  • Patent number: 10220398
    Abstract: The invention relates to a new atomizing device with improved droplet formation. Smaller droplets are formed with increased micronized volume throughput, wherein high volumes of air are fed to a liquid sprayed from a liquid nozzle (2). High volume ratios result in mean free path between droplets being conveyed so as to minimize collisions and to prevent aggregation of the droplet.

The premix chamber is a component of a male plug which fits into a female housing in the system. Then the system injects a gas into the premix chamber to initiate generation of the foam from the fluid. The foam flows from the premix chamber into a sealed helical channel formed by a helical indentation on an outside surface of the male plug and an inner surface of the female housing to allow the foam to reach a desired state along a length of the sealed helical channel. In the last operation of the method, the foam outputs from an exit end of the helical channel through the male plug to a component of the system.

    Abstract: A nebulization system, which creates a uniform fog of tiny suspended liquid droplets, to lubricate the surfaces of MEMS devices. These droplets fall over the edge of a baffle and are then mixed with an umbrella-like sheet of N2 turbulation gas to generate a uniform cloud of droplets that fill a passivation chamber. The MEMS device is then positioned in this uniform cloud of lubricant droplets for a specified amount of time, thereby uniformly lubricating all the surfaces of the device. The system uses a laser monitoring approach to control the uniformity of the lubricant cloud by providing feedback to the system to control the flow of gases. The system also equalizes the pressure around the sample device seal to prevent gases from entering or exiting the chamber and thereby influencing the environment inside the chamber.

The nozzle also has one or more first auxiliary passages, which may be arranged in an annular pattern around the fuel injector passage, and which terminate at first outlets. The nozzle furthermore may have one or more second auxiliary passages, which also may be arranged in an annular pattern around the fuel injector passage, and which terminate at second outlets. The first auxiliary passages and second auxiliary passages are adapted to supply nitrous oxide or other additional combustion reactants to the engine. The nozzle may be attached to an engine intake and may be adapted to fit between a fuel injector and an engine without substantial modification to the engine.

  • Patent number: 6994276
    Abstract: A device for mixing fluids, in particular a gas injection valve, nozzle valve, mixing nozzle or jet compressor, is proposed. To that end, a first fluid-carrying device (12) for carrying a first fluid and a second fluid-carrying device (13) for carrying a second fluid are provided; the fluids are mixed with one another in a mixing region (16) that is in communication with the fluid-carrying devices (12, 13). In addition, a means (20) for generating turbulence in the applicable fluid and a heater, with which the fluid can be heated before reaching the mixing region (16), disposed downstream of the means (20) for generating turbulence in terms of the flow direction of the applicable fluid are associated with at least one of the fluid-carrying devices (12, 13). The proposed device is used in particular for mixing hydrogen and saturated steam and to deliver this mixture to a fuel cell.

  • Patent number: 6936227
    Abstract: A feed-dispersion system for hydrocarbon feeds of fluid catalytic cracking units is described, which comprises: a feed-injection system made up of two concentric conduits, where the atomization fluid flows through the inner conduit, while the liquid feed flows through the annular space formed by the outer surface of the inner conduit and the inner surface of the outer conduit; an atomization unit having nozzles arranged in rows, with one row having central nozzles connected to the inner conduit for atomization fluid, and two or more rows of side nozzles, connected to the outer feed conduit, the central nozzles and side nozzles of the atomization unit being geometrically placed so that the energy of the atomization fluid is fully transferred by contact to the flow of feed, this resulting in the complete atomization of the feed; a mixing chamber formed by the edges of the central nozzles, the dimensions of which are able to prevent the coalescence of the formed oil droplets.

  • Patent number: 6899289
    Abstract: The invention relates to a nozzle (10) for mixing a gaseous fluid such as air and a liquid such as water and for ejecting an atomized mist of liquid droplets. The nozzle includes a nozzle body defining first (60), second (44) and third (52) annular passages along the length thereof. Pressurized fluid is introduced into the first annular passage (60) and a first restricted annular orifice (68) leads from the first annular passage (60) to the third annular passage (52). Liquid is introduced into the second annular passage (44) and a second restricted annular orifice (48) leads from the second annular passage (44) to the third annular passage (52). Liquid and gaseous fluid are aggressively mixed in the third annular passage (52).

  • Publication number: 20040251320
    Abstract: The present invention relates to a nozzle for mixing at least two fluid substances together for coating a surface with a reaction product of said fluid substances and possibly a reaction product of the aforesaid substances and the surface material to be sprayed with them, said nozzle comprising substantially concentric channels for each fluid substance, the orifices of said channels being disposed close to each other at the end of the nozzle. According to the invention, between the concentric channels for fluid substances to be mixed together, the nozzle has a likewise substantially concentric intermediate channel connected to a compressed air source, the orifice of the intermediate channel connected to the compressed air source has a tapered form and a diameter at most equal to the inner diameter of the intermediate channel, and the orifice of the intermediate channel is directed obliquely towards the center axis of the nozzle.

    Abstract: A method of forming droplets comprises flowing a liquid through a channel; spreading the liquid into a thin film in the channel; and impinging the thin film with a flowing gas to atomize the liquid into droplets. The droplets may then be dried to produce dried particles, such as particles comprising a pharmaceutical active agent. The droplets formed by the disclosed process have improved size and/or size distribution characteristics.

  • Patent number: 6729561
    Abstract: A cleaning nozzle includes a mixing portion with inner walls thereof formed of quartz given smoothing treatment. As a result, the inner walls of the mixing portion have smooth surfaces. This construction effectively suppresses abrasion of the inner walls of the mixing portion, and particle generation from the cleaning nozzle. Further, the cleaning nozzle has a supply pipe surrounding a gas introduction pipe. This reduces areas of contact in the mixing portion between a gas and inner walls of the cleaning nozzle, to suppress particle generation with increased effect.

  • Patent number: 6338444
    Abstract: A spray nozzle has a pre-chamber and a mixing region. A first inlet defines a first fluid flow path for admittance of a first fluid to the pre-chamber. A second inlet defines a second fluid flow path which is crossed by the first fluid flow path for admittance of a second fluid to the pre-chamber. A wall is positioned between the pre-chamber and the mixing region and has an aperture therethrough coaxial with the first fluid flow path. Fluid can pass from the mixing region out of the spray nozzle through an outlet, the outlet not lying on the first and second fluid flow paths. A first fluid entering through the first inlet mixes with a second fluid entering through the second inlet in the mixing region prior to the mixed first and second fluids passing out through the outlet.
