Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は定湿気体発生装置の飽和槽に関する。The present invention relates to a saturated tank of a constant humidity body generator.
感湿素子の較正、各種材料・部品などの湿度特性を試験
するのに、正確に湿度の判った気体を発生する装置を利

った水蒸気圧を示すということを利用している。In order to calibrate the humidity sensitive element and test the humidity characteristics of various materials and parts, a device that generates a gas whose humidity is accurately known is often used. There is an apparatus using such a diversion method, two-temperature method, two-point pressure method, etc. (JIS humidity measurement method, Z8806). Both devices use a saturation tank that generates a gas with a constant water vapor pressure. This takes advantage of the fact that water at a certain temperature exhibits a fixed water vapor pressure.

槽は同一のあるいは別々の恒温槽６中に収めてある。FIG. 2 shows an example of a conventional constant humidity body generator. The gas that has passed through the gas inlet 2 provided in the lower portion of the cylindrical saturated tank body 1 containing an appropriate amount of water passes through the water 4 as fine gas from many small holes of the filter 3, It becomes saturated gas and reaches the upper space 5 of the saturated tank body 1. The diversion method mixes a saturated gas from a saturated tank and a dry gas at an arbitrary ratio and introduces the mixed gas into a test tank, and its relative humidity is almost equal to the mixing ratio. The two-temperature method guides the air flow from the saturation tank to a test tank that is maintained at a temperature equal to or higher than the temperature of the saturation tank, and the ratio of the saturated vapor pressure at each temperature of the saturation tank and the test tank is relative to the relative humidity in the test equipment. Become. In the two-point pressure method, the gas from the saturation tank is depressurized and a gas having a relative humidity equal to the reciprocal of the depressurization ratio is generated. Since the temperature of the saturation tank is constant and the temperature distribution is required to be uniform in all the devices, the saturation tank and the test tank are usually contained in the same or different constant temperature tanks 6.
一般に恒温槽は熱容量が大きいので、温度を急速に変え
ることは難しい。また、大量の気体を必要とする場合、
飽和槽したがって恒温槽も大きなものになるので、経済
性の面でも問題となることが多い。Generally, since the constant temperature bath has a large heat capacity, it is difficult to change the temperature rapidly. Also, if you need a large amount of gas,
Since the saturation tank and therefore the constant temperature tank also become large, there are often problems in terms of economy.
先に述べたように、飽和槽はあるきまった水蒸気の気体
を発生させるもので、基本的には飽和槽の水温が一定に
なればよい。必ずしも飽和槽全体を一定の温度に保つ必
要はない。As described above, the saturation tank generates a certain vapor gas of steam, and basically the water temperature in the saturation tank should be constant. It is not always necessary to keep the entire saturation tank at a constant temperature.

点を解消している。In the present invention, the saturated tank of the constant humidity body generator, a saturated tank body having a gas inlet in the lower part, the inside of which is filled with water leaving a space part in the upper part, and the saturated tank from the space part. The above-mentioned problem is solved by configuring the gas outlet pipe through the water to reach the saturated gas outlet.

While passing through the gas outlet pipe according to the present invention, saturated steam corresponding to the water temperature of the saturation tank is obtained. Is obtained.

の優劣も判じ難いことになる。Hereinafter, the present invention will be described in detail according to examples. FIG. 1 is a schematic view of an embodiment of the present invention. The gas that has passed through the gas inlet 2 provided at the bottom of the saturation tank body 1 becomes fine bubbles from many small holes of the filter 3 and passes through the water 4 to become a saturated gas, which is the upper space of the saturation tank body 1. Up to 5.
The temperature of the water 4 in the saturation tank is appropriately set to a desired temperature by the heating (cooling) coil 7. In the case of the present invention, the saturation tank body 1 is not placed in a constant temperature tank, so it must be considered that a temperature difference is always generated between the water 4 and the upper space 5 due to the influence of the temperature outside the saturation tank. When the temperature of the upper space 5 or the wall of the upper space 5 is lower than the water temperature, the water vapor in the saturated gas partially condenses therein, and the gas is dehumidified.
When the temperature of the upper space 5 or the wall of the upper space 5 is high, the water droplets brought into the upper part of the saturation tank along with the bubbles are evaporated, and the gas is humidified. The upper space 5 may be adiabatically kept warm (cooled) so that it has the same temperature as the water temperature in the saturation tank, but highly technically high temperature control must be performed. Therefore, it is difficult to understand the superiority or inferiority of the conventional system in which the saturation bath is placed in the constant temperature bath.

気体出口９から得られる。気体導出管８で凝縮した水は
水封装置10を通して外部に排出する。In the present invention, the generated gas is supplied from the saturated tank upper space 5 to the test tank through the saturated gas outlet 9 after passing through the underwater gas outlet pipe 8. Therefore, the temperature of the upper space 5 is higher than that of the water 4 (fine temperature control is not required)
Then, as described above, the gas is humidified in the upper space 5, but when passing through the gas outlet pipe 8, in the portion below the water surface (equal to the temperature of the water 4), Water vapor condenses. If the length and surface area of the conduit where condensation occurs are appropriate, a gas having a saturated vapor pressure corresponding to the water temperature of the saturated tank is obtained from the saturated gas outlet 9. The water condensed in the gas outlet pipe 8 is discharged to the outside through the water sealing device 10.
気体導出管８として、水は通さないが水蒸気は透過する
ような疏水性の多孔質管を用いてもよい。この場合は上
部空間５の温度は水４より低くてもかまわない。上部空
間５で減湿されても、水４の温度の水蒸気圧まで気体導
出管８の多孔質壁を透して水蒸気が気体中に補給される
からである。As the gas outlet pipe 8, a hydrophobic porous pipe that does not allow water to pass but allows water vapor to pass may be used. In this case, the temperature of the upper space 5 may be lower than that of the water 4. This is because even if the upper space 5 is dehumidified, the water vapor is replenished into the gas through the porous wall of the gas outlet pipe 8 up to the water vapor pressure of the temperature of the water 4.
このように、恒温槽を使用しなくても、飽和槽の水温の
みで規定される水蒸気圧をもつ気体を発生することがで
きるので、装置をコンパクトにすることができ、経済的
にも有利である。また、温度を急速に変えることも可能
となる。As described above, since a gas having a water vapor pressure regulated only by the water temperature of the saturation tank can be generated without using a constant temperature tank, the device can be made compact and economically advantageous. is there. Also, it is possible to change the temperature rapidly.
