Separation process of waste power plant slag

Separation process of waste power plant slag

With the acceleration of urbanization, the amount of urban waste continues to increase. In garbage treatment, slag is a common waste. In garbage power plants, slag is generated by high-temperature combustion of waste. The production of slag is very large, and if not treated, it will cause great pollution to the environment. Therefore, the separation process of slag has become crucial.

The main purpose of the slag sorting process is to separate useful substances from the slag, reduce the amount of waste, and at the same time reduce environmental pollution. The following will introduce the operating steps of the slag sorting process for garbage power plants.

1、 Collection and treatment of slag

In garbage power plants, slag is generated by high-temperature combustion of waste. The production of slag is very large and requires collection and treatment. Firstly, the slag will be transported to the slag treatment area through conveyor belts. In the slag treatment area, the slag will be dumped into the slag pit for preliminary treatment. The purpose of preliminary treatment is to separate large blocks of material from the slag for subsequent treatment.

2、 Screening and magnetic separation of slag

After preliminary treatment, the slag will be transported to the screening machine for screening. The purpose of screening is to separate large blocks of materials such as stones and bricks from the slag for subsequent processing. After screening, the slag will be transported to the magnetic separator for magnetic separation. The purpose of magnetic separation is to separate the metal substances in the slag for subsequent treatment.

III. Gravity and dry separation of slag

After magnetic separation, the slag will be transported to the gravity separator for gravity separation. The purpose of re selection is to separate useful substances such as steel bars, concrete, etc. from the slag. After re selection, the slag will be transported to the dry selection machine for dry selection. The purpose of dry selection is to further separate useful substances from the slag for subsequent treatment.

IV. Reuse of slag

After the above sorting process, the useful substances in the slag have been separated. These useful substances can be reused, such as steel bars that can be recycled, and concrete that can be crushed and reused. These reused substances can reduce the amount of waste and reduce environmental pollution.

Summary:

The separation process of slag from a garbage power plant is a very important task. Through the slag sorting process, useful substances in the slag can be separated, reducing the amount of waste and reducing environmental pollution. In the sorting process, it is necessary to carry out operational steps such as slag collection and treatment, screening and magnetic separation, gravity separation and dry separation. Through these steps, useful substances in the slag can be separated and reused to reduce the amount of waste and reduce environmental pollution.
