| Abstract: |
| In this paper, the sieve tray with shunt type downcomer was studied and then the cold model experiment was conducted in air-water system. Hydrodynamic performance of the sieve tray with shunt type downcomer was systematically studied. Under the same operating conditions, compared by the sieve trays with no shunt type downcomer, the total pressure drop of tray is reduced on average by 14.3%, the clear liquid height of tray is reduced on average by 12.1%, the operating flexibility of tray is increased on average by 15.3%, and then the high limit of liquid flooding and the processing capacity of tray was improved effectively. |
