Description

図示例において、滴下針２８は、管（主管１４および枝管１６）の滴下口２６に対向する頂部に固定（螺合）されるボルト３０の下端（液導入部２４では、ストレーナの下端）に固定され、此処から垂下するようにして滴下口２６を通過、突出するが、本発明において、滴下針２８の取り付け方法は、これに限定はされず、例えば、管の内壁頂部に溶接等で直接滴下針２８を固定する方法等、公知の方法が各種利用可能である。 In the illustrated example, the dropping needle 28 is attached to the lower end of the bolt 30 fixed (screwed) to the top of the pipe (main pipe 14 and branch pipe 16) facing the dropping port 26 (in the liquid introduction portion 24, the lower end of the strainer). It is fixed and passes through and protrudes from the dropping port 26 so as to hang down from here, but in the present invention, the method of attaching the dropping needle 28 is not limited to this, and for example, it is directly attached to the top of the inner wall of the pipe by welding or the like. Various known methods such as a method of fixing the dropping needle 28 can be used.

このような液分散器１０の液導入部２４に、定量ポンプでエタノール（１０℃での粘度が約１．３ｃｐ）を３０Ｌ（リットル）／ｈｒおよび６０Ｌ／ｈｒ供給して、充填塔内にエタノールを分散供給した。各例における流量は、３０Ｌ／ｈｒの場合が、
（０．０３［ｍ³／ｈｒ］）／（０．２８３［ｍ²］）
≒０．１１［ｍ³／（ｍ²・ｈｒ）］
６０Ｌ／ｈｒの場合が、
（０．０６［ｍ³／ｈｒ］）／（０．２８３［ｍ²］）
≒０．２１［ｍ³／（ｍ²・ｈｒ）］
である。 Ethanol (viscosity at 10 ° C. of about 1.3 cp) is supplied at 30 L (liter) / hr and 60 L / hr to the liquid introduction section 24 of the liquid disperser 10 by a metering pump, and ethanol is supplied into the filling column. Was distributed and supplied. When the flow rate in each example is 30 L / hr,
(0.03 [m ^{3 /} hr]) / ^{(0.283 [m 2])}
≒ 0.11 [m ³ / (m ² · hr)]
In the case of 60L / hr,
(0.06 [m ^{3 /} hr]) / ^{(0.283 [m 2])}
≒ 0.21 [m ³ / (m ² · hr)]
Is.
