Description

一种正负离子复合滤芯
技术领域
本发明涉及空气净化技术领域,具体的说是一种正负离子活性碳纤维复合滤芯。
背景技术
空气污染中主要成分包括固体颗粒物及游离的小分子, 如二氧化硫、二氧化氮、硫化氢,以及甲醛等挥发性有机物。活性炭吸附及离子发生器对这些污染物有较好的清除效果。活性炭为的多孔材料,其中的毛细管具有很大表面积,可通过范德华力吸附空气中的污染物。同时,孔径细小的毛细管也可捕捉空气中的颗粒物。
离子发生器分为负离子发生器或正负离子发生器;负离子发生器通过高电压在金属或碳材料的尖锐末端放电,对周边空气及其所含污染物离子化,以沉降或静电吸附的方式降低空气中污染物的浓度;正负离子发生器是在产生正离子和负离子在空气中进行正负电荷中和的瞬间释放巨大能量,从而导致其周围细菌结构的改变和能量的转移,从而导致细菌死亡,实现杀菌的作用。而且能达到高效分解甲醛/苯系物/氨等TVOC及其他气态有机挥发物的作用,从而消除异味。
目前活性炭和负离子以及正负离子净化空气通常是分别应用或简单叠加,而且现有的负离子发生器以及正负离子发生器大多只通过少量的碳纤维束实现尖端放电;现有设备的各项功能部件集成度低,电离效率低,负离子只能在局部空间释放,活性炭只能实现非极性吸附及颗粒捕捉。
发明内容
针对上述存在的技术问题,本发明的目的是:提出了一种正负离子复合滤芯。
本发明的技术解决方案是这样实现的:一种正负离子复合滤芯,包含离子发生器和至少一组滤芯单元;所述滤芯单元包含第一导电层、第二导电层和多孔隔离层,多孔隔离层设置在第一导电层和第二导电层之间;所述离子发生器为负离子发生器或正负离子发生器;所述离子发生器为负离子发生器时,第一导电层与负离子发生器的负离子输出端连接,第二导电层接地,并且第一导电层的内侧面上设置有多个导电毛细尖端;所述离子发生器为正负离子发生器时,第一导电层与正负离子发生器的负离子输出端连接,第二导电层与正负离子发生器的正离子输出端连接,并且第一导电层和第二导电层的内侧面上均设置有多个导电毛细尖端。
优选的,所述第一导电层和第二导电层为活性炭、分子筛、或附着光触媒的金属材料。
优选的,所述的导电毛细尖端密集且均匀分布。
优选的,所述第一导电层和第二导电层均为由活性炭纤维编织而成的活性炭板,导电毛细尖端为在编织过程中形成的碳纤维毛细尖端。
由于上述技术方案的运用,本发明与现有技术相比具有下列优点:
本发明的正负离子复合滤芯,将导电材料与正负离子净化功能集成为高效的复合滤芯;导电材料本身具有常规的吸附、捕捉污染物的功能,并通过离子发生器给予了其静电吸附的功能,且滤芯结构提高了正负离子释放空间,显著地提高净化效率。
附图说明
下面结合附图对本发明技术方案作进一步说明:
附图1为本发明所述的一种正负离子复合滤芯的一种实施方式示意图;
附图2为本发明所述的一种正负离子复合滤芯的另一种实施方式示意图。
具体实施方式
下面结合附图来说明本发明。
实施例1
如附图1所示,本发明所述的一种正负离子复合滤芯,包含离子发生器1和至少一组滤芯单元,每组滤芯单元均包含第一导电层2、第二导电层3和多孔隔离层4;所述第一导电层为活性炭、分子筛、或附着光触媒的金属材料中的一种,第二导电层为活性炭、分子筛、或附着光触媒的金属材料中的一种,第一导电层与第二导电层可以为同种材料,也可以为不同材料组合使用,其中分子筛可通过喷金来提高导电性;在本实施例中,第一导电层2和第二导电层3均为由活性炭纤维编织而成的活性炭板,并在第一导电层2的内侧形成密集且均匀分布的碳纤维毛细尖端,形成类似毛毡的结构;所述多孔隔离层4设置在第一导电层2和第二导电层3之间,多孔隔离层4为开放式的多孔材料;所述离子发生器1为负离子发生器,第一导电层2与负离子发生器的负离子输出端连接,使第一导电层2带负电,第二导电层3接地。
实施例2
如附图2所示,本发明所述的一种正负离子复合滤芯,包含离子发生器1和至少一组滤芯单元,每组滤芯单元均包含第一导电层2、第二导电层3和多孔隔离层4;所述第一导电层为活性炭、分子筛、或附着光触媒的金属材料中的一种,第二导电层为活性炭、分子筛、或附着光触媒的金属材料中的一种,第一导电层与第二导电层可以为同种材料,也可以为不同材料组合使用,其中分子筛可通过喷金来提高导电性;在本实施例中,第一导电层2和第二导电层3均为由活性炭纤维编织而成的活性炭板,并在第一导电层2和第二导电层3的内侧均形成密集且均匀分布的碳纤维毛细尖端,形成类似毛毡的结构;所述多孔隔离层4设置在第一导电层2和第二导电层3之间,多孔隔离层4为开放式的多孔材料;所述离子发生器1为正负离子发生器;第一导电层2与正负离子发生器的负离子输出端连接,使第一导电层2带负电,第二导电层3与正负离子发生器的正离子输出端连接,使第二导电层3带正电。
在实际使用过程中,携带污染物的空气穿过滤芯,第一导电层2在常规吸附、捕捉污染物基础上,其碳纤维毛细尖端同时起到电离空气的作用;第一导电层2与第二导电层3之间形成高电位差,电离后的空气及带电污染物通过第二导电层3时,污染物因带有静电,被有效地吸附在带正电或中性的第二导电层3上,而第二导电层3同时也起到常规吸附、捕捉污染物的作用。由于第一导电层2在相对第二导电层3的一侧上的碳纤维毛细尖端数量巨大且分布均匀,产生的负离子不仅数量多而且与通过的空气充分接触,显著地提高了空气净化效率。
上述实施例只为说明本发明的技术构思及特点,其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施,并不能以此限制本发明的保护范围,凡根据本发明精神实质所作的等效变化或修饰,都应涵盖在本发明的保护范围内。
