一种等离子空气净化消毒器的性能研究

STUDY ON PERFORMANCE OF DISINFECTION OF A PLASMA AIR PURIFIER

目的观察等离子体空气净化消毒器的消毒与净化效果及其相关性能。方法采用仪器采样法，对该等离子体空气净化消毒器进行模拟现场和现场消毒试验。结果该消毒器所发生的等离子体密度为1．7×109／cm3。该消毒器在两种新风模式下运行1h，对密闭气雾室内空气中人工污染的白色葡萄球菌平均消除率达到99．95％。同样条件下运行1h，对365m。的密闭空间内空气中自然菌平均消除率分别为97．68％和96．51％。该消毒器运行1h，出风口正前方1m处空气中臭氧浓度为0．02—0．11mg／m3。结论该等离子体空气净化消毒器具有良好的消毒、净化作用。

Objective To observe disinfection and purification effects and associated performance of a plasma air purifi- er. Methods Instrument sampling method was used to carry out the field test and simulated field test of the plasma air pu- rifier disinfeetor. Results The density of the plasma generated by the equipped plasma generator of this disinfector was 1.7 × 109/cm3. The disinfector running for lh at two new wind patterns, on a closed artificial indoor air pollution aerosol white Staphylococcus, the average elimination rate was 99. 95%. Run under the same conditions lh,within 365 m3 of natu- ral bacteria in the air in confined spaces mean elimination rates were 97. 68% and 96. 51% respectively. The disinfector running for 1 h, at 1 m in front of the outlet, the concentration of ozone in the air was 0.0 - 0. 11 mg/m3. Conclusions The plasma air purifying disinfector has good disinfection and purification effect.
