ETP Sludge Dryer 

Sludge Drying systems designed and manufactured by Kerone are suitable for small, medium, and large quantity sludge generators. The drying systems can be installed directly under the filter press for immediate loading or positioned at remote locations within the plant. During the thermal drying process, almost all water is evaporated, including surface water, capillary water, and cell water. Heat supply is required, preferably from combined heat and power generation systems. A significant portion of the drying heat is recovered from the exhaust gases and recirculated to improve overall efficiency.

Characteristics of Technical Structure:

• The full-strength KERONE sludge drying machine has strong resistance to overloading, the ability to handle large processing capacities, low fuel consumption, and reduced drying costs.
• By using the co-current drying method, the flue gas and wet materials enter the dryer from the same side. High-temperature flue gas ensures high evaporation intensity, while the low outlet temperature results in high thermal efficiency.
• The operating parameters can be adjusted according to the nature of different materials, allowing the formation of a stable and uniform material curtain inside the dryer cylinder for more complete heat exchange.
• The new feeding and discharging device eliminates blockage, discontinuity, non-uniformity, and material return in the tumble dryer, thereby reducing the load on the dust removal system.
• The new internal structure enhances cleaning and heat conduction of dispersed materials, eliminates sticking on the inner wall of the cylinder, and improves adaptability to materials with high moisture and viscosity.
• The new sludge drying equipment achieves “zero horizontal thrust,” significantly reducing wear on the retaining wheel and ensuring smooth and reliable cylinder operation.
• The dryer adopts an aligning roller device that maintains linear contact between rollers, greatly reducing wear and power loss.
• By using unique bulk sludge delay drying technology, uniform drying of sludge is ensured.
