Description
Technical field:
The present invention proposes a kind of novel membrane separator, especially a kind of rotating centrifugal hypergravity membrane separator that places the rotating centrifugal hypergravity field to carry out the film separation process.
Background technology:
Membrane separation technique is that a kind of efficient, new and high technology of energy-saving and environmental protection, this technology have been widely used in fields such as chemical industry, food, pharmacy environmental protection at present; But because concentration polarization; Film pollutes, the unit are flux of film hangs down in the membrane process that causes; Operating cost is high, and reasons such as equipment investment height have greatly limited Application of membrane, and high-gravity technology is the application technology of a kind of can greatly reinforcement the " three pass " " one is anti-" effect; More and more receive scientific and technical personnel's attention and research and development, obtained successful Application at aspects such as environmental protection, chemical industry, nano material manufacturings at present.
The hypergravity membrane separation technique; Be to utilize rotating centrifugal to produce super gravity field, membrane module is placed super gravity field, the film separation process is accomplished under the hypergravity condition; Because the film separation process is undertaken by traditional gravitational field, become tens of times of fields to tens thousand of times of acceleration of gravity (g=9.8m/s
2) super gravity field under carry out, significant variations has taken place in its film separation process, has produced following effect:
1, effectively reducing film pollutes and concentration polarization
In the film separation process; The film surface produces the concentration polarization layer; The concentration of concentration polarization layer is far above the concentration of main body feed liquid, and the density of counting concentration polarization layer under the situation extremely greatly can not be higher or lower than the density of main body feed liquid because concentration does not coexist, in powerful centrifugal field, produce along direction or its reciprocal moving; Thereby leave the film surface, and then reduce concentration polarization and film pollution.
2, can improve the penetrating amount of elementary membrane area
When the flow pass cross-sectional area is very little after seeing through liquid film, a large amount of liquid that sees through is discharged, must impose pressure behind the bigger film it; Because pressure behind the bigger film has reduced transmembrane pressure greatly, so penetrating two Conferences of unit are film reduces; This phenomenon is at the bigger external pressure hollow-fibre membrane of length; What show in the capillary-pipe film is very serious, and the hypergravity film separates and can overcome the above problems, and is example with the hollow-fibre membrane; When the length of doughnut film along centrifugal field or approximate when the centrifugal field direction distributes; Seeing through liquid can throw away at action of centrifugal force lower edge film pipe, so and in this process because behind the film that Ge Shi produces minimum and transmembrane pressure effect film that only the minimum part film back side is produced of pressure can not produce big variation, so film can keep higher penetrating amount.
3, can obtain the higher trapped substance of concentration
Film concentrates and the process characteristic of centrifugal sedimentation because hypergravity membrane separator has concurrently, so under the identical condition of feed pressure, its trapped substance concentration is higher than traditional film and concentrates.
The hypergravity membrane separation technique is a novel application technology; At present; Research and the achievement of using and seldom in known consulting reference materials; Only there are " rotating bed super gravity field device " (number of patent application 03115674.6) and " centrifugal rotation hypergravity-membrane separation technique " (number of patent application 03100089.4) two patents to deliver with tubular structure; These two patents have proposed the technical scheme that film separates under the hypergravity condition, but all exist some problems to cause feasibility poor, fix like " the rotating bed super gravity field device with tubular structure " emphasical tubular membrane or hollow-fibre membrane two ends; Radially arrange; In fact the hollow-fibre membrane that exists owing to coriolis force can't keep radially arranging in the separation process of hypergravity film, very easily breaks because the liquid flow impact hollow-fibre membrane that produces is shut down in coriolis force input and output material and start, causes membrane module to scrap." centrifugal rotation hypergravity-membrane separation technique " is characterized in that film faces towards surface rotary drum axle center, and it is more serious that concentration polarization and film are polluted, and in addition, these two patents do not propose feasible solution to cleaning, the input and output material of film yet." a kind of membrane module of under the hypergravity condition, working " (number of patent application 2008201417002) proposed a kind of dependence rotary drum and supported; The new membrane module that film one end is fixing; Solved the problem of above two patents preferably; This patent has also proposed trapped fluid, has seen through liquid, the discharge of light liquid bubble and the solution that feeds of material liquid; But only be to the discharge of membrane module and feed that this patent does not have yet and can and see through liquid and the energy recycling of trapped fluid provides solution to the generation of super gravity field.

The operation principle and the implementation method of this machine are described below in conjunction with the real work situation:
Axle power by generations such as motor or hydraulic motor internal combustion engines rotates main shaft 6 through drive disk assembly 19; Main shaft 6 rotates rotary drum 30 through key 29; And make membrane module 1, material liquid in the rotary drum 30, see through liquid, trapped fluid, bubble light liquid, backwash just washing material and all placing overweight centrifugal field, thereby realizing the film separation process under the hypergravity condition.
Material liquid is through the inlet of the material liquid on material liquid, the bubble light liquid distributor 38 41; Get into feeding liquid and flow out pivotable sleeve 31 inner chambers; Material liquid flows out pivotable sleeve 31, on have a lot, along relief hole 34 in relief hole 32 in the bottom that its cylinder bus Cheng Liezhuan distributes and the top; And two kinds of holes do not list same up and down; The bottom of material liquid bubble light liquid distributor 38 also for have outside the bottom relief hole 33 and the outer relief hole 35 in top and with corresponding up and down in relief hole corresponding one by one, relief hole is communicated with when last relief hole or inside and outside down during the relief hole alignment, material liquid just can get into rotary drum 30 interior membrane modules 1 and contact with film is surperficial; And, realize that film separates by the feeding liquid pressure of material liquid feed pressure and centrifugal generation.Because relief hole does not list same up and down; And its row axis is apart more than or equal to following relief hole aperture; So relief hole can not inside and outside alignment of while be communicated with up and down, just material liquid can not be simultaneously through relief hole discharge under the mountain, so when rotating shaft 40 drive feeding liquids flow out pivotable sleeve 31 rotations; Just can realize charging and following charging respectively, the mode of charging helps the eliminating of bubble light liquid about adopting.
Material liquid in the membrane module 1 is separated into trapped fluid through film and imports the trapped fluid annular collecting tray 48 that has on the rotary drum bottom 7; And under material liquid pressure and action of centrifugal force, flow into trapped fluid side groove 49; Because trapped fluid side groove 49 is that side direction is outwards left; So can make trapped fluid in trapped fluid annular collecting tray 48, produce flowing along cannelure; Thereby guarantee that trapped fluid more balancedly flows out in membrane module 1; Also can lower the deposition of trapped fluid in trapped fluid annular collecting tray 48, get into the cavity of main shafts 6 inner hole walls and positive backwash material conduit 24 outer walls formation through the trapped fluid entering of trapped fluid side groove 49 and through the trapped fluid passing away 15 that rotary drum bottom 7 is provided with, trapped fluid outlet 23 discharges that on positive backwash material trapped fluid distributor 20, have.
The liquid that sees through from membrane module 1 discharge; From see through liquid rotary drum in the passing away 44 of membrane module 1, get into and see through pendular ring shape collecting tray 47, and see through liquid passing away 27 through getting into through liquid side groove 50 with the formation of rotary drum 30 inwalls; Put through liquid ejector 28 from the liquid entering limit that sees through that sees through 27 discharges of liquid mouth passing away; And from be bumped into wherein see through wear-resisting nozzle 51 ejections of liquid since see through the liquid ejiction opening to the distance of rotary drum 30 turning cylinder center lines greater than seeing through the distance that pendular ring shape collecting tray 47 arrives rotary drum 30 center of rotation, must see through hydraulic coupling so under action of centrifugal force, can produce; Under its effect, make through fluid power must speed spraying along the rightabout that rotary drum 30 rotates; And will pass to rotary drum 30. through the entrained energy of liquid and see through liquid and when seeing through wear-resisting nozzle 51 ejections of liquid, can the air that get into toroidal cavities 52 through air admission hole 53 through suction hole 54, be sucked and see through wear-resisting nozzle 51 internal controls of liquid; And with see through liquid and mix; Form great amount of bubbles seeing through liquid ejection back, thereby realize that to a certain extent the foam that sees through liquid separates, this process is very valuable when this machine is used for municipal wastewater and deviates from anionic detergent.
When film separation and gas back-flushing; Having light liquid and a large amount of gas bubbles produces; Bubble and light liquid can be concentrated to rotary drum 30 central upper under the buoyancy function of centrifugal force and earth gravitational field generation; Through light liquid bubble passing away 43, discharge from the light liquid bubble outlet of opening on material liquid light liquid bubble distributor 38 42.
This machine can be realized the online gas back-flushing of not stall of rotary drum, and concrete operation principle and implementation method are that Compressed Gas is from positive backwash material inlet 22; Get into backwash material distribution cavity 45 and see through passing away 44 in the liquid rotary drum through positive backwash material trapped fluid distributor 20, positive backwash material conduit 24, backwash material communicating pipe 3 and backwash material case passage 46, get into film and see through side, the reverse film that sees through under the effect of its pressure; Thereby realize the back flush of film gas, through seeing through liquid passing away 27, put from the limit through liquid displacer 28 and discharge for preventing compressed air; The trend that sees through liquid passing away 27 has adopted following mode, sees through liquid passing away 27 and at first crosses through turning back behind pendular ring shape collecting tray 47 certain distances away from the catadioptric then intersection of rotary drum axle center to rotary drum feather edge, and the edge at the bottom of the rotary drum and put through liquid ejector 28 inner chambers with the limit links to each other; Its operation principle and implementation method are below described; See through side and reverse when seeing through film when backwash gas gets into film, see through output of fluid and reduce or stop, under the effect of centrifugal force and compression pressure; See through liquid see through liquid passing away 27 near main shaft turn back a little before still be continuous fluid; And form the liquid sealing, and, this then is discontinuous shape or no liquid after turning back a little, this moment, air just got into the later passage of this kick-point; This pressure and atmospheric pressure of turning back a little is close; And at the continuous fluid before this kick-point under action of centrifugal force, can produce must pressure, thereby stoped the discharge of Compressed Gas.
The gravity of rotary drum 30 through main shaft bearing 26 inner rings on the main shaft 6, go up support set 9, pass to permanent magnet 10; Last permanent magnet 10 relies on the repulsion of magnetic pole that rotary drum gravity is passed to down permanent magnet 11 at a distance from sky with following permanent magnet 11 like poles relatively; And through support set 12, lower main axis bearing 25 race bearing friction tops 18 are passed to support 13 down; This structure can effectively reduce shaft strength, reduces the bearing friction power attenuation.
With Fig. 3, Fig. 4, Fig. 5, Fig. 6 be basic description do not do that back flush only does gas-liquid forward flushing make structure and operation principle, the implementation method of the hypergravity membrane separator of rotary drum driving force with motor hydraulic motor internal combustion engine.
Only its difference is described below the structure of this machine and aforesaid hypergravity membrane separator, operation principle etc. are basic identical;, membrane module 1 can not adopt the gas liquid back flush when selecting anti-seepage membrane or NF membrane for use, so, should adopt following design; Remove used element of gas backwash and structure; Clean and increase the gas liquid forward, because anti-seepage membrane, the permeable amount of NF membrane are less, it is less to see through the contained energy of liquid; So this machine can adopt Fig. 1, the liquid that sees through shown in Figure 2 to discharge mode, also can adopt Fig. 3, Fig. 4, discharge mode shown in Figure 6.
Forward cleaning material cover 55 is equipped with in the upper end of rotary drum bottom 7, and rotary drum bottom 7 is provided with forward cleaning material passage 57, forward cleaning material passage 57; Start from rotary drum bottom 7 upper ends and end at trapped fluid annular collecting tray 48; When carrying out the forward flushing, cleaning material is from the positive backwash material conduit 24 of positive backwash material inlet 22 warps, forward cleaning material passage 57; Trapped fluid collecting tray 48; Get into membrane module 1 and just clean by touching realization with the film surface, the forward cleaning material can be that Compressed Gas also can be the clear water cleaning fluid.
The lower surface of rotary drum bottom 7 is equipped with the end and is put through liquid displacer 56; Which is provided with and see through liquid outlet 58; The direction of rotation of its opening direction and rotary drum 30; And through the end put through liquid displacer 56 inner ducts with see through liquid passing away 27 and communicate; Through seeing through liquid passing away 27 see through liquid put the end of through through liquid displacer 56 from it see through 58 ejections of liquid outlet owing to see through the direction ejection of liquid court and rotary drum 30 direction of rotation, so thereby can the part energy that it is entrained pass to rotary drum and realize and must recycle by energy.
In the film separation process; The big phenomenon of the big flow of trapped fluid discharge pressure usually can take place; Like desalinization, at this moment trapped fluid can carry very big energy, will increase the operating cost of membrane process as not being used; The structural representation of the hypergravity membrane separator when rotary drum driving force that shown in Figure 7 is is the fluid dynamic of feeding liquid, trapped fluid; The center upper portion of rotary drum 30 is equipped with material liquid rotary drum driver 60, and trapped fluid rotary drum driver 62 is equipped with in the bottom, and rotary drum central authorities have material liquid to get into rotary drum hole 61.
When high pressure feedstock liquid when material liquid driver feed liquid inlet 59 gets into material liquid rotary drum drivers 60; Part material liquid energy rotates rotary drum 30 through material liquid rotary drum driver 60; Material liquid through material liquid rotary drum driver 60 gets into rotary drum hole 61 through material liquid; Get into that rotary drum 30 is inner to carry out film with membrane module 1 and separates the material liquid that passes through the film separation and become trapped fluid; Get into trapped fluid rotary drum driver 62 through trapped fluid passing away 15, and the energy that it is entrained is passed to rotary drum 30 back outflow rotary drums 30.When rotary drum 30 starts or rotating speed when being lower than certain value; Feeding liquid rotary drum driver 60 can improve the rotating speed of rotary drum 30; But when rotary drum 30 rotating speeds were higher than certain value, material liquid rotary drum driver 60 can improve the feed pressure of material liquid; Material liquid rotary drum driver 60 and trapped fluid rotary drum driver 62 can be that spiral hinge cage, screw rod, turbine also can be propeller blades.
Comprehensive above analyze the present invention and solved in the separation process of hypergravity film, the generation of unavoidable super gravity field, the sending to of the material liquid during film separates through rational design; Trapped fluid; See through the discharge of liquid, light liquid and bubble, and the practical problems such as energy recovery and utilization that see through liquid and trapped fluid, and (reverse osmosis, nanofiltration are dense film to reverse osmosis, nanofiltration and ultrafiltration and two types of heterogeneitys of micro-filtration; Can not back flush; Ultrafiltration micro-filtration is a perforated membrane, can back flush) propose two kinds of different films and cleaned solutions, so this patent is the hypergravity membrane separator that is suitable for multiple membrane process process with feasibility.
