Description

Modular filtration system

Invention field

The present invention relates in general to the filtration of the filtration of fluid, particularly water.

Background of invention

Although through for many years a lot of progress being arranged aspect the water purification, but still continue the needs that exist water to purify.A lot of places in the world all lack the fresh water of drinking and irrigating, and have the place of a large amount of fresh water at other, and water is often polluted by chemistry and biological pollutant, metal ion and analog.People also need filtering economically such as other liquid such as industrial chemical and food fruit juice.The 4th, 759, No. 850 United States Patent (USP) has been discussed a kind of reverse osmosis of removing alcohol from the hydrocarbon that has unnecessary ether, and the 4th, 959, No. 237 United States Patent (USP) has been discussed the reverse osmosis that is used for orange juice.

These need all by filter, particularly reverse osmosis is satisfied, and in described reverse osmosis, adopts pellicle under certain pressure each constituent to be separated.Here said term film refers to a kind of function filter, and it can comprise one or more semi-permeable layer and one or more supporting layer.According to the film quality that adopted, hyperfiltration such as can remove from the macro molecules to the microcosmic particle at particles with different sizes, and modern reverse osmosis unit can also be removed particle, bacterium, spore, virus even Cl ^-Or Ca ⁺⁺Plasma.

On a large scale there are several problems in counter-infiltration (RO) system, and promptly film can be subjected to excess contamination, and will spend great amount of cost for the pressure that produces through film.These two problems are to be mutually related, because great majority or whole known RO devices all need to wash film when operation, so for the penetrating fluid that produces, the quantity of feed liquid is relatively large.The ratio of the penetrating fluid that reclaims in flushing liquor and the seawater desalination is as approximately being 3: 2.Because only some is recovered as fresh water in the seawater that uses,, constituted intrinsic low usefulness situation so wasted the energy that is used to keep water.

In recent years, for usefulness and the reduction corresponding cost that improves the RO device, made multiple effort.The 5th, 229, No. 005 United States Patent (USP) of people such as Fok has been described a kind of method of broadcasting container from a side direction deep-sea of ship.Have the RO film on the surface of this container, be put into about 700 meters dark places, the pressure of this degree of depth is enough to force fresh water to see through film to enter container.After container was full of fresh water, it was raised back on the ship and emptying.In order to increase work efficiency, this inventor also advises another kind of mode, promptly alternately emits and two such containers of emptying.Although this claimed method is that effectively discontinuous process makes it and can not provide sweet water in large quantities in the mode of economy.

The 4th, 512, No. 886 United States Patent (USP)s of people such as Hick have been discussed the another kind of method that can improve the RO installation cost.Here, the RO assembly is placed on the certain depth in the ocean, and the insufficient pressure around this degree of depth assembly is to handle film, and still, this depth pressure is added the additonal pressure that is produced by pump just to be enough to handle film.Therefore, be used to the energy from the wave of top, the water of pressurized is by force feed and pass the RO assembly, and fresh water is discharged from an end of assembly, and seawater is then discharged from the other end.But this device only limits to have the place of tangible wave action, and under arbitrary environment, the expense of installing and handling is all very high.

The 3rd, 456, No. 802 United States Patent (USP)s of people such as Cole have been discussed the another kind of method that can improve the RO installation cost.At this, several RO elements are placed on the enough degree of depth place in the ocean, and from the teeth outwards, pre-filtered seawater is filtered and is transported in the element by pipe.Then, the fresh water of exporting from element is pumped back into the surface, and flushing water turns back to the sea simultaneously.Utilize this device, people such as Cole claim by applying pre-filtered salt solution to film and improving the flushing rate, have improved the life-span of film.But, the shortcoming of this device be still need be positioned at the seawater depths and change the RO element very difficult.

The 4th, 125, No. 463 United States Patent (USP)s of people such as Chenoweth have solved the problem that the desalination action need carries out in the seawater depths, and the content of this patent is incorporated herein as a reference.In the patent of Chenoweth, a plurality of pellicle assemblies are placed in the well or in other underground hole.The seawater film of flowing through from top to bottom, the static pressure of seawater makes penetrating fluid pass film.Then, penetrating fluid (being water purification here) is sucked out this system by lifter.The major advantage of Chenoweth patent is that the energy expenditure of pumping water purification greatly reduces.

Although Chenoweth greatly reduces energy expenditure, this design is still unpractiaca.At first, the design of Chenoweth hints out that central lifter is surrounded by five satellite-type RO device groups in the different degree of depth.Each satellite equipments all has its oneself gatherer, and the liquid stream in each gatherer of each group is assembled in menifold and flow to central lifter.This design has intrinsic poor efficiency.Satellite RO device is gathered bunchy can increase unnecessary complexity and expense, and on same horizontal plane, a plurality of satellite shells can be wasted valuable irrigation canals and ditches space.

Therefore, still have a kind of like this needs, promptly be desirable to provide a kind of apparatus and method that adopt the pressure filtration method to purify a large amount of fluids at low cost.

Summary of the invention

In apparatus and method provided by the invention, the top pressure that is produced by fluid weight is used to drive a plurality of filters to produce penetrating fluid, and at least some horizontal planes of this device (promptly at certain depth), 30% the penetrating fluid that is produced at least is collected in the independent filter housings.Therefore, the present invention reduces or has eliminated boundling work in sewerage or other filtration system, and has improved efficient, has reduced expense.

In a preferred embodiment, nearly all filtering material that is arranged in given depth all becomes web-like at an independent filter housings around one or more permeate collection device.In other preferred embodiment, filter and whole collecting pipe have formed one group of inner core of producing assembly.In a particularly preferred embodiment, each production assembly also comprises a transit area and a transit area that is used to transmit penetrating fluid that is used to transmit seawater.

In others, the end of contiguous production assembly can be designed to the form of utilizing the sliding connection part to be connected with each other, and produces assembly and can keep the relation that matches with support wirerope or bar by connector.

In another aspect of this invention, can adopt submersible pump to promote penetrating fluid to the surface.In having the preferred embodiment of this feature, pump utilizes centrifugal at least and/or the air-lift unit principle is carried out work, when adopting the air-lift unit principle, also can adopt energy recovery system, so that recover energy from the fluid that promotes and gas.In addition, preferably adopting the gas that produces by electrolysis to help pump aspirates.

On the other hand, can be by pipe from such as providing feed liquid salt solution such as ocean or bay or the little buck, described pipe has and prevents to stop up and removable portal plug.In addition, preferably adopt and shovel spade under water this pipe is laid, on one side promptly pipe is laid in ditching on one side.

Describe in detail

In Fig. 1, filter system 10 generally comprises derrick 11, a plurality of changing-over assembly 60, pump assembly 50, an a plurality of production assembly 40 and supports the wirerope 23 of various assemblies.Derrick 11 and each assembly 60,50,40 gather together, and have formed feed liquid passage 18, permeate passageway 18A and passage of irrigation fluid 19.

The various assemblies of system 10 can be arranged in hoistway or other irrigation canals and ditches (not shown), perhaps are arranged in open ocean or other waters (not shown).Under the occasion that is positioned at hoistway or other irrigation canals and ditches, among passage 18, the 18A or 19 one is preferably between the liner 20 of the shell of assembly 60,50,40 and irrigation canals and ditches and forms an annular space.In case system 10 is placed in ocean or other open water, 18,19 of feed liquid and passage of irrigation fluid comprise open liquid basin respectively.

Term used herein " irrigation canals and ditches " is often referred to the space that has dark and narrow relatively part and include fluid.Therefore, ocean, bay, lake or other big waters can not be considered as irrigation canals and ditches described here, because the range in these waters is much bigger with respect to its degree of depth.On the contrary, well or oil well, perhaps irrigation canals and ditches described here can be thought in the underground hole that links to each other by passage.Have the more irrigation canals and ditches of minor diameter although also can use, described irrigation canals and ditches preferably have effective internal diameter of at least 6 inches.The liner of irrigation canals and ditches is not a particular importance, and suitable irrigation canals and ditches can have common steel, cast iron, concrete or other housing, and perhaps irrigation canals and ditches not are with housing.Under a variety of situations, the irrigation canals and ditches that the present invention adopts can be positioned at the place near ocean or other salt solution or little buck, and these waters have formed water source easily.In this case, irrigation canals and ditches can descend a position from the waters, and perhaps a position from the land descends.In other cases, also can adopt the another kind of irrigation canals and ditches that are fit to, these irrigation canals and ditches have several kilometers apart from the water source.Suitable irrigation canals and ditches can not be vertically oriented yet, but tilt.In a word, apparatus and method described here can adopt multiple multi-form irrigation canals and ditches, and no matter original purpose, shape, orientation and the position of these irrigation canals and ditches how.

At derrick 11 places, for example can comprise that the feed liquid of salt solution or seawater is supplied to system 10 by feed liquid supply source 12, simultaneously, waste liquid is discharged from flushing liquor (flushing liquid) outlet 14, and decontaminating liquid (penetrating fluid) is discharged from penetrating fluid outlet 13.Feed liquid supply source 12, penetrating fluid outlet 13 and flushing liquor outlet 14 can be soldered to or otherwise be fixed on the derrick 11.In a specific preferred embodiment, system 10 can be forced into about 3 crust by feed pump 56.This helps to overcome friction loss, the head loss when passing through production assembly 40 and the friction loss in the passage of irrigation fluid 19 in the feed liquid passage 18.

According to the particle concentration in the feed liquid, also optionally adopt pre-filtration system 57.Also can adopt receiving magazine 58 to receive penetrating fluid.

Changing-over assembly 60 is mainly used between derrick 11 and pump assembly 50 and forms pipeline.Therefore, changing-over assembly 60 can design quite simply, for example can be a pipe that is nested with in the pipe (not shown), perhaps one or more collecting pipe (not shown)s that are arranged side by side.

Pump assembly 50 generally includes centrifugal pump or other pump 53, and it is promoted to derrick 11 with penetrating fluid from producing assembly 40.Pump 53 is normally electronic, can adopt the cable (not shown) to give pump with power delivery.The pump of another kind of replacement form can adopt other energy to be driven, and for example compressed air, particularly pump 53 can comprise air lift or utilize the sundstrand pump (composite pump) of air-lift unit principle.In this case, used gas can contract in surface pressure and send pump to by high-pressure air pipe, perhaps produces at least a portion gas by electrolysis in the position of pump or close pump.In other embodiments, system 10 can comprise a plurality of pump assembly (not shown)s, and perhaps an independent pump assembly can comprise a plurality of pumps.A kind of device preferably is provided, and it need not to remove changing-over assembly 60 just can make pump 53 promote and decline, and this can realize by adopting pump that wirerope 51 is installed.

Can adopt pump 53 to be reduced to about 1 crust, and under the pressure of 60 to 70 crust, penetrating fluid is discharged to permeate passageway 18A will suck malleation only.The local at least concentration with the degree of depth and feed liquid salt of actual discharge pressure changes, and this degree of depth is to be lower than the degree of depth that pump 53 is installed the surface.

Produce assembly 40 and generally include an inhalation part 70 and a plurality of adjacent filter element 30.Inhalation part 70 will directly supply to from the feed liquid of feed liquid passage 18 and go up or descend most filter element 30 most, and flushing liquor is left from filter 35 guiding in the filter element 30.As following will the detailed description in detail with reference to figure 2, filter element 30 comprises one or more filter 35, and these filters are separated into penetrating fluid and flushing liquor with feed liquid.

Produce assembly and preferably place about at least 50 meters degree of depth.This degree of depth is enough in the counter-infiltration of using the little buck of realization under the existing film situation, along with the improvement of thin film technique, produces assembly and can work well under less than 50 meters the degree of depth.On the other hand, this system preferably adopts and is fit to the filter of the degree of depth on a large scale, and these degree of depth comprise at least 100 meters, at least 250 meters, at least 350 meters, at least 500 meters, at least 750 meters and at least 1000 meters.

The present invention has also adopted wirerope 23, is used for each assembly 60,50,40 is secured together and supports their weight.As following will the detailed description in detail with reference to figure 5, wirerope 23 can replace with excellent (not shown), bar (not shown), belt (not shown) or other supporter, also they all can be omitted, and replace other support and jockey between adjacent component.

During actual the use, assembly 60,50,40 can be configured to any size and dimension that is suitable for work, and adopts any suitable material, and is not that all assemblies all must have same structure or composition characteristic.For convenience and reduce expenses, changing-over assembly 60, penetrating fluid pump installation 50 and produce assembly 40 and preferably be roughly tubulose, and make by suitable material.Particularly can adopt such as PVC, epoxy resin fiberglass, stainless steel or other steel as construction material.Can also adopt other construction material that comprises new component or new material.

During work, the end of producing assembly 40 interconnects usually or and puts to form a chain.At the top of uppermost production assembly, be provided with one or more pump assembly 50, again changing-over assembly 60 is attached to the top of pump assembly and arrives derrick 11 places.Utilize Fig. 6 or device shown in Figure 7 to make these assemblies drop to the zone of an opening or the desired depth in the irrigation canals and ditches.

Preferably adopt the slidable fit connector that these assemblies are linked to each other.In another alternative embodiment, also can utilize other device, comprise that threaded connector, clip, bolt or adhesive connect two or more assemblies.

System of the present invention is preferably with some bracing or strutting arrangement, and this can comprise one or more building, pump case and other device.Although not clearly expression should be understood that also feed liquid can be through pre-filtered, this pre-filtering operation can be carried out in the arbitrary position that penetrates feed liquid supply source 12 upstreams that produce assembly 40.For long-term protection filtering material; it is important relatively that the salt solution that aspirates from waters such as bay or ocean is carried out pre-filtered ability, and make apparatus and method of the present invention than only filter is placed in the open ocean and only rely on natural flows or the flushing action that obtains through the pumps water of filter better.

Referring to Fig. 2, produce assembly 40 and generally include one or more filter assemblies 30 and independent changing-over parts 70.Each filter assemblies 30 comprises a shell 31, an annular space 19A and an one or more filter assemblies 44.Shown in Fig. 8 A-8E, each filter assemblies 44 preferably includes one or more filter housings 32, and each housing can hold a plurality of filter vane 35 and the dividing plate 41 that links to each other with collecting pipe 33.

As following going through, Fig. 2 has represented a plurality of inlet holes 74 that are positioned at suction assembly 70, and they make from the fluid of feed liquid passage 18 by spoke 77 and enter the feed flow zone 78 of filter.

Fig. 2 has also represented a kind of possibility jockey 22 between wirerope 23 and production assembly 40 in detail.This connector can be positioned on the arbitrary position or a plurality of position that produce assembly 40, but preferably this a connection piece is positioned near the top and bottom that produces assembly 40.

Although not expression has multiple replacement form for producing assembly in existing accompanying drawing, these forms are consistent with design of the present invention.For example, it is annular that the annular fluid transmission space in the production assembly 40 can need not to be, and production assembly 40 also needn't comprise the fluid transmission region.As described below, feed liquid can transmit in the space that produces between assembly and the irrigation canals and ditches liner, and also can transmit feed liquid or penetrating fluid in leading to the independent pipeline of producing assembly or space.Similarly, in other alternative embodiment of filter vane 35, dividing plate 41 and gatherer pipeline also can be provided with to be different from illustrated mode.

In Fig. 3, preferred set-up mode includes three filter components 30, and they are supported by independent changing-over parts 70.But, be preferably in more or filter component still less 30 is set between each changing-over parts 70, special wish that the filtration system that is adopted has the filter component 30 of five series connection when brine desalination, they between changing-over parts 70, each filter component 30 nearly 6 meters long.It is very favorable that five parts are installed, because this is believed to reach balanced flow (flushing) rate and the rate of recovery that overcomes pressure drop.

Arrow among Fig. 4 and Fig. 5 is used to indicate may flowing to of feed liquid.In illustrated specific embodiment, feed liquid flows into import 74 downwards along passage 18, flows to filter feed flow zone 78 along spoke 77 again.Then, feed liquid flows downward, and through dividing plate 41 (seeing Fig. 8 C), is separated into independently liquid stream of two strands of penetrating fluid and flushing liquors at the dividing plate place by filtering material 45.Then penetrating fluid passes collector aperture 34 and enters collecting pipe 33, upwards flows to infiltration liquid pump 53 more therefrom.Simultaneously, flushing liquor continues to flow downward and passes the dividing plate 41 of one or more filter components 44, when it reaches the collection space 79 that is arranged in next bottom changing-over parts 70 till.Then, flushing liquor leaves changing-over parts 70 and is upward through continuous top and produces assembly 40, pump assembly 50 (not shown)s and changing-over assembly 60 (not shown)s and arrive in the derrick (not shown).

In Fig. 6, top changing-over assembly 60U can link to each other or throw off and be connected with bottom changing-over assembly 60L.In this particular example, each transfer assembly 60U, 60L all have in an outer tube 61 and one and manage 62.Outer tube 61 connects by slidable fit connector 61A, and interior pipe 62 connects by slidable fit connector 62A.In addition, sealing ring 6 1B and 6 2B are respectively applied for sealing pipe 61 and 62.In addition, guide rail or spoke (not shown) are set selectively in many annular spaces, for example between pipe 61 and 62 and between pipe 61 and irrigation canals and ditches liner 20.Certainly, as mentioned above, connector shown in Figure 6 only is used to represent embodiment, also can adopt other type of attachment and connector in fact.

Look at wirerope now, wirerope 23 comprises upper steel cable-end 27, hoist point 28, supporting-point 29 and bottom wirerope end 26.Connecting pin 27 is used for fixing the connector of adjacent wirerope 23, and wire clip 25 is used for wirerope 23 is connected to assembly 60.Although should be understood that each wirerope is the same long with assembly 60 in this particular example, each wirerope also can be longer or short than the assembly of correspondence, and an independent wirerope can be the same with the whole length of system 10.Wire clip 25 shown in it should also be understood that here and Fig. 2 and wire clip 22 shown in Figure 3 are different, also can adopt the wire clip or the clamping device of other form.

Lifting device 80 can be used for assembling or disassembling system 10.This device can have multiple possible moulding, comprises the device 80 that has flexible support member 82 and bar 81 shown in the figure.

Fig. 7 has represented a light mechanical lifting assembly 90, and it comprises a flexible support member 92 and bar 91.Also represented a lifting piece 95 among the figure, it is used for pinning upper steel cable-end 27 and promotes or put down arbitrary assembly 60,50,40.Lifting subassembly 90 can comprise movably control panel 94 with any control of controller easily.

In the preferred embodiment shown in Fig. 8 A and the 8B, the filter of two or more separation is folding and bond on the filter vane 35, and with space bar 41 1 super helixs round collecting pipe 33.This structure can form the high-pressure side and the low-pressure side of filter vane 35.Should be understood that and also needn't constitute described coiling around the filter vane 35 of collecting pipe 33 settings for configuration more than one.In other alternative embodiment, filter vane is partly reeled and/or partly folding around collecting pipe 33.

Fig. 8 C has represented the detail of the preferred embodiment of filter 35.Here, in each side of penetrating fluid loading material 42, each filter vane 35 includes a filtering material layer 45.Penetrating fluid loading material 42 seals at seal 43 places, and discharges to the collection hole 34 of collecting pipe 33.As mentioned above, dividing plate 41 is arranged between the overlapping filter vane 35.The feed liquid of not passing filter vane 35 will continue to wash the high-pressure side of blade 35, and finally flow out these systems by passage of irrigation fluid 19.

Here said filtering material 45 preferably includes but the film that also is not limited to use in the counter-infiltration operation.Like this, the present invention can adopt for filtering macro particle (100 to 1000 microns), microscopic particles (1.0 to 100 microns), macro molecules particle (0.1 to 1.0 micron), molecule particle (0.001 to 0.1 micron) or ion (less than 0.001 to 0.001 micron).Perhaps or even molecular breakdown, the hydrogen that for example separates from oxygen in hydrolysis following filter will improve filter area, even comprise littler particulate.In this manner, described technology will cover the whole filter area of liquid.This filter area will comprise that particle filters, and follow-up micro particle filtering, ultrafiltration, millimicro filtration and osmosis filtration.

Independent shell 31 preferably includes a plurality of filtration housings 32.In such an embodiment, can adopt a plurality of filters 33, still effectively use simultaneously the space in the filter housings 32, this embodiment has satisfied a kind of like this requirement for restriction on some horizontal plane at least of this device, that is: for arbitrary given horizontal plane, 30% the permeate collection that is produced at least is in independent filter component 30.In other preferred embodiments, 40%, 60% is collected into the independent filter component 30 that is arranged in arbitrary given depth until whole penetrating fluids that produce almost.

In some preferred embodiments, also can provide a plurality of filter components 30 in the given degree of depth.But in order to reach the application's purpose, select 30% can distinguish with the patent of Chenoweth and than having tangible advantage for limit.In the patent of Chenoweth, five different film assemblies are always arranged at each producing zone.That selects obviously can hold a plurality of common diaphragm unit bundles effectively in the given degree of depth in the circle wellhole.Although Chenoweth does not hint or advise this improved form, but still can only provide three different film assemblies at each production degree of depth place.This film assembly bundle can produce about 1/3rd penetrating fluid in the given degree of depth, among each of described three filter housings, has therefore selected 30% to be limit.

Take another look at other embodiment, permeate collection pipe 33A preferably is positioned on the position of non-central authorities (shown in Fig. 8 D and 8E), and perhaps gatherer is positioned at the outside of filter component fully.For example, one or more gatherer (not shown) can be positioned at the inboard that produces assembly 40, and penetrating fluid can flow to the space outerpace that comprises a new annulation (not shown) from gatherer.Overcome this limit and be that the penetrating fluid above 30% that produces on some horizontal plane at least of this device, at given depth is collected in the independent filter component 30.

Certainly, shown in the present invention is not limited only to here and described embodiment.In alternative embodiment, for example, any all counter-infiltration in this way of liquid stream.In addition, the multiple fluid passage can exchange.Like this, in Fig. 2, flush fluid will be discharged from exporting 74, rather than flow to mouthful 74 discharges from feed liquid.In another kind of embodiment, system and method as herein described also can be used for decontaminate food, and for example orange juice perhaps separates different industrial chemistry materials.Therefore, although the present invention represents and has described specific embodiment that under the situation that does not break away from the present invention's design, those skilled in the art can make many distortion.The present invention is limited within the spiritual scope of claims.
