This description relates to waste disposal garbage chutes and more particularly to automated air quality management in and around the disposal chute and collection rooms where garbage chutes are present utilizing automated air quality sensing hardware and evacuation devices to provide a clean, sanitary waste room environment. A system according to the present invention includes a 3 step design using an air sensor to determine air cleaning cycle, and an air intake port with specular reflective surfaces in the inside to provide a reflective element to reflect UV light into the airborne particulates thereby killing 99% of the bacteria and fungi before entering an electrified gravity fed fluid filament air filter which collects the dead bacteria and fungi and settles in a collection reservoir. The fluid in the reservoir is then further filtered to clean the fluid for reuse in the automated air cleaning system.

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.

Various methods and apparatus are disclosed that relate to one or more aspects of an abatement system. In various aspects a nozzle assembly of an abatement system includes at least one rotationally adjustable nozzle tubing having at least one nozzle coupled thereto.

Embodiments of a system and a method for preparing mold-resistant paper comprising a wet scrubber assembly in fluid communication with at least one collection plenum disposed at an operational area of a paper manufacturing line. The wet scrubber assembly can be operated to draw a stream of exhaust air from the operational area of the paper manufacturing line through the wet scrubber assembly to remove particulate from the exhaust stream. Such systems and methods can be used to produce mold-resistant paper by coating a paper with an antimicrobial composition including at least one antimicrobial additive at the calendering stage. The collection plenum can be placed in proximate relationship with the calendering stack such that the amount of antimicrobial additive particulate in the air at the calendering stage is reduced. The mold-resistant paper can be used in a gypsum panel.

A method for removing dust from flue gas using an emulsion liquid membrane, including: a) dissolving a surfactant into a membrane solvent to yield a membrane-forming liquid; stirring and injecting an internal phase liquid into the membrane-forming liquid to yield an emulsion; b) stirring and adding the emulsion to an external phase liquid to disperse the emulsion into the external phase liquid to yield an emulsion liquid membrane; c) allowing the emulsion liquid membrane to contact with a flue gas for removing dust; d) separating a dust-loaded emulsion, and demulsifying the dust-loaded emulsion under an electrostatic field to release the dust from the membrane-forming liquid; recycling the membrane-forming liquid to a); and e) allowing the dust released from the demulsification to precipitate in the form of a slurry and discharging the slurry.

Air filtration devices are described for wet air filtration. In exemplary embodiments, an air filtration device includes a housing having an air intake and an air outlet. An air conduit extends between the air intake and the air outlet. A fan is positioned in the air conduit and configured to draw air into the device via the air intake and propel the air through an air channel towards the air outlet. The air conduit includes a liquid introduction section configured to introduce a liquid to the air in the air channel, and a liquid removal section configured to guide the air in a downward helical path downstream of the liquid introduction section configured to separate the liquid from the air using centrifugal force.
