摘要： An air purification system (10) for use with rail car HVAC system to remove or destroy harmful pathogens in the air. The air purification system (10) has a housing (12) with an inlet (14), an outlet (18), and a passageway (16) extending between the inlet (14) and the outlet (18). An intense field generator and filter (32) is used to charge any particles in the air and remove them from the air flow. An ultraviolet radiation source (30) is positioned to direct ultraviolet illumination into the passageway. Finally, a dielectric barrier discharge unit (34) having a high voltage electrode coupled to a dielectric barrier and a ground electrode spaced apart from the high voltage electrode is used to form a low temperature plasma chamber is in communication with the passageway (16) so that the ions created in the plasma chamber will attach to and destroy any remaining particles in the air flow.

摘要： 一种集尘机构、车载空气净化器和风扇，集尘机构包括发生极组件（100），发生极组件（100）包括发生极支架（101）、发生极板（102）和发生极丝，发生极板（102）和发生极丝间隔交错设置于发生极支架（101）内；收集极组件（200）包括收集极支架（201）、排斥极板（203）和收集极板（202），排斥极板（203）和收集极板（202）间隔交错设置于收集极支架（201）内；发生极支架（101）和收集极支架（201）可拆卸连接，且收集极板（202）和发生极丝通过磁吸方式连接并导通。该结构便于收集极板和发生极丝一同接入电源，实现收集极组件和发生极组件之间的无导线方式导通，简化了线路结构，避免了导线连接导致的拆卸困难，进而使得收集极组件和发生极组件便于拆装，拆卸后发生极组件不会对清洗收集极板造成干扰，降低清洗难度。

An intense field generator (52) and filter (54) is used to charge any particles in the air and remove them from the air flow.
