ACOUSTIC DUST-ARRESTER INSTALLATION OF AKF-2 TYPE Russian patent published in 2008 - IPC B04C9/00 

FIELD: different branches of industry and agriculture; production of the acoustic dust-arrester installations.

SUBSTANCE: the invention is pertaining to the equipment used for the dust collection. The dust-arrester installation includes the cyclone, the speaker with the generator of the sound vibrations disposed in its upper part. The lower part of the speaker is connected to the peripheral inlet of the gas stream from the cyclone. The installation is supplied with the fine filter containing the cyclone component, the peripheral inlet of the gas stream made in the form of the inlet fitting pipe, connected by the air duct with the axial outlet fitting pipe of the cyclone and connected at the right angle with the body of the cyclone component having two coaxial fitting pipes, on one of which the filtering component is fixed, and on the other - the storage bin used for the dust collection, which is made in the form of the dust-collecting bag. The filter contains the mechanism of the recuperation made in the form of the rigidly fixed on the coaxial with the filter shaft of at least two plates. The shaft is actuated in rotation by the drive gear fixed in the upper part of the wire framework of the filter. The cyclone component is supplied with the fixed on it fan; the inlet fitting pipe is fixed coaxially to the axis of the fan; and the fitting pipe to which the storage bin the dust collection is connected, has the length, which is at least, twice exceeding the length of the fitting pipe, on which the filtering component is fixed. The axes of these fitting pipes coincide with axes of the filtering component and the dust-collection bag. The technical result of the invention is the increased efficiency of the dust arresting.

EFFECT: the invention ensures the increased efficiency of the dust arresting.
