METHOD AND SYSTEM FOR FLUID STREAM CHEMICAL COMPOUNDS COLLECTION, DEPOSITION AND SEPARATION

摘要

A system adapted for chemical compounds collection, deposition and separation in a fluid stream, also adapted to be inserted in a closed volume, characterized in thatit comprises: - a stack of layers (21,....2n; 41,....4n) with a number of window openings (S;), allowing the fluid stream to pass through, neighboring layers forming an angle 0 < a < 90°, the angle being variable and controlled, the distance between neighboring layers being variable and controlled, so as to control the velocity of the flow of fluid stream inside the system; - a number of spreading apertures (31,...3m; 51,... 5m) in between the layers, and adapted to spray liquid chemical solution inside the closed volume, so as to create a thin film of liquid chemical solution on the surfaces of the layers and lateral walls of the closed volume; - a system for generating droplets of chemical solution upstream of said stack, to be mixed in said fluid stream; - particles of the chemical compounds being collected by impaction with the droplets, and by diffusion on the thin film, and counter flowing with the chemical solution.
