ABSTRACT:
An electrolyzer for obtaining chemical products, comprising a cell having its inner surface made from a dielectric material, and filled with a circulating electrolyte; the cell accommodates current leads which are nonsoluble, the space between the current leads and the walls of the cell being filled with pieces of a conducting material, said pieces serving as a bulk electrode, and as these pieces react with the electrolyte, a coat of film is formed thereon, which promotes the bipolar action of said pieces when the current leads are energized; in addition, the cell is provided with a means for discharging slime and the products of electrolysis.
A method of conducting electrolysis in the electrolyzer, which consists in charging the space between the current leads in layers with pieces of a conducting material, which pieces, when reacting with the circulating electrolyte, receive a coat of film of high resistance, said film promoting the bipolar action of the pieces and preventing current leakage through the metallic contact between said pieces; the current leads in the electrolyzer are then energized, creating an electric field providing for a potential difference across the oppositely charged portions of adjacent pieces, said potential difference being sufficient for obtaining the desired product; the electrolyte is made to circulate through the use of the lifting force of the gases evolving during the electrolysis, said gases saturating the electrolyte impairing its conductivity and impeding thereby current leakage through the electrolyte.
