Patent ID: 8690995

Claim:
A device for recovering nanometer or sub-micron particles carried by a gas by generating stabilized suspensions of nanometer or sub-micron particles, the device comprising a vessel which comprises: means for injecting at least one liquid into the vessel; gas discharge means located in an upper portion of the vessel after particle filtering means; particle suspension outlet means; a liquid ring pump, configured to transfer and disperse all or part of the nanometer or sub-micron particles carried by a gas in a liquid, the pump including: means for introducing a gas laden with nanometer or sub-micron particles into the pump; means for injecting at least one liquid into the pump; and means for discharging a mixture comprising the liquid laden with particles and the gas obtained at the end of the transfer of particles; and wherein the vessel further comprises: means for introducing the mixture into the vessel; and at least one electro-acoustic transducer having piezoelectric pellets, configured to be immersed within the vessel in a liquid, the transducer configured such that acoustic waves created at a level of the transducer propagate up to the surface of the liquid in which it is immersed and generate a fog of micron-sized droplets above the surface of the liquid.
