Example Embodiment
[0042] Example 1
[0043] The structure of the system for recovering copper slag waste heat and directly reducing iron and raising iron in this embodiment is as follows figure 1 As shown, it consists of a slag granulation and waste heat recovery device, a copper slag carbon-containing pellet preparation device and a direct reduction device;
[0044] The slag granulation and waste heat recovery device includes a slag granulation component and a waste heat recovery component. The slag granulation component is composed of a slag slag tank 1, a centrifugal granulation device 2, a blower 5, and a slag particle collection device 4. The slag particle collection device 4 is a funnel-shaped container with a wide upper and a narrow bottom. The centrifugal granulation device 2 capable of rotating at a high speed is arranged inside the slag particle collection device 4, and the slag slag tank 1 extends from above. Inside the slag particle collection device 4, and the discharge port of the slag...
