The galvanic anode consists of three groups of protectors. The first group of protectors is placed vertically on the central rack at the height of the aqueous phase, the second group is placed on the bottom of the RVS in concentric rings connected in series, and the third group is vertically on the side wall at the height of the aqueous phase, with the protectors of the third group connected to the outer ring of the anode located on the bottom. Each group is connected by a wire to the TVS housing in the junction box.
1 – Galvanic anode. 2 – Drainage wire.
3 – Junction box. 4 – Resistors.
5 – The working electrode. 6 – Potential measurement unit.
The galvanic anode is isolated from the surface of the TVS by gaskets (for example, polyethylene rings worn on the protector) and closed to the housing of the TVS through wire resistors, the resistance of which is calculated for each tank in order to limit the maximum current of the protector.
The effectiveness of the tread protection is determined by the magnitude of the cathodic polarization (displacement of the reservoir potential), measured relative to the working electrodes and (or) using a potential measuring unit mounted in the lower part of the side wall of the TVS.
The proposed technology provides a degree of protection of the inner surface of the RVS from corrosion in the aqueous phase of at least 90%, regardless of the nature of the liquid inside the TVS.
