In the chemical industry, the flow rate of the reactor temperature control system can be customized.
According to the user's requirements, the low temperature and the cooling capacity, the low temperature and the container capacity can be reasonably matched to meet the actual needs of different users; the main function of the reactor temperature control system is to The temperature of the reaction kettle is controlled to improve the heat transfer efficiency, which can meet the strict requirements of high process standards, closed-loop heating, small heat loss, and wide application range
.
Principle of TCU Reactor Temperature Control System In the chemical industry, the reactor is the key to the entire chemical industry, and temperature cooling has become the condition required for the reaction, which is related to the production quality of the entire finished product
.
The reactor temperature control system is selected by the cooling coil, which is equipped with cooling inlet and outlet, cooling water, refrigerant and external circulating coolant
.
Regarding the orientation of the device for cooling the coils, the device is usually inside the reactor to reduce the temperature of the material in the reaction, and can be placed outside when the material is viscous or the coil requires a mixed mode: in the case of the medium used as a heating heat source, the cooling The coil can be placed in the medium, the heating of the resistance wire depends on the specific situation, but the heating effect and cooling effect should be considered
.
The temperature control system of the reactor adopts a high-intelligence PLC and PC-level microcomputer control system, which can be operated remotely, with automatic loading and unloading, timing switch machine and failure cause analysis, real-time recording and display of data, and plotting curve graphs, data are automatically saved
.
Control mode of TCU reactor temperature control system (1) Temperature control mode: The temperature control mode can be divided into position control, proportional control, proportional integral control, proportional derivative control, proportional integral derivative control, PLC and other computer intelligent control, online non-contact temperature control,
etc.
(2) Position control: Position control is that when the temperature of the given value is higher than the set value, the heater is turned off, and when the lower limit temperature is lower than the set value, the heater is turned on, and the temperature is always within a certain range.
The control system is simple and reliable, and is generally used in conduction or convection heating applications
.
(3) Cascade control: Bit control and proportional control When the load changes greatly, it is difficult to maintain its temperature at the set value.
To achieve this, we can add one or more sensors.
When the temperature has not changed, the power can be adjusted in time to ensure the stability of the temperature
.
(4) Online non-contact temperature control: This control method is mainly used in other occasions such as online detection and control of the process temperature of moving objects (such as online control of the working temperature of rolling objects and displacement objects)
.
Selection of working conditions of TCU reactor temperature control system 1.
Select the circulating pump model according to the required volume of coolant.
Of course, the larger the capacity, the lower the temperature, and the higher the price
.
2.
According to the different temperatures required by the experiment, the cryopump with the corresponding temperature control range is selected
.
The lower the temperature, the higher the price of the pump, and the low temperature of the temperature control system of the reactor can reach -120℃
.
3.
Whether the experimental solution is corrosive, if it is a strong acid/alkali type solution, you need to purchase a corrosion-resistant reaction kettle temperature control system
.
Details that need to be paid attention to when selecting accessories for the temperature control system of the TCU reactor: ① When selecting the thermal insulation material, the temperature range of the reactor temperature control system should be considered first, and flame retardant materials must be selected.
The suitable temperature range of the thermal insulation material should include the temperature of the equipment.
The thermal insulation material package of the temperature control system of the reactor should be sufficient, otherwise the equipment control may not achieve the expected effect
.
② When the temperature control system of the reactor is connected to the controlled equipment, pay attention to the connection of the pipeline, the liquid outlet corresponds to the liquid inlet, and the liquid inlet is connected to the liquid outlet.
The water inlet corresponds to the water outlet, and the liquid discharge port (used when replacing the heat transfer medium) corresponds to the waste liquid recovery and collection port
.
③ When selecting pipelines, if inappropriate/damaged hoses and/or hose joints are used, it will cause injury to personnel.
The reactor temperature control system should be careful when configuring its own pipelines such as metal thermal insulation hoses.
Refer to its equal pressure and overpressure capability, caliber, suitable temperature range
.
④ It is necessary to consider the head pressure of the circulating pump inside the equipment.
It is recommended that the temperature control system of the reactor should choose pipes with good quality and sufficient diameter, such as seamless steel pipes
.
⑤ The pipeline connection between the temperature control system of the reactor and the controlled object should be as short as possible to reduce bending.
The possibility of high temperature and low temperature heat transfer medium spraying will cause the possibility of personnel explosion, scald, frostbite and ignition of flammable substances; the possibility of pollution, property damage, and even personal poisoning caused by the loss of reactants
.
