Verfahren und Vorrichtung zum Einspritzen flüssiger Stoffe in ein Flotationsbecken.

摘要

Method for injecting fluids into a flotation tank where the flotation is produced by decompression of a liquid saturated with a gas under pressure into a liquid containing suspended particles which must be separated from the liquid by flotation, this process being characterised in that it consists, when the pressurised liquid has undergone a first decompression, in ensuring a second decompression by means of a member which at the same time ensures the mixing of the microbubbles thus formed with the liquid to be treated, under optimum conditions, and in arranging the said member in an enclosure placed in the tank where the flotation takes place, to which the liquid to be treated is brought, shaped so as to create, successively from the bottom upwards, a zone for channelling the liquid to be treated, a zone for mixing this liquid with the microbubbles and, finally, a zone for deceleration of the liquid stream leaving the enclosure.
