    • The present invention is directed to a method of removing aerosols using a radiation effect. Specifically, the method applies a dc current in a cell between a porous electrode exposed to radiation and a porous electrode shielded from radiation; allows the aerosol-containing gas to flow in the cell from the exposed electrode to the shielded electrode and exposing the gas to radiation so that streams of positive and negative ions are formed by radiation-induced ionization; causes the positive and negative ions to collide with the aerosol particles in the cell to form charged aerosol particles; subsequently passes the charged aerosol particles through the shielded electrode so that the aerosol particles electrified with positive ions are deposited or trapped on the shielded electrode if the latter has a negative polarity or that the aerosol particles electrified with negative ions are deposited or trapped on the shielded electrode if the latter has a positive polarity; thereby generates charged aerosol particles of a single polarity in the area just downstream of the shielded electrode as a result of collisions with large quantities of ions that have been electrified to the same single polarity as that of the shielded electrode; and then either deposits the charged aerosol particles of a single polarity on the surface of a substance by an electrostatic force or traps the charged aerosol particles of a single polarity on an electrode or a filter. The method is capable of removing the aerosol particles with an extremely high efficiency.
    • 本发明涉及使用辐射效应去除气溶胶的方法。 具体地,该方法在暴露于辐射的多孔电极和屏蔽辐射的多孔电极之间的电池中施加直流电流; 允许含气雾剂的气体在电池中从暴露的电极流到屏蔽电极,并将气体暴露于辐射,从而通过辐射诱导的电离形成正离子和负离子流; 导致正离子和负离子与细胞中的气溶胶颗粒碰撞以形成带电的气溶胶颗粒; 随后将带电气溶胶颗粒通过屏蔽电极,使得带正电离子的气溶胶颗粒沉积或捕获在屏蔽电极上,如果后者具有负极性,或者带负电离电荷的气溶胶颗粒沉积或被捕获在屏蔽电极上 电极,如果后者具有正极性; 从而与已经通电到与屏蔽电极相同的单极性的大量离子碰撞的结果,在屏蔽电极正下游的区域产生单极性的带电气溶胶颗粒; 然后通过静电力将单一极性的带电气溶胶颗粒沉积在物质的表面上,或者将电极或过滤器上的单极性的带电气溶胶颗粒捕获。 该方法能够以极高的效率去除气溶胶颗粒。
