GAS DISSOLVING EQUIPMENT AND OXYGEN DISSOLVING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide gas dissolving equipment and oxygen dissolving system capable of additionally increasing the amount of dissolved gas (amount of dissolved oxygen) in the liquid (sample water) in a dissolving tank. SOLUTION: A supply pipe 4 for supplying the sample water and gaseous oxygen to the dissolving tank 3 is disposed between a pump 2 and dissolving tank 3 constituting the oxygen dissolving system 1 and a nozzle 5 for irradiating the sample water and the gaseous oxygen is disposed at the front end of the supply pipe 4. The nozzle 5 is set in the central part atop the dissolving tank 3 in such a manner that its diffuser faces perpendicularly downward. Stagnating members 6 which are a plurality of disks are disposed apart prescribed spacings from each other in the dissolving tank 3 and holes 7 having prescribed sizes are respectively formed in their central parts. A collision member 8 which is a disk not provided with the hole is disposed below the disk of the lowermost part provided with the holes 7.
