Definitions
- the present invention relates to an aerosol collector and a method of collecting an aerosol using the aerosol collector.
- Atmospheric fog is an important source of water whose collection is of major interest, especially in arid regions. The collection of atmospheric fog also allows its meteorological analysis.
- Atmospheric pollutants in the form of aerosols are also interesting to collect to purify the air, in particular it is interesting to capture pesticides during spreading on the periphery of the treated area or to capture the liquid from aerosols from the industry that are released into the atmosphere.
- an aerosol collector comprising at least one net comprising a plurality of spaced apart elongated liquid collector units, each collector unit comprising a collection space extending longitudinally along the collection unit and configured to collect liquid from the aerosol in the form of a liquid column extending into the collection space along the collection unit, the spaces collection having a transverse dimension less than the smallest distance in the transverse direction between the adjacent collecting units, the collection spaces having a transverse dimension less than or equal to 6 mm.
- the drops have a number-average diameter less than or equal to 500 ⁇ m, better still less than or equal to 100 ⁇ m, even better less than or equal to 50 ⁇ m, even better less than or equal to 10 ⁇ m.
- Liquid column means a continuous deposit of liquid along the corresponding collecting unit, formed by spreading the liquid of the aerosol along the collecting unit.
- Collection space means the space of the collection unit in which the liquid is collected in the form of a liquid column.
- transverse dimension it is necessary to understand the dimension in a plane perpendicular to the longitudinal axis of the collecting units and substantially parallel to the plane of extension of the net.
- Such an aerosol collector by liquid column allows the liquid of the aerosol to coalesce with the liquid column and to be continuously drained by gravity towards a reservoir, while presenting a large liquid collection surface and preserving a space requirement. minimum of collecting units, unlike individual drops obtained on single threads. This allows for better collection efficiency.
- the collecting units allow, by orienting the net so that the collecting units are at least partially vertical, that the liquid flows by gravity along the liquid columns, which facilitates the collection of the liquid.
- the collection spaces have a transverse dimension smaller than the smallest distance between the collection units makes it possible to ensure that the liquid columns will indeed form in the collection space of the collection units and not between the collection units of so as to leave spaces for the circulation of the aerosol between the collecting units.
- the fact that the aerosol is never completely prevented from circulating makes it possible to improve the mechanical resistance of the collector in the presence of flows having a high speed. This also makes it possible to facilitate the flow of the liquid at the level of the liquid columns by avoiding contact between several liquid columns and to prevent the mist from deviating from the net if it cannot circulate through the latter, which would prevent any liquid collection.
- liquid columns are formed on the collecting units allows better capture efficiency by playing the role of capturing film having a high affinity with the liquid to be captured in the collecting units.
- the transverse dimension of the collector units is less than or equal to 3 mm, better still less than or equal to 1 mm.
- the collector units of the net are all of the same transverse dimension.
- the collecting units can be of different transverse dimensions.

- Such solidity allows both an effective aerosol collection rate and good circulation of the aerosol between the collecting units. A lower solidity does not allow a sufficient number of collector units to efficiently collect the aerosol and a higher solidity generates interactions between adjacent collector units which decrease the collection efficiency.
- the collection spaces extend over the full height of the collection units.
- the collection spaces are configured to collect the liquid from the aerosol in the form of a liquid column over the entire height of the corresponding collection unit.
