In today’s economic globalization, people’s awareness of environmental protection is increasing day by day, and the control of pollutant discharge in the industrial production process becomes particularly important. As an important equipment in iron and steel industry, the emission of nitrogen oxides (NOx) in the production process of electric arc furnace needs to be solved.
The production of NOx in the process of steel making by electric arc furnace is a complex physical and chemical process, which involves many factors such as high temperature, raw material characteristics, furnace atmosphere and operating conditions. Electric arc furnace in the process of steelmaking will produce a large number of nitrogen oxides, these gases have potential harm to the environment and human health, if the electric arc furnace uses fuel (such as coal, natural gas, etc.) as an auxiliary energy, the nitrogen compounds in the fuel will also decompose in the combustion process to produce NOx. Therefore, denitrification of electric arc furnaces is not only a requirement of environmental regulations, but also the embodiment of corporate social responsibility.
SCR system provided by Green Valley Environmental Protection is an efficient flue gas denitrification technology, which does not need to modify the main arc furnace, directly treat the tail gas, and has no impact on the main arc furnace. Through a certain temperature and catalysis, the SCR system can reduce NOx to harmless nitrogen and water vapor, and achieve effective emission of nitrogen oxides. In the field of ultra-low emission of nitrogen oxides, it realizes the functions of compact structure design, intelligent, precise injection, forecast alarm, data collection and management, remote control, online transmission, etc., which can ensure that the ammonia escape data is less than 3ppm while achieving ultra-low emission, and has a strong comprehensive competitiveness.
