| titleOfInvention | Brine refining method and device for extracting lithium from salt lake |
| abstract | The invention relates to the technical field of salt chemical engineering, and relates to and discloses a brine refining method for extracting lithium from a salt lake. The method adopts the nanofiltration device to respectively remove sulfate and carbonate in the brine by controlling pH, reduces the operating pressure of the nanofiltration system, and improves the recovery rate of lithium by washing the concentrated water. The invention also discloses a brine refining device for extracting lithium from the salt lake. The device comprises two or more membrane separation modules and a concentrated water adjusting device, and is provided with a water inlet and concentrated water balance valve group, so that the operation of cutting in and cutting out a single membrane separation module in the device can be realized under the condition that the normal high-pressure production operation of the device system does not need to be stopped, the continuous production is really realized, and the auxiliary production time is saved. The dense water adjusting device can realize precise adjustment, step down in sections and reduce the noise of the pipeline. The invention can realize the recovery of salt lake resources and improve the continuity and stability of the operation of the device. |
