Description
Изобретение относнтс к электрометаллургии и прикладной электрохимии . Преимущественной областью его использовани вл етс электролиз расплавленных солей с горизонтально расположенными электродами. Наиболь ший интерес изобр.етение предст авл ет дл алюминиевой промышленности в св зи с крупными масштабами производства алюмини . Известен способ устранени анодн го эффекта при электрол 1зе расплавленных солей путем вибрации электро лита. В частности, вибраци электро лита происходит за счет вибрации анода с довольно высокой частотой 1-300 Гц i . Способ не находит промышленного применени , так как реализаци его на практике св зана с большими техническими трудност ми. Привести ано весом 100 т и более в состо ние колебаний относительно высокой часТ :ты можно только с помощью достаточно сложных и дорогих механических устройств. Вибраци самого анода сопровождаетс нарушением герметизации электролизера по периметру соприкосновени анода с электролигом . Кроме того, нарушаетс электрр изол ци в ступен х, злектроизолиру-, 1апщх анодную и катодную части ванны, нарушаемс механическа прочность узлов креплени :подвески: анода.Наконец , анодныйэффект имеет локальHt характер i. реализуетс только в газожидкостном слое на границе раздела анод-электролит, и поэтому эффективность технических решений вьапе, если они направлены непосредственно на колебание газожидкостного сло . Целью изобретени вл етс - повышение эффективности способа и упрощение его аппаратурного оформлени . Это достигаетс тем, что вибрацию электролиту сообщают путем создани в расположенной над ним в замкнутом объеме газовой фазе переменного . избыточного давлени 5-lcf н/м с частотой изменени . Замкнутым объемом могут служить, например, каналы, выполненные в теле анода, и система их св ди с пневматическим пульсатором. Повышение эффективности способа и упрощение его аппаратурного оформлени обеспечиваютс тем, что вибраци передаетс электролиту через Газовую фазу, котора , в свою очередь, воспринимаетThe invention relates to electrometallurgy and applied electrochemistry. The preferred area of use is the electrolysis of molten salts with horizontally placed electrodes. The greatest interest in the invention of aluminum is for the aluminum industry due to the large scale aluminum production. There is a known method for eliminating the anodic effect in an electrolyte of molten salts by electrolyte vibration. In particular, electrolyte vibration occurs due to vibration of the anode with a rather high frequency of 1-300 Hz i. The method does not find industrial application, since its implementation in practice is associated with great technical difficulties. To bring ano weighing 100 tons or more into a state of oscillations of a relatively high frequency: you can only do this with the help of quite complex and expensive mechanical devices. Vibration of the anode itself is accompanied by a violation of the cell sealing around the perimeter of the contact of the anode with the electrolyte. In addition, the electrical insulation in the steps is disturbed, the electrolysis is insulated, the anodic and cathodic parts of the bath, the mechanical strength of the attachment points: suspension: anode is broken. Finally, the anodic effect has a local character i. it is realized only in the gas-liquid layer at the anode-electrolyte interface, and therefore, the effectiveness of the technical solutions, if they are aimed directly at the oscillation of the gas-liquid layer. The aim of the invention is to increase the efficiency of the method and simplify its instrumentation. This is achieved by vibrating the electrolyte by generating a variable gas in the gas phase located above it in a confined space. overpressure 5-lcf n / m with frequency of change. Closed volume can be, for example, channels made in the body of the anode, and their system with pneumatic pulsator. Improving the efficiency of the method and simplifying its instrumentation is ensured by the fact that the vibration is transmitted to the electrolyte through the gas phase, which, in turn, perceives
