The invention relates to the technical field of desulfurization, in particular to a desulfurization
slurry control method and device based on a self-attention mechanism, and the method comprises the steps: collecting parameters of a desulfurization
system in real time, building a variable correlation thermodynamic map, and constructing a
hybrid prediction model for simulating
chemical reaction kinetic characteristics by using a delayed feedback mechanism; outputting a multi-target variable prediction result in the desulfurization efficiency, the SO2 concentration at an outlet and the pH value of the
slurry; generating a
slurry supply strategy based on the multi-target variable prediction result and a pre-constructed slurry supply strategy optimization model in combination with a preset
expert system rule; and dynamically optimizing a slurry supply strategy according to the operation state of the desulfurization
system. Therefore, the problems that in the prior art, due to the fact that univariate adjustment and empirical parameter setting are generally taken as the principal thing, the overall modeling capacity for the multivariate
coupling relation in the desulfurization process is lacked, control response
lag is likely to be caused, the adjustment precision is insufficient, robustness to external disturbance is weak, and emission stability and operation economical efficiency are difficult to consider at the same time are solved.
