摘要： A combined liquid stirrer and gas injector comprises a suction turbine (5) supplied with gas by a cylinder (6) enclosing the stirrer drive shaft (2). A liquid stirring and gas injection device comprises a vertical drive shaft (2) equipped with an axial flow rotor (4) at its end and fitted with a suction turbine (5). The shaft (2) is enclosed by a cylinder (6), the lower end of which terminates in the turbine and the upper end of which is sealed to the drive and has an opening (14) for gas injection into the annular gap (15) between the shaft and the cylinder. Preferred Features: The turbine (5) consists of a radial vane assembly fixed between two disks (8, 9), the upper disk (8) having a central hole for passage of the lower end of the cylinder (6) which forms, with the hole edge, an annular gap for liquid intake into the turbine. The gas/liquid dispersion, delivered radially from the turbine, is directed towards the axial flow rotor (4) by an annular deflector (16) surrounding the turbine and having a central bottom opening (18), vertical counter-vanes (19) attached radially to the deflector, and optionally an additional stirring rotor. The counter-vanes extend vertically from the liquid (L) surface level over a total height (H) of about 0.7-12 times the turbine diameter (d). The axial flow rotor is a propeller screw (4) and the counter-vanes (19) have radial recesses to allow passage of the screw vanes (4a).

摘要： The present invention relates to a process of oxidation, of the wet oxidation or ozonization type, of a liquid contained in a reactor. The gas of the gas headspace is aspirated into the liquid, and the portion which is not dissolved in the liquid is recovered in the gas headspace. The agitation means creates a flow of liquid immediately adjacent to the end of the duct opening into the liquid, and generates a gas/liquid dispersion in the zone, within which the liquid reacts with the gas, then conveys and ejects the said dispersion at its periphery, such that the gas is dissolved in the liquid in the zone extending from the agitation means to the surface of the liquid. The said process is particularly suitable for oxidations which make use of considerable quantities of oxygen or of ozone. It is particularly applied for the oxidation of papermaking liquors.

摘要： La présente invention a pour objet un procédé d'oxydation de type oxydation par voie humide ou ozonation d'un liquide contenu dans un réacteur. Le gaz du ciel gazeux (20) est aspiré dans le liquide, la partie non dissoute dans le liquide est récupérée dans le ciel gazeux. Le moyen d'agitation (2) crée un flux de liquide à proximité immédiate de l'extrémité du conduit (3) débouchant dans le liquide et génère une dispersion gaz/liquide dans la zone (15), au sein de laquelle le liquide réagit avec le gaz, puis véhicule et éjecte en sa périphérie ladite dispersion, de telle sorte que le gaz se dissout dans le liquide dans la zone (16) s'étendant du moyen d'agitation (2) à la surface du liquide. Ledit procédé convient tout particulièrement pour les oxydations mettant en oeuvre des quantités d'oxygène ou d'ozone importantes. Il est notamment appliqué pour l'oxydation de liqueurs de papeterie.
