ABSTRACT:
A metal vapor-trapping system wherein a gaseous mixture containing vapors of liquid metal is conducted from a tank to a first device, where the gas is cooled to trap most of the metal vapors contained therein by condensing said vapors into a liquid form; the gaseous mixture is further delivered to a second device, where the gas is cooled to a lower temperature than the solidifying point of said liquid metal to trap residual metal vapors in the solidified form; a gas free from said metal vapors is discharged from the second device; and a liquid metal obtained by being condensed from its vaporized form in the first device is automatically brought back to the tank by valve control.
