An air dust removal method, comprising the following steps: 1) using an ionization dust removal electric field to adsorb particulate matters in intake air; and 2) using the ionization dust removal electric field to charge an intake air electret element. The method can effectively remove dust in air, the dust removal ability is better, and the dust removal efficiency is higher.

An example of a system for use in collecting fluid from a gas stream includes one or more collection panels and a frame for arranging the panel(s). Each of the collection panel(s) may comprise an emitter electrode assembly member, comprising one or more emitter electrodes, physically attached to an electrically insulated from a fluid collection member comprising one or more collection electrodes. The frame may be sized and shaped to be disposed near a gas outlet or a duct. An example of a method for collecting fluid from a gas stream includes providing the collection panel(s) disposed in a path of the gas stream; providing the gas stream; generating and maintaining a voltage at the one or more emitter electrodes of each of the collection panel(s); and collecting an amount of the fluid from the gas stream with the one or more collection panels.

An air filtration system having a housing. The housing has an inlet, a frame unit, a filter unit, and an outlet. A fan is positioned in the air filtration system or not, and pulls or pushes air into the inlet, and through the outlet, and has the air pass through the filter unit. The filter unit has a first and a second expanded metal metallic plate. The first plate has a first plurality of apertures, and the second plate a second plurality of apertures. Each plate has a coated layer of a dielectric conducting and antimicrobial agent polymer material. The frame unit secures the first expanded metal metallic plate at a first position in the housing, the second expanded metal metallic plate at a second position in the housing, and ensures, when the first and second expanded metal metallic plates are securely positioned in the housing, that the first expanded metal metallic plate is adjacent to the second expanded metal metallic plate and wherein a portion of the first expanded metal metallic plate contacts or is within 20 millimeters from the second expanded metal metallic plate and each aperture of the second plurality of apertures misaligns with an aperture of the first plurality of apertures.

An air dust removal system (101) includes a dust removal system inlet (1011), a dust removal system outlet, and an electric field apparatus (1014). The electric field apparatus (1014) has an electric field apparatus inlet, an electric field apparatus outlet, a dust removal electric field cathode (10142), and a dust removal electric field anode (10141); the dust removal electric field cathode (10142) and the dust removal electric field anode (10141) are used for generating an ionization dust removal electric field. When dust is collected in the ionization dust removal electric field, the electric field apparatus (1014) detects an electric field current. The air dust removal system (101) can effectively remove particulate matters in air.

An air filtration system has a housing. The housing has an inlet, a filter unit, an outlet, and a fan that pulls air into the inlet, pushes the air through the outlet, and has the air pass through the filter unit. The filter unit has a first metallic plate, a second metallic plate and a frame unit. The first and second metallic plate (a) is coated with a dielectric conducting and antimicrobial agent polymer layer, and (b) respectively has a first and second plurality of apertures. The second apertures do not align with the first apertures when the first and second plates are properly positioned in the housing. The frame unit ensures plates are properly positioned in the housing.

An ionization chamber is provided with a series of parallel plates spaced from each other and with holes passing therethrough. Alternating plates have either a highest high voltage or a lower high voltage provided thereto, such as through a DC transformer coupled to an electric power source. Holes in alternating plates are preferably offset so that airflow through the plates occurs along curving pathways. The plates are sufficiently highly charged to cause carbon dioxide to be ionized and for carbon ions to become trapped within wells defining lowest regions of electric charge within an electric field inside the ionization chamber. Fans control airflow through the ionization chamber. A dehumidifier is provided upstream of the ionization chamber to reduce moisture content within the incoming gas. After the carbon has collected within the wells, harvesting of the carbon ions as carbon nano particle powder can occur within a carbon cache.
