Embodiment 1
[0047] see Figure 1-6 As shown, this embodiment is a working principle and working process of a high-temperature slag and waste heat recovery treatment device:
[0048] For a high-temperature slag and waste heat recovery and processing device in the present invention, after the high-temperature slag is produced by circuit or converter smelting, in order to avoid heat waste, we send the slag into the material transfer box 101, and use the slag The high-temperature air directly emitted is passed into the smelting equipment again; at the same time, the high-temperature air also rapidly heats the water in the steam generating box 104 to generate water vapor, which is used in boiler rooms or other equipment; into the slag processing device 2, through the remaining heat, heat the cold fluid that needs to be exchanged in the tube heat pipe group; after the heat exchange is completed, it is cooled with the cooling liquid to become the final waste;
[0049] During the working process...
