Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses electrolysis trough with corrosion-resistant outlet conduit of preferred embodiment, including operation platform 1, be equipped with the stair 2 that is used for going upstairs and downstairs on operation platform 1, be equipped with a plurality of cell bodies 3 on operation platform 1, the both ends of cell body 3 are equipped with anode chamber 31 and cathode chamber 32 respectively, are equipped with the ionic membrane 4 of a plurality of parallels in the cell body 3, are equipped with gasket 41 between the adjacent ionic membrane 4, are equipped with anolyte outlet conduit 5 on the anode chamber 31, and anolyte outlet conduit 5 adopts metal pipeline. And a sacrificial electrode is arranged on the anolyte outlet pipeline 5, and the electric potential of the sacrificial electrode is higher than that of the anolyte outlet pipeline 5. The anode liquid outlet pipeline 5 is connected with an anode liquid tank 6, and a grounding wire 7 is arranged between the outlet pipeline and the anode liquid tank 6. And the anolyte outlet pipeline 5 is connected with a large-current polarization rectifier 8.
The outlet pipeline of the electrolytic cell is generally a non-metal pipeline which has the defects of short service life, easy leakage, difficult maintenance and the like, but has small leakage current and no electrochemical corrosion.
The total leakage current of the electrolytic cell comprises leakage current, bypass current and stray current, after the anolyte outlet pipeline 5 is changed into a metal pipeline, the total leakage current is increased, and the electrochemical corrosion is serious, so the damage of the leakage current to the electrolytic cell is avoided by increasing the polarized rectifier 8, increasing the sacrificial electrode, grounding the system and the like. The electric tank outlet pipeline is reformed into a metal pipeline, so that the service life is prolonged, the leakage is reduced, and the maintenance is convenient.
The utility model discloses an electrolysis trough with corrosion-resistant outlet conduit reforms outlet conduit into metal pipeline, has prolonged the life of pipeline, reduces and reveals, convenient maintenance to the problem that total leakage current increases and electrochemical corrosion is serious has been solved.
The above detailed description merely describes the preferred embodiments of the present invention and does not limit the scope of the present invention. Without departing from the design concept and spirit scope of the present invention, the ordinary skilled in the art should belong to the protection scope of the present invention according to the present invention provides the text description and drawings to the various modifications, replacements and improvements made by the technical solution of the present invention. The scope of protection of the present invention is determined by the claims.
