Description

一种用于净化塔的过滤膜
技术领域
本发明涉及净化塔领域，特别是涉及一种用于净化塔的过滤膜。
背景技术
随着我国经济的发展，在能源消费中带来的环境污染也越来越严重。其中大气烟尘、酸雨、温室效应和臭氧层的破坏已成为危害人民生存的四大杀手。燃煤烟气所含的烟尘、二氧化硫、氮氧化物等有害物质是造成大气污染、酸雨和温室效应的主要根源。我国南方及西南部地区相当一大片地域频繁发生酸雨和酸雾的灾害。我国燃煤取得的能量达到能源总量的75%以上，而且这种能源结构在近年不会改变。与此同时燃煤烟气中排放的二氧化硫和氮氧化物占全国总排放量的90%。因此在我国对燃煤烟气进行脱硫脱硝是刻不容缓的任务。
烟气在脱硫脱硝的同时也要进行除尘处理，然而，目前的烟气的除尘处理对超细粉尘颗粒的过滤效率低，以至于影响到了脱硝脱硫效果。
发明内容
本发明主要解决的技术问题是提供一种用于净化塔的过滤膜，对超细粉尘颗粒的过滤效率高，除尘过滤的十分充分，能够改善脱硝脱硫的效果。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种用于净化塔的过滤膜，包括：支撑基础膜层、第一尼龙56纳米蛛网纤维膜层、碳管增强聚丙烯腈/尼龙6复合纤维膜层、第二尼龙56纳米蛛网纤维膜层和醚酰亚胺-二氧化硅纳米纤维膜层，所述的支撑基础膜层的内表面由内往外依次设置有所述的第一尼龙56纳米蛛网纤维膜层、所述的碳管增强聚丙烯腈/尼龙6复合纤维膜层、所述的第二尼龙56纳米蛛网纤维膜层和所述的醚酰亚胺-二氧化硅纳米纤维膜层。
在本发明一个较佳实施例中，所述的第一尼龙56纳米蛛网纤维膜层的厚度与所述的第二尼龙56纳米蛛网纤维膜层的厚度相同。
在本发明一个较佳实施例中，所述的支撑基础膜层的厚度大于第一尼龙56纳米蛛网纤维膜层的厚度。
在本发明一个较佳实施例中，所述的支撑基础膜层的厚度大于醚酰亚胺-二氧化硅纳米纤维膜层的厚度。
本发明的有益效果是：本发明对超细粉尘颗粒的过滤效率高，除尘过滤的十分充分，能够改善脱硝脱硫的效果。
