| 摘要 |
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 (I~q). 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 (I~q) derived from the corona electrode (EC) towards the active surface of t he receptor electrode (ER) has increased homogeneity. Preferably, the receptor electrode (ER) is produced by means of an array (R'xyz) of metal fins.</SDOA B>
