ていく。1: Dehumidification tower (dehumidifies air) 2: Blower 3: Water spray header 4: Cooler (using cold water or direct expansion of refrigerant) 5: Pump (for high concentration absorption liquid) 6: Absorption liquid (low concentration) 7: Return duct 8: Supply duct 9: Filling material A: Humid air (retan air) B: Dry air (supply air) C: Outside air D: Exhaust 11: Regeneration tower (regenerates absorption liquid) 12: Blower 13: Watering header 14: Heating 15: Pump (for low concentration absorption liquid) 16: Absorption liquid (high concentration) 17: Outside air duct 18: Exhaust duct 19: Filling material In Figure 5, return duct 7 from the drying room etc.
The humid air that returns after passing through enters the dehumidification tower 1,
Here, moisture is absorbed by the absorbent liquid (calcium chloride, triethylene glycol, etc.) flowing on the surface of the filler 9 and dried, and by the action of the blower 2,
It passes through the supply duct 8 and exits as dry air B.
一方、空気から水分を吸収し、低濃度になつた

を通つて排気Ｄとして屋外に放出される。 On the other hand, the absorption liquid 6, which has absorbed moisture from the air and has become low in concentration, is sent to the regeneration tower 11 by the pump 15, and after being heated to a predetermined temperature by the heater 14,
Water is poured into the filling material 19 by the water spray header 13 . The outside air C sucked in from the outside air duct 17 by the action of the blower 12 becomes highly humid due to moisture evaporated from the absorption liquid flowing on the surface of the filler 19, and is drawn into the exhaust duct 18 by the action of the blower 12.
is discharged outdoors as exhaust D.
水分を蒸発して高濃度になつた吸収液１６は、
ポンプ５の作用により冷却器４で所定温度まで冷
却されたあと、除湿塔１の散水ヘツダー３に送ら
れて、充てん材９の上に散水される。 The absorption liquid 16 that has become highly concentrated by evaporating water is
After being cooled down to a predetermined temperature in the cooler 4 by the action of the pump 5, the water is sent to the water sprinkler header 3 of the dehumidification tower 1 and sprinkled on the filler 9.
冷却器４で冷却された低温の吸収液が水分を吸
収し、加熱器１４で加熱された高温の吸収液が水
分を蒸発するのは、吸収液の濃度と蒸気圧の関係
に帰因する。吸収液の一例として、塩化リチウム

対湿度約15％の空気と平衡する。言い換れば、15
％以上の相対湿度の空気は、充分な時間の後に
は、15％まで乾燥される。 The reason why the low-temperature absorption liquid cooled by the cooler 4 absorbs moisture and the high-temperature absorption liquid heated by the heater 14 evaporates moisture is due to the relationship between the concentration of the absorption liquid and its vapor pressure. As an example of an absorption liquid, when using a lithium chloride solution, when the absorption liquid temperature is 20℃, the concentration
A 40% absorbing liquid has a water vapor partial pressure of 2.7 mm Hg and is in equilibrium with air at a relative humidity of approximately 15%. In other words, 15
% relative humidity or more will, after sufficient time, be dried to 15%.
一方、同じく40％の濃度で100℃の吸収液の水
蒸気分圧は、200mmHgであり、これを25℃80％
（水蒸気分圧19mmHg）の空気と接触させれば、吸
収液から空気に水分が移動し、吸収液は濃縮され
る。 On the other hand, the water vapor partial pressure of the absorbing liquid at 100℃ with the same concentration of 40% is 200mmHg, which is 80% at 25℃.
When brought into contact with air at a water vapor partial pressure of 19 mmHg, moisture moves from the absorption liquid to the air, and the absorption liquid becomes concentrated.
このような水分吸収液を用いた気液接触式除湿
機は、低露点の乾燥空気ができる、濃度の調節に
より比較的容易に相対湿度をコントロールでき
る、などの利点をもつ反面、外気の導入が不可欠
であり、除湿装置が大形となる等の欠点をもつ。 Gas-liquid contact dehumidifiers that use such moisture-absorbing liquids have advantages such as producing dry air with a low dew point and relatively easy control of relative humidity by adjusting the concentration, but they do not require the introduction of outside air. However, it has drawbacks such as the large size of the dehumidifier.

そこで、この点を改良するのが、本発明の目的で
ある。(Problems to be Solved by the Invention) As described above, in the conventional dehumidification device, outside air C is required in order to regenerate the absorption liquid diluted by dehumidification, and the outside air duct 17 and the exhaust duct 18 are installed. Alternatively, the regeneration tower 11 itself needs to be installed outdoors, which increases the size of the equipment and increases the equipment cost.
Therefore, it is an object of the present invention to improve this point.

ため、省エネルギーとなる。(Effects of the Invention) In the present invention, in a gas-liquid contact dehumidifier or a condensable gas removal device that uses a water absorption liquid, the principle of a steam regeneration condensation heat pump is utilized for regenerating (concentrating) the absorption liquid. This eliminates the need to introduce outside air into the regeneration section, eliminating the need for outside air ducts and exhaust ducts found in conventional devices, making it possible to house the entire dehumidifier in an integrated cabinet and install it indoors. Furthermore, since the heat source of the heating coil is not required, energy is saved.
