Patent ID: 8182567

Claim:
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.
