Provided is a coal-containing wastewater spraying device for dust suppression during coal conveying, including a motor, a gland, a body seat, and an accelerator. The body seat includes a funnel-shaped cover, a first disc and a plurality of crushing plates. The accelerator includes a circular second disc. The end of an output shaft of the motor passes through the first disc to connect with the second disc. The cover is provided with a water retaining ring between the first disc and the second disc along its axial direction. The cover, the first disc, the second disc and the water retaining ring form a water inlet space.

BUILDING FEATURE APPLIED IN AIR-CONDITIONING APPLIANCE, capable of enriching the air with atomized water droplets in two stages, where in a first moment the water sent directly from the water supply network is pre-atomized in an appliance (8); being then delivered to the main atomizer (9), which produces the final atomization, creating an ultrafine mist that facilitates the thermal exchange between the mist and the air. The air-conditioning appliance must be associated to a fan so as to spread this mist to the room.

A liquid atomization device includes: an inlet; an outlet; and a liquid atomization chamber. The liquid atomization chamber is provided in an air passage between the inlet and the outlet. The liquid atomization chamber includes a rotary shaft, a pumping pipe, a collision wall, a reservoir, and a drain port. The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.

A spray system includes a spray applicator configured to apply a fluid to a target. The spray system also includes a rotary bell cup of the spray applicator, a splash plate of the spray applicator coupled to the rotary bell cup, and a fluid tip of the spray applicator. The fluid tip is configured to output the fluid onto the rotary bell cup. The fluid tip includes a fluid tip passage extending along a longitudinal fluid tip axis of the fluid tip. The longitudinal fluid tip axis intersects with the splash plate of the spray applicator. The fluid tip also includes a fluid exit port configured to output the fluid from the fluid tip passage onto the rotary bell cup. The fluid exit port extends along a fluid exit axis disposed at an angle relative to the longitudinal fluid tip axis of the fluid tip.

A showerhead is provided having a housing, a perforate partition and a nozzle body. The housing has a fluid inlet and a fluid outlet. The perforate partition is provided in the housing between the inlet and the outlet and has at least one peripheral fluid passage communicating with the fluid inlet. Each peripheral fluid passage communicates at a downstream end with an inwardly extending peripheral slot, and each slot communicates at a downstream end with a mixing cavity. The nozzle body is carried by the housing downstream of the mixing cavity and has a compression port at an upstream end and an outlet port at a downstream end in fluid communication with the compression port.

A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has two nozzle tubes, one inside of another. Each of the tubes has a respective pattern of one or more slots or holes. As the tubes rotate, one with respect to the other, part of the pattern of the one coincides at times with part of the pattern of the other, resulting in a jet of fluid directed toward a filter to remove debris from the filter. The filter is rotated so the jet can reach all parts to be cleaned. The respective patterns of the two nozzle tubes may be an approximation of a helix and/or an approximation of a line.

A texture material applicator and a method for applying texture material to a wall or ceiling surface to produce a desired surface texture and appearance. A selected one of several different rotary dispenser inserts is rotated within a chamber in a body of the applicator, picking up a quantity of texture material on each of a plurality of spatter elements. The spatter elements are resiliently bent by a regulator and throw bits or drops of texture material out from the chamber and radially outward through an outlet opening in the body of the applicator as the spatter elements spring away from a release edge of the regulator. Different textures may be provided by using different rotary dispenser inserts having different spatter elements differently located on the rotary dispenser.

Disclosed is a dosing system for a turbocharger turbine of an exhaust system for an internal combustion engine, the dosing system comprising a distribution device and a metering device. The distribution device comprises a receiving surface, and at least one distribution surface. The receiving surface is equipped to receive exhaust additive dosed to the distribution device. The distribution surface is in fluid communication with the receiving surface and is equipped to distribute exhaust additive in an exhaust stream passing through the turbocharger turbine by a rotary motion of the distribution device. The distribution device is attached to a shaft or hub of the turbocharger turbine. The metering device comprises a supply channel, a metering valve, and a dosing pipe arranged downstream of the metering valve in the direction of flow of reductant when dosing. The metering device is arranged to supply exhaust additive to the receiving surface of the distribution device.

A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has a first tube inside a second tube. Each of the tubes has a different pattern of one or more slots or holes. One tube rotates while the other is fixed, so that part of the pattern of one coincides with the other at times, resulting in a jet of cleaning fluid that removes debris from a filter. The filter is rotated so the jet can reach all parts to be cleaned. The pattern of the rotating tube may approximate a helix and the pattern of the fixed tube may approximate a line.
