Power transmission tower is a plate tower with a downcomer. The bubble section is composed of angle irons arranged in parallel.

Parallel to the direction of the liquid flow. The pointed edge of the angle iron is at the bottom, the cross-section is in the shape of a "V," and there is a certain gap between adjacent angle irons. The downcomer pipe is generally...

The trays are the same. The liquid from the previous tray flows into the "V" shaped angle iron through the downcomer, while the gas rises through the slats, causing bubbling with the liquid and facilitating transfer.

The quality process, the gas-liquid flow state on the tray is similar to that on the sieve plate. The angle steel tray has a lower pressure drop, a higher gas throughput, and better tray efficiency, with a simple structure.

Easy to process and has good rigidity, but is less efficient than a sieve plate tower when handling small quantities.
