The condensation method is to directly introduce organic waste gas into a condenser, recover valuable organic matters through the actions and reactions of links such as adsorption, absorption, analysis, separation and the like, recover waste heat of the waste gas and purify the waste gas, so that the waste gas reaches the emission standard. However, the waste gas (containing water vapor and non-condensable gas) is cooled by using one-stage condensation, so that the waste heat cannot be well utilized and is directly discharged, and harmful components in the waste gas cannot be effectively removed, thereby causing air pollution; if one-section method is used for directly carrying out photocatalytic degradation after cooling, the photocatalytic system can be damaged due to high humidity of the discharged waste gas, the service life is influenced, and the operation cost is increased.
