Slag metal sorting of Incineration power plant

With the acceleration of urbanization, the problem of urban waste has become increasingly prominent. Incineration power plant, as a way to treat urban garbage, has also caused people's concern about the slag problem. The slag contains a large amount of metal, and if it cannot be effectively recycled, it will not only pollute the environment but also waste resources. Therefore, the research and application of slag metal sorting technology is of great significance.

1、 The significance of slag metal sorting

Slag contains a large amount of metals, including iron, copper, aluminum, zinc, etc. If these metals are effectively recycled, they can not only save resources but also reduce environmental pollution. If discharged directly without treatment, it will cause serious pollution to the environment such as soil and water sources. Therefore, the significance of slag metal sorting lies in:

1. Resource saving: The metal in the slag can be effectively recycled and utilized, saving resources.

3. Increase economic benefits: The metals in the slag can be effectively recycled and utilized, increasing economic benefits.

At present, there are several main methods for sorting slag metal:

1. Manual sorting: Manual sorting is the earliest and simplest sorting method, but due to low efficiency and high labor costs, it has gradually been phased out.

2. Traditional mechanical sorting: Traditional mechanical sorting mainly uses methods such as vibrating screens and airflow separation, but due to poor sorting performance, it is difficult to achieve automated control and has gradually been phased out.

3. Optical sorting: Optical sorting is a sorting technology based on optical characteristics, which can efficiently and accurately sort metals. This technology has been widely used, but due to its high cost, further cost reduction is needed.

4. Induction sorting: Induction sorting is a sorting technology based on the principle of electromagnetic induction, which can efficiently and accurately sort metals. This technology has been widely applied, but further optimization is needed due to the influence of metal types and shapes on the sorting effect.

3、 Application of slag metal sorting

The slag metal sorting technology has been widely applied, mainly in the following fields:

1. Incineration power plant: Incineration power plant is the main application field of slag metal sorting technology, which can sort the metals in the slag efficiently and accurately, and realize the effective recovery and utilization of resources.

2. Metallurgical industry: The metallurgical industry is another application field of slag metal sorting technology, which can sort the waste slag generated in the metallurgical process and achieve effective resource recovery and utilization.

3. Urban construction: Slag metal sorting technology can sort waste building materials generated in urban construction, achieving effective resource recycling and utilization.

Future Development of Slag Metal Sorting

In the future development of slag metal sorting technology, further optimization and innovation are needed. Specifically, research needs to be conducted from the following aspects:

1. Technological innovation: It is necessary to develop more efficient and accurate sorting technologies, reduce costs, and improve sorting efficiency.

3. Environmental requirements: It is necessary to further improve environmental requirements and reduce pollution to the environment.

In summary, slag metal sorting technology is a significant technology that can achieve effective resource recycling, reduce environmental pollution, and increase economic benefits. In the future development, it is necessary to further optimize and innovate, realize more efficient and accurate sorting technology, realize automatic control, improve environmental protection requirements, and make greater contributions to urban waste treatment and Recycling.
