Description
Technical field
Utility model is to the improvement of water treatment with membrane support plate in the flat membrane component, and it is little to relate in particular to a kind of water resistance that filters out, and filtration flux is big, the diaphragm long service life; And thin thickness and not yielding, and the flat membrane component that can regulate the membrane component spacing is as required arbitrarily used gripper shoe.Also relate to the flat membrane component and the plate film assembly of gripper shoe formation thus.
Background technology
Flat membrane component is an important core element in the MBR membrane bioreactor; And membrane support plate is the important core parts of flat membrane component; The gripper shoe of support plate film such as Chinese patent CN1676202, CN101541406, CN201534787U, CN201493055U, CN201692771U etc. are said; The guiding gutter that drain measure or guiding soup clean vertically is provided with, and only on the top or the side, top a delivery port is set, promptly have only single delivery port structure of a upper water-out mouth.And flat membrane component is bigger usually for adapting to the big flow dimensions of processing, and is vertical high rectangle, and for example commonly used is high by 1.8 * wide 0.5 meter big plane.Filter the single alternate vertical diversion groove of effluent adopting and be guided to the top water outlet; For the membrane component of (large tracts of land even higher) about up to 1.8 meters, vertically each point pressure is objectively different to be immersed in the water plate face, and transmembrane pressure difference is big up and down; For being guided to upper water through the face water outlet, the membrane component bottom chews discharge; Operation must be adopted the pump suction, can not adopt the operation of gravity pressure reduction basically, and this is a factor that causes operation energy consumption high.Even and adopt the suction draining, owing to differential water pressures does not wait reason, face each point suction force up and down is objective evenly impossible; And also have the dead angle to exist, the each point suction force is inhomogeneous up and down for upright plane, very easily causes the film surface pollution degree varies; For example near the big zone of delivery port suction force, film surface pollution is serious, and is light relatively away from suction delivery port film surface pollution; Long-play makes that each regional resistance of face is inhomogeneous, also can shorten diaphragm service life.During the online Chemical cleaning of single delivery port, because of residual filtered water in the gripper shoe lower guide chute, clean chemical agent get into membrane component can be diluted when inner; Cause actual cleaning soup inhomogeneous in the face CONCENTRATION DISTRIBUTION, sometimes even can not arrive all faces, cause online Chemical cleaning not thoroughly, not comprehensive; Not only influence cleaning performance; And clean thoroughly the zone for a long time repeatedly and pollute infiltration and can not clean at last, make the film contamination resistance descend, treatment yielding water also descends; Besides, exist in the membrane component and filter surplus water, top perfusion solution infiltration bottom face consumption is big, causes the cleaning liquid waste, has increased film on-line cleaning expense.
Chinese patent CN101905922A, the disclosed back-washable flat membrane component of CN101829504A respectively are provided with a delivery port at two ends up and down, form two ends water outlet up and down and advance the soup on-line cleaning, and between the two outlet on top and bottom mouth, be provided with valve.Though can reduce half the vertically water outlet flow process in theory, reduce water resistance with this, objectively vertically there is resistance difference in face; The two ends water outlet up and down of single alternate vertical guiding gutter still can not be eliminated longitudinal resistance difference, adds membrane component upper and lower side pressure difference in water; And can change because of film stops up, actual will formation aspirated water outlet up and down simultaneously, and the control difficulty is very big; So adopt valve that two outlet on top and bottom is switched, like this running still be again single-ended into and out of.The above-mentioned deficiency of prior art is not still overcome.
Chinese patent CN101857302A submerged flat membrane element; The intermediate support plate upper and lower end respectively is provided with two suction tubes respectively; And some up and down alternate hyphens are set to the groove that catchments (laterally not full-mesh) between adjacent vertical guiding gutter, solve more large tracts of land membrane component (for example the highest 2.5 meters).Chinese patent CN102070246A immersion flat membrane component; Improvement is arranged to two sections of upper and lowers with gripper shoe; Put in order plate middle the be made up of for " H " type installation connection strap cross section; Upper and lower end respectively is provided with two suction tubes, forms two up and down separate membrane filtration systems, and the horizontal weak point groove (laterally not full-mesh) that catchments is set between the several adjacent guiding gutter of upper and lower support plate.More large tracts of land (height 4-4.5 rice) is made in solution.Though between the alternate vertical guiding gutter of gripper shoe, be provided with some alternate up and down horizontal short grooves that catchment that are communicated with; Still need to discharge but catchment by cannelure; The water outlet long flow path, pressure reduction shortcoming big and single alternate vertical guiding gutter still exists up and down, is still overcome.And the latter still is two independent film elements up and down.
Chinese patent CN201722204U and CN201722200U membrane bioreactor flat membrane element, gripper shoe two sides adopt the circular projection that evenly distributes to form the space as seeing through the liquid passage.It is opposite that the alternate longitudinal groove of itself and prior art forms guiding gutter, changes into by close Distribution Center dome support membrane, between the dome of close Distribution Center, forms the flow-guiding channel that communicates in length and breadth, and what goal of the invention solved is that face is cleaned evenly, improves contamination resistance.This though communicate in length and breadth, can evenly and reduce flow passage resistance force of waterproof, and make the panel exhalant canal not have the dead angle through the flow-guiding channel that diffusing some cylinder support membrane of intensive protrusion forms, and reaches the raising cleaning performance.But bring other shortcomings: this support structure plate for example; Same thickness intensity and rigidity will reduce (actual attenuate plate face keep vertical thickness) significantly; More being easy to generate distortion in the use warps; If adopt, cause cost to increase again, and the unit volume effective filtration area reduce than slab face gripper shoe; Lean on dome to support face, must cause the dome dense arrangement, not only increased difficulty, realize for the large tracts of land gripper shoe is more difficult to the die sinking manufacturing; And the thin micropore face (having only 0.2mm usually) of small size convex cylindrical support, null circle and face contact-making surface are little, under the hydraulic pressure effect, cause the damage of microporous barrier easily.
Secondly, the face gripper shoe adopts the good but sheet plastic of rigidity relative mistake of rotproofness basically, and the assembling of adjacent membranes element is inserted width both sides alternate U type slot on the frame support through vertical, and promptly the alternate location of film is to lean on the gripper shoe dual-side to insert U type groove to locate.Flat membrane component is since invention, and adjacent spaces all is so, other forms never again, and assembling mode is also unique to be the downward plug-in type in top.For being inserted water pressure in effectively preventing to use and below aeration scouring force effect is out of shape, guarantee that the vertical plate face is straight, the plastic support plate thickness is usually at least at 5.5-6.0mm, and area increases the proportional increase of thickness.There is following deficiency in actual use in this gripper shoe: the one, and relative thicker gripper shoe (5.5-6.0mm); Become membrane component and constitute the second largest factor of cost; Its cost accounts for the 40-50% of full wafer membrane component; Also be to cause the reason that can not ignore that the membrane component cost is higher, promote difficulty, can cause rigidity not enough again but reduce plate thickness, not enough so that the setting gripper shoe keeps the plane; The 2nd, big planar film element is to lean on side location (inserting U type groove) to keep element to require spacing (being generally 7-8mm); For big plane like this, even so thick plastic support board only depends on width dual-side location; Unavoidably can deform in actual use and warp; Distortion warps and causes that spacing changes at the position that warps between adjacent two membrane components, and particularly can to cause between membrane component air water to wash away inhomogeneous for pitch smaller, produces deposition; And then cause face to stop up, make effluent flux descend.Though can overcome the distortion shortcoming that warps through increasing gripper shoe thickness in theory, to constitute cost higher because it accounts for, and it is more that buildup thickness can cause cost to increase, and more influences applying of membrane bioreactor; Secondly, gripper shoe thickness increases, and also will reduce effective filtration area (minimizing of same components thickness sheet number) in the unit volume, and weight increases.Gripper shoe is in use yielding to warp though therefore have now, and comprehensively each factor practical application thickness is still in the majority with 5.5-6.0mm.It is high that flat membrane component supports the thickness of slab cost, and still yielding warping in using, and become the immersion plate film assembly and used the obstacle that is difficult to go beyond.
Besides, prior art multi-disc membrane component is assembled into membrane module, is employed in the support width both sides and is provided with or processes alternate U type groove, membrane component is inserted from top to bottom be assembled into membrane module (the perpendicular formula of inserting is installed) in the U type groove.This kind structure and assembling mode; Mainly contain two big deficiencies: the one, framework U separation is set; The membrane component spacing is just confirmed and can not be changed, and is difficult to adapt to different and the requirement of variable sewage optimal arrangement spacing, if change the membrane component spacing; Must make assembly again and use framework, the component framework versatility is poor; The 2nd, to insert downwards on the assembled on site and install, the operation of need climbing is very much inconvenient, for up to 1.8 meters or higher membrane component, the perpendicular formula of inserting is installed extremely inconvenient.
Above-mentioned deficiency still has is worth improved place.

Before detailed description, earlier do an introduction, so that those skilled in the art have one clearly to understand to this patent general plotting technical scheme and the basic fundamental effect that reaches through the basic function and the effect that can reach to invention.
Utility model is because in former dull and stereotyped membrane component gripper shoe; The vertical zone line in two sides increases by at least one horizontal transverse channels to the vertical guiding gutter of width outermost; And delivery port; Form go up at least in (differ and be decided to be 1/2 center) following 3 or with upper water-out, thereby flat sheet membrane is divided into two roughly approaching or above filtering surface of suction force up and down on filtering surface, soup cleans and two ends water outlet up and down for the existing single-ended water outlet in top/advance/advance the soup cleaning; Not only reduced the water conservancy diversion flow process; Big height filtering surface transmembrane pressure is obtained evenly, and the guiding gutter intersection communicates in length and breadth, can make water outlet by the minimum discharge of resistance (the backwash soup is uniformly distributed with by the resistance minimum equally).Can also filter surplus liquid through bottom delivery port discharge section before the line cleaning injection soup again, make that not only cleaning soup entering film bottom speed is fast, reduce soup consumption, and the minimizing of filtration water, ooze to whole face liquor strengths even.And the some boss that exceed the gripper shoe face of tow sides distributed and arranged, thereby make assembling film assembly membrane component adjacent spaces, not to rely on the large tracts of land side to insert framework U type groove location; But be combined to form adjacent spaces by the some boss that exceed the gripper shoe face of gripper shoe face distribution; The plate face point that looses is combined to form at interval, even gripper shoe attenuate does not so warp owing to the plate face also can not be out of shape by multi-point support yet; Can the attenuate gripper shoe thereby solved, and don't can in use be out of shape and warp.In addition, the gripper shoe two sides respectively exceeds the boss of gripper shoe face, confirms height by 1/2 of two involutory minimum spacings; When making assembling adjacent membranes element; Can change adjacent spacing through on boss face, increasing pad, make it more than the minimum interval, to realize that spacing width is variable, thereby when making the assembling film assembly; Two membrane component spacings can be adjusted according to actual needs flexibly, and framework need be do not changed.Membrane module assembling positioned at intervals is supported by the some distribution boss of gripper shoe face, makes assembly assemble and framework apart, and can realize the components side dress.
Among the present invention.
The vertical zone line in gripper shoe two sides increases by at least one horizontal transverse channels to the vertical guiding gutter of width outermost; And the delivery port that connects transverse channels; Main effect is to make big height membrane component; Be separated into transmembrane pressure uniform two or polylith, be beneficial to reduce water conservancy diversion liquid in-out resistance.It is different to press the component film element heights, can design one or more transverse channels, considers that membrane component floods in the water pressure reduction difference up and down, and a kind of better is that transverse channels is arranged on gripper shoe to push up downward 40-75% interval.
The boss of the high out-of-plane of gripper shoe face; Be mainly used in adjacent shore plates (membrane component) positioned at intervals; And compress the component film assembly; Its some abundance of loosing is looked gripper shoe face size and decide, only need limited several or tens get final product, water conservancy diversion is still by vertical guiding gutter on the gripper shoe face (being different from Chinese patent CN201722204 support face cylinder).Boss is a kind of to be preferably the setting of positive and negative coordination; The boss height confirms that by 1/2 of adjacent involutory spacing wherein a kind of better boss height confirms that by 1/2 of adjacent involutory minimum spacing can pass through like this increases shim form in boss face; Increase the alternate spacing of adjacent membranes element, realize that spacing is adjustable.In addition, a kind of better is that all or part of protrusion boss of gripper shoe face thickness direction has through hole, and more convenient element is assembled into assembly, can in the thickness through hole, pass bearing pin when membrane component is assembled into membrane module and be fixed.
In addition; A kind of better is to make guiding gutter crosspoint positive and negative perforation in length and breadth; Seeing through diaphragm drainage or backwash soup like this can more help each interval transmembrane pressure of uniform planar by the derivation/importing of resistance minimal path, improves membrane flux; And also more uniform films pollutes, and also helps prolonging film service life.
For the gripper shoe that high ejecting plate face boss is arranged, when the component film element, a kind of better is to make microporous barrier in the lug boss position perforate, and film perforate periphery is bonded and sealed with gripper shoe.Can reduce to damage because of the boss teleblem causes the lug boss position face; And be same as prior art film periphery and gripper shoe sealing, and mainly be to form between film and gripper shoe to seal, guarantee the filtration of film; Avoid handling water or clean soup, make film ineffective because of the short stream of opening.Be bonded and sealed and can adopt prior art film and gripper shoe periphery sealing means, for example ultrasonic heat melts welding or glue bonding, and this belongs to prior art.
Membrane component, a kind of better is to adopt some to be combined into one, for example the 2-5 sheet; The compounded plate number is looked the gripper shoe size and is decided, if the excessive compounded plate number that should reduce of plate face, would to reduce the combined films element weight; Making like this that intensity reduces to obtain replenishing behind the gripper shoe attenuate strengthens convenient transportation and assembling.Some combinations, a kind of better is to seal with side slat in the adjacent sheet side, and its function is run out of from both sides when preventing aeration with assembling membrane module side-closed, and short stream can not arrive the top face.Can certainly not establish the side seal bar, after being assembled into assembly, install side seal board additional, have said function in two sides.
In this patent except that relating to above-mentioned said improvement part; All the other do not relate to part and existing flat sheet membrane gripper shoe, flat membrane component, and plate film assembly is identical, and for example vertically the guiding gutter positive and negative is crisscross arranged; And vertically there are the transverse channels of perforation and Shui Zui in the lower end; During the component film assembly, spacer bar or side plate sealing are adopted in adjacent membranes elements on either side or assembly side, prevent the short stream of aeration.
The utility model flat membrane component is used gripper shoe; With respect to prior art, owing to set up at least one laterally to the transverse channels of the vertical guiding gutter of width outermost at the gripper shoe positive and negative, guiding gutter is crisscross; And the positive and negative perforation of runner cross joint in length and breadth; The feasible guiding gutter that catchments is more unimpeded, and water outlet can be derived by minimum drag, has both reduced system's transmembrane pressure; Feasible filtration can be adopted gravity pressure reduction water outlet (only needing water level pressure reduction 2-3 rice to get final product), thereby can reduce system's operation energy consumption by a relatively large margin; In addition, can also make that the online Chemical cleaning of membrane component is more unimpeded, clean more thoroughly effectively, fully recover membrane flux, contamination resistance strengthens, and can also practice thrift the cleaning agent amount, shortens scavenging period, and prolongs diaphragm service life.Some boss on distribution protruding plate plane are as support at interval on the gripper shoe face, and a plurality of strong points support on the plane, changed original membrane component and relied on width dual-side location; Need with thicker gripper shoe (thickness is holded up rigidity for keeping, minimizing be out of shape require) and be prone to cause gripper shoe warp distortion, obviously attenuate gripper shoe thickness; Thickness can be by original 5.5-6.0mm; Attenuate is about 3.5mm, thereby makes supporting plate material weight reduce about 30%, and cost also can reduce about 30%; In addition, freight and lifting cost usefulness have also been saved in weight saving.Form at interval owing to adopt boss to support, the gripper shoe reduced thickness also can not cause the gripper shoe distortion that warps, and can guarantee that each dot spacing of adjacent membranes element interplanar immobilizes; Guarantee that air water washes away runner size unanimity, scouring intensity is even, can not cause because of the distortion that warps causes local pitch smaller and cause mud to pile up; Both can reduce the film pollution level, and can promote the membrane filtration effluent flux again, the limited boss of some distributions; The gripper shoe processing and fabricating is simple, does not increase former gripper shoe manufacture difficulty basically.In addition, the boss that forms spacing is set on the gripper shoe plane, has also changed membrane component assembled components method; Do not need to adopt again inserted mode installation up and down, can change and laterally install, not only greatly facilitate the assembled on site of membrane module by the side; And simplified the membrane support structure, and the U type groove of setting spacing no longer need be set, make framework separate with the membrane component positioned at intervals; Only use, thereby improved the versatility of component framework, also reduced the cost of manufacture of membrane support as component framework; And reduced installation labour (not needing to insert installation downwards) in a high position, for the MBR reactor reduces cost, the convenient installation made significant contribution.Besides, the boss protrusion height is confirmed the also favourable membrane component adjacent spaces that changes according to actual needs by 1/2 of involutory minimum spacing; Thereby can realize that the membrane component spacing is adjustable; Promptly washing away the size of runner can adjust, and makes under identical aeration intensity, can be directed against different sewage sludge concentration and viscosity; Adjustment improves the film contamination resistance to the scouring intensity of face.The vertical zone line of gripper shoe of the present invention increases by at least one horizontal transverse channels and Shui Zui to the vertical guiding gutter of width outermost; And adjacent membranes element spacing location relies on the plate face to loose the some boss by bumping the location; Membrane component is installed the side dress mode that adopts; Some membrane components are combined into the combined films element, and these have constituted this patent gripper shoe and membrane bioreactor is different from the prior art difference.
Below in conjunction with some optimization specific embodiments; Utility model essence is further understood in exemplary illustration and help; But the embodiment detail only is in order utility model to be described, not to be represented utility model design whole technical schemes down, therefore should not be construed as the total technical scheme of utility model to be limited; Some are In the view of the technical staff; The unsubstantiality that does not depart from utility model design increases and/or changes, and simple the change or replacement of technical characterictic to have same or similar technique effect for example all truely used novel protected scope.
