Description

Technical Field

[0001] This utility model relates to the field of vanadium precipitation technology, specifically to a pH control mechanism for a vanadium precipitation stirring tank. Background Technology

[0002] "Vanadium precipitation" refers to the process of precipitating vanadium from a solution;

[0003] pH-adjusted precipitation method: Principle: Under alkaline conditions, vanadium precipitates as polyvanadates. Procedure: Adjust the pH of the vanadium-containing solution to 8-9 using NaOH or ammonia. Heating promotes the reaction, producing yellow ammonium vanadate or sodium vanadate precipitates.

[0004] When processing vanadium-containing solutions, if the pH is found to be too high, it needs to be adjusted to a more suitable range, such as the pH range of 8-9 commonly used in vanadium precipitation. Common neutralizing agents include acids such as sulfuric acid, hydrochloric acid, and nitric acid, or acidic salts such as ammonium sulfate and ammonium chloride. Alternatively, the pH can be adjusted by diluting the solution or by introducing carbon dioxide.

[0005] Currently, vanadium precipitation is typically performed inside a stirred tank, also known as a mixing vessel. Acid or alkali solutions are added to maintain a suitable pH between 8 and 9, which facilitates vanadium precipitation. However, current methods often involve manually adding the prepared solution to the stirred tank, leading to poor pH control and reduced precipitation efficiency. Therefore, we propose a pH control mechanism for the vanadium precipitation stirred tank. Utility Model Content
