With the acceleration of industrialization, the development of the power industry is also becoming increasingly rapid. During the power generation process, slag is an inevitable product. If left untreated, these slag may cause significant environmental pollution. So, how to deal with incineration of power plant slag? This article will introduce some common processing methods for everyone.
1. Landfill method
The landfill method is a common method of slag treatment. The principle of this method is to transport the slag to the landfill and then bury it. The advantages of landfill method are low cost and simple operation, but the disadvantage is also obvious, which is that it has a significant impact on the environment. During the landfill process, a large amount of leachate and gases are generated, which may pollute groundwater and the atmospheric environment.
II. Crushing and recycling method
The crushing and recycling method is a relatively environmentally friendly slag treatment method. The principle of this method is to crush the slag and then recycle it. The advantage of the crushing and recycling method is that it can reduce the volume of slag, reduce the cost of landfill, and also recycle and utilize the metals and minerals in it. However, this method also has a drawback, which is that it requires a significant investment in equipment and labor costs.
3、 Incineration method
Incineration method is a method of high-temperature treatment of slag. The principle of this method is to put the slag into a high-temperature furnace for combustion, and then treat the generated ash. The advantage of incineration method is that it can completely burn the slag, reduce environmental pollution, and also recover and utilize the energy inside. However, the drawback of this method is also evident, which requires a significant investment in energy and equipment costs.
4、 Water quenching method
Water quenching method is a method of rapid cooling of furnace slag. The principle of this method is to pour the slag into water for cooling, and then treat the generated solid slag. The advantage of water quenching method is that it can quickly cool the slag, reduce environmental pollution, and also recycle the metals and minerals in it. However, the drawback of this method is also evident, which requires a large amount of water resources and treatment equipment.
In summary, there are many methods for treating incineration of power plant slag. Which method to choose needs to be evaluated based on the actual situation. If the cost is relatively low, the landfill method can be chosen; If you want to recycle the metals and minerals in the slag, you can choose the crushing recovery method; If you want to reduce environmental pollution, you can choose incineration or water quenching method. No matter which method is chosen, attention should be paid to environmental issues to ensure that the treated slag does not cause secondary pollution to the environment.How to dispose of slag from incineration power plants
