Contact us today for the perfect temperature control solution

Glass reactor is a very important experimental equipment for scientific research and chemical production. The precise control of temperature in glass reactors is even more important. It not only helps improve the efficiency of the device, but also ensures product quality, stable operation of the equipment, and ensures the safety of experimental personnel. The temperature control method of glass reactor is of great significance in actual production.

The glass reactor uses steam, hot water or thermal oil to exchange heat with the materials through the heat exchange device of the reactor to increase the temperature of the materials in the reactor. The temperature measurement in the kettle generally uses a thermal resistor or thermocouple according to the temperature measurement range, and forms a control loop with the regulating valve on the heat transfer medium pipeline entering the reactor to achieve the purpose of temperature regulation.

Conventional reactor temperature control only requires simple PID single-loop adjustment, which mainly includes: controlled object (reactor), detection and transmission device (thermocouple or thermal resistor), control device (DCS) and execution adjustment mechanism ( Regulating valve) four parts. Taking hot water heat transfer medium as an example, when the temperature of the reactor does not reach the set value, the hot water inlet regulating valve is opened wide to fully exchange heat between the hot water and the material. When the set temperature is reached, the hot water inlet regulating valve opens Turn it off to maintain the material temperature at the set value and realize automatic control of the entire reactor temperature.

But for some more complex reaction processes, such as: the reaction kettle needs to be heated first to start the reaction. After the reaction starts, a large amount of heat is released. In order to make the reaction proceed smoothly, the reaction kettle needs to be cooled down. In this case, if you want to realize the startup of the reactor and normal production automation, you must use a split-range control system.

In a simple control system, the output of a regulator only drives one regulating valve. In the split-range control system, the output of one regulator drives two or more regulating valves to work. Each regulating valve only operates within a certain signal range output by the regulator.

When the temperature in the reactor is lower than the set value, the regulator will command the steam inlet valve to open to heat the reactor. When the reaction starts, as the reaction heat is gradually released, the regulator will gradually close the steam inlet valve, and then slowly open the cooling water inlet valve to take away the reaction heat. In this way, the temperature of the reactor can be kept basically unchanged from the start of the reaction in the reactor until the reaction becomes stable, thus achieving the automatic control requirements of the process.

In the chemical production process, the reactor is the main equipment for converting raw materials into products, which is related to the overall production efficiency. For this reason, in order to adapt to the current development needs in the chemical industry, attention should be paid to temperature control issues in the chemical production process and the temperature control system should be designed to enhance the temperature control effect of the reactor and meet the needs of chemical production.
