▎ 摘　　要

NOVELTY - The device has a metal pipe (1) for cooling seawater unit (5) i.e. white copper pipe, a graphene electrode (2) and an external power supply (3) i.e. direct current power supply. The metal pipe, the graphene electrode and the external power supply are electrically connected together, where the metal pipe is a negative electrode and the graphene electrode is a positive electrode. An inner surface of the white copper pipe is provided with a titanium plating layer (4), where thickness of the titanium plating layer is measured about 5 to 15 micro m and 12 to 15 micro m. USE - Device for anti-corrosion sterilizing for a sea water cooling pipeline of a large power frequency converter. ADVANTAGE - The device utilizes sea water as cooling medium, utilizes a plating titanium white copper pipe as heat-conducting medium for chemical sterilizing without considering cost, which simplifies device investment, reduces floor space, and has good practical and economic value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for anti-corrosion sterilizing for a sea water cooling pipeline of a large power frequency converter. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a device for anti-corrosion sterilizing for a sea water cooling pipeline of a large power frequency converter.
