With the acceleration of urbanization, the amount of municipal solid waste is increasing year by year. How to achieve waste reduction, resource utilization, and harmless treatment has become an important issue. A municipal solid waste Solid Waste Management resource utilization, through scientific sorting and processing, transforms waste into usable resources, and is a key link in realizing a circular economy.
Guoxin Machinery briefly introduces its core design points:
I. Main Components of the Production Line
1. Pre-treatment System
After the waste enters the plant, it undergoes pre-treatment, including coarse shredding, uniform feeding, and deodorization. Pre-treatment can improve the efficiency of subsequent sorting and reduce environmental pollution.
2. Intelligent Sorting System
This is the core component of the production line, typically including:
– Magnetic separator: Separates ferrous metals
– Eddy current separator: Separates non-ferrous metals
– Air separator: Separates lightweight materials (such as plastic film) based on density differences
– Optical sorting equipment: Precisely sorts different materials such as plastics and glass through image recognition
– Screening equipment: Grades waste by particle size
3. Resource Recovery Unit
– Organic waste can be used for anaerobic fermentation to produce biogas or aerobic composting
– Renewable resources such as plastics, metals, and paper are packaged and sold externally
– High-calorific-value waste can be made into derived fuel (RDF)
4. Intelligent Control and Environmental Protection System
A centralized control platform enables full-process monitoring, coupled with dust removal, deodorization, and wastewater treatment systems to ensure environmental compliance.
II. Solid Waste Management Design Considerations
1. Flexibility and Modularization
The production line design should adapt to regional differences and seasonal variations in waste composition, adopting a modular design to facilitate adjustments to the process sequence or the addition or removal of equipment.
2. Automation and Intelligentization
Increase the application rate of mechanical sorting and intelligent identification technologies to reduce the need for manual sorting and improve sorting purity and efficiency.
3. Environmental Protection Throughout the Process
From feeding, crushing, sorting, to discharge, each stage should be equipped with dust collection and exhaust gas treatment devices to avoid secondary pollution.
4. Safety and Convenient Maintenance
The equipment layout should reserve safety passages and maintenance space. Key components should be easy to inspect and replace to ensure continuous and stable operation of the production line.
III. Conclusion
The core design of a municipal solid waste Solid Waste Management resource recovery lies in efficient sorting, high-value resource utilization, and environmental control throughout the entire process. By rationally configuring sorting modules, introducing intelligent technologies, and adhering to green operation, waste can be transformed from “waste end” to “resource end,” contributing to sustainable urban development.
