摘要： A multi-element cover system for controlling acid mist in metal electrowinning or electrorefining cells is made of an electrolyte resistant material and is applied above the surface of the electrolyte and below the electrical connections of the electrodes in order to provide a continuous and substantially airtight seal above the electrolyte. The cover system comprises a plurality of flexible longitudinally concave caps arranged between the cathode and the anode that help to shift the acid mist towards the sides of the cell using the same energy that disengages it from the electrolyte; lids between the electrodes and the wall of the corresponding end of the cell; and lateral enclosures located at both sides of the cell in the space between the electrodes and the lateral walls of the cell, the lateral enclosures having at least a top side, end walls at each end and an inner side projecting towards the electrolyte, thus forming a chamber inside the lateral enclosure, with the lower side of the enclosure or the electrolyte itself acting as the bottom boundary of the chamber, the chamber being connected to external acid mist suction means and its inner side provided with bores above the electrolyte level so as to in this fashion, in collaboration with the flexible caps, uniformly suck and remove the acid mist confined under the caps throughout the entire cell with a gentle suction and without the risk of crystal formation due to oversaturation of the droplets contained in the mist.

摘要： Disclosed herein are a method and apparatus for preparing metal nanoparticles using alternating current (AC) electrolysis, in which the yield of metal nanoparticles obtained can be greatly improved by maintaining the concentrations of a reducing agent and a dispersing agent at constant levels in proportion to the intensity of an electric current during the production of the metal nanoparticles. The method for preparing metal nanoparticles comprises the steps of: dissolving an electrolyte and a dispersing agent in pure water in a reactor to prepare an electrolytic solution; placing first and second electrodes apart from each other in the electrolytic solution in the reactor, the electrodes being made of the same material as metal nanoparticles to be obtained; applying alternating current at the first and second electrodes to ionize the metal of the first and second electrodes in the electrolytic solution; and introducing into the electrolytic solution a reducing agent so as to maintain the reducing agent at a constant level according to the concentration of metal ions produced, thereby reducing the metal ions to obtain the metal nanoparticles.

摘要： Disclosed is an aluminum electrolytic cell having profiled cathode carbon blocks structures, comprising a cell case, a refractory material installed on the bottom, an anodes and a cathode. The cathode carbon blocks include a profiled structure having projections on the top surface of the carbon blocks, that is, a plurality of projections are formed on a surface of the cathode carbon blocks. The aluminum electrolytic cell having the cathode structure according to the present invention can reduce the velocity of the flow and the fluctuation of the level of the cathodal molten aluminum within the electrolytic cell, so as to increase the stability of the surface of molten aluminum, reduce the molten lose of the aluminum, increase the current efficiency, reduce the inter electrode distance, and reduce the energy consumption of the production of aluminum by electrolysis. With the above configuration, compounds or precipitates of viscous cryolite molten alumina can be formed on the lower portion between walls protruding on the upper surface of the cathode, which can prohibit the molten aluminum from flowing into the cell bottom through the cracks and apertures on cathodes, so that the life of the electrolytic cell can be extended.

摘要： Alkali metals and sulfur may be recovered from alkali polysulfides in an electrolytic process that utilizes an electrolytic cell having an alkali ion conductive membrane. An anolyte solution includes an alkali polysulfide and a solvent that dissolves elemental sulfur. A catholyte solution includes alkali metal ions and a catholyte solvent. Applying an electric current oxidizes sulfur in the anolyte compartment, causes alkali metal ions to pass through the alkali ion conductive membrane to the catholyte compartment, and reduces the alkali metal ions in the catholyte compartment. Sulfur is recovered by removing and cooling a portion of the anolyte solution to precipitate solid phase sulfur. Operating the cell at low temperature causes elemental alkali metal to plate onto the cathode. The cathode may be removed to recover the alkali metal in batch mode or configured as a flexible band to continuously loop outside the catholyte compartment to remove the alkali metal.
