The present invention is further the replenishing of the application for a patent for invention file " compact efficient low-energy consumption magnetic force air separating technique art " that belongs to same inventor and " compact efficient low-energy consumption magnetic force air separating technique art (two) ", flexible and expansion, the Chinese patent application day of said application for a patent for invention file " compact efficient low-energy consumption magnetic force air separating technique art " is on February 20th, 1997, Chinese patent application number is 97100910.4, and predetermined open day is on October 8th, 1997; The Chinese patent application day of said " compact efficient low-energy consumption magnetic force air separating technique art (two) " is on September 12nd, 1997, and Chinese patent application number is 97118314.7.
Obtain oxygen and nitrogen from air, method commonly used now has three kinds, and they are cryogenic rectification method, pressure swing adsorption method and membrane separation technique.Cryogenic rectification method is to utilize the boiling point difference between the gas component such as oxygen and nitrogen in the liquefied air to realize what rectifying separated, and this method developing history is of a specified duration, technology maturation.Pressure swing adsorption method is to utilize molecular sieve that oxygen in the air and nitrogen budgets adsorbance are had nothing in common with each other, and by changing system pressure, realizes the circulation of absorption and desorption process, reaches oxygen and nitrogen separation purpose.Membrane separation technique is to utilize the film with selective permeation function, under the ambient pressure effect, makes airborne oxygen and nitrogen selectively by membrane interface, reaches the air separation purpose.Cryogenic rectification method and pressure swing adsorption method technology maturation, gas production height, but equipment complexity, the operating cost height is controlled loaded down with trivial details; Though and membrane separation technique equipment is simple, operate also simply, make the film difficulty, the service life of film is shorter, and resistance was big when film was passed through in the gas infiltration, and the gas permeation flux is little, gas production is little, in addition, membrane separation plant is bulky, is unfavorable for using, in a word, technical can't be satisfactory.Three kinds of above-mentioned air separating methods, energy consumption is all than higher, with the lower slightly membrane separation technique of energy consumption comparatively speaking wherein is example, " membrane science and technology " magazine 1989 the 1st phases the 39th page to 41 pages introductions according to No. 508 " membrane science and technology " editorial offices publication in Chinese Duanjiatan, Lanzhou City, Gansu Province, and, the Chinese magazine of editing and publishing according to No. 108 Jilin Province research institutes of scientific-technical information in Stalin street, Chinese Changchun " science and technology of Japan " the 3rd phase in 1986 the 25th page to the 26th page introduction, produce 12 liters of oxygen content with film separation oxygen enrichment device per minute and be about 30% to 40% oxygen-enriched air, required consumed power power is about 300 watts to 340 watts, the size of the film separation oxygen enrichment device that this example relates to is about long 70 centimetres, wide 40 centimetres, high 80 centimetres, the weight of this device is about 100 kilograms.
Except previously described three kinds of air separating methods commonly used, other has and a kind ofly carries out the method for air separation with magnetic force, and it is a special nature of having utilized oxygen can be attracted consumingly in non-uniform magnetic field.Scientific and Technical Information Institute of China edits according to Beijing, the the 36th to 37 page of " the external techwatch " that Beijing scientific and technical literature publishing house publishes the 1st phase in 1988, and, the International Department of China Newspaper Office of Patent Right edits, " world inventions " 1989 the 6th phases the 6th page to the 8th page introduction that Beijing China Newspaper Office of Patent Right publishes, patent documentations such as Japanese Patent Publication 42-15361 have showed that a kind of ambient magnetic separates oxygenerating technology, principle and device that this ambient magnetic separates oxygenerating technology are such: air is entered in the cylindrical container, inwall at this cylindrical container inwardly is being arranged in order permanent-magnet block group and electromagnet group from nozzle, feeding heavy current makes each electromagnet keep strong magnetic field, when air flows in cylindrical container through out-of-date, airborne oxygen molecule, since well-known can be by the character of magnetic field suction, by magnetic field suction near permanent-magnet block that is placed in the cylindrical container inner wall surface and electromagnet, like this, staying near the air of cylindrical container inner axes is exactly the nitrogen-rich air of anoxic, and the air of close cylindrical container inwall, it is exactly oxygen-enriched air, so, in a not too big space, mainly be the high-intensity magnetic field that utilizes electromagnet, make airborne oxygen and nitrogen separation.Use this device, can obtain oxygen-enriched air and nitrogen-rich air simultaneously, and, it is not too big to take up room, but, need to consume a large amount of electric energy and keep the high magnetic field intensity that produces by electromagnet group, simultaneously, also must manage to solve electromagnet group because of the heating, the intensification problem that produce by big electric current, these weak points make this oxygenerating technology be restricted on using; The weak point of this technique device also is, though in this technique device, used some permanent-magnet blocks, those permanent-magnet blocks the orientation is set, set-up mode makes those permanent-magnet blocks in fact almost can not bring into play useful effect.Except that above-mentioned ambient magnetic separates oxygenerator, Gazette of Patent for Invention and utility model patent communique by retrieval, can know, in recent years, there is the patent document that relates to magnetic air separation tech to deliver successively, still, wherein Jue Dabufen inventive concept, all be to attempt to reach the purpose that big flow obtains oxygen-enriched air with quantity permanent magnet seldom, and such purpose, only by utilizing permanent magnet in a small amount in fact to be difficult to reach.
In actual applications, the common expectation of people can big practically flow ground obtains oxygen-enriched air, under such prerequisite, people just can notice how to reduce system gas energy consumption, reduce the system pneumatolytic this, reduce device volume, alleviator weight or the like problem.
Airborne nitrogen, aqueous vapor, carbon dioxide and hydrogen etc. are the compositions of weak inverse magnetic, they can be subjected to slight repulsive force in magnetic field, and airborne another important composition oxygen has strong paramagnetism, it can be subjected to strong attraction in uneven magnetic field, this is a well-known phenomenon.The 434th page to 438 pages introductions of E.M. Po Saier work " study course of Berkeley physics " second volume " electromagnetism " Chinese translation of volume according in June, 1979 publication of BeiJing, China's scientific publication, if experimentize with liquid oxygen, in magnetic field intensity is 18000 Gausses, magnetic field gradient is under the condition of 1700 gauss/cm, oxygen molecule will be subjected to being equivalent to the strength of its own wt octuple toward the suction of magnetic field lira, this shows that this attraction is big.Carry in passing a bit, according to physics principle, as can be known, for the oxygen molecule in being in free vacant state, under said circumstances, be subjected to the sucking action of non-uniform magnetic field, oxygen molecule will orientation accelerate to the high-speed of about 80 meter per seconds within a second, and continue to quicken, rush at high speed in the said non-uniform magnetic field to the strongest position of oxygen molecule attraction.When normal temperature, non-uniform magnetic field remains big to the attraction of oxygen molecule, contain the airborne numerous oxygen molecules of oxygen and be subjected to the attraction of non-uniform magnetic field and produce directed movement to cause the air-flow that is called as " magnetic wind ", this phenomenon also is the scientific basis that contains the Magnetic Measurement Technology of oxygen content in the oxygen air.
Known magnetic field is to be directly proportional with the product of magnetic field intensity and magnetic field gradient to the attraction of oxygen molecule, that is to say that magnetic field both was directly proportional with magnetic field intensity to the attraction of oxygen molecule, was directly proportional with magnetic field gradient again; Therefore, higher when magnetic field intensity, and magnetic field gradient hour, and magnetic field is not strong to the attraction of oxygen molecule; And not really high in magnetic field intensity, but in the bigger magnetic field of magnetic field gradient, the attraction that oxygen molecule is subjected to but can be stronger.Said magnetic field gradient is meant the rate of change of magnetic field intensity with distance.Between the big field regions of the product value of magnetic field gradient and magnetic field intensity oxygen molecule had bigger attraction.
The present invention's's (series) main purpose provides the technology of obtaining oxygen and nitrogen from air of flow air feed greatly a kind of compactness, high efficiency, low energy consumption.The present invention's (series) utilizes the oxygen molecule can be by the strong special nature that attracts in magnetic field, from air, obtain oxygen and nitrogen, but, with existing magnetic air separation tech differently, the present invention's (series) is from new design philosophy, has overcome little or the like the deficiency of the big and actual gas supply flow of energy consumption in the existing magnetic air separation tech fully.The present invention's (series) emphasizes the sphere of action of expansion field to air, and, utilize the not permanent magnet of consumed power fully, all sidedly.The present invention's (series) only with permanent magnet as the magnetic field supplier.The present invention's (series) passes through permanent magnet, particularly tabular have hole or an imperforate permanent magnet, in limited space, do rational, compact arrangement, reach the purpose of following two aspects: the first, utilize the permanent magnet manufacturing that the magnetic field of high magnetic field gradient and magnetic field intensity product value is arranged, it two is, expand effective active area significantly to the compellent magnetic field of oxygen, this that is to say, the high magnetic field of the product value of magnetic field gradient and magnetic field intensity and the effect interface of air are expanded significantly.
The present invention is achieved in that and uses many permanent magnets, said permanent magnet is the permanent magnet that contains hole, the said permanent magnet that contains hole is to do closely-spaced arrangement, many permanent magnets of doing closely-spaced arrangement form rib group shape structure, rib cohort shape structure, wing group shape structure, wing cohort shape structure, bunch shape structure, paliform structure or layer structure, wherein, the installation position of the hole of adjacent permanent is corresponding mutually, the hole that many said installation positions are corresponding mutually overlaps the link passage continuously, and, clamping frame, the said rib group shape structure that is arranged in, rib cohort shape structure, wing group shape structure, wing cohort shape structure, bunch shape structure, the permanent magnet of paliform structure or layer structure is to fix with said clamping frame, among the present invention, will comprise that the device of said modules is called the compact efficient low-energy consumption air-magnetism separating device.When the magnetic field of the permanent magnet in the said air-magnetism separating device bunch when containing the oxygen source air and contact, be subjected to the attraction in magnetic field, the oxygen molecule that contains the airborne over paramagnetism of oxygen source just moves to the direction of permanent magnet bunch, like this, the clearance space of said permanent magnet bunch and near the airborne oxygen content in space just be higher than the oxygen content that contains the oxygen source air, the relative higher air contact in slit on the sidewall of said link passage with oxygen content, when such link passage is communicated with the inlet channel of compressor, start compressor, so, air via the output of the outlet passageway of compressor, be exactly the higher relatively air of oxygen content, just oxygen-enriched air; Being used to aspirate the machinery of oxygen-enriched air, can also be the machinery with self-holding gettering ability, for example the petrol engine of some kinds.
In said air-magnetism separating device, the mutual close magnetic pole of permanent magnets adjacent both can be the different magnetic pole of magnetic polarity, it also can be the identical magnetic pole of magnetic polarity, it can also be the situation between these two kinds of situations, but, because high-gradient magnetic field has bigger attraction to oxygen molecule, thereby, the best arrangement mode of said permanent magnet is that to make the mutual close magnetic pole of permanent magnets adjacent be the identical magnetic pole of magnetic polarity.With the pole surface residual magnetization is that 2500 Gausses' permanent magnet is an example, when the mutual close magnetic pole of permanent magnets adjacent is the identical magnetic pole of magnetic polarity, and, when distance between two poles is about 0.5 centimetre, so, said magnetic pole gap and near magnetic field gradient can reach about 10000 gauss/cm, when distance between two poles is about 0.2 centimetre, said magnetic pole gap and near magnetic field gradient can reach about 25000 gauss/cm; And if adopt the pole surface residual magnetization to be about 1000 Gausses' permanent magnet, and be still with the identical magnetic pole of magnetic polarity close mutually, so, when distance between two poles is about 0.2 centimetre, such magnetic pole gap and near magnetic field gradient can reach about 10000 gauss/cm, when distance between two poles is about 0.1 centimetre, said magnetic pole gap and near magnetic field gradient can reach about 20000 gauss/cm; Even use pole surface remanent magnetism that 500 Gausses' permanent magnet is only arranged, under similar situation, when distance between two poles was about 0.2 centimetre to 0.1 centimetre, magnetic field gradient value also can reach about 5000 gauss/cm to 10000 gauss/cm.
In said air-magnetism separating device, the said permanent magnet that contains hole can be the permanent magnet of arbitrary shape.The present invention emphasizes the useful effect interface between the expansion field and air in the confined space, and adopting the tabular permanent magnet that contains hole is the selection that helps realizing the object of the invention most.The said tabular permanent magnet that contains hole of the present invention comprises that thickness contains the tabular permanent magnet of hole uniformly, and, the tabular permanent magnet that contains hole that has thickness to change.The said tabular permanent magnet that contains hole of the present invention can certainly comprise that the plate face is the tabular permanent magnet that contains hole of curve form.The said mode of magnetization that contains the permanent magnet of hole can be the mode of magnetization arbitrarily, for example, can be bipolar magnetization, also can be multipole magnetized; The direction of magnetization can arbitrary orientation.The said optimum mode of magnetization that contains the tabular permanent magnet of hole is the bipolar mode of magnetization; The optimum direction of magnetization is that vertically to divide equally section mutually vertical or approach orthogonal direction with the said maximum that contains the tabular permanent magnet of hole.
The said permanent magnet that contains hole can be the permanent magnet that contains single hole, also can be the permanent magnet that contains two or three or four or five or contain more a plurality of holes, and the number of said hole is not limit.
The shape of the hole of the said permanent magnet that contains hole is not limit, and for example, said hole can be hole of circle, ellipse, streamlined, strip, polygon or gear shape or the like.The shape of the surrounding edge of the said permanent magnet that contains hole is not limit, and for example, the shape of the surrounding edge of said permanent magnet can be circle, ellipse, streamlined, gear shape, strip or polygon or the like.
The shape and the structure of said clamping frame are not limit, for example, clamping frame of grid group structure, cage structure, cage group shape structure, rack group structure or clamping plate group structure or the like can be adopted, certainly, in said clamping frame, also appendicles such as some structural connections and screw, nut, seal can be comprised.Clamping frame with said clamping plate group structure is an example, and specifically, this clamping frame mainly is to be made of clamping plate and clamping plate connector.Said clamping plate for example tabular clamping plate, plate face are the flute profile clamping plate of clamping plate, plate-like clamping plate, peviform clamping plate or plate face curved edge of clamping plate, the plate face complications of curve form.Said clamping plate connector for example cross section is the sub-assembly that mixes of the rod, plate shape of arbitrary shape, tubular, bar group shape, plate group shape, pipe group clevis plate connector or said rod, plate shape, tubular clamping plate connector.In the built up construction of said clamping plate and clamping plate connector, can certainly comprise appendicles such as screw, nut, seal.In said clamping plate, having clamping plate at least is the clamping plate that contain hole, and said link passage is communicated with the said hole that contains the clamping plate of hole.Best embodiment is to make each clamping plate all contain hole.The quantity of the hole of the said clamping plate that contain hole is not limit, and for example can be to contain one, two, three, four or more hole.Said clamping plate connector both can penetrate the said hole that contains the permanent magnet of hole and connect adjacent clamping plate, also can connect adjacent clamping plate without said hole, certainly, can also be to connect adjacent clamping plate with the two promiscuous mode that haves both at the same time.For contain many holes permanent magnet for, both can make each said hole all have the clamping plate connector to pass, also can only there be the minority hole to be passed by the clamping plate connector, perhaps, connector is avoided said hole fully, but connects adjacent clamping plate through the surrounding edge of said permanent magnet, again or, employing mixes connected mode, all is fine.
As a kind of embodiment, the construction package of said clamping frame can be fully by said link passage, in other words, said clamping frame can only grip said permanent magnet in peripheral position, do not take link channel interior space fully, this is the present patent application one of ben content that case is wanted.
In said air-magnetism separating device, when the mutual close magnetic pole of permanent magnets adjacent is the identical magnetic pole of magnetic polarity, in such magnetic pole gap and near will the magnetic field of high magnetic field gradients value appears having, but, distribution scenario in the magnitude of field intensity distribution scenario of the same space and magnetic field gradient size is different, for example, to have magnetic field intensity in the middle of the magnetic pole gap be zero or approach zero interface, this interface and near, though magnetic field gradient value is big, but field strength value is too little, thereby make the product value of magnetic field gradient and magnetic field intensity less than normal, therefore, such interface and near the magnetic field in interval little to the oxygen molecule attraction; Be zero or approach zero interface and set out by said magnetic field intensity, more be near pole surface, magnetic field intensity is big more, up to the maximum that on pole surface, reaches magnetic field intensity, that is to say, in pole surface and that part of interval of being close to nearly pole surface, the product value maximum of magnetic field intensity and magnetic field gradient, attraction to oxygen molecule is also the strongest, when the permanent magnet in the said air-magnetism separating device when containing the oxygen source air and contact, be subjected to the attraction in magnetic field, the gap of said permanent magnet bunch and near the space will put aside the higher relatively air of oxygen content, but, since magnetic pole gap and near exist the Distribution of Magnetic Field strong and weak uneven to the oxygen molecule attraction, the result correspondingly causes existing the uneven distribution of oxygen content size in such interval, more be near pole surface, oxygen content is big more, in pole surface and be close in the interval of nearly pole surface the highest oxygen content is arranged, and the magnetic field intensity in the middle of said magnetic pole gap be zero or approach zero said interface and near the interval, the oxygen molecule attraction is zero or approaches zero, thereby should for pole surface and near interval thereof, want little many by the interval oxygen content.The height that oxygen content is not carefully distinguished with magnetic pole gap and near air thereof in slit if leave on the said link channel side wall sucks in the said link passage in the lump, though the result can obtain oxygen-enriched air, but this oxygen-enriched air may be to come from the oxygen molecule attraction is zero or approaches between zero said interface region more, because should the interval air carry the baby lessly, be easier to comparatively speaking flow; And the hyperoxic air of being close to nearly pole surface is fettered by magnetic field, and comparatively speaking, it is slow to flow.Do not take additional measures, only draw oxygen-enriched air in the above described manner roughly, be fine certainly, but effect is not the most desirable, because the oxygen-enriched air oxygen content that obtains is not high like this.For obtaining high oxygen containing oxygen-enriched air, should contain the interval oxygen-enriched air of drawing of oxygen from said pole surface and the height of being close to nearly pole surface, should manage the air insulated in said interface that oxygen content is relatively low and near interval thereof simultaneously or cover, stop the relatively low air of oxygen content to enter in the said link passage.The air-magnetism separating device that has further comprised veil is to help obtaining the device of high-quality oxygen content than higher oxygen-enriched air.Said veil is to be used to cover relatively low said interface of oxygen content and near air thereof, and said veil is installed between the adjacent permanent, has air gap between the permanent magnet of said veil and vicinity.Just to contain the oxygen interval corresponding with said pole surface and the height of being close to nearly pole surface for said air gap; The air that sucks said link passage via said air gap is exactly that high-quality oxygen content is than higher oxygen-enriched air.The surrounding edge of said veil is changeable, and the size of its surrounding edge is suitable not hinder contain the oxygen source air mobile to be updated to.The material that is used to make said veil is not limit, and for example can use rubber, plastics, porcelain material, timber and metal material or the like.
In said air-magnetism separating device, the opposed facing plate face of adjacent tabular permanent magnet can be the identical magnetic pole strength of magnetic polarity, preamble is addressed, in this case, when said permanent magnet bunch when containing the oxygen source air and contact, oxygen molecule there is the pole surface of strong attraction and is close in pole surface interval and will gathers the oxygen containing high-quality oxygen-enriched air of height, but, this height that is the lamelliform distribution contains the constraint that the oxygen oxygen-rich air is subjected to magnetic attraction, it is slow to flow, if pole surface magnetic field everywhere is identical or intimate identical to the attraction of oxygen molecule, just is difficult to order about this lamelliform height and contains the oxygen oxygen-rich air and flow to said link channel direction along pole surface.Contain the oxygen oxygen-rich air and flow to said link channel direction in order to order about said filmated height along pole surface, in general, can take following four kinds of schemes, first kind of scheme is, the angle that the said maximum of adjacent tabular permanent magnet is vertically divided equally between the section is acute angle, and makes the direction of this acute angle point to said link passage; Second kind of scheme is to adopt the uneven permanent magnet of pole surface residual magnetization, and make the bigger close said link passage of part of residual magnetization of said permanent magnet; The third scheme is that the tabular permanent magnet that employing has thickness to change, the thickness variation pattern of said tabular permanent magnet are to make the part of the contiguous link passage of permanent magnet that the thickness that increases gradually be arranged; The 4th kind of scheme is to mix two kinds or whole three kinds of schemes using in aforementioned three kinds of schemes; Above-mentioned any scheme can make said pole surface and be close to the magnetic field intensity in interval of nearly pole surface and favourable variation takes place the product value of magnetic field gradient, near the position of link passage, said product value is big more, attraction to oxygen also strengthens thereupon, this has just formed the directed traction to oxygen of pointing to the link passage along said pole surface, so, just, can order about the said slow oxygen containing oxygen-enriched air of filmated height that flows flows to said link channel direction along pole surface.Under said circumstances, if said air-magnetism separating device is the device that has comprised said veil, the said air gap of being close to nearly pole surface so just in time can extract to such an extent that converge continuously and high oxygen containing oxygen-enriched air that the said lamelliform that comes distributes along pole surface with taking advantage of a situation.
General the principles of science according to process fluid flow, we know, when fluid flows between the plate of any materials and plate, it is uneven that the flow rate of fluid distributes, press close to plate face position, the flow rate of fluid is low more, exists the slow laminar boundary layer that flows in the position of pressing close to the plate face; Meanwhile, in the position away from the plate face, the flow rate of fluid can be bigger.In the present invention, if adopt tabular permanent magnet, and the opposed facing plate face that makes adjacent tabular permanent magnet is the identical magnetic pole strength of magnetic polarity, when said permanent magnet with flowing contain the oxygen source air and contact the time, form high oxygen containing oxygen-enriched air layer in the interval of being close to nearly pole surface, the oxygen containing oxygen-enriched air layer of this height is simultaneously also just in time corresponding with said laminar boundary layer under the general situation, but, in the situation that the present invention relates to, because magnetic field is to the strong attraction of the high-quality oxygen-enriched air layer of being close to nearly pole surface, in fact make the density of said layer laminar boundary layer increase, thickness increases, it is more slow to flow, and the air-flow of the relative high velocity flow around the more difficult quilt breaks up.In the magnetic pole space to attract oxygen power be zero or approach in zero the space said interface and near, then be to allow the air-flow high velocity flow.Said oxygen-enriched air layer is in case form, just can stably keep, even if oxygen-enriched air is constantly extracted by the link passage, said oxygen-enriched air layer also can be promptly from around flowing contain and trap high oxygen containing air the oxygen source air, make said oxygen-enriched air layer obtain rapidly replenishing and restoring.For above-mentioned reasons, air-magnetism separating device of the present invention can allow big flow and the renewal of big flow velocity ground and replenish to contain the oxygen source air, and this means that simultaneously air-magnetism separating device provided by the present invention has big oxygen supply potentiality.
The present invention emphasizes in the confined space the effective contact interface between the expansion field and air significantly, therefore, as mentioned before, tabular permanent magnet, the tabular permanent magnet that varied in thickness is particularly arranged is reasonable selection.Obviously, the average thickness of said tabular permanent magnet is more little, help the effective magnetic field area that in the confined space, provides big as far as possible more, but, when the average thickness of said tabular permanent magnet is little to a certain degree the time, mechanical performances such as the fragility of said permanent magnet, impact strength just there has been the higher requirement of ratio.It is various in style to be applied to permanent magnet material of the present invention, and wherein, the permanent magnet of bonding is a kind of reasonable selection that has taken into account mechanical performances such as mouldability and fragility, impact strength.The permanent magnet of said bonding mainly is to mix bonding with magnetic with binding agent to be processed into.Said binding agent is thermoplastic resin, thermosetting resin for example; Said binding agent also can be low melting point metal material, for example metallic tin; Said binding agent can also be an elastomeric material.Said magnetic is ferrite class magnetic, rare earth magnet powders for example.Said rare earth magnet powders is NdFeB magnetic powder, Rare-Earth Cobalt magnetic for example.The permanent magnet of said bonding can adopt many kinds of method moulding, for example can adopt method moulding such as injection moulding, compacting, coating.The permanent magnet of said bonding claims compound permanent-magnet material again.The composition of the permanent magnet of said bonding is except binding agent and magnetic; obviously can also allow the composition that comprises that some are less important, for example colouring agent, surface protection coating and the nonmagnetic tablet or net or the filiform that are clipped in the permanent magnet inside of said bonding.
The said permanent magnet shape of the present invention is not limit; The permanent magnet of said bonding can be formed as the permanent magnet of any setting shape, especially is suitable for being formed as the little tabular permanent magnet of average thickness.
In the said air-magnetism separating device of the present invention, when the opposed facing surface of adjacent permanent is the identical magnetic pole strength of magnetic polarity, also can adopt another special embodiment, this scheme is exactly the poly-magnetic spare that installing is made with magnetic conductive material between adjacent permanent, has air gap between said poly-magnetic spare and permanent magnets adjacent.The surrounding edge size of said poly-magnetic spare is not limit; But, play a role effectively for making poly-magnetic spare, preferably design will gather the surrounding edge protrusion of magnetic spare outside the surrounding edge of adjacent permanent.Better design is to adopt cross section to be the poly-magnetic spare of arrow-shaped or anchor shape or rivet shape or T-square shape or dumb-bell shape, simultaneously, the surrounding edge of this poly-magnetic spare is protruded outside the surrounding edge of adjacent permanent.The effect of said poly-magnetic spare is magnetic line of force pack, concentrating on the flange place discharges, so, the flange place and near the magnetic field intensity thereof of poly-magnetic spare are increased substantially, no matter be to adopt surperficial remanent magnetism to reach 2500 Gausses' permanent magnet, or adopt surperficial remanent magnetism that 500 Gausses' permanent magnet is only arranged, can be by suitable design, the magnetic field intensity at the flange place of said poly-magnetic spare is reached more than about 10000 Gausses, even high magnetic field intensity more.Adopting cross section to be the poly-magnetic spare of arrow-shaped or anchor shape or T-square shape or rivet shape or dumb-bell shape or L font or hook-type, is the optimal design of having taken into account magnetic field intensity, magnetic field gradient, useful effect interface, magnetic field and the anti-gas shock factor of fluid boundary layer.Under said circumstances, the oxygen-enriched air that is adsorbed is to enter said link passage via the air gap between said poly-magnetic spare and the adjacent permanent, is extracted with this path.
In the said air-magnetism separating device of the present invention, allow certainly to select such design: the opposed facing surface that makes adjacent permanent is a magnetic polarity different magnetic poles face.In this case, the opposed facing surface portion ground of adjacent permanent is close together mutually, between so said that part of surface that is close together mutually, has air gap.Oxygen-enriched air enters the link passage via this air gap, is extracted with this path.Observation shows, in the above described manner the installing pole surface and near, the product value of magnetic field intensity and magnetic field gradient still has considerable numerical value, and, this product value is to increase gradually along pole surface, up to reaching maximum at said air gap place, the oxygen molecule that is attracted mainly also is to move to said air gap direction along pole surface, and the characteristic of the anti-gas shock of said layer laminar boundary layer still can play a role in this scheme.
In the said air-magnetism separating device of the present invention, when the opposed facing surface of adjacent permanent is the identical magnetic pole strength of magnetic polarity,, do not install said poly-magnetic spare if between adjacent permanent magnets, neither install said veil yet, also be fine; In this case, the opposed facing surface portion ground of adjacent permanent is close together mutually, and makes between the said that part of surface that is close together mutually and have air gap.Oxygen-enriched air enters the link passage via said air gap, is extracted with this path.
The said various size of gaps of the present invention are not limit.Said air gap only may diminish to by two objects that are close together mutually because of the uneven small air gap that causes intrinsic on the object surface.On the other hand, make permanent magnet surface or veil surface or poly-magnetic spare surface contain some salient points or burr for forming the air gap of suitable size, also can designing artificially.
In the said various types of air gaps of the present invention position, certainly allow to install the pad spare that is used to support air gap, keeps size of gaps.Said pad spare also can have filter dirt function simultaneously concurrently.Said pad spare can also be made with magnetic conductive material, and such pad spare also has the function of adjusting air gap internal magnetic field distribution situation.
In the said air-magnetism separating device of the present invention, the quantity of the said link passage that is contained is not limit; In most application scenarios, require in said device, to contain simultaneously many said link passages; But for the little application scenario of throughput, can use small-sized device, the link number of channels that contained can be few in the device, for example, may be as few as the link passage that only contains, two, three or four.Certainly, the link number of channels that is contained in the small-sized device not necessarily just can only be a small number, and big quantity also is fine, and for example can adopt the mode of minification according to a certain percentage, constructs the link passage of the trumpet of big quantity in midget plant.In addition, the shape of cross section of said link passage is not limit.
Preamble is addressed, if the inlet channel of said link passage with the compressor that is used to carry oxygen-enriched air is communicated with, starts this compressor, just can export oxygen-enriched air from the outlet passageway of this compressor; Said permanent magnet bunch should be exposed to and to contain in the oxygen source air.The said compressor of the present invention refers to the machinery that is used to aspirate, pressurize, carry gas, and for example, air compressor, air blast, ventilation blower, vavuum pump, air pump or the like all are compressors.Containing the air-magnetism separating device that is useful on the compressor of carrying oxygen-enriched air is a kind of device form of the said air-magnetism separating device of the present invention.
No matter whether the said air-magnetism separating device of the present invention contain the compressor that is used to carry oxygen-enriched air of special configuration, said permanent magnet bunch directly can be placed in the containing in the oxygen source air of nature circulation; Even if said contain the oxygen source air be in the nature flow rate approach zero like inactive state, because the factor of concentration difference diffusion, contain the airborne oxygen molecule of oxygen source and still can be continuously move to the direction of said permanent magnet bunch, with remedy around the said permanent magnet bunch because of being drawn the oxygen content on the low side that causes.But, in order to give full play to the oxygen delivery capacity of said air-magnetism separating device, preferably said many permanent magnets that contains hole are installed in the container, said container is the container that contains three kinds of gas passages, said three kinds of gas passages are fresh air input channels, oxygen-enriched air output channel and nitrogen-rich air output channel, said link passage is communicated with the said oxygen-enriched air output channel of said container, under said circumstances, if the said fresh air input channel that makes said container is communicated with the outlet passageway of the compressor that is used to carry fresh air, start this compressor, just can order about and contain the oxygen source air and skim over said permanent magnet bunch with the flow set and flow velocity; The another kind of driving contains the embodiment that the oxygen source air flows and skims over said permanent magnet bunch, and being the said nitrogen-rich air output channel that makes said container is communicated with the inlet channel of the compressor that is used to carry nitrogen-rich air.By the nitrogen-rich air of the said nitrogen-rich air output channel output of said container or perhaps the air of anoxic, can be according to the requirement collection or the emptying of using.
