Slag Treatment Technology for Garbage Power Plants

Slag Treatment Technology for Garbage Power Plants

With the acceleration of urbanization, the production of urban garbage has been increasing year by year, and how to effectively treat garbage has become an urgent problem to be solved in various cities. Garbage power plants are currently a common method of garbage disposal, but they produce a large amount of slag during the garbage power generation process. If left untreated, it can cause serious environmental pollution. Therefore, the slag treatment technology of garbage power plants is particularly important.

1、 Composition and characteristics of slag from garbage power plants

Before understanding the slag treatment technology of garbage power plants, we need to first understand the composition and characteristics of garbage power plant slag. The slag of garbage power plant is mainly composed of slag, ash slag, semi coke slag, coal slag, etc. It is characterized by large hardness, coarse Granularity, high moisture content, and difficult to treat.

2、 Slag Treatment Technology for Garbage Power Plants

1. Magnetic separation method

Magnetic separation method is a common slag treatment technology for garbage power plants, which uses magnetic substances to separate the slag. Firstly, the slag is crushed and separated by a magnetic separator. Magnetic substances are adsorbed on the magnetic poles, while non magnetic substances are eliminated. The slag treated by this method has good quality and can be used in fields such as road laying.

2. Water quenching method

The water quenching method is a method of rapidly cooling the slag, which can effectively reduce the temperature of the slag and reduce the pollution of the slag to the environment. This method requires the slag to be crushed and cooled by water quenching equipment, followed by screening and magnetic separation to obtain high-quality slag.

3. Crushing method

Crushing method is a method of finely crushing furnace slag, which can make the Granularity of furnace slag more uniform and facilitate subsequent treatment. This method requires the slag to be crushed and crushed, and then separated through methods such as screening and magnetic separation to ultimately obtain high-quality slag.

3、 Advantages of slag treatment technology in garbage power plants

The slag treatment technology of garbage power plants has the following advantages:

1. Environmental protection: The use of waste power plant slag treatment technology can effectively reduce the pollution of slag to the environment.

2. Energy saving: During the slag treatment process, a portion of energy can be recovered, thereby achieving the goal of energy conservation.

3. Resource utilization: The treated slag can be used in fields such as road laying to achieve resource utilization.

4、 Conclusion

The research and application of slag treatment technology in garbage power plants are of great significance for urban garbage treatment and environmental protection. In the future, we need to continuously explore and innovate, search for more efficient and environmentally friendly slag treatment technologies, and make greater contributions to urban waste treatment and environmental protection.
