This device consists essentially of the oxygenous oxygen generator 2 by admission of air, with the membrane contactor 1 of the height enriched gaseous oxygen that contacts dissolved oxygen producer 2 to be provided by general's height enriched gaseous oxygen and water.
According to the present invention, oxygen generator 2 can use various conventional oxygen generator well known in the art.For example, the present invention can adopt adsorption scheme or film scheme to produce oxygen.Because adsorption scheme is used sorbent material, sorbent material can produce particle, therefore needs to remove the device of absorbent particles.But, according to the present invention, can be by being used for making oxygen dissolution come the particle of Filtration Adsorption agent in the mode of the membrane contactor 1 of water, thus do not need to provide separately the device of removing absorbent particles.Therefore, the present invention can adopt adsorption scheme without restriction.
Ultimate principle according to adsorption scheme, as shown in Figure 3, when the high compression air when being full of the adsorption tower of sorbent material, adsorption tower mainly adsorbs and has higher optionally composition, as nitrogen, and allow to have low optionally oxygen and be discharged into the outside by adsorption tower.This sorbent material comprises molecular sieve.As needs, can cooling compressor the air of compression to improve adsorptive power or to remove airborne aqueous vapor.In addition, cooling air is incorporated in two adsorption towers one, at that time, because the difference of the absorption property between nitrogen molecule and the oxygen molecule, the nitrogen that comprises in the adsorption tower absorption cooling air is prior to oxygen.When the sorbent material that provides in the adsorption tower was saturated by nitrogen molecule, electronic controls detected this saturated and opens solenoid valve, and pressurized gas is introduced in another adsorption tower like this.Simultaneously, to being carried out purifying treatment by the saturated adsorption tower of nitrogen, wherein, nitrogen discharges from sorbent material and is discharged into the outside by nitrogen adjustment valve 10, and adsorption tower can utilize once more like this.Therefore, can produce oxygen continuously by repeating above-mentioned steps.Above-mentioned steps can repeat with several seconds interval, and sorbent material repeatedly adsorbs and discharges nitrogen molecule like this.
According to an embodiment of the invention, except that adsorption scheme, can also use the film scheme to produce oxygen.The film that is adopted in the film scheme comprises porous-film or non-porous film, and can be divided into flat membranous type film and hollow fiber type film.
According to the ultimate principle of film scheme, oxygen is based on that difference by the osmotic pressure between the composition of the gaseous mixture of film produces.As shown in Figure 2, the pressurized air of introducing film is made up of all gases that comprises oxygen and nitrogen.This gaseous mixture contacts with a surface of film, and a kind of gaseous constituent of this gaseous mixture can optionally be passed through film so at least.This optionally the gaseous constituent by film must have and be higher than at least a also speed of the gaseous constituent by film not in this gaseous mixture.In addition, also must not pass through film with the speed that is lower than at least a gaseous constituent in this gaseous mixture by the gaseous constituent of film.Based on this principle, gaseous mixture can flow respectively along two flowing-paths, and wherein, flowing-path mainly contains the gaseous constituent by film, and another flowing-path mainly contains also not the gaseous constituent by film.Therefore, in order to separate this gaseous mixture suitably, film must be made by the material that has high selective permeability at concrete gaseous constituent.
In order optionally to separate and the concentrated gas mixture, under the preferable case, described film has unsymmetric structure, and wherein, this unsymmetric structure comprises the rete with compact surface and is arranged on the poroid carrier of the lower position of film.At concrete gaseous constituent in the gaseous mixture, selective permeability can change according to the quality of the compact surface of rete, and the flow velocity of isolated gaseous constituent can and form unsymmetric structure according to the thickness of rete and changes than the porosity of the porose carrier of lower part from gaseous mixture.For selective separation gaseous mixture efficiently, can not form that the aperture is 5 under defective and the preferable case at film surface
Or it is littler.In addition, in order to obtain higher gas permeability, if possible, rete must be prepared into thin thickness.This is because gas permeability and effective film thickness are inversely proportional to.And, minimize in order to make optionally the suffered resistance of gaseous constituent stream by rete, unsymmetric structure be preferably vesicular structure than lower part.For example, can use tubular fibre or flat film prepare unsymmetric structure than lower part.
By the oxygen of oxygen generator 2 as film or sorbent material generation, move to membrane contactor, oxygen contacts with water there, thus oxygen dissolution is in water.Thereby the structure according to membrane contactor 1 of the present invention allows liquid to flow to or outlet pipe by membrane contactor 1.At this moment, with the right position of water enriched gaseous oxygen (concentrated oxygen) is offered pipe by one, enriched gaseous oxygen is dissolved in the liquid thus.The oxygen that produces by oxygen generator 2 is introduced into and does not produce bubble by membrane contactor 1.Just, the oxygen by membrane contactor 1 is dissolved in liquid owing to oxygen diffusion, in water.The present invention is dissolved in oxygen in the water with molecular form by membrane contactor 1, thereby has improved the content of dissolved oxygen simply, and keeps dissolved oxygen for a long time.Especially, the present invention does not need conventional spraying equipment.And, need not improve the pressure of container or reduce the temperature of container.
When considering contact area and fluid velocity, under the preferable case, liquid flows to pipe by membrane contactor 1, rather than by membrane contactor 1 outlet pipe.In addition, if the length of membrane contactor 1 is long, the efficient of membrane contactor 1 can reduce, and therefore, membrane contactor 1 preferably has suitable length.Under the preferable case, membrane contactor 1 has waveform configuration to increase the surface-area that contacts with liquid.In addition, membrane contactor 1 or have vesicular structure perhaps has non-porous structure.For more suitably guiding gas diffusion, membrane contactor 1 preferably has non-porous structure.Can use tubular fibre or flat membrane prepare membrane contactor 1.In addition, the material that is used for preparing membrane contactor 1 comprises the material that is selected from the group of being made up of polysulfones, polysulfones matrix material, polypropylene, polyethylene, polyethersulfone, polyimide, teflon (Teflon), polysiloxane (silicon), tetrafluoroethylene and their mixture.
