Abstract

The utility model discloses a duplex liquid distributor suitable for the initial distribution of regular filler tower liquid, which is composed of a multiple ring tube type distributor and a metal ring rectangular saddle filler layer on a tower section. The filling height h2 of the metal ring rectangular saddle filler layer is 120 to 360 mm, and the nominal size of used rings is Dg15 to 25 mm. The interval height h1 between the multiple ring tube type distributor and the metal ring rectangular saddle filler layer is 0.5 to 0.6 times the difference value of the ring radiuses of adjacent ring tubes. The utility model has the advantages that the utility model has a plurality of spraying points which are distributed equally, the rate of void passed by air is high, free section is large, resistance is small, and the difficulties of design, manufacture and installation are small.

Description

Compound liquid distribution trough

The utility model proposes a kind of compound liquid distribution trough that is applicable to that regular packed tower liquid just distributes.

Packed tower is a gas-liquid mass transfer (contact) equipment commonly used of realizing unit operations such as distillation, absorption in the Chemical Engineering.Be divided into random packing tower and regular packed tower by its filler type.Practice data shows in recent years, and liquid is vertically dirty in structured packing, does not have the bias current phenomenon, so its enlarge-effect is very little, but the spray that liquid just distributes is counted and the uniformity requires highly, must guarantee every 30cm ²Tower section has a spray point to be advisable.So require to make liquid distribution trough, especially tower used liquid distribution trough in the big footpath of industrialization is guaranteeing that its design, manufacture difficulty are very big under the enough free breathing area prerequisite.By contrast, the random packing of better performances is because of having the ability of preferable automatic uniform liquid, and first distribution did not then have severe requirement to liquid.

The existing distribution performance that is applicable to regular packed tower is liquid distribution trough preferably, and its structure type mainly contains fin and tube type, annular tube type, Alveolus type etc.Its sprinkle density is many at every 100cm ²Left and right sides tower section just has a spray point, and because of ventilation cross section and Machine Design restriction, the spray point distributes to go up has the density band to exist more.

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of compound liquid distribution trough.

Technical solution of the present utility model:

Combine in tower joint 3 by many endless tubes pattern distributor 1 and becket intalox saddle layer 2; The loading height h of becket intalox saddle layer 2 ₂Be 120～360mm, the nominal dimension of used ring is Dg15～25mm; Between many endless tubes pattern distributor 1 and the becket intalox saddle layer 2 at a distance of the height h ₁Be 0.5～0.6 times of the difference in adjacent ring pipe ring footpath.

Advantage of the present utility model:

(1) spray is counted many and is evenly distributed, make structured packing particularly every meter efficient of vertical moire type structured packing (or every meter plate number) be improved.

(2) voidage height, the free cross-section passed through of gas is big, and then resistance is less.

(3) design, manufacturing and installation difficulty are less.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2,3,4 is respectively that A-A, B-B, C-C cut open and show structural representation.

Further describe technical solution of the present utility model below in conjunction with accompanying drawing:

This distributor is made up of parts such as many endless tubes pattern distributor 1, becket intalox saddle layer 2, tower joint 3 and grate plates 4, and its architectural feature is:

1. carry out (slightly) distribution just with 1 pair of liquid of many endless tubes pattern distributor, be convenient to guarantee hoop, radially simultaneously uniform.At 300～2400 (mm) industrial tower, main design size is as follows: the difference DELTA D=D in adjacent ring pipe ring footpath for diameter D _I+1-D _iGet 2 * (75～180) millimeters, its value height is decided (for a certain distributor, Δ D is a definite value) according to the tower diameter size; Interior ring diameter D ₁Get 120～Δ D millimeter; Tower diameter D gets (0.60～0.80) Δ D with the difference of outer ring diameter; Opening diameter φ 3～6mm, 25～40 ° of perforate angle theta, the perforate sum is to guarantee per 30～140cm ²Tower section has spray point and decides; Caliber designs according to hydrodynamics, and must not be lower than the arm perforate gross area.

2. do to distribute again with 2 pairs of liquid of becket intalox saddle layer of automatic uniform better performances, make the further refinement of spray point, the amplification of counting, and the uniformity further improves.The main design size corresponding with parts 1 is as follows: the nominal dimension of ring intalox is D _g15～25 millimeters; The loading height h of packing layer 2 ₂It is 120～360 millimeters; Between packing layer 2 and the distributor 1 at a distance of the height h ₁Be (0.5～0.6) Δ D millimeter.

By the distributor of above-mentioned characteristic Design, test shows: spray is counted many, can reach every 20cm ²Left and right sides tower section has a spray point, and hoop integrated radial good evenness.

This compound liquid distribution trough adopts flange to connect with the assembling of regular packed tower joint, so be convenient to on-the-spot the installation.

Claims

1, compound liquid distribution trough is characterized in that being combined in tower joint (3) by many endless tubes pattern distributor (1) and becket intalox saddle layer (2); The loading height h of becket intalox saddle layer (2) ₂Be 120～360mm, the nominal dimension of used ring is Dg15～25mm; Between many endless tubes pattern distributor (1) and the becket intalox saddle layer (2) at a distance of the height h ₁Be 0.5～0.6 times of the difference in adjacent ring pipe ring footpath.
