Abstract
The utility model discloses a temperature control device for purified iodine reaction kettles, and the temperature control device comprises a PLC (programmable logic controller) and electric heaters, wherein the top and bottom of a reaction kettle are connected with the electric heaters, the top of the reaction kettle is provided with a thermocouple thermometer, heat transfer tubes of the electric heaters are respectively connected with the upper and lower parts of the reaction kettle, a connecting pipe is provided with a thermocouple thermometer, and the thermocouple thermometer is connected with the PLC through a signal line. According to the utility model, the temperature of the reaction kettle is controlled by using four thermocouple thermometers, so that the whole-process monitoring on the inlet and outlet temperatures of the reaction kettle is ensured; and according to the changes of the inlet and outlet temperatures, the PLC controls the starting and stopping of inlet and outlet heaters, the control can be performed by grouping and determined according to temperature situations, and if the inlet temperature is too high, a group of heaters can be locked, so that the automation control is realized, and the temperature control accuracy is high.
Description
Technical field
The utility model relates to refining iodine production equipment temperature control equipment, especially a kind of refining Iod R still temperature control equipment.
Background technology
At present refining iodine is to purify by thick iodine to obtain, the method of purifying has a lot, different process equipments requires different, and technological parameter is also different, but don't work what Methods For Purification allusion quotation, temperature control precision is all very important, in traditional iodine was produced, simple measurement mechanism commonly used and manual operations were difficult to guarantee temperature control precision, cause product yield low, and loss is large.
Summary of the invention
The utility model aims to provide a kind of refining Iod R still temperature control equipment, to improve the temperature of reaction kettle control accuracy, improves refining iodine output.
A kind of refining Iod R still temperature control equipment, comprise PLC controller and electric heater, connect electric heater at reactor top and bottom, at the reactor top thermocouple thermometer is set, the heat transfer pipe of electric heater connects with the reactor upper and lower respectively, and at duct coupling thermocouple thermometer being set, thermocouple thermometer connects with the PLC controller by holding wire.
Adopt said apparatus, the iodine of not purification is delivered into reactor after, heater, as heat medium, the thermocouple thermometer detected temperatures flows to the PLC controller to these signals to electric heater with oil, the many groups of PLC controller control control heater reaches the purpose of control temperature with this.
The utility model utilizes four thermocouple thermometers that the temperature of reactor is controlled, guaranteed the complete monitoring of reactor entrance and exit temperature, and according to the variation of entrance and exit temperature, the start and stop of PLC controller control entrance and exit heater can divide into groups to control, and decide according to temperature conditions, inlet temperature is too high, can one group of heater of locking, realize automation control, the control temperature accuracy is high.
Description of drawings
Fig. 1 is the utility model structural representation;
In the accompanying drawing: 1 reactor, 2 electric heaters, 3 thermocouple thermometer 4PLC controllers.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, one of them electric heater 2 is by heat transfer pipe and reactor 1 top attachment, another electric heater 2 connects by the upper and lower of heat transfer pipe with reactor 1 one sides, and at reactor 1 top thermocouple thermometer 3 is set, also at the heat transfer duct coupling thermocouple thermometer 3 is set, thermocouple thermometer 3 connects with PLC controller 4 by holding wire, utilize like this four thermocouple thermometers that the temperature of reactor is controlled, guaranteed the complete monitoring of reactor 1 entrance and exit temperature, temperature control precision is high, and the output of refining iodine is just high.
