DUSTED GAS PURIFICATION SYSTEM Russian patent published in 2008 - IPC B01D47/00 F23D11/34 

FIELD: mechanics.

SUBSTANCE: invention relates to wet-type dust collection techniques and can be used in chemical, textile, food, light and other industries to purify gases. The dusted gas purification system contains a cylindrical case arranged with a contact area in its central part, at least, two nozzles located consecutively along a gas flow, and a drop trap fitted beside the contact area with the drain in the case bottom. Nozzles are arranged on the case axis and are acoustic atomisers. Compressed air and water branch pipes are fed to each nozzle, the said branch pipes being furnished with stuff-off and adjusting valves communicating them with manifolds arranged in the pipes feeding compressed air and water. Every collector is furnished with a compressed air and water pressure gauges. Every atomizer includes the case with a barrel and a central core with the tapered collar forming the generator of acoustic oscillations in the form of a nozzle and a resonator, a ring with a tapered surface connected with the case and a sprayer made in the form of an annular space limited by a cylindrical sleeve with regularly spaced holes to feed liquid. The resonator is made in the form of, at least, one spherical cavity arranged in the central core body communicating with the calibrated orifice with an annular slot formed by the barrel and central core end faces' surfaces on the tapered collar side. The central core is arranged to regularly move along the case axis by means of a threaded joint fixed by locknuts. In a preferable version of the system, the nozzle resonator is designed to adjust controlled acoustic oscillations frequency by varying the width of annular slot formed by the barrel and central core end faces' surfaces on the tapered collar side. Here, between the barrel bottom and the end face plane, the central core is arranged on the side opposite to the collar tapered surface along with calibrated gaskets with a thickness corresponding to preset frequency of acoustic oscillations.

EFFECT: higher efficiency and reliability of dust separation.
