Automatic control system and control method for bromine distillation tower

The embodiment of the invention provides an automatic control system and method for a bromine distillation tower. The system comprises an image acquisition camera mounted at a window position of a bromine distillation tower, a temperature sensor mounted at the top of the bromine distillation tower, a chlorine valve mounted on a chlorine pipeline of the bromine distillation tower, a steam valve mounted on a steam pipeline of the bromine distillation tower, a pressure sensor mounted on an outlet pipeline of the steam valve, an industrial personal computer and a controller. The image acquisition camera is connected with the industrial personal computer. The industrial personal computer is connected with the controller. The controller is connected with the temperature sensor, the chlorine valve, the steam valve and the pressure sensor. By applying the scheme provided by the embodiment of the invention, the automation degree of bromine extraction can be improved, and the operation intensity of operators is reduced
