摘要
根据硝铵中和反应中pH值控制的特点及工艺条件,确定了pH值与酸/氨比值串级调节方案,并通过可编程序调节器CD600来实现,从而使硝铵中和器pH值的稳定控制取得了满意的效果。
According to the characteristic and process condition of the pH control in ammonium nitrate neutralization reaction, the cascade regulation scheme of the pH and acid/ammonia ratio is formed using the programmable logic controller CD600. The stability control of the pH is achieved in ammonium nitrate neutralizer as well as the satisfactory results.
