Abstract
The utility model relates to a pollution and damage preventing device for metal members in seawater, which avoids the shortages of nonpersistent, unreliable or unsafe efficiency for pollution and damage prevention, and high cost in the prior art. Except that a copper aluminium anode is arranged, the anode is positioned in the seawater after the metal of titanium coating ruthenium and the metal of titanium coating iridium are electrically connected with the anode of a direct current power supply. The antitoxic property of the marine life is fundamentally destroyed by the generated synergy type mixing action. The efficiency for pollution and damage prevention is ensured to be established and lasted. The utility model has the characteristics of safe use, low cost and reliable work.
Description
The utility model is the anti-fouling device of hardware in a kind of seawater, it belongs to the electrolyzer field, the device that particularly relates to electrolysis heavy metal in seawater, it by the positive and negative electrode of direct supply respectively with seawater in copper anode, aluminum anode and hardware be electrically connected mutually and form.
People are in order to prevent hardware such as the Offshore Units such as hull, drilling unit in the seawater at present, particularly the pipeline in these facilities, filter mouth, valve, heat exchanger etc. are located to be adhered to pollution and sea water chemistry corrosion by marine organisms, the known precautionary measures of taking are that the negative pole of the hardware in the seawater with a direct current power supply is electrically connected mutually, to also place seawater with bar-shaped copper anode and the aluminum anode that this positive source is electrically connected mutually in addition, utilize seawater as electrolytic solution, discharge by electrolytic action that cupric ion is antifouling, to discharge aluminium hydroxide anticorrosion.Weak point is this device along with the passing of duration of service, will make marine organisms produce the toxin immunity adventitia, has weakened its antifouling ability greatly; For this reason, the way that adopts indirect type spray chlorine is arranged also, but this there is the problem that increases with cost safe in utilization again.In addition, bar-shaped anode commonly used in use also has defect, and the one, softer because of the material of copper, aluminium, and the screwing force between the anode flange that fixes is limited, makes its mutual poor sealing, easily causes the seawater seepage to advance in the cabin; The 2nd, electrolysis also takes place in bar-shaped anodic root when electrolysis, and this will make bath voltage be difficult to control, very easily cause whole anodic electrolyzing rate shakiness, and excessive cupric ion also can increase the weight of the erosion corrosion to hardware, the also easy early failure inefficacy of anode itself.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and the anti-fouling device of hardware in lasting, safe in utilization, the reliable seawater of a kind of anti-fouling effect is provided.
The purpose of this utility model can reach by following measure: titanium-based metal is electrically connected mutually with the positive pole of direct supply is placed in the seawater; Titanium substrate anode produces clorox and chlorine after the electrolysis in seawater, with cupric ion, aluminum ion generation mixing effect that copper anode, aluminum anode discharge, the hostile environment that had both caused marine organisms to survive has carried out anticorrosion to hardware again simultaneously.
The purpose of this utility model can also reach by following measure: titanium substrate anode can be made bar-shaped increasing electrolytic surface-area, for increasing titanium substrate anode work-ing life and reducing cost, metallizing ruthenium or iridium thereon.Bar-shaped copper, aluminium, titanium substrate anode all are fastenedly connected anode flange by transition conductor and anode rod constitutes, and transition conductor solves water tightness problems with the desirable identical matter material of flange.Simultaneously be covered with insulation layer so that the bath voltage during electrolysis is controlled, guarantee that anode rod can stablize electrolysis in the part that contacts with seawater, anode flange of transition conductor.For making each anode can not bump disconnection because of mishap and connect cable in transportation and use, an end that is connected with anode flange at transition conductor is equipped with the anti-collision cover of cap shape, and the side of cover is provided with cable aperture.
The utility model has following advantage compared to existing technology:
1. the mixing effect of installing the cooperating type that is produced can fundamentally be destroyed the antitoxic immunity ability of marine life, and the establishment of guaranteeing anti-fouling effect is with lasting;
2. the adding of the titanium substrate anode concentration that make to produce available chlorine only need reach 1/10th of indirect type spray chlorine method and gets final product, as long as and copper ion concentration also reaches antifouling index 1.5 * 10
-32/3rds of PPm just can well bring into play antifouling effect, the working current of aluminum anode and discharge ionic concentration and also reduce greatly, thus use not only safety but also reduced cost;
3. by adopting transition conductor and anti-collision cover, increase the anodic installation strength, guaranteed watertightness, and the may command bath voltage, make the anodic stabilization electrolysis, guarantee anti-fouling effect and improved reliability.
Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of basic structure synoptic diagram that the utility model is loaded on the pipeline opening place.
Fig. 2 is a kind of semi-section basic structure of anodic synoptic diagram in the utility model.
With reference to Fig. 1, Fig. 2, the positive and negative electrode of direct supply 4 respectively with seawater 0 in copper anode 1, aluminum anode 2, titanium substrate anode 3 and hardware 5 be electrically connected mutually.The transition conductor 8 that the part that contacts with seawater 0, anode flange 7 is covered with insulation layer 12 is fixed on the anode flange 7 by nut 10, anode rod 9 is connected with the screw thread of transition conductor 8 on it, and anti-collision cover 6 is loaded on through bolt 11 and plays watertight, anti-collision and electric action on the anode flange 7.
When power supply 4 respectively to copper anode 1, aluminum anode 2 provide milliampere level, when titanium substrate anode 3 provides working current about 2 amperes, the utility model promptly begins to bring into play anti-fouling effect.
