Description

Technical Field

[0001] The invention belongs to the technical field of purification of domestic sewage and various industrial wastewaters. Background Art

[0002] In recent years, my country's urban domestic sewage and industrial wastewater treatment capacity has developed rapidly, and many sewage treatment plants have been established or will be established in various places. The digestion and disposal of the large amount of sludge produced by these sewage plants has naturally become a major problem in the field of environment. With the large increase in sewage treatment capacity and sewage treatment volume, the discharge of sludge will inevitably increase significantly. The daily sludge volume produced by a general medium-sized sewage plant is about 20,000 tons (water content 70% to 80%). The treatment of sludge is also very troublesome. At present, the treatment methods at home and abroad are: 1. Burial, 2. Reclamation, 3. Incineration, 4. Agricultural use, 5. Burning bricks and tiles. Because the sludge contains heavy metals, pathogens, parasite eggs, etc., the above sludge treatment methods are not appropriate, and the consequences are very serious. The only way is to achieve the maximum sludge reduction.

[0003] So far, all the aeration and oxygenation equipment for domestic and foreign sewage treatment are basically high-power blowers in various blower rooms, which send air to the sewage pool through large ventilation ducts, and then use various types of microporous aeration heads, such as microporous aeration discs and microporous aeration tubes, for aeration and oxygenation. In addition, there are Ober oxidation ditches, inverted umbrella-shaped surface aerators, submersible jet aerators, and rotary disc surface aerators for aeration and oxygenation. All of the above aeration and oxygenation equipment generally have problems such as high energy consumption, low oxygen transfer rate, and large sludge discharge.

[0004] With the continuous development of the national and world economy, environmental issues have become more and more the primary problem restricting the economy and people's health. Among them, the rational and effective use of water resources is particularly important. The treatment and reuse of sewage can solve the shortage of water resources and reduce pollution. The treatment of sewage is increasingly valued by the state and enterprises. 70% to 80% of the energy consumption of sewage treatment plants is due to aerators. The existing microporous aeration, rotary disc aeration, and inverted umbrella aeration can no longer reduce energy consumption due to design defects.

[0005] There are a large number of microorganisms in sewage treatment, which have the ability to digest and degrade complex organic matter and some types of inorganic matter in sewage, and transform these substances into simple non-toxic and harmless substances. Practice has proved that the use of microorganisms to treat harmful pollutants in sewage has the advantages of low investment, high efficiency, simple operation, stable operation, low cost, good effluent quality, fast sludge settling speed, and can be used as fertilizer. Among the biological treatment methods, the activated sludge method has an extremely important position because of its advantages of basically no odor, short treatment time, and high treatment growth rate. In this method, aeration is indispensable. Its function is to supply sufficient oxygen and stir the mixed liquid to keep the activated sludge in a suspended state so that it can be fully contacted and mixed with the wastewater for degradation and oxidation. At the same time, the floccules in the sludge are also suspended in the sewage. Stirring and magnetic treatment can provide a large number of tiny bubbles. There is a large surface tension at the interface between these small bubbles and water, so a layer of suspended matter is adsorbed on the surface of the small bubbles to form hollow balls floating on the water surface. This is the role of flotation, which promotes the rapid precipitation of sludge and reduces the discharge of sludge.

[0006] At present, the commonly used aeration methods at home and abroad include blast aeration, mechanical stirring and jet aeration, but they generally have the disadvantages of low oxygenation capacity and oxygen utilization, uneven air distribution, frequent blockage or bursting, and very difficult maintenance and replacement, and their power efficiency is even lower. So far, the research and development and manufacturing processes of all aeration and oxygenation devices at home and abroad are primitive, all of which are simple and direct mechanical methods to send ordinary air into the water, so that the oxygen in the air is naturally mixed into the water, so the oxygen utilization rate and mechanical power efficiency are very low.

[0007] The prior art similar to the present invention is the invention patent with patent number 201410031267.7, the inventor is Guan Pinsan, the patent name is "Purification and oxygen-enhancing flotation aeration device", which adopts an ultra-short axis, a flying knife-shaped strong push flow, and a fan stores the air supply bin without vortex flow to adjust the air supply volume, and then a resistance-free air duct sends a large amount of oxygen-rich high-pressure air into the air supply bin.

[0008] There is also a technology similar to the present invention, patent application number 201510697753.7, invention name "high gradient magnetic field oxygen gathering and nitrogen removal strong oxidation bidirectional push flow aerator", application date: October 23, 2015, inventor: Guan Pinsan. Its structure includes a square bearing platform plate, a protective cover, a high-pressure fan, an oxygen gathering and nitrogen removal device installed on the top, a ball-end cylindrical float and two spherical floats under the square bearing platform plate, an air intake optimization diversion tee, a double-end output shaft submersible motor, an extremely short hollow shaft, etc.

[0009] There is another technology similar to the present invention, patent application number: CN201610101367.1, invention name "Screw rod booster multi-directional push flow aerator", application date: February 24, 2016, inventor: Guan Pinsan. Its main structure is a spiral magnetic circuit oxygen-enriched nitrogen drive device, which is just a rare earth permanent magnetic ring with axial perforation in the middle, with opposite poles installed on both sides of a non-magnetic metal narrow strip, and then bent into a spiral shape, so that all N and S poles of the magnetic circuit are in a horizontal state.

[0010] In 1850, William Thomson exchanged views with Faraday on the issue of diamagnets for many times. In his letter to Faraday on June 19, he used diagrams to explain the difference between paramagnets and diamagnets. He drew a paramagnetic ball and a diamagnetic ball in a uniform magnetic field. The magnetic lines of force densely passed through the paramagnetic ball, but the magnetic lines of force through the diamagnetic ball were relatively sparse. Faraday analyzed the ability of matter to conduct magnetism based on Thomson's diagram. He increasingly realized that magnetic lines of force were not inherent in matter, and objects could not generate magnetic lines of force. They could only change the direction and density of magnetic lines of force distributed in space. In 1851, he published "On the Conductivity of Magnetism and Diamagnetism in Objects", and then proposed the principle of magnetic conductivity of matter in the paper "Magnetic Conducting Power" in the 26th issue of "Electrical Experimental Research", unifying paramagnets and diamagnets. The so-called magnetic permeability principle means that different substances have different magnetic permeabilities. Paramagnets allow more magnetic lines of force in space to pass through them, while diamagnets repel magnetic lines of force. According to this principle, paramagnets move to areas with higher magnetic line density, while diamagnets move to areas with lower magnetic line density. In this way, two paramagnetic balls in a magnetic field will repel each other because the magnetic line density in the area between the two balls is lower than that in the area outside the two balls; two diamagnetic balls in a magnetic field will also repel each other because the magnetic line density in the area between the two balls is higher than that in the area outside the two balls; but a diamagnetic ball and a paramagnetic ball will attract each other.

[0011] Based on the Faraday magnetic conductivity principle and the difference between the magnetic properties of oxygen and nitrogen, the present invention creatively designs a ball ring longitude and latitude magnetic circuit oxygen gathering dynamic activated oxygen aeration and oxygenation machine. Oxygen-enriched air with activated oxygen is prepared from the air, and is strongly sucked and pushed by a high-end high-pressure blower, and then forced into the magnetically treated sewage through centripetal pressurization, centrifugal pressurization and negative pressure technologies, thereby achieving the purpose of highly efficient oxygenation of various types of water. The machine can be widely used in various types of industrial and urban domestic sewage treatment, aquaculture, and the management of rivers, lakes and reservoirs. Its technical principle is as follows.

[0012] 1. Faraday's magnetic conductivity principle

[0013] According to Faraday's magnetic conductivity principle, the distribution state of the earth's magnetic field and the distribution state of the earth's magnetic field lines and the distribution state of the earth's longitude and latitude, the present invention discloses a "spherical ring longitude and latitude magnetic circuit oxygen gathering dynamic activated oxygen aeration oxygenator".

[0014] The molecular structures of nitrogen and oxygen are 1S 2 2S 2 2P 3 and 1S 2 2S 2 2P 4 Its properties are mainly determined by the L main layer (also called the 2 main layer, which includes 2 S 2 P The distribution and movement of electrons in each molecular orbital of the nitrogen molecule (sublayer). The orbital energy level diagram of nitrogen molecules shows that all electrons in each orbit form electron pairs with opposite spins. The JIP orbital energy is lower than the 6P orbital energy. The positive and negative charge centers overlap, and it is a non-polar molecule that is difficult to magnetize and very stable. O2 has two p electrons that occupy the antibonding orbital with higher energy, which produces molecular circulation. Magnetism is an inevitable attribute of it. However, N2 molecules do not have the conditions to produce magnetism and do not show magnetism. The two p electrons in the antibonding orbital of the O2 molecule have higher energy and are very unstable. Under the action of an external electric field or magnetic field, the displacement of the positive and negative charge centers of the O2 molecule itself is not only increased, but also the orientation of the entire O2 medium is polarized, that is, the magnetic susceptibility of oxygen X m 1.9×10 -6 , and the magnetic susceptibility of nitrogen is X m 0.013×10 -6 The difference between the two is about 150 times. As the temperature decreases, the magnetic susceptibility of oxygen will gradually increase. At -183℃, the magnetic susceptibility X m Will reach 1520×10 -6 , it will be more easily attracted by the magnetic field.

[0015] The main components of air are oxygen and nitrogen, which account for 21% and 78% of the volume respectively. If the difference in the magnetic properties of oxygen and nitrogen can be used, oxygen-enriched air with a higher oxygen concentration than the original one can be produced from the air. The oxygen-enriched activated aeration aerator is the third time that the inventor has creatively applied this principle. It uses high-energy rare earth permanent magnetic materials to enrich oxygen from the air, and after activation, it fully combines with magnetized sewage to increase the ability of sewage to dissolve oxygen by about 25%. It has set a precedent for water-gas synthesis technology in aerators and is the first in the history of aeration and oxygenation in the world to completely get rid of the energy-consuming and expensive bulky equipment such as gas supply pipeline networks and aeration heads.

[0016] 2. Magnetic treatment of water

[0017] Generally speaking, the special properties and effects of magnetized water can be considered to be some changes in the water structure caused by magnetization. Due to the structural changes, some of its properties have also changed, thus producing various effects, thus affecting the formation of crystal centers and the precipitation rate. The magnetic hydrogen bond destruction model theory believes that the binding energy of water molecules (about 10eV) is higher, much greater than the static magnetic energy of water (10 3 GS: about 10 -11 eV) and magnetoelectric effect energy, but the Lorentz force energy may be close to the hydrogen bond between water molecules (about 0.2eV), so it can affect the H-bond structure and even destroy the H-bond. This can change the structure of liquid water and affect its properties, thus producing various magnetic water effects. Summary of the invention

[0018] At present, more than 95% of the purification treatment of urban domestic sewage and various industrial wastewater in the world is treated by biological methods, which is inseparable from aeration, plug flow, mixing, flotation and sedimentation. Common equipment includes large centrifugal blowers, large Roots blowers and large machine rooms. The diameter of the air inlet pipe is 1200mm, the total length is 300m~500m cast iron ventilation pipes and aeration pipe networks, tens of thousands of aeration heads, aeration plates or aeration tubes, etc., all use microporous aeration! The microporous aeration plates or microporous aeration tubes used in the sewage field often have a large number of micropores blocked by sludge, resulting in insufficient oxygen supply. At this time, increasing the air supply can only increase the power consumption of the blower. The more serious consequence is that a large number of aeration heads will often be blown up after the blower pressure increases. In this way, there is only the need to discharge the sewage, clean the sludge, and replace the aeration plates or aeration tubes. These existing equipments require large construction investments, high operating costs, and are difficult to maintain. In fact, it is particularly difficult to achieve energy conservation (saving electricity) and emission reduction (reducing sludge emissions). This is all due to the poor, primitive and unreasonable principle structure and design concept of the above equipment.

[0019] The technical problem to be solved by the present invention is to improve the above-mentioned deficiencies in the technical field, so that the equipment technology of aeration, oxygenation, flow, stirring, flotation and sedimentation for biological purification of sewage can better achieve the indicators of energy conservation and emission reduction.

[0020] In order to solve the above problems, the present invention is based on physics, with magnetism, atomic and molecular physics, fluid mechanics, aerodynamics, etc. as the main factors, and fully studies water, sludge, oxygen, nitrogen, etc. in the air. Focusing on the oxygen (O2), water (H2O) and sludge and excess nitrogen involved in the present invention, we fully study and understand their properties, and develop and create a "spherical ring longitude and latitude magnetic circuit oxygen aggregation dynamically activated oxygen aeration oxygenator" according to new concepts.

[0021] 1. Magnetic properties of oxygen and nitrogen

[0022] Through the measurement of the magnetism of a large number of substances, three types of magnetic substances were discovered: "diamagnetic", "paramagnetic" and "ferromagnetic". Faraday proposed the "magnetic conductivity" through "electrical experimental research". The so-called magnetic conductivity principle - different substances have different magnetic permeabilities: paramagnetic substances allow more magnetic lines of force in space to pass through themselves, while diamagnetic substances repel magnetic lines of force. According to this principle, paramagnetic substances move to areas with higher density of magnetic lines of force, and diamagnetic substances move to areas with lower density of magnetic lines of force.

[0023] Magnetic susceptibility of oxygen O2X m =1.9×10 -6 Magnetic Susceptibility of Nitrogen N2X m =0.013×10 -6

[0024]

[0025] It can be seen that the magnetic susceptibility of oxygen is much higher than that of nitrogen, reaching 146.154 times. Therefore, oxygen O2 is a paramagnetic substance and has magnetotaxis, that is, it can be attracted by magnetism. Nitrogen N2 is a diamagnetic substance and is repelled by magnetism. Therefore, the present invention creates an oxygen gathering device and an oxygen activation device based on the difference in magnetic properties between oxygen and nitrogen.

[0026] 2. Physical properties of oxygen and nitrogen

[0027] The specific gravity of oxygen is 1.439 g / l, and the specific gravity of nitrogen is 1.25 g / l. The specific gravity of oxygen is 1.151 times that of nitrogen.

[0028] 3. Chemical properties of oxygen and nitrogen

[0029] Oxygen is a very active element. According to the molecular atomic structure of oxygen, the present invention uses a magnetic acceleration method to treat oxygen, that is, to give gyromagnetic acceleration to the fast-moving oxygen O2, so that the orbit of the outermost electron of the nucleus is slightly offset, which promotes oxygen to be more active.

[0030] 4. Physical and chemical properties of water

[0031] Water is composed of two hydrogen atoms connected by hydrogen bonds to form water molecules of hydrogen H2 and oxygen O. Its physical and chemical properties mainly depend on hydrogen bonds. Through appropriate magnetic treatment, the hydrogen bonds can be deformed, the surface tension of water increases, and its oxygen dissolving capacity is enhanced.

[0032] The present invention aims to solve the problems of the design principle and structure of aeration, oxygenation, air flotation and push flow technology equipment in the field of purification of various industrial wastewater and domestic sewage. The sewage involved includes water, a large amount of sediment, various fiber suspensions, oil and viscous impurities, harmful organic matter and microorganisms, and other heavy metals and ionic substances such as iron, calcium and magnesium.

[0039] In order to push and blow up the sludge deposited and accumulated under the ball-ring longitude and latitude magnetic circuit oxygen-gathering dynamically activated oxygen aeration and oxygen-enhancing device of the present invention, and then push it to a distant place by cyclonic diffusion, a small submersible motor 49 is installed under the plug flow aeration device.

[0041] The invention relates to a biological method for enriching paramagnetic oxygen in the air by a ball ring longitude and latitude magnetic circuit in a sewage deep purification process, and activating the enriched oxygen by a dynamic magnetic circuit with high-speed rotation of superimposed magnetic poles of the same polarity, and then sending the air containing enriched and activated oxygen to a sewage pool through the negative pressure and high-pressure suction effect of the invention, and fully crushing the air bubbles by air crushing blades at the moment when water and gas are just mixed, so that the air bubbles become very small, and at the same time, the mixture of these oxygen-activated oxygen-enriched air small bubbles and sewage follows a parabolic route, especially the actual walking trajectory of the activated oxygen-enriched air bubbles when running on the parabolic route is a spiral walking path, the oxygen in these activated oxygen-enriched air bubbles has a stronger affinity with the sewage polarized by the magnetic effect, and is easier to dissolve into water, so the efficiency of transferring these activated oxygen-enriched air into water is further improved. At the same time, the present invention can make small bubbles containing activated oxygen run in the sewage along a parabolic path in a spiral trajectory, so that the trajectory of the bubbles running in the water is very long, and the small bubbles stay in the sewage for a longer time, so the oxygen transfer rate of the present invention far exceeds the oxygen transfer rate of the traditional microporous aeration oxygenator.

[0042] Since the present invention distributes multi-directional magnetic lines of force inside and outside the entire buckled spherical wall, the magnetic space for enriching oxygen is expanded, the effect of enriching oxygen is improved, and the oxygen in the air can be enriched; the oxygen activation device can activate oxygen, making the physical and chemical properties of oxygen more active. In this way, it can not only improve the affinity of oxygen and water, but also play a strong oxidizing role on sludge, especially on calcium, magnesium, aluminum, iron and other ions in water, so that the ions in water are strongly oxidized into oxides and precipitated. In addition, when the mixture of water vapor and sludge is pushed by force, it must pass through the strong magnetic field on the front and back sides of the guide plate when passing through the guide plate. At this time, the oxygen-enriched air, water and sludge that activate oxygen encounter magnetic lines of force perpendicular to them in front of their flow direction. Under the influence of the magnetic effect, the loose sludge will produce agglomeration. In this way, the sludge sedimentation speed is accelerated, and the sedimentation speed can be increased by 50%. Due to the small bubbles in the sewage, the surface tension of the water at the air-water interface increases, and the small bubbles begin to float to the surface of the water. The small bubbles absorb a large amount of grease and viscous floccules in the sewage, and the suspended fibers are absorbed and wrapped on the surface of the small bubbles and float to the water surface. These floating objects can be mixed with charcoal to burn the boiler together, so the present invention can save more than one-third of electricity and reduce sludge discharge by about 35% under the same conditions compared with traditional equipment such as traditional microporous aeration. The present invention does not require large-scale basic construction in terms of application and installation, and the installation is extremely simple and convenient. It does not require a machine room, let alone a pipeline network, which greatly saves the investment in one-time construction. The equipment is stable in normal operation and simple to maintain.

A considerable part of the magnetic lines of force of these magnetic circuits installed on the inner wall of the large sphere penetrates the sphere wall of non-magnetic carbon fiber material.

[0063] The oxygen gathering and nitrogen removal device and the dynamic oxygen activation device of the present invention work by floating on the water surface, so three buoys are evenly installed at an angle of 120° around the triangular or circular load-bearing chassis 50 . Figure 1 In the figure, 55 is a cylindrical flat-bottomed inclined-top buoy; 56 is a buoy reinforcement device, which is an equilateral triangle or circular connection reinforcement device installed at the center of the highest side wall line of the buoy side; 57 is the buoy center axis of the cylindrical flat-bottomed inclined-top buoy; 54 is a tubular nut, which is firmly welded to the triangular or circular load-bearing chassis 50. The buoy reinforcement device 56 is welded at the center of the highest side wall line of the cylindrical flat-bottomed inclined-top buoy 55, and then a longer screw rod 62m is welded at the center of the outer side of the buoy reinforcement device 56, and a locking positioning screw nut 62w is provided. The screw rod 62m is screwed into the matching tubular nut 54 to an appropriate depth, and is tightened and locked with the locking positioning screw nut 62w. In this way, the distance and angle between the center axis 57 of each buoy and the center axis 73 of the whole machine of the present invention can be adjusted by the buoy reinforcement device 56, the screw rod 62m, and the tubular nut 54. 73 passes through the central axis of the upper and lower poles of the ball formed by buckling the upper hemispherical cover 1 and the lower hemispherical cover 2.

[0064] like Figure 1 The oxygen-enriched air after oxygen collection and nitrogen removal inside and outside the sphere formed by the upper hemispherical cover 1 and the lower hemispherical cover 2 enters the sphere from the air inlet 19 along the air flow direction 76, passes through the smooth air path of the oxygen-enriched activated air in the cylinder 5 of the oxygen activation device, that is, the empty cylinder 23 is strongly sucked by the high-end high-pressure fan 20, and then is sent to the air storage bin 41 through the three-way or four-way 25 of the pipeline and the pipeline 24 leading to the air storage bin. These oxygen-enriched activated air is subjected to centripetal supercharging by the oblique centripetal supercharging air inlet 30 on the high-speed rotating hollow shaft in the air storage bin 41, and is strongly sucked by the negative pressure generated by the strong pushing flow of the propeller blades 33 in front of the submersible motor 31, so that the activated oxygen-enriched air is ejected into the water at a very high pressure. The stirring and crushing blades 37 of the oxygen-enriched air installed at the water-gas contact interface can fully crush the activated oxygen-enriched air into very small bubbles in the water. The small bubbles pushed and the swirl of water and sludge run along a parabolic route after being guided by the bird-wing-shaped magnetic guide plate 34. However, the small bubbles have the smallest mass, so the running trajectory 38 of the small bubbles in the water-gas mixture is a spiral line, and the overall running direction is a parabola, as shown in FIG. Figure 1 The water-gas mixture small bubble running track 38. The bird-wing shaped magnetic guide plate 34 is equipped with a guide plate rare earth permanent magnet ring 35, and the bird-wing shaped magnetic guide plate 34 is installed around the front of the stirring and crushing blade 37 of the oxygen-enriched air, and can adjust the three-dimensional angle and direction.

The micromotor rare earth permanent magnet disk 44 is mounted on the driving micromotor output shaft 43. When the driving micromotor 42 rotates, the micromotor rare earth permanent magnet disk 44 and the central shaft rare earth permanent magnet ring 6 mounted on the central shaft 9 are magnetically coupled to each other, and the central shaft 9 can be driven to rotate at a high speed.

[0066] Example 2 Structure of oxygen concentration and nitrogen removal device

[0067] Based on Example 1, Figure 2 , 3 4 illustrates the structure of the ball ring longitude and latitude magnetic circuit oxygen gathering and nitrogen removal device of the present invention.

[0068] The structure of the oxygen gathering and nitrogen removal device mainly includes: 13 is an arc-shaped warp magnetic circuit ring, 14 is a circular weft magnetic circuit ring, 26 is a plum blossom positioning plate, 58 is a basic magnetic circuit component, 28 is a twisted warp and weft magnetic circuit component, and 78 is a warp and weft rare earth permanent magnet ring.

[0069] The oxygen gathering and nitrogen removal device is a sphere formed by fastening the upper and lower hemispherical covers together, and the arc-shaped warp magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14 are installed close to the inner wall of the sphere. Because the two hemispheres are made of non-magnetic stainless steel or carbon fiber, the magnetic circuits in the warp direction and the latitude direction of the sphere, the magnetic lines of force of these magnetic fields are directed upward, downward, left, right and in all angles, and the radiated magnetic lines of force are distributed in most of the space near the inner wall of the sphere; at the same time, a considerable part of them are radiated outside the sphere wall, that is, the magnetic field 50mm to 60mm near the outer surface of the sphere. Therefore, the oxygen content in the air layer about 50mm on the outer surface of the sphere wall is slightly higher than the oxygen content in the space outside it. This is the difference in the magnetic properties of oxygen and nitrogen in the air that the patent of the present invention uses, that is, oxygen is paramagnetic, has magnetotaxis in the magnetic field, and is attracted by magnetic force, and nitrogen is a diamagnetic substance, and nitrogen is repelled by magnetic lines of force in the magnetic field. More specific structure and magnetic line distribution are described as follows.

[0070] Figure 3 It is the basic structure of the arc-shaped warp magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14, that is, the schematic diagram of the structure of the basic magnetic circuit component 58 and the state and direction of the magnetic lines of force. The basic magnetic circuit component 58 is a primary processed component of the arc-shaped warp magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14. The structure of the basic magnetic circuit component 58 is composed of a pair of warp and latitude rare earth permanent magnet rings 78 with central holes and axial magnetization, with opposite magnetic poles facing each other, clamped on both sides of the flat narrow strip carrier 60, and the magnetic pole directions of each adjacent pair of warp and latitude rare earth permanent magnet rings 78 are consistent, and the center holes of the two opposite warp and latitude rare earth permanent magnet rings 78 are fixed in place with non-magnetic screws, such as Figure 3 As shown in (A); wherein the carrier 60 is a flat narrow strip carrier made of non-magnetic, corrosion-resistant, bendable and tangentially twistable material. Figure 3 (B) shows the magnetic field line distribution of the basic magnetic circuit component 58, and 59 is the magnetic circuit (magnetic field line N pole and S pole) formed by two longitude and latitude rare earth permanent magnet rings 78 with opposite magnetic poles facing each other on both sides of the flat narrow strip carrier 60.

[0071] The specific structure of the ball ring longitude and latitude magnetic circuit oxygen gathering device is shown in Figure 4 . Figure 4 The structure and deep processing status of the ball ring warp and weft magnetic circuit oxygen concentrator, the shape and structure of the twisted warp and weft magnetic circuit component 28, and the component structure and installation diagram of the arc warp magnetic circuit ring 13 and the circular weft magnetic circuit ring 14 are specifically given. The twisted warp and weft magnetic circuit component 28 starts from one end of the basic magnetic circuit component 58 and rotates in the same direction in sequence with the long center line of the carrier 60 as the axis until it rotates to the corresponding tail end of the basic magnetic circuit component 58, and the basic magnetic circuit component 58 is twisted into a twist shape, as shown in the figure. Figure 4 As shown in (A). Figure 4(B) is a schematic diagram of the spherical warp and weft magnetic circuit device for gathering oxygen and removing nitrogen and its installation. Among them, 26 is a plum blossom positioning plate at the extreme end after the upper hemispherical cover 1 and the lower hemispherical cover 2 are buckled. The arc warp magnetic circuit ring 13 is a magnetic circuit component that is installed in the warp direction by bending the twisted warp and weft magnetic circuit components 28 into an arc; the circular latitude magnetic circuit ring 14 is a magnetic circuit component that is installed in the latitude direction by bending the twisted warp and weft magnetic circuit components 28 into a circle. The arc warp magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14 are installed close to the inner wall of the large sphere buckled by the upper hemispherical cover 1 and the lower hemispherical cover 2. After the twisted warp and weft magnetic circuit components 28 are turned into arcs, the two ends are fixed in the plum blossom positioning plate 26 at the extreme end of the hemispherical cover, which is the arc warp magnetic circuit ring 13 in the warp direction of the warp and weft magnetic circuit of the ball ring, and there are several of them, which are evenly installed on the inner surface of the large sphere buckled by the upper hemispherical cover 1 and the lower hemispherical cover 2. The twisted warp and weft magnetic circuit components 28 are made into corresponding circles of different diameters, and are firmly installed at the equatorial position of the oxygen gathering space ball, as well as the positions of the latitude lines on the upper and lower sides of the equatorial circle, which constitute the circular latitude magnetic circuit ring 14 in the latitude direction of the warp and weft magnetic circuit of the ball ring, and there are several of them, which are symmetrically installed on the inner surface of the large sphere buckled by the upper hemispherical cover 1 and the lower hemispherical cover 2. Figure 4 (B) shows a magnetic oxygen gathering and nitrogen discharging space formed by interlacing a plurality of arc-shaped warp magnetic circuit rings 13 and a plurality of circular weft magnetic circuit rings 14. The above structure constitutes an oxygen gathering device of a spherical warp and weft magnetic circuit.

[0072] The directions of the magnetic force lines of the arc-shaped warp magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14 in the magnetic oxygen gathering and nitrogen expelling space are very special. The directions of these magnetic force lines are upward and downward, left and right, forward and backward, and in all directions. Because the upper hemispherical cover 1 and the lower hemispherical cover 2 are all made of carbon fiber, these magnetic force lines penetrate the sphere wall, so there is also a very strong magnetic field outside the sphere wall. Because the upper and lower hemispherical covers are made of non-magnetic stainless steel or carbon fiber, the magnetic force lines on the arc-shaped warp magnetic circuit and the circular latitude magnetic circuit in the sphere wall can penetrate the sphere wall, forming a strong magnetic field of multi-directional magnetic force lines inside and outside the sphere. Because oxygen is a paramagnetic substance, it has the property of tending to magnetize and approaching magnetism, and nitrogen is a diamagnetic material and is repelled by magnetism. The oxygen in the air will be sucked in when it encounters the magnetic lines of force here, and the nitrogen in the air will be repelled when it encounters the magnetic lines of force, or at least will not be sucked in. The nitrogen and other inert gases in the air do not like to stay in the magnetic space, so they float naturally and are naturally discharged from the exhaust port 70 into the big ball. A small amount is also sucked into the water by the high-end high-pressure fan 20.

[0073] In addition, when the high-end high-pressure fan 20 (see Figure 2) When the oxygen activating device is started, due to the strong suction of the fan, the gas in the ball is sucked down through the oxygen-enriched air inlet horn 27 at the top of the cylinder 5 of the oxygen activation device. At this time, the gas in the ball is sucked, the pressure in the ball is reduced, and the air outside the ball wall close to the outer surface with more oxygen flows in large quantities along the oxygen-enriched air flow direction 76 through the several air inlets 19 of the lower hemispherical cover 2 into the ball. According to the characteristics of aerodynamics, the friction (resistance) of air when flowing on the surface of a smooth streamlined object is very small, so the oxygen-enriched air on the outer surface of the ball is sucked into the ball unimpeded under the strong suction of the high-end high-pressure fan 20. The air that has undergone preliminary oxygen accumulation in the ball encounters a large number of multi-directional magnetic lines of force of the arc-shaped meridian magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14, which further enriches the air in the ball with oxygen. In particular, the dynamic magnetic lines of force sweeping outside the cylinder 5 of the oxygen activation device have a stronger magnetic effect on paramagnetic oxygen and antimagnetic nitrogen, which is more beneficial to oxygen concentration and nitrogen removal.

[0074] The distribution state and direction of all magnetic lines of force on the magnetic circuit of the oxygen gathering device of the spherical longitude and latitude magnetic circuit are very similar to the distribution state and direction of the bristles on the rod-shaped test tube brush. Therefore, the present invention uses the bristles on the test tube brush to simulate the distribution state of the magnetic lines of force and the direction of each magnetic line of force of the twisted longitude and latitude magnetic circuit component 28, the arc-shaped longitude magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14. Figure 4 All the magnetic lines of force of the braided warp and weft magnetic circuit component 28 are centered on the braided warp and weft magnetic circuit component 28, and all the directions they point to are in the radial direction, just like the bristles on a test tube brush (a rod-shaped brush specially used for cleaning test tubes and glass measuring cylinders) pointing to the surroundings and radiating outwards. The distribution state of the magnetic lines of force and the simulation diagram of the direction of each magnetic line of force can be seen in FIG. Fig.15 (A) and Fig.16 (A); Figure 4 The arc-shaped meridian magnetic circuit ring 13 in the meridian direction of the arc-shaped magnetic circuit has a magnetic field line distribution state and a simulation diagram of the magnetic field line direction, which can be found in Fig.15 (C); Figure 4 The simulation diagram of the magnetic field line distribution state and magnetic field line direction of the circular latitude magnetic circuit ring 14 in the latitude direction can be found in Fig.16 (O).

[0075] The present invention makes full use of the paramagnetic magnetotactic effect of oxygen and the diamagnetic magnetotactic effect of nitrogen according to Faraday's magnetic conductivity principle. This requires that the oxygen gathering space of the present invention be filled with a large number of magnetic lines of force oriented in different directions. This enables all oxygen and nitrogen in the oxygen gathering space of the present invention to be fully cut vertically by the magnetic lines of force and to be more processed by the magnetic effect, thereby obtaining a better oxygen gathering and nitrogen expelling effect.

[0076] Example 3 Structure of the dynamic oxygen activation device

[0077] Based on Example 1, Figure 2 , 5 , 6, 7, and 8 illustrate the structure of the dynamic oxygen activation device of the present invention.

[0078] The main structures of the dynamic oxygen activation device are as follows: 5 is the cylinder of the oxygen activation device (made of carbon fiber); 9 is the central axis, which is installed coaxially with the cylinder 5 of the oxygen activation device and can rotate at high speed; 6 is the central axis rare earth permanent magnet ring (with a hole in the center, axial magnetization, and when installed, the opposite magnetic poles of the two central axis rare earth permanent magnet rings 6 can be attracted and pressed against each other, so that the two permanent magnet rings form a group); 8 is the limiting sleeve; 10 is the central axis bearing, which is installed at both ends of the central axis 9; 11 is the positioning and fixing support rings fixed at both ends of the cylinder 5 of the oxygen activation device; 42 is the driving micromotor; 20 is the high-end high-pressure fan.

[0079] Figure 5 It is a schematic diagram of the oxygen activation device, the magnetic circuit structure, the distribution state of the magnetic lines of force, the direction of the magnetic lines of force, and the coupling state of the magnetic circuit and magnetic lines of force of the magnetic coupling. A plurality of groups of central axis rare earth permanent magnet rings 6 with holes in the middle are tightly sleeved on the central axis 9; a non-magnetic limiting sleeve 8 is sleeved on the central axis 9 and located between two adjacent groups of central axis rare earth permanent magnet rings 6, and the central axis rare earth permanent magnet rings 6 at both ends of each limiting sleeve 8 have the same magnetic polarity; because the central axis rare earth permanent magnet rings 6 at both ends of each limiting sleeve 8 have the same polarity, they repel each other, forming magnetic lines of force that are superimposed on each other due to the mutual repulsion of the same magnetic polarity, and the two adjacent N poles repel each other to form superimposed N pole superimposed magnetic lines of force 7, and the two adjacent S poles repel each other to form superimposed S pole superimposed magnetic lines of force 75; with the central axis 9 rotating at high speed in the cylinder 5 of the oxygen activation device as the axis, all the superimposed magnetic lines of force radiate radially to the outside of the circumference of the limiting sleeve 8 with this axis as the center, filling the space inside and outside the cylinder 5 of the oxygen activation device, and a considerable part of the magnetic lines of force penetrate the outer cylinder of the activation device, that is, the cylinder 5 of the oxygen activation device made of carbon fiber material. When the driving micro-motor 42 is started, the central shaft 9 is driven to rotate at high speed through magnetic coupling, driving a large number of superimposed magnetic lines to rotate at high speed around the central shaft 9 (see Example 4), so that a high-speed rotating dynamic magnetic field is generated inside and outside the cylinder 5 of the oxygen activation device, sweeping the space inside and outside the cylinder (see Figure 5 and Figure 7 ).

[0080] See also Figure 2 , Figure 2Among them, 76 is the flow direction of air entering the sphere; 17 is the flow direction of oxygen-enriched air; 12 is the guide cone; 18 is the flow direction of oxygen-enriched air with oxygen activated; 23 is an empty cylinder, which is the cylindrical space along the cylinder 5 of the oxygen activation device and the rare earth permanent magnet ring 6 on the central axis; 21 is the suction air inlet of the high-end high-pressure fan; 22 is the air outlet of the high-end high-pressure fan; 25 is a three-way or four-way; 24 is the pipeline leading to the gas storage bin. The oxygen in the air has a high specific gravity, while the specific gravity of nitrogen and other inert gases is small. They are also affected by the suction of the high-end high-pressure fan 20. Oxygen with a high specific gravity obtains more kinetic energy than nitrogen and other inert gases with a small specific gravity. Therefore, when the high-end high-pressure fan 20 sucks, more oxygen is sucked, while less nitrogen and other inert gases are sucked. These excess nitrogen and inert gases are naturally discharged from the several exhaust ports 70 at the top of the upper hemispherical cover 1. See Figure 2 A large amount of oxygen-rich air in the ball is strongly sucked by the high-end high-pressure blower 20, and the oxygen-rich air in the ball follows the flow direction 17 of the oxygen-rich air, enters the cylinder 5 of the oxygen activation device from the oxygen-rich air inlet bell mouth 27 at the top of the cylinder 5 of the oxygen activation device, and then continues to flow along the oxygen-activated oxygen-rich air flow direction 18 along the empty cylinder 23 to the bottom of the cylinder 5 of the oxygen activation device at a faster speed. In this process, the oxygen-rich air flows downward at a high speed. At the same time, when these activated oxygen-rich air passes through the empty cylinder 23 at a high speed, they must pass through a large number of strong magnetic lines of force that rotate at high speed and are perpendicular to their flow direction. N-pole superimposed magnetic lines of force 7 and S-pole superimposed magnetic lines of force 75, that is, each molecule of these oxygen-rich air flows through the magnetic lines of force of the rotating magnetic field that rotates at 2900 to 3000 revolutions per minute in the empty cylinder at a high speed (see Figure 5 ), all oxygen molecules must be cut by the massive high-speed rotating magnetic lines of force that are perpendicular to the direction of the oxygen molecules' advance, and the electron trajectory of the outermost layer of the oxygen nucleus is disturbed, so the physical and chemical properties of oxygen change, and oxygen becomes more active. The oxygen-enriched air activated by oxygen then flows through the outlet 22 of the high-end high-pressure blower, through the three-way or four-way 25, through the pipeline 24 leading to the air storage bin, and flows to the plug flow aeration device.

Figure 6In the figure, 10 is a high-quality and high-speed central shaft bearing at the upper and lower ends of the central shaft; 11 is a positioning and fixing support ring, which is installed at the upper and lower ends of the cylinder 5 of the oxygen activation device and fixed on the inner wall of the cylinder 5 of the oxygen activation device; 15 is a bearing seat of the central shaft bearing 10, and the bearing seat 15 is installed on the same plane as the positioning and fixing support ring 11; 16 is three bird-wing-shaped tie bars connecting the positioning and fixing support ring 11 to the bearing seat 15; 12 is a guide cone for inlet and outlet airflow; 23 is an empty cylinder, which is a cylindrical space along the cylinder 5 of the oxygen activation device and the central shaft rare earth permanent magnet ring 6. The positioning and fixing support ring 11 and the bearing seat 15 are connected by three bird-wing-shaped tie bars 16 evenly distributed at an angle of 120°, so as to position the central shaft 9.

[0082] Figure 8 yes Figure 5 BB cross-sectional view is a schematic cross-sectional view of the middle part of the cylinder 5 of the oxygen activation device. Figure 8 Among them, 5 is the cylinder (i.e., outer cylinder) of the oxygen activation device; 6 is the rare earth permanent magnet ring of the central axis; 9 is the central axis; 23 is the empty cylinder, which is the unobstructed air path for the flow of oxygen-enriched air and activated oxygen-enriched air.

[0083] In short, under the action of multiple dynamic and static magnetic fields inside and outside the large sphere formed by the upper hemispherical cover 1 and the lower hemispherical cover 2, plus the strong suction of the high-end high-pressure blower 20, the work of oxygen gathering, nitrogen removal and oxygen activation is completed at the same time. The whole process of completing the oxygen-enriched activation of the whole machine is: because there is a space with a fairly strong magnetic field inside and outside the sphere wall, the oxygen in the air in the magnetic space on the outer surface of the sphere is mostly close to the surface of the sphere due to the magnetotropy of oxygen, while the diamagnetic force of nitrogen is mostly repelled away from the outer surface of the sphere. When the high-end high-pressure blower 20 is turned on, due to the strong suction of the high-pressure blower, the oxygen-enriched air on the outer surface of the sphere is sucked into the sphere through the several air inlets 19 on the lower hemispherical cover 2 along the air flow direction 76. Because the outer surface of the sphere is a smooth sphere, which can be regarded as a streamlined shape, these oxygen-enriched air are sucked into the sphere unimpeded. After the magnetic field magnetic effect of more directional magnetic lines of force once again fully gathers oxygen and discharges nitrogen in the ball, the oxygen-enriched air is sucked by the high-pressure fan again along the flow direction 17 of the oxygen-enriched air through the bell mouth 27 of the oxygen-enriched air intake at the upper end of the oxygen activation device, and after being diverted by the guide cone 12, it enters the empty cylinder 23 between the cylinder 5 of the oxygen activation device and the outer diameter of the central axis rare earth permanent magnet ring 6 with a hole in the center, and enters the suction air inlet 21 of the high-end high-pressure fan along the flow direction 18 of the oxygen-activated oxygen-enriched air. The oxygen-enriched air is cut and activated by the high-speed rotating magnetic lines of force in the empty cylinder 23, and then enters the three-way or four-way of the oxygen-activated air pipeline from the outlet 22 of the high-end high-pressure fan, and then is sent to the air storage bin through the pipeline 24 leading to the air storage bin, thus completing the whole process of oxygen-enriched activation of the whole machine.

[0084] The functions of the oxygen gathering device and the oxygen activation device are interrelated and cannot be clearly separated, that is, the oxygen activation device also plays the role of gathering oxygen, and the oxygen gathering device also has the function of oxygen activation. In the spherical space of oxygen gathering and activation, the oxygen activation device has more magnetic lines of force in more directions to further gather oxygen, and the nitrogen here is once again magnetically repelled, and at the same time, it is also subjected to the strong suction effect of the high-end high-pressure fan 20. Because the specific gravity of oxygen in the air is large, under the same suction conditions, the dynamic energy obtained by oxygen being sucked is the largest, so most of the oxygen is sucked away and sent to the gas storage bin 41, so that some nitrogen and inert gas in the sphere of oxygen gathering and activation are naturally discharged from the exhaust port 70. The strong suction effect of the high-end high-pressure fan 20 also causes the air outside the ball to be quickly sucked into the ball, and further separates oxygen and nitrogen. The oxygen gathered by the oxygen gathering device flows in the ball and is affected by the magnetic lines of force of the arc-shaped meridian magnetic circuit ring 13 and the circular latitude magnetic circuit ring 14, and also has the effect of partially activating oxygen.

[0086] Based on Example 1, Figure 5 , 7 The structure and working principle of the driving micromotor 42 of the present invention are described.

[0087] Figure 7 It is a schematic diagram of the structural principle of magnetic coupling transmission of rotation. Figure 7 (B) is the natural state of the distribution and direction of the magnetic lines of force after the micro-motor rare earth permanent magnet disk 44 is axially magnetized; Figure 7 (A) is the state after coupling with the S-pole superimposed magnetic field lines 75 and the N-pole superimposed magnetic field lines 7, and is a schematic diagram of the distribution state and direction of the magnetic field lines after coupling with the micromotor rare earth permanent magnet disk 44. Figure 5 , 7 In the figure, 42 is the driving micromotor; 43 is the driving micromotor output shaft; 44 is the micromotor rare earth permanent magnetic disk (axial magnetization), which is coaxially installed at the top of the driving micromotor output shaft 43; 75 is the S-pole superimposed magnetic lines; 7 is the N-pole superimposed magnetic lines; 68 is the rotation direction of the driving micromotor output shaft 43 and the micromotor rare earth permanent magnetic disk 44; 69 is the rotation direction of the central axis 9 rotating at high speed in the cylinder of the oxygen activation device due to magnetic coupling; 45 is the dynamic magnetic field space, which is the coupling magnetic lines of the N-pole magnetic lines at the upper end of the micromotor rare earth permanent magnetic disk 44 with a hole in the center and the S-pole magnetic lines of the central axis rare earth permanent magnetic ring 6 in the oxygen activation device.

[0088] The high-speed rotating central axis 9 and the high-speed rotating magnetic lines in the cylinder 5 of the oxygen activation device are driven by magnetic coupling of the driving micro motor 42 outside the cylinder 5 of the oxygen activation device. The two adjacent groups of central axis rare earth permanent magnet rings 6 on the central axis 9 are opposite to each other with the same magnetic polarity, and the superimposed magnetic lines of force of the same magnetic polarity all radiate to the surroundings along the radial direction of the central axis rare earth permanent magnet ring 6 with the high-speed rotating central axis 9 of the oxygen activation device as the axis. Figure 5 , 7 7 is the N-pole superimposed magnetic force lines formed by the superposition of two groups of N magnetic poles, and 75 is the S-pole superimposed magnetic force lines formed by the superposition of two groups of S magnetic poles. The N-pole magnetic force lines of the axially magnetized micro-motor rare earth permanent magnetic disk 44 are aligned with the S-pole superimposed magnetic force lines 75 of the oxygen activation device, and the S-pole magnetic force lines of the micro-motor rare earth permanent magnetic disk 44 are aligned with the N-pole superimposed magnetic force lines 7 of the oxygen activation device, thus forming the attraction between opposite magnetic force lines to produce magnetic coupling.

[0089] Therefore, when the driving micromotor 42 is started, the superimposed magnetic field formed by the same magnetic polarity of each two groups of central axis rare earth permanent magnet rings 6 installed in series on the central axis 9 attracts and couples with the opposite magnetic force driven by the driving micromotor 42 outside the cylinder and rotating at high speed, thereby generating a dynamic magnetic field space 45 rotating at high speed inside and outside the cylinder, which is referred to as magnetic coupling drive.

[0090] During the magnetic coupling driving process, pay attention to the placement position and direction of the driving micromotor 42: when the output shaft end of the driving micromotor 42 is facing upward and close to the bottom end of the wall of the cylinder 5 of the oxygen activation device, the axis lines of the two are parallel; the N-pole magnetic lines of force of the axially magnetized rare earth permanent magnetic disk 44 of the micromotor correspond to a group of S-pole superimposed magnetic lines of force 75 at the bottom end of the magnetic circuit on the central axis of the cylinder of the oxygen activation device, and the S-pole magnetic lines of force of the axially magnetized rare earth permanent magnetic disk 44 of the micromotor correspond to the N-pole superimposed magnetic lines of force 7 on the central axis of the cylinder of the oxygen activation device. Their opposite magnetic poles will inevitably attract each other, producing a magnetic coupling effect.

[0091] After the driving micro motor 42 is started (see Figure 7 ), the micro-motor rare earth permanent magnet disk 44 rotates and couples along the direction shown in 68, and the N-pole superimposed magnetic force lines 7 in the oxygen activation device are coupled and synchronously rotate in the opposite direction along the direction shown in 69. As long as the micro-motor 42 is driven to start, the N-pole magnetic force lines of the micro-motor rare earth permanent magnet disk 44 rotate along the direction shown in 68, and due to the magnetic force coupling, the central axis 9 in the cylinder 5 of the oxygen activation device rotates synchronously. In addition, the superimposed magnetic force lines inside and outside the cylinder 5 of the oxygen activation device are all rotating at a high speed, so that the surrounding space inside and outside the cylinder of the oxygen activation device is full of high-speed rotating dynamic magnetic force lines. Such magnetic effect has a good effect on the activation of oxygen, and the magnetic force lines of the dynamic magnetic field that rotate at a high speed fully activate the oxygen.

[0092] Example 5: Structure and installation of buoy

[0093] The above embodiments 2 to 4 describe the partial equipment of the present invention that floats on water.

[0094] Based on Example 1, Fig.12 , Fig.12 The structure of a cylindrical flat-bottomed inclined-top buoy 55 is given.

[0095] Fig.12 In the figure, 55 is a cylindrical flat-bottomed slanted top buoy; 61 is a circular flat bottom surface of the cylindrical flat-bottomed slanted top buoy 55; 62 is a cylindrical side wall surface of the cylindrical flat-bottomed slanted top buoy 55; 64 is an elliptical slanted top surface at the top of the cylindrical flat-bottomed slanted top buoy 55; 56 is a buoy reinforcement device; 65 is an oblique cutting line cut at an appropriate angle in the middle of the cylinder when making the cylindrical flat-bottomed slanted top buoy 55; 62m is a longer screw rod welded at the center of the outer side of the buoy reinforcement device 56; 54 is a tubular nut with an inner thread matching the screw rod 62m; 62w is a locking positioning screw nut equipped with the screw rod 62m; 57 is the central axis of the cylindrical flat-bottomed slanted top buoy 55; 63 is the buoyancy direction of the circular flat bottom surface 61 of the buoy under water; 63k is a horizontal plane.

[0096] The specific structure of the cylindrical flat bottom inclined top buoy can be referred to Fig.12 This is a schematic diagram of the cylindrical flat-bottomed inclined-top buoy structure of the present invention. The circular flat bottom surface 61, the cylindrical side wall surface 62 and the elliptical inclined top surface 64 are welded to form a cylindrical flat-bottomed inclined-top buoy 55; a buoy reinforcement device 56 is installed on the cylindrical side wall surface 62; a longer screw rod 62m is welded at the center of the outer side of the buoy reinforcement device 56, and the tubular nut 54 on the edge of the load-bearing chassis 50 and the locking positioning screw nut 62w are used to connect and fix the cylindrical flat-bottomed inclined-top buoy 55 to the load-bearing chassis 50 (the structure of the cylindrical flat-bottomed inclined-top buoy 55 can be seen in Figure 1 ). According to the actual operation needs, the distance between the buoy center axis 57 of the cylindrical flat bottom inclined top buoy 55 and the overall center axis 73 of the device of the present invention can be controlled by adjusting the depth of the screw rod 62m screwed into the tubular nut 54. When the distance is adjusted to a suitable distance, it is fixed by locking the positioning screw nut 62w. There are three cylindrical flat bottom inclined top buoys 55 installed at evenly distributed positions on the edge of the equilateral triangle or circular load-bearing chassis 50 in the whole device.

[0097] According to the real weight of the present invention, the accurate buoyancy is calculated, the appropriate displacement is calculated, and then the diameter and height of the float are calculated. When making, first cut a rectangular stainless steel plate with appropriate length and width, roll the rectangular stainless steel plate into a standard cylinder, and then cut the upper and lower sections symmetrically at a 45° angle in the middle of the cylinder, which is the cylindrical side wall surface 62 of the float. Fig.12The 65 in (B) is the oblique elliptical cutting line in the middle of the cylinder. Welding an elliptical stainless steel plate to the oblique mouth of the ellipse will form the elliptical oblique top surface 64 of the float. Welding another circular stainless steel plate to the circular mouth of the circular cylinder will form the circular flat bottom surface 61 of the float. From the manufacturing process of the cylindrical flat bottom oblique top float 55, it can be seen that as long as two cuts are made on the raw material, a rectangular shape will be produced (see Fig.12 A), roll up a cylinder and weld a weld to make two cylindrical side walls 62, then weld the circular flat bottom 61 and the elliptical inclined top 64, and weld three seams (three welding lines) in total. It can be seen that the buoy is particularly labor-saving and labor-saving during blanking and manufacturing, with very little scrap and low cost.

[0098] The cylindrical flat-bottomed sloping-top buoy bears the buoyancy of the present invention floating on the water surface. When the equipment is impacted by wind and waves on the water surface or other external impact forces, because the buoy has a circular side wall, a flat bottom and a sloping top, the impact caused by the external force is minimal, ensuring that the equipment runs smoothly, has high working efficiency and extends its service life. Fig.12 The following diagram shows the decomposition of the impact forces of the cylindrical flat-bottomed buoy 55 when it encounters wind, waves and rainstorms from various directions, where 63a is the horizontal impact force; 63h is the direction of the force decomposed to both sides; 63b is the direction of the water surface impact force sliding upward along the slope; 63c is the downward impact force; and 63d is the direction of the component force of the downward impact force. The horizontal impact force 63a of the wind and waves on the cylindrical side wall 62 of the buoy is decomposed to both sides, and the impact force on the buoy can be reduced by about 50% (see Fig.12 E). After the wind and waves from the water surface hit the elliptical inclined top surface 64 of the buoy, the impact force climbs up along the 45° slope (direction 63b), and the impact force of the wind and waves can be reduced by at least 50% (see Fig.12 63c is the downward impact force of heavy rain and strong wind from above. When it encounters the elliptical inclined top surface 64 of the buoy, the downward impact force is decomposed (direction of component force 63d). At this time, the impact force on the buoy must be reduced by at least 60% (see Fig.12 D). Note that the bottom area of ​​the cylindrical flat bottom sloping top buoy 55 is relatively large compared to the side surface and the sloping top surface. Therefore, the damping effect when subjected to the buoyancy 63 is large. When the buoy is impacted by an external force, the greater the impact force, the stronger the damping effect. Stronger damping effect will make the whole machine run more stably, more efficient and have a longer service life.

[0099] Example 6 Plug flow aeration device

[0100] The plug flow aeration device is the underwater part of the device of the present invention, and the device mainly includes a submersible motor 31, a bird-wing-shaped magnetic guide plate 34, and a small submersible motor 49.

[0101] Based on Example 1, Fig. 9 and Fig.11 , explain the structure and function of the plug flow aeration device.

[0102] Reference Fig.11 , Fig.11 Among them, 31 is a submersible motor; 33 is a propeller blade; 34 is a bird-wing-shaped magnetic guide plate; 35 is a rare earth permanent magnet ring of the guide plate installed in the bird-wing-shaped magnetic guide plate 34; 38 is the trajectory of small bubbles of water-gas mixture, that is, the direction of the water-gas mixture running far away along the parabolic trajectory and the spiral trajectory; 49 is a small submersible motor that pushes sewage and sludge vertically to the bottom of the pool; 50 is an equilateral triangle or circular load-bearing chassis; 48 is a downward push-flow blade on the output shaft of the small submersible motor vertically downward; 55 is a cylindrical flat-bottomed sloping-top buoy; 66 is a swirling state of the water-gas mixture in the push-flow service area close to the propeller blades; 67 is a swirling state of the water-gas mixture in the push-flow service area far away from the propeller blades.

[0103] The submersible motor 31 can be Fig.11 Install 3 units evenly, or Fig.14 The submersible motor 31, the propeller blades 33 and the Figure 1 The submersible motor output shaft 32, hollow main shaft 29, stirring and crushing blades 37, air storage bin 41, submersible motor bearing 40, coupling 39 related to the submersible motor 31, as well as the positions and connection relationships therebetween can be found in the plug flow aeration device disclosed in Patent No. 201510697753.7.

[0104] Fig. 9 Is installed in Figure 1 A schematic structural diagram of the hollow main shaft 29 on the axis line of the air storage bin 41 and the oblique centripetal pressurized air inlet 30 on its side wall. Fig. 9In the figure, 29 is a hollow main shaft, which is coaxially connected to the output shaft 32 of the submersible motor through a coupling 39, and the outer end is equipped with a propeller blade 33, and the inner hole of the outer end is equipped with a mixing and crushing blade 37. The outer side of the hollow main shaft 29 is coaxially surrounded by an air storage bin 41; 30 is an oblique centripetal boost air inlet, and several of them are opened on the side wall of the hollow main shaft 29; 85 is the rotation direction of the hollow main shaft 29; 86 is the airflow direction of the high-pressure oxygen-rich (activated oxygen) air in the air storage bin being sucked into the hollow main shaft 29 by the oblique centripetal boost air inlet 30 on the side wall of the hollow main shaft 29. The oxygen-rich air activated by the dynamic oxygen activation device is forcefully blown into the air storage bin 41 by the high-end high-pressure blower 20. When the hollow main shaft 29 rotates at high speed along the direction of 85, the activated oxygen-enriched air in the air storage bin 41 is centripetally pressurized by the oblique centripetal supercharged air inlet 30, and the oxygen-enriched air activated by the oxygen is ejected into the water at the tail end of the hollow main shaft 29 under the effect of the vacuum negative pressure generated by the strong push flow of the propeller blade 33. At the same time, the vacuum negative pressure generated by the strong push flow of the propeller blade 33 increases the suction effect on the oxygen-enriched air activated by the oxygen sent into the air storage bin 41, and pushes a large amount of the activated oxygen-enriched air into the water under increased pressure. The activated oxygen-enriched air that is strongly sucked into the water reaches the very tail end of the hollow main shaft 29, and is mixed with water and gas at the water and gas contact surface. Three or four oxygen-enriched air stirring and crushing blades 37 are evenly welded on the end surface of the rear end of the hollow main shaft 29, and the oxygen-enriched air activated by oxygen and the water are fully mixed at the water-gas interface, and the bubbles of oxygen-enriched air crushed in the water are particularly small (the diameter of these small bubbles is more than 5 times smaller than the bubbles produced by the existing microporous aeration equipment, which are 1mm±0.3mm). These tiny bubbles form a water-gas mixture here. Of course, these water-gas mixtures also contain impurities such as sludge and sand.

[0105] The state of the "ball ring longitude and latitude magnetic circuit oxygen gathering dynamic activation oxygen aeration aerator" of the present invention during actual field application is shown in FIG. Fig.11 When the machine is just started, the blades of the propeller forcefully push a large amount of water and sludge and dynamically activated oxygen-enriched air bubbles, and under the guidance of the bird-wing-shaped magnetic guide plate 34, they are pushed forward in a swirling manner along a parabolic route. At this time, the overall outward diffusion swirling state is shown in FIG. Fig.1166. Because the oxygen-rich bubbles are very small and light, they move along the spiral trajectory to the inflection point of the parabola and float to the water surface due to the buoyancy of the water. When these bubbles reach the inflection point, the oxygen inside is basically dissolved in the water. When these small air bubbles begin to float to the water surface, they absorb various types of grease, viscous substances and various floccules in the sewage until they float to the surface. This is the good flotation effect of this machine. At this time, a large amount of water and sludge continue to swirl forward along the parabola and begin to diffuse until all the swirls of the present invention are connected into pieces and radiate and diffuse to the surroundings, achieving the purpose of expanding the service water body. Fig.11 of 67.

[0106] Example 7: Bird-wing shaped magnetic deflector

[0107] Based on Example 1 and Example 6, Fig.10 The structure and function of the bird-wing shaped magnetic deflector 34 are described.

[0108] In order to improve the efficiency of sewage aeration and oxygenation of the present invention, expand the service area of ​​sewage water body, and most reasonably control the flow direction of the pushed water-gas mixture, the greatest efforts are made to realize that the actual trajectory and distance of the tiny bubbles of oxygen-rich air in the sewage are longer and farther, and the small bubbles stay in the sewage for a longer time, so that the activated oxygen in these small bubbles can be completely dissolved in the sewage, achieving a very high oxygen transfer rate. The present invention creates a diversion device that can be adjusted in three dimensions (angle, direction, position) at will, that is, a bird-wing-shaped strong magnetic effect diversion plate, see Figure 1 .

[0109] In order to control the direction of the jet of the water vapor mixture, three bird-wing-shaped magnetic deflectors 34 are installed just in front of the propeller blades 33. Fig.10 (A), 36 is an equilateral triangle axis frame, a device for adjusting the three-dimensional angle, direction and position of the bird-wing shaped magnetic deflector 34; 36a is a sleeve that can rotate freely on the center position of each side of the equilateral triangle axis frame 36; 36b is a tubular long screw nut welded to the middle position of the sleeve 36a and perpendicular to it; 36c is a long screw for adjusting the front and rear distance of the bird-wing shaped magnetic deflector 34, fixed at the wing root of the bird-wing shaped magnetic deflector 34; 36d is a locking nut for adjusting the front and rear distance of the bird-wing shaped magnetic deflector 34; 35 is a guide plate rare earth permanent magnet ring, the center of which has a hole for axial magnetization and is installed on the center line of the bird-wing shaped magnetic deflector 34. Fig.10(C) is the magnetic force line distribution state of the guide plate rare earth permanent magnet ring 35 and the direction of the N and S poles, wherein 36f is the magnetic force line of the N pole of the guide plate rare earth permanent magnet ring 35, and 36g is the magnetic force line of the S pole of the guide plate rare earth permanent magnet ring 35. 36h is the central sandwich plate of the bird-wing-shaped magnetic guide plate 34 made of Q235A iron plate (magnetic conductivity), and a guide plate rare earth permanent magnet ring 35 with a hole in the center is installed on each of the two opposite magnetic poles on the two faces of the central sandwich plate 36h, and the central holes of the two guide plate rare earth permanent magnet rings 35 on the two opposite faces of the central sandwich plate 36h are penetrated and fixed by iron screws. There are several pairs of guide plate rare earth permanent magnet rings 35 with holes in the center evenly distributed on each bird-wing-shaped magnetic guide plate 34. 36K is a guard plate clamped on and below the bird-wing-shaped magnetic deflector 34. The guard plate 36K is made of a carbon fiber plate. The two guard plates 36K keep the central sandwich plate 36h and the deflector rare earth permanent magnet ring 35 in a sealed and protected state.

[0110] When the bird-wing-shaped magnetic deflector 34 is initially installed, its longitudinal center line should be parallel to the central axis of the hollow main shaft 29, and the longitudinal center line of the bird-wing-shaped magnetic deflector 34 should be evenly distributed on the periphery of the hollow main shaft 29, and three-dimensional adjustment should be performed according to the standard, and it should be locked and fixed after adjustment. In actual application, three-dimensional (angle, direction and position) adjustment can be performed according to the actual situation on site, usually adjusted to an angle of about 30° with the water surface.

[0111] Three evenly distributed bird-wing-shaped magnetic guide plates 34 are installed in front of each propeller blade 33. When the device for adjusting the three-dimensional angle, direction and position of the bird-wing-shaped magnetic guide plate 34 is adjusted to the optimal state, the water vapor and sludge jet stroke ejected by the push flow can reach a farther distance. The flow direction of the water vapor and sludge pushed by the push flow can be horizontal, and can also be tilted at an appropriate angle to be ejected underwater according to the depth of the water. The water pushed by the strong push flow and the oxygen-enriched air and sludge activated by oxygen pass through the guide of the bird-wing-shaped magnetic guide plate 34, and the route of forward flow is a parabola; the running trajectory of the oxygen-enriched air activated by oxygen, the sludge particles and the water is a swirl shape, and the direction of the swirl is consistent with the push flow slope of the propeller blade 33. When the water and sludge pushed by the push flow are fully cut vertically by the magnetic lines of force of the N pole and the S pole on both sides of the guide plate rare earth permanent magnet ring 35, the hydrogen bond of the water is affected by the magnetic effect, and the polarity of the water is enhanced. By increasing the surface tension and oxygen dissolving capacity of water, the affinity between oxygen and water will naturally be strengthened. Under the influence of the magnetic effect, small particles of sludge and some impurities and harmful substances are more likely to gather, which can greatly increase the sedimentation speed of sludge.

[0112] After the oxygen-enriched small bubbles activated by oxygen are sprayed into the water, their trajectory moves forward along the spiral line. When they encounter water with enhanced polarity and increased surface tension due to the magnetic effect, the activated oxygen has a strong affinity with water, and the oxygen in the small bubbles is very easy to dissolve in the water. When the small bubbles run at the inflection point of the parabola, the activated oxygen in the small bubbles has been completely dissolved in the water. When the small bubbles stop running forward and float to the water surface due to the buoyancy of the water, during this process, because the surface tension of the interface between the air and water of the small bubbles is very large, the grease and suspended matter in the water are easily adsorbed by the small bubbles on the surface of the bubbles to form hollow balls, which is a good flotation effect. Moreover, the trajectory of the small bubbles in these water-gas mixtures is a spiral line, so the actual distance traveled by the small bubbles and the time they stay in the water are far longer than the time and the travel and distance of the bubbles in the microporous aeration equipment, and are extended to more than fifteen times.

[0113] In the prior art, a flow guide device, such as a Laval cylindrical flow guide cover, is also installed in front of the propeller blades. However, the three evenly distributed bird-wing-shaped magnetic flow guide plates 34 of the present invention can more reasonably control the flow direction of the water-gas mixture being pushed, and the actual trajectory and distance of the tiny bubbles of oxygen-enriched air in the sewage are longer and farther, and the stay time is longer, thereby improving the oxygen transfer rate.

[0114] Embodiment 8 Small submersible motor

[0115] Based on Example 1 and Example 6, see Figure 1 and Fig.11 The installation position and function of the small submersible motor 49 are further explained.

[0116] Figure 1 and Fig.11 In the figure, 49 is a small submersible motor for vertically pushing flow downward; 47 is an output shaft of the small submersible motor; 48 is a downward propeller blade of the small submersible motor, which is installed at the lower end of the output shaft 47 of the small submersible motor. The small submersible motor 49 is installed at the position of the lower end center axis 73 of the device of the present invention.

[0117] The equipment of the present invention pushes all sewage and sludge around the central axis 73 of the machine and diffuses them outward in a swirling manner. In this case, a large amount of sludge is piled up into a "mountain" at the position of the equipment vertically underwater, which will affect the effect and efficiency of sewage treatment. For this reason, a small submersible motor 49 is installed at the underwater position of the central axis 73 of the equipment, and the downward push paddle blades 48 push the flow vertically downward to blow up the sludge accumulated under the machine, which is then pushed away by the swirling flow behind other push flows to diffuse to the surrounding swirling flow.

[0118] Example 9 Reference Fig.14 Explain the overall working process of the present invention

[0119] Based on Example 1, Figure 1 and Fig.14 The overall working process of the present invention is described.

[0120] See Fig.14 , the upper hemispherical cover 1 and the lower hemispherical cover 2 are buckled together to form a spherical body. Because the two hemispherical covers are made of carbon fiber or non-magnetic stainless steel, arc-shaped meridian magnetic circuit rings 13 and circular latitude magnetic circuit rings 14 are installed near the inner wall of the ball. These magnetic circuits are all close to the inner surface of the sphere. Most of the magnetic lines of force of these magnetic circuits are inside the ball, and another part is transmitted to the outer surface layer of the ball. That is to say, there are densely distributed magnetic lines of force in the space inside the ball and the outer surface layer. Because the oxygen in the air is a paramagnetic substance with magnetotaxis, there is more oxygen in this layer of air. Nitrogen in the air is a diamagnetic substance, which is repelled by magnetism, or at least nitrogen is not attracted by magnetism, so there is more oxygen and less nitrogen in the magnetic space on the outer surface of the ball. When the high-end high-pressure fan 20 is started, the oxygen-rich air on the outer surface of the ball is sucked in unimpeded due to the strong suction effect of the high-pressure fan, and enters the ball along the air flow direction 76 entering the ball through the plurality of air inlets 19 on the lower hemispherical cover 2. Because the outer surface of the ball is a smooth sphere, which is also a streamlined body in the air, the oxygen-rich air on the outer surface of the ball is easily sucked into the ball.

[0121] Fig.14 In the figure, 17 is the flow direction of oxygen-enriched air; 18 is the flow direction of oxygen-enriched air with activated oxygen; 23 is an empty cylinder, that is, the cylindrical space between the cylinder 5 of the oxygen activation device and the rare earth permanent magnet ring 6 of the central axis, that is, the smooth air path of the oxygen-enriched air with activated oxygen; 21 is the suction air inlet of the high-end high-pressure blower connected to the lower end of the oxygen activation device; 45 is the dynamic magnetic field space, which is the superimposed magnetic field formed by the same magnetic polarity of each two groups of central axis rare earth permanent magnet rings 6 installed in series on the central axis 9 in the activation barrel, and the high-speed rotating magnetic field of the micromotor rare earth permanent magnet disk 44 on the micromotor 42 outside the cylinder, and the high-speed rotating dynamic magnetic field space inside and outside the cylinder generated by the mutual attraction and coupling of opposite magnetic forces; 70 is the exhaust port of excess air such as nitrogen, hydrogen, and inert gas with lighter specific gravity; 76 is the flow direction of air entering the ball from the air inlet 19.

[0122] When the high-end high-pressure fan 20, the driving micro-motor 42 and the underwater submersible motor 31 are started synchronously, the high-end high-pressure fan 20 has a strong suction effect, the oblique centripetal supercharging air inlet 30 on the side wall of the hollow main shaft 29 in the air storage tank 41 has a centripetal supercharging effect, and the propeller blades 33 on the submersible motor 31 have a strong push flow, and the negative pressure suction effect generated at the axial line position near the propeller and the blades makes the oxygen-enriched air inside and outside the ball formed by the upper and lower hemispherical covers pass through the oxygen-enriched air inlet bell mouth 27 along the oxygen-enriched air flow direction 17 and enter the cylinder 5 of the oxygen activation device. The oxygen-enriched air flows in the empty cylinder 23 along the flow direction 18 of the oxygen-enriched air where oxygen is activated, flows to the suction inlet 21 of the high-end high-pressure fan at a high speed, and enters the high-end high-pressure fan 20. In this process, the oxygen in the oxygen-enriched air must pass through a magnetic field perpendicular to the oxygen's forward direction when flowing forward at high speed in the air passage of the empty cylinder 23, that is, the same magnetic polarity such as the N pole passing through the central axis 9 corresponds to form a superimposed strong magnetic N pole, and the central axis rare earth permanent magnet ring 6 radiates in its radial direction to the N pole superimposed magnetic lines 7 of the space inside and outside the oxygen activation cylinder wall, and its direction is centered on the central axis of the central axis and radiates to the surrounding along the radial direction of the central axis rare earth permanent magnet ring 6; similarly, the superimposed S pole superimposed magnetic lines 75 are also centered on the axis of the central axis and radiate to the surrounding along the radial direction of the rare earth permanent magnet ring. In particular, after the driving micro-motor 42 of the coupled magnetic circuit is started, the energy transmitted by the magnetic coupling drives all the magnetic lines in the cylinder of the oxygen activation device, including the magnetic lines of force penetrating the outside of the cylinder 5 of the oxygen activation device, to rotate at a high speed of about 3,000 revolutions per minute; when the oxygen-enriched air enters the empty cylinder 23 from the bell mouth 27 of the oxygen-enriched air at the upper end of the oxygen activation device, it flows along the oxygen-activated oxygen-enriched air flow direction 18 and enters the high-end high-pressure blower 20. In this process, the oxygen-enriched air must pass through many high-speed rotating N-pole superimposed magnetic lines of force 7 and S-pole superimposed magnetic lines of force 75 of the same polarity. The directions of all the high-speed rotating superimposed magnetic lines of force in the cylinder are perpendicular to the direction of the high-speed flow of oxygen. After the oxygen is cut by these many vertical magnetic lines of force, the two electrons in the outer layer of the oxygen are disturbed, so the physical and chemical properties of the oxygen are changed, and the oxygen becomes more active.

[0123] The oxygen-enriched air fully activated by the oxygen activation device passes through the high-end high-pressure fan 20 through the suction inlet 21, the outlet 22, and the three-way or four-way 25 on the pipeline. After being diverted, it enters the pipeline 24 leading to the air storage bin, and then is sent to the air storage bin 41. A hollow main shaft 29 is installed in the air storage bin 41. An oblique centripetal booster air inlet 30 is arranged on the side wall of the hollow main shaft 29. One end of the hollow main shaft 29 is connected to the output shaft 32 of the submersible motor through a coupling 39. A propeller blade 33 is installed at the tail end of the hollow main shaft 29. The front of the blade is straight, and the blade is an oblique curved surface. A number of stirring and crushing blades 37 for oxygen-enriched air are welded on the edge of the tail end of the hollow main shaft. When the submersible motor 31, the high-end high-pressure blower 20, and the driving micro-motor 42 coupled with the magnetic circuit rotation are all started synchronously, the activated oxygen-rich air is sucked and pushed by the high-end high-pressure blower 20 and the oblique centripetal supercharged air inlet 30 on the side wall of the hollow shaft and the high-speed rotating propeller blades 33 to generate sufficient vacuum negative pressure suction, and a large amount of activated oxygen-rich air is mixed with water in the negative pressure area in front of the plug-flow propeller blades. The activated oxygen-rich air here is fully stirred in the interface area where the oxygen activated oxygen-rich air stirring and crushing blades 37 on the rear edge port of the hollow main shaft 29 and the water contact, and the diameter of the activated oxygen-rich air bubbles after crushing and stirring is 1mm±0.3mm. The activated oxygen-rich air originally ejected from the rear port of the hollow main shaft 29 has a sufficiently large kinetic energy, and the plug-flow propeller has a strong thrust force in this water-gas mixing area, so that the water-gas mixed liquid obtains greater kinetic energy and is ejected in a spiral shape to a farther front.

[0124] When the activated oxygen-rich air is ejected from the tail end of the hollow shaft 29 and meets water, at the interface where water and gas contact, on the port at the tail end of the hollow shaft 29, there are a number of oxygen-rich air stirring and crushing blades 37. There are high-speed rotating stirring blades on this water and gas contact interface. The activated oxygen-rich air is stirred into very small bubbles in the water. After these small bubbles are fully mixed with the water, they are strongly pushed by the propeller blades and flow along the parabolic path and spiral trajectory to a farther water area. The oxygen in the activated oxygen-enriched air in the small bubbles encounters the water treated by the magnetic effect at the bubble and water interface, because they have strong affinity, and because the actual walking track of these small bubbles in the water is a spiral line, and the running direction of the water-gas mixture is a parabola, that is, the water-gas synthesis body of the push flow is guided by the bird-wing-shaped magnetic guide plate 34, so that the direction of the push flow is an appropriate angle obliquely below the water. When the water-gas synthesis body of the push flow is shot to the appropriate position, the power energy consumption of the push flow is gone, and the small bubbles in the water no longer continue to move forward, but begin to float vertically to the water surface under the buoyancy of the water. Therefore, the actual walking distance of these oxygen-activated oxygen-enriched air bubbles in the water and the time they stay in the water far exceed the microporous aeration equipment of the blast pipeline type commonly used at home and abroad. The oxygen in the very small bubbles of the present invention can be more fully dissolved in the water. Therefore, the utilization rate and transfer rate of oxygen of the present invention far exceed all existing aeration and aerators.

[0125] The oxygen-enriched air bubbles generated by the device of the present invention are all dissolved in the water when they move along the spiral trajectory to the parabola inflection point. Because the surface tension of the spherical water surface of the small bubbles at the water-air interface is relatively large, the oil and grease in the water, the slightly viscous small particles in the sludge, the suspended matter in the water, and the flocculent matter are adsorbed on the surface of the small bubbles to form hollow balls that float on the water surface after moving to the parabola inflection point. This is the satisfactory effect of the good air flotation of the present invention.

[0126] Practice has proved that the oxygen transfer (utilization) rate of the "ball ring longitude and latitude magnetic circuit oxygen-gathering dynamic activated oxygen aeration and oxygen-increasing machine" of the present invention is about twice as high as that of the traditional microporous aerator, and the power efficiency of this machine is about twice as high as that of similar equipment of the American Eloxy Company and the American Aleutian Company. The sludge discharge is reduced by one third compared with the traditional equipment, and the power consumption of this machine is about one quarter to one third less than that of the traditional equipment. The noise of this machine is 20% less than that of the equipment of the American Aleutian Company and the Eloxy Company.
