Denitrification attached producing nitric acid plant in Chengdu PAX Metallurgy Technology Co., Ltd. developed a new nitrogen oxide gas treatment technology subsidiary production of nitric acid plant (denitrification) has obtained national patent (Patent No.: 201220021181.2), has the following characteristics: 1, especially for high concentrations of nitrogen oxide gas treatment, from hundreds to hundreds of thousands of mg / Nm3. The process gas temperature is not limited. 2, thorough governance, governance can achieve the emission requirements of GB (100 to 200mg/Nm3) time. 3, the process gas unrestricted regardless of gas size can be implemented. 4, subsidiary production of low concentration of nitric acid (50%), while in the environmental management bring considerable economic benefits. 5, the processing cost is very low, a wide range of sources of raw materials and cheap (only with air, water, electricity). 6, state-of-the-art technology: the oxidation of organic combination of absorption and special treatment. The system has a high degree of automation, extremely reliable operation, saving labor. 7, the company has a hour nitrogen oxide gas handling capacity of 1000m3 accompanied by producing nitric acid unit available for customer inspection visit. Customers this denitration subsidiary production of nitric acid plant and lay a solid foundation for the support of the State Environmental Protection Fund. The denitrification of subsidiary production of nitric acid plant is widely used in the following industries: a nitrate production industry; precious metals, molybdenum, nickel ore, nickel, copper ore, gold, silver, tungsten, vanadium nitrate leaching process. 3, the solar polysilicon industry nitrate cleaning process. 4, stainless steel nitric acid wash industry. 5, the nitrogen fertilizer industry. 6, the glass the cement thermal power industry. For the denitrification of producing nitric acid plant equipment, small size, low power consumption, all stainless steel, safe and reliable operation, the use of the mission of the advantages of long.
