High gravity ammonia blowing denitrification technology

In response to the problems of large equipment and safety hazards in the liquid ammonia gasification process of SCR denitrification system, "super gravity ammonia water blowing" is adopted instead of "liquid ammonia gasification" to eliminate hazards and achieve intrinsic safety. Applying the enhanced technology of supergravity chemical process to ammonia water blowing and developing supergravity ammonia blowing equipment and technology suitable for denitrification process, blowing free ammonia in ammonia water to the gas phase, and adding it as a nitrogen source to the furnace for denitrification greatly improves the denitrification rate, reduces pollution, and has the characteristics of small equipment volume, low production cost, and high intrinsic safety. This technology is applied to Shanxi Pingshuo Coal Bangshi Power Generation Co., Ltd., with a single equipment processing ammonia water volume of 0.1-0.8m ³/h, dilution air volume of 1000-2400m ³/h, ammonia water stripping rate of over 95%, NOx emission concentration less than 100mg/Nm ³, and ammonia escape concentration less than 8mg/Nm ³.
