Description
Technical field
The utility model relates to a kind of vertical type module chemoattractant molecule sieve absorber, is mainly used in the space division system.
Background technology
In the space division system that is applied to fields such as petrochemical industry, natural gas, molecular sieve adsorber belongs to key equipment.During molecular sieve adsorber work, usually work, another regeneration, standby each other.In the process of regeneration, the excursion of the operating temperature of container reaches 150 ° more than the C, reciprocation cycle.Under given conditions, the effect of expanding with heat and contract with cold that this cycle occurs can produce alternate stress at internal tank, has worsened the force status of container, has increased design difficulty.
Distinguish from version, that molecular sieve adsorber mainly contains is vertical, horizontal, three types of radial flows.Wherein simple, the adsorption layer even flow field of vertical adsorber structure, dependable performance; Horizontal adsorber structure displacement volume is big, but force status is abominable, floor space big, need bear the easy fault rate height of complicated alternate stress, adsorption layer that expands with heat and contract with cold and cause; Radial flow adsorber structure complexity,, adsorption layer accident rate height high to the requirement of internals material.
Fig. 2 is vertical molecular sieve adsorber structural representation.In vertical absorber device, air-flow is distributed symmetrically in adsorption layer evenly, and the height of adsorption layer can freely be selected as required, so the function of adsorbent can be fully played.But, absorber is handled the increase of unstripped gas Capability Requirement along with technological process, the specification of absorber can be increasing, be mainly reflected in the increasing of the diameter of absorber, to increase the flow area of adsorption layer, but the increasing of its diameter is subjected to the restriction of traffic condition, so its displacement volume is restricted.Up to the present, vertical molecular sieve adsorber belongs to that manufacturing process is the most ripe, stress performance is best, the version that reliability is the highest, floor space is minimum.
Fig. 3 is horizontal molecular sieve adsorber structural representation, is the another kind of common form of molecular sieve adsorber.Horizontal absorber satisfies at diameter under the prerequisite of traffic condition, can increase the flow area of adsorption bed by adjusting the length of container, thereby the displacement volume geometric ratio of molecular sieve adsorber is increased.But horizontal absorber is when work, and its saddle support part force status is abominable, so thickness of shell strengthens; Because the influence of expanding with heat and contract with cold, second saddle support 7 can periodically come and go mobile, can produce corresponding alternate stress in the housing of container, and the resistance when its intensity and bearing move is suitable, need consider the fatigue rupture that this operating mode causes during design; Be subjected to the influence of geometry, its bed height is restricted, and adsorption efficiency is low; In mobile process, if the asynchronous generation of the distortion of the distortion of housing and adsorption bed, the accident that also can cause bed to leak.
The Chinese invention patent application that application number is 201010601631.0, name is called the compact adsorbent bed of modularization discloses a kind of adsorbent equipment of modularized design, and this adsorbent bed structure comprises a plurality of modularization adsorbent beds unit.There is following shortcoming in it:
1, a plurality of modularization adsorbent bed unit communicates in adsorbent bed, and shares the common gas passage that is built in adsorbent bed,
In actual applications, disturb big between a plurality of modularization adsorbent beds unit, the mass flow discrepancy of modularization adsorbent bed unit is even, the flow of modularization adsorbent bed unit, the place ahead is big, the flow of modularization adsorbent bed unit, rear is little, error is bigger, is unfavorable for early stage flow and the module number designing and calculating of carrying out according to demand.
2, this adsorbent bed is not suitable for vertical installation, needs horizontal installation, and is just illustrated in figures 1 and 2 as this patent application, also has numerous shortcomings of horizontal molecular sieve adsorber during work.
3, structure is comparatively complicated, has increased design and manufacturing cost.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and vertical type module chemoattractant molecule sieve absorber that a kind of reasonable in design is provided, this vertical type module chemoattractant molecule sieve absorber is on the design feature that keeps vertical molecular sieve adsorber, make the range of application of vertical adsorption structure expand main equipment to and get on, thereby can avoid labyrinth and the high accident rate of horizontal absorber, radial flow adsorber.
The technical scheme in the invention for solving the above technical problem is: a kind of vertical type module chemoattractant molecule sieve absorber, comprise upright shell, form sealed cavity in the upright shell, it is characterized in that: in described upright shell at least one adsorption module is installed, described adsorption module is made up of raw material gas inlet, product gas outlet, adsorption layer, plural adsorption module upper and lower settings, each adsorption module parallel operation; Separated by the branch chamber end socket that is fixed in the upright shell between two adsorption modules, branch chamber end socket is separated into not connected sealing separate space up and down with described sealed cavity, and each adsorption module is all corresponding with a sealing separate space; The adsorption layer of an adsorption module is fixed in the sealing separate space, and raw material gas inlet and the product gas outlet of this adsorption module are fixed on the upright shell, and communicate with the sealing separate space.
The raw material gas inlet of adsorption module described in the utility model and product gas outlet are fixed on the side of upright shell.
The utility model fixedly has skirt in the bottom of described upright shell.
The utility model compared with prior art has following advantage and effect: the utility model carries out modularization to adsorption structure, and these adsorption module stacks are installed, and has kept the vertical structure of vertical molecular sieve adsorber; But because adsorption module parallel operation, so its adsorption capacity is unrestricted, its adsorption capacity is directly proportional with the quantity of module in theory, select the quantity of adsorption module to get final product according to the requirement of its displacement volume, and the time spent is done in the operating temperature cyclically-varying of each adsorption module, the effect of being expanded with heat and contract with cold, its internal stress is loaded with self always and is equated, so can not produce corresponding alternate stress; This structure has kept the advantage of vertical absorber, has solved the restricted problem of its displacement volume again, has avoided the labyrinth of horizontal adsorption layer and radial flow adsorption layer simultaneously.
