Abstract: An object of the present invention is to provide an electric dust collector with its dust collecting performance being improved for collecting dust-like particles contained in a gas, whereas the increase in size thereof is being suppressed. An electric dust collector 10 distributes a gas G that has flown into a distribution chamber 90 to a plurality of charging flow paths 58 in a casing 12 thereof, causes the distributed gas to flow from insides of the charging flow paths 58 into internal flow paths 28 through mesh filters 30 that are formed as parts of the dust collecting electrodes 16 and that have large surface areas per unit volume. Then, the gas G is discharged to a central chamber 33 through internal outlets 32. Subsequently, the flow of the gas G is controlled to be discharged to the outside through a gas outlet 24.

Abstract: An air purification reactor is described that has a variety of improvements. In one aspect, the air purification reactor includes an ionizer (or plasma chamber), an electrostatic filter, a photocatalyst, and a UV light source that is distinct from the ionizer. The ionizer is arranged to introduce ions into a gaseous fluid stream passing through the air purification device. The electrostatic filter is located downstream of the ionizer and is arranged to electrostatically filter particles from the fluid stream. The UV light source is positioned to subject the photocatalyst to ultraviolet light and may be arranged upstream, downstream, or intermediate the electrostatic filter. With this arrangement, the ultraviolet light that impinges on the photocatalyst causes a photocatalytic oxidative reaction to occur at the photocatalyst that is capable of reducing volatile organic compounds carried in the fluid stream. In other (separate) aspects, the reactor includes an absorber or an oxidation catalyst. Generally, the various aspects of the invention may be used separately or in combination with one another.

Abstract: Disclosed is a dust collector (30) that is disposed in an air passageway (15) to which water droplets (21a) are supplied, and that includes a dust collecting electrode portion (31b) which electrically attracts dust charged in the air. The dust collecting electrode portion (31b) is made of a plate-like member having a mesh-like structure with a plurality of pores, thereby reducing an interfacial tension between the water droplets (21a) adhering on the surface of the dust collecting electrode portion (31b) and the dust collecting electrode portion (31b). Thus, water droplets are prevented from increasing in size on the surface of a dust collecting electrode, and a decrease in the dust collection capability due to adhesion of dust or the like is reduced.

Abstract: A vertical electrostatic coalescer comprises a first and second electrode surface and a horizontally disposed foraminous surface. The first electrode surface and horizontally disposed foraminous surface are at ground potential. The first and second electrode surfaces share the same planar orientation relative to the central longitudinal axis of the vessel. The unique arrangement of the vessel and opposing pairs of first and second electrode surfaces provides for a substantially uniform voltage field around a perimeter of the vessel and an effective voltage field for coalescence within a center of the vessel. A circular-shaped distributor pipe or a distributor housing serves to absorb momentum of the incoming emulsion stream and distribute the stream into an interior of the vessel.
