SALT WATER SPRAY SYSTEMS FOR CLOUD BRIGHTENING DROPLETS AND NANO-PARTICLE GENERATION

摘要

A system and a method for producing solid nano-particles of a material by dispersing very small droplets of liquid in which the material is dissolved. The nano-particles being particularly useful for geoengineering for increasing cloud reflectivity. The system includes: a. pump for supplying the liquid; and b a plurality of orifices included in at least one sprayer. The liquid upon being supplied to said sprayer forming droplets after flowing through the sprayer's orifices. The sprayer is selected from a group consisting of: a. domed sprayers; b. cusped cone sprayers; and c. Taylor cone sprayers (132). The method includes the steps of: a. both pressurizing and heating the liquid so the liquid is in a supercritical state wherein the liquid becomes like a dense gas and the surface tension approaches zero; and b dispersing the pressurized and heated liquid in the supercritical state through an orifice.
