Garbage is an inevitable product generated in human life, and how to effectively treat garbage has become a global challenge. Incineration of garbage and slag treatment is a common method of garbage treatment, which can refine garbage into slag, thereby reducing the impact of garbage on the environment. This article will introduce the process of treating waste incineration slag to help readers better understand this waste treatment method.
1、 Preparation before slag treatment
Before proceeding with the treatment of incineration waste and slag, some preparatory work needs to be done. Firstly, it is necessary to classify the garbage and separate recyclables, harmful substances, and other waste. Secondly, it is necessary to conduct preliminary treatment on the garbage and break up Bulky waste to facilitate subsequent treatment. Finally, the waste needs to be sent to the incinerator for treatment.
2、 Incineration waste slag treatment process
1. Garbage feeding
After the garbage enters the incinerator, it needs to be preheated first. During the preheating process, the moisture in the garbage will be evaporated, and the organic matter in the garbage can also be decomposed into easily combustible gases.
2. Combustion process
After preheating treatment, the garbage will enter the combustion chamber for combustion. During the combustion process, the organic matter in the garbage will be burned into carbon dioxide and water vapor, while also generating a large amount of heat energy. These thermal energy can be used to generate steam, which drives a generator to generate electricity.
3. Slag treatment
During the combustion process, the inorganic substances in the garbage are refined into slag. Slag is a black substance that can be used to pave roads, make bricks, and so on. During the slag treatment process, it is necessary to cool and screen the slag to remove impurities.
4. Smoke treatment
During the process of burning garbage and slag, a large amount of smoke is generated. These flue gases contain a large amount of harmful substances such as sulfur dioxide and nitrogen oxides, which can cause great harm to the environment if directly discharged into the atmosphere. Therefore, in the process of flue gas treatment, it is necessary to carry out dust removal, desulfurization, denitrification and other treatments on the flue gas to ensure that the discharged flue gas meets environmental standards.
Incineration of garbage and slag treatment is a common method of garbage treatment, which can refine garbage into slag, thereby reducing the impact of garbage on the environment. Before carrying out the incineration of garbage and slag treatment, some preparatory work needs to be done, such as sorting and preliminary treatment of garbage. In the process of incineration of garbage and slag, steps such as garbage feeding, combustion, slag treatment, and flue gas treatment are required. Through the introduction of these steps, it is believed that readers have gained a deeper understanding of the incineration slag treatment process.Incineration waste slag treatment process
