新型垂直筛板塔是一种喷射型板式塔。自90年代起新型垂直筛板塔受到了小氮肥行业的重视,并被逐步采用,取得了良好的效果。现根据小氮肥厂使用结果整理如下: 1 碳化工段回收清洗塔上的应用 在碳化工段中回收清洗塔的作用是在满足工艺用水平衡的条件下,回收碳化尾气中的NH_3和吸收尾气中残存的CO_2,控制尾气中的NH_3和CO_2分别在0.1g/m~3和0.2％ The new vertical sieve tray is a spray-type tray tower. Since the 90’s the new vertical sieve tower has received the attention of the small nitrogen fertilizer industry and has been gradually adopted with good results. The results are based on the use of small nitrogen plant finishing as follows: 1 carbonation section of the recycling tower cleaning application Carbonation section of the recycling tower cleaning role is to meet the balance of process water, carbonized exhaust gas recovery and residual NH_3 CO_2, the control of exhaust gas NH_3 and CO_2 at 0.1g / m ~ 3 and 0.2%
