ANODE BED Russian patent published in 2019 - IPC C23F13/02 C23F13/16 

FIELD: chemistry.

SUBSTANCE: invention relates to electrochemical protection and can be used for anode bed of installations of electrochemical protection of metal and reinforced concrete structures from corrosion, which contact with high-resistance soil. Anode bed electrode comprises electrode and external connecting element, at that, electrode body is made solid from electrically conductive polymer material in form of pipe, wherein in electrode body there is a filling hole, lower end of electrode body is plugged and activator is located in electrode body cavity, wherein the external connecting element containing the cable connected to the electrode body is fixed on the upper end of the electrode body by means of the connecting unit and the electrode body made in the form of a pipe is made with multiple perforated holes communicated with the filling hole as fluid medium. Also disclosed is a method of making such anode bed electrode and method of cathodic protection using it.

EFFECT: invention increases reliability and durability of the anode bed electrode, as well as increases efficiency of its operation in sandy soils or high-resistivity soils.
