Abstract

Fremgangsmåte til separering av smelte- og fortrinns- vis også faststoff-partikler fra en gasstrøm hvor den nevnte strøm stammer fra forgassingen av avlut, fortrinnsvis svartlut, fra produksjonen av masse (pulp) og omfatter både gassformede stoffer (4) og smelte- og eventuelt også faststoff-partikler (5), hvil- ken gasstrøm ledes til en separasjonsnordning (2) hvor i det minste en viss del, fortrinnsvis hoveddelen av de nevnte partikler (5) separeres fra gasstrømmen (4), idet den nevnte strøm av gassformede stoffer (4) inneholdende smelte- og/eller faststoff-partikler (5) tvinges til å bevege seg i en krum bane og at i det minste den ytre omkrets av den krumme bane er avgrenset av et bevegelig væskelag (12), idet de nevnte partikler (5) separeres fra gasstrømmen (4) ved at de blandes sammen med og fortrinnsvis også oppløses og avkjøles i, væskelaget (12).A process for separating melting and preferably also solid particles from a gas stream wherein said stream originates from the gasification of liquor, preferably black liquor, from the production of pulp (pulp) and comprises both gaseous substances (4) and melting and possibly also solid particles (5), the gas stream being conducted to a separation device (2) where at least a certain part, preferably the main part of said particles (5), is separated from the gas stream (4), said stream of gaseous substances (4) containing melting and / or solid particles (5) being forced to move in a curved web and at least the outer periphery of the curved web being bounded by a moving liquid layer (12), said particles (5) is separated from the gas stream (4) by mixing with and preferably also dissolving and cooling in the liquid layer (12).
