The utility model relates to a condenser for an organic Rankine cycle power generation system. The condenser comprises a shell, a cooling water outlet, a cooling water inlet, gaseous work medium inlets, a liquid work medium outlet and cooling water pipe bundles, and further comprises a filter plate. At least two gaseous work medium inlets communicated with an evaporator work medium outlet of the power generation system are fixedly connected to the upward cylindrical face of the shell. A funnel-shaped liquid work medium accumulation cavity is formed in the lower side face of the shell. The inclination angle a formed when an inlet cavity wall of the liquid work medium accumulation cavity is inclined towards the upper end face of a liquid accumulation pipe ranges from four degrees to six degrees. The cooling water pipe bundles are evenly distributed in a cavity of the shell in the axial direction and communicated with inner cavities of seal plugs. The condenser has the advantages that gaseous work media are efficiently cooled, clean liquid organic work media are provided for the system, the second gaseous work medium inlet is formed, the system overpressure problem caused by heat source fluctuation is effectively prevented, the safe running of system is directly protected, and the service life of a turbine is directly prolonged.
