Due to the subdivision of the distribution box 50 in the said chambers 56 . 58 Can the over the inlet 54 in the upper chamber 56 inflowing liquid F before being introduced into the inlet pipes 40 be evenly distributed in the box longitudinal direction. The intermediate floor 57 is therefore also called a pre-distributor.

Furthermore, it can be provided that the distribution box 50 at least one overflow chimney 70 which has the intermediate floor 57 go, wherein the at least one overflow chimney 70 the upper chamber 56 with the lower chamber 58 connects, allowing the liquid phase F from a certain level in the upper chamber 56 over the at least one overflow chimney 70 from the upper chamber 56 into the lower chamber 58 can get.

The liquid distributor described above 1 is operated in the following way. About the inlet 54 the liquid phase F runs into the upper chamber 56 of the distribution box and accumulates there. About the openings 59 and the openings 47 the liquid phase F runs into the feed pipes 40 , From the supply pipes 40 the liquid phase F passes over the openings 22 . 23 in the transverse distribution pipes 20 , From the transverse distribution pipes 20 can the liquid phase F through the openings 21 into the distribution pipes 10 reach. About the openings 12 the distribution pipes 10 Finally, the liquid phase F is removed from the liquid distributor 1 issued and, for example, reaches an underlying packing bed.

By appropriate dimensioning of the individual outlet openings 12 For example, the volume flow of the liquid phase F can be regulated so that it emerges uniformly over the entire distributor bottom side.

For the preparation of the liquid distributor 1 can, for example, first the feed pipes 40 , the transverse distribution pipes 20 and the distribution pipes 10 with all necessary openings 12 . 15 . 16 . 21 . 22 . 23 . 44 . 45 . 47 Mistake. The ends of said pipes 10 . 20 . 40 be sealed in particular.

Then the transverse distribution pipes 20 in the middle inlet pipe 40 be plugged in.

After that, the respective anti-rotation tube 60 in the respective opening 23 of the transverse distribution pipe 20 plugged in and with the corresponding inlet pipe 40 be riveted.

Then can both sides of the inlet pipe 40 clamping rings 17 . 18 on the transverse distribution pipes 20 be plugged.

After that, a distribution pipe is made on each side 10 on the transverse distribution pipes 20 pushed on and other clamping rings 17 . 18 ,

The clamping rings 17 . 18 then be with the distribution pipes 10 and the transverse distribution pipes 20 jammed.

After this, at least one, preferably two, spacers are formed on each side 30 on an associated transverse distribution pipe 20 attached and fixed there.

Thereafter, in a similar manner again clamping rings 17 . 18 and distribution pipes 10 as well as spacers 30 on the corresponding transverse distribution pipes 20 be deferred to those in the 1 To produce shown tube assembly.

After completion of the pipe assembly from inlet pipes 40 , Transverse distribution pipes 20 and distribution pipes 10 and in particular spacers 30 becomes the distribution box 50 or the soil 51 on the inlet pipes 40 put on and welded with these. After that, the distribution box 50 ready to be welded.
