| titleOfInvention | A kind of process unit and method for cationic ion-exchange resin production |
| abstract | The invention discloses a kind of process unit and method for cationic ion-exchange resin production, including the sulfur trioxide being sequentially connected with to add system, sulfonating reaction kettle and washing kettle, in addition to acid solution recovery and resin washing system：Acid solution recovery system includes mother liquor acid, concentrated acid and dilute acid recovery system in parallel, and import is connected with the liquid outlet of washing kettle；The outlet of mother liquor acid recovery system is connected with the mother liquor acid entrance of sulfonating reaction kettle；Concentrated acid recovery system and dilute acid recovery system outlet are connected with the acid and pure water entrance of washing kettle；Resin washing system includes pure water system and drainage trap, pure water system inlets are connected with washing kettle liquid outlet, export and be connected with washing kettle acid and pure water entrance, and the import of drainage trap is connected with the resin discharging opening of washing kettle, exports and is connected with the waste water inlet of pure water system.The more traditional sulfuric acid sulfonation method of the outer waste discharge acid of the present invention reduces more than 85%, and outer row's acid waste water reduces more than 90%. |
