一种移动式通风装置及其应用

摘要

This paper introduces a mobile ventilation device without construction or installation, which can be used in conventional indoor ventilation and indoor emergency ventilation for short time and high concentration pollutants as well. The movable ventilation device can be conveniently pushed into a room needing ventilation. This kind of device is safe and efficient with low cost, and it has a wide application range, too. The treatment effect of surface source pollution is significantly better than the fixed type ventilation cabinet. Ammonia and six sulfur hexafluoride gas test results have shown that the deviceˊs average ventilation efficiency is over 95%.%本介绍了一种无需施工和安装的移动式通风装置，可用于常规室内通风及短时间高浓度污染物泄漏情况下的室内应急通风。移动式通风装置可以随时方便地推放到任意需要通风换气的房间，成本低廉、安全高效、用途广泛。该装置对地面污染源的处理效果显著优于固定式通风橱，氨水及六氟化硫气体试验结果表明，该装置的平均换气效率高于95%。
