Abstract: An apparatus for reducing pollution emitted by an industrial exhaust source comprises a sleeve having an interior cavity, and at least one sidewall. A sprinkler or water injection system supplies water to the interior cavity of the sleeve, and comprises an incoming water tubing assembly for water flow. At least one secondary tube connects the incoming water tubing assembly to a corresponding number of nozzles within the interior cavity, each injecting a plurality of streams or jets of water therein to cleanse out the mix of pollutants.

Abstract: A wet scrubber apparatus has a housing with access doors and guides that allow for the installation of self-contained baffle modules. Selected baffle modules can to be inserted, exchanged, removed or left blank (no baffles) within the wet scrubber housing, depending on the desired process. The wet scrubber allows for variable performance and feature-enhancing for a target efficiency and effectiveness. The wet scrubber can incorporate a pump and pipe manifold “fluidizer” design that can spray water or fluid up onto the modules during operation of the wet scrubber to keep collected material off the baffles. Water can be sprayed throughout the modules onto the baffles during operation, or when the scrubber is offline, isolated from the gas to be scrubbed, during a cleaning operation. This water or fluid can come from an outside source or can be piped and valved to recirculate existing scrub water or fluid.

Abstract: A deaeration device for a fluid includes a reservoir that contains a portion of the fluid, a fluid flow path that carries a portion of the fluid, a pressure regulating structure that creates a pressure gradient along the fluid flow path, a fluid exit in the fluid flow path, and a fluid entrance in the fluid flow path.

Abstract: Clean version of the Abstract A pneumatic type water-free starting self-priming device includes a driving device, and a gas-liquid separation chamber and an expandable gas-liquid separation chamber respectively arranged on two sides of the driving device.

The expandable gas-liquid separation chamber uses shrinkage or expansion of volumes of inner and outer chambers to generate a pressure difference to suck in water, so as to realize water suction, gas-liquid separation and water drainage. Also, the high-speed gas from the driving device flows through the two chambers, so that air can be discharged quickly.

Abstract: An apparatus, system, and method for the extraction of water molecules from the air includes a combination of electrical mechanisms and materials engineering. With the help of hydrophobic and hydrophilic materials on an array of thermally conductive and electrically insulated materials, the extraction of water from the air is significantly increased. A combination of hydrophobic and hydrophilic materials and an electric field gradient moves the water molecules towards the collection system thus speeding up the water formation process. This also inhibits the re evaporation of the water droplets.
