Abstract: Ejector device for forming a pressurized mixture of liquid and gas, comprising a suction chamber and a diffuser. The suction chamber comprises an injection nozzle for producing a jet of liquid flowing in a longitudinal direction, a gas inlet for admitting into the suction chamber a gas to be driven by the liquid jet, and an outlet opening for discharging the liquid jet and the driven gas from the suction chamber. The diffuser is connected to the outlet opening of the suction chamber and has, in the longitudinal direction, a transversal section that increases from the outlet opening, the diffuser being situated immediately after the outlet opening of the suction chamber.

Abstract: In a method and to a device for treating a compound, such as a chemical and/or organic and/or microorganism compound, which is carried by a liquid, the liquid is driven axially through an axial inlet (21) into a central inlet portion of a radial cavitation chamber (18) having a peripheral outlet (30), such that the liquid is diverted into the central inlet portion and flows into the radial chamber in various radial directions towards the peripheral outlet; and the liquid flow conditions between the inlet and the peripheral outlet of the radial chamber are capable of generating cavitation bubbles or pockets (31) and subsequently causing the collapse or implosion of the bubbles or pockets in order to treat the compound at least partially.

Abstract: The invention relates to a hood for sucking up fine particles, comprising: an air intake mouth comprising a crest intended to be placed close to a wall or to emit fine particles, the crest defining an internal portion of the hood and an external portion; and a suction outlet intended to suck up the fine particles. The hood is characterized in that the mouth further includes an external lip extending towards the suction outlet and having a leading edge located on the same side as the outlet in relation to the crest, so that, when the hood is in operation, the sucked-up air undergoes no separation at the lip and that an air separation zone is located only in the internal portion of the hood.

Abstract: The separator has a cylindrical separator chamber and an impeller on the same axis and driven in rotation. The impeller has a core, an inlet for receiving an axial flow of fluid, an outlet for injecting the fluid into the separator chamber, and guide channels formed between the inlet and the outlet of the impeller at the periphery of the core. The core has a portion of diameter equal to or greater than the inner diameter of the separator chamber. In this portion, the guide channels extend longitudinally, and they then continue as far as the outlet from the impeller, which outlet is cylindrical in shape and of diameter equal to the inner diameter of the separator chamber.

Abstract: A liquid to be homogenized passes successively through two perforated walls (TA, TB) forming jets (F2, F6) on passing therethrough for performing stirring. These two walls extend longitudinally over a common length of the axis (A) of the device. The liquid passes from one to the other by following a circumferential path (F4) and its direction of longitudinal flow is reversed, locally (F5). The invention is particularly applicable to measuring the concentration of one of the components in a mixture.
