DUST ARRESTER AND OUTPUT DEVICE OF DUST ARRESTER Russian patent published in 2015 - IPC B04C5/12 

FIELD: machine building.

SUBSTANCE: dust arrester contains casing, in its top cylindrical part a inlet device is made, it contains slotted nozzle for contaminated gas inlet, installed tangentially to the casing internal surface. The casing bottom part is made as truncated cone with top downwards; under the input device, inside the casing, coaxially with its vertical axis the output device for cleaned gas is located. The output device casing is made cone, with top downward, and contains a gathering chamber for cleaned gas, and outputs of cleaned gas to the specified chamber, made in form of multiple ring channels located in series along the generatrix of the cone casing. In top part of the output device the device for cleaned gas removal is located, it contains gate made with possibility to adjust the passage of the cleaned gas between the gathering chamber of the cleaned gas and device for cleaned gas removal. The gate disk contains passage hole connecting the volume of the gathering chamber of cleaned gas with device for the cleaned gas removal. Between the casing of the cleaned gas output device and dust arrester casing a cone shell is installed. To the bottom part of the dust arrester casing the dust hopper is connected.

EFFECT: invention increases efficiency of catching of the fraction of light, easy gliding dust particle, with simultaneous catching of coarse and fine particles.
