Description
One, technical field
The utility model relates to a kind of cathode protection device that the oil water separator inner wall anti-corrosive is used.
Two, background technology
The oil field oil water eliminator is the visual plant that natural gas, crude oil, aqueous mixtures in the underground crude oil of oil well output is separated into gas (top), crude oil (middle part), water (bottom accounts for half liquid level of eliminator).So, be necessary very much it is taked effective anti-corrosion measure in order to reduce evaporating, emitting, dripping or leaking of liquid or gas phenomenon and the security risk in running cost and the minimizing running application life that prolongs eliminator.But eliminator internal construction complexity, oil field oil recovery development late stage oil well average moisture content be about 85%, thus eliminator inner bottom part position over half in isolated sewage medium, etching problem is very serious.
Corrosion for eliminator inwall bottom mainly shows as electrochemical corrosion.The one, because oil product is stored, is failed moisture entrained between the refunding and all is deposited on the eliminator bottom by the moisture that the condensate water of gas phase steam is sunk.The salinity of this part oil-polluted water is very high, and it is high or contain a large amount of sulfate reducing bacterias to contain Cl-, when being dissolved with hazardous substances such as H2S, CO2, makes that the corrosivity of pot bottom is stronger.The 2nd, the temperature in the eliminator is higher, and miscellaneous part during with the tank body welding galvanic couple factor of formation all will aggravate its corrosion.The 3rd, the corrosion that concentration cell caused on tank skin bottom oil, the water termination.
Cathodic protection is a kind of effective ways of controlling steel storage tank and corrosive pipeline, and it has effectively remedied holiday and the corrosion that causes, can prolong the application life of storage tank greatly.
In the past the eliminator inwall was generally adopted the galvanic anode protection method; anode multiselect aluminum alloy anode; but the eliminator inner wall temperature is higher; the complicated component of inwall connate water; it is acid or alkaline that water quality might be, and aluminium is amphoteric metal, not only can be dissolved in acid; can also be dissolved in alkali, so no matter water quality is acid or alkalescence all might be quickened the consumption of aluminium anodes.So the anode loss protection time limit is shorter, generally less than promptly ruing out of half a year.Also there is the protection dead angle in anode loss protection.On the other hand, the galvanic anode protection current potential can't be measured, and protective current can't be regulated, and the length of the protection time limit can't be predicted.
Three, summary of the invention
The purpose of this utility model provides a kind of oil water separator inwall cathode protection device, solves the especially bottom race oil leakage oil that causes of seriously corroded of above-described oil water separator inwall, the problem of influence safety in production.
The technical solution of the utility model realizes in the following manner:
The utility model is by oil water separator; titanium parent tube shape Mixed Metal Oxide Coated Titanium Anodes; silver/silver chlorate reference electrode; the anode cable junction box; the reference electrode joint-box; potentiostat; cable; sealing flange and safe Matheson and Dresser joint are formed; it is characterized in that titanium parent tube shape Mixed Metal Oxide Coated Titanium Anodes establishes some; be fixed on the top, the end of horizontal or vertical oil water separator with support level; silver/silver chlorate reference electrode is established some; be fixed on below the oil-water interfaces line with support level; the cable of titanium parent tube shape Mixed Metal Oxide Coated Titanium Anodes and silver/silver chlorate reference electrode is drawn from the safety Matheson and Dresser joint and is inserted the anode cable junction box respectively and the reference electrode joint-box gathers; receive the corresponding contact of potentiostat separately again; cathode cable and zero-bit cathode cable are also received on the corresponding contact of potentiostat, form the cathodic protection circuit.
Compared with the prior art the utility model has the following advantages:
1, reasonable in design, simple in structure, easy for installation, the convenient management of the utility model.
2, the utility model has adopted titanium parent tube shape Mixed Metal Oxide Coated Titanium Anodes and silver/silver chlorate reference electrode, and is anti-oxidant anticorrosive, the application life of improving this device.
3, the utility model cathodic protection effect is remarkable, has improved the application life of oil eliminator, saves the replacing and the maintenance cost of oil water separator.

Five, the specific embodiment
For further disclosing the technical solution of the utility model,, be described in detail by embodiment below in conjunction with Figure of description:
A kind of oil water separator inwall cathode protection device is made up of oil water separator 1, titanium parent tube shape Mixed Metal Oxide Coated Titanium Anodes 3, silver/silver chlorate reference electrode 4, anode cable junction box 5, reference electrode joint-box 6, potentiostat 7, cable 9, sealing flange 10 and safe leakproof connector lug 11.Titanium parent tube shape mixes full oxide anode 3 and establishes some; be fixed on the top, the end of horizontal or vertical oil water separator 1 with support level; silver/silver chlorate reference electrode 4 is established some; be fixed on the oil-water interfaces line below 2 with support level; the cable of titanium parent tube shape Mixed Metal Oxide Coated Titanium Anodes and silver/silver chlorate ginseng electrode passes separator wall 8; draw from sealing flange 10 and safe Matheson and Dresser joint 11 and to insert anode cable junction box 5 respectively and ginseng electrode cable junction box 6 gathers; receive the contact of the correspondence of potentiostat 7 separately again; cathode cable and zero-bit cathode cable are also received on the corresponding contact of potentiostat, form the cathodic protection loop.
