摘要介绍了HeSNCR智能高效脱硝系统，该系统在分解炉上分层布置喷枪，每层有相应的自动控制阀门，利用人工智能软件实时跟踪窑况变化，通过分析水泥窑系统的各操作参数，准确判断氨水需用量，精确控制每组喷枪，在最合适的喷入点喷进最适量的氨水，实现最高的脱硝效率。该系统还可以在达到最大NOx脱除率的同时，有效控制氨逃逸。从2019年3月至今，系统运行稳定，成功将氮氧化物排放量控制在100mg/m³（标）和50mg/m³（标）。

Abstract: The intelligent and efficient denitration system of HeSNCR is introduced. The system arranges spray nozzles on the calciner in layers where each layer has corresponding automatic control valves, and uses artificial intelligence software to track changes in kiln conditions in time. By analyzing various operating parameters of the cement kiln system, it accurately determines the amount of ammonia required and accurately controls each group of sprays. The spray nozzle sprays the most appropriate amount of ammonia at the most suitable injection point to achieve the highest denitration efficiency. This system can also effectively control ammonia escape while reaching the maximum NOx reduction rate. Since March 2019, the system has been operating stably, and the NOx emissions have been successfully controlled at 100mg/Nm³ and 50mg/Nm³ .

Key words: intelligent denitration high efficiency denitration HeSNCR ultra-low emission
