Embodiment 1
[0022] Such as figure 2 As shown, the two dry granulation units 1 transport slag particles to the same waste heat recovery unit 7 through the chain bucket conveyor 6 respectively. The dry granulation unit 1 and the waste heat recovery unit 7 are located at the same level, and the chain bucket conveyor 6. Convey horizontally and then upwardly, with an inclination angle of 20 to 30 degrees; the cold material bin 2 is equipped with low-temperature slag particles with a large particle size, and the high-temperature slag is mixed with the high-temperature slag at the outlet of the granulation unit 1 through the flow adjustment device 3 at a suitable flow rate. The slag particles impact and mix with each other, and fall into the hopper 5 of the chain bucket conveyor 6; after the waste heat recovery unit 7, a screening device 8 is used to separate the slag particles with a diameter of 3 to 5 mm, and the slag particles with a diameter of 3 to 5 mm are separated through the cold materi...
Embodiment 2
[0024] Such as image 3 As shown, the dry granulation unit 1 and the waste heat recovery unit 7 are located on the same horizontal plane, connected by the chain bucket conveyor 6, and the chain bucket conveyor 6 is first conveyed horizontally and then inclined upward, with an inclination angle of 20-30 degrees; cold material The bin 2 is equipped with steel balls, which fall into the hopper 5 of the chain bucket conveyor 6 at a suitable flow rate through the flow regulating device 3, and spread on the bottom of the hopper 5; when the temperature measuring device 4 measures the temperature of the slag particles 11 higher than the set When the value is fixed, each hopper is filled with multi-layer steel balls 12, and when the measured temperature is lower than the set value, the amount of steel balls loaded in the hopper is reduced; the mixture of steel balls and slag particles recovers heat through the waste heat recovery unit 7 Finally, when the temperature drops below 150°C, ...
