Abstract
PURPOSE: To reduce the amount of waste liquid by washing effectively title resin by repeating steps of supplying a specified amount of water, removing clad, discharging water and back-washing a drain pipe while scrubbing the resin placed in a regeneration tower with air.
CONSTITUTION: An ion exchange resin contaminated by a desalting treatment of condensate is introduced in slurry state into a regeneration tower 9, and charged to a level of the lower part of a freeboard drain pipe 11. Then the scrubbing of the resin is carried out by opening a vent valve 1, an air valve 4 for scrubbing and a water valve 3, and the clad on surface is removed. By continuing the above operation, a water-injection amount is so controlled that water volume in the upper part of the pipe 11 becomes roughly equivalent to that in the lower part of the pipe 11. Then a valve 7 is opened. Water present in the upper part of the pipe 11 is discharged from the pipe 11 by means of air pressure within the tower. Back wash within the pipe 11 is carried out by introducing water or air from a back wash valve 6 into the pipe 11. The above three steps are repeated several times.
