Description

Technical Field

[0001] The utility model relates to the field of tungsten-containing wastewater treatment, in particular to a tungsten-containing wastewater treatment and filtering device in tungsten smelting. Background Art

[0002] Tungsten is a metal element with the symbol W and the atomic number 74. It is in the VIB group of the sixth period of the periodic table. Since the W6+ ion has a small radius, high charge, strong polarization ability, and is easy to form complex anions, tungsten is mainly in the form of complex anions [WO4]2-, which combines with cations such as Fe2+, Mn2+, and Ca2+ in the solution to form wolframite or scheelite precipitation. The single substance is a silvery white and shiny metal with high hardness and melting point. It is not corroded by air at room temperature and has relatively stable chemical properties. The existing tungsten is often extracted through wet smelting. During the wet smelting process, some tungsten-containing wastewater is often produced, and these tungsten-containing wastewaters often need to be re-extracted through the setting of extraction processes. However, the existing tungsten-containing wastewater filtration devices are mostly equipped with reaction tanks to extract tungsten through natural precipitation. This method requires workers to frequently move outside the device because of the need for continuous addition of precipitants. At the same time, because the depth of the reaction tank is relatively deep, when adding drugs into the reaction tank, it is also easy to affect the life safety of the workers. Utility Model Content
