Abstract

L'invention concerne le dépoussiérage électrostatique. Un ionisateur destiné à un précipitateur électrostatique comporte un venturi 27 dans lequel un disque de cathode 50 établit un champ électrique qui charge électriquement les particules contenues dans le gaz qui traverse le venturi. Des électrodes de focalisation 53, 54 sont associées à la cathode pour réduire au minimum le dépôt de particules à l'intérieur du venturi. Application au dépoussiérage des gaz de combustion des centrales thermiques.The invention relates to electrostatic dust removal. An ionizer for an electrostatic precipitator has a venturi 27 in which a cathode disc 50 establishes an electric field which electrically charges the particles contained in the gas passing through the venturi. Focusing electrodes 53, 54 are associated with the cathode to minimize the deposition of particles within the venturi. Application to the dedusting of combustion gases from thermal power stations.
