PURPOSE: An apparatus for recovering volatile organic compounds is provided to recover volatile organic compounds contained in exhaust gas at a high efficiency by sequentially changing density and temperature of volatile organic compounds containing gas contained in the exhaust gas. CONSTITUTION: The apparatus comprises first condensation part in which first cooler(11) is installed at an inflow part(13) through which hazardous gas containing volatile organic compound is introduced, blocking net(12) is spaced apart from the lower part of the first cooler, and the hazardous gas containing volatile organic compounds is condensed by reciprocal bonding force between the first cooler and blocking net; second condensation part which is positioned at the lower part of the first condensation part, and at which second cooler(21) is installed to condense residual volatile organic compounds passing through the first condensation part; third condensation part which is positioned at the lower part of the second condensation part, at the upper part of which evaporator(31) is installed, and in which third cooler(32) is installed at the lower part of the evaporator to condense the residual volatile organic compounds passing through the third cooler; and an oil-water separator(60) into which the condensed volatile organic compounds passing through the second condensation part and third condensation part are flown so that water and organic compounds contained in the condensed volatile organic compounds are separated and recovered.
