Abstract
An integrated drying process and device for dry granulated slag and sludge are provided. The process comprises: 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. With the present invention, cooperative treatment of slag cooling, granulation and sludge drying are obtained.
