Study on the Hydrodynamic Performance of a Countercurrent Total Spray Tray under Sloshing Conditions

In this paper, a new type of total spray tray (TST) with gas–liquid countercurrent contact is proposed to solve the problem slight operation flexibility and poor sloshing resistance in towers under offshore conditions. Its hydrodynamic performance indicators, such as pressure drop, weeping, entrainment, liquid level unevenness, were experimentally studied rolling motion. A tower an inner diameter 400 mm spacing 350 was installed on platform simulate The experimental results show that motion affected When amplitude did not exceed 4°, degree fluctuation small, could still work stably. With increasing amplitude, TST wet plate unevenness fluctuations also increased. reached 7°, maximum drop 8.9% compared static state, hole kinetic energy factor, lower limit increased rapidly from 6.2 at rest 7.8 It can be seen exhibits good
