A cleaning device for atomizing and spraying liquid in two-phase flow comprising a nozzle provided with multiple liquid bypass pipelines each having liquid guiding outlets inclined at a predetermined angle and an exhaust mesh plate having vertical gas guiding outlets, which makes the high speed liquid flow and high speed gas flow sprayed out therefrom collide against each other sufficiently to form ultra-micro atomized particles with uniform and adjustable size. The ultra-micro atomized particles are sprayed out downwardly to the wafer surface under the acceleration and vertical orientation effects of an atomized particle guiding outlet to perform a reciprocating cleaning for the wafer. Other components such as an ultrasonic or megasonic generation unit, a gas shielding unit, a self-cleaning unit or a rotating unit can also be provided to perform the multifunction of the nozzle.

An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.

An irrigation sprinkler can include a riser and a nozzle mounted at an upper end of the riser for rotation. The sprinkler can include a high flow rate port and a low flow rate port that can each emit a stream of water. The sprinkler can include a diverter valve that can intermittently block or permit the flow of water to the high flow rate port and/or to the low flow rate port as the nozzle rotates. The sprinkler can include a gear train reduction mounted in the riser and coupled to rotate the nozzle. A turbine can be coupled to an input shaft of the gear train reduction and can be rotatable by water flowing through the riser.

In an embodiment, a rotating nozzle including a generally cylindrical interior having an inlet at a circumferential wall adjacent a first end of the body portion and a generally axial exit adjacent a second end of the body portion. A nozzle portion is at least partially received within, and rotatable relative to, the cylindrical interior. The nozzle portion includes an at least partially conical shape, having a relatively smaller cross section adjacent the first end of the body portion. The nozzle portion defines a generally longitudinal flow passage having an inlet opening extending between an exterior of the nozzle portion and the flow passage adjacent the first end of the body portion and a generally axially oriented exit adjacent the second end of the body portion. The rotating nozzle further includes end cap disposed at least partially enclosing the cylindrical interior adjacent the first end of the body portion.

A controlled droplet application (CDA) nozzle has a CDA nozzle cone having a first axis of rotation in a first position and, after adjustment, a second axis of rotation in a second position orthogonal to the first. A rotationally adjustable directional shroud surrounds at least a portion of the cone, the directional shroud blocking at least a portion of a lip of the cone regardless of whether the cone is positioned in the first or second axis of rotation.

An atomization device includes a pair of counter-rotating rollers, a fluid source configured to coat at least one of the rollers in a feed fluid, and a baffle unit. The counter-rotation of the rollers stretches the feed fluid into a fluid filament between the two diverging surfaces of the rollers. The stretched fluid filaments break into a plurality of droplets at a capillary break-up point of the feed fluid. The baffle unit introduces a baffle fluid within the interior of the device and the baffle fluid transports formed droplets of the feed fluid from the atomization device. Excess or misguided atomized fluid droplets are collected by the baffle unit and are recycled back into the device for use in later atomization processes. The variation of atomization device parameters allows for the selection of droplets having desired physical parameters.
