TCU temperature control system USES the existing heat (such as steam, cooling water and cryogenic liquid - the "primary") system infrastructure are integrated into the single fluid system was used to control the temperature of process equipment or in the secondary loop.This achieves only one type of heat transfer liquid can flow into the jacket of the reaction vessel (not directly flow into steam, cooling water or ultra-low temperature liquid).The temperature of the whole reaction process is controlled by operation.

Reactor Temperature System ZLF Has the following advantages:

A. The user can obtain a closed and repeatable temperature control at a wide temperature range, which can achieve the temperature control of -120 degrees ~ 300 degrees;
B. Avoid the replacement of traditional equipment and the requirement for jacket maintenance;The smaller fluid volume also guarantees the quick response of the control loop and the thermal response delay is small.
C. The built-in electric heating oil auxiliary system can automatically turn on the auxiliary heating system according to the requirements to reduce the steam pressure;
D. can achieve the energy saving purpose by fast running accurate matching of each heat demand;
E. Control the temperature of the whole reaction process by accurate and fast operation, and the rapid response control is carried out during the whole reaction process.
F. There is a standardized interface, which can increase the heat transfer module according to the actual demand;
G. the temperature of the control reaction process and the single fluid temperature can be selected, and the temperature difference between the temperature of the reaction process and the temperature of the thermal conductivity can be controlled.
H. can carry out recipe management and production process record.

Full closed pipe design is adopted.According to the instructions given by the system PLC, turn on the Angle of the electric control valve and control the flow of the cryogenic liquid into the reactor jacket, thus achieving energy saving and efficiency.All the signals in this process are based on temperature. To ensure the safety operation of the system, electric hair can be fully opened by hand.



Principle of TCU temperature control system

Use area: can be used in various explosion-proof areas

The temperature control unit (TCU) is mainly used in reactor heating, cooling temperature control in fine chemical, chemical pharmaceutical, and biopharmaceutical processes. It can realize automatic control of temperature rise, temperature drop, constant temperature and distillation during the reaction process, especially suitable for the reaction process. There is a process control that requires heat and heat.

When the TCU temperature control unit is in high-efficiency operation, it must pay attention to timely protection and maintenance. If the equipment is actively handled under the condition that the equipment is subject to defects, the service life of the equipment will become longer.

Users can get a closed and repeatable temperature control over a wide temperature range, temperature control from -120 to 300 °C; avoid the need for replacement of traditional equipment and jacket maintenance; smaller fluid volume is also guaranteed The control loop reacts quickly and the thermal reaction delay is small. Built-in electric heating and heat conduction and auxiliary system, can be automatically opened according to demand, reducing steam pressure. The device has a standardized interface, which can increase the heat source heat exchange module according to actual needs.

The TCU device opens the angle of the electric regulating valve according to the instruction given by the system PLC, and controls the flow rate of the low temperature liquid into the reaction jacket jacket, thereby achieving energy saving and high efficiency. All signals fed back by this process are based on temperature.

LNEYA's TCU temperature control system principle:

1. The method of changing the control set value can respond to the system lag in the process as soon as possible, and get a small system overshoot. Control consists of two sets of PIDs (each group of PIDs are variable) control loops;
2. A specially designed lag predictor (no model self-built tree algorithm) generates a dynamic signal yc(t) instead of the process variable y(t) as a feedback signal. Generating an e(t) signal to the controller to cause the controller to predict that the control action has no large hysteresis, so that the controller can always generate a suitable control signal;

3. Through three-point sampling (material temperature point, temperature control system outlet temperature, temperature control system inlet temperature), through our company's own model-free self-built tree algorithm and general anti-lag cascade algorithm.
