Title:
SYSTEM AND PROGRESS FOR TREATING WET SLUDGE BY DRYING AND INCINERATING
Document Type and Number:
WIPO Patent Application WO/2008/128465
Kind Code:
A1
Abstract:
A system for treating wet sludge by drying and incinerating, includes low temperature
pyrolysis apparatus, centrifugal apparatus, steam condenser, filtrate recovery
apparatus and sludge incinerating apparatus. The corresponding treading process
comprises reacting wet sludge with saturated steam at low temperature condition
to carry out thermal decomposition, centrifuging the wet decomposed sludge,
condensing the unsaturated steam produced by pyrolysis through condenser,
collecting condensate and filtrate from centrifugal apparatus by using filtrate
recovery apparatus, using the centrifugated sludge and remaining gas from steam
condenser as fuel to incinerate.
