With the acceleration of technological iteration, e-waste such as used computers, mobile phones, and home appliances is growing explosively.
This type of waste contains heavy metals and toxic substances, which will pollute the environment if not handled properly. However, it also contains recyclable resources such as gold, silver, copper, aluminum, and plastics, which can be called “urban mines”. The development of an efficient and environmentally friendly E-waste Recycling System can not only solve pollution problems but also realize resource recycling, which is in line with the concepts of green development and circular economy. This solution focuses on the entire process of e-waste recycling to promote the sustainable development of the industry.
Solution Introduction
This e-waste recycling system targets various types of e-waste and achieves efficient resource recovery and environmental protection through multi-link collaboration, covering the complete process from pre-treatment to precise separation and recovery of metals and non-metals.
(I) Pre-treatment Link
Waste PCBs, circuit boards, etc., are sent to a heating machine and heated at 250°C to separate the electrical components.
(II) Crushing and Separation Link
Multi-stage crushing:
The separated materials enter a combination of a double-shaft shredder, a pulverizer, and a grinder. The double-shaft shredder first performs rough crushing to break the structure of e-waste; the pulverizer then conducts fine crushing; the grinder further refines the particle size (e.g., crushing circuit boards into small particles conducive to metal separation). This ensures the subsequent separation effect and lays a solid foundation for the core separation process of the system.
Separation process:
Magnetic separation: Magnetic separation equipment is used to separate ferromagnetic metals, realizing the initial recovery of iron-based metals.
Airflow separation: Utilizing the density difference of materials, light plastics are separated from heavy metal particles, glass, etc., by airflow, laying the groundwork for fine separation and undertaking the initial screening of materials in the system.
Electrostatic separation: For non-ferrous metals such as copper and aluminum, and plastics, they are accurately separated by an electrostatic separator based on the difference in electrostatic adsorption characteristics (e.g., efficiently separating copper foil from circuit boards), which improves the recovery purity and is a key process for the system to achieve high-purity resource recovery.
Dust removal: In dust-producing links such as crushing and separation, pulse dust removal technology is used to efficiently collect dust (with a dust removal efficiency of over 99%), which is discharged up to standard after purification, forming a solid environmental protection barrier for the system.
Materials to be Processed
The types of e-waste that can be processed by this e-waste recycling system include but are not limited to:
- Consumer electronics: Used mobile phones, laptops, tablets, smart watches, etc.
- Home appliances: Scrap refrigerators, TVs, washing machines, air conditioners, microwave ovens, etc.
- Office electronics: Used printers, copiers, servers, routers, PCBs, etc.
Equipment Advantages
Efficient recovery
The recovery rate of metals such as copper, aluminum, and precious metals is high (copper recovery rate exceeds 98%, and the purity of precious metals reaches 99.9%), which deeply taps the resource value of e-waste and demonstrates the regeneration capability of the system.
Environmental compliance
The entire process of the e-waste recycling system is equipped with environmental protection equipment, and the emission of dust and waste gas strictly meets standards (e.g., dust emission ≤ 10mg/m³), avoiding secondary pollution and ensuring the green operation of the system.
Flexible adaptation
Equipment and parameters can be adjusted according to the processing scale (hourly processing capacity can be flexibly customized from several tons to dozens of tons) and waste types to meet diverse needs, reflecting the flexible deployment of the system.
Energy saving and cost reduction
The unit energy consumption is only about 3/5 of similar products, and the long-term operation cost is controllable, highlighting the economic advantages of the system.
