Description
Technical field：Chemical industry；Environmental protection；Gas is absorbed, washing, is sprayed, VOCs is administered
Background technology：The gas that packed tower is widely used in petrochemical industry field of environment protection is absorbed, washing, is sprayed, VOCS processing
In, but when handle large-minded required tower diameter it is big when, column efficiency degradation can be made because gas-liquid is unevenly distributed；In addition
Packed tower also has the defects of pressure drop is big, entrained liquid is serious.In big tower diameter, plate column is inevitable choice, at present gas
The alternative big treating column in absorption field is seldom.This patent has selected efficient ellipse head sieve pore cap plate tower, this tower
Plate is because being equipped with downflow 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 is dropped than with high
Packed tower is small, and the empty tower gas velocity of permission is more high than the packed tower of same diameter.Yin Tanei《Oval sieve pore cap column plate》-- this
The patent that inventor is applying is (to not only increase mass transfer effect with column plate plan view for non-vertical direction in most sieve pores
Rate 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
Body distributor, therefore liquid distribution trough is not set separately.Therefore the tower no liquid distributor therefore liquid of structure are gone directly bottom of tower by tower top,
Reducing has many places inlet tube-partially liq flow of liquid distribution trough short, therefore the washing effect in same amount of liquid is notable
It improves, is used in downspout《A kind of band hides the downspout of liquid plate》The patent that the present inventor is applying.This patent with just
The tray absorption columns used, which are compared, has contact area about 20%, and most of is that non-vertical planes contacts -- greatly reduce
The generation of idle work entrainment, is one of the present inventor's tower series new idea.
A kind of completely new tray absorption columns of invention content ellipse head sieve pore cap plate tower, are by tower top, tower body, bottom of tower
Three parts form, wherein the tower body for most influencing efficiency is completely new.The present invention 1 is to use for the first time《Oval sieve pore cap column plate》
It is to be welded on the disk of garden distance between the ellipse head of each punching by the ellipse head punched that (separately applying), which is master unit-,
40% or more hole is equipped with for 0.6-1.0 times of (being not less than 50mm) steel plate of aperture R outside end socket, the internal diameter of tower tray is slightly less than tower
Internal diameter (an arc string has been lacked on tower tray) vacancy arc string of about 10% tray area is downflow weir -- it is to be welded on tower tray string
Connect a baffle perpendicular to tower tray, baffle of the baffle top higher than tower tray plane 40-70mm (being known as liquid holdup) in tower tray lower end
There is open area on about 1/2 downflow weir to be equipped with porous arch to lower piece of column plate discharge weir top equal-height position；2, it is to use for the first time
The patent that the present inventor is applying《A kind of downspout with aft cover plate》The downspout sets screening (folding) flowing plate in lower part, hides
Flowing plate is that the retroflect the tip of the tongue of shape goes out at liquid with column plate upwards in parallel；Being provided with multiple half circular holes below in descending liquid tube string makes liquid
Body is flowed out in ridge shape；3, do not set and hold the gas liquid interfacial area that liquid zone not only increases 10%, also make to hold the air-flow of liquid zone rising by
Aft cover plate stops and switchs to be parallel to tower face and decline liquid stream by upwardly direction further to lift the rotation of prolonged action liquid stream parallel
Empty and horizontal force；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 (excellent
Select 2-4.5m), normal pressure, room temperature.
Specific implementation mode：The absorption of ellipse head sieve pore cap plate is made of tower top, tower body, bottom of tower three parts.Tower top
(see Fig. 1) is that gas vent is connect with pipe flange；Here is demister；It is that inlet tube leads to Ta Nei and in pipe still further below
It directly punches lower half portion.Tower body is often to save multilayer column plate staggered by multiple tower sections, and master unit column plate is《Ellipse head
Sieve pore cap column plate》(separate case)-is welded on by the ellipse head of the DN80-150 punched and each on the disk of garden is equipped with porous oval seal
Distance is that the 0.6-1.0 times of steel plate of the outer aperture R of end socket is equipped with 40% or so hole between head, and the internal diameter of tower tray is slightly less than in tower
Diameter (an arc string has been lacked on tower tray) vacancy arc string of about 10% tray area is downflow weir -- it is to be welded on tower tray string
One perpendicular to tower tray baffle, baffle top is in tower tray lower end higher than tower tray plane 40-70mm (be known as liquid holdup)《It is a kind of
Downspout with aft cover plate》-- the downspout lower part sets screening (folding) flowing plate, aft cover plate be retroflect shape the tip of the tongue go out upwards at liquid with
Column plate is in parallel；Being provided with multiple 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；
The bottom of tower top (see Fig. 1) is connected by flange with tower body, is air inlet pipe under connecting flange, into tower in top arrive the another side of import
Tower inner wall, and enter tower in pipe middle and lower part be provided with area be more than air inlet pipe sectional area hole, pore size distribution center is answered
It is identical as tower center.It is outlet tube still further below, sewage draining exit is equipped in tower bottommost.
Description of the drawings：Fig. 1 is the assembling schematic diagram of ellipse head sieve pore cap plate tower：Wherein tower body is more piece multilayer, there is two
A critical piece is completely new：Column plate is《Ellipse head sieve pore cap column plate》；Downspout is《A kind of descending liquid with aft cover plate
Pipe》；Nothing holds liquid zone on column plate；Tower top and bottom of tower are to be formulated conventionally；Fig. 2 is aft cover plate schematic shapes -- the downspout lower part
If hide (folding) flowing plate, aft cover plate be retroflect shape the tip of the tongue go out upwards at liquid with column plate be in it is parallel；Descending liquid tube string is opened below
There are multiple half circular holes that liquid is made to be flowed out in ridge shape；Fig. 3 is column plate schematic diagram -- it is to be welded on circle by being equipped with porous ellipse head
It is each to be equipped with the 0.6-1.0 times of steel plate that distance between porous ellipse head is the outer aperture R of end socket and be equipped with 40% or so on disk
Hole.
Note：In order to distinguish with《Ligulate sieve pore downspout》In aft cover plate it is different, in Fig. 2 marks being known as folding (screenings) flows
Plate.
