• the present invention is more particularly intended to generate technical aerosols for more intensive use.
• the system is directly set in motion by a wind turbine or when the energy source comes from a renewable energy such as solar energy, the invention is more specifically intended for permanent or semi-permanent use in a medium isolated, for example the oxygenation of water in lagooning installations or the spraying of salt water with a view to its desalination.
• the applications and examples given here are for illustrative purposes only and are not limiting or exclusive.
• nozzle atomization is to expel a liquid contained in a pressurized reservoir through a nozzle. At the passage of this nozzle there is spraying of the liquid and droplet formation whose flow and size depend on the upstream pressure, the shape of the nozzles and the method of pressurizing.
• the second method called rotating disk atomization, results from the natural or controlled fragmentation into drops of a liquid 0 from a rapidly rotating disk.
• the flow rate and the size of the drops depend mainly on the speed of rotation and the dimensions of the object in rotation.
• aerosol generators In the case of domestic applications or autonomous and portable industrial installations, the most commonly used devices are the aerosol generators, often called aerosol cans, consisting of a reservoir containing active liquid pressurized by a gas and atomized at through a nozzle.
• the gases used are either gases compressed under pressures of several bars (for example CO 2 ), or dissolved gases, or in some cases liquefied gases.
