Abstract

Cella di elettrolisi cloro-soda a diaframma comprendente catodi e anodi intercalati in cui i catodi sono provvisti di superfici dotate di aperture e rivestiti con diaframmi porosi e gli anodi sono del tipo espandibile e provvisti di superfici mobili dotate di aperture per consentire l'evacuazione del cloro gassoso prodotto. Tale cella é caratterizzata dal fatto che gli anodi sono espansi e ulteriormente pressati contro i diaframmi mediante l'uso di almeno un dilatatore addizionale inserito in ciascuno di detti anodi.Detti anodi sono preferibilmente equipaggiati con reti espanse sottili fissate a ciascuna delle superfici mobili e con dispositivi idrodinamici atti ad aumentare la circolazione interna.
