Tray efficiency improving device

The invention provides a tray efficiency improving device, which comprises a guide cylinder embedded in a through hole of a tray, the top edge of the guide cylinder extends in the direction deviating from the center of the guide cylinder to form a limiting flange, and the diameter of the limiting flange is larger than that of the through hole; and the at least two turbulent flow blades are fixed in the guide cylinder and are obliquely arranged at a preset angle with the vertical direction. The tray efficiency-improving device is arranged at the through hole of the tray, air flow is divided into a plurality of small air flows by the turbulent flow blades when passing through the tray efficiency-improving device, and the small air flows enter a liquid holding layer above the tray in an obliquely upward manner, so that the gas-liquid contact area can be increased, and the gas-liquid mass transfer efficiency is improved; therefore, when the tray is under various working conditions, smoke can generate a violent bu
