SDL&SDP Sludge Drying System

SDL&SDP Sludge Drying System

Conventional sludge drying system typically reduces sludge moisture content to 60%-85%.

SHANGCHEN sludge drying systems can reduce moisture content to 10%-40%, achieving substantial sludge volume reduction and reduced disposal costs.

The dried sludge can be transformed into valuable resources for applications such as fertilizer production, soil amendment, alternative fuel, and construction                materials.

Applications

The system is widely applicable to municipal and industrial sludge volume reduction, serving industries such as chemical processing, electroplating, printing and         dyeing, leather, papermaking, pharmaceuticals.

Product Categories

Based on different application requirements, SHANGCHEN provides two sludge drying solutions: the SDL Mild-Heat Sludge Drying System and the SDP Reduction          Sludge Drying System.

SDL Mild-Heat Sludge Drying System

The SDL System is based on a mild-heat dehumidifying pump and adopts a convective heated air circulation drying method to remove moisture from the sludge. The system reclaims both latent heat of the moisture vapor and sensible heat from the circulating airflow during the process, achieving efficient heat utilization.

Product Features

Efficient Reduction

By reducing sludge moisture content to 10%-40%, the system achieves over 80% sludge volume reduction, significantly reducing transportation and disposal costs.

Energy-Efficient

Featuring a closed-loop design and advanced dehumidifying heat pump technology, the system achieves energy-efficient operation with a SMER of over 4.2 kg H₂O/kWh. The system can reduce sludge moisture content from 80% to 30% with an energy consumption of 170 kWh/t.

Intelligent Operation

Integrated design for simplified installation; fully automated operation with PLC-based intelligent control; enabling remote unattended operation.

Zero Emission

Enclosed design prevents odor leakage, eliminating the need for additional deodorization equipment.

Safer Operation

The system minimizes dust and explosion hazards by operating at a temperature range of 40-75°C. The dried sludge temperature remains below 50°C, enabling direct disposal without additional cooling.

SDP Sludge Reduction Drying System

The System features hollow blades and a hollow sandwich structure for indirect heating, delivering a high ratio of heat transfer area to material volume. Furthermore,  the blades are engineered to prevent sludge adhesion, delivering consistently superior and stable thermal efficiency.

The SDP system features simple operation and maintenance, with modest capital investment.

It can be equipped with industrial residual heat or other thermal fluid as heat sources. Dried sludge does not need to be returned to the process, and the moisture content of the outlet sludge can be adjusted via the shaft rotational speed.

The system can achieve either semi-drying or full drying. Fully dried sludge typically consists of particles smaller than 10 mm, while semi-dried sludge is generally          loose and clumpy. It is widely applicable to the reduction treatment of municipal and industrial sludge.

Product Features

Efficient reduction

Mechanically dewatered sludge with a moisture content of 75–85% can be thermally dried to 10%, achieving a mass reduction of over 80% and significantly reducing transportation and disposal costs.

Adjustable Load

Transmission and feeding motors feature stepless speed control, enabling continuous feeding of sludge with moisture content ranging from 60% to 85% and producing dried sludge with 10–40% moisture content. The system offers excellent adaptability, operational flexibility, and high drying efficiency.

Eco-Friendly & Low-Odor

No large volumes of air are required for heat transfer, reducing dust generation and greenhouse gas emissions. Equipped with dust removal and deodorization systems to meet applicable emission requirements.
