The invention provides a high tower nitro fertilizer safety production automatic control system which comprises at least two mixing tanks for producing nitro fertilizer. An equipment assembly required for safely producing the nitro fertilizer in each mixing tank comprises a temperature detector for detecting the temperature of the mixing tank, a heating valve which is arranged on the steam pipeline and is used for controlling the on and off of the steam pipeline, a water adding valve which is arranged on the cold water pipeline and is used for controlling the cold water pipeline, and a motor for controlling a stirrer; when the first-stage interlocking condition is met, the heating valve is controlled to turn off the corresponding steam pipeline so as to stop continuously supplying steam into the corresponding mixing tank; the first-stage interlocking condition is related to the temperature of the mixing tank; when the second-stage interlocking condition is met, the water adding valve is controlled to open the
