由于深部矿井热害问题的日益严重,地面集中矿井降温系统得到越来越多的应用;高低压力转换装置(Pressure Exchange Device,PED)由于其技术优势及节能效果显著,得到了越来越多的重视。针对PED现场应用技术进行研究,实现了PED代替高低压换热器。实际运行表明,末端的降温幅度和PED的温度跃升均达到了预期目标,验证了系统的降温效果和节能效果。
Due to the increasingly serious thermal damage in deep mines, more and more applications are being made to ground cooling system in centralized mines. Because of its technical advantages and energy-saving effects, PED has been used more and more Pay attention. PED field application technology for research, to achieve PED instead of high and low pressure heat exchanger. The actual operation shows that both the temperature drop at the end and the temperature rise of the PED meet the expected target, and the cooling effect and the energy saving effect of the system are verified.
