Abstract:
Provided is a bubble generating mechanism that does not use a complicated air mixing mechanism and generates micro-bubbles in a sufficient quantity. A flow path (2) that connects an inflow opening (2n) that opens on an inflow end and an outflow opening (2x) that opens on an outflow end is formed in a state passing completely through a member main body (6), and a constricted part (2c) the flow-through cross-sectional area of which is smaller than the inflow opening (2n) is formed in a position within that flow path (2). Colliding parts (3) that further reduce the cross-sectional area of the flow path in the constricted part (2c) are disposed in the constricted part (2c) in a state that divides the axial plane of the flow path (2) into three or more segment areas (2e).
Abstract:
A homogenizing apparatus (1) comprising: —an inlet (2) for receiving a pressurized fluid, possibly also containing solid particles; —a zone wherein homogenization of the fluid takes place; —an outlet (10) for the fluid at a lower pressure with respect to the inlet pressure, wherein, in the homogenization zone, the fluid passes from a zone having a larger diameter (or volume) to a zone having a smaller diameter (or volume), the homogenization zone comprising an interacting element (9) shared by a first stage (equipped with a first deflector plug (6)) and a second stage suitable for creating back pressure (equipped with a second deflector plug (12)), where the deflector plugs (6 and 12) operate with the interacting element (9) they share, generating an increase in the shear rate within the first stage. The invention also concerns a homogenization process.
Abstract:
A homogenizer valve includes two or more pressurized, movable valve cones, two or more valve seats and a valve housing which surrounds the valve cones and the valve seats. The valve cones and the valve seats are disposed so that throttles occur between them, which constitute homogenization gaps, which have a gap height h. The homogenization gaps are disposed at an angle in relation to the horizontal plane. The homogenizer valve is intended to be used in existing homogenizers and has been particularly produced to be able to obtain an efficient homogenization for liquids which are processed at a lower pressure and with a greater flow, such as, for example, pasteurized milk.

Abstract:
A high pressure homogenizer segmentalizes material made of minute solid or the like by passing suspension liquid including the material to a small diameter orifice at high speed under high pressure. An injection valve of the high pressure homogenizer includes: a fixed member having a material introducing passage therein; and a movable member disposed rotatably, swingably, or pulsatingly opposite to the fixed member in an axial direction of the fixed member. The orifice of the injection valve is made of a fine gap in a radial direction disposed between an end face of the fixed member facing an end of the material introducing passage and an end face of the movable member disposed at an end of the movable member opposed to the fixed member. The orifice communicates with a material processing passage via a ring-shaped collision wall.
Abstract:
The invention provides a method for mixing two or more gaseous or liquid streams, where the gaseous streams are combined in an inlet chamber and thereafter repeatedly accelerated and decelerated in one or more of stages, and a value of a maximum linear velocity of the accelerated combined gaseous stream is maintained in each step within a range of mass flow rates of the gaseous streams.The invention also provides apparatus for mixing two or more gaseous or liquid streams, one embodiment comprises a body with a seat; a spindle with a plug, which is installed in the seat and the seat and the plug have a plurality of conical surfaces forming the same plurality of conical annuli. The spindle is able to move the plug in an axial direction in the seat during the mixing.Another embodiment comprises a body, a spindle with a tube plug. A cage and annular mixing elements surround the tube plug.

This invention provides a device and method for creating hydrodynamic cavitation in fluids which includes a flow-through chamber intermediate an inlet opening and an outlet opening; the flow-through chamber having an upstream opening portion communicating with the inlet opening and a downstream opening portion communicating with the outlet opening; the cross-sectional area of the downstream opening portion being greater than the cross-sectional area of the upstream opening portion; and at least two cavitation generators located within the flow-through chamber for generating a hydrodynamic cavitation field downstream from each respective cavitation generator.
Abstract:
A static mixer (1)to emulsify water and/or other additives in gas oil comprises a hollow structure (2) within which two mixing units (23,27) are disposed, each comprising a first and a second mixing bodies (24, 25, 28, 29) each carrying a frusto-conical boundary surface (24a, 25a, 28a, 29a). The boundary surfaces (24a, 25a, 28a, 29a) are disposed mutually opposite in parallel and facing each other so as to define a narrow mixing gap (26, 30) of truncated conical form at which the mixture runs in a condition of substantially laminar flow and is submitted to shear forces causing emulsification. Also proposed is a process for producing a dispersion, which process can be carried out by said mixer (1).
