At the weekend, it was reported from the Fengshan Chemical Branch of Hebei Suizhong Energy Well Mines Group Co., Ltd. that the independent research and development of the nitrate salt evaporation crystallization process emission reduction technology has been applied continuously for two years, and the steam consumption of the ton salt product has dropped by 75%. It has created a new record for domestic energy-saving and emission reduction of nitrate salt production. This technology has also won the China Enterprise New Record Award.
Nitrate production new technology integrates the use of double-effect negative pressure evaporation, crystallization, waste heat recovery heating, a closed condensate water recycling and other recycling technology, to achieve steam classification recycling. Among them, the double-effect negative pressure evaporation process is to recycle the secondary steam and condensate water produced by one-effect evaporation, and then install a heat exchanger at the outlet of the secondary effect evaporation gas. The generated steam can be more than 80,000 square meters around the enterprise. Meter residential and office building heating. The crystallization technology is to change the atmospheric pressure crystals into the domestic advanced vacuum flash negative pressure crystals. The method of continuously replenishing the solid sodium carbonate by the neutralization liquid will increase the solid concentration of the raw material liquid from the original 350 g/liter to 500 g/liter. The system material flow dropped by 33%.
Sodium nitrate and sodium nitrite are collectively known as nitrates and are widely used in medicine, dyes, chemical fibers, glass and other industries. The nitrate salt industry in China has developed rapidly in recent years and has been transformed from a nitrate salt importing country to an exporting country. At present, China's nitrate production methods mainly include the direct method and the exhaust gas method. However, no matter which kind of technology has the defects of high energy consumption, low output of nitrate, and difficulty in meeting the discharge of exhaust gas, the nitrate industry needs to explore energy conservation and consumption reduction. Clean production of new technologies.
Since 2002, Fengshan Chemical Subsidiary Co., Ltd. has started to carry out technological innovation and transformation of the key systems for energy consumption in production, with a total investment of 26 million yuan, and completed the development of technology such as salt evaporation and crystallization. At the end of 2007, the new process was put into operation. After more than two years of application monitoring, the company realized a significant reduction in energy consumption and material consumption. The coal consumption per ton of product decreased from 0.284 tons to 0.07 tons, which was a drop of 70% compared with the past. The use of this technology can achieve 73,300 tons of standard coal, 390,000 tons of water, and 117.87 million tons of nitric oxide and nitrogen dioxide per year, with an annual increase of 35 million yuan. The steam consumption of the nitrate salt per ton product is lower than that of the average domestic nitrate production scale enterprise by 55 percentage points, ranking first.
