摘要
脉冲电磁场(PEF)技术由于工艺简洁、高效、环保等特点受到广泛的关注和研究。将其引入到PM_(2.5)的运动控制领域,分别测试了密闭空间内PM_(2.5)质量浓度分别为700μg/m^3、500μg/m^3、300μg/m^3时,通过参数为500 V、2 Hz的PEF处理8min的PM_(2.5)浓度变化。结果表明,经过短时间的PEF处理后,电脉冲磁场作用区域内的PM_(2.5)浓度显著降低,并形成宏观可观测的流体行为。这一发现有望为局部区域内的临时性空气质量管制提供一种新方法。
Pulsed electromagnetic field(PEF)technology has been extensively studied due to the simple process,high efficiency,environmental protection and other characteristics.Through this technology to influence PM 2.5 movement,it was measured that the concentration changes of PM 2.5 in different magnitude of 700μg/m 3,500μg/m 3,and 300μg/m 3 treated by PEF for 8 min with a confined space.The results show that,after a relatively short period of PEF treatment,PM 2.5 concentration within the magnetic field range is significantly reduced,and the formation of macroscopic fluid behaviour is observed.A new method is expected to provide for the air quality local control temporarily.
