浅谈铝电解槽阳极保温及防氧化技术

Discussion on Anode Insulation and Anti-oxidation Technology of Aluminum Electrolysis Cell

设计一种电解槽上部结构,将传统电解槽上部结构单腔体-集气腔体调整为双腔体,即在原来的单一集气腔的下方增设保温腔。保温腔和集气腔间由保温盖板进行隔离,实现对阳极组进行保温和防止阳极氧化目的。借助机电一体化技术,对保温腔的工作状态进行时时监测,对保温盖板覆盖是否严密,保温腔的压力和温度进行检测。保温腔压力过高或温度过高时,自动进行泄压或降温处理。通过电解槽上部结构的调整、保温盖板和机电一体化技术的应用,可完全替代传统电解槽使用的覆盖料,必将大幅度降低电解生产成本和有效降低工人的劳动强度。

A superstructure of pot is designed.The single chamber-gas collecting chamber of the superstructure of traditional pot is adjusted to double chamber,that is to say,an thermal thermal insulating chamber is added below the original single gas collecting chamber.The insulating cover plate is used to isolate the thermal thermal insulating chamber and the gas collecting chamber,so as to realize the purpose of thermal insulating the anode group and preventing the anodic oxidation.With the help of Mechatronics technology,the working state of the thermal insulating chamber is monitored from time to time,and the tightness of the insulating cover,the pressure and temperature of the thermal insulating chamber are tested.When the pressure of the thermal insulating chamber is too high or the temperature is too high,the pressure relief or cooling treatment will be carried out automatically.Through the adjustment of the upper structure of the pot,the application of insulating cover plate and electromechanical integration technology,it can completely replace the covering material used in the traditional pot,and will greatly reduce the production cost of electrolysis and the labor intensity of workers.At the same time,it can effectively reduce the adverse effects of production on the surrounding environment.
