactions. In order to ensure that the reaction is carried out at the required temperature, it is usually necessary to equip it with a heating system. Thermal oil (also known as heat transfer fluid or heat carrier) is one of the commonly used heat transfer media because it has good thermal stability and high specific heat capacity.
Main components of thermal oil heating system:
Heater: • Electric heater: usually uses resistance heating method, which can provide stable heating power.
• Heating tube or heating plate: choose the appropriate form according to specific needs.
Circulation pump: • Used to circulate the thermal oil between the heater and the reactor to ensure uniform heat transfer. • The flow rate of the pump should match the needs of the reactor. For a 5-liter reactor, the flow rate is usually around 10-30 L/min.
Thermal oil: • Choose the right thermal oil to ensure that it has good thermal stability and fluidity within the required temperature range. • Common thermal oils include mineral oil, synthetic oil (such as PAO) and silicone oil.
Temperature control system: • PID controller: realizes precise temperature control and adjusts the heating power through a feedback control system. • Temperature sensor: installed at key positions of the reactor and heater to monitor the temperature in real time.
Safety protection device: • Over-temperature protection: automatically cuts off the power supply when the temperature exceeds the set value. • Over-pressure protection: prevents the system pressure from being too high. • Leak detection: detects whether the system has leaks. • Emergency stop button: quickly stop the system in an emergency.
System composition:
- Heater: • Provides a heating source, such as an electric heating jacket, oil bath heater, etc.
- Circulation pump: • Circulates the heat transfer oil between the heater and the reactor to ensure uniform heat transfer. 3. Temperature sensor: • Real-time monitoring of the temperature in the reactor, and feedback of the data to the PID controller.
- PID controller: • Automatically adjusts the heating power according to the set temperature value and the actual measured value to achieve precise temperature control.
- Safety protection device: • Including over-temperature protection, over-pressure protection, leakage detection, etc., to ensure the safe operation of the system.
Summary The selection of the heat transfer oil heating system for the 5L glass reactor should be determined according to the specific experimental requirements and temperature range. Electric heating jackets, oil bath heating, electric heating plates/electric heating tables, etc. are all common heating methods, while heat transfer oil provides good heat transfer performance and temperature control capabilities. Through reasonable selection and configuration, it can ensure that the reaction is carried out under ideal temperature conditions and improve the reliability and repeatability of the experiment.
