A nozzle including an exterior surface extending between a first end and a second end of the nozzle. The exterior surface including spray outlets disposed at the second end. An interior cavity is disposed interior to the exterior surface. A first channel and a second channel fluidly connect to the interior cavity. One or more third channels fluidly connect between the interior cavity and an individual spray outlet of the spray outlets. The one or more third channels rotate about a longitudinal axis of the nozzle and angle in a direction away from the longitudinal axis of the nozzle.

A fluid mixing device that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

A nozzle for spraying liquids, in particular a dual-substance nozzle, having a nozzle housing and a plurality of outlet openings in the nozzle housing, wherein each outlet opening is arranged at the end of an outlet passage through the wall of the nozzle housing, and wherein the plurality of outlet openings is arranged in a circle on the nozzle housing. An outlet angle which the respective central axis of the outlet passage associated with the outlet opening encloses with a central longitudinal axis of the nozzle housing differs between at least one first and at least one second outlet opening.

A reductant impingement device includes a proximal end having an impingement pin with a convex surface; and a distal end having a body concentric with a longitudinal axis of the impingement pin. The distal end includes a first surface and a second surface opposite the first surface. A plurality of inner channels connects the first surface and the second surface, and a plurality of outer channels connects the first surface and the second surface, where the plurality of inner channels are disposed in a circular array at a first radial distance from a longitudinal axis of the impingement pin, and the plurality of outer channels are disposed in a circular array at a second distance from the longitudinal axis of the impingement pin.

A particle diameter is decreased and a surface area per unit flow amount is increased by spraying a VOC-containing liquid from a spraying device spraying that is a two-fluid nozzle in a vacuum container, so that only water in the VOC-containing liquid can be greatly evaporated and exhausted, and a concentrated VOC-containing liquid having high concentration can be refined and processed.

A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

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 reductant impingement device includes a proximal end having an impingement pin with a convex surface; and a distal end having a body concentric with a longitudinal axis of the impingement pin. The distal end includes a first surface and a second surface opposite the first surface. A plurality of inner channels connects the first surface and the second surface, and a plurality of outer channels connects the first surface and the second surface, where the plurality of inner channels are disposed in a circular array at a first radial distance from a longitudinal axis of the impingement pin, and the plurality of outer channels are disposed in a circular array at a second distance from the longitudinal axis of the impingement pin.

A nozzle including an interior cavity, a structure disposed within the interior cavity, a first channel fluidly connected to the interior cavity, one or more second channels fluidly connected to the interior cavity, and one or more outlets coupled to the interior cavity. The structure includes a bottom impinging surface that is at least partially concave, one or more legs that support the bottom impinging surface, and a top surface located opposite the bottom impinging surface.

A nozzle including a first end and a second end. The first end includes at least a first inlet and a second inlet and the second end includes a plurality of outlets. An exterior surface extends from the first end to the second end of the nozzle. A plurality of vanes are disposed on the exterior surface and extend from the first end to the second end of the nozzle. A plurality of channels form along the exterior surface of the nozzle.
