摘要

摘要: 针对后疫情时代下建筑室内净化问题,选取6种过滤单元(1号—G4夹碳布,2号—G4涤纶,3号—F7玻纤,4号—F7静电熔喷布,5号—G4涤纶+F7玻纤,6号—微静电荷电模块+G4涤纶),试验探究其PM_2.5净化性能。试验测试了不同过滤单元的一次过滤效率、PM_2.5净化效率、阻力、洁净空气量(CADR)与净化能效 (CEE)。结果表明:1)5号和6号的组合过滤单元可有效提高一次过滤效率和PM_2.5净化效率。2)额定风速下,2号过滤单元阻力最小,5号过滤单元的阻力最大。3)在最大风量工况下,4号过滤单元的CADR和CEE最大,2号过滤单元的CADR和CEE最小,分别约为4号过滤单元的7.13%与6.54%。6号过滤单元相比2号过滤单元的CADR和CEE分别提升约150%与247%,表明微静电荷电模块在不增加过滤单元阻力的情况下,能够提高一次过滤效率和PM_2.5净化效率,有效缩短相同工况下的净化时间。

Abstract: In response to the requirements of building indoor purification in the post-COVID-19 era, six kinds of different filter units were selected (No.1—G4 carbon cloth, No.2—G4 polyester, No.3—F7 glass fiber, No.4—F7 electrostatic melt blown cloth, No.5—G4 polyester+F7 glass fiber, No.6-micro static charge electric module+G4 Polyester), and the PM_2.5 purification performance of different filter units were analysed through experiments. The primary filtration efficiency, PM_2.5 purification efficiency, resistance, CADR and CEE of the different filter units were tested. The results showed that: 1) No.5 and No.6 composed filter unit could effectively improve the primary filtration efficiency of the filter unit and PM_2.5 purification efficiency. 2) At the rated wind speed, the resistance of the No.2 filter unit was the lowest, and the resistance of the No.5 filter unit was the highest. 3) In the maximum air volume condition, CADR and CEE of the No.2 filter unit was the smallest, and CADR and CEE of the No.4 filter unit was the largest. The CADR and CEE of No.2 filter unit was about 7.13% and 6.54% of that of No.4 filter unit, respectively. Compared with No.2 filter unit, CADR and CEE of No.6 filter unit was increased by approximately 150% and 247%, respectively. The micro static charge electric module could promote the primary filtration efficiency and the PM_2.5 purification efficiency, and shorten the purification time effectively without increasing the resistance.
