The power line tower is a type of plate tower with a downcomer. The bubble zone is composed of parallel angle steels, and the arrangement direction of the angle steels is

The direction of liquid flow is parallel. The sharp edge of the angle steel is located at the lower part, with a "V" shaped cross section. There is a certain gap between adjacent angle steels, which lowers

The liquid pipe is the same as a regular tray. The liquid from the previous plate flows into the "V" - shaped angle steel through the downcomer, while the gas rises through the grid gap

Bubbling occurs with the liquid during mass transfer, and the gas-liquid flow state on the tray is similar to that on the sieve plate. The pressure drop of the angle steel tower plate is relatively small,

The gas flow rate is large, the tray efficiency is good, the structure is simple, the processing and manufacturing are convenient, and the stiffness is good. But the efficiency is not high when the processing capacity is small

Like a sieve tray tower.
