Incineration slag refers to the solid waste generated in the process of Incineration. As the temperature of Incineration is higher than 800 ℃, the slag contains a lot of inorganic substances, such as minerals, metals, etc. These substances have certain hazards to the environment and human health. Therefore, it is very necessary to treat Incineration slag.
At present, the main methods of Incineration slag treatment include dry wet separation process, magnetic separation process, screening process, etc. Among them, the dry wet separation process is a relatively mature treatment method, which can separate the organic and inorganic substances in the Incineration slag, so as to reduce the harm to the environment and human health.
The principle of the dry and wet separation process is to separate the organic and inorganic substances in the Incineration slag by using the dry and wet separation equipment. The specific operation steps are as follows:
Step 1: send the Incineration slag to the dry and wet separation equipment through the conveyor belt.
Step 2: separate large inorganic substances from Incineration slag through vibrating screen.
Step 3: The light organic matter in the Incineration slag is separated by the wind separator.
Step 4: separate the heavy organics in the Incineration slag through the wet separator.
Through the above four steps, the organic and inorganic substances in the Incineration slag can be separated to reduce the harm to the environment and human health.
The advantage of dry wet separation process is good treatment effect, which can separate organics and inorganic substances in Incineration slag, so as to reduce the harm to environment and human health. At the same time, the dry wet separation process can also make use of organics as resources, such as Organic fertilizer. The disadvantage is that the equipment cost is high and requires a large amount of investment for construction.
In a word, the dry and wet separation process of Incineration slag is a relatively mature treatment method, which can separate organic and inorganic substances in Incineration slag, so as to reduce the harm to the environment and human health. In future development, we need to further improve the dry wet separation process, improve its treatment efficiency and resource utilization, in order to better protect the environment and human health.
