Device for dispersion of gas in a liquid phase
First Claim
1. A device for the dispersion of a gaseous phase in a liquid phase, comprising a venturi ejector, oriented substantially vertically and arranged for downward flow of the liquid phase and immersion in the liquid phase, the venturi ejector comprising:
- a convergent nozzle (1) for introduction of the liquid phase, a neck (2) connected to the convergent nozzle at a point of the same internal diameter as the convergent nozzle at the point of connection, the neck having means for the admission of the gas and a divergent nozzle (3) connected to the neck at a point of the same internal diameter as the neck at the point of connection wherein the divergent nozzle (3) is connected to a perforated cylindrical piece (4) of a diameter equal to the diameter of the exit of the divergent nozzle, having perforations of a length substantially equal to the diameter, the device is extended by an extension piece (5) of a diameter at least equal to the diameter of the perforated cylindrical piece, in communication with the perforated cylindrical piece.

Abstract
A device for dispersing a gaseous phase in a liquid phase comprises at least one Venturi ejector with a vertical or inclined axis, composed of a mixer head (1) for admitting the liquid, a neck (2) for admitting the gas, and an injector tube (3). The injector tube is prolonged by a chamber (5) whose diameter is equal to or greater than that of the injector tube with which it possibly merges. Also described is the application of this device to treatments such as chemical, biochemical or metabolic reactions involving the transfer of a gas to a liquid phase.
