室内、车载空气净化器用滤网发展现状及趋势

Development status and future trend of the filters for indoor and vehicle air purifiers

室内和车内空气污染对人体影响非常大,是威胁人类健康的“隐形杀手”。空气净化器是控制空气污染物的一种有效手段,而空气净化器滤网是空气净化器的关键部件,其对污染物的净化效率和复杂污染条件下的稳定性有很大影响。本文首先介绍了室内、车内主要空气污染物的来源,明确了需要治理的主要目标。然后根据净化滤网的工作原理介绍了市场上主流室内、车载空气净化器滤网,比较了初、中效滤网,高效过滤网(HEPA),传统型活性炭滤网,负载型活性炭滤网,静电集尘滤网,贵金属催化式滤网,非贵金属催化式滤网,光触媒滤网,等离子滤网和多功能滤网各自的优劣势。最后提出了空气净化器滤网今后的发展趋势,分别是HEPA滤网、锰基室温催化材料、低温等离子体材料、多功能滤网和多技术协同净化滤网。

Indoor and vehicle air pollution has a great impact on human health and is often labeled as a“hidden killer”.Air purification is an effective means to control air pollutants,and the filter in air purifier is the key part,which has a great impact on the purification efficiency and the stability of air purifier under complex pollution conditions.This review starts with the introduction of the sources of the main indoor and in-car air pollutants,and defines the main problems to treat.Then,according to the working principles of purification filters,it introduces the main indoor and vehicle air purifier filters in the market,and compares the advantages and disadvantages of primary and medium efficiency filter,high efficiency filter,traditional activated carbon filter,load activated carbon filter,electrostatic dust collection filter,precious metal catalytic filter,non-precious metal catalytic filter,photocatalyst filter,plasma filter and multi-function filter.Finally,the development trend of the filter in the future is put forward,including HEPA filter,manganese-based room temperature catalytic material,low temperature plasma material,multi-functional filter and multi-technology collaborative purification filter.
