Description
Technical field
The utility model relates to pressure swing adsorption air separation plant, especially relates to a kind of adsorption tower.
Background technology
In the adsorption tower of variable-pressure adsorption equipment, compress molecular sieve to ensure that molecular sieve reduces the severity of wriggling when air separation plant normally runs as far as possible, reduce absorbent atomizing speed, multiple solution is proposed in prior art, adopt hold down gag more, but mode is various, useful filler compresses, to compress with spring assembly and by modes such as air cylinder device compressions, such as patent name is " molecular sieve compressing device of pressure swing adsorption air separation unit adsorption tower " (Authorization Notice No. CN l0l683582B), " N2 adsorption tower packing gravitational method nature hold down gag processed " (Authorization Notice No. CN 201454347U) by name etc. the structure disclosed in public technology.But in prior art, hold down gag all comes with some shortcomings, itself all there is compressibility in the medium (filler, spring, gas etc.) compressed, when causing hold down gag to work, steam-cylinder piston can be beated along with the pulsation of pressure medium in adsorption tower, cannot constant compacting screen cloth, when specification of equipment is larger, this situation is especially serious.
Summary of the invention
The utility model main purpose be to provide a kind of can constant compacting screen cloth, reduce the adsorption tower of absorbent atomizing speed.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of adsorption tower, and comprise and form tower body and the cylindrical shell of built-in sorbent, cylindrical shell two-port arranges upper cover, low head respectively, arranges lower distributor in low head; It is characterized in that: upper cover bottom is for circular, if envelope hides the screen cloth that cylindrical shell enters upper cover passage, screen cloth is provided with the compression packing layer piled up by stone or porcelain ball; Screen cloth periphery is fixed on upper cover, under external force, to arch upward or recessed tapered in the middle part of screen cloth.Screen cloth developed area be greater than fixed position area of section, so arch upward or recessed tapered in middle part, and not flattened structure of the prior art; Be convenient to effectively transmit the gravity compressing packing layer, and screen cloth arches upward or in recessed deformation process, can not the resistance of formation and modification, make the gravity of tight packing layer pass to adsorbent consistently, adsorbent is made to be subject to constant pressure, thus constant compacting screen cloth, reduction absorbent atomizing speed.
As preferably, compress packing layer and comprise screen cloth piles up and have several granular fillers, there is between filler the gap by gas.Be convenient to through air-flow.Described filler is stone or porcelain ball.Cost is low, not easily produces chemical reaction with medium and changes gravity, can keep long service life.
As preferably, upper cover bottom arranges screen cloth fixed support, and screen cloth fixed support comprises the annulus that two can clamp screen periphery, and two annulus consist of bolt and are fixedly connected with, and wherein an annulus is fixed on upper cover bottom.Rational in infrastructure, be easy to installation, dismounting, change screen cloth.
As preferably, screen cloth is covered with one deck outer screen, is provided with the joint pin of several rigidity between screen cloth and outer screen, the outer sheathed soft cover of joint pin, and joint pin and soft cover two ends are fixed on screen cloth and outer screen respectively; Compressing packing layer is filled between screen cloth and outer screen, outside soft cover.This structure, cavity in soft cover provides elastic space for compressing packing layer, avoiding compressing does not have unnecessary gap between the particle in packing layer and the phenomenon that forms caking, makes compression packing layer can rise at any time or decline all the time on screen cloth, can not produce the situation of insufficient space.
Therefore, the utility model have can constant compacting screen cloth, reduce the beneficial effect of absorbent atomizing speed.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is a kind of structural representations that upper cover adopts Double-layer screen structure.
Accompanying drawing 3 is a kind of structural representations of the screen cloth in Double-layer screen structure.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of adsorption tower of the utility model, as shown in Figure 1, it comprises formation tower body and the cylindrical shell 6 of built-in sorbent 11, and cylindrical shell 6 two-port arranges upper cover 4, low head 5 respectively, arranges lower distributor 8 in low head 5; Upper cover 4 bottom is circular, if envelope hides the screen cloth 10 that cylindrical shell 6 enters upper cover 4 passage, screen cloth 10 screen cloth is provided with the compression packing layer 12 piled up by stone or porcelain ball; Screen cloth 10 periphery is fixed on upper cover 4, under external force, to arch upward or recessed tapered in the middle part of screen cloth 10.Under external force, can move up and down in the middle part of screen cloth 10.
Upper cover 4 is connected with the discharge pipe of tool outlet 2, and low head 5 is connected with the feed pipe of tool import 1, feed pipe is connected with the blow-off line of tool sewage draining exit 3.
Compression packing layer 12 comprises accumulation on screen cloth 10 several granular fillers, has the gap by gas between filler.Filler is stone or porcelain ball.
Upper cover 4 bottom arranges screen cloth fixed support 9, and screen cloth fixed support 9 comprises the annulus that two can clamp screen cloth 10 edge, and two annulus are fixedly connected with by bolt formation, and wherein an annulus is fixed on upper cover 4 bottom.
In addition, during particle packing, when compressing packing layer rising or decline, particle usually needs space that is mobile or that rotate; The outline of adjacent particle is once agree with, interaction force integrally lumps making contiguous granulated, each particle is limited by adjacent particles and can not rotate, that is without saving space, particle will make freely to decline or to rise, compress packing layer also just limited, gravity effectively cannot be delivered to adsorbent layer, and being formed cannot the situation of compacting adsorbent.
Therefore, as the further improvement project of one, the utility model can adopt Double-layer screen structure, as shown in accompanying drawing 2, accompanying drawing 3, screen cloth 10 is covered with one deck outer screen 101, be provided with the joint pin 103 of several rigidity between screen cloth 10 and outer screen 101, the outer sheathed soft cover 102 of joint pin 103, joint pin 103 and soft cover 102 two ends are fixed on screen cloth 10 and outer screen 101 respectively; Compressing packing layer 12 is filled between screen cloth 10 and outer screen 101, outside soft cover 102.Cavity in soft cover provides elastic space for compressing packing layer, avoiding compressing does not have unnecessary gap between the particle in packing layer and the phenomenon that forms caking, make compression packing layer can rise at any time or decline all the time on screen cloth, the situation of insufficient space can not be produced, all the time constant compaction state is kept to adsorbent.
