Abstract:
Spray heads for use with desuperheaters and desuperheaters including such spray heads. One example of a spray head includes a main body having an exterior surface and defining a central passage, the main body adapted for connection to a source of fluid, at least one entrance port formed in the main body along the central passage, and at least one spray nozzle arranged adjacent the exterior surface of the main body. The spray head also includes a plurality of flow passages, each of the plurality of flow passages providing fluid communication between the entrance port and an exit opening of the spray nozzle. A first one of the plurality of flow passages follows a first non-linear path and has a first distance, and a second one of the plurality of flow passages follows a second non-linear path and has a second distance different from the first distance.
Abstract:
The inventive concept relates to a swirler. According to an aspect of the inventive concept, there is provided a swirler including a casing, a pilot body disposed in the casing, and a plurality of vanes arranged along a circumference of the pilot body, wherein at least a part of the vane protrudes further to a downstream than an end portion of the pilot body.
Abstract:
A method for producing a spray jet from a liquid/gas mixture with a two-component nozzle having a nozzle housing, including the steps of blending a supplied liquid and a supplied gas and producing a spray jet consisting of gas and liquid drops, producing a gas jet and mixing of gas jet with the spray jet.
Abstract:
A dual function aerosol valve assembly has a valve housing with first and second stem valves mounted for reciprocation within it. The first stem valve controls flow of gaseous propellant and the second stem valve is coaxially received within the first stem valve and controls flow of product. An actuator and nozzle assembly is connected with the stem valves so that the first stem valve is opened to admit propellant to the nozzle upon initial depression of the actuator, and the second stem valve is then opened to admit product to the nozzle. Closing of the stem valves is in reverse order so that flow of product to the nozzle is first interrupted and then flow of propellant is interrupted. A spring biases the stem valves to their closed positions. The valve housing is constructed to accommodate either a bag-on-valve system or a piston system.
Abstract:
A system for delivering vortex rings to an intended target includes a vortex ring generator, one or more component storage containers, and a component additive mechanism. The vortex ring generator is configured to deliver and air vortex rings. The component additive mechanism is configured to remove a component from at least one of the one or more component storage containers, generate a gas from the component, and to add the gas to a vortex ring after the vortex ring is generated by the vortex ring generator.
Abstract:
A coating device for coating an inside of a hollow body with an atomized fluid has at least one atomizing tube enclosing an atomizing channel. A pressurized propellant gas for atomizing an unatomized fluid can be introduced into the atomizing tube. The atomizing tube has at least one outlet opening and further has at least one hollow needle having a discharge opening for the unatomized fluid. The at least one hollow needle interacts with the atomizing channel and is arranged essentially coaxially thereto. The atomizing tube and the hollow needle form a Venturi arrangement.
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.
Abstract:
A two-fluid nozzle is provided. The two-fluid nozzle includes a main nozzle, a mixing chamber and a nozzle orifice connected to the mixing chamber and positioned downstream of the mixing chamber. A ring of secondary air nozzles surrounding the nozzle orifice is also provided.
Abstract:
An object of the present invention is to provide a film formation device that is able to prevent a size increase in a configuration around a mist jet nozzle while maintaining uniform spouting of a mist to a substrate on which a film is to be formed. The present invention includes a mist generator (2) that generates a mist of a raw material of a film to be formed, and a mist jet nozzle (1) that jets the mist generated by the mist generator to a substrate on which a film is to be formed. The mist jet nozzle includes: a main body (1A) having a hollow portion (1H); a mist supply port (5a) that supplies the mist; a spout (8) that jets the mist to the outside; a carrier gas supply port (6a) that supplies a carrier gas; and a shower plate (7) having a plurality of holes (7a) formed therein. By the arrangement of the shower plate, the hollow portion is divided into a first space (1S) connected to the carrier gas supply port and a second space (1T) connected to the spout. The mist supply port is connected to the second space.
Abstract:
Disclosed is a catalyst injection nozzle that comprises an outer tube with an open end, a nozzle tip with a diameter connected to the outer tube open end, an orifice connected to the nozzle tip internal to the outer tube, an internal mixing zone connected to the orifice internal to the outer tube, an inner tube residing within the outer tube further comprising an open end connected to the internal mixing zone, where a steady-state, uniform two-phase flow regime between an atomizing gas and at least one liquid catalyst feed does not form in the internal mixing zone at an atomizing gas to liquid catalyst feed flow ratio of about 0.05 to about 10.
