| titleOfInvention | A kind of salt extraction process and salt making system |
| abstract | The present invention relates to water treatment field, discloses a kind of salt extraction process and salt making system.This method includes：Brackish water is subjected to nanofiltration separation processing, obtains nanofiltration production water and nanofiltration concentrated water；Crystallization Separation is carried out after nanofiltration concentrated water is cooled down, obtains crystallizing water outlet and crystal salt, moisture will be crystallized out as backflow crystallization water outlet and crystallization concentrated water；Concentrated water will be crystallized and the second evaporative crystallization backflow concentrated water carries out alternating temperature evaporative crystallization separating treatment, dianion salt, univalent anion salt and the second evaporative crystallization concentrated water is obtained, the second evaporative crystallization concentrated water is divided into the second evaporative crystallization backflow concentrated water and system concentrated water；Brackish water includes raw water and the crystallization water outlet that flows back, dianion salt quality degree X% in raw water<When 5%, meet R1<X/ (5 X), R1 are the volume flow ratio that crystallization concentrated water produces water with nanofiltration.The one-component salt of high-purity can be made in the method for the present invention, and investment and operating cost can be greatly reduced and improve the rate of recovery of salt. |
