Application Cases in the Chemical Industry
In the production workshop of a large - scale chemical enterprise, various chemical synthesis reactions are mainly carried out, and the reaction kettle is the core equipment. To ensure the safety of the reaction process and the stability of product quality, the enterprise has equipped the reaction kettle with a comprehensive industrial sensor monitoring system.
Temperature sensors are installed inside the reaction kettle and in the jacket area. The internal temperature sensor can accurately measure the real - time temperature of the materials in the reaction kettle, with a measurement accuracy of up to ±0.5°C. The temperature sensor in the jacket area is used to monitor the temperature of the heat - exchange medium (such as steam or cooling water) in the jacket. Through the data feedback from these two groups of temperature sensors, the control system can precisely adjust the flow rate of the heat - exchange medium in the jacket, thereby strictly controlling the reaction temperature inside the reaction kettle. For example, during an exothermic reaction, when the internal temperature sensor detects that the temperature is approaching the upper limit of the reaction, the system automatically increases the flow rate of the cooling water to promptly remove the excess heat and prevent the reaction from getting out of control.
The pressure sensor is equally crucial. It monitors the pressure changes inside the reaction kettle in real - time. Since chemical reactions are often accompanied by the generation or consumption of gases, the pressure fluctuations directly reflect the progress and state of the reaction. Once the pressure exceeds the safe range, the pressure sensor immediately sends a signal to the control system, and the control system quickly takes corresponding measures, such as adjusting the feeding speed of the reaction materials or opening the pressure - relief device, to ensure the safe operation of the reaction kettle.
In addition, a level sensor is installed on the side of the reaction kettle to monitor the liquid - level height of the materials in the reaction kettle in real - time. This helps operators accurately control the amount of reaction materials added, avoiding material overflow due to excessive liquid - level or affecting the normal progress of the reaction due to too low a liquid - level. Through the monitoring data of the level sensor, combined with the data of other sensors, it is possible to accurately calculate the volume and mass of the materials in the reaction kettle, providing strong support for the optimization of the reaction process.
Through the coordinated operation of these industrial sensors, the operational safety of the enterprise's reaction kettles has been significantly improved, the stability of product quality has also been remarkably enhanced. The defective product rate has decreased from the original 5% to 2%, and at the same time, the production efficiency has increased by approximately 15%.
