Description
Technical field
The present invention relates to liquid filtration art, and in particular to a kind of filtering film component and its filter of composition.
Background technology
Filtering film component of the prior art is mostly plate armature or tubular structure, filtering film component of the prior art
Due to the limitation of self structure, exist when in use operating pressure is big, yields poorly, needs fluid passage greatly, wash away flow
Greatly, the power consumption of pump is higher, and thus causing filtering film component, filter effect is undesirable in use, the filter being made up of it
Filter effect it is also bad.
The content of the invention
Present invention is primarily aimed at a kind of filtering film component is provided, to solve filtering film component filtering effect in the prior art
The undesirable technical problem of fruit.
Filtering film component of the present invention, including membrane component, including membrane component, the membrane component are made up of porous metal film
The hollow structure of one side opening, in addition to it is covered in the turbulent flow grid structure outside membrane component.Porous metal film possess with its
Lower filtration resistance under the equal filtering accuracy of his film, bigger filtration flux；When liquid is by membrane component in the present invention, by
In the special mesh-structured design of turbulent flow grid structure, strong turbulent flow whirlpool can be produced when liquid flows through turbulent flow grid, can be right
Film surface forms washing away for continuous and effective, peels off the pollutant for being attached to film surface.Meanwhile porous metal film can be in filtered fluid
Disturbance under produce vibration, can reduce pollutant attachment thickness, possess self-cleaning function.Thus, it is possible to reach preferable filtering
Effect.The opening direction of the mesh of turbulent flow grid structure is vertical with membrane component surface liquid flow direction.
Further, it includes at least two membrane components, and the membrane component is hollow platy structure, adjacent membrane component
Entirety is linked as by turbulent flow grid structure.The runner of hollow platy structure is smaller, flow area reduce, it is necessary to wash away flow
It is corresponding to reduce.Accordingly, it is capable to be run under lower film surface eroding velocity, the flow output of pump is reduced, effect reduces operating cost.Phase
Turbulent flow grid structure is set between adjacent membrane component so that when liquid is by hollow platy structure in the present invention, due to membrane component
Between turbulent flow grid structure particular design so that flow area between membrane component is reduced, and it is further that liquid washes away flow
Reduce.
Further, the front and rear two sides of the hollow platy structure be porous metals diaphragm, one side be opening, opposite side
Face and top and bottom are sealing surface.So that liquid can only enter membrane component simultaneously by the porous metals diaphragm on front and rear two sides
Filtering, the liquid after filtering flow out from one side, which thereby enhance liquid filter efficiency.
Further, the turbulent flow grid structure includes being arranged at the grid on the outside of porous metals diaphragm and is arranged at lattice
Net the sealing surface of both sides.Thus under the effect of the pressure, the liquid entered by grid one end between membrane component passes through porous gold
Entered directly into after category membrane filtration inside membrane component, the liquid for not passing through porous metal film is arranged from the turbulent flow grid structure other end
Go out, improve liquid filter efficiency.
Further, the grid is cellular grid.Grid can realize above-mentioned flow area under this structure design
Reduce, wash away flow reduction, peel off the pollutant for being attached to film surface, reduce the thickness of pollutant attachment, possess automatically cleaning work(
Can and other effects.
Further, the hollow platy inside configuration is provided with circulation grid structure.Thus, when filtering a period of time
Afterwards, it is necessary to carry out backwash to membrane component inside, the backwash liquor being passed through in backwash process also can be in the effect of circulation grid structure
Lower turbulization vortex passes through porous metal film from inside to outside, is capable of the intimal surface of continuous erosion hollow platy structure, realizes
Effective cleaning to hollow platy structure.The opening direction of the mesh of circulation grid structure and membrane component surface liquid flow direction
Vertically.
Further, the porous metal film is stood by solid solution alloy, the metal simple-substance of face-centred cubic structure or body-centered
The thin slice that the metal simple-substance of square structure is made up of the metal polyporous material of matrix phase.Above-mentioned porous metal film possess with other
The lower characteristic such as filtration resistance, bigger filtration flux under the equal filtering accuracy of film.
Present invention also offers a kind of filter, including shell, the filtering film component that is arranged in shell, the shell bag
Stoste chamber, the net liquid chamber being connected with stoste chamber are included, the stoste chamber is provided with stoste outflow, stoste outlet, and the net liquid chamber is provided with
Net liquid import, net liquid outlet, the filtering film component is above-mentioned filtering film component, hollow harden structure one in the filtering film component
Side opening and the net liquid inlet communication, the net liquid chamber are additionally provided with backwash mouth.Filter in the present invention under the above constitution,
Liquid to be filtered first enters filter interior from stoste outflow, and liquid passes through the membrane filtration module in the present invention, porous metals
Film possess with lower filtration resistance, bigger filtration flux under the equal filtering accuracy of other films；Liquid passes through in the present invention
Membrane component when, due to the special mesh-structured design of turbulent flow grid structure, can be produced when liquid flows through turbulent flow grid strong
Turbulent flow whirlpool, continuous and effective can be formed to film surface and washed away, peel off the pollutant for being attached to film surface.Meanwhile porous metals
Film can produce vibration under the disturbance of filtered fluid, can reduce the thickness of pollutant attachment, possess self-cleaning function.Thus, it is possible to
Reach preferable filter effect, therefore improve the filter efficiency of filter in the present invention, improve the filter effect of filter.
After filtering for a long time, the film surface of membrane component, which still has pollutant attachment, influences filtration flux, it is therefore desirable to carries out backwash.Backwash
It is that cleaning liquid passes through porous metal film from circulation grid structure, by metallic film surface by being pressed into cleaning liquid to clear liquid chamber
Pollutant peel off.Backwash cleaning can be carried out to membrane component inside by being passed through cleaning solution body by backwash mouth.
Further, the stoste chamber is set with net liquid chamber for tiled configuration, and the stoste outflow is arranged at stoste bottom of chamber,
The stoste outlet is arranged at stoste chamber top, and the net liquid import is located at stoste chamber and net liquid chamber junction, the net liquid outlet
Net liquid chamber top is arranged at, the backwash mouth is arranged at net liquid bottom of chamber.Said structure causes filter effect and the cleaning of the present invention
Best results.
Further, inlet baffle is provided with the stoste outflow, outlet damper is provided with the stoste outlet.Thus may be used
To avoid membrane module from directly being impacted, while it can also play a part of evenly distributing liquid.
It can be seen that filtering film component of the present invention when in use compared to existing filtering film component under equal filtering accuracy it is more
Mesoporous metal film possess with lower filtration resistance, bigger filtration flux under the equal filtering accuracy of other films；Liquid passes through this
During membrane component in invention, due to the special mesh-structured design of turbulent flow grid structure, it can be produced when liquid flows through turbulent flow grid
Strong turbulent flow whirlpool, continuous and effective can be formed to film surface and washed away, peel off the pollutant for being attached to film surface.It is meanwhile more
