本発明は、放射能濃度が比較的高い放射性流体を取扱う
吸着装置、例えばイオン交換装置、或いは濾過装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an adsorption device, such as an ion exchange device or a filtration device, that handles a radioactive fluid with a relatively high radioactivity concentration.

員の被曝あるいは作業効率の低下をまねていた。In conventional devices of this kind, an adsorption tower is installed in a cell surrounded by a shielding body such as a thick plate, and radioactive fluid is processed while shielding high-level radiation. On the other hand, when it is necessary to replace the adsorbent, the entire adsorption tower filled with the adsorbent is replaced for reasons such as preventing the spread of radioactive substances or simplifying the system. Not only is it necessary to manufacture an adsorption tower each time the adsorption tower is replaced, but it is also unavoidable to work inside the shield, such as disconnecting the adsorption tower and piping, or to remove a part of the shield. This was imitating the radiation exposure of personnel and a decline in work efficiency.
この種の従来の吸着器について第６図に基いて説明する

再び原水の処理を行っている。It is necessary to introduce the radioactive fluid through the raw water introduction pipe 7 and bring it into contact with the adsorbent 2 in the adsorption tower 1 to remove radioactive substances, and after the adsorbent 2 reaches saturation, to replace the adsorbent 2. In this case, after removing the 7 langes 51°3Z 41, the adsorption tower 1
together with the shield (lift it up with a chain, etc., and carry it over the bit where the adsorption tower is to be disposed of), then remove a part of the shield, remove the 7 langes 3° 3.4, and then lift the adsorption tower with the chain 11. Lower it into the lower bit and discard it.Then, lift a new adsorption tower containing new adsorbent into the shield using a chain, close the 7 langes 3, 3゜4, etc., and place the shield in the designated position. I carried it along with the 7 lunge 5Z 51.41 and started treating the raw water again.

。In this case, 7 lunges! , 45.4, workers must enter the shield or remove part of the shield to carry out the work.There is a risk of rounding exposure, and it may be adsorbed together with the saturated adsorbent. Because the tower will be disposed of along with it,
It was also uneconomical because an adsorption tower had to be created each time.

供することを目的とするものである。The present invention has been made to eliminate the drawbacks of the prior art, and includes storing an adsorbent in a cartridge-type container and inserting it into an adsorption tower, and making the upper wall of the Kll cover also serve as the upper cover of the adsorption tower. In addition, it is constructed so that the cartridge can be attached and removed together with the shield from the adsorption tower, and the work to disconnect each piping can be done outside the shield, and it is constructed so that only one cartridge can be replaced. The object of the present invention is to provide an adsorber that can significantly reduce the manufacturing cost, that is, the operating cost of the tower.

理を行うものである。When the adsorbent 2 reaches saturation, remove the 7-lunge s% sl on the raw water inlet pipe 7 and the vent 8, and remove the nut at the top of the through port 13 to shield only the adsorption tower 1. After being separated from the body 1o and the cartridge 2', the shielding body 10 is lifted up together with the cartridge 2' by a chain (not shown), and after being carried onto a cartridge disposal bit, the cartridge 2' is lifted up from the shielding body 10. After cutting it off and discarding it in a bit, a new cartridge is set and attached together with the adsorption tower IKm shield, and the raw water is processed again.

１３（第３図参照）罠より締めつけられている。As shown in FIGS. 2 and 3, the cartridge 2' containing the adsorbent 2 is inserted into the adsorption tower 1, and the upper 7 langes 12 of the cartridge are attached to the upper wall 1G of the shield.
The upper part 7 of the adsorption tower 7 is tightened from above and below by a through bolt 13 (see Figure 3).

When the sl is removed, the shield upper wall 10' and the cartridge 2' are separated from each other as shown in FIG.
Since the flange 6 is tightened by the lifting bolt 14, the shield and the cartridge 2' are separated from the adsorption tower 2. Next, the shield, together with the cartridge, is lifted up by a lifting fitting attached to the shield and moved to the upper part of the waste storage pit using a crane or the like. During movement, radiation from the cartridge is blocked by a shield. After the movement is complete, remove the nut 14' of the lifting bolt 14 (see Figure 5) from the top of the shield, and the cartridge 2' will be placed above the shield.
(See Figure 4) It will be suspended from K.

When tightened, it becomes possible to process raw water.

の材料とすることができる。The part of the shield that also serves as the upper cover 5 of the adsorption tower (see Figure 6), that is, the upper wall 10' of the shield, comes into contact with the radioactive fluid, so it must be made of a corrosion-resistant material such as stainless steel. Since the body does not come into contact with liquid, it can be made of low-cost materials such as carbon steel.

が第５図に示すものである。When using a cartridge with the structure shown in Figure 2, it is necessary to introduce pressurized air or the like from the top of the cartridge when replacing it to thoroughly drain water, but even in this case, droplets may come out from the bottom of the cartridge while the bit salt is being transferred. It is difficult to completely prevent falling. The solution to this problem is shown in FIG.

は第２図に関し説明したのと同じである。In the system shown in Fig. 5, the cartridge itself is an independent pressure vessel, raw water is introduced from the top of the cartridge as in the case shown in Fig. 2, and treated water is passed through the water collection plate at the bottom of the cartridge and into the center of the cartridge. It is configured so that it flows into the center pipe 20 provided at the top of the cartridge, becomes an upward flow, and flows out from the top of the cartridge.
is the same as explained in connection with FIG.
