Abstract: front page image
(EN)The present invention relates to a multichannel-type diffusion charger for the real-time measurement of the size distribution of submicron particles, and to a method for the real-time measurement of the size distribution of submicron particles using same. The multichannel-type diffusion charger for the real-time measurement of the size distribution of submicron particles according to the present invention includes: a particle charger (10) for charging particles contained in aerosol air; a plurality of channels (20) for providing a passage for the air in the particle charger (10) such that the air is divided and flows through the passage; and a current measuring device electrically connected to outlet ends of each of the channels to detect a plurality of current values corresponding to the amount of discharge of particles passed through each of the channels. The multichannel-type diffusion charger of the present invention can be manufactured into a small size with a low cost while minimizing the loss or stagnancy of the amount of charged particles. The multichannel-type diffusion charger for the real-time measurement of the size distribution of submicron particles, and the method for the real-time measurement of the size distribution of submicron particles using same, according to the present invention, establish a plurality of simultaneous equations corresponding to the number of variables, and thus calculate and derive variable values in an accurate manner without the need for setting arbitrary values to a portion of the variables, in deriving a plurality of variable values by applying current value data to the algorithm consisting of variables for providing information on the particle size distribution, such as the total particle number concentration, the geometric mean diameter, and the geometric standard deviation.
(FR)L'invention concerne un chargeur par diffusion multicanaux utilisé pour mesurer en temps réel la granulométrie de particules submicroniques, et un procédé pour mesurer en temps réel la granulométrie de particules submicroniques au moyen du chargeur. Le chargeur par diffusion multicanaux selon l'invention utilisé pour mesurer en temps réel la granulométrie de particules submicroniques comprend : un chargeur de particules (10) pour charger des particules contenues dans un aérosol d'air; plusieurs canaux (20) permettant le passage de l'air dans le chargeur de particules (10) de manière que l'air soit divisé et s'écoule dans le passage; et un dispositif de mesure du courant qui est relié électriquement aux extrémités de sortie de chacun des canaux pour détecter plusieurs valeurs de courant correspondant à la quantité de décharge des particules circulant dans chaque canal. Le chargeur par diffusion multicanaux peut être produit à de petites dimensions de manière peu onéreuse, de façon à réduire au maximum les pertes ou la stagnation de particules chargées. Selon l'invention, le chargeur par diffusion multicanaux utilisé pour mesurer en temps réel la granulométrie de particules submicroniques et le procédé pour mesurer en temps réel la granulométrie de particules submicroniques au moyen du chargeur permettent d'établir plusieurs équations simultanées correspondant au nombre de variables, et ainsi de calculer et dériver des valeurs de variables de manière correcte sans qu'il soit nécessaire de fixer des valeurs arbitraires pour une partie des variables, plusieurs valeurs de variables étant dérivées en appliquant à l'algorithme des données de valeur de courant constituées de variables pour fournir des informations sur la granulométrie, telles que la concentration de particules totale, le diamètre géométrique moyen et les écarts-types géométriques.
