High-purity high density blue tungsten oxide’s production equipment is determined by its production process in industry, including alkali decomposition furnace, plate and frame filter press, ion exchange column, spray drying tower and reduction furnace, etc. Industrial production of blue tungsten oxide mainly through alkali decomposition, filter, ion exchange, dry and reduction and other processes.
Production Equipment of High-purity High Density Blue Tungsten Oxide
1. Alkali decomposition furnace is mainly used in the decomposition of tungsten ore to prepare ammonium metatungstate (AMT) for dissolving tungsten into a solution.
2. A plate and frame filter press is referred to as a "membrane filter plate". It is used for the impurity removal process of sodium tungstate to produce high purity sodium tungstate.
3. Ion exchange column (mixed bed) is the cylindrical pressure vessel used for ion exchange reaction, and to remove a series of impurities of S, Mo, P, As, Ca, Cu and Sn.
4. Spray drying tower. Feed liquid of ammonium paratungstate (APT) will soon be dried under high temperature air in spray drying tower.
5. Hydrogen reduction furnace is used to reduce tungsten oxide, which mainly consists of control cabinet, furnace, pusher and gas circuit system, etc.
