Tower internals is the important component of packing tower, it constitutes a complete packing tower with packing and tower, the function of all tower internals is for better contact of gas and liquid phases in the tower, so as to fully play the ultimate efficiency and the largest productivity of the packing, Packing tower internals including liquid distributor, liquid redistributor, gas distributor, packed bed limiter, defoaming device etc.

Gas distributor :
Gas distributor has various types, it is decided by gas phase state, application, vapor load, operating pressure, allowable pressure drop, tower diameter and other factors. The design of gas distributor is especially important under the circumstances of large tower diameter, high load and low bed.
