Title:
GAS DISSOLVING APPARATUS
Document Type and Number:
Japanese Patent JP2010051846
Kind Code:
A
Abstract:

To provide a gas dissolving apparatus preventing generation of bubbles and providing stable gas-dissolved solution of high concentration in a batch type.

The gas dissolving apparatus includes a pressurizing dissolving part 3 formed of a sealed tank for storing liquid 16; a gas injection part 2 injecting gas 19 into the pressurizing dissolving part 3; and a pressure reducing part 4 reducing the pressure of the gas-dissolved solution 10 dissolved with the gas 19 by the pressurizing dissolving part 3 from an inflow side toward an outflow side to the atmospheric pressure sequentially. The pressurizing dissolving part 3 dissolves the gas 19 into the liquid 16 by pressurizing by batch type gas injection, and quantitatively sends the gas-dissolved liquid 10 from the pressurizing dissolving part 3 to the pressure reducing part 4.
