Description
Technical field
The utility model is related to a kind of electrolysis unit applied in seawaterline, for the anti-of seawaterline and its annex
It is rotten.
Background technology
Ship seawaterline is small due to pipe diameter, and the annex such as elbow, threeway, valve is more, and straight length is short, seawater velocity
Height, the reason such as turbulence level is big, not only corrosion failure is serious, and corrosion protection is extremely difficult.Additional power source protection does not have so far
Apply with succeeding, the protection of sacrificial anode is widely used.But when using anode loss protection, due to
Seawaterline pipe diameter is mostly smaller, therefore current shielding is serious, and anode spacing is very limited, in ship seawater pipe
Carry out whole process protection in road, it is difficult quite big, it is necessary to considerable anode, and sacrificial anode is on naval vessel seawaterline
Mounting condition and can useful load it is extremely limited, it is impossible to the sacrificial anode for loading sufficient amount carries out whole cathodic protection, therefore only
Can be for the seriously corroded pipeline section implementation focus cathodic protection scheme such as bend pipe, threeway, pump, valve import and export.Due to seawaterline
Exposed to flowing and in the briny environment containing sand, protecting current density is higher needed for cathodic protection, therefore sacrificial anode is consumed
It hurry up, due to the limited volume of seawaterline, it is also contemplated that the influence to fluid resistance, anode can not be made larger, therefore anode
Life-span be very restricted, it is therefore necessary within a short period of time according to design requirement regularly replace anode.Seawaterline
Main Breakage Reasons are impingment corrosions, and impingment corrosion increases with the increase of seawater velocity.Every kind of seawaterline material has one
Individual critical flow velocity value, impingment corrosion destruction will be extremely serious when seawater velocity exceedes the value.Therefore, as seawater pipeline material,
All regulation has a permission design current velocity value.Under higher seawater velocity, merely using anode loss protection, still relatively it is difficult to resolve
Certainly corrode leakage problem.
The etching problem and sea marine organism pollution existed for copper and copper alloy seawaterline, it is single that technical measures are solved at present
Only cathode copper, iron anode realize the antifouling method of corrosion protection, but there is electrode material and consume too fast, and electrolytic anode material filming is prevented
The problems such as rotten anti-fouling effect is not enough and installing space is limited.
The content of the invention
The utility model aims to provide a kind of electrolysis unit applied in seawaterline, to solve the electrolysis that presently, there are
The problem of anode material film forming anticorrosion and antifouling is not sufficiently effective and installing space is limited.
The technical solution of the utility model is：A kind of electrolysis unit applied in seawaterline, it is characterised in that including
Electrolysis power, sea water tank and electrode assemblie, are provided with seawaterline interface and valve, in the sea water tank at the two ends of the sea water tank
Equipped with electrode assemblie；The electrode assemblie includes electrode bar, insulating supporting disk and flange, is provided with insulating supporting disk
Multiple anode fixing grooves being uniformly distributed along the circumference or hole, the two ends of many cylindrical electrode bars are separately fixed at two insulation branch
Hold round on disk in corresponding anode fixing groove or hole, in the outer face connecting interface flange of an insulating supporting disk；The electrode
The number of rod is even number, and the adjacent electrode bar is insulated from each other, is divided into two groups of identical quantity, is connected to the positive and negative of electrolysis power
Cathode and anode is used as on extremely.
Described electrolysis power is main from for providing the direct current Constant Electric Current of DC electrolysis electric current to described electrode assemblie
Source and the polar converter composition for periodically changing two arrays of electrodes rod polarity in sea water tank.
Described electrode bar uses iron copper composite anode.
The utility model has the advantages that：Using the electrolytic iron copper composite anode of this structure using simple to operate, dimension is installed
Shield is convenient, saves space-consuming, improves antiseptic effect.
