Tower internals

The inner parts of the tower provide a contact place for mass and heat transfer for gas-liquid phase and liquid-liquid phase; There are two main types of tower internals: packed towers and plate towers. The packing tower internals mainly include packing, liquid distributor, liquid collector redistributor, gas distributor, packing fastening device, packing support device; The internal parts of the plate tower mainly include: tray, liquid collection tank (plate tower), plate support device (plate tower), feed distributor, gas feeding and distribution device and defoamer, etc.

A complete packed tower is composed of tower internals and packing and tower body. The role of the tower internals is to make better contact between gas and liquid in the tower, so as to give full play to the production capacity and efficiency of the packing tower, so the design of the tower internals directly affects the operation and operation of the entire packing tower and the performance of the packing. In addition, the "amplification effect" of the packing tower In addition to the inherent factors of the packing itself, the tower internals also have a great influence on it.

The tower internals mainly include the following parts:

1. Liquid distribution device

Second, packing pressing device

Third, packing support device

4. Liquid collection and redistribution and feeding and discharging device

5. Gas feeding and distribution device

6. Defoaming device
