AI Technical Summary

Technical Problem

In traditional baijiu distillation systems, uneven steam flow rate leads to uneven heat exchange in local areas, unstable alcohol concentration in the condensate, high energy consumption, and fixed control methods for fans and flow guiding devices that cannot adapt to changes in steam inertia or temperature difference, resulting in low energy efficiency.

Method used

The steam distribution module detects the flow rate and adjusts the fan impeller angle; the condensation state determination module uses a gradient boosting decision tree to correct the guide vane angle; the dynamic predictive control module uses a non-dominated sorting genetic algorithm to adjust the fan speed and guide vane angle; the energy efficiency balance module selects the optimal operating combination; and the safety linkage module monitors fan vibration and coil pressure to form a linkage control of the condensation system.

Benefits of technology

It achieves balanced steam flow rate, dynamic balance of condensation efficiency, and coordinated optimization of the fan and flow guiding device, thereby reducing energy consumption and improving the stability and energy efficiency of the condensation system.
