Utilization of Incineration slag

Incineration slag refers to the solid waste generated in the process of Incineration, usually including slag, ash, etc. These wastes are often regarded as garbage and are directly buried or dumped into the ocean, which not only pollutes the environment but also wastes a large amount of resources. However, Incineration slag is actually a valuable resource, which can be converted into new materials through reasonable utilization and bring more value to the society.

Types of Incineration slag

There are many kinds of Incineration slag, mainly including slag, ash, limestone slag, etc. Among them, slag refers to a solid waste formed during the incineration process due to the presence of metal substances in the garbage, which are oxidized and decomposed at high temperatures. Ash refers to a type of solid waste formed during the incineration process due to the presence of organic substances in the garbage, which are decomposed at high temperatures. Limestone slag refers to a solid waste formed during the incineration process due to the decomposition of minerals such as limestone in the garbage at high temperatures.

Utilization of Incineration slag

Incineration slag can be used in many ways, mainly including the following:

1. Building materials

Incineration slag can be used to produce building materials, such as bricks, tiles, concrete, etc. Among them, slag can be used to produce high-strength concrete, and ash can be used to produce building materials such as gypsum boards.

2. Road Foundation Materials

Incineration slag can be used to produce road basic materials, such as asphalt mixture, cement concrete, etc. Among them, slag can be used for producing road base, roadbed, etc., and ash can be used for producing road subbase.

3. Energy utilization

Incineration slag can be used to produce energy, such as heat energy, electric energy, etc. Among them, slag can be used to produce high-temperature thermal energy, and ash can be used to produce electrical energy.

4. Agricultural fertilizers

Incineration slag can be used to produce agricultural fertilizer, such as Organic fertilizer, inorganic fertilizer, etc. Among them, slag can be used to produce inorganic fertilizer and ash can be used to produce Organic fertilizer.

Utilization steps of Incineration slag

The utilization steps of Incineration slag mainly include the following aspects:

1. Collection and classification

First, it is necessary to collect and classify Incineration slag. During collection, attention shall be paid to classification, and different types of Incineration slag shall be separated for subsequent treatment and utilization.

2. Handling and processing

Incineration slag needs to be treated and processed for subsequent use. The methods of processing and processing include grinding, screening, heat treatment, etc. Among them, grinding and screening are to finely crush and separate the Incineration slag for subsequent use. Heat treatment refers to high-temperature treatment of Incineration slag to change its physical and chemical properties for subsequent use.

3. Preparation of new materials

After treatment and processing, Incineration slag can be used to prepare new materials. The methods of preparing new materials include concrete, road foundation materials, fertilizers, etc.

4. Application

The prepared new materials can be applied in fields such as architecture, roads, agriculture, etc., bringing more value to society.

conclusion

Incineration slag is a valuable resource, which can be transformed into new materials through reasonable utilization and bring more value to the society. The utilization steps of Incineration slag mainly include collection and classification, treatment and processing, preparation of new materials, application, etc. In the future, we should pay more attention to the utilization of Incineration slag and make greater contributions to environmental protection and resource conservation.
