Schematic diagram of the working process of the sludge dryer
A complete sludge drying system includes screw conveyor, disc dryer, dust collector, steam condenser and deodorization tower. Wet sludge from a screw press sludge dewaterer typically contains 70-80% moisture. The sludge is continuously sent to the disc dryer by the screw conveyor, where it will be heated. The moisture material inside is gasified and sucked by the blower. The exhaust gas from the dryer enters the steam condenser after dust removal treatment. The condenser turns most of the vapor into condensed water. The exhausted gas will be deodorized by the biological deodorization tower, and then discharged from the chimney. Dried sludge also typically contains 20-30% moisture.  |
