Abstract:
1. A liquid-to-gas contact device comprising: a liquid-to-gas contact medium; a gas inlet; a gas outlet; a liquid supply port; a tank for liquid; and a container for the liquid-to-gas contact medium; wherein: the liquid-to-gas contact medium is constituted of a honeycomb structural body, the honeycomb structural body including a plurality of gas flow passages in the form of a plurality of through channels defined by a plurality of partition walls and extending through the honeycomb structural body in an axial direction, and a plurality of liquid flow passages formed to extend through the honeycomb structural body from an outer peripheral surface side of the honeycomb structural body; the tank for the liquid is formed as a part of the container, and is constituted in such a manner that the outer peripheral surface of the honeycomb structural body forms an inner peripheral surface of the tank for the liquid when the liquid-to-gas contact medium is disposed in the container; and the plurality of partition walls comprise unidirectionally permeable structures that prevent gas in the gas flow passages from entering into the liquid flow passages, but allow liquid in the liquid flow passages to permeate into the gas flow passages by capillary action.
