A method for recovering organic waste gas produced through dry process overlaying and after finishing for synthetic leather comprises following steps: (1), waste gas discharged from an exhaust port of a drying oven is introduced into the high-temperature side of a heat pipe type hot wind heat exchange device, the temperature of the waste gas is reduced, and the absorbing capacity of an absorbent is improved; (2), the waste gas discharged from the heat pipe type hot wind heat exchange device is introduced into a first absorption tower adopting a water-soluble solvent with high boiling point and high vapor pressure as an absorption liquid, and a water-insoluble solvent in the waste gas is removed; (3), the waste gas discharged from the first absorption tower is introduced into a second absorption tower adopting water as an absorbent, the water-soluble solvent in the waste gas is removed, and the treated gas is discharged. According to the method, by the aid of the two stages of absorption towers adopting the absorption liquids with different properties, the weak polar solvent in the organic waste gas is removed by the first absorption tower, the water-soluble organic solvent in the waste gas is removed by the second absorption tower, the waste gas treatment effect is good, and the organic solvent can be recovered and sufficiently utilized.
