回答1:

  空气净化方式:
  1.滤网:单层或多层过滤,能明显降低空气中固态尘埃,但如需过滤较细小(5 Micro以下) 的悬浮粒子时,风阻较大。过滤装置使用一段时间后需要更换,无法再生。
  滤网也可与其他材料复合(如活性碳、沸石等)后达到去除异味或一般杀菌效果。主要以物理吸附方式处理空气中的异味,在短时间内能吸附一定的细菌和尘土及有害气体,价格低廉,但无选择吸附,对水的吸附率为45%,达到饱和状态需更换。无法再生利用。达到饱和后不但不能杀菌而且容易成为细菌的衍体。
  2.化学制剂:如空气清新剂(香水、香精、精油) ,其产品价格低廉,但也只能掩盖一些异味,而且在阳光作用下发生复杂的化学反应,成为新的污染源,根本无法消除有害气体。
  另外也有以中药制剂杀菌,其原理相同,杀菌能力及效率有限,多数仅为抑菌作用。
  化学制剂需依赖加温产生挥发作用,挥发物对皮肤病患者、孕妇、高血压及癫痫患者有影响。
  3.静电集尘:静电集尘是电荷异性相吸原理,利用外加高压而形成二个极性相反的电场,使烟尘粒子荷电后向集尘板移动而附著在集尘板上,而达到净化空气目的。缺点必须要定期清洗,否则其集尘效率将明显下降,且静电吸附装置因采用高压放电,毫无疑问地产生臭氧。臭氧具有很强的氧化性,当其遇到细菌、霉菌或其它有毒化学物质及臭味时产生氧化反应,氧化分解有毒物质及臭味,并能隔绝紫外线。

目前空气净化器主要有两种主流技术,一是吸附式,一般主要依靠活性炭等具有吸附性能的材料,来达到净化空气的作用;二是滤网式,吸入脏空气后,通过一些高科技过滤材料把空气中的污染物过滤掉。美国hoover空气净化器,就是采用HEPA过滤网及过滤技术, 能够有效阻隔99.97%、低至0.3微米微尘及花粉及有效消毒及杀菌。智能监测环境,滤网永久反复使用。

回答3:

应用最多还是HEPA滤网技术。

回答4:

现在市场上的空气净化器一般采用的技术有:活性炭技术、HEPA滤网技术、紫外线技术等等。

回答5:

空气净化器又称能够吸附、分解或转化各种空气污染物(一般包括PM2.5、粉尘、花粉、异味、甲醛之类的装修污染、细菌、过敏原等),有效提高空气清洁度的产品,主要应用于家用 、商用、工业、楼宇。

空气净化器中有多种不同的技术和介质,使它能够向用户提供清洁和安全的空气。常用的空气净化技术有:吸附技术、负(正)离子技术、催化技术、光触媒技术、超结构光矿化技术、HEPA高效过滤技术、静电集尘技术等;材料技术主要有:光触媒、活性炭、合成纤维、HEAP高效材料、负离子发生器等。现有的空气净化器多采为复合型,即同时采用了多种净化技术和材料介质。

但是Airgle将市场上现有的HEPA网进行优化升级,研发制成的cHEPA过滤网,对0.003微米的可吸入颗粒物去除率高达99.999%,有效去除空气中漂浮的粉尘、花粉、烟雾、PM2.5等。
