The utility model relates to a low-boiling point working medium circulating system for recovering blast-furnace cinder heat and belongs to the field of the mechanical equipment. The low-boiling point working medium circulating system for recovering the blast-furnace cinder heat is provided with a low-boiling point working medium heat conduction device, a low-boiling point working medium heat convection device and a low-boiling point working medium heat radiation device on the basis of facilities such as a cinder channel, a punching box and the like in existing water quenching treatment system for blast-furnace cinder; the low-boiling point working medium exchanges heat with hot water at the bottom of the punching box, water vapor at the top of the punching box and high temperature cinder in the cinder channel in three ways comprising heat conduction, heat convection and heat radiation, so that low-boiling point working medium steam is formed to push the low-boiling point working medium generating set to gener
