Shenyang Yitong produces a new high-viscosity sludge dryer
Sludge drying is a process that uses heat to further remove capillary water from dewatered sludge, increasing the solid content to between 70% and 90%. This method is widely applied, particularly in thermal drying systems, which all require an external heat source. In addition to the dryer itself, the system typically includes components such as sludge feeders, auxiliary heating units, air supply mechanisms, heat recovery systems, dust control measures, ash discharge units, and automated control systems. These elements work together to ensure efficient and safe operation.
Northeastern University Shenyang Yitong Science and Technology Co., Ltd. has developed advanced sludge dryers capable of handling high-viscosity and high-moisture materials. The equipment can effectively dry materials with up to 80% moisture content, making it suitable for a wide range of applications. The drying system operates under full negative pressure, ensuring a safer and more controlled environment. It features direct heat transfer devices, allowing precise control over the final moisture level of the dried material. The system also incorporates low-temperature mechanical components, which contribute to its reliability, simplicity, and low failure rate.
This sludge drying equipment offers numerous advantages, including broad adaptability, cost-effective operation, no clogging issues at the sludge nozzle, flexible and adjustable system performance, ease of operation, and fully automated functionality. It is ideal for various applications such as sludge incineration, agricultural reuse, production of construction materials, non-agricultural use of sludge, landfilling, and mixed treatment with other waste materials. The technology is widely used for drying activated sludge, sewage sludge, petrochemical sludge, paper sludge, printing and dyeing sludge, tannery sludge, electroplating sludge, municipal wastewater treatment plant sludge, bio-fermentation residues, and other high-moisture by-products. Its versatility makes it a valuable solution across multiple industries.
