摘要

水泵是制造、采矿、农业、石油和天然气以及化学加工等不同工业部门的基本功能。如图 1 所示,全球泵的能耗约为 15%,而在采矿业中,泵的能耗最高可达平均能耗的 24%。与其他工业应用相比,采矿业的用水具有一些显著特点。大多数大型矿山都位于干旱或半干旱地区,这些地区水资源匮乏,农业和城镇等竞争性用户较少。矿山本身可能就是该行业最大的用水户。因此,为了应对缺水问题,有必要将水运到很远的地方,以便为矿山供水。一般来说,矿山在多个流程中都需要用水,其中一些流程至关重要,因此抽水对于确保该行业的持续运行至关重要。另一方面,就地理位置而言,由于矿山可能在多风地区和/或太阳能辐照丰富的地区(如智利和澳大利亚的铜矿或南非的铬铁矿)运营,因此使用可再生能源为水泵供水是一个很有吸引力的选择。在本文中,我们将探讨采矿业对泵的要求、利用可再生能源实现电气化的可能性、局限性以及这一相关工业领域的前景。

Renewable Source-Based Water Pumping Electrification in Mines: Current technologies and future trends
Water pumping is an essential function in diverse industrial sectors, including manufacturing, mining, agriculture, oil and gas, and chemical processing. The global energy consumption of pumps is approximately 15%, and in the particular case of the mining industry, pumps can represent up to a 24% of the average consumption of energy, as shown in Figure 1. The use of water in the mining industry has some distinctive features compared to other industrial applications. Most of the large mines are located in arid or semiarid regions where water is scarce and there are few competing users, such as agriculture and towns. A mine itself could be the largest water user in the sector. Therefore, to cope with water scarcity, it could be necessary to transport the water large distances to supply a mine. In general, a mine requires water in several processes, some of them critical, then, pumping is crucial to ensure the continuous operation of the industry. On the other hand, regarding the geographical location, as mines could operate in windy regions and/or regions rich in solar irradiation, e.g., copper mines in Chile and Australia, or chromite mines in South Africa, the use of renewable energies to supply pumps is an attractive option. In this article, we explore pumping requirements in the mining industry, its possibilities for electrification based on renewables sources, the limitations, and the prospections of this relevant industrial sector.

期刊介绍: ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
