AI Technical Summary
In the existing technology for the production of calcium ammonium nitrate, the cooling system has a slow response and is difficult to adapt to fluctuations in material flow, resulting in unstable reaction, poor product quality, and failure to effectively recover and utilize reaction heat, leading to serious energy waste. Furthermore, there is a lack of a coordinated mechanism between pH adjustment and material ratio control.
A dynamic diversion control method is adopted to calculate the heat release rate of the neutralization reaction in real time. The calcium nitrate solution is divided into two parts by a proportional diversion regulating valve. One part enters the tubular reactor to absorb heat, and the other part bypasses into the buffer tank. Combined with pressurized flash evaporation dehydration, the heat of reaction is absorbed and utilized in real time. The product quality is ensured by online pH adjustment.
It achieves efficient utilization of reaction heat, simplifies equipment structure, reduces energy consumption, ensures product quality stability and energy efficiency, and avoids the need for a cooling system.
