上記トリチウムは排出ガス中の水分に含まれてい

中の水分を抽出することが必要となつてくる。 In nuclear reactor facilities such as nuclear reactor power plants, it is extremely important for safety management to measure the amount of tritium contained in the exhaust gas.
The above tritium is contained in the moisture in the exhaust gas, and in order to measure the amount of tritium, it is necessary to extract the moisture in the exhaust gas.

続的に回収するような場合、露点条件によつて
は、（たとえば露点条件が０℃以下の場合）、抽出
効率が、きわめて低いという問題があつた。 Conventionally, in order to extract moisture from exhaust gas, the sampled exhaust gas was used in a pump to increase the pressure, the relative humidity was increased, and a dehumidifier was used to extract the moisture. However, since a dehumidifier is used, the temperature cannot be lowered to below 0°C, which naturally limits the dew point conditions of the exhaust gas to be sampled. Therefore, when water in exhaust gas is continuously recovered, there is a problem that the extraction efficiency is extremely low depending on the dew point conditions (for example, when the dew point condition is 0° C. or lower).
この考案は上記の点に鑑みてなされたもので、
構成簡単で可動部分がなく、信頼性に優れ効率良

言うまでもない。 In the above embodiment, a plate-shaped ice adherent was used as the ice adherent provided in the tube body 11, but this is not limited to a plate-like ice adherent; for example, as shown in FIG. A large number of spherical ice deposits 19, 19, . . . may be filled. In this case, it is preferable to use a large ball near the exhaust gas inlet 11a and a small ball behind it from the viewpoint of the flowability of the exhaust gas (dry gas), as described above. In this way, the above-mentioned icing body may have a structure that allows the gas flow path to be as long as possible and does not impede the flow of water, and various other types may be used. It goes without saying that the device of this invention can be used not only in the case of detecting the amount of tritium in the exhaust gas of nuclear reactor equipment as in the above embodiment, but also in a wide range of fields.
