Intelligent regulating method for furnace pressure of glass melting furnace

The invention belongs to an intelligent control and regulating method in the glass production field and specifically relates to an intelligent regulating method for furnace pressure of a glass melting furnace. The method comprises the steps: combining with glass production experience, advanced control, a mathematical model, data acquisition and data processing functions, utilizing an intelligent controller to control a differential pressure transformer to acquire furnace pressure data in multiple commutation cycles, storing and processing the furnace pressure data through an intelligent control system, and further establishing the mathematic model; controlling and regulating the openness of a gate to change the furnace pressure according to the mathematic model and the openness, which is preset by a program inside the intelligent controller, of a flue regulating gate; meanwhile, acquiring the furnace pressure through the differential pressure transformer, comparing a furnace pressure measured value with a preset value, cyclically performing the regulation for many times, and performing level regulation and rolling optimization to enable the furnace pressure to be relatively stable. PID (Piping and Instruments Diagram) in the traditional non-commutation process is realized through the intelligent control system, thus no manual interference in the commutation process is realized and high-precision accurate control of the furnace pressure of a full-automatic melting furnace is realized.
