摘要:

压缩空气储能被认为是最有发展前景的大规模储能技术之一,压缩机作为压缩空气储能系统的关键部件,对系统的整体性能有重要影响。压缩机进气过滤系统是压缩机的重要部件,过滤器作为其核心元件,可以有效避免空气中固体颗粒、液体水和油污等杂质对压缩机的安全稳定运行造成不良影响,获得了国内外学者的广泛关注。压缩机进气过滤系统的研究虽然取得了一定的进展,但是相关领域的文献综述方面却显得相对匮乏。本文通过归纳国内外学者对压缩机进气过滤系统的研究,依照过滤原理进行分类,总结了机械过滤、吸附过滤、静电过滤原理的研究进展,并归纳了过滤器的过滤性能评价指标以及优化方法,通过分析发现:相比于吸附式过滤器,机械式和静电式应用更广泛,具有过滤效率高、压降小等优势;进气过滤系统评价指标主要有过滤效率、压降、容尘量和抗湿性,滤材种类、过滤器结构和工况会影响过滤性能,且过滤性能之间会互相影响;通过采用过滤性能更好的纳米纤维复合滤材、优化滤芯和流道结构,可以对进气过滤系统进行优化。

Abstract:

Compressed air energy storage is considered the most promising technology for large-scale energy storage, and the compressor, as a key component of the system, significantly influences overall performance. The compressor's intake filtration system is critical because its filter effectively prevents impurities-such as solid particles, liquid water, and oil pollution, from compromising safe and stable operation, an issue that has attracted widespread attention from scholars domestically and internationally. Although progress has been achieved in compressor intake filtration systems, literature reviews in this area remain relatively scarce. This article reviews research by domestic and international scholars on compressor intake filtration systems, categorizing studies according to filtration principles, including mechanical, adsorption, and electrostatic methods, and examines evaluation indicators and optimization approaches for filter performance. The following conclusions are drawn: compared with adsorption filters, mechanical and electrostatic filters are more widely used and offer advantages such as high filtration efficiency and low pressure drop; the evaluation indicators of the intake filtration system primarily include filtration efficiency, pressure drop, dust holding capacity, and moisture resistance; filter material, filter structure, and operating conditions interact to affect filtration performance; and the intake filtration system can be optimized by employing nanofiber composite filter materials with enhanced performance and by refining the filter element and channel structure.

Key words: compressor, filtration efficiency, pressure drop, dust holding capacity
