Description

一种空气过滤装置 技术领域
本发明属于空气过滤设备领域，尤其涉及一种空气过滤装置 。
 背景技术
空气净化装置随着日益严重的空气污染已经越来越体现出其对于生活、医疗、生产等等方面的重要性，目前市场上比较流行的空气净化设备均使用平板过滤纸，需过滤空气通过过滤纸的拦截，起到了灰尘细菌等杂质与纯净空气相分离的作用，但目前广泛采用风道直接对平板过滤纸送风的方式，风速较大，对于平板过滤纸的直接压力过大，细菌和灰尘在高速撞击过滤纸时容易被挤压通过过滤纸，从而降低空气过滤后的质量，另外，平板是过滤纸的过风面积较小，在较小的过风面积情况下，如果为了提高空气过滤的效果，一般均采用增厚增密过滤纸的方式，然而这种方式致使风阻增大，出风量减少，空气净化效率降低，净化速度减慢。
