Abstract:
An apparatus, which collects particulate matter contained in a gas flowing through a flow path formed in a cylindrical shape having an outer surface and an inner surface, includes: an outer shell that forms the outer surface of the flow path; a ground electrode that forms the inner surface of the flow path; a filter layer that is arranged between the outer shell and the ground electrode; and a discharge electrode that generates, when a voltage is applied, an ion wind inducing a secondary flow toward the ground electrode in a direction transverse to the flow path. The secondary flow passes through the ground electrode and the filter layer having a predetermined aperture ratio.

Abstract:
The invention concerns an electrostatic ionic emission device for depositing on the surface of a plurality of particles aerosols within a fluid, a quasi-homogeneous amount of ions. The device comprises a discharge corona conductive electrode, and a non-corona conductive receptor electrode. The pseudo-planar active surface of its receptor electrode is covered with a quasi-uniformly distributed plurality of sharp-edged craters, enclosed by a pseudo-circle, having on their end edges a section with minimum bend radius, and enclosing orifices, emerging outwards of the active surface. Said sharp-edged craters are quasi-uniformly distributed on the active surface, in both its geometrical directions. The surface flow of ions derived from the corona electrode towards the active surface of the receptor electrode has increased homogeneity. Preferably, the receptor electrode is produced by means of an array of metal fins.

Abstract:
An inner electrode formed inside a dielectric body and a surface electrode formed on a surface of the dielectric body. The surface electrode is formed in a grid pattern with pointed parts formed inside the grid section. Each pointed part is in the shape of a triangle whose vertices are two arbitrary points on a side of the grid section and an arbitrary point inside the grid section, or a quadrangle whose vertices are a crossing of grid lines, an arbitrary point near a straight line connecting crossings of grid lines in the diagonal positions, and two arbitrary points on sides of the grid section. An ion generating element is formed which can generate positive ions and negative ions. The ion generator can be used in an air conditioning apparatus, cleaner or refrigerator.

The invention concerns an electrostatic ionic emission device (1) for depositing on the surface (sp) of a plurality of particles (p1, p2, pn) aerosols within a fluid (F), a quasi-homogeneous amount of ions (Iq). The device (1) comprises a discharge corona conductive electrode (EC), and a non-corona conductive receptor electrode (ER). The pseudo-planar active surface (SA) of its receptor electrode (ER) is covered with a quasi-uniformly distributed plurality of sharp-edged craters, enclosed by a pseudo-circle, having on their end edges (Ai) a section with minimum bend radius, and enclosing orifices (O1, O2, On), emerging outwards of the active surface (SA). Said sharp-edged craters are quasi-uniformly distributed on the active surface (SA), in both its geometrical directions. The surface flow of ions (Iq) derived from the corona electrode (EC) towards the active surface of the receptor electrode (ER) has increased homogeneity. Preferably, the receptor electrode (ER) is produced by means of an array (R′xyz) of metal fins.

An air cleaning device includes a bulb-shaped casing provided at one end with an attached portion to be attached an attaching portion and connected to a commercial power source and at the other end with an outlet, an ozone generator accommodated in the casing and an air supply portion formed in the casing for supplying air into the ozone generator. The ozone generator includes a needle first electrode having a distal end directed to the outlet and a cylindrical second electrode concentric with the first and second electrodes. Application of high voltage between the first and second electrodes induces electrical discharge therebetween, generates negative ions and ozone and releases a stream of air containing the generated negative ions and ozone from the first electrode to the second electrode and outlet.
