Electricity is generated through a cycle in which the treated condensate is removed by a device and then heated again to convert it into steam.

It usually consists of a regeneration system for extracting, separating and regenerating the used mixed ion exchange resin from the water tower.

であり、１１はバツフルプレートを示す。 Therefore, the water tower used in the condensate desalination equipment is a transfer pipe for transporting the used mixed ion exchange resin to the regeneration system, and a pipe for receiving the regenerated mixed ion exchange resin from the regeneration system. In addition, it is necessary to install an inlet/outlet pipe for condensate to flow the condensate into the mixed ion exchange resin packed bed filled in the water tower and to drain the treated water. It won't happen. In addition, especially in water towers that treat condensate in nuclear power plants, in order to prevent the mixed ion exchange resin packed bed from being partially eroded by high-velocity, turbulent condensate, A rectifying plate is installed on the freeboard above the packed bed to rectify the flow of condensate. Figure 2 shows a schematic cross-sectional view of a conventional water tower. A screen 2 for passing water is attached, and a resin slurry take-out pipe 3 is connected to approximately the center of the screen 2, and a condensate inflow pipe 4 and a condensate outflow pipe 5 are connected to the upper and lower parts of the water tower 1, respectively. Then, a rectifying plate 7 is installed on the free board above the packed bed of mixed ion exchange resin 6 to be filled in the water tower 1, and a resin slurry supply pipe 8 is further provided passing through the rectifying plate 7. A transfer water introduction pipe 10 having a distributor 9 is provided above the rectifying plate 7, and 11 indicates a baffle plate.

脂をスラリー状で取り出すものである。 When filling the water tower 1 with mixed ion exchange resin 6, a specified amount of mixed ion exchange resin 6 is supplied from the resin slurry supply pipe 8, and when condensate is treated, the condensate is supplied from the condensate inlet pipe 4. inflow,
The baffle plate 11 cushions the inflow impact of condensate, the rectifier plate 7 straightens the flow of condensate, and the condensate that has passed through the mixed ion exchange resin 6 flows out from the condensate outflow pipe 5 through the screen 2. When the mixed ion exchange resin 6 has reached the end point of water flow and is to be taken out, the transferred water is supplied from the transferred water introduction pipe 10, and the distributed water is showered down by the distributor 9 to remove the mixed ion exchange resin 6. The mixed ion exchange resin is taken out in the form of a slurry from the resin slurry take-out pipe 3 while breaking up the packed bed.

面が平坦とならないという欠点を有している。<Problems to be solved by the invention> However, conventional water towers have the following drawbacks. That is, as shown in FIG. 2, since the resin slurry supply pipe 8 is installed off the center of the water tower 1, the mixed ion exchange resin 6 is evenly distributed in the water tower 1 when it is filled with the mixed ion exchange resin 6. The resin 6 cannot be supplied, and the upper surface of the filled layer after filling is not flat as shown in FIG. 2, which is a drawback.

若干増加するという問題がある。 Furthermore, since the transfer water introduction pipe 10 is installed above the rectifier plate 7, even if the transfer water is supplied in a shower form from the distributor 9 when taking out the mixed ion exchange resin 6, the shower water will be rectified. It collides with the plate 7 and obstructs the shower effect. Therefore, there is a drawback that a small amount of the mixed ion exchange resin (indicated by the shaded area) remains particularly at the lower peripheral edge of the water tower after being transferred. If the packed bed of mixed ion exchange resin 6 is not flat as shown in Figure 2, the ion exchange action in the packed mixed ion exchange resin will not proceed evenly, which will cause problems in terms of effective use of the packed mixed ion exchange resin 6. Furthermore, if a small amount of the mixed ion exchange resin 6 remains, there is a problem that the amount of impurity ions leaking into the condensate water will increase slightly.

通水塔に関するものである。<Means for Solving the Problems> The present invention solves the drawbacks of conventional water towers, and when filling the water tower with mixed ion exchange resin, the surface of the resin after filling is made flat and the water tower is free from the water tower. The purpose is to provide a water tower that does not leave mixed ion exchange resin in the water tower when taking out the mixed ion exchange resin, and a rectifier plate is installed on the free board above the ion exchange resin packed bed. In the water tower of the condensate desalination equipment, which allows the rectified condensate to pass through the packed bed, the resin slurry/transfer water inlet pipe is passed through the rectifier plate to approximately the center of the water tower. The lower end opening of the inlet pipe is located in the freeboard below the rectifying plate, and the upper end of the inlet pipe is attached to the buttful plate of the condensate inlet provided in the center of the upper part of the water tower. The present invention also relates to a water tower of a condensate desalination apparatus, characterized in that a resin slurry/transfer water supply pipe leading to the outside of the water tower is branched and connected to the introduction pipe.

様である。 When treating condensate in the present invention, condensate flows in from the condensate inflow pipe 4, and the buffer plate 11 cushions the impact of the condensate flowing in, and the rectifier plate 7 straightens the flow of condensate. The condensate is passed through a layer of mixed ion exchange resin 6 to remove ions and suspended solids in the condensate, and the treated condensate is discharged from the condensate outflow pipe 5 through the screen 2. Condensate treatment is exactly the same as in conventional water towers.

ない。 That is, the valve 16 is opened and the transfer water is introduced from the opening 13 of the resin slurry/transfer water introduction pipe (hereinafter referred to as the introduction pipe) 12 via the resin slurry/transfer water supply pipe (hereinafter referred to as the supply pipe) 15 . By introducing such transfer water, the filled mixed ion exchange resin 6 is transferred from the lower part in the form of a slurry from the resin slurry take-out pipe 3, but in the present invention, the opening of the introduction pipe 12 that supplies the transfer water is Part 1
3 is located at the lower part of the rectifier plate 7, the flow of the transferred water is not hindered, and the transferred water falling from the opening 13 hits the screen 2 with force, especially just before the end of transfer. , and due to the collision, the water tower 1 along the screen 2
Since a water flow is generated toward the periphery of the water tower, this water flow effectively breaks down the mixed ion exchange resin present at the periphery of the lower end of the water tower, so that the mixed ion exchange resin remains at the periphery of the lower end of the water tower. Never.
