Rectifying tower control method, device and equipment and computer readable storage medium

The embodiment of the invention provides a rectifying tower control method, device and equipment and a computer readable storage medium. The method comprises the following steps: acquiring the tower kettle operation temperature of a rectifying tower, the cooling temperature of tower kettle discharge after passing through a primary heat exchanger and the discharge flow of the rectifying tower; according to the tower kettle operation temperature, the cooling temperature and the discharging flow of the rectifying tower, the heating heat capable of being provided by the first-stage heat exchanger is calculated; the feeding flow of the rectifying tower and the initial feeding temperature of the rectifying tower are obtained; according to the heating heat, the feed flow and the initial temperature of the feed of the rectifying tower, the heating temperature of the feed after passing through the first-stage heat exchanger is calculated; according to the heating temperature, the heat exchange medium flow of the secon
