Abstract
Liquid compositions containing solid or semi-solid constituents are resolved by atomizing the liquid to droplets of approximately 0.5 to 6 microns diameter, projecting the droplets at speed of 600 feet per second to sonic velocities into an ambient air entrainment zone wherein the droplets lose water rapidly by evaporation within a short distance, e.g., 30 cm. from their point of ejection, and recovering solids and liquids from the entrainment zone. The entire process is conducted at ambient temperature in the absence of any added heat.
Claims12
Method for the rapid separation of a liquid composition which contains solid dissolved or suspended therein which comprises:
- (a) atomizing said composition to droplets substantially in the range of 0.5 to 6.0 microns in diameter;
- (b) projecting the atomized droplets in the form of a spray at a velocity of 600 feet per second to sonic velocities directly into a mass of relatively dry, ambient, unheated air maintained at substantially standard temperature in an entrainment zone;
- (c) separating dry solid particles from liquid evaporated from the droplets within a short distance of the point of projection into the entrainment zone;
- and
- (d) recovering separated solid particles from the entrainment zone.
