摘要： A method and apparatus for acoustically enhancing cooling of molten liquid. In one embodiment, a cement plant has a mill in which raw materials are mixed and ground into a powder, a kiln in which the powdered raw material undergoes a calcining process and is converted into a molten liquid known as clinker, a cooler for cooling and solidifying the clinker, and a finishing mill for grinding and mixing the clinker with gypsum and/or other raw materials. The clinker cooler has a transport mechanism for transporting clinker from an inlet end to an outlet end and a plurality of fans, located below the transport mechanism, for blowing air up through the transport mechanism and into the bottom surface of the clinker bed. The clinker cooler has one or more horns positioned on the roof of the cooler for emitting acoustic energy into the cooler. A controller controls activation of each horn independently, such that each horn may be operated continuously or intermittently. Emission of acoustic energy into the cooling chamber of the clinker cooler creates turbulence in the air and molten liquid flowing in the cooler, thereby enhancing the cooling process. The increased turbulence and energy within the cooler assists breaking up of the solidified clinker, thereby enhancing contact between the clinker surface and air.
