Abstract

The invention discloses a limestone slurry preparation system and a control method. The limestone slurry preparation system comprises a limestone slurry box, a water feeding pump, a limestone powder bin, a feeder and a controller, the controller is used for starting the water feeding pump and the feeder when detecting a system starting instruction, the system is made to execute a preset operation mode, the current set output, the current set opening degree and the current set feeding time which enable the slurry density to be qualified and stable are determined according to the difference value between the current density and the expected density of the slurry in the limestone slurry box, the maximum output of the feeding machine is finally guaranteed through continuous iteration, and it is guaranteed that slurry preparation is completed within the shortest time; the power consumption of the feeder is reduced, the density stability of the slurry in the slurry preparation process is improved, and the quality of the slurry is improved.

Description

technical field [0001] The present application relates to the technical field of desulfurization process control, and more specifically, to a limestone slurry preparation system and control method. Background technique [0002] With the rapid development of the thermal power industry and the gradual improvement and standardization of my country's environmental protection system, the investment and stable operation of flue gas desulfurization process equipment has become a matter of great concern to thermal power companies. In the wet desulfurization process of thermal power plants, limestone slurry is the main raw material for the chemical reaction of flue gas desulfurization. Factors such as the concentration of limestone slurry and the pulping rate affect the efficiency and safe operation of the desulfurization process. [0003] At present, the desulfurization limestone slurry preparation system of thermal power plants adopts the method of mixing limestone powder and water...
