Description
Technical field
UF membrane field is the utility model is related to, more particularly to a kind of forward osmosis membrane module.
Background technology
Concentration process is the step of feed separation, water treatment field frequently encounter, and concentration technology main at present mainly has：
Distillation, nanofiltration（NF）, counter-infiltration（FO）Deng, but these methods there is also following deficiency：Way of distillation concentration needs to expend greatly
The energy is measured, cost is too high.Counter-infiltration（RO）Or nanofiltration（NF）It is a kind of effective ways of gathering trace ion, but by osmotic pressure
Influence, its enrichment cycles of concentration is limited, and energy consumption is also higher.
Forward osmosis（FO）It is a kind of new isolation technics, is described as low energy consumption of new generation, low stain, sustainable development
Desalination and new energy technology.Positive osmosis device be using the other principle of permeable pressure head carry out be dehydrated separation equipment, equipment
Core be forward osmosis membranes, the both sides of film are respectively the gateway of two groups of feed liquids of different osmotic.Water is from osmotic pressure
Low side enters the high side of osmotic pressure, and the transit dose within the regular hour is able to weigh and considers the membrane area of equipment both
The infiltration membrane flux of the process can be calculated.Comparatively speaking, the cycles of concentration of forward osmosis concentrator more than counter-infiltration and
Nanofiltration is high, and forward osmosis can carry out feed liquid concentration at normal temperatures, and this is one greatly progressive compared with evaporation technique.It is existing
Forward osmosis membrane module find to be less than theoretical water flux due to the presence of concentration polarization phenomenon, actual water flux in use.
The content of the invention
In view of the above-mentioned problems, the purpose of this utility model is that concentration polarization phenomenon can effectively be solved by providing one kind, be carried
For the forward osmosis membrane module of positive osmotic water flux.
To reach above-mentioned purpose, the technical scheme that the utility model is proposed is：A kind of forward osmosis membrane module, including just
To infiltration diaphragm, it is characterised in that：Also include bearing plate and lower bearing plate on one, described upper bearing plate side is entered provided with feed liquid
Mouthful, opposite side is provided with material liquid outlet, and described upper bearing plate is corrugated provided with liquor inlet is connected with material liquid outlet
Feed liquid fluid passage；Described lower bearing plate side, which is provided with, draws liquid import, and opposite side, which is provided with, draws liquid outlet, is held under described
Pressing plate be provided with by draw liquid import and draw liquid export be connected corrugated draw fluid path；Described forward osmosis
Film is located between upper bearing plate and lower bearing plate, and upper bearing plate, lower bearing plate are provided with sealing ring, by forward osmosis membranes surrounding
Sealing is fixed；It is connected between described upper bearing plate and lower bearing plate.
Preferably, it is designed with rhombus between described upper bearing plate and forward osmosis membranes, lower bearing plate and forward osmosis membranes
Deflector.
Preferably, being fixedly connected with mode between described upper bearing plate and lower bearing plate is：Described upper bearing plate is with
Bearing plate is surrounded by corresponding bolt hole, is connected between described upper bearing plate and lower bearing plate by bolt with nut
It is fixed.
Using above-mentioned technical proposal, forward osmosis membrane module described in the utility model, have the advantage that for：
1) by the design of upper and lower bearing plate, make forward osmosis membranes assembling components convenient；
2) runner is provided with waveform, can alleviate concentration polarization phenomenon with liquid turbulization phenomenon, reduces film dirt
Dye, improves membrane flux, extends filtration time；
3) increase rhombus deflector, further turbulization image, improve filtration flux and extend filtration time.
Brief description of the drawings
Fig. 1 is forward osmosis membrane module exploded view described in the utility model；
Fig. 2 is forward osmosis membranes assemble cross-section described in the utility model；
Fig. 3 is forward osmosis membrane module stereogram described in the utility model.
Embodiment
With reference to the accompanying drawings and detailed description, the utility model is described further.
As Figure 1-3, forward osmosis membrane module described in the utility model, including forward osmosis diaphragm 40, upper pressure-bearing
Plate 10 and lower bearing plate 20, the upper side of bearing plate 10 are provided with liquor inlet 101, and opposite side is provided with material liquid outlet 102, upper bearing plate
10 are provided with the corrugated feed liquid fluid passage 103 that liquor inlet 101 is connected with material liquid outlet 102；Lower bearing plate 20 1
Side is provided with and draws liquid import 201, and opposite side, which is provided with, draws liquid outlet 202, lower bearing plate 20 be provided with will draw liquid import 201 with
That draws that liquid outlet 202 is connected corrugated draws fluid path 203；Forward osmosis membranes 40 are held located at upper bearing plate 10 with
Between pressing plate 20, and upper bearing plate 10, lower bearing plate 20 are provided with sealing ring 50, by 40 fixation sealed around of forward osmosis membranes；
It is simultaneously upper to be designed with rhombus deflector 30 between bearing plate 10 and forward osmosis membranes 40, lower bearing plate 20 and forward osmosis membranes 40；
In addition, lower bearing plate 20 is surrounded by vertically disposed bolt hole 204, upper bearing plate 10 is surrounded by corresponding bolt hole
