CONTROL METHOD FOR WET FLUE GAS DESULFURISATION DEVICE, CONTROL DEVICE FOR WET FLUE GAS DESULFURISATION DEVICE, REMOTE MONITORING SYSTEM COMPRISING SAID CONTROL DEVICE FOR WET FLUE GAS DESULFURISATION DEVICE, INFORMATION PROCESSING DEVICE, AND INFORMATION PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/210827
Kind Code:
A1
Abstract:
A wet flue gas desulfurisation device comprises an absorption column, a circulating pump and an absorbing agent slurry supply unit. In this control method for said device, a learning model is constructed, by machine learning, for the relationship between: explanatory variables which include the absorbing agent concentration in an absorption liquid, the circulation flow rate of the absorption liquid and at least one parameter that correlates with the output of a generator; and a target variable which is a future concentration of sulfur dioxide at the outlet of the absorption column. For each generator output, a predicted value of the concentration of sulfur dioxide from the learning model is calculated, and a table indicating an introduced amount of the absorbing agent and a circulation flow rate of the absorption liquid that would be required for the predicted value to be less than or equal to a reference value is created. On the basis of said table, control target values are determined for the introduced amount of the absorbing agent and the circulation flow rate of the absorption liquid, which correspond to the state of the generator.
