ACOUSTIC SYSTEM OF GAS-DUST CLEANING OF AIR-BORNE EMISSIONS Russian patent published in 2008 - IPC B01D47/06 B05B17/06 

FIELD: ventilation, wet dust collection.

SUBSTANCE: invention relates to gas-dust cleaning of air-borne emissions. The system consists of case, placed horizontally and with a cylindrical shape with a contact zone, length of one contact zone, on the left of the central part of which, in series along the axis of the case, there are at least two atomisers, while on the right part of the case, after the contact zone, with length of one contact zone, there is drip pan with a sink in the lower part of the case. In each atomiser there are connection pipes for compressed air and connection pipes for water with sealing and regulating valves, joining the connection pipes to collectors, respectively located in the pipelines carrying water and compressed air. Each of the collectors is equipped with manometers for monitoring pressure of the water and compressed air. The atomisers are in the form of acoustic atomisers for atomising liquids, and consist of case. Inside the case there is generator of acoustic oscillations in the form of a nozzle and a resonator, made in the form of concentric ring-shaped apertures, located on a plane perpendicular to the axis of the case. A ring with a conical surface is joined to the case, and serves as the nozzle for atomised liquid. The atomiser serves to form a film of liquid, covering the output of the generator, and is mounted in the case using a hollow bar with a screwed swirler at the end and a pad for mounting a ring-shaped platform, on which liquid flows out from the atomiser. The resonator has at least one extra spherical cavity, located in the wall of the ring. The spherical cavity is linked with a calibrated aperture with a ring-shaped aperture, formed by the butt end surfaces of the case and ring from the side of the conical surface. The ring is put with provision for fixed displacement along the axis of the case through a threaded connection.

EFFECT: increased effectiveness and reliability of the process of dust collection through increasing the degree of dispersion of the liquid using the atomisers.
