DEVICE FOR AIR CLEANING OF DUST AND AEROSOLS Russian patent published in 2000 - IPC

FIELD: separation of disperse particles from gas with the use of the electrostatic effect, applicable in all fields of industry and in domestic rooms. SUBSTANCE: the device is based on the use of the electrostatic effect and operates as an electrostatic precipitator. The device has a body accommodating corona-forming and precipitation electrodes of opposite polarities. Installed near the electrodes are two additional electrodes, one of which is passive, and the other electrode is electrically coupled to the precipitation electrodes and serves as a generator of negatively charged aerons. The device has a vessel with aromatic or medicinal substances. The given device provides for generation of flow of negatively charged aerons in air already cleaned of dust and aerosols, in which the concentration of positively charged aerons is reduced to their background value, as well as for saturation of cleaned air with molecules of aromatic substances without any use of solvents, atomizers, inhalators, fans and other known means. EFFECT: enhanced efficiency. 1 dwg
