本発明は、不純物析出層が精製装置を閉塞しに（い液体
金属（例えばＮａ、になど、以下ＬＭと略す）の精製装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for purifying liquid metals (such as Na, etc., hereinafter abbreviated as LM) in which impurity deposits clog the apparatus.
従来、ＬＭは高速増殖炉の冷却用などで使われる場合に

るものを更に純化しているものである。したがって。Conventionally, when LM is used for cooling fast breeder reactors, etc., it has a high purity (for example, the oxygen concentration is about 1 to 5 wpp+n).
), it is purified by cold trap purification, that is, by introducing LM into low Iu volume J4), and trapping impurities that cause saturated solubility by precipitation on the surface of a wire mesh packing. During normal operation, a part of the LM in the main cooling system is guided to the purification system), but this is used at high purity and
It is a further purification of what is already known. therefore.

２のワイヤ表向に不純物が４１ｒ出捕獲される。The amount of impurities captured per hour by a cold trap is small; in other words, in order to further refine high-purity products, extremely high impurity capture properties are required. Cold trap device? A common example since iL is shown in FIG. As shown in FIG. 1, there is a cooling packing 2 such as a laminated wire mesh in the straight body of the purification container body 1, and a cooling jacket 11 is provided around the outer circumference of the cooling packing 2. As shown in FIG. LM flows in from the LM inlet nozzle 4, reverses from the downcomer pipe 5 at the lower plenum 6, flows through the cooling packing 2, passes through the upper plenum 7, and flows out from the LM outlet nozzle 8. Cooling air flows into the annular space from the cooling gas inlet pipe 9 of the cooling jacket 11 and flows out from the cooling gas outlet pipe IO. The purification container main body and cooling filling are air-cooled to 1 tic 1 lot (approx. 1+ o in case of Na).
t: 1ilIt! ), impurities 41r are emitted and captured on the surface of the wire of the cooling filler 2.

合にはローカルに不純物塊が仔在することもありうる。At the time of the fast reactor's steam reactor's collapse, a considerable amount of wood was destroyed. Since the force is exerted during the first phase, the net power of LM decreases all at once. In terms of oxygen concentration, the secondary cooling system L kj 31' average is several tens to hundreds of W p

ある必要はない。Here, the LM inflow means and the LM outflow means may be any means that communicates with the LM system and allows LM to flow in and out of the purification vessel body, including pipes (regardless of cross-sectional shape) and simple inflow means. It may also be an outlet or an outlet. Also,
The cooling system for impurities (11) refers to a means for transporting the heat of crystallization at the time of impurity precipitation out of the purification vessel.1 For example, cooling pipes and cooling jackets in which refrigerant is circulated, and parts of them that come into contact with the cooling pipes or cooling jackets. Metal wires or wire mesh may also be used. Preferably, cooling pipes or cooling jackets that circulate refrigerant have a large cooling capacity and are suitable. Multiple independent cooling systems are defined as systems in which the capacity of the cooling systems can be increased or decreased independently of each other. Refers to a cooling system of two or more units, and it is not necessarily necessary to use a separate refrigerant supply means. For example, if each cooling system is equipped with a valve that can increase or decrease the flow of refrigerant,
The refrigerant supply means may be an 11-tea-9 type, but it is preferable that the refrigerant supply means be 11-tea-9 type. Providing a plurality of independent cooling systems with different distances from a specific flow path means that it is sufficient to ensure at least one flow path with different distances from each cooling system when viewed from the plurality of cooling systems. When refining a large amount of impurities due to a heat exchanger tube breakage accident, etc., by operating the cooling system closest to the flow path and sequentially adding the cooling systems closest to the flow path, the precipitation of impurities can be reduced from the flow path. This occurs from the farthest point, making it less likely that the flow path will be blocked. Note that the specific flow path does not necessarily have to be one.

Furthermore, by wrapping a laminated wire mesh or the like around the coiled cooling pipe 16 so as to contact only each cooling system, or by reducing the coil pitch, the precipitation area will be expanded and the refining capacity will be improved. The same effect can be obtained even if the diameter of the cooling pipe used in each cooling system is made smaller to increase the number of cooling systems.

得られる。In addition, the first embodiment 13'll and the fourth embodiment are suitable for a long-shaped refining container, and the second embodiment 4 and the third embodiment 11 are suitable for a short-body type. In addition, in the first to third embodiments, a plurality of systems of cooling pipes for the interior of the refining vessel were shown, and in the fourth embodiment, a plurality of systems of cooling jackets were shown separately. The object of the present invention can be achieved more effectively by combining the above. Further, in each of the embodiments, an example has been described in which the cooling pipe artificial valve is used in a closed or fully open state, but in some cases, it is better to use a -ra+ valve in a partially open state to achieve an appropriate Δ inside the plenum. There is also a favorable time to maintain the 1 degree distribution, so each cooling valve has a flow frL:J
, it is more preferable to use one that allows +1 clauses. In each example, the explanation was carried out by specifying the LM flow nozzle and the LM outflow nozzle and keeping the direction of the flow constant, but by replacing the 11M inflow nozzle and the Of course, the same effect can be obtained even if the flow is reversed.

Even when refining a large amount of impurities due to accidents caused by damage to heat transfer, the impurity precipitation layer will be small enough to prevent the impurities from clogging the LM flow path, so the refining capacity will be reduced more than necessary. Since there is no need to remove the
This makes it possible to effectively utilize the top of the container and create a purification device with no blockages.
