Ammonia desulphurization absorbent product S oxidation system and optimal regulation and control method

The invention discloses an ammonia desulphurization absorbent product S oxidation system and an optimal regulation and control method, and belongs to the technical field of air pollution control. Model parameters in an ammonia desulphurization system are determined at first; the model parameters are input, an initial pH value, an oxidation air capacity Q and initial concentrations (shown in the description) of S and S are set, and the oxidation ratio r(IV)V/MSO2 of S in a slurry pond is calculated by use of an oxidation ratio model of S ; the oxidation ratio r(IV)V/MSO2 of S is substituted into |r(IV)V/MSO2-CS /Cs| and CS are re-calculated till |r(IV)V/MSO2-CS /Cs| and CS in the model are adjusted to ensure that the oxidation ratio of S can meet the project demand. The oxidation ratio model can provide theoretical reference for the design and the operation of the ammonia desulphurization absorbent product S oxidation system, and further, the stability and the economical efficiency of the ammonia desulphurization technology are improved.
