A water spray amount control method and system for a drum

Abstract

This invention relates to the field of sand spraying technology, and more particularly to a method and system for controlling the spray volume of a drum. The method includes the following steps: calculating the theoretical spray volume for each control cycle based on the inlet flow rate, inlet temperature, and target temperature; adjusting the final spray volume of the previous control cycle according to the deviation between the actual cooling gain and the desired cooling gain of the drum in the previous control cycle to obtain the economic spray volume for that control cycle; acquiring the theoretical and economic spray volumes of the control cycle in parallel, and weighting and fusing the theoretical and economic spray volumes according to a reliability weight to obtain the final spray volume for that control cycle; controlling the spray rate of the drum according to the final spray volume to achieve spray volume control of the drum, which can effectively improve the accuracy of the drum spray volume calculation, thereby effectively improving the efficiency of spray volume control.
