Description

Technical Field

[0002] Ammonium rhenate is an inorganic compound soluble in ethanol and water. Industrially, it is an important raw material for the preparation of metallic rhenium. Some ammonium rhenate solutions contain a certain amount of potassium impurities. To improve the purity of ammonium rhenate solutions, this potassium impurity must be removed.

[0003] At present, the removal of potassium impurities in ammonium rhenate solution is often done by ion exchange, and the ion exchange method often uses cationic resins. The potassium ions in the ammonium rhenate solution are fully replaced by hydrogen ions or sodium ions on the cationic resin to achieve the removal of potassium ions.

[0004] Cationic resin is usually filled in an exchange column, and liquid inlet and outlet interfaces are respectively set at the upper and lower ends of the exchange column, and the interfaces are connected to the pipeline. In order to increase the connection range, multiple interfaces of different specifications are usually set. After connecting to one of the interfaces, the remaining unused interfaces need to be sealed (sealed with a sealing cover or a customized seal). When it is necessary to switch to another specification of pipeline connection, it is necessary to remove the sealing cover or seal on the used interface, and find another sealing cover or seal to seal the interface that has lost connection. Over time, some seals or sealing covers are prone to loss. Utility Model Content
