Abstract:

According to the principle of atomizing corona discharge, a cooking fume purifier was made, and the volt-ampere characteristic curve of atomization condition and non-atomization condition, purification efficiency and discharge current were studied. The results showed that the discharge current of atomizing corona discharge was higher than the non atomizing corona discharge current, either positive or negative corona discharge; it was not conducive to the purification of earthed negative corona discharge cooking fume purification weather the flow too large or too small; cooking fume purifier efficiency were decreased with the increase of wind speed under both condition; the efficiency and the discharge current of atomizing corona discharge cooking fume purifier was almost unchanged with the increase of application time, while both of them decrease under the non-atomizing corona.

摘要： 根据接地极雾化电晕放电的原理制造了一台油烟净化器,对雾化条件和非雾化条件下的伏-安特性曲线、油烟中颗粒物的净化效率和放电电流进行了研究。结果表明,无论是正电晕放电,还是负电晕放电,接地极雾化电晕放电的放电电流都大于非雾化电晕放电电流;流量过大或过小都不利于接地极雾化负电晕放电对油烟的净化;两种情况下的净化效率都随着风速的增加而降低;雾化电晕放电油烟净化器的净化效率和放电电流几乎不随工作时间发生变化,而非雾化条件下二者均随着工作时间的增加而逐渐减小。
