Experiences in the Steel Industry

Since the steel industry has implemented ultra-low emissions, China's steel industry has made obvious progress in environmental protection and dust removal. However, due to the large steel production in China, the emission of sulfur dioxide, nitrogen oxide and particulate matter in the steel industry is ranked third, third and first respectively. Therefore, it is still a long way to go for desulfurization and denitrification and dust removal in steel industry.
The filter material needed for steel dust removal is treated by proper surface according to the characteristics of exhaust gas emission dust, and it has the characteristics of high efficiency filtration of various dust. In many cases, the dust viscosity is very high. In this case, we will treat the filter material with water repellent and oil-resistant chemical impregnation, which can improve the cleaning degree of filter material and make it possible to clean the filter material by low pressure reverse blowing. At the same time, according to different technological requirements, PTFE emulsion impregnation can also be used to filter the material, so that the product can show its superiority in the case of high combustibility of the dust.

Years of industry experience and successful cases have proved that Wuxi Guoju's outstanding contribution in this industry has reflected its advantages in service life, ultra-low emission and higher cost performance.
