摘要:

高温含尘废气的排放是造成环境污染的主要原因之一,纤维基空气过滤材料具有比表面积大、结构可控等一系列优点,在空气过滤领域备受关注。但普通纤维基空气过滤材料存在耐高温性能差的问题,为便于相关人员更好了解纤维基耐高温空气过滤材料的研究现状,本文对近年来纤维基耐高温非织造空气过滤材料的研究进展进行了综述。重点介绍了纤维基耐高温非织造空气过滤材料所用原料(有机纤维原料、无机纤维原料等),制备工艺(针刺、水刺、熔喷、静电纺、离心纺和气流纺等)及其功能化改性(脱硫、脱硝、脱VOCs等)应用。对耐高温非织造空气过滤材料制备和应用过程中存在的缺点进行了讨论,指出未来发展应以开发新材料、改进制备工艺和功能化改性为重点方向;以期为耐高温非织造空气过滤材料的研究提供一定参考,拓展纤维基耐高温空气过滤材料应用范围。

Abstract:

The hot flue gas from the industry is one of the main factors that cause air pollution. Therefore, the purification of hot flue gas is important for the environment and humankind. The fiber-based air filters have attracted much attention in the field of air purification due to its larger specific surface area and higher porosity. However, most fiber materials cannot withstand such high temperatures. In view of this, this paper reviewed the development of thermally stable fiber-based air filters in recent years. The main topics were focused on the raw materials (organic fibers, inorganic fibers) which can be used in the preparation of thermally stable air filters, preparation technologies (needle punching, spun lace, melt-blown, electrospinning, centrifugal spinning, air jet spinning, etc.) and multifunctional modification (denitration, desulfuration, and VOCs removal, etc.) of thermally stable fiber-based air filters. The shortcomings of thermally stable fiber-based air filters were discussed from the preparation to application. The development of thermally stable fibers, preparation technologies and multi-functionalization would be the key points for thermally stable fiber-based air filters. It was expected that thermally stable fiber-based air filters would gain more applications in the future.

Key words: thermally stable air filter, nonwovens, preparation technology, nanofiber, functional modification
