中文摘要:
      通过复合纤维素纤维与碳纳米管(CNT),制备CNT/纤维素纸基导电过滤材料(以下简称导电滤材),采用外接静电源方式,提升导电滤材静电吸附效率。通过改变成形方式、优化导电滤材定量及CNT添加量,调控导电滤材对空气颗粒物(PM)的过滤性能,并研究施加静电电压与过滤性能的关系。结果表明,定量45 g/m2、CNT添加量50%(相对于导电滤材定量)的导电滤材CCP-50-45综合过滤性能最优;在导电滤材上负载高压静电后,静电负载滤材过滤效率的提升与CNT添加量呈线性关系;负载静电电压达15 kV时,静电负载滤材CCP-50-45-e对PM0.3的过滤效率最高达88.29%,相比未负载高压静电时提升了20.51个百分点,且压降基本保持不变,仅30 Pa。
Abstract:
      This study prepared cellulose-based conductive filtration materials (hereinafter referred to as conductive filter materials) by compositing cellulose fibers and carbon nanotubes (CNT), and connected the external static power supply to enhance the electrostatic adsorption efficiency of the conductive filter materials. The filtration performance for air particulate matter of the conductive filter material was controlled by changing the forming method, and regulating the basis weight of the conductive filter material and the CNT addition amount. The relationship between the applied electrostatic voltage and the filtration performance was further studied. The results showed that when the basis weight was 45 g/m2 and the CNT addition amount was 50% (relative to basis weight of conductive filter material), the conductive filter material CCP-50-45 showed the best overall filtration performance. After loading the conductive filter materials with high-voltage static electricity, the filtration efficiency enhancement of filter materials loaded electricity was linearly related to the CNT addition amount. The filtration efficiency of filter materials loaded electricity CCP-50-45-e for PM0.3 was increased by 20.51 percentage points to 88.29% when the electrostatic voltage reached to 15 kV, and the pressure drop was kept unchanged with only 30 Pa.
