Coated titanium anode tubes for cyclone electrolysis

Cyclone electrolysis is an effective method to separate and purify metals. At present, the application fields of this technology include copper, zinc, nickel, cobalt, lead, gold, silver and precious metals.

Cyclone electrolysis technology is a new technology capable of selective electrolysis (electrowinning) of valuable metals. It is especially suitable for the metallurgical industry to separate and purify the selective electrolysis (electrowinning) of low concentration solutions and complex solutions, and to strip the heavy metal ions in wastewater.

All electrolysis technologies are based on the basic theory of electrochemistry, and cyclone 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 effect of the electric field, the anions move directionally to the anode and the cations move directionally to the cathode. By controlling certain technical conditions, the metal cations to be obtained are electrodeposited at the cathode to obtain electrolytic products.

Main device of cyclone electrolysis

Each cyclone electrolysis device uses stainless steel (titanium) as the cathode cylinder, and elastic titanium plate as the cathode starting plate, which is placed in the cylinder and closely attached to the inner wall. According to the concentration of metal ions in the solution, the cathode can finally control the precipitation of products. The cathode can precipitate metal pipes or metal powder, and the anode is titanium coated anode.

Main components of the device:

(1) Cathode component: the cathode of the electrolysis device is the main part of the electrolysis device. The pipes are made of 108/219mm diameter stainless steel pipes or titanium pipes.

(2) Anode assembly: it is the core part of the device, which is formed by titanium mesh/titanium tube with a diameter of 60/76mm and coated with platinum group precious metals.

(3) End (ABS/PVC): The end of the electrolysis device is molded and machined by ABS plastic. This part has the inlet and outlet of the solution and is connected with the corresponding inlet and outlet pipes. At the same time, the top end part is equipped with a gas outlet.

(4) End cap: each end is equipped with an end cap, which is connected by thread.

Working process of cyclone electrolysis device Working process of cyclone electrolysis device:

The solution containing metal ions enters the swirl tank from the bottom of the tank under the action of the infusion pump, flows at a high speed in the tank body, and metal deposits are precipitated from the cathode. As the coated titanium anode is used, gas is precipitated on the anode, and the gas is discharged at any time through the exhaust device on the top of the tank and concentrated for subsequent treatment. The cyclone cell works with several cells as a module, and a single cyclone cell is equivalent to a pair of cathode and anode of a traditional electrolytic cell. The cathode products are taken out from the top regularly (the powder is taken from the bottom), and the electrolysis is continued after the starting electrode is placed again.

Titanium anode for chlorine evolution is made of titanium plate, titanium mesh and titanium tube, coated with precious metal oxides such as ruthenium, which has a strong chlorine evolution potential and is widely used in sterilization and electrochemical synthesis industries.
