Latest Patents

One of Pfalzgraff's latest patents is an "Electrode cap with integral tank cover for acid mist collection." This invention is designed for use in tank confined electrolysis processes, such as electrowinning or electrorefining, which utilize a circulated electroplating solution containing sulfuric acid. The multi-element cover system is strategically applied below the electrode conductor connections and above the surface of the electrolyte bath. The cover is evacuated in the interstices below it and above the bath at a rate that exceeds the stoichiometric ratio, effectively preventing acid aerosol from escaping. The evacuation rate is carefully controlled to maintain humidity under the cover and over the surface of the bath, thus preventing the formation of crystals from aerosol droplets that become supersaturated. A preferred embodiment of this invention includes a circular weir combined with gas discharge over the weir to a downcomer, ensuring sufficient air entrainment for effective evacuation.
