摘要： An integrated drying process and device for dry granulated slag and sludge. The process comprises the following steps: 1) slag ball mixing and soaking: high-temperature slag and steel balls are fully mixed and exchange heat therebetween, the high-temperature slag is cooled because the heat thereof is quickly absorbed by the steel balls and is crushed to form granular slag, and the temperature of the steel balls rises because the steel balls absorb the heat of the high-temperature slag; and 2) sludge drying: the high-temperature steel balls are conveyed to a sludge drying device to be mixed with injected sludge, the sludge is dried, the steel balls are separated from the sludge when the water content of the sludge reaches a set value, and the steel balls and the sludge are separately discharged. In the present invention, high-temperature slag waste heat is used for heating steel balls, and sludge is dried by means of the heated steel balls, thus achieving the cooperative treatment of slag cooling, granulation and sludge drying, solving two difficult problems of slag cooling and sludge drying, and greatly increasing the waste heat recycling rate of high-temperature slag.

摘要： Disclosed are a blast furnace slag granulation and waste heat recovery and utilization device and method, the device comprising an aerosol granulation nozzle assembly, a deflector (7), a cyclone separator (8) and a waste heat recovery device. The aerosol granulation nozzle assembly comprises a slag flow controller (2), a compressed air flow control valve (3), a water volume control valve (4) and an aerosol spray gun (5). Mixed heat exchange between medium temperature gas and high temperature granular slag (6) and the solidification of the high temperature granular slag are achieved in the deflector, and the medium and high temperature gas and high temperature granular slag after heat exchange are introduced into the cyclone separator. The cyclone separator completes the separation of the medium and high temperature gas and high temperature granular slag, and transports the medium and high temperature gas and the high temperature granular slag to the waste heat recovery device. The present invention completes the granulation of blast furnace slag, and organically couples slag sensible heat recovery with sludge drying, high-temperature steam preparation, power generation and low-temperature hot water preparation, thereby recovering the waste heat of medium temperature gas and high temperature particles in the process of slag granulation and improving the efficiency of waste heat recovery and utilization.
