Abstract
The invention includes 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 i micron in size and a concentration of at least 1,000,000,000,000 per cubic cm.
Claims20
A method for formation of a mist consisting of ultra-fine droplets, said method comprising the steps of:
- a) providing a partition, at least a region thereof being gas permeable, said region is defined by a first and by a second surface
- b) moistening one surface of the region by a liquid to form a film thereon, while leaving the second surface of the region substantially dry and
- c) establishing a stream of gas directed from the dry surface to the moistened surface of the region, wherein said gas stream is capable to pass the gas-permeable region covered by the film.
An apparatus for formation of a mist consisting of ultra-fine droplets, said apparatus comprises
- a) a partition, at least a region thereof being gas-permeable, said region is defined by a first and a second surface
- b) a moistening means for moistening one surface of the region by a liquid phase
- c) a means for establishing a gas stream directed from the dry surface of the region to the moistened surface thereof wherein said gas stream is capable to pass the gas-permeable region moistened by the liquid.
