在空气净化系统末端分布装置中采用了阻漏层。“阻漏”概念的提出是从另一条思路解决了末端高效过滤器送风装置的渗漏和空气分布问题。运用“阻漏层”这一技术措施，使末端气流分布装置的过滤、均流和堵漏的三个功能“解偶”，以极其经济、方便、有效地阻漏，十分灵活地分布或变更气流，这是一种新概念的气流分布装置。 A barrier layer is used in the air distribution system at the end of the air purification system. The concept of “blockage” is to solve the problem of leakage and air distribution of the end high efficiency filter blowing device from another train of thought. The use of “barrier layer” is a technical measure to “uncouple” the three functions of filtration, current sharing and plugging of the end airflow distribution device, so as to be extremely economical, convenient and effective in blocking and distributing or changing with great flexibility Airflow, which is a new concept of airflow distribution device.
