Utilization of Incineration furnace slag

With the acceleration of urbanization, the amount of urban waste is also constantly increasing. In order to solve the problem of garbage disposal, many cities have adopted Incineration technology. In the process of Incineration, in addition to generating heat energy, a large number of slag will also be generated. How to utilize these slag has become a problem worth exploring. This paper will analyze and discuss the composition and properties of Incineration furnace slag, the utilization way of slag, and the operation steps of slag utilization.

1、 Composition and properties of Incineration furnace slag

Incineration furnace slag refers to the solid waste generated in the process of Incineration. The composition and properties of slag are related to factors such as the type of garbage, incineration method, and temperature, generally including inorganic, organic, heavy metal, and other components. Among them, inorganic substances are the main components of slag, including oxides, silicates, chlorides, etc. The properties of slag also vary accordingly. Some slag has high stability and durability, while others are prone to expansion and dissolution.

2、 Utilization of slag

Slag is a valuable resource that can be utilized in various ways. The main utilization methods currently include the following:

1. Landfill: Landfill the slag in a landfill site to fill the land or cover the garbage.

2. Road construction: Using slag in road construction can be used for road reinforcement, roadbed filling, etc.

3. Cement production: Using slag in cement production can be used to replace some cement raw materials and reduce production costs.

4. Mineral Recycling: slag contains a certain amount of metal elements, which can be recycled by recycling.

5. Production of environmentally friendly building materials: Using slag in the production of environmentally friendly building materials can be made into building materials products such as bricks and tiles.

3、 Operating steps for slag utilization

The utilization of slag requires a series of operational steps, including the collection, treatment, and processing of slag. The following will provide a detailed introduction to the operating steps of slag utilization:

1. Slag collection: set collection equipment at the bottom of Incineration to collect the generated slag.

2. Slag treatment: Conduct preliminary treatment on the collected slag, including screening, magnetic separation, etc., to remove impurities and metals from it.

3. Slag processing: the processed slag can be grinded and crushed into products with different Granularity.

4. Utilization of slag: use the processed slag in landfill, road construction, cement production, mineral Recycling, environmental protection building materials production and other fields.

4、 Conclusion

The slag of Incineration furnace is a valuable resource, which can be used in many ways. In the process of utilizing slag, it is necessary to collect, process, and process the slag. The utilization of Incineration furnace slag can not only realize the recycling of resources, but also reduce the cost of garbage treatment, which is of great significance to environmental protection and sustainable development.
