| 9. A gas-liquid dissolving apparatus comprising:
a supplying unit that supplies a gas-liquid multi-phase fluid in which a liquid and a gas are mixed up;
a gas-liquid dissolving chamber that receives a flow of the gas-liquid multi-phase fluid in an upper portion and that has
a relief hole formed in a lower portion for releasing fluid;
a nozzle that penetrates the gas-liquid dissolving chamber and that ejects the gas-liquid multi-phase fluid supplied by the
supplying unit upward toward the upper portion of the gas-liquid dissolving chamber;
a gas-liquid separating chamber that is provided outside the gas-liquid dissolving chamber while communicating with the gas-liquid
dissolving chamber through the relief hole, that stores the gas-liquid multi-phase fluid from the relief hole, and that separates
the liquid from the gas; and
a takeout port from which the liquid separated in the gas-liquid separating chamber is taken out, wherein
a dissolved gas component concentration of the liquid is increased by agitation caused by a force of ejection from the nozzle
and a reflux from the upper portion of the gas-liquid dissolving chamber.
