Description

Technical field: [0001] The invention belongs to the technical field of electrochemistry and relates to a distributed titanium alloy pipeline electrolysis antifouling device. Background technique: [0002] Titanium alloy has the advantages of light weight and resistance to seawater corrosion and erosion, and can be widely used in the manufacture of various seawater cooling systems and heat exchange systems or other key components, so as to reduce pipe diameter, increase flow rate, reduce weight and reduce corrosion effect. However, when titanium alloys are used in seawater, the adhesion of marine organisms is extremely serious. Direct electrolysis of seawater to produce strong oxidative antifouling agents such as sodium hypochlorite and chlorine gas to prevent marine biofouling is not only safer and more economical than the traditional addition of chlorine gas, but also the device is relatively easier. At present, the widely used electrolytic antifouling device is to first...

Problems solved by technology

Japanese Patent Laid-Open Gazette (A) 61-120687 provides a method for preventing marine organisms from adhering to seawater pipelines. The hydrophobic cylinder electrode is used to directly electrolyze seawater for antifouling, and the hydrophobic cylinder bushing is used for insulation. The cathode material is made of metal pipe wall or Hydrophobic cylindrical cathode, but these technologies and equipment are based on the traditional system of preparing antifouling agent at the water inlet and injecting it into the pipeline, and need to introduce the electrode assembly in the electrolytic antifouling system. There are many problems that need to be improved. technical problem
