摘要:
In the plasma reactor of the present invention, streamer discharge is caused in a wide region so as to increase a plasma generation region without complicating the architecture of the plasma reactor and increasing the cost. In the plasma reactor of the invention, a needle-shaped first electrode and a plate-shaped second electrode are disposed to oppose and to be perpendicular to each other, and the first electrode has a pointed portion as the end thereof on the side of the second electrode and the pointed portion has a point angle θ not less than 30 degrees and not more than 90 degrees, and preferably not less than 60 degrees and not more than 90 degrees.
摘要:
Each protrusion (42) of a first electrode (40) is formed to have a long plate-like shape extending across a plurality of grid holes (46) of the first electrode (40). Each grid hole (56) of a second electrode (50) is formed to have an elongate shape extending to conform to each corresponding one of the protrusions (42) of the first electrode (40). Protrusions (52) of the second electrode (50) are arranged in the longitudinal direction at end portions (54a) on the long sides of the respective grid holes (56) of the second electrode (50), so as to conform to the grid holes (46) of the first electrode (40).

A dust collector includes a charging part (12) for charging dust with electricity and a dust collecting part (30). Each of a dust collecting electrode (40) and a high-voltage electrode (50) that constitute the dust collecting part (30) includes: a base (41, 51) with a rectangular grid structure having a large number of vent holes (46, 56) formed therein; and projections (42, 52) extending into the vent holes (56, 46) of the opposed electrode (50, 40). The dust collector collects dust by generating an electric field between the dust collecting electrode (40) and the high-voltage electrode (50).
摘要:
An electric power supply of a discharge device which generates a streamer discharge is provided with a discharge control part. By virtue of the discharge control part, the discharge electric power of the discharge device is increased or decreased depending on the treatment amount of a component to be treated in an air purification device.
摘要:
Disclosed is an air purification device including a discharge part for discharging electricity in air. Low-profiling of the air purification device is accomplished while maintaining the discharge capability of the discharge part. In an ionization part (30) for electrically charging airborne dust particles, an insulating medium (60) is disposed between an ionization wire (31) serving as a discharge base end and an earth electrode (33). As a result of such arrangement, electrical discharge from the ionization wire (31) to the earth electrode (33) is obstructed while on the other hand corona discharge from the ionization wire (31) to a first electrode plate (32) is maintained, whereby the distance between the ionization wire (31) and the earth electrode (33) can be made narrow.
摘要:
The present invention relates to a charging device having a charge section (20) for charging a floating particle in an air to be handled, and an air handling device (an air cleaning device) having the charging device. The charge section (20) is constituted by a first charge section (20a) adopting an impact charging technique and a second charge section (20b) adopting a diffusion charging technique. With this structure, charging and collection of dust can be accomplished only in the casing of the device, and therefore, an increase in size of the device can be avoided.
摘要:
An air handling device (10) includes an air flow path (13) in which a charge section (20) for charging dust in an air to be handled, and a precipitator (30) for collecting the charged dust are placed. The charge section (20) includes a discharge electrode (25) and a counter electrode (26) to perform diffusion charging. A diffusion space (13a) is provided at a location between the charge section (20) and the precipitator (30).
