The invention discloses a heat recovery module and a blast-furnace slag heat recovery device composed of the same. The heat recovery module comprises an auger delivery heat exchange device. A water quenching chamber is arranged on the auger delivery heat exchange device. A furnace slag inlet and a superheated steam outlet are formed in the upper portion of the water quenching chamber. The bottom of the water quenching chamber communicates with an inlet of the auger delivery heat exchange device. The auger delivery heat exchange device is connected with a power device. Spray devices are further arranged in the water quenching chamber. Collected furnace slag can pass through the heat recovery module, a medium in the heat recovery module and the furnace slag can exchange energy, the medium absorbing the energy can drive other executing mechanisms, the cooled furnace slag can be directly discharged out, the purposes of saving energy, reducing consumption and lowering the production cost are achieved, and the heat recovery rate of the device can reach 70% or over.
