The invention relates to the technical field of
chemical engineering system optimization, and discloses a planning design
verification method for an electrolytic
manganese hydrogen production-chlor-alkali
chemical engineering coupling system. The method comprises the following steps: acquiring first real-time operation parameters such as
current density and
cell pressure of an electrolytic
manganese hydrogen production unit, and second real-time operation parameters such as alkali liquor concentration and
hydrogen purity of a chlor-alkali chemical unit; screening a matching operation section matched with the current
hydrogen production fluctuation characteristic from the historical
coupling operation data; analyzing the bath pressure change on the
time sequence of the matched operation section to determine a
coupling response action point, and calculating the coupling
delay amount from the starting point to the action point; then comparing the
current density before and after the coupling response action point with the change trend of the
hydrogen purity data sequence, and determining a parameter matching degree; determining a coupling
weight coefficient by combining the coupling
delay amount, the parameter matching degree and the fluctuation characteristic difference; and inputting the generated dynamic efficiency coefficient and the first real-time operation parameter into a
system verification controller, and outputting a system adjustment instruction, so that accurate planning
verification of the
coupling system can be realized.
