空气净化器原理及技术 Principle and technology of air purifier 空气净化器又称“空气清洁器”、空气清新机，是指能够吸附、分解或转化各种空气污染物（一般包括粉尘、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，目前以清除室内空气污染的家用和商用空气净化器为主。 Air purifier is also called "air cleaner" machine, fresh air, refers to the adsorption and decomposition or transformation of various air pollutants (including dust, pollen, peculiar smell, formaldehyde, decoration pollution, such as bacteria, allergens, etc.), effectively increase the air cleanliness of product, at present to remove indoor air pollution in the residential and commercial air purifier. 空气净化器是用来净化室内空气的小型家电产品，主要解决由于装修或者其他原因导致的室内空气污染问题。由于室内空气中污染物的释放有持久性和不确定性的特点，因此使用空气净化器净化室内空气是国际公认的改善室内空气质量的方法。 Air purifier is a small household appliance that purifies indoor air, the main solution is because of decorate or other cause of indoor air pollution problem. Due to the release of pollutants in indoor air with persistence, and the characteristics of uncertainty, so using air purifier purify indoor air is internationally recognized as the way to improve indoor air quality. 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：低温非对称等离子体空气净化技术、吸附技术、负离子技术、负氧离子技术、分子络合技术、光触媒技术、HEPA高效过滤技术、静电集尘技术、活性氧技术等；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。目前国内市场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。 Air purifiers have a variety of different technologies and mediators that allow them to provide clean and safe air to users. Commonly used in air purification technology are: asymmetric plasma air cleaning technology at low temperature, adsorption, negative ion, negative oxygen ion technology, molecular complexation, photocatalytic technology, HEPA efficient filtration, electrostatic dust collection technology, active oxygen technology, etc.; Material technology mainly includes: photocatalyst, active carbon, synthetic fiber, HEAP high efficiency material, negative ion generator, etc. At present, the existing domestic market air purifier is compound, namely, the use of various purification technology and material medium.
