According to statistics, in the field of modern chemical industry, about 90% of chemical production processes use catalysts, and the purpose is to accelerate reaction rate and improve production efficiency. Therefore, the production and research and development work of the catalyst occupy an extremely important position in the field of modern chemical engineering. As a synthetic functional material with specific composition and structure, a plurality of technological processes of production and research and development of most catalysts need to use roasting equipment, for example, a catalyst carrier needs to be in the roasting equipment to complete the conversion of chemical components under the conditions of certain temperature rise and drop rate, gas flow and pressure; in addition, most active components of the catalyst have specific compositions and structures, and the forming process of the catalyst not only needs roasting equipment to accurately control the temperature rise and fall rate and the process temperature, but also needs to accurately regulate and control working state index parameters such as flow, pressure and the like of introduced gas. Therefore, the control system and method for the index parameters of the working state of the roasting equipment have important influence on the development and production process of the catalyst, and are important means for ensuring the quality reliability and batch consistency of the catalyst.
Although the automatic control of the temperature and the gas introduced into the catalyst calcination equipment at the present stage is mostly performed by adopting an artificial intelligent instrument with an AI-type PID regulating function, zero overshoot and zero undershoot can be basically realized, but one instrument can only control one parameter point, one set of catalyst calcination equipment needs several or even dozens of instruments to control, the operation is very complicated, and omission or misoperation is easily caused. In addition, the instruments need to be attended by people on site, manually collect and record process parameters, the workload is high, the efficiency is low, and error recording or omission recording is easy to occur. Because the catalyst roasting process takes longer time, and some of the catalyst needs tens of hours, the catalyst is attended by manpower on site, the labor cost is high, and the labor efficiency is low.
