  • Description: 24,125. Sandberg, E. S., and Sundblad, G. K. Oct. 30, 1911, [Convention date]. Carbonizing processes and apparatus; retorts. -The destructive distillation of organic matters suspended or dissolved in liquids such as waste lye from the manufacture of wood pulp is effected by evaporating the liquid in a thin layer and partly carbonizing the residue on an externally heated surface, and then completing the carbonization in an externally heated screw-feeder, an ordinary retort, or the like. In the apparatus shown, the liquid is supplied by a rotating pipe 4 to a conical surface 6, which is heated externally to 400-500‹ C. by the gases from the furnace 16, and the residue is removed by means of rotating scrapers and passed through externally heated screw-feeders 8, 11. The products of evaporation and distillation from the surface 6 and the screw-feeders escape together through a pipe 15 leading from the upper screw-feeder. Reference is made to a known process in which the waste lye alone is completely carbonized in a thin .layer on an externally heated surface.
