Disclosed are systems and methods for continuously producing dry water from silica and water and from silica, sodium bicarbonate, and water.

A static mixer includes a series of mixing elements, at least some of which are a double wedge mixing baffle. The double wedge mixing baffle includes first and second dividing panels oriented transverse to each other, first and second deflecting surfaces projecting from opposite sides of the first dividing panel, and third and fourth deflecting surfaces projecting from opposite sides of the second dividing panel. One or each of the deflecting surfaces includes first and second planar surfaces arranged at different angles relative to the fluid flow. The double wedge arrangement reduces retained waste volume within the mixer while further manipulating the flow characteristics of fluid flow entering and exiting the mixing baffle, to thereby optimize mixing performance.

A mixer for a vehicle exhaust system includes a mixer body defining a mixer central axis and having an inlet configured to receive engine exhaust gas and an outlet. The mixer further includes an upstream baffle positioned within the mixer body and a downstream baffle positioned within the mixer body to be spaced from the upstream baffle in a direction along the mixer central axis. A doser defines a doser axis and is positioned to spray a reducing agent into an area between the upstream baffle and the downstream baffle such that a mixture of reducing agent and exhaust gas exits the outlet. The mixture moves through a rotational flow path that is at least 360 degrees before exiting the outlet.

Provided is a method for manufacturing a microbicide having high microbicidal performance for eradicating microbes. This method for manufacturing a microbicide comprises: a step for preparing an inorganic aqueous solution containing an inorganic component having seawater as a raw material thereof, an ozone mixing step for mixing ozone into the inorganic aqueous solution, and a stirring step for stirring the inorganic aqueous solution mixed with ozone and passing through a bubble generation nozzle; wherein, the temperature of the inorganic aqueous solution in the ozone mixing step and the stirring step is 0° C. to 30° C., and when the amount of inorganic aqueous solution treated in the ozone mixing step and the stirring step is defined as X liters and the treatment rate of the ozone mixing step and the stirring step is defined as Y liters/minute, then the microbicide is manufactured by alternately repeating the ozone mixing step and the stirring step for A.Math.X/Y minutes (where A is 30 or more).

A fluid mixing device is provided with a plurality of flow channel units disposed to be divided in a plurality of layers. Each of the flow channel units has an inflow port, an outflow port, and a plurality of branch flow channels making the inflow port and the outflow port communicate with each other. The flow channel units located in different layers are connected to each other at the inflow port and the outflow port between the flow channel units, thereby configuring a three-dimensional flow channel as a whole. When the direction from the inflow port to the outflow path of each flow channel unit is set to be a flow direction in the flow channel unit, the flow directions intersect each other between the respective layers.

A mixing unit includes a mixing body having mixing elements that are stacked in a stacking direction and that extend in an extending direction. The mixing elements have a plurality of first through holes to form a flow path therein, and are arranged such that part or all of the first through holes in one of the mixing elements communicate with first through holes in the adjacent mixing elements to allow fluid to be passed in the direction in which the mixing element extends

Disclosed is a water dispensing machine and a carbonated beverage dispensing system which facilitates a combination of carbon dioxide with water in a configuration which provides a smaller footprint and reduces or eliminates dependency on remotely located carbon dioxide tanks and flavoring systems. The system may be configured to produce only carbonated water or to allow the user to select carbonated water or chilled water, and, alternatively, ambient, unchilled water. A carbonator of the system introduces carbon dioxide to a chilled water stream using an injector with slots. This inline, on demand carbonation system provides benefits over carbonator tank systems which carbonate large volumes of carbonated water in bulk.

This disclosure relates generally to selective flocculation, and more particularly to portable test-device for performing selective flocculation experiments in continuous mode. The test-device includes a slurry inflow system, a flocculant tank, a static mixer, a control pumping system, and a thickener system. The static mixer is connected to the slurry inflow system and the flocculant tank, to receive and mix flocculant solution and slurry and cause formation of floc. The control pumping system connects the flocculant tank and the slurry inflow system to the static mixer to control the control parameters responsible for pumping the slurry and flocculant solution in the continuous mode in the static mixer. The thickener system comprises a thickener tank to receive treated slurry and the floc from the static mixer, separately collect tailings and the floc from the thickening tank. The components of the portable test-device are removably connected to each other.

A static spray mixer for the mixing and spraying of at least two flowable components is proposed having a tubular mixer housing (2) which extends in the direction of a longitudinal axis (A) up to a distal end (21) which has an outlet opening (22) for the components, having at least one mixing element (3) arranged in the mixer housing (2) for the mixing of the components as well as having an atomization sleeve (4) which has an inner surface which surrounds the mixer housing (2) in its end region, wherein the atomization sleeve (4) has an inlet channel (41) for a pressurized atomization medium, wherein a plurality of grooves (5) are provided in the outer surface of the mixer housing (2) or in the inner surface of the atomization sleeve (4) which respectively extend toward the distal end and which form separate flow channels (51) between the atomization sleeve (4) and the mixer housing (2) through which the atomization medium can flow from the inlet channel (41) of the atomization sleeve (4) to the distal end (21) of the mixer housing (2). The inlet channel (41) is arranged asymmetrically with respect to the longitudinal axis (A).
