<P>PROBLEM TO BE SOLVED: To provide a compact gas dissolving apparatus that can generate liquid having sufficiently high gas dissolution amount corresponding to requested efficacy even if an oxygen enrichment unit is not provided. <P>SOLUTION: A dissolution tank 2 for generating the liquid 5 where gas is dissolved includes: an inflow part 12 that guides a gas-liquid mixed fluid containing dissolved gas and liquid into the dissolution tank; an outflow part 13 that draws the generated liquid from the dissolution tank; an exhaust part 15 that discharges the gas accumulated in the dissolution tank outside the dissolution tank; and a gas circulation path 14 that returns the gas accumulated in an upper dissolution tank into the inflow part and circulates the gas. The gas-liquid mixed fluid flowed from the inflow part is a mixture of water and air. An exhaust amount of a gas emitted by the exhaust part is set to be equivalent to or above 20% of an intake amount of a gas guided into the dissolution tank as an gas-liquid mixed fluid through the inflow part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
