Title
(EN) ELECTROSTATIC PRECIPITADOR WITH KEYING TO SELECTIVE ACTION ON EACH INDIVIDUAL EMITTING ELECTRODE
(FR) PRÉCIPITATEUR ÉLECTROSTATIQUE AVEC CLAVIER POUR ACTION SÉLECTIVE SUR CHAQUE ÉLECTRODE INDIVIDUELLE D’ÉMISSION
Abstract
(EN)
Precipitador characterized by the fact that it has individual keys [figure 2, (6)] for each or selected emission electrodes [figure 2, (4) and (5)], what provides the E.P. with the capacity of selective and individual connection/disconnection of the electric feeding of the emission electrodes by action of the Automatic Control System. With this innovation, a redistribution of the collected mass can be achieved, through a direct action on the emission electrodes where the located sparking occur, meaning that a more efficient performance of the Automatic Controlling System, allowing bigger intervals of time for activation of the System of Mechanical Beating (that is, allowing a decrease in the Rapping Frequency), resulting in increase of the Collection Efficiency and of the Useful Life of the Electrostatic Precipitador.
(FR)
L’invention concerne un précipitateur électrostatique caractérisé en ce qu’il possède des touches individuelles [Figure 2, (6)] pour chacune des électrodes d’émission ou pour celles sélectionnées [Figure 2, (4) et (5)], ce qui procure à l’ESP la capacité d’une connexion/déconnexion sélective et individuelle de l’alimentation électrique des électrodes d’émission par l’action du système automatique de contrôle. Grâce à cette innovation, il est possible d’obtenir une redistribution de la masse collectée, par action directe sur les électrodes d’émission où l’étincelle localisée se produit, ce qui se traduit par une meilleure efficacité du système automatique de contrôle, autorisant de plus grands intervalles de temps entre les activations du système de battage mécanique (autrement dit, autorisant une diminution de la fréquence d’ébranlage), résultant en une augmentation de l’efficacité de la collecte et de la durée de vie du précipitateur électrostatique.
