Electrohydrodynamic spraying means
First Claim
1. Electrohydrodynamic spray device comprising at least one duct at an outlet of which a biased liquid can be sprayed, wherein it comprises means at least at the outlet of the duct which spray, in air and at atmospheric pressure, a liquid whose surface tension is greater than 0.055 N/m while generating a continuous discharge regime, wherein the means comprise, at least at the outlet, an external diameter value of the duct less than a limiting value Dmax which satisfies the equation:

Abstract
The invention concerns electrohydrodynamic spraying means enabling electrohydrodynamic spraying, in the air and at atmospheric pressure, of liquids with high surface tension such as water. The means are characterised in that they comprise at least a liquid dispensing conduit (1) whereof the dimensions of the external diameter and of the internal diameter, at the liquid exit point, correspond to an appropriate ratio. Said means can be advantageously used for depolluting aerosol effluents, or transformable into aerosols.
