Abstract

See full text

A process and device for mixing and dissolving gas (G) in liquid (F), this latter being introduced under pressure through a nozzle plate (12) into a reaction space (1), whence a mixture of gas (G) and solution (L) flow out through outlets (10) laterally at the bottom into a solution tank (2) and the gas (G) recirculates through inlets (11) at the top near the nozzle plate (12). The solution tank (2) is filled to a level (N1) between the in- and outlets (11, 10) at a medium pressure; the dissolved body of gas (G) is delivered subsequently via a gas flow regulator (5) and the solution (L) is drawn off from the solution tank (2) at a low pressure level via a control valve (24) as a supersaturated solution (UL). An embodiment of the nozzle plate (12) is disclosed with injector nozzles at the edge and mixing nozzles on the inside.
