Air filtration assemblies configured to provide instant detection of particles and/or improve particle filtration are disclosed. The assemblies may include an air inlet duct in fluid communication with a compressor of a gas turbine system. The air inlet duct may include an inlet for receiving intake air including intake air particles, and an outlet positioned opposite the inlet. The assembly may also include a plurality of vane filters at the inlet, an array of fabric filters positioned in the air inlet duct, downstream of the vane filters, and a silencer assembly positioned in the air inlet duct, downstream of the fabric filters. Additionally, the assembly may include an electrostatic component positioned in the air inlet duct, downstream of the fabric filters. The electrostatic component may be configured to charge the intake air particles that pass through the vane filters and the fabric filters.

A method of forming a collection electrode for an electrostatic charging air cleaning device. The method includes forming a slurry including a carbon black powder material, a polymeric binder material and a liquid solvent material. The method further includes applying the slurry to a substrate material. The method also includes curing the slurry to obtain a coating layer on the substrate material to form the collection electrode.

An electrostatic charging air cleaning device. The device includes a pre-charger configured to generate a corona discharge to electrostatically charge particulate matter in an air stream. The device further includes a separator downstream from the pre-charger configured to convey the electrostatically charged particulate matter and formed of an insulative material. The device also includes a collection electrode configured to receive and to absorb the conveyed electrostatically charged particulate matter. The collection electrode includes a substrate material and a coating layer coated onto the substrate material. The coating layer includes a carbon black material and a polymeric binder. The substrate material is a metal plate including mechanical perforations.

An air purifier capable of removing hazardous substances and viruses from air. The air purifier further includes: a body having an air inlet formed on a lower end thereof, an air outlet formed on an upper end thereof, and a flow path formed therein to move air upward; a pre-filter disposed in the flow path of the body; a box-shaped cell type discharge device disposed in the flow path of the body to generate active species; a dust collection device in the flow path of the body and having a discharge part with a linear discharge electrode and a dust collection part for collecting the dust charged through the discharge part; an ozone removal device in the flow path of the body to remove ozone generated from the discharge device and/or the dust collection device; and an air fan disposed in the flow path of the body.

Methods and apparatus of the present disclosure monitor and change operation of an air filtering system or apparatus dynamically over time. Changes to the air filtering apparatus may be associated with a type of facility and air purity requirements associated with the type of facility. Examples of different types of facilities include an office building, a clean room, and a hospital. Apparatus of the present disclosure may include conventional air filters and may include disinfecting air filter sub-assemblies that use a high voltage to charge particles in the air such that those particles may conglomerate and be captured more easily in an air. Methods consistent with the present disclosure may change an air flow rate or may change the voltage used to charge the air particles as conditions associated with the air of a facility change over time.
