Abstract
The utility model relates to a solar energy electrochemistry anti-corrosion protection device for a pipeline or a tank. The solar energy electrochemistry anti-corrosion protection device for the pipeline or the tank comprises an accumulator (2), wherein an input end of the accumulator (2) is connected with a silicon crystal solar energy battery array (1) through a line conductor, an output end of the accumulator (2) is connected with a constant potential rectifier (3) through the line conductor, one end of two end ports of the constant potential rectifier (3) is connected with an auxiliary anode (5) through a cable (4), and the other end is connected with an oil field embedded pipeline (6) through the cable (4). The device adopts the silicon crystal solar energy battery array and the accumulator for matching as a power supply of a cathode protective system, thereby guaranteeing power supply even in cloudy weather or after the sun falls, and guaranteeing that the protected pipeline or tank electric level can reach higher than -0.85V, and the solar energy electrochemistry anti-corrosion protection device has the advantages of safety, reliability, long service life, convenient operation and maintenance, none noise and none pollution, is applicable to unattended operation, and the like.
Description
Technical field:
The utility model relates to a kind of solar-electricity Chemical Preservation protector that is used for pipeline or jar.
Background technology:
At present the corrosion control measure of oil field pipe is had a variety ofly, for example change the internal structure of metal, at metallic surface protective cover, electro-chemical protection etc.But the most cost-effective corrosion control measure mainly is a tectum (coating) adds galvanic protection.Galvanic protection is divided into two kinds of galvanic anode protection and impressed current (impressed current) galvanic protections.Sacrificial anode protection is not employed during reasons such as working life weak point are often constructed at the scene and adopts because output rating is little, and the protective current variable range is little.Advantages such as and impressed current is long owing to service life, and output rating is big, and protection domain is big often are used in many pipelines, the equipment.But because the oil field pipe major part is embedded in open-air location.The there environment is abominable, can not utilize power supply, makes impressed current can not bring into play the advantage of self, makes oil field pipe can not get effective corrosionproof protection at last.
The utility model content:
In order to solve the problem in the background technology; the utility model provides a kind of solar-electricity Chemical Preservation protector that is used for pipeline or jar; the utility model is that traditional cathodic protection system is combined with device of solar generating, has avoided solving building in being in abominable, the meagrely-populated and distance between sites not convenient again predicament that does not have power supply with some valve chambers, cathodic protection station and detective pole in the oil field long distance pipeline construction of electric main far away of environment.Adopt the Nature environmental protection generating, promptly saved the energy, economical and practical again, be fit to the oil field and promote.
The technical solution of the utility model is: this solar-electricity Chemical Preservation protector that is used for pipeline or jar comprises store battery; the input terminus of store battery is connected with the silicon wafer solar battery array by lead; the output terminal of store battery is connected with potentiostat by lead; two port one ends of potentiostat are joined by cable and supplementary anode, and the other end is joined by cable and oil field ground pipeline.
The utlity model has following beneficial effect: basis is novel to replace conventional power cathode securing system with solar electrical energy generation, has broken the impressed current pipeline corrosion protection method that conventional use civil power could be realized.Have safe and reliable, advantages such as the life-span is long, running maintenance is easy, noiseless, pollution-free, suitable unmanned.And sun power sends is direct current, especially to lacking the petroleum pipe line cathodic protection system of reliable AC network on the way, its unique characteristics arranged.Characteristics are as follows: 1, do not have exhausted dangerous; 2, self power generation, non-maintaining; 3, absolute clean (nuisanceless) do not produce environment and pollutes; 4, be not subjected to the restriction of resource distribution region; 5, can generate electricity nearby in electricity consumption place; 6, energy source quality height; 7, obtain the time weak point of energy cost; 8, light weight, maintenance and easy to use.Be that a kind of environment that is applied in is abominable, can not utilize the power supply location that pipeline or jar are carried out the rot-resistant device.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-silicon wafer solar cell among the figure, 2-store battery, 3-central controller, 4-cable, 5-supplementary anode, 6-oil field ground pipeline.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in accompanying drawing 1, this adopts the supply unit of silicon wafer solar cell 1 as galvanic protection, is used power supply as cathodic protection system with silicon wafer solar battery array 1 and store battery 2.Guarantee also can guarantee power supply after the cloudy day or the sun set.Adopt 3 pairs of systems of potentiostat to control and manage, use cable 4 be connected supplementary anode 5 and protected underground oil field buried pipeline 6.Make system form a loop by soil, guarantee a protected pipeline or a jar current potential reach-more than the 0.85V.Have safe and reliable, characteristics such as the life-span is long, running maintenance is easy, noiseless, pollution-free, suitable unmanned.
