Description

一种高CADR的EMF过滤系统及空气净化设备 技术领域
本发明涉及空气净化技术领域，更具体地说，涉及一种高CADR的EMF过滤系统及空气净化设备。
 背景技术
现有的EMF结构通常由下至上并排设置的三部分组成：下放电网（负极），离子网（正极），上放电网（负极）；工作时，空气从下放电网进入依次穿过下放电网，离子网，上放电网，HEPA处于离子网和上放电网之间，并贴紧上放电网；在下放电网和离子网之间由正负极组成高压电网对空气放电，使得空气中的颗粒物带上电荷，然后穿过HEPA时被HEPA吸附；由于电荷及电场的相互作用，提高了HEPA的吸附效率，同时由于电荷不停的释放，使得收集在HEPA上的微生物表面收到电场力的作用，被拉扯破坏从而被杀死。
该结构方式对下放电网、离子网、上放电网、HEPA之间的位置和尺寸有严格的要求，需要的空间比较大，在产品设计时机器的空间利用率低，产品的风阻大，CADR值低，噪音高，能效偏低。
 技术问题
本发明要解决的技术问题在于，针对现有技术的上述缺陷，提供一种高CADR的EMF过滤系统，还提供了一种空气净化设备。
 技术解决方案
本发明解决其技术问题所采用的技术方案是：
