【摘要】：研发基于超细纤维的滤料是控制PM2.5的主要技术方向之一.采用国家标准建议的实验装置,对新型超细海岛纤维滤料的过滤性能进行综合研究,得出了滤料的过滤效率、残余阻力、清灰周期等参数,并与常规针刺毡滤料和覆膜滤料对比.结果表明:海岛纤维滤料对PM2.5的计数效率为94.9%,远高于常规针刺毡滤料,与覆膜滤料相当;动态过滤过程的残余阻力低于覆膜滤料,残余阻力上升缓慢,清灰周期更长,有利于延长滤料的寿命,节约成本.
[Abstract]:Based on the research of superfine fiber filter is one of the main direction of technology control PM2.5. The device adopts the recommendations of national standards, made a comprehensive study on the filtration performance of the new island superfine fiber filter, the filter filtration efficiency, residual resistance, cleaning cycle and other parameters, and with the conventional needle felt and membrane filter media. The results of comparison show that: the efficiency of counting the PM2.5 island fiber filter was 94.9%, far higher than that of conventional needle felt, and a membrane filter material; residual resistance dynamic filtration process is lower than that of the membrane filter, the residual resistance rises slowly, the cleaning cycle is longer, to prolong the service life of the filter material, save the cost.
