Process and plant for mechanical and thermal dewatering of sludges |
摘要 |
A process and apparatus for mechanical and thermal dewatering of solid-liquid mixture, particularly industrial and sewage sludges, feeds the sludge to a dewatering device to produce a dewatered material which is then dried in a thermal drier. The dewatered sludge is reduced to a granulate-like structure without any intermediate stage and is then dried immediately afterwards. An apparatus for implementing the process includes a mechanical dewatering device being directly connected to a feed unit to produce a granulate-like structure and which is permanently connected to the thermal drier.
