Abstract
The invention concerns a method and apparatus (100) for producing mist of a liquid phase having very fine and mono-dispersed droplets. The method is realized by an apparatus (100) including a partition (101), defined by a first side surface (107) and a second side surface (113). The first side surface (107) is wetted by a liquid phase to form a film thereon, while the second side surface (113) is substantially dry. A gas stream is directed through the partition (101) from the dry side (113) to the wetted side (107) thereby forming a mist having droplets of less than 1 micron in size and a concentration of at least 1,000,000,000,000 per cubic cm.

A method for formation of a mist consisting of ultra-fine droplets, said method comprising the steps of:
- a) providing a partition, made of a rigid material, at least a region thereof being gas permeable, said region is defined by a first and by a second surface and by a bulk portion confined therebetween,
- b) moistening the first surface of the region by a liquid to form a film of the liquid, said film coating the first surface of the region, while leaving dry the second surface of the region and the bulk portion thereof,
- c) establishing a stream of gas directed from the second surface to the first surface of the region, wherein said gas stream is capable to pass the bulk portion of the gas-permeable region and to convert the film covering the first surface into a mist consisting of plurality of discrete droplets, said droplets emerging from the first surface of the gas permeable region.
An apparatus for formation of a mist consisting of ultra-fine droplets, said apparatus comprises:
- a) a partition made of a rigid meterial, at least a region thereof being gas-permeable, said region is defined by a first and by a second surface and by a bulk portion confined therebetween,
- b) a liquid discharge device capable of moistening the first surface of the gas-permeable region by a liquid to form a film of the liquid on the first surface
- c) a means for establishing a gas stream directed from the second surface of the gas-permeable region to the first surface thereof wherein said gas stream is capable to pass the bulk portion of the gas-permeable region and to convert the film covering the first surface into a mist consisting of plurality of discrete droplets which emerge from the first surface of the gas-permeable region.
