NOUFERROUS METALLURGICAL EQUIPMENT

Under the current “carbon peak and carbon neutrality” policy in China, mine waste heat recovery and reuse is one of the pathways for mines to transform to green and low carbon mines. Based on this background, in view of the current situation of ventilation in an alpine mine, this paper designs a ventilation waste heat recovery scheme to solve its shaft collar antifreeze issue in cold seasons, and analyzes the waste heat recovery effect by acquiring 6-month operating data of the system. The results show that the overall operation status of each waste heat recovery unit is relatively stable, and the effect of waste heat recovery is remarkable. Compared with the electric heating scheme, it greatly reduces the energy consumption and the operating costs, and has a huge potential for application promotion.
