Abstract:
PCT No. PCT/EP92/01426 Sec. 371 Date Dec. 27, 1993 Sec. 102(e) Date Dec. 27, 1993 PCT Filed Jun. 24, 1992 PCT Pub. No. WO93/00562 PCT Pub. Date Jan. 7, 1993.In order to considerably reduce expenditures for the dewatering of sludges, particularly from sewage treatment facilities, and thereby perform the step from a sticky, wet solid to a flowable solid granulate practically without the re-admixture of material, it is proposed to employ a solid bowl sludge centrifuge as the dispersing member in a subsequently connected convection dryer for further dewatering of the wet solids particles that are ejected with a dry substance content of approximately 25-35 weight percent. The wet solids particles that are ejected at high speed in the form of a film of particles from the outlet of the solid bowl sludge centrifuge are surrounded by the hot drying gas while still on their trajectory and are pre-dried to a dry substance content of approximately 65 weight percent (FIG. 5).
