摘要： PROBLEM TO BE SOLVED: To provide a condensate demineralization method and device which can form a sound mixed bed without concentration of cation resin on the resin bed bottom of a demineralizer during resin return after back washing. SOLUTION: In the method for demineralizing the condensate by using ion-exchange resins, the condensate is made to flow downward through the resin bed where the bottom part is filled with a part not easily separable made by selectively concentrating anion resin and cation resin of which the resin particles have terminal velocities overlapped or close to each other, and a part excluding the top part and the bottom part is filled with a mixed bed of the anion resin and the cation resin. It is desired that the part not easily separable that fills the resin bed bottom is a part of the mixed layer of resin particles which are concentrated near the separation face of the anion resin and cation resin used for condensate demineralization treatment and having a Gaussian distribution when both resins are back washed.

摘要： PURPOSE:To establish the condition for regenerating a desalter by backwashing or chemicals in the removal of suspended impurities using an ion-exchange resin. CONSTITUTION:The grainy cation-exchange resin and anion-exchange resin having a granular bonding structure on the surface layer are mixed to form the mixed bed which is placed in a desalter. The suspended impurities in water are removed and filtered off by the desalter. In this method, the desalter is backwashed and regenerated when the differential pressure of the resin bed increases to 0.2-0.8kg/cm due to the collection of the suspended impurities, and chemicals are passed through the bed to regenerate the bed when the suspended impurity concn. increases to >=1.5ppb at the inlet of the desalter.

摘要： PURPOSE:To strengthen the secondary system water treatment capacity of a PWR type atomic power plant by forming a mixed bed of resin in the given range in which water content of resin is increased more than the standard value of existing gel type resin in the filter desalting process by means of cation-anion exchange resin. CONSTITUTION:When the secondary system water of a PWR atomic power plant is treated, a mixed bed composed of laminated cation exchange resin in the range (55-75%) of water content increased more than the standard value (45-55%) of gel type resin is formed on an upper layer section of a mixed bed of existing ion exchange resin in the filter desalting process by means of the mixed bed composed of grain or powder-like cation and anion exchange resin. As the water content of cation-anion exchange resin is higher compared with the existing mixed bed type filter desalting process, affinity with clad of high hydrophilic properties is high and clad separation effect is large, and water of high purity degree with lower clad concentration can be prepared at the time of filter desalting operation.
