PURPOSE:To make the service life of ion exchange resin ascertainable as well as to aim at improvement in both economic and efficient properties, by installing both arithmetic and display units for operating and displaying the extent of residual ion exchange capacity in ion exchange resin on the basis of the measured value of each conductive degree and exchange flow of a dielectric fluid before and after the ion exchange. CONSTITUTION:When a dielectric fluid 2 inside a fluid tank 1 becomes more than the setting conductive degree, a solenoid valve 7 is opened and the dielectric fluid is fed to ion exchange resin 8, thus ion exchange in the dielectric fluid takes place. Next, an arithmetic unit 11 operates the value of ion exchange capacity from the value of a conductive degree of the dielectric fluid before the ion exchange and the value of the conductive degree of the dielectric fluid immediately after the ion exchange, and remaining operating time till reaching the service life of the ion exchange resin is found out of both values of ion exchange capacity and ion exchange flow on the basis of a life characteristic inherent in the ion exchange resin. And, At a display unit 12, the ion exchange capacity found by the arithmetic unit 11 and the residual operating time of up to the service life are displayed, informing an operator of this fact. Thus, the service life of the ion exchange resin is clarified whereby operation is performable so economically and efficiently. |
