<p>PURPOSE:To contrive the recovery of an organic solvent with efficiency by admixing the mist of the organic solvent with a static agent to form a mist to be charged with electricity, charging such mist by a charging device to form a charged mist and recovering the same by a collection electrode. CONSTITUTION:The mist or gas of organic solvent such as flon and trichloroethane in an addition chamber 9 is sprayed with a static agent 12 (e.g., dibutyl phthalate) from a spray nozzle 10 so as to form the mist to be charged. Such mist 22 is charged by a charging device 16 to form a charged mist, which is recovered by contact with a collection electrode 17. Since active carbon is not used largely for this collection, the troublesome replacement thereof can be reduced considerably, leading to an efficient recovery of the organic solvent. Also, the recovered mist can be reused by being separated into the static agent and the organic solvent.</p> |
