Abstract
A device according to the invention for dispersing a gas into a liquid comprising a liquid volume and a nozzle which is immersed in the liquid volume below a liquid level. The nozzle has a conical annular gap at the tip of which a nozzle opening is provided, and a liquid feed line opening tangentially into the conical annular gap. A gas feed line 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.
Claims16
A device for dispersing a gas into a liquid having a liquid volume, the device comprising:
- a nozzle for feeding a liquid into the liquid volume, which nozzle has a conical annular gap that is disposed between a conical internal face of a nozzle casing and a guide cone and on a tip of said conical annular gap at a nozzle opening opens out into the liquid volume below a liquid level;
- a liquid infeed which opens tangentially into the conical annular gap;
- and
- at least one gas infeed for a gas to be dispersed into the liquid volume, wherein the at least one gas infeed in the liquid volume opens out laterally to the nozzle opening and at an angle to a central axis of the conical annular gap.
A method for dispersing a gas into a liquid, in which method:
- a) a liquid is fed to a nozzle which has a conical annular gap, wherein the liquid is supplied into the annular gap by way of a liquid infeed that opens tangentially into the annular gap;
- b) the liquid in the annular gap is forced into a path constricted in the shape of a spiral, and at a nozzle opening disposed on a tip of the conical annular gap, below a liquid level of a liquid volume, is ejected in the form of a swirled liquid jet into the liquid volume;
- c) a gas to be dispersed is introduced into the liquid infeed and/or into the nozzle and/or into the swirled liquid jet ahead of the nozzle opening;
- and
- d) wherein the gas is ionized prior to being fed to the liquid.
A device for dispersing a gas into a liquid having a liquid volume, the device comprising:
- a nozzle for feeding a liquid into the liquid volume, which nozzle has a conical annular gap that is disposed between a conical internal face of a nozzle casing and a guide cone and on a tip of said conical annular gap at a nozzle opening opens out into the liquid volume below a liquid level;
- a liquid infeed which opens tangentially into the conical annular gap;
- and
- at least one gas infeed for a gas to be dispersed into the liquid volume, which gas infeed opens out into the liquid infeed and/or the annular gap and/or in the region of the nozzle opening;
- wherein the guide cone of the nozzle is axially adjustable in relation to the conical internal face of the nozzle casing.
