Abstract

PURPOSE:To regenerate a chelating agent by adsorbing dissolved scale on an ion exchange resin and reduce scale removal time by supplying the chelating agent and the cation exchange resin as a cleaning agent in cleaning away of scale. CONSTITUTION:A circulation system of pipings 2, 6, 8, 7 is provided to a cleaning object 1. Next, a chelating agent soln. from the line 8 is mixed with the ion exchange resin from the line 6 in an ejector type mixer 5 by means of a pump 4, and is supplied to the object 1 through the line 7. The washing liquid removing scale flows through the line 2 into a solid-liquid separator 5, where it is separated to the chelating agent soln. and the ion exchange resin. The chelating agent soln. is separated to the line 8 and the ion exchange resin to the line 6. At this time, the cation exchange resin adsorbing the scale components of the chelating agent soln. is withdrawn from the line 9 and is regenerated. The regenerated ion exchange resin is replenished through the line 10 and is mixed with the regenerated chelating agent soln. in the mixer 5, whereby the mixture is used for the scale removal.
