Abstract

PURPOSE: To reduce the concentration of polychlorinated biphenyl (PCB) gas, by introducing the gas into a liquid tank containing a liquid such as oil, solvent, water, etc. and furnished with a cooling means, thereby dissolving the gas in the liquid or precipitating the liquefied gas to the bottom of the tank.
CONSTITUTION: A definite amount of liquid such as oil (e.g. kerosene), solvent, water, etc., is charged into a liquid tank 1 furnished with a cooling means through a liquid charging pipe 9. PCB gas is introduced into the tank 1 through a feed pipe 2 by the action of suction pump 3, and bubbled in the liquid through a bubbling pipe 4. The PCB gas is dissolved in the liquid, or when the liquid is water, precipitated as a semifluid material to the bottom of the tank, and the small amount of the evaporated PCB gas is treated with a gas-liquid separator 5. The dissolved PCB solution or the precipitated PCB is recovered from the recovery holes 6, 7 and 8, and sent to the next treatment step.
EFFECT: The concentration of PCB gas generated by the disposal of the PCB-containing electrical parts, can be reduced and the subsequent treatments are facilitated.
