Nitrogen oxide gas denitrification governance the subsidiary production nitrate About Chengdu PAX Metallurgical Technology Co., Ltd. (Contact: Mr. Pu, telephone 13,880,483,802 QQ: 455 162 924) developed a new type of nitrogen oxide gas off denitrification governance of subsidiary production of nitric acid plant has obtained national patent (Patent No.: 201220021181.2), has the following characteristics: 1, the new nitrogen oxide gas denitrification governance device is particularly suitable for the high concentration of nitrogen oxide gas denitrification governance, the concentration of nitrogen oxide gases from hundreds to hundreds of thousands of mg / Nm3. The processing gas in a broad temperature range, usually less than 350 ℃ may. 2, this new type of nitrogen oxide gas denitrification governance devices governance thoroughly governance to achieve the emission requirements of GB (100 200mg/Nm3). 3, the new nitrogen oxide gas the device processing gas denitrification governance unrestricted, regardless of the gas size can be implemented. Subsidiary production of low concentration of nitric acid (50%) of 4, the new nitrogen oxide gas denitrification governance device in nitrogen oxide gas denitrification governance, environmental governance at the same time 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, high degree of automation system, running extremely stable and reliable, saving labor. 7, the company has a hour nitrogen oxide gas handling capacity of 1000m3 / h along with production of nitric acid device available for customer inspection visit. 8, this nitrogen oxide gas customers off denitrification governance of subsidiary production of nitric acid plant can lay a solid foundation for the support of the State Environmental Protection Fund. The nitrogen oxide gas denitrification governance of subsidiary production of nitric acid plant is widely used in the following industries: 1, all kinds of nitrate production industry; 2, molybdenum, nickel ore, nickel-copper, gold, silver, tungsten, molybdenum, vanadium and other precious metal nitrate leaching process; 3, the the solar polysilicon industry nitrate cleaning process; 4, stainless steel nitric acid wash industry; 5, the nitrogen fertilizer industry; 6 the glass cement thermal power industry. The advantage of the nitrogen oxide gas off the denitrification governance of subsidiary production of nitric acid plant equipment, small size, low power consumption, all stainless steel, safe and reliable operation, mission long. Welcome to the industry outside colleagues call us and come to visit the tour guide. Appendix: the nature of the oxides of nitrogen gas, and its control technology, the nature of the oxides of nitrogen gas at room temperature and atmospheric pressure nitric oxide is a colorless, odorless and highly toxic gas. Immediately oxidized in air rapidly into a mixture of NO2 and N2O4. Nitric oxide toxicity was mainly caused by the strong transformation of nitrogen dioxide toxicity. NO in air is oxidized to NO2, turn hydrolyzed to nitric acid and nitrous acid, at room temperature and high temperature, humid NO corrosion of most metals. Nitrogen dioxide odor asphyxiating stimulus corrosive the tawny toxic gas. The real standard ambient temperature and pressure, it is a balanced mixture of NO2 and N2O4, with temperature and pressure them into each other. Nitrate and nitrite, reacts with water to produce intense irritation and corrosion, caused by the human acute poisoning and chronic poisoning. Nitrogen oxide gas is actually a greenhouse gas, and sulfur dioxide gas, causing extremely serious harm to the environment. It can also be mixed with water vapor in the atmosphere, causing acid rain to corrode metal and cause great harm to crops such as. Governance objectives of the National 12th Five-Year Plan on atmospheric pollutants include its governance, and included in the list of major pollution sources, focus on the implementation since 2012. Therefore, the environmental protection departments at all levels will focus on monitoring. Second, the technical characteristics, emissions requirements and standards, emissions targets: nitrogen oxides (as NO2) ≤ 200mg/Nm3 minimum ≤ 100mg/Nm3. 2, the company has a national patent technology, nitrogen oxides denitrification treatment has the technical and cost advantages unmatched by other craft. Patent No.: 201,220,021,181.2. 3, dilute nitric acid; subsidiary production of about 30% can return to production systems, reduce costs, turning waste into treasure, zero discharge of wastewater. The typical nitrogen oxides governance recycling demonstration effect. 4, easy to operate, fully automatic operation, phenomenon never occurred crystalline substance clogging pipes and burned equipment.
