The invention discloses an efficient recovery device for waste heat of molten calcium carbide. The efficient recovery device comprises a shell internally provided with a cavity, a container located in the shell and used for containing the calcium carbide in the molten state, a heat absorbing mechanism located in the shell and used for absorbing heat in air, a medium replacing mechanism used for replacing a heat exchange medium in the heat absorbing mechanism, and a circulating mechanism used for driving air in the shell to be circulated. By the adoption of the efficient recovery device of the structure, the container containing the calcium carbide in the molten state, the heat absorbing mechanism used for absorbing the heat in the air, the medium replacing mechanism and the circulating mechanism are arranged in the shell so that heat released during curing and cooling of the calcium carbide in the molten state can be recovered, and different media are adopted in the heat absorbing mechanism for achieving the
