Definitions
- the invention relates to a device for distributing liquid in mass transfer columns, in which gas or steam flows from bottom to top and liquid from top to bottom, which are equipped with disordered or structured packings, the degassed liquid via liquid collectors being too expensive - And inlet channels can be fed
- the mass transfer columns are predominantly used in separation technology, such as rectification, distillation, absorption, desorption, gas scrubbing, reactors, etc. for the separation of certain mixtures of substances.
- separation technology such as rectification, distillation, absorption, desorption, gas scrubbing, reactors, etc.
- the streaming media namely gas or steam
- So-called exchange trays are used for this purpose, but also disordered full bodies and ordered packings.
- the most uniform possible distribution of liquid over the entire cross-section is of the utmost importance for the good effect of the exchange elements used, such as full bodies or packs.
- channel flows or poor wetting occur within the filler body layers, which in turn increases the effectiveness of the exchange elements used or the funct ion of the exchange columns is considerably restricted or reduced
- the liquid flowing from a packing bed is collected in a liquid collection and - in the case of an additional liquid supply - with the incoming liquid
- Liquid flow mixed Via a pipe and / or shaft construction, the liquid is led from the liquid collector into the main channel and / or secondary channels of the distributor. This transfer of the liquid takes place in one or more stages in a closed or open version, but always in the form that the liquid flows according to gravity.
- liquid gradient which arises on the flow path in the channels leads to different accumulation heights above the outflow openings and thus, above all, to a non-uniform flow with low liquid loads
- the invention has for its object to provide a device of the type mentioned in such a way that a uniform liquid distribution over the entire column cross section in a wide load range regardless of
- inlet troughs are attached under the pre-distributor troughs and distribution chambers are placed on the inlet troughs, which are connected to the inlet troughs via hydraulically defined openings and the liquid according to the principle of communicating tubes into the distributor chambers from below rises above and can be distributed to the packs via outlet openings and distribution devices.
- Ring channel or liquid collector attached at any cross-sectional point of the column. It is also advantageous that the outlet openings are provided with downward-pointing, jet-deflecting profiles attached to the outside of the distributor chambers and connect to the outlet tips
- the device shown in the drawing in a diagrammatic view has an annular channel 1 to which any number of pre-distributor channels 2 are connected. Below such a pre-distributor channel 2, namely arranged transversely to it, there are inlet channels 3 which are connected via an inlet opening 9 in the bottom of the channel 2. There are hydraulically defined openings 5 in a horizontal intermediate wall 10 of these inlet channels 3, with 10 distribution chambers 4 connecting above this intermediate wall.
- the distribution chambers 4 are with
- outlet openings 7 through which the liquid can flow downwards via jet-deflecting profiles 6, which are placed on the outside of the distributor chamber 4 as U-shaped channels.
- drain tips 8 follow in the area of the beam-deflecting profiles 6 and feed the liquid to the fillings or packings
- the described supply of the liquid via an annular channel 1 into the pre-distribution channels is also possible via a collector arranged in the center of the column and / or further liquid supply points.
- the free spaces between pre-distribution channels 2 and inlet channels 3 allow the gas to flow unhindered from below stream above
