Verfahren fuer die Rueckgewinnung von MGO und SO2 aus Rauchgasen

摘要

A method of recovering Mg0 and S02 from the flue gases of a combustion process and for producing a digestion liquor for use in a pulp plant wherein the gases containing Mg0 and S02 are passed upwardly through outwardly dispersed atomized sprays of liquid. The liquid droplets are collected outwardly of the atomizing disks and passed to successively lower atomizing units where the process is repeated. Water introduced above the lower (wet precipitator) set of atomizing disks strips the Mg0 fly ash from the gas to form a suspension which is used in the upper stages to react with S02 (absorption stage) and produce the digestion liquor.
