Abstract
The tower made of oval ripple sieve tray：It is made of tower top, tower body and bottom of tower.Master unit be semiellipse ripple sieve tray be by be equipped with porous semiellipse pipe be welded on be equipped on each pipe on disk 40% or more hole, the baffle of tower tray lower end is that its lower half portion of downspout is to be equipped at porous camber line to slightly higher of lower piece of column plate discharge weir top to meet at tower body into enclosed shape, and liquid is spilt by sieve pore；Tower body is entirely novel invention；It does not set and holds liquid zone.
Description
Technical field：Chemical industry；Environmental protection；Gas is absorbed, washing, is sprayed, VOCs is administered
Background technology：The gas that absorption tower is widely used in petrochemical industry field of environment protection is absorbed, washing, is sprayed, VOCS processing
In, absorption tower is divided into board-like and two big type of packed tower：Packed tower is chiefly used in handling small gas flow, large-minded required when handling
When the tower diameter wanted is big, column efficiency degradation can be made because gas-liquid is unevenly distributed；In addition packed tower also has that pressure drop is big, gas
The defects of liquid entrainment is serious.In big tower diameter, plate column is inevitable choice, and the area that the efficiency of tower is contacted with liquid-gas is related,
The more traditional tower of the present invention, improves 20% or more contact area, and the mode for using liquid-gas non-perpendicular contact is come
Reduce the generation of idle work entrainment.This patent has selected efficient oval corrugated sieve column plate, this column plate is because being equipped with overflow
Weir so that the liquid holdup of plate layer is stablized, and to which the pressure drop of whole tower becomes definite value, pressure tower drop is more small than with high packed tower,
The empty tower gas velocity of permission is more high than the packed tower of same diameter.Yin Tanei《Semiellipse corrugated sieve column plate》The present inventor is
The patent of application is (to not only increase mass-transfer efficiency for non-vertical direction with column plate plane and also effectively reduce in most sieve pores
Entrained liquid).Tower is simple to manufacture, and cost and manufacture difficulty are little.Because every layer of column plate is exactly a liquid distribution trough, therefore not
Separately set liquid distribution trough.Therefore the tower no liquid distributor therefore liquid of structure are gone directly bottom of tower by tower top, and reducing has liquid point
Many places inlet tube-partially liq flow of cloth device is short, therefore the washing effect in same amount of liquid significantly improves, in downspout
It uses《A kind of downspout with aft cover plate》The patent that the present inventor is applying.This patent is the present inventor's tower series
One of new idea.
The invention content present invention 1,1, be use《Semiellipse sieve pore ripple tray》It is by more that (separately applying), which is master unit-,
A semiellipse tube wave peak for having beaten hole is welded into plate face upwards, is equipped with 40% or more hole, an arc string has been lacked on tower tray about
It is that perpendicular to the baffle of tower tray, baffle top is put down higher than tower tray for welding one on tower tray string that 10% tray area, which is downflow weir-,
Baffles of the face 40-70mm (being known as liquid holdup) in tower tray lower end is downspout；2, it is the patent for using me and applying
《Ligulate sieve pore downspout》, under which is straight, start to be equipped on plate washer at about 1/2 tower layer height porous
And ligulate is curved into tower wall in lower layer's downflow weir
Manufacture material：Steel；Stainless steel, plastics, plastimets etc..The scope of application；Tower diameter 0.6-5.5m is (excellent
Select 2-4.5m), normal pressure, room temperature.
Specific implementation mode：The tower made of oval Wave screen plate is novel absorbent tower：It is big by tower top, tower body, bottom of tower three
Part forms.Tower top is that gas vent is connect with pipe flange (see Fig. 1)；Here is demister；It is that inlet tube is led to still further below
It is directly punched in tower and in the lower half portion of pipe；Tower body is often to save multilayer column plate staggered, master unit tower by multiple tower sections
Plate is that semiellipse ripple sieve tray (separate case)-is welded on steel pipe on the disk of garden by the semiellipse pipe of the long diameter 89-159mm punched
It is equipped with the hole of 40-60%；It is in tower tray string that the area that about 10% tower tray of an arc string vacancy has been lacked on tower tray, which is downflow weir-,
Perpendicular to the baffle of tower tray, baffle top is in tower tray lower end higher than tower tray plane 40-70mm (being known as liquid holdup) for upper welding one
《Ligulate sieve pore downspout》(separate case) starts to beat on plate washer under the downspout elder generation plate washer is straight at about 1/2 tower layer height
Have porous and curve into ligulate and tower wall and join into closed pipe at 1.1-1.3 times of lower layer's height of weir plate, liquid is only
Have and is spilt by the hole on ligulate face；Liquid-bearing pan is not set on tower tray；The bottom of tower top (see Fig. 1) is connected by flange with tower body, even
It is the tower inner wall that air inlet pipe enters that the another side of import is arrived on top in tower under acting flange, and opened in the middle and lower part for entering pipe in tower
There is area to be more than the hole of air inlet pipe sectional area, the pore size distribution center centers Ying Yuta are identical.It is outlet tube still further below, at tower most bottom
Portion is equipped with sewage draining exit.
Description of the drawings：Fig. 1 is the sectional view of the tower made of oval ripple sieve tray, and wherein tower body is more piece multilayer, there is two
A critical piece is completely new：Column plate is《Semiellipse sieve pore ripple tray》；Downspout is《Ligulate sieve pore downspout》；Column plate
Upper nothing holds liquid zone；Tower top and bottom of tower are to be formulated conventionally；Fig. 2 is downspout lower part aft cover plate sieve pore region shape schematic diagram --
It is《Ligulate sieve pore downspout》It is to be provided with porous ligulate screening liquid plate to enclose pipe in downspout lower part；Fig. 3 is column plate trepanning
Schematic diagram-《Semiellipse sieve pore ripple tray》Garden is welded on by the semiellipse pipe peak of the long diameter 89-159mm punched upwards
Steel pipe is equipped with the hole of 40-60% on disk；The area that about 10% tower tray of an arc string vacancy has been lacked on tower tray is downflow weir.
