Introduction to swirl electrolysis technology

At present, the application areas of this technology include: copper, zinc, nickel, cobalt, lead, gold, silver, precious metals and wastewater treatment, and it has dozens of users all over the world. All electrolysis technologies are based on the basic theories of electrochemistry, and swirl electrolysis technology is no exception. The traditional electrolysis technology is to place the cathode and anode in a slow-flowing or stagnant tank. Under the action of an electric field, the anions move towards the anode and the cations move towards the cathode. By controlling certain technical conditions, the metal cations to be obtained are in the cathode. The electron deposition is obtained, and the electrolytic product is obtained.

Cyclone electrolysis technology is based on the difference in theoretical precipitation potential (E¢) of each metal ion, that is, as long as the metal to be extracted has a large potential difference with other metal ions in the solution system, the metal with a positive potential is likely to be preferred at the cathode. The key to precipitation is to eliminate the adverse effects of concentration polarization and other adverse effects on electrolysis through high-speed liquid flow.

The outstanding advantages of swirl electrolysis technology include:

(1) Portable or modular assembly, small footprint;

(2) Wide range of applications, the same device can treat multiple metals; in sewage treatment and metal recovery, etc.

(3) The solution is closed circuit, no harmful gas is discharged;

(4) Electrodeposit metal selectively;

(5) Higher current density and current efficiency;

(6) High-efficiency and high-purity electrolytic extraction is carried out on low-concentration solutions, and the metal recovery rate can reach the ppm level. Generally speaking, copper can be degraded to below 3g/L, and the cathode copper can reach 99.99%

Introduction of cyclone electrolysis device

1. The cathode cylinder is made of φ219*3*1550mm stainless steel (316L) or pure titanium (TA1)

2. Use 0.3-0.5mm TA2 titanium elastic plate for the starting electrode plate, processed into a φ219mm cylinder, and put it into the cathode cylinder.

3. The anode tube uses φ57*3*1500mm, φ57*3*1500mm or φ57*3*1500mm, and the conductive part is used

Use titanium-copper composite rods.


4. The anode tube is installed with the upper and lower positioning rods to position the anode tube in the middle of the cathode copper to ensure that the electrode spacing is equal, and the coating is titanium coated with iridium

5. The electrolyte is pumped into the cathode cylinder from bottom to top through the infusion pump at high speed to carry out eddy current electroplating of metal.

6. The current density of the commonly used cyclone electrolysis cathode is 500-600A/m2, and the anode current density is between 1400-1700.

7. The upper and lower plastic covers of this device are made of ABS plastic, and the upper cover has an exhaust port.

8. The conductive part is in the lower part. This device is based on groups. Generally, one group is 10-24 pieces, 10-24 pieces are connected in series, and groups are connected in parallel. The voltage of a single tank is about 2.5v.
