With the development of economic globalization, people are paying more and more attention to air quality, and it is necessary for countries and regions to formulate strict environmental protection laws and regulations to limit the NOx content in industrial emissions. As a common equipment in industrial production, the NOx content in the exhaust gas of rotary kiln must reach the legal standard.
The application field of rotary furnace is very wide, whether it is cement production, iron and steel smelting, non-ferrous metal smelting, chemical industry, lithium battery material production, environmental protection and resource recovery, construction industry, etc., all need rotary furnace to provide continuous heat treatment process, but in this process, it will produce nitrogen oxide emissions. NOx is one of the main substances in the formation of acid rain and photochemical smog, which reacts with water molecules in the atmosphere to form nitric acid, resulting in the production of acid rain, causing damage to the environment and ecosystem. NOx is also an important substance in the formation of photochemical smog in the atmosphere. Under sunlight, NOx will react photochemically with VOCs to generate ozone (O₃) and other strong oxidizing substances such as peroxyacetyl nitrate (PAN), resulting in the formation of photochemical smog. It will also cause potential harm to human health, ecosystems and building materials, etc., and these environmental problems can be effectively reduced by reducing NOx emissions through denitrification equipment.
National and local governments have clear standards and requirements for the emission of air pollutants from industrial furnaces, and denitrification is an important means for furnaces to meet these environmental standards. With the development of environmental protection technology, denitrification technology has been very mature, including low nitrogen combustion technology, SNCR, SCR, etc., these technologies can effectively remove NOx from the flue gas emitted by rotary kilns.
Rotary furnace denitration, using Green Valley environmental protection SCR denitration system, with independent intellectual property rights and a number of invention patents, while accumulating a lot of experience, can ensure that the project design is reasonable, stable and reliable operation, can meet the latest national environmental requirements, ultra-low nitrogen oxide emissions and ammonia escape less than 3ppm requirements.
By installing denitration equipment, companies can effectively fulfill their commitment to environmental protection, while enhancing the public’s trust in the company and the company’s social responsibility image. By reducing nitrogen oxide emissions, companies may receive environmental subsidies or tax breaks from the government, which could bring economic benefits in the long run. Nox treatment is also part of a company’s social responsibility and helps build its sustainable development strategy.
