(FR) ELIMINATION DE SOLVANTS
Abstract
(EN)
A solvent cleaning apparatus is provided comprising a container (10) for holding a liquid solvent; a heater for heating the solvent in the container, a vapour space (14) arranged to receive vapour from the solvent chamber through which articles can be passed to clean them, a vent for venting gas containing solvent vapour from the solvent container, the vent comprising a condenser (20) for condensing the solvent vapour and an electrostatic electrode (24) arranged in the vicinity of the condenser which is electrostatically charged to attract or repel the solvent vapour onto the cooled surface of the condenser, thereby increasing the efficiency of removal of the vapour from the vented gas and greatly reduces the level of emission of the vapour to the atmosphere.
(FR)
L'invention concerne un appareil de nettoyage de solvants comprenant un récipient (10) destiné à contenir un solvant liquide; un dispositif de chauffage destiné à chauffer le solvant à l'intérieur du récipient; un espace vapeur (14) conçu pour recevoir les vapeurs de la chambre de solvant dans laquelle on peut faire passer les articles pour les nettoyer; un évent destiné à évacuer les gaz renfermant des vapeurs de solvant du récipient de solvant, ledit évent comprenant un condenseur (20) destiné à condenser les vapeurs de solvant et une électrode (24) électrostatique, disposée à proximité du condenseur, et qui est chargée électrostatiquement pour attirer ou repousser les vapeurs de solvant sur la surface refroidie du condenseur, ce qui permet de rendre l'élimination des vapeurs provenant des gaz évacués plus efficace et de réduire considérablement le niveau d'émission de ces vapeurs dans l'atmosphère.
