A novel methodology of air purification and apparatus uses thorough air-bath to trap airborne debris and gaseous molecules in the liquid. Incoming air are crushed repeatedly and thoroughly at various stages into tiny air bubbles in contact with liquid in the apparatus where airborne materials and gaseous molecules are trapped in the liquid. This novel cleaning system can effectively remove small or large airborne debris and gaseous molecules, in contrast to cleaning effectiveness limited by the filter pore sizes in traditional filter system. The liquid can be water, water mixed with any designed substances or other type of liquid phase of materials. In exemplary case, water is used as a part of filtration medium, the apparatus thus can be served as both air purifier and humidifier. A relatively high humidity in the air would help to trap more airborne debris, which makes the air purification apparatus more efficient.

The disclosed technology regards a wet dust extractor system with a water/solids separator for filtering slurry from the extractor into residue cakes and filtrate water, and related methods of removing dust from an industrial environment and dewatering resulting sludge. The wet dust extractor system has an air inlet, an impeller fan, and an extraction panel. Water is injected at the inlet of the fan impeller, where it is spun with the incoming dust laden air; the resulting slurry then passes to the extraction panel, which removes the slurry from the system by means of a discharge sump. The slurry then is pumped or otherwise delivered to the separator for filtering slurry into residue cakes and filtrate water. The separator includes a frame supporting a plurality of rollers supporting a filter media belt, a plurality of blades and wipers for cleaning the rollers and removing excess filtrate water and cake material, and an inlet water manifold to distribute slurry water uniformly on the filter media belt. The frame supports a filter bed, with a slurry receiving area having a perforated panel at its base, for receiving, pre-filtering and moving the slurry through the separator, and a filter bed collection tub with an exit aperture for collecting and delivering filtrate to a water holding tank. The filter media belt traverses the plurality of rollers, through and about the filter bed, supported along a portion of its path by the perforated panel. Both a residue cake bin and a clean water holding tank may be provided with the system to collect residue and filtrate water, respectively, for re-use or disposal.

Disclosed is a wet air purifier that eliminates contaminants while contaminated air passes therethrough by causing the contaminated air to come into contact with water. The wet air purifier suctions external air by rotating a rotary fan installed therein and disperses water droplets by causing water to collide with a rotary fan to increase a contact surface between air and water. In the wet air purifier, a mixture of the contaminated external air and the water is made to pass through a long narrow passage and guided to a storage tank in which contaminants are settled. In this way, the wet air purifier increases a retention time and a collision time of water and contaminated air. The wet air purifier also can function as a humidifier.

This disclosure relates to a system that provides an environmentally friendly method to clean air over towns and cities. The system utilizes tourmaline filters and rocks, sunlight, and water to simulate the cleaning properties of waterfalls in order to create an ionized surface within a cylindrical tube and creates raindrops and mist to simulate precipitation. The system eliminates pollutants instead of transferring them to the surrounding environment.

A packed tower includes a packed tower housing having an inlet for receiving an effluent stream; an outlet for venting the effluent stream; a packed substrate housed within the packed tower housing between the inlet and the outlet, the packed substrate being configured to entrain at least some of particles from a fluid as the effluent stream flows therethrough; and a fan housed within the packed tower housing, the fan being configured to propel the effluent stream from the inlet towards the outlet and to remove at least some of the particles from the fluid. The fan helps to generate a negative pressure to draw the effluent stream into the packed tower and through the packed substrate, which reduces the back pressure improves the flow of effluent stream through the packed tower and upstream abatement apparatus and helps to improve the removal of particles from within the effluent stream.
