Description
Technical field
The utility model relates to solid-liquid separation technique fields, and in particular to a kind of flat-membrane element support component and flat membrane member
Part.
Background technique
Mixing-reaction-separation is the big GU Generic Unit operating technology in general industry field three, especially solid-liquor separation, public
Think the most common technological means of purifying products process.The Typical Representative of new and effective Technology in Solid/Liquid Separation includes micro-filtration and ultrafiltration
UF membrane is formed regardless of material, and the turbidity of filter liquor is general≤1.0NTU, far superior to gravitational settling, high speed centrifugation,
The industrial technologies such as plate compression, belt filters pressing, folded spiral shell machine, show extremely wide market application prospect.
More mature micro-filtration and ultrafiltration membrane includes plate membrane and the big mainstream pattern of hollow membrane two in the world at present, wherein putting down
The advantages such as plate membrane microfiltration and ultrafiltration have big flux, easy cleaning, the service life is long, O&M is simple, but there is also some inherent insufficient.Than
Such as, plate membrane effective filtration area is less than normal, loading density is relatively low, gas-water ratio is bigger than normal, and unit power consumption is higher etc., has seriously affected flat
The scale and industrialization of plate membrane technology and equipment are universal.Leading to the above-mentioned insufficient basic reason in inherence is that there is no light weight in the industry
Change, permeability is good, high mechanical strength support component is available.
The state of the art of inner support element is sincerely introduced so that sludge separates as an example below: as Chinese patent CN1676202,
CN101541406、CN201534787U、CN201493055U、CN201692771U、CN104107640A、CN102512963A、
CN106630130A、CN104307375A、CN104399373A、CN206843180U、CN206622002U、
Described in CN206308111U, CN206492403U, CN206751497U, CN206308112U etc., substantially using rotproofness it is good but
The low sheet plastic of rigidity, has longitudinal diversion channel slot (the alternate pattern that is staggered in common longitudinal direction) in its front and back sides, sticks plate membrane
Inner support element is inserted on the inside of frame limit fixation in wide U-type groove, and multiple flat-membrane element assembled parallels are at so-called " plate membrane
Component "；Plate film assembly is lifted into aerobic sludge pond or membrane cisterna bottom of pond, realizes solid-liquor separation function under gravity or pump driving
Can, draw high-quality water outlet.And mass production practical data shows:
(1) it is restricted by mechanical strength, commercially available inner support element is the thicker plastic plate of thickness, wherein the thickness of inlet member
For 7.0mm ~ 8.0mm, domestic element with a thickness of 5.5mm ~ 6.0mm, inner support element material cost accounts for finished product flat-membrane element
40% ~ 60%, the high serious Rapid Popularization application for hindering plate membrane microfiltration and ultrafiltration in sludge separation field of manufacturing cost；
And reduce support component thickness and will cause rigidity not enough, it is insufficient to allow it to erect support and keeps stablizing.
(2) it is required to be limited by fluidised form between adjacent flat-membrane element, when using commercially available inner support element, flat-membrane element
Installation interval is usually 6.0mm ~ 8.0mm, causes plate film assembly loading density extremely low, and gas-water ratio and unit power consumption occupy height not
Under, operating cost is higher, and seriously restricts the market share expansion of plate membrane microfiltration and hyperfiltration technique.
(3) it is designed and is inspired by import inner support component structure, commercially available domestic inner support element tow sides are equipped with boss
(the shallow formula of similar Japan's soup, longitudinal strip boss) or protrusion (similar Japan's Kubo field formula, diamond shape protrusion), are filtered as plate membrane
When work fulcrum or manufacture when solder contacts.But since these boss or protrusion integral area are larger, plate is significantly cut down
Effective area when film filters, so that the flux of plate membrane unit area is substantially reduced.
In view of the above-mentioned problems, Chinese patent CN102512963B discloses a kind of plate membrane inner support element, by film
Element support plate tow sides are each provided with several boss for spreading and being higher by support plate face, and the combination of adjacent panels film membrane component relies on
Support plate face boss prevents the deformation that warps, support component thickness is thinned by original 5.5mm ~ 6.0mm is as interval support
3.5mm or so, material cost saves 30% or so, but there are following technological deficiencies for this technical solution:
(1) aperture processing need to be carried out to the plate membrane on flat-membrane element, and plate membrane at boss is effectively sealed, it is no
Then easily cause water outlet or cleaning medical fluid because of the short stream that is open, and then plate membrane filtration functional fails.
(2) though U-shaped slot is not recycled to insert between support component, it need to be compressed and be sealed with fasteners such as bolts, side is close
Envelope must use sealing joint strip or side seal board to be sealed, and watertight problem can not eradicate in engineering practice.
(3) after a large amount of hair fibers are cared for or wound to the support plate face boss between adjacent flat-membrane element, plate membrane is effective
Filter area can be greatly decreased, it has to which maintenance of stopping transport is artificial to remove, and O&M difficulty dramatically increases.
Chinese patent CN104107640A then discloses a kind of improved flat-plate film inner support element, i.e. inner support element table
Boss is no longer arranged in face, but vertical strip boss is arranged in surrounding, and by opening up groove or flange on vertical strip boss,
Make the mating sealed around of adjacent support plate, U-shaped slot location and installation or need to be tight with bolt etc. need to be used by overcoming the prior art
Firmware compresses the problem of sealing, contracting installation work-hour and cost of manufacture, alleviates hair fiber winding in a way and side is close
Envelope problem, but still there are following shortcomings:
(1) the vertical strip boss of support plate surrounding setting prevents the rising between flat-membrane element to clean air-flow, inevitable
Cause plate membrane to block rapidly, can not run steadily in the long term.
(2) since the vertical strip boss of plastic material is higher by flat-membrane element 3.0mm ~ 6.0mm, mechanical strength is lower, easily
Fracture or deformation are caused, limit is caused to fail.
(3) it is limited by vertical strip boss height, the loading density of flat-membrane element is lower, plate film assembly higher cost.
(4) support plate front and back sides design has alternate longitudinal diversion trench, and setting direction is parallel with strip boss.It is cleaning
Air-flow turbulent fluctuation effect under, vertical flat-membrane element direction easily deforms, between initiation element fluidised form deteriorate, cause plate membrane block into
Journey quickening, flux sharp-decay, the chemical cleaning frequency increase suddenly or even overall performance is remarkably decreased.
