A garbage power plant is a facility for treating urban waste, which converts waste into electricity and heat energy by classifying, compressing, and incinerating it. In the process of Incineration, a large amount of slag will be generated, which will not only occupy the site of garbage power plant, but also cause environmental pollution. Therefore, how to handle these slag has become a problem that garbage power plants must solve.
The process of burning slag in garbage power plant is a method to treat the slag generated from Incineration. This method can classify, separate, recycle, and utilize slag to reduce environmental pollution and resource waste. The following will provide a detailed introduction to the operation steps of the method for burning slag in a garbage power plant.
1、 Classification of slag
In the process of Incineration, the slag is mainly divided into two types: heavy slag and light slag. Heavy slag refers to slag with high density, usually containing high metal content such as iron and aluminum. Light slag refers to slag with lower density, usually containing higher inorganic salts and organic substances. In the classification process of slag, it is necessary to separate heavy and light slag.
2、 Separation of slag
The separation of slag refers to the separation of heavy and light slag for subsequent treatment. In the separation process of slag, physical separation methods are usually used, such as gravity separation, magnetic separation, screening, etc. Among them, gravity separation refers to the use of gravity to separate heavy and light slag. Magnetic separation refers to the use of magnetic force to separate heavy slag containing metals. Sieving is the use of a sieve to separate slag of different sizes.
III. Recovery and utilization of slag
In the process of slag recovery and utilization, various methods such as physical, chemical, and biological methods are usually used. Among them, physical methods mainly refer to the utilization of the physical properties of furnace slag for recycling and utilization, such as utilizing the metal content of heavy furnace slag for recycling and utilization; Chemical methods mainly refer to the use of chemical reactions to convert slag, such as using elements such as calcium and magnesium in slag to prepare cement; Biological methods mainly refer to the use of microorganisms and other organisms to treat slag, such as using microorganisms to decompose organic substances in the slag.
4、 Treatment of slag
In the process of slag treatment, various methods such as physical, chemical, and biological methods are usually used. Among them, physical methods mainly refer to the use of the physical properties of slag for treatment, such as using the density of slag for landfill; Chemical methods mainly refer to the use of chemical reactions to convert slag, such as using elements such as calcium and magnesium in slag to prepare cement; Biological methods mainly refer to the use of microorganisms and other organisms to treat slag, such as using microorganisms to decompose organic substances in the slag.
In a word, the process of burning slag in garbage power plant is a method to treat the slag generated from Incineration. In the process of slag treatment, multiple processes such as classification, separation, recycling, and utilization of slag are required to achieve the goal of reducing environmental pollution and resource waste caused by slag.
