Embodiment 1
[0035] The extracorporeal countercurrent regeneration process of ion exchange resin is characterized in that: carry out according to the following steps:
[0036] A While producing soft water, continuously discharge the invalid resin from the lower part of the ion exchanger;
[0037] B. The expired resin is transported into the collection tank by spraying, the delivery liquid is discharged from the upper part of the collection tank, and the expired resin is discharged from the bottom of the collection tank and enters the regeneration tank;
[0038] C. Feed the regeneration liquid into the lower part of the regeneration tank, and the invalid resin is regenerated in countercurrent, and the regenerated resin is discharged from the bottom of the regeneration tank and enters the cleaning tank;
[0039] D Water is fed from the bottom of the cleaning tank, and the residual regeneration liquid on the regenerated resin is reversely cleaned. The cleaned regenerated resin is discharged f...
