One kind in material is shaped.
Specifically, the profile of the hollow ceramic flat membranes element is flat structure, the length direction inside it
The through hole at multiple straight-through two ends is provided with side by side.
The present invention compared with prior art, with following beneficial effect：
(1) advanced technology, structure is novel.Ceramic hollow Flat Membrane has good anufacturability, bigger filter water
Flux, less filtration resistance is more convenient reliable anti-cleaning performance, favored by users, big substituted tubular membrane
The gesture of element.The present invention is directed to ceramic membrane some problems present in its application process, from the combination of single membrane component
Structure, the membrane module arrangement of filter element, the combination of filter element, the anti-cleaning way of filter element etc. is multi-party
Face, it is proposed that new design philosophy, so that, make the more than technological precedence of flat board membrane filtration system, and structure is more novel.
(2) it is simple in construction, it is easy to install.Filter uses submerged structure, is directly installed in former pond, no
Water pipe and blow-off pipe need to separately be tapped into.Collecting chamber is the space of a relative closure, is supported on by support in raw water, and support is one
Tower structure, surrounding is to open wide or semi-enclosed.The fixing end of membrane module is that in collecting chamber, contact is water purification, not by
The pollution of raw water, opening top inspection door can just mount and dismount.
(3) filtration resistance is small, and operating cost is low.Flat Membrane is for tubular membrane, because the flow of filtering is shorter, resistance
Lack 30% or so.Using the arrangement and frame mode of the present invention, the pure water inlet of each membrane module directly with collecting chamber insertion,
Centre is not required to connecting pipe, just accesses house steward by pure water pipe, and its resistance is also seldom.Filter is directly submerged in raw water,
Film surface is uniform with dirt touch opportunity in water, and filtration resistance is lower.
(4) disposal ability can be lacked greatly, supporting flexible.Several filter elements are single-row or multiple row is combined, and can set up into
Quite huge filtration system, is adapted to the larger occasion for the treatment of capacity.Single filter can be with independent operating, and passes through reduction
The quantity of membrane module or the appearance and size of membrane component, are adapted to the less occasion of various treating capacities.It is used for for industrial and mining enterprises
The purified treatment of all kinds of waste water, it can also be used to the purified treatment of urban water supply.
(5) the filter capacity favorable regeneration effect of membrane component.Using the technology of the present invention, the compressed air or pressure of reverse cleaning
Power water, by collecting chamber stepless action in each membrane module, so that, cleaning performance is more preferably.In the bottom of each filter, set
Gas explosion device, gas explosion effect directly acts on the outer surface of film, the mud cake and debris on surface is come off.
(6) mechanical strength of membrane module is big, is hardly damaged.It is well known that the machinery of the disadvantage of inorganic ceramic membrane is strong
Degree is poor, it is impossible to which withstand shocks power, is still more the hollow Flat Membrane that thickness is 3-6mm.Assembled by existing structure mode, one
The fixed installation of piece piece, the rigidity of membrane component is not enough, and swing can be produced under powerful anti-cleaning pressure and causes to damage phenomenon.
The present invention uses the connector of upper, middle and lower three, multiple membrane components is connected in series in its length direction, in thickness direction side by side
Three connectors, then, are fixed into an entirety, the rigidity of single membrane module increases by connection by stainless steel trough plate
By force, the damage caused by external force during transportation, installation and use is prevented.
(7) cost performance is high.Tubular ceramic membrane is replaced using the ceramic membrane of the boundling combination die blocking structure of the present invention
And ordinary flat ceramic membrane is as filter element, and it is more reasonable in the installation of membrane component, more simply, so that overall price
On it is more excellent.Using submerged structure, the supporting structure for installing membrane module is simpler, and manufacturing cost is lower.
