Example Embodiment

[0032] The present invention will be further elaborated and illustrated below in conjunction with the drawings and specific embodiments. The technical features of the various embodiments of the present invention can be combined accordingly without conflict with each other.

[0033] Such as figure 1 Shown is the overall equipment for the bromine distillation process provided in a preferred embodiment of the present invention. The main body of the equipment is a distillation tower, and the inside of the distillation tower is used for the distillation and purification reaction of chlorine and steam. Two transparent windows are opened on the side wall of the distillation tower opposite to each other. One window is used to install the industrial visual recognition system, and the other window is installed with a light source to fill the reactants inside the tower. The image obtained by the industrial visual recognition system is clearer. The industrial visual recognition system can ...

Abstract

The invention discloses a chlorination control method based on visual recognition in a bromine distillation process, and an apparatus, and belongs to the field of bromine extraction equipment. According to the method, according to the optimal bromine quality in a bromine distillation process, the optimal color depth interval of the reactant in a corresponding distillation tower and the opening degree of the control valve on a chlorine gas inlet pipe are determined in advance; during the operating of the bromine distillation process, the color depth of the reactant in the distillation tower isreal-timely monitored through a visual recognition method, and whether the color depth of the current reactant is within an optimal color depth interval is determined; and if the color depth of the current reactant deviates from the optimal color depth interval, the opening degree of the control valve is adjusted within the control valve opening degree, such that the color of the current reactantis restored to the optimal color depth interval. According to the present invention, with the method, the adding amount of chlorine gas can be controlled through visual recognition to eliminate the influence of human factors so as to ensure the yield and the quality of bromine.

Description

technical field [0001] The invention belongs to the field of bromine extraction equipment, and in particular relates to a visual recognition-based chlorine addition control method and device in a bromine distillation process. Background technique [0002] Distillation is the final step in the bromine production process, where bromine is purified by reacting with chlorine gas and steam. The effect of distillation control directly affects the yield and quality of bromine. The traditional adjustment mode is to manually observe the color of the glass tubes at the top and bottom of the distillation tower, and adjust the amount of chlorine added according to the color. Uncertain factors of human control will lead to excessive or insufficient chlorine gas. Excessive addition of chlorine gas will affect the quality of bromine, while insufficient addition of chlorine gas will affect the extraction rate of bromine. [0003] Therefore, how to accurately and automatically control the ...
