Abstract (en)

[origin: WO2022218636A1] A device according to the invention for dispersing a gas into a liquid comprises a liquid volume (2, 21, 43) and a nozzle (3, 22, 41) which is immersed in the liquid volume below a liquid level (42). The nozzle has a conical annular gap (7, 26), at the tip of which a nozzle opening (9, 28) is provided, and a liquid feed line (5, 24) opening tangentially into the conical annular gap. A gas feed line (10, 29, 49) for a gas to be dispersed into the liquid volume opens into the liquid feed line, into the annular gap or in the region of the nozzle opening. The nozzle causes a strong swirling movement in the liquid fed into the liquid volume, which allows good dispersion of the gas that has been introduced via the gas feed line.
