Utilization of slag from large-scale garbage power generation

With the acceleration of urbanization, the problem of garbage has become increasingly prominent, and how to effectively utilize garbage has become an urgent problem to be solved. The utilization of large-scale waste power generation slag is a feasible solution. This article will provide a detailed introduction to the operating steps and advantages of large-scale waste power generation slag utilization.

1、 What is the utilization of large-scale waste power generation slag?

The utilization of large-scale waste power generation slag refers to the process of reusing the slag generated in the waste power generation furnace. The waste power generation slag is mainly composed of inorganic substances, including glass, ceramics, metals, etc. The proportion of these substances in the slag varies with the type of waste and combustion conditions.

2、 Operating Steps for Utilizing Slag from Large Garbage Power Plants

1. Preliminary treatment of slag

Firstly, it is necessary to perform preliminary treatment on the slag to remove impurities and harmful substances. This process can be carried out through screening, magnetic separation, washing, and other methods. The treated slag can be used for road construction, landfill coverage, etc.

2. Reuse of slag

The slag after preliminary treatment can also be reused. At present, there are several main ways of reuse:

(1) Cement production

The inorganic substances in slag can be used in cement production as one of the raw materials for cement. Silicate, Aluminate and other substances in the slag can be burned together with limestone and other raw materials to produce cement clinker, and then ground to produce cement.

(2) Pavement construction

Materials such as glass and ceramics in slag can be used in road construction. These substances have high hardness and wear resistance, which can increase the durability and stability of the road surface.

(3) Brick production

The metal in slag can be used in brick production. These metals can increase the strength and hardness of bricks, while also reducing their weight.

3、 Advantages of Utilizing Slag from Large Garbage Power Plants

1. Resource reuse

The utilization of large-scale waste power generation slag can reuse the inorganic substances in waste, reducing the consumption of natural resources.

2. Environmental protection and energy conservation

The utilization of large-scale waste power generation slag can effectively treat waste and reduce environmental pollution caused by waste. At the same time, garbage power plants can also use garbage to generate energy, achieving resource conservation and utilization.

3. Economic benefits

The utilization of large-scale waste power generation slag can convert waste into resources, creating economic benefits. At the same time, garbage power plants can also generate electricity, providing energy for society.

4、 Conclusion

The utilization of large-scale waste power generation slag is a feasible waste treatment plan. By preliminary treatment and reuse of slag, the inorganic substances in waste can be effectively utilized, achieving resource reuse and environmental protection and energy conservation. At the same time, the utilization of large-scale waste power generation slag can also create economic benefits and provide energy for society.
