Description
Technical field
Reverse osmosis membrane assembly is the utility model is related to, is removed for impurity such as organic matter in water body and inorganic salts.It can be used for
Clean water treatment technology, the highly concentrated technique of high-salt wastewater, high organic wastewater and remaining industrial wastewater.More particularly to one kind is opened
Put formula webmaster runner reverse osmosis membrane assembly.
Background technology
In recent years, membrane technology is quickly grown, and is returned in electric power, metallurgy, petroleum and petrochemical industry, medicine, food, municipal works, sewage
With and the field such as desalinization obtain relatively broad application, all kinds of engineerings are even more rapidly to the demand of membrane technology and its equipment
Increase.It has been widely used at present in percolate and strong brine zero-emission application field, network pipe type reverse osmosis membrane assembly.
But common network pipe type membrane module has following defect, the utility model is on the basis of existing network pipe type membrane module
It is correspondingly improved：
（1）160 kilograms of traditional super-pressure network pipe type membrane modules to surpass using expensive 316Ti Stainless steel pressure vessels
The popularization of High-Voltage Network tubular membrane component is restricted.In addition traditional 316Ti Stainless steel pressure vessels are meeting during waste water
There is phenomenon of getting rusty, and then shorten the life-span of super-pressure network pipe type membrane module.
（2）Traditional network pipe type membrane module uses the open runner of scalariform, open water inlet filter point thick filter and thin
Filter（Fig. 1）, current enter in air stream enter runner with thin filter angle in 90 ° at work.The current of larger resistance are formed in passage, because
Suspended particulate substance and organic matter in this water inlet cause the dirt of film to be blocked up in being easily attached into water filter.In addition, the concentration of inorganic salts
On the surface of film because concentration polarization easily forms fouling.Larger resistance can cause the larger pressure loss in water inlet filter, when
When the pressure loss is higher than 1 kilogram, because resistance to stress disk and the weaker bonding of center penetrating fluid collecting pipe can cause resistance to stress disk edge
Center penetrating fluid collecting pipe to slide.The mobile rupture that can cause membrane component epoxide-resin glue shell of resistance to stress disk, eventually
Trigger the damage of water inlet filter and film bag.In addition, the dirty stifled and concentration polarization of film can cause the decline of membrane flux, the film longevity is ultimately resulted in
The shortening of life.
（3）Its center ring of the resistance to stress disk of traditional network management formula membrane module is connected support chip with outer interannular and connected using straight chip type
Connect, form sector channel between support chip and piece, current can not be mixed uniformly during water inlet, and can not be with the gradual change of circumference membrane area
And distribute in right amount, therefore water inlet can not evenly distribute to different circumference to intake tunnel in, be easily caused part film channel blockage.This
The inwall of its center ring of the resistance to stress disk of outer traditional network pipe type membrane module does not have safety locking mechanism, therefore easily causes resistance to stress
Disk slides along center penetrating fluid collecting pipe, eventually leads the damage into water filter and film bag.
（4）Traditional flow guiding disc water inlet enters from straight hole due to lacking radian, current, causes to be uniformly distributed in into water
The intake tunnel of membrane component, therefore, it is easily caused part film channel blockage.Sealing ring on the mozzle of center is by holding tightly in sealing
The mode of heart mozzle is sealed.This sealing means are easily caused drainage, and then deteriorate producing water water quality.Long-term leak
Stainless steel center pull rod can be caused to corrode.

1. efficient open webmaster runner reverse osmosis membrane assembly does not use stainless steel center pull rod（Referring to the patent No.）, and
Open runner network pipe type high pressure reverse osmosis membrane assembly（STRO）Using stainless steel center pull rod, the open runner webmaster of super-pressure
Formula reverse osmosis membrane assembly（STRO）Not only use stainless steel center pull rod but also used 4 peripheral pull bars, so that new film
The operating pressure of component rises to 90 kilograms and 160 kilograms respectively by original 75 kilograms.
2. when the salt content of raw water is in 25000-30000 mg/l, the other efficient open webmaster of traditional 75kg weight category
Runner reverse osmosis membrane assembly, due to relatively low operating pressure, the rate of recovery of system would generally be limited in 50% or so.And use
The open runner network pipe type high pressure reverse osmosis membrane assembly of 90 kilograms of ranks and the open runner webmaster of the other super-pressure of 160 feather weight
Formula reverse osmosis membrane assembly, the rate of recovery of system can rise to 60% and 80% or so respectively, so as to which the cycles of concentration of system be risen to by 2
5. the higher rate of recovery reduces the yield of system concentrated water, therefore reduces the treating capacity of subsequent evaporation device, thus can drop significantly
The investment cost and operating cost of low system.Relatively low operating pressure causes the aquifer yield of film relatively low, thus in the production water of system
The quantity of required membrane module is higher in the case that amount is certain, thus the cost of investment of system is higher.And super-pressure reverse osmosis membrane group
Part can overcome higher osmotic pressure, because intake pressure raises the net pressure rise for causing driving counter-infiltration so that production water
Amount increases, and then reduces the quantity of membrane module, so as to reduce the investment of system and operating cost.
3. when the operating pressure rise of reverse osmosis membrane, film also increases to the rejection of salinity.Because permeation flux
Increase with the rise of operating pressure, as the pressure increases, the quantity of solvent of permeable membrane increases and flux salt is constant, therefore salt rejection rate increases
Greatly.
4. when the salt content of raw water is in 25000-30000 mg/l, the open runner network pipe type high pressure of 75kg weight category is anti-
Permeable membrane element（STRO）（Non-stop layer pull bar）, the open runner network pipe type high pressure reverse osmosis membrane assembly of 90 feather weight（STRO）And
The open runner network pipe type reverse osmosis membrane assembly of super-pressure（STRO）Test data of experiment such as following table:
| Raw water salt content 25000-30000 mg/l | The system rate of recovery | Salt rejection rate | Membrane flux |
| The other STRO of 75kg weight category | ̴50% | 95% | 10LMH |
| 90 kilograms of rank STRO | ̴60% | 95.8% | 12LMH |
| 160 kilograms of rank STRO | ̴80% | 95.9% | 15LMH |
