METHOD AND DEVICE FOR COARSE SEPARATION OF SOLID PARTICLES FROM GASES CONTAMINATED WITH SOLID SUBSTANCES Russian patent published in 2013 - IPC F27B15/12 B01D50/00 

FIELD: machine building.

SUBSTANCE: device includes supply pipeline (1) located vertically or slantwise and discharge pipeline (2) that is arc-shaped at least in some sections and has the possibility of its being connected, when required, to the separation device for separation of remained solid substances from pre-cleaned gas. The device has the possibility of supplying through the supply pipeline to its lower end side (3) of gases (G) contaminated with solid substances, and upper end side of supply pipeline is closed with cover plate (4). Arc-shaped discharge pipeline (2) is located on supply pipeline (1) so that a continued part of pipeline (5), which has the shape of a blind hole, for separation of solid particles is formed. Besides, arc-shaped discharge pipeline (2) is made with a curvature in the form of an arc of circle or an arc formed of straight segments, with the radius that is by 3-5 times more than width for clear opening of the arc-shaped discharge pipeline (2).

EFFECT: reliable separation of solid substances from gas contaminated with them.
