Incineration slag refers to a kind of solid waste generated in the process of Incineration, which is formed after the inorganic substances in the waste are burned at high temperature. Incineration slag contains a large number of inorganic substances, such as iron oxide, aluminum oxide, Calcium oxide and so on, which have high resource utilization value. This paper will introduce the resource utilization method and operation steps of Incineration slag.
1、 Resource utilization method of Incineration slag
1. Grind into powder
The Incineration slag is ground into powder, which can be used to manufacture cement, concrete and other building materials. The grinded Incineration slag has high activity, which can improve the strength and durability of building materials.
2. Extract metals such as iron and aluminum
Incineration slag contains a large amount of iron, aluminum and other metals, which can be recycled by extraction. There are various methods for extracting metals such as iron and aluminum, such as magnetic separation and leaching.
3. Manufacturing ceramic materials
Incineration slag contains a large amount of alumina, silica and other substances, which can be used to manufacture ceramic materials. The Incineration slag is grinded and screened, and then added with appropriate clay, quartz and other materials, which are made into ceramic materials through molding, drying, sintering and other processes.
4. Production of slag cement
Incineration slag contains a large amount of Calcium oxide, silicon oxide and other substances, which can be used to produce slag cement. The Incineration slag is ground and screened, and then appropriate gypsum, clinker and other materials are added to make slag cement through mixing, grinding, firing and other processes.
2、 Operation steps for resource utilization of Incineration slag
1. Collection of Incineration slag
Incineration slag is generated during incineration and needs to be collected. There are various collection methods, including mechanical collection and manual collection.
2. Grinding of Incineration slag
Grind the Incineration slag into powder. During the grinding process, attention should be paid to controlling the particle size for subsequent utilization.
3. Extraction of Incineration slag
If it is necessary to extract metals such as iron and aluminum, methods such as magnetic separation and leaching can be used. During the extraction process, attention should be paid to controlling reaction conditions to improve extraction efficiency.
4. Manufacture of Incineration slag
According to specific utilization requirements, Incineration slag can be manufactured into cement, concrete, ceramic materials and other products. During the manufacturing process, attention should be paid to controlling factors such as ratio and process conditions to ensure product quality.
5. Application of Incineration slag
The manufactured products will be used in construction, engineering and other fields to realize the resource utilization of Incineration slag. During the application process, attention should be paid to factors such as the effectiveness and safety of the product.
Incineration slag is a valuable resource. Through proper utilization, it can realize resource utilization and reduce environmental pollution. There are a variety of resource utilization methods for Incineration slag, which need to be selected according to the specific situation. In the process of resource utilization of Incineration slag, attention should be paid to the control of process conditions, product quality and other factors to improve utilization efficiency.Resource utilization of Incineration slag
