An air blower including a motor 2 having output shafts 21, 21 on both sides in the axial direction and two impellers 3, 3 mounted on the respective output shafts 21, 21, and two ducts 5, 5 that individually allow passage of the air blown out by rotation of each of the impellers 3, 3 in the same direction and discharge the air to the outside are included. At a part or the whole of each of the ducts 5, 5, a laminar flow section that makes the flowing air laminar flow. An ion generating section is arranged at each laminar flow section so that ions generated by the ion generating section can effectively be included in the air, increasing the ion concentration of ions discharged in a room together with the air.

The invention relates to a method and device for collecting nanoparticles which may be present in an aerosol. The invention consists of electrostatically collecting nanoparticles contained in an aerosol by a mechanism of particle charging by unipolar ion diffusion, followed by the application of a field without a corona effect, which makes it possible to deposit the particles in concentric rings on different parts of a single flat substrate oriented orthogonally to the aerosol circulation direction. The biggest particles are deposited towards the centre of the flat substrate and the finest particles towards the periphery of the flat substrate. The invention also relates to a method of operation and to the use of such a device for evaluating the exposure of workers or consumers to nanoparticles.

摘要:
There is provided an electric dust collection device which can effectively capture fine particles while avoiding a pressure loss. The electric dust collection device is provided with a charging electrode 73, a dust collection electrode 35, and a repulsive electrode 74. Along a flowing direction of an airflow, the dust collection electrode 35 is disposed downstream of the charging electrode 73, and the repulsive electrode 74 is disposed downstream of the dust collection electrode 35. The dust collection electrode 35 is formed of a conductive material which partitions a ventilation passage through the airflow pass in the flowing direction. The repulsive electrode 74 forms an electric barrier which has the same polarity as that of the charging electrode 73 with a posture that intersects the airflow in the flowing direction.
