用いるとよい。<Operation> Next, the operation of the ion exchange tower of the present invention will be described with reference to FIGS. 1 and 2. In the present invention, when a specified amount of ion-exchange resin is put in the ion-exchange tower 1, the water is appropriately drained from the drain port 9 at the bottom of the tower while adding the ion-exchange resin slurry from the inlet 2 as in the conventional case. To do. When such an operation is continued, the settling surface A of the ion exchange resin 10 is formed in the tower as described above, and the settling surface A gradually rises in the ion exchange tower 1 as the amount of the slurry charged increases. . On the other hand, a laser beam emitting section 5 provided outside the transparent plate 4 always emits a laser beam, and a laser beam receiving section 6 provided outside the other transparent plate 4 emits the laser beam. Whether or not it reaches the light receiving unit 6 is constantly monitored. When the ion-exchange resin slurry is continuously supplied in such a state, a substance that blocks the laser beam, that is, a layer of the ion-exchange resin is formed on the optical path B of the laser beam connecting the laser beam emitting section 5 and the laser beam receiving section 6. In the nonexistent state, the laser beam emitted from the light emitting unit 5 travels straight in the ion exchange tower 1. Therefore, by detecting the laser beam at the laser beam receiving unit 6, a predetermined amount of the laser beam still remains in the ion exchange tower 1. It can be known that the ion exchange resin has not been added. Then, when the setting surface 4 of the ion exchange resin gradually rises and reaches the optical path B of the laser beam and the laser beam emitted from the light emitting section 5 is blocked, the light receiving section 6 does not receive the laser beam. Therefore, by stopping the inflow of the ion exchange resin slurry at the same time that the light receiving section 6 stops receiving the laser beam, a specified amount of the ion exchange resin can be received in the ion exchange tower 1. Since the laser beam has a remarkably strong transmittance as compared with visible light, for example, even if the water on the set surface is turbid or colored due to the suspended substance, it can be transmitted. FIG. 3 is a plan view of an ion exchange tower showing another embodiment of the present invention, in which a pair of laser beam emitting parts 5 fitted into the reference position of the tower wall of the ion exchange tower 1 and the other transparent plate 4 are shown. An example of an ion exchange column is shown in which two sets of the settling surface detection device including the laser beam receiving unit 6 provided on the outside are provided at positions moved by approximately 90 degrees. in this way,
When two sets of the settling surface detection devices are provided at positions moved by approximately 90 degrees, by stopping the inflow of the ion exchange resin slurry when the respective light receiving parts 6 and 6 stop receiving laser beams at the same time, Even if the ion-exchange resin settling surface A is inclined, the specified amount of ion-exchange resin can be accurately received. The laser beam emitting section used in the present invention may be any one as long as it can emit a laser beam, but normally a semiconductor laser emitting device capable of emitting a laser beam having a wavelength of about 780 nm is preferably used.

ことが可能となるという効果も奏する。<Effects> As described above, the ion exchange tower of the present invention uses a laser beam, which is significantly superior to ordinary visible light in both transmission and non-diffusion, as a means for detecting the ion-exchange resin deposition surface. Even if the ion-exchange resin slurry is cloudy or colored, it is not blocked like visible light, and even in such a case, the ion-exchange resin The settling surface can be detected and thus a defined amount of ion exchange resin can be accurately received in the ion exchange column. Further, as shown in FIG. 3, in the case of two sets of ion exchange towers provided at the position where the settling surface detection device is moved by about 90 degrees, even if the settling surface of the ion exchange resin is inclined. Even in such a case, the specified amount of the ion exchange resin can be accurately received. Further, in the conventional ion exchange tower, since the deposition surface of the ion exchange resin was visually detected, it was not possible to automatically detect that the specified amount of ion exchange resin was received. According to the ion exchange tower of the present invention, there is also an effect that it is possible to automatically detect the settling surface.
