Treatment of Slag in Incineration Power Plant

Treatment of Slag in Incineration Power Plant

Incineration power plant is a kind of equipment that burns garbage to generate electricity. During this process, a large amount of slag will be generated, and if not properly treated, it will cause pollution to the environment. This article will introduce the treatment method of Incineration power plant slag, and how to convert slag into resources.

1、 Generation of slag in Incineration power plant

Incineration power plant is a kind of equipment that burns garbage to generate electricity. During this process, garbage undergoes high-temperature combustion, producing a large amount of slag. Slag is mainly composed of minerals and glass, with characteristics such as high temperature, high alkalinity, high acidity, and high corrosiveness. If not properly treated, it can cause environmental pollution.

2、 Classification of slag in Incineration power plant

The slag of Incineration power plant can be divided into two types: fly ash and bottom slag. Fly ash is a granular substance formed during combustion in the furnace due to high combustion temperature, usually discharged directly into the atmosphere. Bottom slag is a solid substance that accumulates at the bottom of the furnace and usually requires treatment.

3、 Treatment Method of Slag in Incineration Power Plant

There are many ways to treat the slag of Incineration power plant, including landfill, recycling, cement concrete production, etc. The following will provide a detailed introduction to each processing method.

1. Landfill

Landfill is a method of directly burying Incineration power plant slag. The advantages of this method are simplicity and low cost, but it causes significant environmental pollution. Landfilling can cause harmful substances in slag to seep into groundwater and soil, causing long-term environmental pollution.

2. Recycling

Recycling is a method of converting Incineration power plant slag into resources. Slag contains a large amount of inorganic substances and can be used to produce building materials such as cement, bricks, and road materials. The advantage of this method is that it reduces environmental pollution while also reducing the cost of building materials.

3. Cement concrete production

Cement concrete production is a method to produce building materials by adding slag from Incineration power plant to cement concrete. This method can effectively utilize slag while also improving the strength and durability of concrete.

4、 Treatment process of slag in Incineration power plant

The slag treatment process of Incineration power plant includes collection, transportation, treatment and recycling. The following will provide a detailed introduction to the operational steps of each link.

1. Collection

The collection of slag from Incineration power plants requires special equipment. The collection equipment usually includes slag conveyors, slag silos, slag trucks, etc. During the collection process, attention should be paid to the insulation of the slag to avoid premature cooling during transportation.

2. Transportation

The transportation of slag is usually carried out using specialized slag trucks. During transportation, it is necessary to pay attention to avoiding the scattering and leakage of furnace slag to avoid environmental pollution.

3. Handling

The treatment of slag in Incineration power plant needs to choose different methods according to the specific situation. If the method of landfill is adopted, it is necessary to select a suitable landfill site and carry out landfill according to relevant regulations. If the method of recycling is adopted, it is necessary to screen, clean, dry and other processes of slag before recycling.

4. Recycling

The recovery and utilization of slag from Incineration power plants need to choose different methods according to specific conditions. If the method of producing building materials is used, it is necessary to process and mix the slag before production. If other recycling methods are used, corresponding treatment is required.

V. Precautions for slag treatment in Incineration power plant

The following points shall be paid attention to in the slag treatment of Incineration power plant:

1. Slag should be disposed of in a timely manner to avoid pollution to the environment.

2. The treatment method for slag should be selected according to the specific situation to avoid wasting resources.

3. The treatment of slag should comply with relevant laws, regulations, and standards.

4. The treatment of slag should pay attention to protecting the environment and human health.

6、 Conclusion

The treatment of slag in Incineration power plant is an important environmental protection work. By properly treating slag, it can reduce environmental pollution and also convert it into resources, achieving resource recycling. In the process of handling slag, it is necessary to pay attention to protecting the environment and human health, and comply with relevant laws, regulations, and standards.
