DUST SEPARATION SYSTEM Russian patent published in 2008 - IPC B04C9/00 B01D50/00 

FIELD: mechanics.

SUBSTANCE: proposed system incorporates pipelines, first and second vortex dust separators, each incorporating a cylindrical casing with an upper tangential inlet branch pipe, a swirler communicating with the lower inlet branch pipe furnished with a tapered dust baffle washer arranged along the casing axis, an axial outlet branch pipe and a taper dust collector bin with a dust release branch pipe furnished with a rotary lock and a fan with its intake branch pipe communicating with the first dust separator axial outlet branch pipe and its pressure branch pipe communicating with the second dust separator inlet branch pipes. The proposed system is additionally furnished with the third vortex dust separator that features a similar design but smaller overall sizes and lower efficiency compared to the aforesaid first and second dust separators. Note that the aforesaid third dust separator inlet branch pipes communicate with the second separator bin and its axial outlet branch pipe is connected to the sleeve filter, its outlet being connected to the first dust separator lower inlet branch pipe. Note here that the starting gas feed pipeline communicates with the first dust separator upper and lower inlet branch pipes.

EFFECT: higher efficiency of purifying gas with finely-dispersed particles.
