A fully digital electrolyzer and its integrated intelligent control system

Abstract

The invention discloses a fully digital electrolytic tank and an integrated intelligent control system. The control system comprises a fully digital electrolytic tank (1), an integrated intelligent control unit (2), a movable type electrolytic plant integrated unit (3), and an enterprise grade big data unit (4). Through multiple distribution type sampling systems, electrolytic tank data is collected and multisource information is processed to establish a digitalized electrolytic tank; decision strategy and control commands related with precise effect control, tank stability and overheat control, zone concentration and anode state are formed automatically; the electrolytic tank is controlled, at the same time, mass data is stored in a data center in a text form, and thus people can see theinformation and execute the commands through a mobile terminal in the field. The system is applied to a large aluminum electrolysis system, can save the energy and improve the efficiency, creates an ultralow anode effect, and only needs very few people.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolysis, and in particular relates to an all-digital electrolytic cell and an integrated intelligent control system thereof. Background technique [0002] In recent years, various energy-saving and consumption-reducing technologies around aluminum electrolysis have emerged continuously, and have achieved excellent indicators under the cooperation of relatively ideal technological conditions. There has been a rebound, especially for enterprises that purchase alumina production in Henan and Shanxi. Due to the continuous increase in lithium and potassium content, the electrolyte system has become complicated, the electrolysis temperature has dropped, the production of electrolytes with low molecular ratios has become viscous, and the hammer head is long. , easy to block materials, frequent local effects, difficult to extinguish the effect, large fluctuations in the stability of the electrolytic...
