DEVICE FOR RECOVERING NANOPOWDERS AND ULTRAFINE POWDERS CONTAINED IN A GAS

摘要

The invention relates to a device for recovering nanometer or sub-micron particles carried by a gas by means of generating a stabilized suspension, comprising a vessel (3) having a means (11) for injecting a liquid; gas discharge means (4) in the upper portion thereof, located near particle filtering means; and a particle suspension outlet means (9). Said invention also includes a liquid ring pump (2), for transferring and dispersing particles carried by a gas into a liquid, the pump including a means for introducing a gas laden with nanometer or sub-micron particles into the pump; a means (15) for injecting at least one liquid into the pump; a means for discharging the mixture obtained following the transfer. The vessel also includes a means for introducing said mixture into the vessel and at least one piezoelectric pellet (7), immersed in the vessel, designed to generate a fog of micron-sized droplets.
