1）Sprial roll type membrane separator.The separating film element of this separator mainly by Separation membrane, infiltration conductance spread,
Water inlet flow-guiding cloth, center collector pipe and sealing glue are formed；Required when production according to size, cut required original
Material, several pages are cut into by Separation membrane（Differed from page 2 to page 100）, then will be removed with sealing glue and be connect with center collector pipe
The other three direction sealing outside one end is touched, and is rolled up on the collector pipe of center, so each film page must be in three of them direction
Upper sealing, and one whole diaphragm is also cut into multiple film pages, a film bag is formed after each film page sealing, so common spiral shell
Rotation wound membrane element is multimembrane page multimembrane bag structure.
Common spiral wound film element effectively more than 1 square meter of membrane area uses multimembrane page multimembrane bag structure.So
Spiral wound film element need using many fluid sealants and diaphragm utilization rate and effective membrane area it is lower, permeate tolerance
It is not high；Simultaneously because longitudinal runner length of film（Generally 400-800mm）, it is easy to concentration polarization is formed, seriously affects film
Separating property, causes separative efficiency to reduce.And traditional spiral wound membrane can not make short runner membrane separator.
2）Disc-type membrane separator.This membrane separator is made of multiple film bags, and the center of film bag is provided with centre bore, multiple
To overlap behind sealing ring interval between film bag, it is overlapping after multiple film bags be centrally formed central passage；Central passage
Both ends be respectively equipped with connecting tube；The film bag is successively by plate membrane, non-woven fabrics support chip, support flow-guiding screen, non-woven fabrics branch
Blade and plate membrane totally five layers of composition, support flow-guiding screen therein are equipped with gasket in central hole, and the edge of film bag is by five layers of material
Material is hot pressed into sealing strip.
The diaphragm utilization rate of this disc-type membrane separator is low, is cut by plate membrane and makes circular film unit, diaphragm
Corner loss amount it is very big, while be required to inside and outside bonding per a piece of diaphragm in diaphragm bonding process, lose many effective film surfaces
Product；Air inlet at the same time moves direction part with permeating airflow and is co-current flow, is partly counter-current flow, and co-current flow part therein
Membrane separation efficiency can be reduced.Therefore the reduction of overall separative efficiency is caused.
In summary, it is now desired to which one kind being capable of solution to the problems described above or device.
The content of the invention
The utility model is to solve the above-mentioned deficiency present in the prior art, proposes that one kind is simple in structure, design is skilful
It is wonderful, the concentration polarization in separation process can be avoided and increase substantially the collapsible membrane separator internals of separative efficiency.
The technical solution of the utility model is：A kind of efficiently collapsible membrane separator internals, it is characterised in that：It is described
Separator internals include the deflector 1 of cavity structure, one end of deflector 1 is provided with connecting tube 2, the side of 1 both sides of deflector
A plurality of infiltration conductance chute 3 is offered on wall, while the both sides of deflector 1 are additionally provided with support plate 4, and the axis of support plate 4
To axially in parallel with deflector 1, multiple seperation film bags 5 for stacking setting, phase are respectively arranged with the upper and lower surface of support plate 4
Air inlet flow-guiding screen 6 is both provided between two adjacent seperation film bags 5, infiltration conductance drift net is both provided with each seperation film bag 5
7, and the opening of all seperation film bags 5 connects with infiltration conductance chute 3, and in the opening and infiltration conductance of seperation film bag 5
The junction of chute 3 is also equipped with fluid sealant.
The utility model compared with the existing technology, has the following advantages that：
The efficient collapsible membrane separator internals of this kind of structure type, fundamentally change in traditional membrane separator core
The structure of part, using the form of multiple seperation film bags mutually stacked, can greatly shorten per-meate side gas and walk in film bag
Distance, so as to avoid the concentration polarization problem produced in separation process, while gas can directly pass through any one seperation film
Bag carries out separating treatment, can effectively improve utilization rate, effective membrane area and the infiltration tolerance of diaphragm, greatly improve gas separation
Efficiency.And its manufacture craft is simple, manufacture is of low cost, it can be said that it possesses a variety of advantages, particularly suitable for
Promote and apply in the art, its market prospects is very wide.
Brief description of the drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the side view of the utility model embodiment.
Fig. 3 is the partial enlarged view for the seperation film bag that state is stacked in the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.As shown in Figure 1, Figure 2, Figure 3 shows：It is a kind of efficient
Collapsible membrane separator internals, it includes the deflector 1 based on one, and the inside of this deflector 1 is cavity structure,
One end of deflector 1 is provided with connecting tube 2, while a plurality of infiltration conductance chute 3 is offered on the side wall of 1 both sides of deflector,
And the both sides of deflector 1 are additionally provided with support plate 4, the two support plates 4 are horizontally disposed, and its axial axial direction with deflector 1
It is parallel, it is respectively arranged with multiple seperation film bags 5 for stacking setting, adjacent two seperation film bags 5 in the upper and lower surface of support plate 4
Between be provided with air inlet flow-guiding screen 6, and infiltration conductance drift net 7 is both provided with each seperation film bag 5, and all seperation film bags
5 opening connects with infiltration conductance chute 3, is also equipped with the opening of seperation film bag 5 and the junction of infiltration conductance chute 3 close
Sealing.
The course of work of the efficient collapsible membrane separator internals of the utility model embodiment is as follows：The present apparatus is installed on
In membrane separator, membrane separation is carried out to gas, the mixed gas in the outside of seperation film bag 5 is contacted with the surface of seperation film bag 5
Afterwards, under the action of the seperation film of seperation film bag 5 is formed, the object gas in mixed gas can enter the inside of seperation film bag 5,
And remaining gas is then blocked in outside seperation film bag 5, since the gap between adjacent seperation film bag 5 relies on air inlet flow-guiding screen
7 prop up, therefore can ensure that all seperation film bags 5 can be contacted fully with mixed gas, so as to ensure that effectively
Membrane area；Infiltration conductance drift net 8 is also both provided with the inner cavity of each seperation film bag 5 at the same time, seperation film bag 5 is fully supportted
Rise, so as to ensure the effect of gas flowing；This structure type, can effectively improve utilization rate, the effective film surface of increase of diaphragm
Product, increase infiltration tolerance；
It can be entered into the object gas after seperation film bag 5 by permeating conductance chute 3 in the inner cavity of deflector 1, and most
Discharged, collected in the container of object gas by connecting tube 2 eventually；
In the present apparatus, for each seperation film bag 5, into seperation film bag 5 after gas need traveling it is maximum away from
From the width of as seperation film bag 5, for the present apparatus compared with conventional separators internals, the characteristics of it is maximum is exactly to substantially reduce to ooze
The travel distance of saturating side gas, therefore can fundamentally prevent the concentration polarization problem produced in separation process.
