What are the types of liquid distributors?

Grooved liquid distributor, tray-type, tube array type, ring tube type, nozzle type

The liquid distribution devices for packed towers that I am aware of include: tubular sprayers, porous tubular sprayers, pellet-type sprayers, and disc distributors

Additional information for the 2nd floor: there are also tubular distributors, fully interconnected liquid distributors, and tray-type distributors

Grooved liquid distributor: Suitable for larger towers, requiring more vertical space inside the tower, but offering better performance. Tray-type: It is relatively compact; it occupies more vertical space inside the tower, but it offers good performance. It is currently the most commonly used in medium-sized towers. Tubular and loop-type: simple distributors that require little vertical space; they can be considered if the distribution requirements are not high. Nozzle type: It is hardly used these days; its performance is the worst. A certain pressure is required to ensure spraying over a large area. Additionally, flow-blocking rings are also used, which can also serve a distribution function.

They are divided into gravity-type and pressure-type distributors. Gravity-type distributors are used in cases of large tower diameters and high flow rates. The main types include trough-type liquid distributors, which can be either single-main-trough or multi-main-trough types; in addition, the main trough and the secondary troughs may be located at different heights； There may be a secondary distributor ； Slot tray type: mainly used in collection and redistribution or extraction applications, and is equipped with a rising gas cap ； Good control over levelness is required ； Tubular: Relatively simple, mainly used in multi-stream trays ； A pressure-type distributor of the tubular type; it does not require nozzles, and usually features a row of holes arranged at a 45-degree angle downward ； Nozzle type: Generally used with bulk packing materials; the choice of model depends on the spraying angle and the requirements regarding overlap. Nozzles of this type are relatively expensive; of course, these nozzles are not the same as shower heads.

What was said upstairs are all the usual options; currently, Tianjin University has the most varieties. There are dozens of types of liquid collectors, and I’ll upload some photos from the site when I have time

That’s great; Tianjin University is a very renowned manufacturer of tower internals. We in the industry often come across their products when bidding on projects.
