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： A roller treatment process and a treatment device suitable for a total-amount steel slag treatment. The treatment process is: firstly, a slag tank (2) with the molten slag is tightly held by a slag tank tilting mechanism and moved to a slag inlet position, the slag tank (2) is tilted to pour the molten slag with good fluidity into a rotary roller device (5) through a feeding chute (51), so that a roller treatment is achieved; secondly, when the steel slag (3) without fluidity in the slag tank (2) cannot flow out, a slag removal machine (4) is used for pushing the high-viscosity slag or the solid slag into the roller device (5); and thirdly, the slag tank (2) is reversed by a large angle tilting to make the slag at the bottom of the tank drop into the roller device (5), so that the total-amount steel slag treatment of the same roller device (5) is achieved. The treatment device comprises a feeding system, the roller device (5), a particle slag conveying and storage system (7), a tail gas emission and purification system (6), a cooling water circulation system (8), a cold steel cleaning mechanism (10) and an electric control system (9); and the feeding system comprises the slag tank tilting mechanism (1), the slag tank (2), the molten slag (3) and the slag removal machine (4).
