An integrated high-efficiency antifouling electrode and electrolytic antifouling device for titanium alloy seawater pipelines

Abstract

The invention provides an integrated high-efficiency antifouling electrode and an electrolysis antifouling device used for a titanium alloy seawater pipeline, and belongs to the field of halobios fouling control for seawater pipelines. The integrated high-efficiency antifouling electrode is designed with an independent cathode body, so that the key problem that hydrogen embrittlement can be easily generated on the titanium alloy seawater pipeline when the titanium alloy seawater pipeline is used as a cathode is solved; the cross section of the cathode body is a closed ring, and defines the outer side of an anode body, and thus, current produced by the anode body is enabled to be basically absorbed by the cathode body, and the problem that stray current corrosion is generated by electrolysis antifouling is avoided; the electrode is designed with an anode conductor, so that space required by installation of the electrode is obviously reduced, and meanwhile, two ways of anode electrolysis current can be controlled independently, and therefore, an antifouling compound is prepared with accurate concentration, and a good antifouling effect is ensured. The electrode is employed by the electrolysis antifouling device, and an alarm device for the service life of the electrode is designed, so that the safety problem possibly caused by anode overelectrolysis is solved, the titanium alloy seawater pipeline is enabled to gain a good halobios fouling control effect, and all related systems are enabled to be stable and safe in operation.

Description

technical field [0001] The invention belongs to the field of marine biofouling prevention and control for seawater piping systems, and relates to an integrated high-efficiency antifouling electrode and an electrolytic antifouling device for titanium alloy seawater pipelines. Background technique [0002] Titanium alloy has excellent properties such as low density, high strength, and seawater corrosion resistance. It is more and more widely used in seawater piping systems in engineering fields such as ships, offshore platforms, ports, and natural gas liquefaction. The application of titanium alloy can reduce the diameter of the pipeline and increase the flow rate of seawater, which has a significant effect on reducing the weight of the pipeline and reducing corrosion. However, titanium alloys have good biocompatibility and are prone to serious marine biofouling problems in practical applications. Fouling can cause blockage of pipelines, decrease of heat transfer efficiency o...
