Oval ripple sieve-plate tower.Technical field：Chemical industry；Environmental protection；Gas is absorbed, washing, is sprayed, VOCs is administered.Oval ripple sieve-plate tower is the New-type plate absorption tower advantageous in high throughput, is made of tower top, tower body and bottom of tower.Master unit is that semiellipse corrugated sieve column plate is by beating porous semiellipse tube welding on the disk of garden, and peak is all that upward being welded in a plane constitutes waveform sieve tray between each semicanal；It is that the retroflect the tip of the tongue of shape goes out at liquid with column plate upwards in parallel that downspout lower part, which sets screening (folding) flowing plate, and boom plate is provided with multiple half circular holes below makes liquid in the outflow of ridge shape；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
Tower diameter it is big when, because gas-liquid is unevenly distributed can make column efficiency degradation；In addition packed tower also has that pressure drop is big, gas-liquid folder
With it is serious the defects of.In big tower diameter, plate column is inevitable choice, and the area that the efficiency of tower is contacted with liquid-gas is related, at present
Alternative plate column is few in industry, and column efficiency is not high.This patent is exactly to use two the present inventor just to declare
Patent《Semiellipse sieve pore ripple tray》With《A kind of downspout with aft cover plate》Mist folder is reduced to improve gas liquid interfacial area
One idle work of band, to improve tower working efficiency.Two patented technologies are taken in column plate and downspout, theoretically, every
Effectively 20% or more (increase of plate plane) of contact area increase has manufactured non-perpendicular contact to a certain extent on layer column plate
Mode can also increase column efficiency and play the role of eliminating mist.Cause《Semiellipse corrugated sieve column plate》(the present inventor is applying
Patent) most sieve pores in tower be with column plate plane are that non-vertical direction (not only increases mass-transfer efficiency and also effectively reduces
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, thus it is not another
If 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 distribution
A part of liquid flow of many places inlet tube of device is short, therefore the washing effect in same amount of liquid significantly improves, and makes in downspout
With《A kind of downspout with aft cover plate》Also the patent that the present inventor is applying.This patent is that the present invention enters tower series
One of new idea.
Invention content ellipse ripple sieve-plate tower is completely new tray absorption columns, it is by tower top, tower body and bottom of tower three parts
Composition, wherein influencing maximum to be the exactly completely new invention place of this army of tower body point on column efficiency.Present disclosure：This hair
Bright 1, it is to use《Semiellipse sieve pore ripple tray》(separately apply) be master unit-be from multiple semiellipse tube wave peaks for having beaten hole to
On be welded into plate face, be equipped with 40% or more hole, about 10% tray area of arc string lacked on tower tray, be downflow weir-be
Welding one is perpendicular to the baffle of tower tray on tower tray string, and baffle top is higher than tower tray plane 40-70mm (being known as liquid holdup) in tower tray
The baffle of lower end is downspout；2, it is the patent for using me and applying《A kind of downspout with aft cover plate》(separate case Shen
Please)-and it is that downspout lower part sets aft cover plate, aft cover plate is that the retroflect the tip of the tongue of shape goes out at liquid with column plate upwards in parallel；In downspout
Boom plate is provided with multiple straight half circular holes below makes liquid be flowed out in ridge shape；3, it does not set and holds the gas-liquid contact that liquid zone not only increases 10%
Area also makes the air-flow for holding liquid zone rising be stopped by aft cover plate and switch to be parallel to tower face with decline liquid stream simultaneously by upwardly direction
Row further lifts prolonged action liquid stream rotation sky and horizontal force time, to promoting gas-liquid contact and impact mist to act on.Tower layer
Height is all mutually 40-70cm with tradition.
Manufacture material：Steel；Stainless steel, plastics, plastimets etc..The scope of application；Tower diameter 0.6-5.5m is (preferably
2-4.5m), normal pressure, room temperature.
Specific implementation mode：Oval ripple sieve-plate tower is that novel absorbent tower is by tower top, tower body, bottom of tower three parts group
At.Tower top is that gas vent is connect with pipe flange (see Fig. 1)；Here is demister；It is that inlet tube leads to Ta Nei simultaneously still further below
It is directly punched in the lower half portion of pipe；Tower body is often to save multilayer column plate staggered, master unit column plate is half ellipse by multiple tower sections
Circle ripple sieve tray (separate case) one is welded on steel pipe on the disk of garden by the semiellipse pipe of the long diameter 89-159mm punched and is equipped with 40-
60% hole；It is to weld one on 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 one,
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)《A kind of band screening
The downspout of flowing plate》-- it is that downspout lower part sets aft cover plate, aft cover plate is that the retroflect the tip of the tongue of shape goes out at liquid with column plate upwards in flat
Row；Being provided with multiple straight half circular holes below in descending liquid tube string makes liquid be flowed out in ridge shape；Liquid-bearing pan is not set on tower tray.Bottom of tower (see
Fig. 1) top is connected by flange with tower body, is air inlet pipe under connecting flange, into tower in top to the another side of import tower inner wall,
And it is provided with the hole that area is more than air inlet pipe sectional area in the middle and lower part for entering pipe in tower, hole distribution center should be with tower center phase
Together；It is outlet tube still further below, sewage draining exit is equipped in tower bottommost.Description of the drawings：Because the innovation of this patent is in tower body and tower
Top and bottom of tower do not have excessive emphasize.Fig. 1 is the assembling schematic diagram of round Wave screen plate tower, and wherein tower body is more piece multilayer, there is two
Critical piece is completely new：Column plate is《Semiellipse sieve pore ripple tray》；Downspout is《A kind of downspout with aft cover plate》；Tower
Nothing holds liquid zone on plate；Tower top, bottom of tower are to be formulated conventionally；Fig. 2 is《A kind of downspout with aft cover plate》Middle ligulate rolls over (screening) flowing plate
Schematic diagram；Fig. 3 is《Semiellipse sieve pore ripple tray》Schematic diagram.
Note：In figure by aft cover plate be denoted as baffle plate be in order to another kind《Ligulate sieve pore aft cover plate》It distinguishes.
