Conventionally proposed methods, in which a uranium adsorption device is held on the sea surface or in the sea, and seawater passes through the adsorption layer of the uranium adsorption device, generally have the following drawbacks: Not suitable for processing.
（１） 吸着剤として２粒子状、網状、繊維状等のも

けるためには吸着層の通水断面積を非常に大きくするこ
とが必要であるので。(1) If particles, nets, fibers, etc. are used as the adsorbent, the resistance when water is passed through is large, and in order to avoid this, the cross-sectional area of the water passing through the adsorption layer must be made extremely large. Because it is necessary.

A powdered adsorbent with fi properties is used in a fluidized bed method.
通水抵抗を減らす方式も提案されているが。Methods to reduce water flow resistance have also been proposed.

置が大形になり、まだ、有効な磁場形成に大量のエネル
ギを消費する１ｉｌｌ１点がある。The device that captures the fluid adsorbent using a magnetic field and separates it from seawater has become large in size, and there is still a point where it consumes a large amount of energy to create an effective magnetic field.
このような欠点を除去するため１本発明者等は。In order to eliminate such drawbacks, the present inventors have proposed the following.

着剤の再生取扱いに手数を要する難点があった。We have proposed equipment that can efficiently extract seawater uranium (Japanese Patent Application No. 57-022816), but even with this, the cost of forming the adsorbent into a lattice shape is relatively high, and it is still difficult to recycle the adsorbent. There was a problem that required a lot of work.
本発明は、上記従来技術及び上記先願技術の難点を解消
し、ウラン吸着剤への海水接触が効率よく、かつ均一に
行われ、海水中のウランを珠
効率的に檄取でき、しかも小形で建設費の安価なウラン
採取装置を提供することを目的として提案されたもので
１粒子状吸着剤と海水とを混合させる吸着ゾーンと上下
方向に配置した複数個の吸着剤沈積床を具備した吸着剤
沈降分離ゾーンとからなり同級着ゾーンを海流の上流側
に同沈降分離ノ゛−ンを下流側に配した吸着装置。The present invention solves the drawbacks of the above-mentioned conventional technology and the above-mentioned prior art, allows the uranium adsorbent to come into contact with seawater efficiently and uniformly, makes it possible to extract uranium from seawater efficiently, and is small in size. This system was proposed for the purpose of providing a uranium extraction equipment with low construction cost, and it is equipped with an adsorption zone where particulate adsorbent and seawater are mixed, and multiple adsorbent deposition beds arranged vertically. An adsorption device consisting of an adsorbent sedimentation separation zone, with a co-classification zone placed on the upstream side of the ocean current and the same sedimentation separation zone placed on the downstream side.
前記吸着ゾーンに粒子状吸着剤を微細する手段。Means for micronizing particulate adsorbent in the adsorption zone.
前記沈降分離ゾーンから粒子状吸着剤を回収する手段、

徴とする海水ウラン採取装置を提供する。means for recovering particulate adsorbent from the sedimentation separation zone;
111. To provide a seawater uranium extraction device characterized by comprising an air tank with buoyancy fixed to an adsorption device, and a mooring device for mooring the adsorption device to the sea surface.
本発明装置においては、前記吸着ノーンにおいて海水中

沈険分駈ゾーンに設けられた複数個の前記吸着剤沈積床
上に沈積する。その後同沈積床上に沈積した吸着剤ｋ
ｒｉｉｌ記回収手段によって回収する。In the apparatus of the present invention, particulate adsorbent is dispersed in the seawater in the adsorption noon to adsorb uranium and N, and then the adsorbent is carried away by ocean currents and transferred to the sedimentation separation zone.
The adsorbent is deposited on a plurality of beds provided in the deposition zone. After that, the adsorbent k deposited on the same sedimentation bed
It is collected by a recovery means.
本発明装置によれば２粒子状吸着剤を前記吸着ゾーンで
海水中に散布するようにしているため、海水との接触効
率が良く、かつ均一に接触でき、そのためウラン採取効
率が良い。According to the apparatus of the present invention, since the two-particulate adsorbent is dispersed into the seawater in the adsorption zone, the contact efficiency with the seawater is high and uniform contact is possible, and therefore the uranium extraction efficiency is high.
さらに前記沈降分離シーツで吸着剤を沈積床上に沈積さ
せた後回収するようにしているので。Furthermore, the adsorbent is collected after being deposited on the sedimentation bed using the sedimentation separation sheet.
吸着剤を効率よく短時間で海水と分離し回収できる。The adsorbent can be efficiently separated from seawater and recovered in a short time.
まだ粒子状吸着剤を吸着ゾーンで海水中に散布し海水と
接触きせるようにしているので、格子状吸着剤に比べて
海水通過時の抵抗が小さく。Since the particulate adsorbent is still dispersed into the seawater in the adsorption zone so that it comes into contact with the seawater, the resistance when seawater passes through it is lower than with grid-like adsorbents.
従って吸着層の通水断面積を大きくする必要がないので
、装置の大形化を招かず、さらに吸着装置に浮力をもつ
空気槽を固着せしめ吸着装置自体で海面に浮遊できるよ
うにしているだめ。Therefore, there is no need to increase the water flow cross-sectional area of the adsorption layer, so the device does not become larger, and an air tank with buoyancy is fixed to the adsorption device so that the adsorption device itself can float on the sea surface. .
吸着装置の海面保持に要する力を軒減でき、−網装置を
小形化できる。The force required to hold the adsorption device at sea level can be reduced, and the net device can be made smaller.
