Abstract
The present disclosure provides an automatic control system for emission indexes of a desulfurization device of a thermal power unit, which comprises a first controller, a second controller and a flow controller. At the same time, the present disclosure provides an automatic control method for emission indexes of a desulfurization device of a thermal power unit. The present disclosure runs through the production and operation data of waste gas desulfurization treatment facilities, and establishes a pH optimization set value prediction model according to the data, and can realize automatic regulation and control of pH value by optimizing and controlling the pH optimization set value and the slurry flow optimization set value every moment through the dynamic model, thus solving the problem that the pH value control process is large in lag and slow in dynamics, and improving the pH value control quality.
