Cooling Heating Systems for Glass Reactor

Cooling heating systems are mainly used for temperature control of glass reactors. They can be used to realize the processes of sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc. of the reactors in terms of refrigeration, heating, constant temperature, evaporation, etc.

Features of glass reactor cooling heating systems

Cooling heating systems are devices that realize multiple program temperature control of reactors. They can quickly heat or cool the jacket volume of reactors to reach the required temperature range. There are many types of cooling heating systems, with large, medium and small options. They are reasonably configured with various internal components and external accessories, so they are easy to operate, have good heat dissipation, high refrigeration efficiency and quiet operation.

Working principle and characteristics of glass reactor cooling heating systems

1. By changing the control set value through cooling heating systems, the system lag in the process can be responded to as quickly as possible to obtain a small system overshoot.

2. The control consists of two sets of PID (each set of PID is variable) control loops. These two sets of control loops are called: main loop and slave loop. The control output of the main loop is used as the set value of the slave loop.

3. The system uses a feedforward PV. The output of the PID operation result of the main control loop is combined with the feedforward PV signal as the set value of the slave control loop. By controlling the temperature change gradient in this way, the temperature control accuracy of the system is guaranteed.

4. The specially designed hysteresis predictor (model-free self-building tree algorithm) generates a dynamic signal yc(t) that replaces the process variable y(t) as a feedback signal.

5. Generate an e(t) signal for the controller, so that the controller predicts that the control action has no large lag, so that the controller can always generate a suitable control signal.

6. Combine the tree algorithm with the general anti-hysteresis cascade algorithm through three-point sampling (material temperature point, temperature control system outlet temperature, temperature control system inlet temperature).

Advantages of glass reactor cooling heating systems

1. Users can get a closed and repeatable temperature control in a wide temperature range, which can achieve temperature control of -120℃～350℃;

2. It avoids the need to replace traditional equipment and facilities and maintain the jacket; the smaller fluid volume also ensures that the control loop responds quickly and the thermal reaction delay is very small;

3. The built-in electric heating heat transfer oil auxiliary system can automatically start the auxiliary heating system according to demand and reduce the steam use pressure;

4. Energy saving can be achieved by quickly running the ratio of each heat demand;

5. The temperature of the entire reaction process is controlled by fast calculation, and the exothermic and endothermic reactions in the entire reaction process are quickly responded to and controlled;

6. A standardized interface is reserved, and the cold and heat source heat exchange module can be added according to actual needs;

7. The reaction process temperature and the single fluid temperature can be selected to control, and the temperature difference between the reaction process temperature and the heat transfer single fluid temperature can be set and controlled;

8. Formula management and production process records can be performed.
