Description
技术领域technical field
本发明涉及空气净化技术领域，尤其涉及一种环保型多级空气净化设备。The invention relates to the technical field of air purification, in particular to an environment-friendly multi-stage air purification equipment.
背景技术Background technique
目前市场上的空气净化机多数仅具有简单的空气过滤功能，通过产生高压静电场来吸附空气中的尘埃，不仅结构复杂生产成本高，而且对于空气中所含的细菌、病毒及甲醛、苯等化学污染物并没有处理能力。少数空气净化机采用了在过滤的同时加入臭氧杀菌除化学污染物的方法，但是这又导致了净化后的空气中臭氧含量超标造成了二次污染。At present, most of the air purifiers on the market only have a simple air filtration function. They absorb dust in the air by generating a high-voltage electrostatic field. Chemical pollutants have no treatment capacity. A small number of air purifiers have adopted the method of adding ozone to sterilize and remove chemical pollutants while filtering, but this has caused the ozone content in the purified air to exceed the standard and cause secondary pollution.
