Description
Technical field
The utility model relates to filtration and separation techniques field more particularly to a kind of hygiene-type rolling forward osmosis membrane components.
Background technique
Rolling forward osmosis membrane component, i.e. rolling forward osmosis membranes film core, it usually needs outside film outside fw frp film
Set, for accommodating and protecting rolling forward osmosis membrane component, when fluid passes through membrane component, membrane component is by compression swelling, glass reinforced plastic
Shape film can protect membrane component not because of compressive deformation.
When it is used, it needs to be installed in putamina, due to being had the gap between film core and putamina, need in its ATD
Sealing rubber ring is installed in the end of flow guiding disc, so that feed liquid flows through the feed liquid circulation road of film core as far as possible.But due to can only be in film
The water intake end of core fills sealing ring, this other end that will lead to film core does not seal so that the film core other end come out it is concentrated after
Feed liquid can enter the gap, cause corner or spot as yet untouched by a clean-up campaign.Simultaneously as glass reinforced plastic, in winding, glass reinforced plastic and membrane surface can not
It avoids having bonding place, also leads to a large amount of dead angle and exist.In cleaning link, not easy cleaning in these above-mentioned dead zones
Completely.
Utility model content
It is glass fibre reinforced plastics casing utility model aims to solve existing forward osmosis membranes, there are more health
Dead angle, difficult cleaning of problem.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of hygiene-type rolling forward osmosis membrane component, the membrane component include: to produce water central tube, forward osmosis membranes film
Bag, ATD flow guiding disc, film housing, the production water central tube are equipped with several flowing holes；
The forward osmosis membranes film bag is in long envelope shape, and has open end, and the open end of several film bags is bonded in production
The same circumferential position of water central tube, and successively winding is set to outside the production water central tube；Adjacent membranes bag is connected by binder
Positioning, to form feed liquid circulation road between film bag；
The ATD flow guiding disc is covered on the both ends for being wound with the production water central tube of forward osmosis membranes film bag, for feed liquid
It enters and leaves and carries out water conservancy diversion；
The film housing is latticed film housing made of hard plastic, and winds and be set to outermost forward osmosis membranes
Except film bag and ATD flow guiding disc, for accommodating and protecting the forward osmosis membranes film bag.
In a certain embodiment: flowed through in the forward osmosis membranes film bag and draw liquid, and be equipped with for draw liquid carry out
The first runner net of water conservancy diversion；It is additionally provided with second flow channel net in feed liquid circulation road between adjacent membranes bag, for carrying out water conservancy diversion to feed liquid.
In a certain embodiment: formed on the production water central tube it is several be drained through discharge orifice, the flowing hole of every row is along pipe
Axial equidistant arrangement.
In a certain embodiment: the edge of the outer surface of forward osmosis membranes film bag and perpendicular to winding axis center line on
Uniformly it is coated with the binder.
In a certain embodiment: the latticed film housing uses ABS material, and the thickness range of film housing is 300 μm-
3mm, mesh number are 50-150 mesh.
Compared to the prior art, permeable membrane device provided by the utility model has the advantage that using rigid plastics system
At latticed film housing, when fluid pass through membrane component when, membrane component be pressurized outward expansion, latticed film housing be able to be close to film
Shell and seal to concentrate, therefore do not need that traditional rubber seal is installed.Controllable fluid a small amount of simultaneously
Tangential flow bypass is formed between latticed film housing and putamina, prevents from forming flow blind angle and breeding the microorganisms such as bacterium.
In addition, such design also improves the cleaning and sterilization efficiency of membrane component, sanitation-grade requirement is realized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of permeable membrane device.
Specific embodiment
Fig. 1 is please referred to, the utility model embodiment provides a kind of hygiene-type rolling forward osmosis membrane component, the membrane component
It include: to produce water central tube, forward osmosis membranes film bag, ATD flow guiding disc, film housing, the production water central tube is equipped with several flowing holes.
In the present embodiment, formed on the production water central tube it is several be drained through discharge orifice, the flowing hole of every row is along the axial equidistant arrangement of pipe.
In specific structure, the forward osmosis membranes film bag is in long envelope shape, and has open end, the opening of several film bags
End is bonded in the same circumferential position for producing water central tube, and successively winding is set to outside the production water central tube.Adjacent membranes bag passes through
Binder connection positioning, to form feed liquid circulation road between film bag.Preferably, the edge of the outer surface of forward osmosis membranes film bag and
Perpendicular to winding axis center line on be uniformly coated with the binder.
In this way, feeding liquid water flow flows through on the outside of film bag, inside is then to flow through to draw liquid with more hyperosmosis,
Under the action of permeable pressure head, converge after the film bag for entering the hydrone in feed liquid on the inside of film by film outside into production water center
In pipe.The ATD flow guiding disc is covered on the both ends for being wound with the production water central tube of forward osmosis membranes film bag, for fixing film core end
Face does not allow film bag and latticed film housing to misplace because feed liquid is impacted, further, it is also possible to which the discrepancy to feed liquid carries out water conservancy diversion.
Further, the film housing is latticed film housing made of hard plastic, and is wound set on outermost
Except forward osmosis membranes film bag and ATD flow guiding disc, for accommodating and protecting the forward osmosis membranes film bag.Outside the latticed film
Set uses ABS material, and the thickness range of film housing is 300 μm of -3mm, and mesh number is 50-150 mesh.
Under the above configuration, the utility model is using latticed film housing made of rigid plastics, when fluid passes through membrane element
When part, membrane component is close to putamina and sealed to concentrate by compression swelling, latticed film housing, therefore is not needed installation and passed
The rubber seal of system.Controllable fluid a small amount of simultaneously is formed by tangential flow between latticed film housing and putamina
Road prevents from forming flow blind angle and breeding the microorganisms such as bacterium.In addition, such design also improves the cleaning and sterilization effect of membrane component
Rate realizes sanitation-grade requirement.
In preferred embodiment, it is equipped with to flow draw liquid and feed liquid inside and outside film sufficiently, in film bag for drawing liquid
Carry out the first runner net of water conservancy diversion.In addition, second flow channel net is additionally provided in feed liquid circulation road between adjacent membranes bag, for feed liquid
Disturbance and water conservancy diversion are carried out, viscous be set to of the second flow channel net produces on water central tube.
The above is only the preferred embodiment of the present invention, is not intended to limit its scope of the patents, all to utilize this
Equivalent structure transformation made by utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain is also included in the patent protection scope of the utility model.
