厨房排风扇对室内SO_2净化效果测定

Determination of the Cleaning Efficiency of Indoor SO_2 by Kitchen Ventilator

本文对单元式住宅燃煤厨房排风扇净化效果进行测定.结果表明,开炉后未开排风扇室内SO_2可超过大气卫生标准2.5～16.6倍.开炉后开排风扇室内 SO_2浓度可明显减低(P<0.01).排风扇净化效果最高可达96%.

This paper descries the determination of the cleaning efficiency of SO_2 by kitchen ventilator in the domestic used coal. The results showed that when the stove was opened, the indoor SO_2 concentration rapidly increased. It was 2.5～16. 6 times that of the Air Sanitary Standard. When the stove was opened with the kitchen ventilator turning on,the indoor SO_2 concentration was lower than with/out ventilator turning on. (P<0. 01). The highest cleaning efficiency of the kitchen ventilator was 96%.
