Definitions
- the present invention relates to a device for generating and handling nanobubbles and, more particularly, to a device for generating microbubbles, nanobubbles and ultra-nanobubbles of desired sizes and a method of handling them in bulk solution.
- Nanobubbles are recognized as those gaseous cavities with diameters between 1 ⁇ m and 100nm.
- Ultra-nanobubbles are gaseous cavities with diameters below 100nm.
- MB microbubbles
- MNB micro-nanobubbles
- Patent Document 1 a method of forming NB, of size between 1 ⁇ m and 200nm is described, by applying physical irritation to MB contained in a liquid with electrical conductivity of 300 ⁇ S/cm, so that the MB contract abruptly to form NB.
- Patent Document 2 details a method for forming MNB, of size 10 ⁇ m-300nm, from an impregnated nano-particle.
- Patent Document 3 describes a method for generating and dissolving NB, of size from 50 ⁇ m to a few hundred nanometers, by applying a gas to the inside of a bamboo filter.
- Patent Document 4 a method for producing NB, of size of 10 2 nm, by mixing different amounts of water on different temperatures, is described.
- a NB generator device which can produce a fluid stream of bubbles with the aid of an oscillating wave feed pump.
- Microporous beads are used in a porous sleeve, and air and liquid are introduced into the sleeve. Nanobubbles are formed in the voids between the porous beads, and are then introduced into a liquid flowing parallel to the major axis of the porous sleeve.
- a low cost and quickly made generator to produce a NB-containing liquid is described in Patent Document 6.
- a fine-bubble-containing liquid is produced by introducing a gas into the MB generator and finer bubbles are produced by shearing the liquid and gas with an impeller in a second tank. Nanobubbles are prepared in such a way from the MB liquid passed into a third tank.
- the previously generated NB have been restricted to sizes between 1 ⁇ m and 100nm; or to MNB range (100nm-50 ⁇ m).
- the smallest claimed size in open literature is 50nm.
- NB adhere to adjacent surfaces of the NB reservoir instead of remaining in the bulk.
- UNB ⁇ 10nm
- the present invention produces NB that may also have dimensions smaller than 50nm; that is UNB. Because of their astonishing small size, UNB have potential for use in many industrial applications as well as in biological ones. For the latter case (e.g. human health), it is important that the NB be ingested.
- a device for producing bubbles in three stages at three different dimensions by using three different generators.
- generator 1 a liquid is mixed with pressurized oxygen or other gas to generate bubbles in the liquid.
- the bubbles produced at this stage progressively decay in G1 to the MB size range.
- Said MB liquid is then passed through generator 2 (G2) where NB are generated by passing the liquid through a macro-porous material.
- UNB are generated either statically or through rotational and/or vibrational forces; the NB produced in G2 are introduced into generator 3 (G3) which is a fractal pump.
- Said pump consists of a porous plug with a fractal roughness on the pore walls, and an oscillating piston.
- This pump works by utilizing the energy differences between Baxter-Cassie and Wenzel wetting states to produce UNB under high pressure.
- the porous plugs can rotate for more effective production of NB or UNB in the liquid, and the material from which they are made can be of various composition and pore size (e.g. porous glasses, porous gold, etc).
- a NB capture device in the best form of dietary powders such as: zeolite, medicinal activated charcoal, etc. This is achieved through the introduction, agitation and sedimentation of the powders in the stage-two NB reservoir. The NB will preferentially adsorb on the particle walls. The NB-attached powder is then removed from the NB generation tank and provided for storage, handling, transport or even human consumption.
- NB of specific size can be produced by design for the first time.
- the novel methodology for capturing and extracting the NB described herein implies that said NB can be ingested by humans in a human-friendly and beneficial means.
- Fig. 1 is a schematic illustrating the main components of the Nanobubble Generating Device, and their interconnection.
- the system consists of three generators connected in series. Gas and a liquid are introduced to G1 [100] to produce a MB-containing liquid.
- the liquid is fed to G2 [200] where it passes through a porous material [201], generating MNB. These are stored in G2-Tank [400] and can be collected for various applications, even for human ingestion by introducing a dietary powder into G2-Tank [400].
- the MNB-containing liquid from this tank can be circulated back to G1 or pumped to G3 [300].
- the liquid is compressed at 150bar and oscillated back and forth through a fractal porous material [301] to generate an UNB-containing liquid.
- This can be collected in Tank 3 [500], or deposited on a hydrophobic surface such as Highly Ordered Pyrolytic Graphite (HOPG) [501].
- HOPG Highly Ordered Pyrolytic Graphite
- G1 [100] consists of rotary pump 1 [101] and rotary pump 2 [102] connected in series.
- Gas and a liquid enter a mixer [103] through a capillary tube [104] from a gas tank.
- Two check valves [105] ensure the flow is one directional.
- the MB-containing liquid passes through pump 1 and then pump 2, then into G2 [200] pre chamber [202] shown in Fig.3 .
- Said generator contains a diaphragm assembly [203] for compressing the MB-containing liquid and a fan [204] for stirring the MB-containing liquid.
- the pre chamber [202] is pressurized at 30 to 40bar to ensure permeability of the MB-containing liquid through the porous material [201].
- Said porous material can be rotated by switching on the DC motor [205], which in turn rotates the two rollers [207], [208], a belt [206] and the porous material.
- the MNB are generated as the liquid passes through the porous material and are collected in G2-Tank [400] shown in detail in Fig. 5 .
- a bypass system can be used to return the MNB-containing liquid back to G1 [100].
- said MNB-containing liquid can be pumped into G3 [300] shown in detail in Fig. 4 .
- the high-pressure chamber [307] in G3 is sealed and pressurized to 150bar via a piston [306] which oscillates back and forth in both directions to pump and pull the MNB-containing liquid through the fractal porous material [301].
- suction from G2-Tank [400] occurs to fill the high-pressure chamber, while on the forward movement the liquid is extruded at his pressure through the fractal porous material [301].
- a check valve [308] prevents the liquid from returning back to G2.
- the movement of the piston is achieved either by mechanical cam or by automatic hydraulic system.
- the porous material can be rotated by a motor [302], two rollers [303], [304] and a belt [305].
- the generated UNB-containing liquid is collected in G3-Tank [500]
- the MNB produced by G2 accumulates in G2-Tank [400] which is shown in detail in Fig 5 .
- a dietary powder such as natural zeolite of high purity, medicinal activated charcoal, etc., is inserted through a funnel [401] in the reservoir.
- the mixture of MNB-containing liquid and powder is stirred by a rotating stirrer [403] driven by a DC motor [402].
- the MNB or NB attach onto the surface of the powder. After a short time, the stirring is stopped, and the mixture is allowed to settle.
- the sediment can be collected from G2-Tank [400]. It is also possible to capture UNB generated by G3 [300] in a G3-Tank [500] or onto a hydrophobic surface such as Highly Ordered Pyrolythic Graphite (HOPG) surface [501] positioned above said tank.
- HOPG Highly Ordered Pyrolythic Graphite
- Fig.6 shows a small-angle X-ray scattering spectrum of a sample containing oxygen NB in water.
- a blank water sample is presented too.
- the detector was a 2D X-ray imaging system based on a gas-filled multi-wire proportional counter coupled to an artificial delay line. Capillary tubes of diameter equal to 1mm are used as liquid sample holders.
