1.Project Background
With the acceleration of global urbanization, the treatment and disposal of municipal sludge has become one of the key challenges in environmental protection and sustainable development. In response to this issue, an overseas municipal sludge dewatering project has adopted the GNLW364 sludge dewatering centrifuges produced by GN Solids Control to improve sludge dewatering efficiency, reduce moisture content, and achieve the goals of resource utilization, reduction, and harmlessness of sludge.
2.Equipment Overview
Model and Quantity: GNLW364 sludge dewatering centrifuge, totaling 3 units.
Design Characteristics:
Single-unit Processing Capacity: 35m³/h
Design Critical Speed: 3900RPM
Regular Speed Range: 0-3200RPM
Critical Separation Factor: 3063G
Particle Separation Diameter: 2-5μm
Differential Gearbox Torque: 3500N.M
Main Motor Power: 37KW
The drum material is duplex stainless steel SS2305, outperforming industry standards.
The centrifugal casting process ensures a uniform drum texture with excellent dynamic balance performance.
The discharge port and the outlet of the screw conveyor are embedded with tungsten carbide hard alloy sleeves, providing high wear resistance.
The screw conveyor is embedded with wear-resistant alloy plates, ensuring a long service life and reducing maintenance frequency.
Controlled by a PLC panel, real-time monitoring of equipment status is possible.
3. Application Scenarios
The GNLW364 sludge dewatering centrifuges in this project are widely used in urban sewage treatment plants, industrial wastewater treatment plants, and other facilities. Through efficient centrifugal dehydration technology, the centrifuges quickly remove water from the sludge, reducing the moisture content and facilitating subsequent treatment and disposal.
4.Project Benefits
Improved Dewatering Efficiency:
The GNLW364 sludge dewatering centrifuges utilize advanced centrifugal dehydration technology to effectively remove water from sludge, significantly improving dewatering efficiency.
Energy Conservation and Environmental Protection:
No chemical agents are required during the dehydration process, reducing environmental pollution. Additionally, the equipment has low energy consumption, promoting energy conservation and emission reduction.
Easy Operation:
The equipment features an automated control system, simplifying operation and reducing labor costs.
Strong Adaptability:
The equipment is suitable for processing different types of sludge, demonstrating strong adaptability.
5. Conclusion
By adopting the GNLW364 sludge dewatering centrifuges produced by GN Solids Control, the overseas municipal sludge dewatering project has achieved the goals of efficient, environmentally friendly, and energy-saving sludge treatment. This not only contributes to improving local environmental quality but also facilitates the sustainable development of the city.
