[structure and characteristics]

Sieve tray tower is one of the most widely used tower types and has been developed into one of the main mass transfer equipment in chemical production in recent years. Dense holes are drilled on the tray of sieve tray column, which makes the liquid on the tray swell into bubbles for mass transfer when the gas medium passes through the sieve hole.

The graphite sieve plate column has the advantages of simple structure, convenient manufacture, lower cost than the bubble egg tower and float valve tower, and the treatment capacity and plate efficiency are higher than that of the bubble cap tower. However, due to its small production flexibility, not suitable for low gas-liquid load conditions and small screen size, it is easy to block, resulting in little application of graphite sieve plate tower. It can be used in some high temperature and corrosive occasions.
