As a core part of the global manufacturing industry, the foundry industry plays an indispensable role in economic development and technological progress. It plays a key role in economic development, technological innovation, industrial chain construction and job creation. As an important part of manufacturing industry, foundry industry will produce a lot of dust in the process of metal processing, which has a serious impact on the environment and human health. Effective dust treatment is very important to achieve sustainable industrial development and improve the industrial environment.

In the metal forming process of the foundry, after high temperature melting and pouring, inevitably produce smoke and harmful gases, of which nitrogen oxide emissions have the most obvious impact, these pollutants not only pose a threat to the health of the foundry workers, but also pollute the surrounding environment, therefore, the treatment of foundry smoke has become an important measure of industrial environmental protection.

Casting dust mainly comes from metal melting, pouring and cooling process, and its composition is complex, including metal oxides, silicates, carbon particles and so on. It can cause irritation and damage to people’s respiratory system and increase the risk of occupational diseases. It causes pollution to the environment, affects the regional air quality and affects the sustainable development and corporate image of foundry enterprises.

The SCR denitrification system independently developed by Green Valley Environmental Protection has independent intellectual property rights and a number of invention patents, and has accumulated a lot of experience data in the application field, which can ensure that the project design is reasonable, the operation is stable and reliable, meet the national environmental protection requirements, and the ultra-low emission of nitrogen oxides and ammonia escape are less than 3ppm.

Foundry industry is an indispensable cornerstone of modern manufacturing industry, which has a profound impact on economic development, technological innovation, industrial chain construction, job creation, social infrastructure and national defense security. With the advancement of science and technology, foundries are developing in a more efficient and environmentally friendly direction, contributing to the global industry.
