The application relates to an
ethoxylation reaction stage temperature optimization control method, device, equipment and readable storage medium. The method comprises the following steps: obtaining an
ethylene oxide feed flow cumulative amount as a reaction progress judgment benchmark; dividing multiple reaction stages according to the cumulative amount, and presetting a control parameter group for each stage; calculating the cumulative amount in real time, automatically switching the stage when a preset threshold is reached and a
precondition is met, and the parameter group of each stage is executed only once; performing
cascade control of the kettle bottom temperature and the feed flow according to a feed flow benchmark value to actively adjust the reaction heat release; and automatically switching a heat conduction oil control strategy without disturbance according to a heat conduction oil
control mode. The method realizes self-
adaptive control of
ethoxylation reaction in stages, actively controls temperature from the source, overcomes the
hysteresis of traditional passive heat removal, and improves
temperature control precision and production safety. Moreover, the method is also suitable for strong exothermic and staged
batch reaction processes of propoxylation or polyesterification.
