The utility model provides a quick emptying structure of a quenching system, and belongs to the field of pyrolysis gas quenching equipment. The quick emptying structure comprises a quencher (1), a gasoline fractionator (3) and a diesel fuel stripper (4), wherein a pyrolysis gas is cooled by the quencher (1) and enters the gasoline fractionator (3), a top outlet of the gasoline fractionator (3) is communicated with a water-cooling tower, the middle of the gasoline fractionator (3) is communicated with an inlet of the diesel fuel stripper (4) through a pipeline, and a bottom outlet of the gasoline fractionator (3) is connected with a quenching oil circular processing device. The quick emptying structure is characterized in that a steam blowing pipeline (2) is connected to an inlet of the gasoline fractionator (3), the quenching oil circular processing device is connected with a plurality of temporary emptying pipelines (16), and the lower ends of the temporary emptying pipelines (16) are connected to a temporar
