Method and device for coarse separation of solid particles from solid-laden gases

A device for coarse separation of solid particles from solids-laden gases from a reactor for treatment of particulate feed materials by means of treatment gases, the device comprising:

• a vertically upwardly extending or obliquely upwardly extending feed line receiving treatment gases and solid particles from the reactor;
• and a drain line which is arcuate at least along certain portions thereof;
• the feed line having a lower end which receives the solids-laden gases, the feed line has a closed upper end,
• the arcuate drain line being arranged on and arcuately curving off the feed line at a position along the feed line below the closed upper end forming a blind hole-type line projection in the feed line above the position along the feed line and the arcuate connection being shaped for separating solid particles from the treatment gases, and
• the arcuate drain line being curved in the form of an arc of a circle or an arc constructed from straight segments, having a radius of 3-5 times a clear width of the arcuate drain line.
