Tubular Electrolyzer By Swirl Electrolysis Technology

Tubular electrolyzer by Swirl electrolysis technology
Cylindrical cells/Tubular electrolyzer by Swirl electrolysis technology adopts an anode mounted in the center of a cylindrical cathode, they are  featured for a high flow rate to enhance the rate of mass transfer, overcoming issues associated with depletion zones and enabling the production of high-purity metals even in the presence of impurities.
Traditional electro winning cells design with the planar electrode, current efficiencies plummet once the concentration of the electro won metal in solution decreases. Due to inadequate mixing, depletions forms around the cathode and at low concentrations, hydrogen evolution occurs and other unwanted materials are electrodeposited and the morphology of electrodeposited metal changes. This compromises both the efficiency and selectivity of the electro winning process.

Swirl electrolysis technology can overcome the above shortcomings. In a tubular electrolytic cell, there is a DSA anode rod inside, which rotates at high speed to drive the solution to rotate and improve electrolysis efficiency.

The core component of this technology is the tubular electrolyzer by swirl electrolysis:
