Process and apparatus for continuous work-up of phosphorus-containing residues

摘要: Continuous work-up of moist, phosphorus-containing residues, particularly residues which originate from the filtration yellow phosphorus or effluent water. To this end, intimate contact is produced, in an electrical precipitation zone adapted to free furnace gas dust, between moist residue and hot dust originating covering bottom portion said zone. Residue are contacted a quantitative ratio 1 2. Resulting, substantially phosphorus-free mechanically removed together with precipitated gas, A phosphorus/water-mixture produced by vaporization passed through mixture introduced jointly dust-free coming into condensation placed downstream zone, wherein precipitated.
