Abstract

Disclosed in the present invention are a slag hollow micro-bead preparation nozzle and a preparation method therefor, belonging to the technical field of metallurgical slag comprehensive utilization. The preparation nozzle comprises a nozzle body. A spraying end of the nozzle body is provided with gas nozzles used for spraying high-pressure gas and mist nozzles used for spraying cooling liquid drops. The mist nozzles and the gas nozzles are arranged in an array at intervals. The preparation method comprises: S1, melting blast furnace slag into a liquid state; S2, pouring the liquid blast furnace slag into a flow groove, and enabling the liquid blast furnace slag to flow along the flow groove to form a molten slag flow; S3, opening the nozzle body, synchronously spraying using the mist nozzles and the gas nozzles, so as to scatter the molten slag flow and blow the molten slag flow to a micro-bead collection chamber to obtain hollow micro-beads. The high-pressure gas can scatter the slag flow to form slag flow liquid drops, and the cooling liquid drops hit the slag flow liquid drops to enable same to be rapidly cooled and cured on the surface in contact with the cooling liquid drops. Under surface tension and viscosity, the slag flow liquid drops rapidly wrap the cooling liquid drops, the cooling liquid drops absorb heat and rapidly evaporate in the wrapping process, and then the hollow micro-beads are formed.
