An electrostatic sprayer operable at high flow rates and low pressures particularly suitable for spray drying. The sprayer includes an elongated body having a downstream spray nozzle assembly through which electrically charged liquid is directed via a central feed tube within the nozzle body and atomizing air is supplied via an annular passage about the liquid feed tube. In one embodiment, the nozzle assembly is an external mix cluster head spray nozzle assembly having a plurality of circumferentially spaced metallic spray tips. In another embodiment, the spray nozzle is an internal mix nozzle assembly having a spray tip with an internal mixing chamber for atomizing liquid prior to discharge.

A dual media spray nozzle assembly for cleaning an optical viewer or sensor lens is disclosed. The assembly includes two media pathways that terminate in two arrays at the target cleaning area. The nozzle arrays are coplanar. The two media may be activated sequentially or simultaneously. The assembly includes a cover, a spray element, and a media inlet body. The nozzles are formed in a curved, semi-annular opening of the spray element. The spray element includes front and back sides. Formed on the front side is a first media flow path associated with a first media inlet formed on the media inlet body. The first media flow path is associated with the first array of nozzles. Formed on the back side is a second media flow path associated with second media inlets formed on the media inlet body. The second media path is associated with the second array of nozzles.

One aspect of the present invention relates to a device for managing a fine particle concentration of a target region by supplying charges to a target region, the device comprising: a container configured to store liquid, at least one nozzle configured to output the liquid, a pump configured to supply the liquid from the container to the at least one nozzle, a power supply configured to supply power to the device, and a controller configured to supply the charges to the target region through the at least one nozzle by using the power supply, wherein the controller is configured to, by using the power supply, apply a voltage equal to or greater than a reference value to the at least one nozzle, and provide electric force in a direction away from the device to the fine particles in the target region charged by the supplied charges.

A system for spraying products onto glass fibers, designed to spray at least one sizing composition and an anti-dust agent onto the glass fibers includes two separate annular spraying elements which are successively arranged on the path of the glass fibers, the two spraying elements including a first annular element for spraying the sizing composition and a second annular element for spraying the anti-dust agent, each one embodied by at least one specific annular crown surrounding the glass fibers. The second annular element for spraying the anti-dust agent is arranged downstream of the first annular element for spraying the sizing composition in relation to the path of the glass fibers.

A nozzle head for descaling rolling stock, said rolling stock moving relative to said nozzle head, is adapted to be mounted for rotation about an axis of rotation relative to a surface of said rolling stock. Said nozzle head comprises a plurality of nozzles adapted to spray a liquid on said rolling stock, wherein said nozzles are positioned at different radial distances from said axis of rotation.

A nozzle lance for exhaust gas treatment, a combustion plant with nozzle lances for exhaust gas treatment and a method for exhaust gas treatment in a combustion plant are proposed, wherein an admixing fluid is admixed to the active fluid in the nozzle lance and atomized via three nozzles.

A nucleation nozzle for forming freezing nuclei for devices for making artificial snow, starting from a jet of pressurised liquid, comprising a compressed air duct having an inlet opening and an outlet opening. A first stretch of the compressed air duct has a cross section which decreases in the flow direction of the compressed air, from the inlet opening to the outlet opening. The first stretch is followed by a second stretch having a cross section which increases in the flow direction of the compressed air from the inlet opening to the outlet opening. There is provided at least one water duct having an inlet opening and an outlet opening. The water duct is separate from the compressed air duct. The outlet opening of the water duct is positioned close to the outlet opening of the compressed air duct.

An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

A spray head includes a first plurality of nozzles for emitting water in a first spray pattern and a second plurality of nozzles for emitting the water in a second spray pattern. In at least one mode of operation, the water is emitted from both the first plurality of nozzles and the second plurality of nozzles with the second spray pattern being at least partially encompassed within the first spray pattern; and wherein at least one of the first or second spray pattern is a hyperboloidal shape.

A cluster head nozzle for spraying a fluid, having a single-piece housing and multiple outlet openings which are arranged around a central region on a front side of the housing for individual spray jets, and at least one purge air outlet opening for purge air. The at least one purge air outlet opening and sections of a feed channel for the purge air are provided in the single-piece housing.
