Abstract

The present application belongs to the field of intelligent control of industrial kiln, and particularly relates to a pneumatic thermal zoning intelligent control system and method for industrial kiln. In view of the problems of poor temperature control accuracy, slow response and high energy consumption of the existing kiln, the system comprises a sensing unit, a decision unit and an execution unit. The sensing unit acquires real-time temperature dynamics by using a high-temperature-resistant sensor array; the decision unit generates a pneumatic adjustment instruction by solving a controller integrated with a PID architecture; the execution unit controls the flow by using a pneumatic adjustment mechanism, and generates ultra-low temperature cold flow by vortex conversion inside a pneumatic thermal generation device, which is injected into the thermal zoning by a jet nozzle array. The present application replaces the traditional indirect cooling method by directly injecting cold medium into hot spots, eliminates heat conduction lag, improves response speed and ensures minimal fluctuation of temperature control accuracy. At the same time, the vortex energy separation principle is used to reduce the operating power consumption and maintenance cost, and to realize intelligent targeted adjustment and zoning accurate control of the kiln thermal field.
