Description

Technical Field

[0001] This utility model belongs to the field of electrostatic decontamination technology, specifically relating to an electrostatic decontamination device for offshore platforms. Background Technology

[0002] Offshore platforms, especially oil and gas extraction platforms, face serious pollution problems during long-term operation. These pollution sources include oil spills, corrosion products, and microbial deposits, which not only affect the normal operation of equipment but may also cause serious harm to the marine environment.

Mechanical cleaning, which involves high-pressure water guns or manual cleaning, is inefficient, requires frequent operation, and is ineffective at cleaning complex structures. Chemical cleaning, on the other hand, can easily pollute marine ecosystems, thus causing great harm to the environment. Utility Model Content

The surface of the hydrogen degassing tank 3 is equipped with an exhaust pipe 16, and the top of the hydrogen degassing tank 3 is equipped with a hydrogen pipeline 17 and a feed pipe 18. Supply pipes 21 are installed on both sides of the surface of the hydrogen fuel cell 4. Through the coordinated use of the electrolyzer 2, the hydrogen degassing tank 3 and the hydrogen fuel cell 4, active substances are generated in situ by electrolyzing seawater, preventing secondary pollution and meeting environmental protection regulations. It also prevents hydrogen explosion emissions and automatically neutralizes chlorine, avoiding marine ecological risks. It can quickly and effectively remove oil, rust and other deposits from metal surfaces, significantly improving the working efficiency of the device and increasing the service life of the ship.

[0025] Specifically, a cover plate 7 is rotatably connected to the surface of the dosing funnel 6, and a lifting knob 8 is fixedly connected to the surface of the cover plate 7.

[0026] In a specific embodiment of this utility model, the lifting knob 8 allows the operator to hold the knob 8 and move the cover plate 7 to open and close the dosing funnel 6.

[0027] Specifically, a first support plate 12 is installed on the upper surface of the bracket 1, and a first limit buckle 13 adapted to the booster pump 9 is provided on the surface of the first support plate 12.

[0028] In a specific embodiment of this utility model, the first support plate 12 and the first limiting buckle 13 are used together to facilitate the limiting of the booster pump 9, thereby reducing the probability of the booster pump 9 moving during operation.

[0029] Specifically, a second support plate 14 is installed on the upper surface of the bracket 1, and the surface of the second support plate 14 is provided with a second limiting buckle 15 adapted to the sodium hypochlorite adding pipe 5.

[0030] In a specific embodiment of this utility model, the second support plate 14 and the second limiting buckle 15 are used in conjunction to facilitate the limiting of the second limiting buckle 15, thereby reducing the probability of the sodium hypochlorite dosing pipe 5 moving during operation, and thus reducing the probability of sodium hypochlorite leakage.

[0031] Specifically, one end of the hydrogen pipeline 17 is connected to the hydrogen fuel cell 4, and one end of the feed pipe 18 is connected to the electrolyzer 2.

[0032] In a specific embodiment of this utility model, the hydrogen pipeline 17 is connected to the hydrogen fuel cell 4, which facilitates the entry of the gas inside the hydrogen fuel cell 4 into the hydrogen degassing tank 3.

[0035] Working principle: When the booster pump 9 is started, seawater is transported to the inside of the electrolyzer 2 through the liquid inlet pipe 10 and the liquid inlet head 11. At this time, the electrolyzer 2 electrolyzes the seawater into sodium hypochlorite and hydrogen. Then, the gas is transported to the inside of the hydrogen degassing tank 3 through the feed pipe 18. In the hydrogen degassing tank 3, liquid sodium hypochlorite and gas are separated. At the same time, hydrogen and oxygen enter the inside of the hydrogen fuel cell 4 under the action of the hydrogen pipeline 17, and produce water and energy. The energy is transported back to the inside of the electrolyzer 2 through the conveyor line 20.
