Abstract

Les poussières fines et aérosols de flux gazeux sont déposés dans un électrofiltre, sous l'action du champ électrique, sur un film liquide relié à la terre et recouvrant la surface de précipitation. Le film liquide est produit en mélangeant le flux gazeux, avant son entrée dans l'électrofiltre, avec une vapeur qui se condense sur la surface de précipitation de l'électrode. Dans le cas le plus simple, le flux gazeux est saturé de vapeur d'eau avant son entrée dans l'électrofiltre. Le film liquide s'écoule vers le bas et se renouvelle ainsi continûment. Les poussières ou aérosols déposés sur l'électrode de précipitation sont ainsi également évalués par le film liquide.The fine dust and gas stream aerosols are deposited in an electrostatic precipitator, under the action of the electric field, on a liquid film connected to the earth and covering the precipitation surface. The liquid film is produced by mixing the gas flow, before entering the electrostatic precipitator, with a vapor which condenses on the precipitation surface of the electrode. In the simplest case, the gas flow is saturated with water vapor before it enters the electrostatic precipitator. The liquid film flows downwards and thus renews itself continuously. The dust or aerosols deposited on the precipitation electrode are thus also evaluated by the liquid film.
