VENTURI-PIPE -TYPE GAS PURIFICATION DEVICE Russian patent published in 2009 - IPC B01D47/10 B05B17/06 

FIELD: mechanics.

SUBSTANCE: venturi-pipe-type gas purification device includes a confuser, neck, diffuser, regulating insert coupled by a rod with the drive, system of irrigation and clamp arranged in diffuser. The said regulating insert represents several coaxially spaced elements. Note that the external element is rigidly fixed on the said rod by means of spokes, while the internal element is arranged on the rod to move lengthwise thereon and features a bulge located between the spokes of the external element. The irrigating device represents an acoustic atomiser for spraying liquids, and comprising the case with the generator of acoustic vibrations fitted therein and representing a combination of a nozzle and a resonator and a pipe for supply of the sawing agent and liquid. The case represents a glass with the bottom. The generator of acoustic vibrations is arranged inside the case and represents a hollow core with a wedge slot and a nozzle. The liquid is supplied to the circular gap formed between the resonator external surface and the nozzle internal surface, while the liquid supply channel is located tangentially to the glass internal surface and represents a rectangular slot. Air is forced through the union fitted in the case and the resonator orifice to get at least in one wedge slot arranged at the angle to the resonator axis. Note here that angle varies from 30° to 60°. A helical guide device is arranged in the circular gap between the glass internal surface and the resonator external surface to facilitate swirling the liquid fed via the channel.

EFFECT: decreased power consumption.
