| titleOfInvention | Tungsten hexafluoride preparation device capable of improving raw material utilization rate |
| abstract | The utility model relates to a tungsten hexafluoride preparation device capable of improving the utilization rate of raw materials, and belongs to the technical field of tungsten hexafluoride preparation. The device comprises a recovery tank, a fluidized bed reactor, a purge gas pipe, a condenser, a collecting tank, a compressor, a buffer tank, a fluorine-containing mixed gas tank and a feeding mechanism. Before the tungsten hexafluoride preparation, under the even gas tray effect in fluidized bed reactor, the sweeping gas can evenly divide and blow off, the sweeping gas sweeps and evacuates the fluidized bed reactor inside, when preparing tungsten hexafluoride, the take-up (stock) pan can avoid the tungsten powder deposit can't participate in the reaction in fluidized bed reactor bottom, guarantee the tungsten powder fully react, and utilize the filter disc to filter the tungsten powder, avoid the tungsten powder to get into inside the first pipeline along with gas, the utilization ratio of raw materials has been improved, also make the tungsten hexafluoride purity that generates high, tungsten hexafluoride preparation back, utilize the sweeping gas of sweeping the trachea to carry out the pulsed blowback, make the tungsten powder attached on the filter disc blown down, the recovery tank is retrieved, it is extravagant to reduce the material. |
