Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] A liquid blast furnace slag granulation and multi-drum waste heat recovery system uses high-pressure gas to crush the blast furnace slag, and uses multi-stage series drums to cool down the slag particles in steps and recover waste heat.
[0023] The structure of this embodiment is as figure 1 As shown, it includes a three-stage series drum, an exhaust cotton collection system, and a waste heat recovery system, wherein the three-stage series drum includes a first-stage vaporization drum granulation bin 5, a second-stage vaporization drum storage bin 9, and a third-stage drum cooler 10; The discharge port of the vaporization drum granulation bin 5 communicates with the feed port of the secondary vaporization drum storage bin 9 through the feed pipe, and the discharge port of the secondary vaporization drum storage bin 9 communica...
