室内空气净化器净化方法
Purification method of indoor air purifier
空气中颗粒物去除技术主要有机械过滤、吸附、静电除尘、负离子和等离子体法及静电驻极过滤等。
Particulate removal technology in the air mainly includes mechanical filtration, adsorption, electrostatic precipitation, anion and plasma method and electrostatic electret filtration.
机械过滤一般主要通过以下3种方式捕获微粒：直接拦截，惯性碰撞，布朗扩散机理，其对细小颗粒物收集效果好但风阻大，为了获得高的净化效率，滤芯需要致密并定期更换。
Mechanical filtration is generally used to capture particles in the following 3 ways: direct interception, inertia collision, and Brown diffusion mechanism, which have good collection effect on fine particles but large wind resistance. In order to obtain high purification efficiency, the filter core needs to be compact and replaced regularly.
吸附是利用材料的大表面积及多孔结构捕获颗粒污染物，很容易堵塞，用于气体污染物去除效果更显著；
Adsorption is the use of materials with large surface area and porous structure to capture particulate pollutants, it is easy to plug, for gas pollutants removal effect is more significant;
静电除尘是利用高压静电场使气体电离从而使尘粒带电吸附到电极上的收尘方法，其风阻虽小但对较大颗粒和纤维捕集效果差，会引起放电，且清洗麻烦费时，易产生臭氧，形成二次污染。
Electrostatic precipitator (ESP) is a method of collecting dust on the electrode by ionization of high voltage electrostatic field so that the dust particles are charged to the electrode. Although the wind resistance is small but the effect is poor on the larger particles and fiber, it will cause the discharge, and it is easy to produce ozone and form two times of pollution when cleaning trouble and wasting time.
负离子和等离子体法去除室内颗粒污染物的工作原理类似，都是通过使空气中的颗粒物带电，聚结形成较大颗粒而沉降，但颗粒物实际上并未移除，只是附着于附近的表面上，易导致再次扬尘。
The working principle of negative ions and plasma removal of indoor particulate pollutants is similar, all of which are settled by forming particles in the air and forming larger particles, but the particles are not actually removed, only attached to the nearby surface, which can easily lead to dust.
静电驻极过滤以3M（ [2]  ）“高效静电空气过滤网”为代例,采用突破性携带永久静电滤材，有效阻隔空气中大于0.1微米的颗粒污染物，如粉尘、毛屑、花粉、细菌等，同时超低阻抗确保空调稳定运行及制冷效果。此外，深度容尘设计确保使用寿命更长。在家庭及车载空调(如上汽、大众、通用等知名品牌畅销车型)以及一些商用建筑领域(如鸟巢、北京饭店、首都机场三期)得到广泛应用。
Electrostatic electret filter, with 3M ([2]) "high efficient electrostatic air filter" as an example, uses a breakthrough permanent electrostatic filter to effectively block particulate pollutants, such as dust, wool, pollen, bacteria, etc. in the air, such as dust, hairs, pollen, bacteria and so on. At the same time, the ultra low impedance ensures the stable operation and cooling effect of the air conditioner. In addition, the deep dust design ensures a longer life. It has been widely used in family and vehicle air conditioning (such as the best selling models of famous brands such as SAIC, Volkswagen and general-purpose), as well as in some commercial building fields (such as the bird's nest, Beijing Hotel, capital airport, three phases).
传统的标准过滤介质能非常有效地去除10微米以上的颗粒物。当颗粒物的粒径除至5微米，2微米甚至亚微米的范围时，高效的机械式过滤系统就会变得比较昂贵，且风阻会显著增加。通过静电驻极材料过滤,能以较低的能源消耗达到很高的捕获效率，同时兼具静电除尘低风阻的优点，但无需外接上万伏的电压，故不会产生臭氧,且由于其组成为聚丙烯材质，很方便抛弃处理。
The traditional standard filtration media can remove particles more than 10 microns very effectively. When the particle size is 5 microns, 2 micrometers or even sub microns, the efficient mechanical filtration system will become more expensive and the wind resistance will increase significantly. Through electrostatic electret material filtering, it can achieve high capture efficiency with lower energy consumption, and also has the advantages of electrostatic precipitator and low wind resistance, but it does not need to connect the voltage of tens of thousands of volts. Therefore, it will not produce ozone, and because its composition is made of polypropylene, it is very convenient to abandon the treatment.
