Mobile aeraulic isolation device () with variable geometry multi-block air diffusion chamber (), comprising at least two mobile plenums () to protect a sensitive area such as a bed () against contaminating airborne aerosols. It comprises an air diffusion chamber () formed of at least two rigid plenums () mechanically connected together so as to be mobile relative to one another, and having a lower air diffusing surface () substantially planar and porous to air. Relative movement means () for mobile plenums () enable their positioning in relation to one another in at least two distinct relative positions. The device () comprises physical decontamination means () for moving air passing through it, air pressurising means (), aeraulic connection () and air circulation means, and a mobile supporting chassis (). The device) is characteristic in that it comprises complementary means for absolute movement () of the group of two rigid plenums () relative to chassis (). So that its two plenums () are both mobile, both relative to one another and relative to chassis (). Device) forms a mobile protective isolation device for immunosuppressed persons.

Mobile aeraulic isolation device against airborne contamination with variable geometry air diffuser

Ionic emission electrostatic device () for depositing on the surface (sp) of a multitude of aerosol particles (p, p, . . . , pn) within a fluid (F), a quasi-homogeneous quantity of ions (i). This electrostatic device () is constituted by a conductive discharge corona electrode (EC) and a noncorona conductive receptor electrode (ER). The pseudo-planar active face (SA) of its receptor electrode (ER) is covered by a plurality of craters with sharp edges, in a closed pseudo circle, exhibiting on their end edges (Ai) a section of minimum bend radius, and enclosing the orifices (O, O, . . . , On) and terminating towards the outside of the active face (SA). The craters are distributed quasi-uniformly on the active face (SA), in its two geometric directions. The surface flow of ions (i) originating from the corona electrode (EC) and in the direction of the active face of the receptor electrode (ER) has an increased homogeneity.

The invention concerns a volume generator ( ) of chaotic electrostatic field (E), locally amplified, to subject a fluid (U) loaded with aerosol parties (P, p) to the action of an electrostatic field (E) highly variable in amplitude and orientation locally. This generator ( ) includes: an induced electrostatic module ( ), consisting of a porous dielectric material (md), two porous electrodes with electrostatic induction ( ), an electrical current source ( ), and a device for boosting the fluid. The electrostatic module ( ) consists of a three-dimensional grid system (Rxyz) having at least locally three-dimensional periodicity (or pseudo-periodicity) in at least three directions. Each grid of the system consists of an externally convex and internally concave elementary cell recessed in its center for including a compact elementary empty cellular volume (V ), that is with transverse dimensions (dx , dy , dz ) of the same order of magnitude in the three directions. Preferably, it consists of a plurality of physically and electrically interconnected fins in the form of a dodecahedral array. The generator ( ) is useful for filtering air and in chemistry.
