| titleOfInvention | A kind of retracting device and its recovery method of lithium fluoride |
| abstract | The present invention relates to a kind of retracting device of lithium fluoride, including：Fluohydric acid gas pipeline：With the fluorination hydrogen source, condenser, separated and dissolved device and the absorbent lime device that are sequentially connected；Connected by fluohydric acid gas gas circuit between fluorination hydrogen source and condenser；Connected by fluohydric acid gas fluid path between condenser and separated and dissolved device；Connected by equalizing line between separated and dissolved device and absorbent lime device；The inert gas source of fluohydric acid gas gas circuit upstream, is connected with fluohydric acid gas gas circuit and/or condenser by purging branch road；The fluohydric acid gas absorption system in separated and dissolved device downstream, with the spray absorber and alkali liquor absorption tank that are sequentially connected；The negative pressure system in fluohydric acid gas absorption system downstream, with the vacuum degree control device and chemical membrane pump that are sequentially connected.The present invention also provides a kind of method for reclaiming lithium fluoride.Lithium fluoride of the purity more than 95% can be obtained using the retracting device and recovery method of the present invention, the lithium fluoride of recovery can be recycled, and realize utilization of resources. |
