Tungsten Oxide Reduction With Hydrogen Purification Drying Tower

This utility model discloses a reduction of the tungsten oxide with hydrogen purification drying tower, the tower is provided with the drying air inlet hydrogen gas to the upper end portion is provided with a hydrogen outlet at a lower end portion provided in the dry hydrogen gas with an adsorbent layer inlet between the inlet and the outlet, wherein the dry hydrogen adsorbent layer is set to three, each interval, and each height of less than 1.5 m. Wherein the adsorbent layer is a dry hydrogen or a molecular sieve layer of the silicone rubber layer.

The utility model is to abandon the prior art using only one drying tower height of more than 1.5 m in the dry hydrogen adsorbent layers. The utility model is in the drying tower spaced three layers of silica gel layer or molecular sieves, and the height is less than 1.5 meters each. After drying tower above structural transformation dried after purification of hydrogen dew point significantly lower steady state. And the production of tungsten carbide powder uniform thickness of coarse particles and fine particles are more uniform.
