As for liquid distributors selected for special application, uniform liquid inlet amount is crucial for achieving optimum performance. Inlet system must make liquid evenly distribute in the whole liquid distributor as much as possible, and drainage speed and liquid pressure fluctuation should be considered at the same time.
Liquid inlet amount is special important for high liquid load and large-diameter packed towers.
The basic design scheme is as below:
Ladder-type inlet devices, lower and medium liquid load (<80m3/m2h, measuring range ratio of 1:3) and Parting boxes with down spouts, higher liquid load and wider declining range (1:10 or higher)
Specially designed parting boxes can be used in processing mixture of two phases in high temperature.
Such a liquid inlet distribution system before the distributor does not need lower liquid load (5m3/m2h at least) and packed tower with smaller diameter.
Designs of the above-mentioned liquid inlet systems have own specific advantages.
But not every design applies to all different types of liquid distributors.
Our knowledge and experiences can select optimally configured liquid inlet device and distributor for your special application.
