中国专利申请号201410549444.5，发明名称为“旋风式荷电水雾空气净化除尘方法及其系统”，通过水雾与含尘气流混合后再经过高压电场荷电以获得含尘荷电气雾，然后含尘荷电气雾在一个混合反应室充分混合后，再进入反转式旋风除尘器进行分离除尘。由于该方法水雾与含尘气流先混合后再统一在电场中荷电，气流中的颗粒物和水滴被荷上了同极性的电荷，相互之间存在相互排斥的静电力，不利于水滴与颗粒物之间的吸附和凝并。由于不是水雾在喷嘴处直接荷电，因此雾滴所获得的荷质比较小，荷电水雾对除尘效率的贡献不会太大。

本专利申请的工作原理为：
含尘气流首先经过由静电雾化喷嘴喷出的水雾区，二者混合后进入到轴流旋风过滤筒10的导流叶片105处，并在导流体106与外筒104之间的通道内近距离接触、碰撞和吸附，最终凝并在一起形成大粒径的液固两相颗粒物。在此过程中悬浮物的平均粒径及平均质量大大增加，使其在下游所受离心力也大大增加，在导流叶片105的作用下，液固两相颗粒物在受离心力作用被甩向轴流旋风过滤筒10的内壁，形成含尘液膜层，并在惯性力的作用下沿着外筒104内壁螺旋向前移动，最终被截留掉入排尘槽103中，在重力和负压吸尘风机的动力作用下被收集到液固两相收集箱14之中，而洁净气流则从出风口102排出。通过本发明所述装置可有效将空气中微小粒径固体颗粒物凝并为大粒径的液固两相颗粒物，从而增加颗粒物被捕集的效率。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
