Description
Technical field
It the utility model is related to field of water treatment equipment, and in particular to a kind of big flux rolling EDI components.
Background technology
At present, EDI electricity demineralizer mainly includes board-like EDI and rolling EDI.Traditional coiled EDI mainly passes through top cover
Realize and seal with bottom, single branch membrane module normal flow is in 2m3/ h or so, installed and used under same water outlet requirement take up an area it is larger,
Low space utilization, ton water cost is higher, while needs to be assembled using forcing press when filling film core, production operation requirement compared with
It is high.
Traditional plate and frame EDI is compared to, rolling EDI has concentric-ring pattern Electric Field Distribution, and current efficiency is higher, and power consumption is more
It is low；The dense of rolling EDI, the design of fresh water fluidised form design different from traditional plate and frame EDI co-flow, can preferably eliminate and draw
Play the factor of fouling.Meanwhile rolling EDI structure design creates dense, fresh water flow passage unit from outside to inside, water quality can be regarded
Situation configures different resins in same EDI components, can not only improve desalting efficiency, can also effectively reduce deionization institute
The energy consumption needed.
But rolling EDI is that tubular membrane stack is rolled into anion and cation exchange membrane by some, then respectively in dense, fresh water stream
Filling ion-exchange resin in road, is finally completed plus bottom end cover encapsulation, and water and commencement of commercial operation process are tried in rolling EDI components
In, due to the chance of amberplex and ion exchange resin it is water-swellable the characteristics of, it is desirable to it is right in rolling EDI component assembling process
The concentricity requirement of membrane stack is higher, to ensure whole component in circumferencial direction even inflation, it is ensured that the sealing of component.It is but actual
Situation is, due in whole tubular membrane stack, circumference axially with the amberplex of longitudinal each point and the chance water of ion exchange resin
Swellability has differences, and this species diversity is relevant with amberplex and ion exchange resin material itself, is also assembled with rolling EDI
The precision of process is relevant.The direct result of this species diversity is exactly to cause rolling EDI component leaks, and component internal is dense, fresh water
Crossfire, component desalting effect is had a strong impact on, until whole component is scrapped.Therefore, prior art is badly in need of wanting at a kind of single component
Reason amount（Flux）Rolling EDI subassembly products that are big and can running reliably and with long-term.
Utility model content
The purpose of this utility model, it is to solve the problems, such as in background technology, there is provided a kind of big flux rolling EDI groups
Part.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of big flux rolling EDI components, including：Shell and film core, the shell include, shell body, sealing shroud and lid

Sealing ring, the 3rd sealing ring is provided between the sealing shroud and the end cap.
EDI membrane modules sealing means at present, predominantly directly sealed at the both ends of film core by covering, in assembling process
In, it is necessary to use forcing press and very high to the concentricity requirement of all parts, the process of shell is inserted in using forcing press in film core
In, the frictional force of sealing ring and shell is very big, and during this is inserted in, sealing ring can be damaged significantly, no
Beneficial to the permanent sealing effectiveness of component.In addition, in actual practical process, the exchanger resin due to film core inner is using process
Middle needs are constantly regenerating, and process of this regeneration is typically uneven, so using in practice, membrane module interior point
Swelling stress skewness, so as to cause film core to produce non axial bending force, and the sealing means of conventional closure can only
Reach axially apply sealing force effect, therefore traditional membrane module list branch diameter generally in below 40cm, once exceeding this number
Value, the membrane module of conventional closure sealing easily leak after long-term use, influence desalination effect.
The technical program is by said structure, in assembling process, it is not necessary to using forcing press, and sealing ring when assembling
It will not over long distances be rubbed with shell body, ensure that the reliability of sealing ring.In addition, during membrane module long-term use, by
In shell body, sealing shroud and cover plate be a three-layer sealed structure, when exchanger resin produce irregular deformation when, shell body
Non axial change can occur for the spacing between sealing shroud, i.e., the uneven change of the distance of each point between shell body and sealing shroud
Change and shell body is no longer overlapped with the axial direction of sealing shroud, similarly, it is also possible that changing between sealing shroud and end cap, and
Under the collective effect of first sealing ring, the second sealing ring and the 3rd sealing ring, the generation of leakage is avoided.Therefore the film group of this programme
Part, the requirement to axial seal is reduced, reduce the difficulty and cost of production.
