Abstract

Direct outdoor air depollution represents an interesting path for preventing indirect disease. In the present work, a simple and efficient PMs trapping media based on the use of an oil-coated structured polymer media was developed for passive trapping of various PMs, ranging from coarse (PM₁₀), to fine (PM_2.5) and ultra-fine (PM₁) dimension in outdoor environment. The device can be easily regenerated by a simple washing with a mixture of water and detergent followed by a new oil coating cycle. The total PM loading mass of the passive trap and the recovered PMs are analyzed through different techniques and confirm the great efficiency of such filter to trap various PMs when exposed to a high traffic road. The spent filter can be regenerated through a simple washing step and can be repeatedly re-used with similar PM loading mass. The high and long-lasting total PM loading mass were also supported by numerical simulations based on computational fluid dynamics, also used to propose an optimization implementation of such system for future deployment at scale.

可清洗的涂油结构支架，用于被动式室外颗粒物捕集

直接消除室外空气污染是预防间接疾病的有效途径。本研究开发了一种简单高效的可吸入颗粒物捕集介质，该介质基于油涂层结构聚合物介质，可被动捕集室外环境中的各种可吸入颗粒物，从粗颗粒物（PM10）到细颗粒物（PM2.5）和超细颗粒物（PM1）。只需用水和洗涤剂的混合物进行简单清洗，然后进行新的涂油循环，就能轻松地再生该装置。通过不同的技术分析了被动式捕集器的可吸入颗粒物总质量和回收的可吸入颗粒物，结果表明，当暴露在交通繁忙的道路上时，这种过滤器捕集各种可吸入颗粒物的效率非常高。用过的过滤器可以通过简单的清洗步骤进行再生，并可重复使用，其可吸入颗粒物的质量相近。基于计算流体动力学的数值模拟也证明了这种过滤器具有较高和持久的可吸入颗粒物总装载量，并提出了这种系统的优化实施方案，以便将来大规模部署。
