CARBON DIOXIDE GAS DISSOLUTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a carbon dioxide gas dissolution device capable of extremely efficiently dissolving various carbon dioxide gases, without using a complicated gas-liquid mixing mechanism.SOLUTION: A carbon dioxide gas dissolution device comprises a water treatment member 1 having a member body 6 for forming a water flow passage in a penetration form and forming an orifice part 2c smaller in the flow cross-sectional area than an inflow port in a midway position of the flow passage and a collision part of projecting from an inner peripheral surface of the flow passage in the form of partitioning an axial cross section of the flow passage into two or more of segment areas 2e by the orifice part 2c, having a plurality of turns of orifice ribs in the circumferential direction on an outer peripheral surface and further reducing the flow passage cross-sectional area of the orifice part 2c and a carbon dioxide gas supply part 12 for making carbon dioxide gas flow in from a carbon dioxide gas supply source positioned in an external part of the member body in the water flow passage of the member body 6. A flow of water supplied to the inflow end of the member body 6 of the water treatment member 1, is passed by increasing a speed while distributing to the respective segment areas 2e after colliding with the collision part 3, and carbon dioxide gas is dissolved by mixedly crushing by rolling in a turbulent flow area formed just downstream of the collision part.
