Description
Technical field
The present invention relates to a kind of ultramicro air bubble apparatus and dual-circulation ultramicro air bubble diffusion system.Ultramicro air bubble apparatus is kept the vital movement of biologic chain in the water body by the mode oxygenation in water body with the ultra micro small bubbles, thereby can be widely used in multiple industrial sewage processing and city domestic sewage treatment system; And the air bubble diffusion system that utilizes the ultra micro small bubbles more can make airborne oxygen have adequate time to contact with water body with bigger contact area, thereby administer rich nitrogen sewage efficiently, but broader applications are in administering the rich polluted by nitrogen of more and more serious water body such as China lake, pond, reservoir, rivers, coastal waters.
Background technology
At present, the device that produces micro-bubble in water has multiple structure, for example many micropores sebific duct.But it is the above bubble of 1-2mm that this aeration tube can only produce mean diameter, and the probability that produces 0.1mm magnitude bubble is very little, that is to say to produce the following ultramicro air bubble of 0.1mm magnitude hardly.Reason is: even if the hole of 0.1mm size is arranged on the sebific duct, it has produced the bubble of 0.1mm to suppose beginning, bubble is not walked, because surface tension is not left sebific duct, must wait until that bubble rises and when buoyancy is enough to overcome adsorptive power, just leave greatly, at this moment, bubble has been grown up and has been arrived more than several millimeters at least 1.The similar tubule of this reason can only blow out big lather.Here it is also occur up to now can be a large amount of (almost 100%) produce the reason of ultra micro small bubbles device.Therefore, in water, produce less than 1mm even are very difficult things less than the ultra micro small bubbles of 0.1mm.Under the situation of equal volume, bubble is big more, and the contact area with water in water is more little, in water body the residence time shorter, thereby just low more to the ability of water oxygenation, it is also just poor more to administer the effect of polluting.
Usually the air bubble diffusion system that adopts is, lay the pipeline that a row can emit bubble at the bottom, these pipelines all link to each other with a main pipe line, and main pipe line links to each other with air compressor again, charge into pressurized air by air compressor in pipeline, a plurality of conduit arrangements become piping manifold.Pipeline is made up of rubber hose or plastics tubing, and micropore is arranged on the tube wall, and at the micro-bubble that can produce under the best situation about mean diameter 1-2mm, a large amount of rising bubbles can produce the air curtain as wall in water body.
The 1mm magnitude small bubbles that such air bubble diffusion system produces at most, inadequately little, the residence time in water falls short of, and rises and overflows the water surface rapidly and be not enough to play effect to the abundant oxygenation of water at the water body cathetus.It is still undesirable to handle the effect of polluting.
In addition, for bigger sewage work or be called as the device of quick-fried gas, normally adopt the bubble that produces about the 10cm diameter, the next door in the bubble pond of its magnificence, and discharging many of up to a hundred kilowatts of gas blowers.In this case, it is fast that bubble overflows speed and little with the contact area of water because bubble is big, and it is high therefore to handle the pollution power consumption, and oxygen-transfer efficiency is very low.
Summary of the invention
In order to address the above problem, it (is that flow velocity is bigger that the present inventor utilizes the Bernoulli principle, pressure is littler) invented and trial-produceed successfully the ultramicro air bubble apparatus that several (seeing embodiment) produces ultra micro small bubbles (it is the ultra micro small bubbles less than the bubble of 0.1mm magnitude that the present invention defines diameter), this device comprises a tracheae and a water pipe, it is the opening of 0.1mm magnitude and following bubble that the diameter of generation is arranged on the tracheae, the water outlet of water pipe is positioned near the opening of tracheae, during work, be filled with pressurized air in the tracheae, the water pipe water pump, make water spray, impact the opening of tracheae from the posticum on the water pipe.
This design is even overcome the bubble of mentioning in the background technology less than 0.1mm of having produced, because surface tension is not left the problem of sebific duct yet.High pressure water from water pump sprays from pipe outlet, move by near the air its next door tracheae opening of negative pressure drive of Bai Nuli principle generation, air has just shifted out a bit just washed away, contains ultra micro small bubbles one by one in the water of whole water pipe one side outlet ejection.Like this, the ultra micro small bubbles are firm to be taken away one by one once the current that form by powerful, does not merge accumulation and becomes big chance, therefore obtains the little bubble of ultra micro one by one.
The present invention also proposes this body matter of a kind of dual-circulation ultramicro air bubble diffusion system on the basis of said apparatus, so that above-mentioned ultra micro small bubbles are diffused in the whole water body efficiently.This ultra micro small bubbles diffusion system comprises the piping manifold commonly used that is arranged in parallel that is laid on water bottom, be provided with ultramicro air bubble apparatus of the present invention between the pipeline of per two the adjacent generation bubbles of this piping manifold, the bubble that the bubble diameter that the pipeline of described piping manifold commonly used produces produces greater than described ultramicro air bubble apparatus, thereby cause the circulation of the different water body of intensity, two kinds unbalanced circulates in the relative stagnant zone that micro-bubble is caused at the bottom.
Further, described a plurality of ultramicro air bubble apparatus is to be arranged on a series of ultramicro air bubble piping manifolds parallel with described pipeline commonly used.
Further, piping manifold commonly used and ultramicro air bubble piping manifold link to each other with separately trunk pipe-line respectively, and the main line of using piping manifold always is connected with air compressor, and the main line of ultramicro air bubble piping manifold links to each other with water pump with air compressor.
Further, it is the air curtain of 1mm magnitude that the pipeline of described piping manifold commonly used produces diameter, and the ultramicro air bubble apparatus adjacent with it produces diameter 0.1mm magnitude or following ultra micro small bubbles curtain.Invent this purpose that can produce the 0.1mm ultramicro air bubble apparatus except the oxidation effect of above-mentioned increase bubble, main purpose " two circulation " as described below in order to bring up.
Below with reference to accompanying drawing 1 and Fig. 6-8, the principle of work of dual-circulation ultramicro air bubble diffusion system of the present invention is described.One of bicirculating core purpose of this patent is to cause ultra micro small bubbles to be still in zone in the water relatively above the B pipeline.
For to this explanation, illustrate with several supposition how this ultra micro small bubbles stagnant zone forms below.
The first, suppose only A pipeline work (the B pipeline is not worked).At this moment the A piping manifold causes O type circulation as shown in Figure 1 in water.
The second, suppose only B pipeline work (the A pipeline is not worked).At this moment the circulation that causes in water of B pipeline as shown in Figure 6.
Examine Fig. 1 and Fig. 6, can find that the water body flow direction that A manages, the B pipe causes is always opposite.This is the basic reason that causes the bubble relative dead zone as described below.
The 3rd, suppose that A, B pipeline work simultaneously, but supposition B pipeline changes into the same specification of A pipeline, at this moment A, B pipeline at the circulation that causes in the water shown in 7, flow to opposite current as seen from the figure mutually and form new O type circulation, the o type circulation of B, A top current each self-forming oneself under bubbles entrain owing to AB pipe specification is the same.
Now, the 3rd supposition stops: the B pipeline is changed into the ultramicro air bubble apparatus that this patent produces the ultra micro small bubbles, (the B pipeline only can produce the ultra micro small bubbles), at this moment circulation has just changed greatly, as shown in Figure 8: above the B pipeline, because the bubble that B group pipe produces in this patent very micro-bubble rises very slowly, should cause the water body of very slow rising to flow.But, mobile the meeting of water body that this very slow water body that makes progress flows but and causes when being descended above it by A circulation, two circulation that direction is opposite act on this zone, and strength is cancelled each other, thereby cause the relative immobilized of ultra micro small bubbles zone above B.
In this zone, the ultra micro small bubbles rise by water body attempt, and the upper edge distal part decline water body attempt of A circulation allows this water body descend, and the result is this regional extra small microbubble also do not descend (in fact, examine is to rise especially lentamente) of not rising.In other words the ultra micro small bubbles can have and rest on this zone (Here it is relatively immobilized implication) for a long time, thereby have increased the ability of oxygenation in the water widely.
Take all factors into consideration like this, this patent causes two kinds of circulation in water body:
The one, ro circulation (see figure 1), it is risen by the pipeline A driving bubbles entrain water body that can produce 1mm magnitude bubble, and then divides to both sides and decline (being r shape), makes a circle at last, and the formation water body flows and is.Pipeline A place (shown in the direction of arrow among Fig. 1) is got back in the circulation of shape at last again.Cause the circulation of macroscopical water body like this, visually it is called the ro circulation below this patent.
The 2nd, ri circulation (see figure 8), it is driven by the pipeline B that can produce 0.1mm magnitude bubble, above the B pipe relatively in the quiescent centre, water body flows to both sides along the r type to rising from the beginning of B pipe especially lentamente again, because a little less than the lifting force, be subjected to the A pipe and just be tending towards static after the downward circulation in this zone is suppressed, this patent is represented this relative immobilized zone with " i ", can circulate the slow circulation called after ri of B pipe top this patent invention below.
The ri circulation produces the ultra micro small bubbles that can stop for a long time in water body like this, the air curtain that the macroscopic view that cycles through ro rises drives each corner that water body O type moving handle ultra micro small bubbles take water body to, each part water body circulates many times under ro drives, thereby airborne oxygen is diffused in the whole water body.
Following two circulation abbreviation rori bubble binary cycle systems that this ro circulation and ri circulation are formed.
This circulation has adjacent overlapping areas, and the turbulent flow of overlapping region is brought the ultra micro small bubbles in ri stagnant zone limit into the ro circulation.Each corner of the water body that covers is taken the ultra micro small bubbles in the diffusion of similar like this room dust at last.
In order to obtain the maximum efficiency of oxygenation, the B pipe also can and discharge two groups or many groups.
Above-mentioned dual-circulation ultramicro air bubble diffusion system, the ultra micro small bubbles have increased the contact area of oxygen and water on the one hand, on the other hand, because two circulation of bubbles systems, cause the relative quiescent centre of superminiature bubble, allow bubble stay in for a long time in the water, in this zone, by the bubble of 0.1mm diameter, the general diameter 1mm of the time ratio that bubble contacts with water body bubble was grown more than 100 times in the life-span under the single loop situation.Therefore, increase substantially oxygen dissolved efficient and speed in water, simultaneously, also reached purpose of energy saving, when particularly administering big rivers and lakes pollution, can reduce the cost of investment and operation greatly.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described.At first, Fig. 2-the 5th, the sectional view of four embodiment of ultramicro air bubble apparatus of the present invention.As ultramicro air bubble apparatus among Fig. 2,1 is water pipe, and 2 is tracheae.Tubule 1 water pump at center, the about 0.6mm of external diameter, peripheral tracheae 2 connects air source, the about 0.8mm of internal diameter.High pressure water from water pump sprays from interior pipe tube head, the air that the negative pressure that is produced by the Bai Nuli principle drives its next door moves, contain ultra micro small bubbles one by one in the water of whole mouth of pipe ejection, just take away, merge accumulation and become big chance once the current that form by powerful.Therefore obtain the little bubble of ultra micro one by one.
After bubble entered in the water, along with the current macroscopic motion moves forward, bubble was more little, and the speed of rising is slower naturally in water, and (the similar dust of this reason descends very slow equally because of little at air) be not so see that almost bubble is in rising.Good design should make the bubble merging (one-tenth air pocket) that do not bump each other.
The ultramicro air bubble apparatus of above-mentioned several settings is made assembly, is combined into to be pressed together on the B pipeline, and a large amount of such assemblies is housed on the B pipeline of formation.
Fig. 4 and Fig. 5 are two kinds of devices in addition of ultramicro air bubble apparatus of the present invention.Fig. 4 has the bubble opening on the tracheae 2, water pipe 1 is arranged near the bubble opening, and water sprays from pipe outlet, impacts the ultra micro small bubbles that the bubble opening produces.Tracheae 2 among Fig. 5 and water pipe 1 all are the thicker pipelines of using always, cut out two bubble openings 4 and two water outlets 3 above them respectively, and each water outlet lays respectively near the corresponding bubble opening, impact the ultra micro small bubbles that each bubble opening produces.Like this, can cut out a series of such openings side by side on pipeline commonly used, the size of bubble opening and water pipe water outlet is about 0.1mm.Ultra micro small bubbles generation device shown in Figure 5 is convenient to mass production, therefore narrates as the representative of multiple ultramicro air bubble generation device in its elsewhere of this patent.
Based on above-mentioned ultramicro air bubble apparatus, dual-circulation ultramicro air bubble diffusion system of the present invention is provided with as follows, and referring to Fig. 9: it comprises the piping manifold A that can produce small bubbles and has the piping manifold B of ultra micro small bubbles device of the present invention.Charge into pressurized air in the A piping manifold among the figure (A1, A2, A3......), this pipeline is made up of rubber hose or plastics tubing, every about 10mm-20mm, there is a slit to cut the hole on the tube wall, can produce the micro-bubble about mean diameter 1-2mm, a large amount of rising bubbles can produce the air curtain as wall in water body.
B piping manifold (B1, B2, B3......) is formed for the ultramicro air bubble apparatus that is produced the ultra micro small bubbles by the present invention, be also referred to as the microbubble piping manifold, in fact each lateral in the B piping manifold is made up of the structure described in embodiment Fig. 2-Fig. 5, comprise two pipelines, a water pump, another root connects air compressor, and it can produce diameter is 0.1mm magnitude and following ultra micro small bubbles thereof.On the length direction of each B pipeline, be provided with a plurality of ultramicro air bubble apparatus of the present invention, they can be into assembly and are installed on the B pipeline, also can be a series of otch as shown in Figure 5 that are provided with on the B pipeline
Two groups of pipeline group are dressed up parallel piping manifold system, are placed on below the water surface, near the bottom of water, by trunk pipe-line and stationary installation system and device are coupled together, and A piping manifold and air compressor on the bank 5 link; The B piping manifold is except that linking with other air compression, and water pipe wherein also will link with water pump 6.Pipeline and water surface parallel to each other are equidistant.Pipeline can be very long, but will guarantee that the pressure reduction of the pressure difference of pipeline compressed air and high pressure water is quite little, with the bubble basically identical that guarantees that the pipeline each several part produces.After pipeline was started working, two groups of pipelines of A, B began to produce a large amount of bubbles.A large amount of bubbles rise in water, produce air curtain drive it above water body move upward.Like this, as the described principle of work of summary of the invention, B group ultra micro small bubbles form certain relative stagnant zone in water body, and the air curtain drive water body cyclic motion that A group macroscopic view rises takes the ultra micro small bubbles each corner of water body to, thereby airborne oxygen is diffused in the whole water body efficiently.
It is not as the CO2 in the carbonated drink so easy (CO2 forms carbonic acid, and easy and water mixes) that oxygen dissolves in water.Oxygen is difficult to be dissolved in the water, in the time of can only leaning against bubble surface oxygen and contact with water surface slowly molecular diffusion " molten " enter.This patent has adopted the dual-circulation ultramicro air bubble diffusion system of the B pipeline of ultra micro small bubbles devices just, has increased substantially oxygen dissolved efficient and speed, can obtain from following two aspects embodying:
First: can produce diameter at 0.1mm magnitude and following ultra micro small bubbles because the present invention produces the B pipe unit of ultra micro small bubbles.This ultra micro small bubbles are seldom valuable, find out from following table, bubble is little, bubble surface area increase at double under the same volume: if diameter is used as foundation area unit for the 1cm bubble area, diameter is the 0.1mm bubble surface area with being 100 times of diameter 1cm bubble surface area under the volume so; And diameter is about the bubble surface area of 0.01mm is 1000 times of diameter 1cm bubble.Concrete numerical value can be referring to following table 1
Table 1
| Bubble diameter (mm) 10 1 0.1 0.01 |
| Bubble surface area (mm 2) 314 3.14 0.0314 0.00314 A＝4πr 2 |
| Bubble volume (mm 3) 524 524×10 -3 524×10 -6 524×10 -9V＝4πr 3/3 |
| Small bubbles are full of 1cm 3The back bubble total area is 1 10 100 1000 1cm 3Multiple |
Second: from the bubble diffusion principle, owing to utilize Rori bubble binary cycle system shown in Figure 8, cause the relative quiescent centre of superminiature bubble, allow bubble stay in the water for a long time, in this zone, by the bubble of 0.1mm diameter, the general diameter 1mm of the time ratio that bubble contacts with water body bubble lifetime has been grown 100 times.
Comprehensive above-mentioned these two kinds of aspect factors, because this patent bubble diameter is little nearly 100 times, the oxygenation area is big nearly 100 times, simultaneously, the residence time has increased nearly 100-1000 again doubly in water, consider the factor of this two aspect, the oxygenation capacity of this patent unit volume air feedwater has improved greatly than generally speaking oxygenation capacity in the past, has increased the effect of administering the oxygenation of rich nitrogen sewage; Be energy-conservation on the other hand, under the situation of using certain energy (water pump and air compressor machine), improved the efficient of oxygenation, therefore, also reached purpose of energy saving, when particularly administering bigger rivers and lakes pollution, investment and running cost are reduced greatly.
It below is the application example of dual-circulation ultramicro air bubble diffusion system of the present invention
Application examples one: the rich polluted by nitrogen of lake, pond, reservoir, rivers is administered in the original place.
Utilize dual-circulation ultramicro air bubble diffusion system of the present invention fully oxygenation in the water body, just can efficiently promptly go up oxygen level in the water body.
Oxygen has been arranged in the water body, the eubiosis of the Nature returns to good native state rapidly: cause that by anoxic smelly anerobe is dead rapidly in the rich polluted by nitrogen water body, the substitute is aerobic bacteria (also cry and have a liking for the oxygen bacterium or have a liking for oxygen animalcule, aerobic microbiological), and because water body nitrogen phosphorus, organic content are high and nutritious, aerobic microbiological just begins a large amount of breedings.Aerobic microbiological can be nitrogen transformation an ammonia, is converted into nitrite anions then, is converted into nitrate radical (NO at last
3 -), phosphorus is changed into PO
4 -Here it is nitrogen phosphorus biochemical aerobic decomposition course under the aerobic bacteria effect that with it is food.
Be that nematode, mud worm, ciliate, wheel animalcule and other planktonic organisms of food begins a large amount of breedings simultaneously with microorganism and organism.
Again, next food chain such as crab, small lobsters, shrimp, silver carp and other various fish begin raised growth.
Be fish (as minnow) the beginning breeding in a large number of water flea and some drinking water algaes of food simultaneously with the algae, algae is one of basis of fish food chain.
Good pasture and water begin raised growth in the water body simultaneously, fish (as grass carp, bream etc.) the beginning raised growth of drinking water grass.
Bring back to life by such biologic chain, the nitrogen of rich polluted by nitrogen, phosphorus, organism finally are converted into fish, shrimp, crab.
Here it is utilizes this patent to recover the process that the eubiosis of the Nature is administered rich polluted by nitrogen water body as means in water body.
In warm season, in lake, reservoir, need etc. 1 month approximately, water quality will be better and better after setting up the good eubiosis, biological oxygen demand BOD (being Biology Oxygen Demands) can progressively lower, as long as diligently long-time, the water after process the present invention handles is better than the water quality of sewage work.In the governance process, device is simple, and current consumption is very little.The on-the-spot like this sewage of administering same volume on the spot, the investment operation reduces significantly.
Application examples two: the peculiar smell of eliminating water in the reservoir.
Set up the series connection of 2 water reservoirs earlier, each circulates oxygenation a couple of days with dual-circulation ultramicro air bubble diffusion system of the present invention for a long time at Chi Zhongxian, obtains nearly saturated oxygen solubleness, as long as eliminated nitrogen phosphorus and other organism, peculiar smell has just been eliminated.Water behind the elimination peculiar smell can be delivered to water factory and make the water source.This way is obviously good than adding pharmaceutical chemicals or fill methods such as chlorine in water.At least, can add less.
Application examples three: remove the ice sheet on the water surface in the winter time.
In the north, on the winter lake surface and in the reservoir a thick layer of ice is arranged, the time has four months approximately.Ice sheet has completely cut off oxygen fully, makes the blind area of water body deterioration, aquatic animals and plants death, and it has limited the quantity of subglacial aquatic animal greatly.It is very useful for water body resurrection in spring next year, a large amount of existence of aquatic products animals and plants to eliminate ice sheet, for water body oxygenation obvious effects is arranged also.
Way is to draw a long line with one group of A, B piping manifold edge and northwest wind vertical direction, puts dual-circulation ultramicro air bubble diffusion system of the present invention without big area, and several groups of pipes just can work, pipeline put into reservoir darker (can not contact the bottom) under water.
The a large amount of bubbles in pipeline ventilation back rise, and drive the higher water of water-bed temperature and upwards flow to ice sheet, cause local thawing of floating ice above it.After the thawing, there is a line of wide about 1-3 rice to become water in the air from the ice sheet of looking.Winter, strong wind was many, and ice face windward is bigger.At this moment, blowing hard if having at northwest monsoon, will progressively blow the established several meters wide water surface wide: blow afloat ripplet (also not being wave) on the water surface, ripplet drives the water surface and flows to wind the place ahead, constantly the ice of its front of impulsive motion.At last, on the ice face, will progressively draw back more and more long no ice formation, reach several kilometers.No ice formation is in case formation is having the wind sky just can not freeze again.When occurring, just understands the weather of not blowing up to many days regelation.But run into when freezing, can newly restart dual-circulation ultramicro air bubble diffusion system of the present invention, treat again the ice top blast to be opened when blow next time.The water surface is bigger, removes ice sheet more easily.Just remove the ice in main body waters with this way, this is enough to the biologies such as fishes and shrimps in the water.
What the method for this removing ice sheet was mainly leaned on is wind energy, and dual-circulation ultramicro air bubble diffusion system of the present invention has been the startup effect, removes the area of ice and sees wind-force size and time length, little with the degree relation of cold weather.In other words, also can remove ice sheet in the coldest coldest days of winter with this way.In Beijing, can remove the thick ice sheet of a nearly chi with this quadrat method.On big reservoir, can remove 60% area, clean-up time fraction of coverage about 80% approximately.Not so good for the Xiao Chi effect.
Application examples four: the sewage work that sets up high efficiency, low cost with dual-circulation ultramicro air bubble diffusion system of the present invention sets up the pond of several picture swimming pool sizes, dual-circulation ultramicro air bubble diffusion system of the present invention is installed respectively, the pond is together in series, water body respectively circulates about 10 days in three ponds, nitrogen phosphorus organism and mud are removed with the present invention in preceding two ponds, water outlet is at the middle part, pond, and organic nitrate, phosphoric acid salt, residual microorganism and suspended solids also should be eliminated in last pond.Thereby reach high-level water treatment.
Water after treatment looks that to look like natural river general.
