Improved Design of Sensitive Diathermancy and Application in High Accuracy Chemical Unite Operation

Abstract

The high accuracy of heat inspect system was very important for the use of accuracy control in the chemical industry. The difficult of high accuracy of heat inspect system was how to get the heat information with high accuracy and control the system at real time. In traditional method, the linear system was used to control the feedback of the heat, with the data sampled discrete, the model-based heat inspect of chemical industry was easily influenced by modeling errors and disturbances of complex chemical environment, which cause underreporting or false alarms, the result was not good. So a high accuracy application of sensitive diathermancy design method was proposed and applied in high accuracy chemical unite operation and chemical industry, a heat inspect method of principal component cluster analysis for the chemical industry, the accurate diathermancy heat inspect data was sampled with many sensitive diathermancy in different location, the corresponding heat inspect signal through effective heat inspect method was analyzed to deter the corresponding chemical diathermancy was faulty, with the data fusion method, the accurate data was output to control the system. Simulation results show that with sensitive diathermancy used in chemical unit operation, the heat data is outputted with high accuracy, and it has good application value in chemical industry.
