Abstract:

To reduce steam consumption during ammonia stripping from coal water,large hole flow\|guided sieve tray is adopted in the design of ammonia stripper.Chemical engineering simulation software is used to simulate and optimize the relationship between number of trays and steam consumption.Compared with bubble cap ammonia stripper,steam consumption per ton coal water is reduced by 30kg,ammonia content in waste water is reduced to 30mg/L from 50~100mg/L,and it is more convenient to inspect and repair the ammonia stripper.
