The present invention provides a desulfurization agent mixing system for fuel oil used in harbors, the system including: a fuel oil tank for storing fuel oil; a desulfurization agent tank for storing a desulfurization agent; a line mixer receiving and mixing the fuel oil and the desulfurization agent from the fuel oil tank and the desulfurization agent tank; a droplet atomization unit for forming droplets of a mixture of the fuel oil and the desulfurization agent, the mixture being generated by the line mixer; a magnetization unit for magnetizing the mixture in which the droplets are contained; a vortex reaction unit for turning the mixture of the fuel oil and the desulfurization agent, which is magnetized by the magnetization unit; a gas separation unit configured to separate gas contained in the fuel oil and the desulfurization agent mixture in the vortex reaction unit; a collision emulsion unit configured to cause the mixture of the fuel oil and the desulfurization agent from which the gas is separated by the gas separation unit to collide against a collision target; and an emulsion tank for storing the mixture of the fuel oil and the desulfurization agent, which is collided by the collision emulsion unit.

Proposed is a method of emulsifying fuel oil and a desulfurization agent. The method includes (a) a step of adding a desulfurization agent to fuel oil for line mixing thereof, (b) a step of generating droplets in the resulting mixture of step (a), (c) a step of causing the resulting mixture of step (b) to pass through a magnetic field so that the mixture can be magnetized, (d) a step of subjecting the resulting mixture of step (c) to vortex mixing, and (e) a step of causing collision of the resulting mixture of step (d). The method uses fuel oil as a continuous phase and a water-based desulfurization agent as a disperse phase and emulsifies the desulfurization agent in the fuel oil through water-in-oil (W/o) emulsification so that the desulfurization agent can be stably dispersed in the fuel oil. Since the fuel oil and the desulfurization agent are burned together during combustion, sulfur oxides that may occur during the combustion are removed, whereby sulfur oxide emissions are reduced.

Provided is an ultrafine bubble generating apparatus capable, when generating nanobubbles in a liquid, of appropriately mixing a gas into a liquid ejected from a liquid ejector. The ultrafine bubble generating apparatus includes a liquid ejector for ejecting a liquid, a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector, and an ultrafine bubble generator for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. Between the liquid ejector and the ultrafine bubble generator, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the ultrafine bubble generator.

Provided is a liquid supply apparatus which is capable of directly taking in a liquid from a flow channel and appropriately mixing a gas into the liquid when generating-nanobubbles in the liquid using an ultrafine bubble generating apparatus. The liquid supply apparatus comprises a flow channel for a liquid supplied from a liquid supply source and an ultrafine bubble generating apparatus for generating nanobubbles in the liquid. The ultrafine bubble generating apparatus is provided with: a liquid ejector for ejecting the liquid taken in from the flow channel; a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector; and a nanobubble-generating nozzle for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. The pressure of the liquid in the flow channel flowing into the liquid ejector from the upstream-side of the liquid ejector is a positive pressure and, between the liquid ejector and the-nanobubble-generating nozzle, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the nanobubble-generating nozzle.

A beverage supplying apparatus that supplies a beverage into a beverage container, includes: an ingredient storage unit to store a beverage ingredient; a compressed gas supplying means to supply compressed gas to the ingredient storage unit and pressurize the beverage ingredient; and a beverage supplying means to, when receiving a supply command, allow the pressurized beverage ingredient to be supplied to a nozzle, and supply compressed nitrogen gas to the nozzle, so that the nitrogen gas and the beverage ingredient are mixed and stirred at the nozzle and the beverage is discharged to the beverage container through the nozzle.

Disclosed is an assembly for mixing fluids (i.e., gases or liquids), and more particularly an assembly that accurately mixes two or more high-pressure fluid sources and is adapted for use in applications, such as for example, chromatography. The mixer assembly (100) includes, inter alia, a housing (10), an inlet fitting (40), and a mixer cartridge assembly (60). The housing (10) has a fluid receiving section (16) and a fluid discharge section (18) with an outlet (20) formed therein. A central bore (22) extends between the fluid receiving section (16) and fluid discharge section (18). An inlet fitting (40) is engaged with the housing (10) and has first (42) and second (44) fluid ports formed therein that extend from the fitting exterior to the fluid receiving section (16) of the housing (10). A mixer cartridge assembly (60) is disposed within the central bore (22) of the housing (10) and is positioned between the inlet fitting (40) and the downstream end portion of the housing (10). The mixer cartridge assembly (60) includes a body portion (64), a plurality of spheres disposed within a central mixing chamber (62) formed in the body portion (64), and mechanism for retaining the spheres in the mixing chamber (62).

A vehicle exhaust system includes an outer housing defining an internal cavity surrounding an axis, an inlet baffle configured to direct engine exhaust gas into the internal cavity, and an injector that is configured to spray a fluid into the internal cavity to mix with engine exhaust gas. An inner wall is spaced radially inward of an inner surface of the outer housing to define a gap. The inner wall has an impingement side facing the axis and a non-impingement side facing the gap. At least one heat transfer element is positioned within the gap and in is contact with at least one of the inner surface of the outer housing and the non-impingement side of the inner wall to transfer heat through the inner wall to the impingement side to reduce spray deposit formation.

A liquid treatment apparatus (10) for processing a liquid includes an inlet nozzle (12) having an orifice (16) for directing a flow of liquid through the orifice (16) to define a fluid jet, and a concial diffuser (18) including a tip (20), a base portion (22), and a curved surface (26) therebetween. The conical diffuser (18) is generally aligned with the orifice (16) such that the fluid jet impacts upon the tip (20) of the conical diffuser (18). Moreover, the curvature of the curved surface (26) is selected to maintain a substantially constant Froude number of the liquid along the conical diffuser (18).

A counterflow mixing device for a process chamber is disclosed, comprising an injection tube that introduces a fluid in a manner counter to a flow of a post-plasma gas mixture traveling downward from a plasma source. The invention allows for proper mixing of the fluid as well as avoiding recombination of generated ions and radicals.

A low flow apparatus for creating a solution in water of a solid chemical is provided. Also provided is a cartridge containing a solid chemical which may be placed into the apparatus. Further provided is a method of using the apparatus to create a chemical solution form a solid chemical.
