Title
(EN) PLASMA DISCHARGE SELF-CLEANING FILTRATION SYSTEM
(FR) SYSTÈME DE FILTRAGE AUTONETTOYANT PAR DÉCHARGE DE PLASMA
Abstract
(EN)
The present invention is directed to a novel method for cleaning a filter surface using a plasma discharge self-cleaning filtration system. The method involves utilizing plasma discharges to induce short electric pulses of nanoseconds duration at high voltages. These electrical pulses generate strong Shockwaves that disintegrate and dislodge particulate matter located on the surface of the filter.
(FR)
L'invention concerne un nouveau procédé destiné à nettoyer une surface de filtre au moyen d'un système de filtrage autonettoyant par décharge de plasma. Ce procédé consiste à utiliser des décharges de plasma pour induire de brèves impulsions électriques d'une durée de l'ordre des nanosecondes à des tensions élevées. Ces impulsions électriques génèrent de fortes ondes de choc qui désintègrent et décollent les matières particulaires situées sur la surface du filtre.
