The mixing nozzle has a throat section, a diffuser section, a gas nozzle section, a first liquid suction port, a liquid nozzle section, a second liquid suction port, a baffle plate, and a jetting port. The first liquid suction port liquidly absorbs the solution in the water storage pool from a side of the gas nozzle section toward the gas nozzle tip. The liquid nozzle section extends to the downstream side of the gas nozzle section with intervening the first liquid suction port. The second liquid suction port liquidly absorbs the solution in the water storage pool from a side of the liquid nozzle section toward the liquid nozzle tip. The baffle plate is provided such that the mixed flow mixed in the diffuser section collides in front of a downstream end of the diffuser section, and divides and reverses the mixed flow.

An apparatus for mixing a liquid and a substance, including a housing with a liquid inlet and a substance inlet to a mixing chamber, an outlet for a mixture of liquid and substance, and a flow restrictor arranged in the housing, between the liquid inlet and the mixing chamber. The flow restrictor is controllable to switch between a first position providing a first through flow area configured to create a Venturi effect such that a flow of the liquid draws the substance into the mixing chamber, and a second position providing a second through flow area that is larger than the first through flow area to thereby decrease a pressure drop caused by the flow restrictor.

A system for introducing gas from an unconventional source into a gas grid pipeline includes a passive blender (10) that introduces gas from an unconventional source (1) into a gas grid (2), the passive blender (10) having gas inputs (3, 11) from the unconventional source (1) and the gas grid (2) and a blended gas output (12), and wherein an internal flow path within the passive blender (10) is shaped and sized to provide entraining and mixing of the gases. The passive blender (10) acts to entrain gas from a gas grid (2) through input (11) by utilising the flow of gas from an unconventional source (1) through input 3, proportionally blending inputs 3 and 11 before outputting the blended gas back to the main gas grid (2). The system comprises the passive blender (10) of the present invention, a first gas input pipe (11) from a grid gas pipeline (2) into the passive blender (10) a second gas input pipe (3) from the unconventional source (1) into the passive blender (1), and an output pipe (12) from the passive blender (10) into the grid gas pipeline (2). The blender (10) and system of the present invention are advantageous in that they can greatly reduce the necessary conditioning of unconventional gas before it is introduced into a gas grid supply (2) without additional means of flow motivation or controls.

A wine aeration device and methods of aerating wine that draw wine from the bottom ⅓ of the container into an aeration chamber where the wine undergoes a first phase of aeration. The wine continues through a return tube into the container where it undergoes a second phase of aeration by way of multiple slits in the return tube causing a venturi effect on the flowing wine.

A water circulation system that includes a pipe assembly for in-line mixing of water and ozone is disclosed. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.

A convergent nozzle is in a flow path from a liquid inlet of the ejector and a liquid outlet of the ejector. A convergent end of the convergent nozzle has a smaller cross-sectional area than an inlet of the convergent nozzle. The convergent nozzle is sized to increase a velocity of the liquid to supersonic velocities and decrease a pressure of the liquid. A low pressure housing includes a low pressure inlet into an interior of the low pressure housing. A convergent-divergent nozzle includes a mixed liquid inlet in fluid communication to receive fluid from the convergent nozzle and the low pressure housing.

A fine bubble generating device is provided, including: a main body, having an inlet, an outlet and a venturi tube mechanism located between the inlet and the outlet, the venturi tube mechanism having a neck portion communicating with outside; a bubble fining mechanism, having at least one passage which is smaller than the inlet in cross-sectional area, the at least one passage communicating with and between the venturi tube mechanism and the outlet. The bubble fining mechanism includes a first vortex member having at least one first slant hole and a second vortex member having at least one second slant hole. The at least one first slant hole and the at least one second slant hole are inclined toward opposite directions, and the first vortex member and the second vortex member is disposed between the venturi tube mechanism and the outlet.

A valve for dispensing a liquid includes a housing, an internal liquid passage extending through the housing, a valve seat, a valve member movable between a closed position engaging the valve seat and an open position disengaging the valve seat, and a control member controlling movement of the valve member, which is movable between a first position in which it engages the valve member in its closed position, a second position in which the valve member is in its open position but still engaging the control member and a third position in which the valve member is in its open position and out of engagement with the control member. At least one air passage connects the outside of the valve with the internal liquid passage. The at least one air passage is closed in the first and second positions of the control member and is opened in the third position.

An apparatus and method for mixing fluids, gases and solids together where the apparatus includes at least two mixing head sections that are mirror images of each other and have abutting surfaces that are abutted together. The at least two mixing head sections have a first bore that extends therethrough from an inlet to an outlet, and at least one second bore whose length is longer than the first bore that extends from the inlet to the outlet.

Wands are used as parts of cleaning systems to conduct cleaning agents into gas turbine engine cores. Wands according to the present disclosure include inlet assemblies adapted to connect to cleaning agents, dispensers adapted to discharge cleaners into gas turbine engines, and conduits that extend from the inlet assemblies to the dispensers.
