Description
Technical field
This utility model relates to gas separation equipment field, is specifically related to a kind of adsorption tower.
Background technology
As a example by space division field, the most conventional air separation employing is membrane separation technique and pressure swing adsorption (abbreviation
PSA).Film cylinder is the critical piece of membrane separation plant, and the membrane separation plant of film cylinder composition, compared with PSA nitrogen, oxygen generating plant, has
There are the advantages such as simple in construction, volume are little, switch valve is few, increase-volume is convenient.Film cylinder is made up of some hollow-fibre membranes, doughnut
Film has different permeabilities to nitrogen and oxygen, and therefore oxygen and nitrogen are separated.Doughnut external diameter 0.4-2.0mm,
Internal diameter 0.3-1.4mm, is very easy to blocking, and therefore film cylinder purity requirements compressed-air actuated to prime is higher, and this increases virtually
Having added the cost of investment of equipment, in actual motion, the film cylinder life-span, the life-span was shorter typically at 2-3, and film cylinder fully rely on into
Mouthful, expensive, the delivery cycle is long, considerably increases again operation maintenance cost.Adsorption tower is the capital equipment of PSA, adsorption tower
Internal filling molecular sieve, utilizes the rate of adsorption that molecular sieve is different with nitrogen to oxygen, separating off nitrogen under pressure swing adsorption
Gas and oxygen.Fill the adsorption tower life-span length of molecular sieve, low cost, and aerogenesis purity range is wide, but adsorption tower size is general
Relatively big, entirety is the heaviest, changes difficulty.Wanting to seek one at present with low cost, life-span length has again film cylinder advantage concurrently simultaneously
Adsorption tower.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above, it is provided that the adsorption tower of a kind of alternative film cylinder, has film simultaneously
Cylinder and the advantage of PSA adsorption tower.A kind of adsorption tower of alternative film cylinder, by upper cover, lower capping, O or pad, cylinder,
Air distributor, lower sieve plate assembly, upper sieve plate, spring, air inlet/outlet joint form, it is characterised in that adsorption tower two ends are respectively
Being connected with cylinder with capping, set conical flow distributor in lower capping, air distributor top is lower sieve plate assembly, lower sieve plate group
Part is made up of lower sieve plate and metal gauze, and lower bolt for sieve plate is fixed on cylinder bottom, filling adsorbent, cylinder top in cylinder
For movable upper sieve plate, upper sieve plate top is spring, topmost closes with upper cover, and upper and lower cap central offers air inlet respectively
And gas outlet, air inlet/outlet is female adapter, or male connection.
Described conical flow distributor top closure, giving vent to anger in side, fully breaks up air-flow, it is ensured that air-flow consistent ground
Enter adsorption tower.
Inner barrel is circular, and cylinder profile is cylindrical or oval or square or rectangular shape.
Within cylinder interior diameter is limited in 150mm, interior length controls within 1700mm, and total measurement (volume) is less than 30L, is not related to
Pressure vessel, it is not necessary to national special supervision, can batch machining, large-scale production.
Flange form is made in adsorption tower capping, by bolt, O and cylinder fixing seal, or makes I.S.S, with
Cylinder is threadably secured.
The material of described O is various synthetic rubber, natural rubber or politef, and gasket material is asbestos
Rubber blanket or metal wound gasket or graphite pads or politef pad, described connecting bolt be interior hexagon,
Or outer-hexagonal shape or semicircle or be dormant bolt.
Cylinder, cover plate, air distributor and sieve plate use cemented carbide aluminum or highstrenghtpiston or stainless steel
Material or carbon steel material.
Spring is helical spring or is cone shaped spring.
This utility model can be used for THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE, THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE, pressure swing adsorption hydrogen production equipment, change
Pressure absorption decarbonation appliances etc. are conventional utilizes pressure swing adsorption and the gas separation equipment of temp.-changing adsorption technology.
The beneficial effects of the utility model are: this utility model develops a kind of light-duty absorption with air distributor
Tower, simple in construction, difficulty of processing is little, is not related to pressure vessel, can be separately as the equipment of making nitrogen, oxygen generating plant, hydrogen producer etc.
The adsorption tower of pressure varying adsorption gas separating equipment uses.In the increase and decrease present invention, the quantity of adsorption tower, changes the product of equipment accordingly
Can, conveniently, service life is long for dismounting, increase-volume.This utility model can realize standardization, scale makes, and reduction manufactures and designs
Cost, shortens the production cycle, and on the other hand, this adsorption tower volume is little, lightweight, and internal adsorbent is easier to the densification filled
Consolidation, substantially increases the adsorption efficiency of adsorbent.
