Description

Technical Field

[0001] The utility model relates to the technical field of sterilization devices, in particular to an interventional high-gradient magnetic field and high-frequency electric field liquid flow sterilization treatment device. Background Art

[0002] In water bodies, algae are one of the common microbial organisms. Excessive algae reproduction may lead to water quality deterioration, ecological damage and other environmental problems. The latest version of the National Sanitary Drinking Water Standard uses three indicators such as algae toxins, geosmin, and 3.2-methylisoborneol to control the content of algae. Therefore, controlling and killing algae is crucial to maintaining the ecological balance of water bodies. The principle of high-gradient magnetic field algae killing is to use high-gradient magnetic fields to act on algae cells, interfering with their normal physiological and metabolic processes, thereby achieving the purpose of killing and inactivation. High-gradient magnetic fields can change the ion concentration inside and outside the cells, destroy the integrity of the cell membrane, damage organelles and DNA or RNA, and then cause cell death.

[0003] However, the traditional method of applying medicine to kill algae will produce the drawbacks of drug resistance and incomplete killing, and will also cause harm to human tissues. Utility Model Content

Due to the change in the osmotic pressure difference between the tissue fluid inside and outside the bacterial wall and the impact of the electron flow vortex and the magnetic seed deflection jet, the bacterial wall is destroyed, and the intracellular plasma flows out, thereby achieving the effect of killing bacteria in the solution. In addition, no thermal effect will be generated during the sterilization process, the physical and chemical properties of the solution will not be changed, and there is no radioactivity. Since the electromagnetic field has strong penetration and no dead corners are generated, the sterilization effect is better than traditional sterilization technology.

[0043] In order to solve the problems pointed out in the background technology, combined with reference Figure 1 and Figure 2As shown, the utility model proposes an interventional high-gradient magnetic field and high-frequency electric field liquid flow sterilization treatment device, including an ultrasonic intervention magnetic seed homogenizer (not shown), a sterilization unit 10, a backwashing structure (not shown) and a sludge concentration anaerobic reactor 20, which is used to homogenize the powdered nano-scale magnetic iron powder in the solution to be treated; the sterilization unit 10 includes a high-gradient magnetic field structure 11 and a high-frequency electric field structure (not shown), the high-gradient magnetic field is provided with a water inlet (not shown) and an electromagnetic flowmeter (not shown), which are used to pass the solution to be treated, and the high-frequency electric field structure includes a cathode 23 and an anode 22, the cathode 23 is vertically arranged in the center of the high-gradient magnetic field structure 11, and the anode 2 2 is connected to a high-voltage shielded wire and electrically connected to a high-power high-frequency generator, the anode 22 of the high-power high-frequency generator is electrically connected to the outer shell of the high-gradient magnetic field structure 11; a water outlet (not shown) is provided at the bottom of the high-gradient magnetic field structure 11, the water outlet (not shown) is simultaneously connected to a backwashing water inlet (not shown), a purified water outlet (not shown) and a floc outlet (not shown), the backwashing structure is connected to the backwashing water inlet at the bottom of the high-gradient magnetic field, and is used to backwash the interior of the high-gradient magnetic field, and the sewage after flushing is discharged from the floc outlet; the sludge concentration anaerobic reactor 20 is connected to the floc outlet, and is used to purify the sewage after flushing.

[0044] Ultrasonic intervention magnetic seed homogenizer uses the cavitation effect and other physical effects of ultrasound in liquid to achieve the homogenization effect. Ultrasound can make the magnetic seeds evenly distributed in the solution to be treated. Physical effect refers to the fact that ultrasound can form effective stirring and flow in the liquid to destroy the structure of the medium and crush the particles in the liquid. It is mainly the collision between liquids, microphase flow and shock waves that cause changes in the surface morphology of particles. Cavitation refers to the fact that under the action of ultrasound, the liquid produces cavities, i.e. small bubbles, in places with weaker intensity. The small bubbles pulsate with ultrasound, and the cavities collapse within a sound wave cycle. Ultrasonic cavitation also produces strong mechanical effects, generating fast jets or sonic streams near the solid interface and strong shock waves in the liquid. Thus, the magnetic seeds can be evenly distributed in the treated solution. The magnetic seeds can be a nano-scale ultrafine particle ferroferric oxide powder. The decontamination mechanism of iron ions is: first, the replacement and oxidation of iron ions, which can replace almost all heavy metals in sewage. Other ions or compounds with strong oxidizing properties can be reduced by iron to a reduced state with less toxicity. For example, dyes can be directly reduced to amino organic matter in a slightly acidic aqueous solution. Some heavy metal ions in wastewater can also be reduced by iron, for example, amino organic matter is light in color and easily oxidized and decomposed, so the color of wastewater can be reduced; second, micro-electrolysis, iron has electrochemical properties. The new ecological [H] and Fe2+ in the products of its electrode reaction can undergo redox reactions with many components in wastewater, which can destroy the color or color-aiding base of the dye, causing it to break the chain and lose its color-forming ability; it can decompose macromolecules into small molecular intermediates; it can make some chemical substances that are difficult to biodegrade become substances that are easy to biodegrade, thereby improving the biodegradability of water; third, coagulation and adsorption, when treating wastewater under acidic conditions, a large amount of Fe2+ and Fe3+ are produced. When the pH is adjusted to alkaline and oxygen is present, Fe(OH)2 and Fe(OH)3 flocculent precipitation will be formed. Fe(OH)3 may also be hydrolyzed to form complex ions such as Fe(OH)2+ and Fe(OH)+2, which all have strong complex flocculation properties. In this way, the original suspended matter in the wastewater, as well as the insoluble substances produced by micro-electrolysis and the insoluble substances that constitute the color can all be adsorbed and condensed, thereby purifying the wastewater.

[0045] After the magnetic species are homogeneously distributed in the treated solution, they are introduced into the sterilization unit 10. The sterilization unit 10 can generate Lorentz force and electron vortex, as well as instantaneous high-speed movement of the magnetic species, by the synergistic effect of high-gradient magnetic field and high-frequency electric field. The negatively charged ions in the solution are deflected under the action of the high-gradient magnetic field Lorentz force. At the same time, under the dual action of the electron vortex, the bacterial cell wall is instantly broken down, causing the bacterial plasmolysis to flow out and causing cell death; furthermore, after the osmotic pressure of the solution changes instantly, the solution "moves" into the cell wall through the ion permeation effect of the cell wall, thereby causing the cell wall to be broken, which is also the cause of bacterial death. In theory, the magnetic force (F m) exerted on the particles in the solution is positively correlated with the magnetic field intensity (H), magnetic field gradient (dH / dx) and magnetic susceptibility (x), volume (V) of the particles. Therefore, under the same magnetic field intensity, the higher the gradient of the magnetic field, the stronger its action ability. Compared with the conventional magnetic field, it has the rule that the higher the gradient difference, the stronger the action ability and the better the action effect. The interventional high-gradient magnetic field and high-frequency electric field solution sterilization treatment device has the characteristics of high treatment efficiency, easy to realize automatic control, long equipment life, no need to replace filter materials, and small footprint. Most importantly, the interventional high-gradient magnetic field and high-frequency electric field solution sterilization treatment device does not change any physical and chemical properties of the treated solution during the sterilization process, and completely retains the flavor, taste and all chemical structure components of the treated solution. Compared with traditional equipment with the same processing capacity, the high-gradient magnetic field and high-frequency electric field solution sterilization treatment device occupies only 25% of the traditional equipment, which can save a lot of infrastructure investment and room heating management costs.

[0046] Specifically, with reference to Figure 1 As shown, the high gradient magnetic field structure 11 includes a yoke shell 111, a separation cavity 112 and an electromagnetic coil 113; the separation cavity 112 is arranged in the yoke shell 111, and the separation cavity 112 is filled with fibrous steel wool 1121; the electromagnetic coil 113 is wound around the outer wall of the separation cavity 112.

[0047] When powered on, the electromagnetic coil 113 generates a magnetic field, and the magnetic particles in the solution flowing through the steel wool 1121 are acted upon by the magnetic force in the magnetic field and captured by the steel wool 1121. In theory, the magnetic force (Fm) exerted on the particles is positively correlated with the magnetic field strength (H), magnetic field gradient (dH / dx), magnetic susceptibility (x) and volume (V) of the particles. Therefore, under the same magnetic field strength, the separation ability of the high gradient magnetic separator is higher than that of the conventional magnetic separation technology. The higher the gradient, the stronger the separation ability and the stronger the effect.

[0048] Magnetic field gradient refers to the change in magnetic field intensity per unit distance. Under a certain magnetic field intensity, the height of the gradient is related to the magnetization intensity, shape, diameter, filling rate, etc. of the matrix. The fibrous steel wool 1121 matrix has high magnetization intensity, many sharp edges, small diameter, low filling rate (4-6%), and a gradient of up to 1000 gauss / micron, which is unmatched by any other magnetic filter material. Therefore, the high-gradient magnetic separator using the steel wool 1121 matrix can separate weakly magnetic nanoparticles with low magnetic susceptibility and small volume that cannot be separated by general magnetic separators. In addition, the steel wool 1121 matrix also has certain physical and chemical stability, small coercive force, many capture points, and good passing performance. It is currently recognized as the best high-gradient magnetic field matrix material.

[0049] Furthermore, grate plates 1122 are provided at the top and the bottom of the separation channel 112 .

[0050] The grate plate 1122 is provided at the top of the separation channel 112 to filter the solution to be treated and remove the impurities with relatively large particles in the solution. The grate plate 1122 is provided at the bottom of the separation channel 112 to filter the treated purified water and prevent the impurities such as flocs attached to the steel wool 1121 from falling into the purified water.

[0051] It should be noted that after a period of treatment, the surface of the steel wool 1121 reaches saturation, and the disinfection ability decreases, and it is necessary to turn off the power to demagnetize and use water to backwash the steel wool 1121. Therefore, a backwashing structure can also be set to flush the magnetic seeds into the flushing water anaerobic concentration tank. Due to the high density of the magnetic seeds, they gradually settle to the bottom and can be reused after recycling.

[0052] Specifically, in one embodiment of the present application, the backwash structure includes an anaerobic flushing water concentration tank (not shown), a backwash pump (not shown) and a backwash element (not shown), and the backwash pump is respectively connected to the anaerobic flushing water concentration tank and the backwash water inlet; the backwash element and the backwash water inlet are coaxially arranged and located inside the high gradient magnetic field structure 11, and are used to backwash the inside of the high gradient magnetic field.

[0053] When performing the backwashing operation, first turn off the power, start the backwashing pump, and spray the pure water in the anaerobic concentration tank of the flushing water through the backwashing element and the backwashing water inlet to the steel wool 1121, and repeatedly flush the magnetic seed particles intercepted by the steel wool 1121 and the flocs attached to the steel wool 1121. After a period of sedimentation, they are discharged into the backwashing anaerobic digestion water tank through the floc outlet.

[0054] Furthermore, a plurality of pressure nozzles are distributed on the backwash element.

[0055] It can be understood that the plurality of pressure nozzles on the backwash element can be staggered along the axial and radial directions to perform all-round flushing in the separation channel 112 , and a smaller flow diameter can be used to generate a higher flow rate, thereby flushing the separation channel 112 more thoroughly.

[0056] Further, the backwash element is rotatably connected to the backwash water inlet so as to rotate freely under the impact of the water flow.

[0057] The backwash element can be rotatably connected to the inlet of the flushing water, and a baffle can be circumferentially arranged inside the backwash element. Under the impact of the water flow, the backwash element can be rotated to further enhance the comprehensiveness of the flushing.

[0058] However, the impurities such as floccules discharged through the floccules outlet are not only attached with a large number of flocculent magnetic species but also with many harmful bacteria, organic pollutants, etc. Therefore, it is necessary to further disinfect the floccules. Therefore, a sludge concentration anaerobic reactor 20 can be connected to the floccules outlet to further purify the floccules. The floccules undergo anaerobic degradation reaction in the sludge concentration anaerobic reactor 20, effectively decomposing the organic pollutants in the floccules and converting the inorganic pollutants. And the magnetic species become divalent iron ions with strong oxidizing effect under the action of anaerobic reaction, so that the magnetic species loses its magnetism and the floccules lose various strong forces, which are very easy to separate, thereby realizing efficient recovery of the magnetic species; and the subsequent floccules treatment only needs to be dehydrated, and the dehydrated water is basically pure water. Since the floccules contain nitrogen, phosphorus, potassium and other elements that are beneficial to farmland, the floc cakes can be used for returning to the field for fertilization.

[0059] Specific, combined with reference Figure 2 As shown, the sludge concentration anaerobic reactor 20 includes a shell 21, an anode 22, a cathode 23 and a power supply 24. A floc inlet 211 is provided on the top of the shell 21, and the floc inlet 211 is connected to the sewage discharge channel. A floc discharge port 212 is provided on the bottom of the shell 21; the anodes 22 are staggered and stacked inside the shell 21 to form an anode 22 area, and gaps are formed between the anodes 22 and the inner wall of the shell 21 for the flocs to pass through. The gaps of two adjacent anodes 22 are staggered to allow the flocs to pass through each anode 22 in turn; the cathode 23 is arranged in the shell 21 and is located at the periphery of the anode 22 area; the anode 22 and the cathode 23 are electrically connected to the positive and negative poles of the power supply 24 respectively.

[0060] When powered on, a large amount of strong oxidants such as hydroxyl radicals and hydrogen peroxide are generated around the anode 22 and the cathode 23, which strongly degrade the pollutants in the magnetic flocs. In addition, multiple layers of anodes 22 are arranged alternately, so that the flocs pass through the multiple layers of anodes 22 in sequence, further enhancing the disinfection capability.

[0061] In order to increase the electrochemical reaction rate, the anode 22 region is filled with a catalyst.

[0062] Furthermore, a sewage discharge channel is provided at the connection between the sludge concentration anaerobic reactor 20 and the floccules outlet, and a scraping member is provided in the sewage discharge channel for scraping off the floccules attached to the inner wall of the sewage discharge channel.

[0063] It can be understood that the sludge concentration anaerobic reactor 20 needs to be connected through a sewage channel, and the flocs may adhere to the inner wall of the sewage channel when passing through the sewage channel, and the flocs cannot be completely disinfected, which may cause secondary pollution to the purified solution. Therefore, a scraping and cleaning part can be set in the sewage channel, which can be a structure similar to a spiral push rod to actively push the flocs into the sludge concentration anaerobic reactor 20.

[0064] In one embodiment of the present application, the scraping member includes a frame, a vane and a driving member, the frame is penetrated inside the sewage channel; the vane is circumferentially arranged on the outer wall of the frame, and at least partially abuts against the inner wall of the sewage channel; the driving member is drivingly connected to the frame to drive the vane to rotate and scrape the inner wall of the sewage channel.

[0065] It can be understood that the vane can be a spirally extended sheet structure, and at least partially abuts against the inner wall surface of the sewage channel. The skeleton can be a cylindrical structure, and the vanes are arranged circumferentially along its outer wall. The driving member can be a motor, which is arranged on the outside of the sewage channel. The skeleton can be driven by connecting members such as belts, chains, and gears to make the vanes rotate inside the sewage channel to achieve scraping of the inner wall surface of the sewage channel.

[0066] The flocs purified by the sludge concentration anaerobic reactor 20 are basically non-toxic and harmless, and can be dehydrated by a centrifugal pump. The dehydrated water is basically pure water, and the floc cakes can be recycled and reused.

[0067] However, in order to further enhance the purification effect, the water discharged by the centrifugal pump may still contain bacteria that have not been completely sterilized, so the discharged water can be sterilized for a second time, and a secondary high-gradient magnetic field structure 11 can be set to re-process the discharged water. The specific structure of the secondary high-gradient magnetic field structure 11 refers to the above-mentioned high-gradient magnetic field structure 11, and will not be repeated here.

[0068] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
