An evaporation system for spray evaporating undesired water comprising: a first pump, a container comprising a sump, a second pump, a spray manifold comprising a spray nozzle, a packing system disposed within the container, a third pump, and an air system comprising an air blower and an air preheater is disclosed. An outlet of a water inlet is connected to an inlet of the first pump. A first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water. A second portion of the ceiling is adjacent to an upper edge of a wall of the container. An outlet of the first pump is connected to an inlet of the container. An inlet of a draw line is disposed in the sump; and an outlet of the draw line is connected to an inlet of the second pump. An outlet of the second pump is connected to an inlet of the spray manifold. The spray nozzle discharges water droplets onto the packing system. An inlet of the third pump is connected to an outlet of the sump. An outlet of the third pump is connected to a discharge outlet. The air system is disposed through the wall of the container; and the air system discharges air flow counter to and/or crossways to the water droplets from the spray nozzle. A method of using the evaporation system is also disclosed.

A sprinkler head nozzle assembly in accordance with an embodiment of the present invention includes a housing including an inlet for pressurize water and an outlet downstream of the inlet, a valve member, operable to extend and reduce an arcuate opening at the outlet of the housing, wherein the size of the arcuate opening indicates the arc of coverage of the sprinkler head nozzle assembly and a rotating distributor, mounted on a central shaft extending through the housing and the valve member, and operable to deflect a flow of water from the arcuate opening out of the nozzle assembly.

A spray nozzle device according to an embodiment includes a first nozzle having a first spray hole for spraying plasma, a second nozzle spaced apart from the first nozzle and having at least one second spray hole through which the plasma sprayed from the first nozzle passes, a coupling member spaced apart from the second nozzle and coupled to the first nozzle, and at least one connecting member connecting the second nozzle with the coupling member. The second nozzle includes at least one inflow channel for the injection of a deposition material into the second spray hole.

A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.

A fire protection sprinkler includes a sprinkler frame and a deflector. The deflector is coupled to the sprinkler frame and distributes fluid discharged from an outlet of the sprinkler in a spray pattern centered about a sprinkler axis and defined by a fluid density in a first quadrant area 2.5 feet (ft.) below the sprinkler and perpendicular to the sprinkler axis, the first quadrant area having a first corner disposed along the sprinkler axis with a first edge extending in the direction of a fluid supply pipe, a second edge extending perpendicular to the first edge and intersecting the first edge at the sprinkler axis, the first quadrant area being defined by a grid of one square foot areas totaling an area of no more than 10 ft.×10 ft., the total fluid density being at least 15 gpm/sq. ft.

Various implementations include a feedback type and jet interaction-type fluidic oscillator devices with atomized output. The device includes first and second fluidic oscillators. Each of the first and second fluidic oscillators include an interaction chamber, a fluid supply inlet, an outlet nozzle, and first and second feedback channels. The first feedback channel of the first fluidic oscillator share a common intermediate portion such that the first feedback channels are in fluid communication with each other, causing the fluid streams exiting the outlet nozzles of the first fluidic oscillator and second fluidic oscillator to oscillate in phase with each other. The outlet nozzle of the first fluidic oscillator and the outlet nozzle of the second fluidic oscillator are structured such that the fluid streams exiting the outlet nozzle of the first fluidic oscillator and the outlet nozzle of the second fluidic oscillator collide with each other, creating an atomized spray.

A cartridge for use in a showerhead or tap is designed for dispensing a liquid, in particular water or a water-based mixture. The cartridge comprises a set of at least two nozzles arranged to create colliding jets of the liquid and thereby create a spray of droplets of the liquid, and a spray shaper for guiding the spray. An inner diameter of the nozzles is between 0.8 and 1.5 millimetres, and a throat of each of the nozzles, along which the nozzle has a constant diameter, has a length that is at least three times this inner diameter.

Irrigation nozzles are provided that irrigate a full circle coverage area with different maximum throw radiuses. The nozzle may include two bodies, one nested within the other, that acting together form the full circle coverage area. The two bodies collectively define an annular exit orifice with one of the bodies defining the inner radius and the other body defining the outer radius. A flow restrictable inlet may be used to adjust flow through the nozzle and to adjust the maximum throw radius. The nozzle may also include a flow reduction valve to reduce the throw radius from a maximum distance and may be adjusted by actuation of an outer wall of the nozzle. A deflector for use with an irrigation nozzle is also provided.
