摘 要:一种能应用于小型装置或实验室调节湿度的超声波加湿器,它通过加湿振子激振产生直径几微米的均匀雾状水粒来加湿.在对该种加湿器的工作过程进行了分析后,根据质量平衡原理,推导出加湿器加湿的动态数学模型,并对一个具体的装置进行了动态性能仿真和实验分析.结果表明本文建立的动态数学模型仿真得出的阶跃响应时间常数,及在不同占空比下加湿器出口的相对湿度与实验结果比较接近,能较好地反应加湿器中的加湿过程;另外仿真和实验结果也表明该加湿装置能根据加湿器工作时间占空比的不同,在很宽的范围内控制出口的湿度.The ultrasonic humidifier can be used in small scaled equip or the laboratory to adjust the degree of humidity, its wetting part flap to produce several microns of diameter of fog from water surface to add humidity. After the work process of this kind of humidifier is analyzed, it's mathematics model is deduced, accord- ing to the equilibrium principle of quantity, and the ultrasonic humidifier's dynamic performance is theoretically emulated in the article and practically tested. It is shown that the characteristic time of step response of RH which is calculated by the mathematic dynamic model and the RH at the humidifier outlet under the duty ratio is different, all being close to the results of tests, and the model indicates the process of humidifying in this device correctly. The test results also show the outlet humidity can be controlled in long range in it by this sort of humidifier under its different duty ratio.
