Blast furnace plays a vital role in our lives, is an indispensable important equipment in the process of steel production, blast furnace can provide a large amount of iron and steel, for the development of society has made an important contribution, mainly used in construction, ships, machinery, automobiles and so on. In addition, can also produce a lot of energy, mainly gas, coke, etc., these energy can not only meet the needs of industrial production development, but also can be used for power generation, heating, etc., for our lives to provide convenience at the same time, but also for us to create employment opportunities, further promote the development of the global economy, blast furnace achievements in our lives, is an indispensable part.
However, the blast furnace will produce a lot of waste gas and waste water in the production process, which contains a large number of harmful substances, will produce a large number of nitrogen oxides, carbon monoxide, sulfur dioxide, etc., causing serious pollution to our lives and the environment. It will also produce a lot of iron slag, slag, these wastes are not handled in time, it will cause pollution to our environment.
The production of nitrogen oxides will form particulate matter and ozone, which will have a negative impact on human health and the ecological environment. It is very important to effectively control the emission of nitrogen oxides and further improve air quality. Nitrogen oxides as one of the air pollutants of industrial furnaces, the control of flue gas emission can not only reduce the generation of pollution, but also enhance the image of corporate social responsibility, enhance the public’s trust and support for enterprises, and the effective control of nitrogen oxides helps to promote the development of enterprise technology and enhance the public’s trust and support for enterprises. Help to enhance its green production and sustainable development strength, enhance the competitiveness of enterprises.
Blast furnace nitrogen oxide treatment is to control, recover or use nitrogen oxides NOx in the exhaust gas, the blast furnace in the combustion process, will produce nitrogen oxides, improve combustion efficiency, is conducive to control nitrogen oxide emissions, reduce environmental pollution, effectively improve energy utilization, and promote sustainable development. By optimizing the burner design, such as using multi-layer burners or thick and thin burners, the generation of thermal nitrogen oxides can be effectively reduced.
The low nitrogen transformation of blast furnace can also improve the production efficiency and economic benefit of blast furnace. Using SCR denitrification system independently developed by Guangdong Green Valley Environmental Protection Technology Co., LTD., the catalyst reduces nitrogen oxides to nitrogen and water under low temperature conditions, and the ultra-low emission of nitrogen oxides and ammonia escape meet the national environmental protection requirements, less than 3ppm. Reduce emissions of harmful substances such as sulfur dioxide and nitrogen oxides, thereby improving air quality and protecting the environment.
