Abstract

A gas solution production apparatus includes a gas dissolving unit that dissolves gas of a second raw material into a liquid of a first raw material to generate a mixture liquid, and a gas-liquid separation unit that subjects the liquid mixture generated by the gas dissolving unit to gas-liquid separation into a gas solution that is supplied to a use point and an exhaust gas that is discharged from an exhaust port. The gas-liquid separation unit includes a capacity variable section that changes a capacity of an internal space of the gas-liquid separation unit.

First claim

What is claimed is:

1. A gas solution production apparatus, comprising:
a gas dissolving unit that dissolves gas of a second raw material into a liquid of a first raw material to generate a liquid mixture; and
a gas-liquid separation unit that separates the liquid mixture generated by the gas dissolving unit into a gas solution that is supplied to a use point and an exhaust gas that is discharged from an exhaust port,
wherein the gas-liquid separation unit includes a capacity variable section that changes a capacity of an internal space of the gas-liquid separation unit for receipt of the liquid mixture into the internal space.

2. The gas solution production apparatus according to claim 1 ,
wherein the capacity variable section is a capacity variable body that is housed in the internal space of the gas-liquid separation unit, and
by supplying gas to an inside of the capacity variable body, a volume of the capacity variable body increases, and the capacity of the internal space of the gas-liquid separation unit decreases, whereas by discharging gas from the inside of the capacity variable body, the volume of the capacity variable body decreases, and the capacity of the internal space of the gas-liquid separation unit increases.

3. The gas solution production apparatus according to claim 1 ,
wherein the capacity variable section is an expansion/contraction variable structure that is integrated with a body of the gas-liquid separation unit, and
by contracting the expansion/contraction variable structure, the capacity of the internal space of the gas-liquid separation unit decreases, whereas by expanding the expansion/contraction variable structure, the capacity of the internal space of the gas-liquid separation unit increases.

4. The gas solution production apparatus according to claim 1 ,
wherein the gas-liquid separation unit includes a load measurement section that measures a load of the gas-liquid separation unit.

5. The gas solution production apparatus according to claim 4 ,
wherein the gas-liquid separation unit includes a liquid level calculation section that calculates a liquid level of the gas solution inside the gas-liquid separation unit, from the load of the gas-liquid separation unit, which is measured by the load measurement section.

6. The gas solution production apparatus according to claim 2 ,
wherein the gas-liquid separation unit includes a load measurement section that measures a load of the gas-liquid separation unit.

7. The gas solution production apparatus according to claim 3 ,
wherein the gas-liquid separation unit includes a load measurement section that measures a load of the gas-liquid separation unit.

8. The gas solution production apparatus according to claim 1 , wherein the gas dissolving unit is configured to dissolve any one or more of gaseous ozone, hydrogen, nitrogen, carbon dioxide, oxygen, argon and xenon into liquid pure water or liquid sulfuric acid.

9. The gas solution production apparatus according to claim 1 , wherein the gas solution production apparatus is configured to control the capacity of the internal space to a predefined capacity by a respective measured action of or to the capacity variable section.

10. A gas solution production apparatus, comprising:
a gas-liquid separation unit including a body defining a chamber configured to receive a liquid material being a mixture of gaseous and liquid components, wherein the gas-liquid separation unit is configured to separate the received liquid material in the chamber into at least a pair of resultant gaseous materials for being separately output from the chamber; and
a capacity variable section disposed at the gas-liquid separation unit and configured to vary a maximum volume of the liquid material stored within the chamber via a respective measured action of or to the capacity variable section.

11. The gas solution production apparatus of claim 10 , wherein the gas solution production apparatus is configured to determine the volume of the liquid material within the chamber according to a load of the liquid material in the chamber.

12. The gas solution production apparatus of claim 10 , further comprising a gas dissolving unit configured to dissolve a first gaseous material into a first liquid material resulting in the liquid material that is received into the chamber.

13. The gas solution production apparatus of claim 10 , wherein a maximum volume of the chamber is fixed.

14. The gas solution production apparatus of claim 10 , wherein a maximum total volume of the chamber is variable via an action of the capacity variable section.
