ACOUSTIC SYSTEM OF GAS AND DUST CLEANING OF AERIAL EFFLUENTS OF IMPULSE 2 TYPE Russian patent published in 2008 - IPC B01D47/06 B05B17/06 

FIELD: technological processes.

SUBSTANCE: invention is related to the method of wet dust collection and may be used in chemical, textile, food, light and other industries for purification of dusted gases. Acoustic system of gas and dust cleaning of aerial effluents contains casing, which is installed horizontally and which has cylindrical form with the contact zone in the central part, on the left of which, serially along the casing axis, at least two sprayers are installed, and in the right part of casing, after the contact zone there is drop catcher installed with the drain in the bottom part of casing. Nozzles are connected to every sprayer for compressed air and nozzles for water with stop and control valves that connect nozzles with headers that are accordingly installed in pipelines that supply water and compressed air, at that every of headers is equipped with manometers for control of water and compressed air pressure. Sprayers represent acoustic sprayers that contain casing with installed inside generator of sound oscillations of ultrasonic frequency range in the form of nozzle and annular volumetrical resonator. Casing of sprayers is made in the form of vertically installed cylindrical bushing, in the top part of which tube is installed for air supply, and tube for liquid supply is installed perpendicularly to its axis. Inside casing, coaxially to it, bushing is rigidly fixed with top and bottom flanges, at that the bottom flange is rigidly fixed in the bore made in casing. Inside bushing, coaxially to it, there is rod installed with diameter d, at the end of which annular volumetrical resonator is pressed, made in the form of cup with conical surface, and in tail part of rod fixing discs are installed that interact with internal surface of bushing. In the bottom flange there is at least one nozzle at the angle to the axis of resonator, the value of which lies in the following interval of values: 20°-40°, at that continuation of nozzle axis lies on circumference located in the middle part of resonator conical surface.

EFFECT: increase of efficiency and reliability of dust collection.
