Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to an energy-saving sewage treatment device based on electromagnetic shearing action. Background Art

[0002] At present, the equipment and facilities of traditional sewage treatment plants consume a lot of electricity during operation. For example, sewage lifting pumps and aeration devices are all high-energy consuming equipment. In addition, in order to meet the needs of sewage treatment processes, a large amount of chemical agents are often required to be added, which not only increases operating costs, but also may bring secondary pollution risks. At the same time, traditional processes are not effective in treating sewage containing heavy metals, difficult-to-degrade organic matter, etc., and it is difficult to meet emission standards.

[0003] As a new technology, electromagnetic field treatment of sewage has received extensive attention in recent years. It separates different substances in sewage through the effects of electrostatic field, magnetic field, electrochemical field, etc., to achieve the purpose of purifying sewage; however, the single electromagnetic field treatment technology still has some limitations in practical application, resulting in poor treatment effect. Summary of the invention

[0004] In order to improve the treatment effect, the present application provides an energy-saving sewage treatment device based on electromagnetic shear action.

[0005] The present application provides an energy-saving sewage treatment device based on electromagnetic shearing, which adopts the following technical solution:

[0006] An energy-saving sewage treatment device based on electromagnetic shearing action, comprising:

[0007] A water supply pipe, connected to the sewage source, for sewage supply;

[0008] a treatment pipe connected to an end of the water supply pipe away from the water source;

[0009] An electromagnetic shear field generator is arranged at the treatment pipe and is used to perform magnetic field intervention on the sewage in the treatment pipe;

[0010] A plurality of guide plates are provided, and the plurality of guide plates are evenly distributed and rotatably arranged in the processing tube;

[0011] A reaction tank connected to the water outlet end of the treatment pipe, and forming a reaction chamber for sewage reaction treatment inside;

[0012] an ozone generator, connected to the reaction tank, for supplying ozone to the reaction tank;

[0013] The sewage circulation pump is connected between the reaction tank and the water supply pipe to form sewage circulation and discharge the treated sewage.

[0014] By adopting the above technical solution, sewage is introduced into the treatment pipe from the sewage source through the water supply pipe. After the sewage enters the treatment pipe, it will encounter the electromagnetic shear field generator, which intervenes in the sewage by generating a magnetic field, and uses the electromagnetic force to produce a shear effect on suspended matter, colloids, dissolved matter, etc. in the sewage. This shear effect can destroy the stable structure of pollutants in the sewage, making it easier to be removed by subsequent treatment steps.

[0015] In the treatment pipe, the sewage flows along multiple evenly distributed guide plates and collides with the guide plates. The rotating guide plates can further promote the mixing and flow of sewage in the treatment pipe and enhance the treatment effect of the electromagnetic shear field on the sewage. At the same time, the rotation of the guide plates may also generate a certain shear force, which helps to decompose the macromolecular substances in the sewage.

[0016] The sewage after electromagnetic shear treatment enters the reaction tank, where it reacts with ozone. Ozone is a strong oxidant that can effectively oxidize and decompose organic and inorganic matter in the sewage, further purifying the water quality.

[0017] In order to improve the treatment efficiency, a sewage circulation pump is installed in the system. This pump draws part of the sewage in the reaction tank back to the water supply pipe to form a circulation treatment. Through multiple cycles, it can ensure that the sewage is fully treated and achieve the expected purification effect.

[0018] The above technical solution, through the setting of guide plates, electromagnetic shear field generators and sewage circulation pumps, allows the sewage to undergo multiple shear field treatments, so that suspended matter, colloids, heavy metals and other substances are dispersed multiple times, changing the cluster structure of water molecules, organic pollutant molecules and ion atmospheres in the sewage, and changing the physical, chemical, molecular mechanics and other properties of the treated sewage, making it more evenly dispersed, facilitating contact with ozone, increasing the ozone solubility capacity, improving the ozone catalytic oxidation efficiency, and improving the treatment effect.

[0019] Optionally, two electromagnetic shear field generators are provided, and the two electromagnetic shear field generators are arranged along the length direction of the treatment pipe. The magnetic fields formed by the two electromagnetic shear field generators have a certain angle, and cooperate with the guide plate to drive the sewage to rotate.

[0020] By adopting the above technical solution, when the sewage flows through the first electromagnetic shear field generator, it will be affected by the magnetic field, and the particles in the sewage will begin to be affected by the Lorentz force, but because there is only one magnetic field at this time, its effect may be relatively limited; however, when the sewage continues to flow and encounters the second electromagnetic shear field generator, due to the angle between the two magnetic fields, the particles in the sewage will be affected by forces in different directions, and this difference in force will cause the sewage to begin to rotate in the treatment pipe.

[0021] The guide plate installed in the treatment pipe not only enhances the mixing and flow of sewage, but also further promotes the rotation of sewage; the rotation design of the guide plate and the angle of the two magnetic fields work together to form a dynamic rotating flow field for sewage in the treatment pipe, so that suspended matter, colloids and heavy metals can be treated, facilitating subsequent contact with ozone, further increasing the ozone solubility capacity, improving the ozone catalytic oxidation efficiency, and improving the treatment effect.

[0022] When the two magnetic fields are in opposite directions and the particles move fast enough, oscillations can be formed, causing complex movements in the treatment tube. This can also speed up the treatment of suspended matter, colloids, and heavy metals, facilitate subsequent contact with ozone, further increase ozone solubility, improve ozone catalytic oxidation efficiency, and improve treatment effects.

[0023] Optionally, protrusions are provided between the guide plates, the height of the protrusions is lower than the height of the guide plates, and the ends of the protrusions form a smooth surface.

[0024] By adopting the above technical solution, the setting of the protrusions increases the collision between sewage, facilitates the dispersion of clumped substances, and at the same time can slow down the flow rate of sewage, prolonging the time of sewage in the electromagnetic shear field, increasing the treatment of suspended matter and other substances, further facilitating the subsequent decomposition of ozone, and improving the treatment effect.

[0025] Since the height of the protrusion is lower than the guide plate, the flow velocity of the sewage will change when it flows through the protrusion; especially at the end of the protrusion, due to its smooth shape, the sewage will encounter an area where the flow velocity suddenly changes, thereby generating turbulence. The turbulence helps to break the colloidal stability in the sewage and promote the separation of suspended matter from the sewage.

[0026] The setting of the protrusions also enhances the mixing effect of sewage in the treatment pipe. When sewage flows through the protrusions, it will be subjected to forces from different directions. The interaction of these forces makes the sewage more fully mixed in the treatment pipe. The enhanced mixing helps to increase the contact area and reaction efficiency of ozone and sewage.

[0027] The rounded raised end design helps reduce sedimentation during flow.

[0028] Optionally, a flow-blocking rod is provided in the treatment pipe, and the flow-blocking rod is connected to one end of the treatment pipe close to the water supply pipe through a connecting frame, and the flow-blocking rod and the inner wall of the treatment pipe form a channel for sewage to flow.

[0029] By adopting the above technical solution, when sewage enters the treatment pipe from the water supply pipe, it will first encounter the baffle rod. Due to the existence of the baffle rod, the sewage cannot flow directly through, but needs to bypass the channel formed by the baffle rod to continue moving forward, so that the sewage rotates in combination with the electromagnetic shear field, which is convenient for the separation of suspended matter and other substances from the sewage; when the sewage bypasses the baffle rod, its flow direction will change; this change helps to break the laminar flow state of the sewage, increase the turbulence of the sewage, and thus promote the separation of suspended matter in the sewage from the sewage; and the baffle rod cooperates with the guide plate and the electromagnetic shear field to increase the treatment time of suspended matter and other substances, further making the dispersion more uniform, which is convenient for the subsequent decomposition of ozone.

[0030] Optionally, a guide plate is integrally provided on the connecting frame, and the guide plate is arranged at an angle and is consistent with the inclination direction of the guide plate.

[0031] By adopting the above technical solution, when sewage enters the treatment pipe from the water supply pipe, it will first encounter the guide plate. The main function of the guide plate is to guide the flow direction of the sewage and form a certain flow state in the treatment pipe; then, the sewage will flow through the guide plate on the connecting frame. Since the guide plate is set at an angle and is consistent with the inclination direction of the guide plate, it further guides the sewage to ensure that the sewage can flow smoothly along the predetermined path; the setting of the guide plate also plays a role in pretreatment. In the process of sewage flowing through the guide plate, due to the change in flow rate and flow direction, the suspended matter in the sewage may be subjected to a certain centrifugal force, which helps to separate it from the sewage and improve the treatment effect of suspended matter and other substances.

[0032] Optionally, an air supply cavity is formed inside the baffle rod, and both ends of the baffle rod are closed. The air supply cavity is connected to the air outlet end of the ozone generator through a hose, and an air outlet hole is opened on the outer wall of the baffle rod, and the opening direction of the air outlet hole is opposite to the rotation direction of the sewage.

[0033] By adopting the above technical solution, the ozone generated by the ozone generator enters the air supply cavity inside the choke rod through the hose. Since both ends of the choke rod are closed, the ozone is confined in the air supply cavity and is ready to be released into the sewage through the air outlet.

[0034] The sewage is affected by the guide plate in the treatment pipe, forming a certain rotating flow state. This rotation helps to enhance the mixing effect of sewage and ozone.

[0035] When sewage flows through the blocking rod, since the opening direction of the air outlet is opposite to the direction of sewage rotation and at an obtuse angle, ozone will form a certain relative speed with the sewage when it is sprayed out from the air outlet; this relative speed helps ozone to be better dispersed into the sewage and increase its contact area with the sewage.

[0036] The ozone released into the sewage reacts with the organic matter in the sewage, oxidizing and decomposing the organic matter, thereby achieving the purpose of purifying the sewage. Since the inclination angle of the air outlet is smaller than the inclination angle of the guide plate, the release direction of the ozone forms a certain angle with the rotation direction of the sewage, which helps to further enhance the mixing effect of the sewage and ozone.

[0037] Optionally, a filter screen is provided on the air outlet, and the filter screen is close to the side wall of the processing tube and is flush with the outer surface of the blocking rod.

[0038] By adopting the above technical solution, the setting of the filter can reduce the debris in the sewage from entering the air outlet, and by setting the filter flush with the outer surface of the flow-blocking rod, the influence on the rotating flow of the sewage is reduced.

[0039] Optionally, a plurality of air supply holes are provided on the outer wall of the processing tube, and the air supply holes are arranged between two adjacent protrusions;

[0040] A plurality of air supply pipes are arranged on the processing pipe, the air supply pipes are connected with the air outlet end of the ozone generator, the air supply pipes correspond to the air supply holes and are provided with one-way valves, and a partition net is arranged at the one-way valve.

[0041] By adopting the above technical solution, the ozone generated by the ozone generator is transported to the inside of the treatment pipe through the air supply pipe; when the sewage in the treatment pipe flows, due to the design of the protrusions and the air supply holes, a certain negative pressure area will be formed in the sewage during the flow, thereby attracting the ozone in the air supply pipe to enter the treatment pipe through the air supply holes; the setting of the one-way valve ensures that ozone can only enter the treatment pipe from the air supply pipe and cannot flow in the opposite direction, which helps to prevent sewage or other impurities from entering the air supply pipe, thereby protecting the ozone generator from contamination.

[0042] The screen is set at the one-way valve to filter out impurities or particles in the sewage and reduce damage to the one-way valve.

[0043] The screen can also prevent ozone in the air supply pipe from directly impacting the air supply hole under high pressure, thereby protecting the air supply hole from being blocked or damaged.

[0044] The air replenishment hole is set between two adjacent protrusions. This design helps to form a more uniform negative pressure area during the flow of sewage, thereby ensuring that ozone can be evenly distributed to all parts of the treatment pipe; the design of the protrusion can also increase the turbulence of sewage in the treatment pipe, which helps to enhance the mixing effect of sewage and ozone; and at any time, the impact of sewage on the protrusion can be increased by setting an external power air pump, which facilitates the dispersion of suspended matter and further changes the cluster structure of water molecules, organic pollutant molecules, and ion atmospheres in sewage.

[0045] Optionally, the air supply hole is located toward a side of the protrusion close to the water supply pipe, and the opening angle is consistent with the inclination direction of the guide plate.

[0046] By adopting the above technical solution, since the opening angle of the air supply hole is consistent with the inclination direction of the guide plate, gases such as ozone can be introduced along the flow direction of sewage, reducing the relative speed difference between gas and sewage, thereby reducing energy consumption and gas loss.

[0047] The introduced gas and sewage form turbulence near the protrusions, which enhances the mixing effect. This turbulence not only helps ozone and other gases to be more evenly distributed in the sewage, but also increases the contact area and reaction rate between sewage and gas.

[0048] Through the synergistic effect of the air inlet holes, guide plates and protrusions, the flow state of sewage in the treatment pipe has been optimized; this optimization not only improves the utilization rate and treatment efficiency of gases such as ozone, but also reduces energy consumption and operating costs during the treatment process.

[0049] Optionally, the two electromagnetic shear field generators can rotate around the processing tube and rotate in opposite directions.

[0050] By adopting the above technical solution, when the electromagnetic shear field generators are started, they will generate a strong electromagnetic field inside the treatment pipe, which will exert shear force on the sewage flowing through, thereby changing the cluster structure of water molecules, organic molecules and ion atmospheres in the sewage.

[0051] At the same time, the two electromagnetic shear field generators begin to rotate around the treatment pipe and rotate in opposite directions; this rotational motion not only enhances the uniformity and coverage of the electromagnetic field, but also helps to form more complex flow patterns and turbulence in the sewage.

[0052] The sewage in the treatment pipe is affected by the combined effects of guide plates, protrusions and electromagnetic shear field generators, forming a specific flow pattern and velocity distribution.

[0053] As the electromagnetic shear field generator rotates, the molecules and ions in the sewage are subjected to constantly changing electromagnetic forces, thereby enhancing the mixing and collision frequency between them; this mixing and collision helps to accelerate the reaction rate of ozone and organic matter and improve treatment efficiency.

[0054] While the electromagnetic shear field generator rotates, gases such as ozone are introduced into the treatment pipe through the gas supply holes; these gases are more evenly distributed in the sewage under the action of the electromagnetic field; ozone and organic matter in the sewage undergo a rapid oxidation reaction under the action of the electromagnetic shear field, generating short-chain, easily degradable organic matter or directly oxidizing into carbon dioxide and water; this reaction not only improves the purification quality of sewage, but also reduces energy consumption and operating costs during the treatment process.

[0055] In summary, the present application includes at least one of the following beneficial technical effects:

[0056] 1. Through the setting of guide plate, electromagnetic shear field generator and sewage circulation pump, the sewage is treated by shear field for many times, so that suspended matter, colloid, heavy metals and other substances are dispersed for many times, the cluster structure of water molecules, organic pollutant molecules and ion atmosphere in sewage is changed, and the physical, chemical and molecular mechanical properties of the treated sewage are changed, making it more evenly dispersed, convenient for contact with ozone, increasing ozone solubility, improving ozone catalytic oxidation efficiency and improving treatment effect;

[0057] 2. The air filling hole is set between two adjacent protrusions. This design helps to form a more uniform negative pressure area during the flow of sewage, thereby ensuring that ozone can be evenly distributed to all parts of the treatment pipe; the protrusion design can also increase the turbulence of sewage in the treatment pipe, which helps to enhance the mixing effect of sewage and ozone; and at any time, the impact of sewage on the protrusion can be increased by setting an external power air pump, which is convenient for the dispersion of suspended matter and further changes the cluster structure of water molecules, organic pollutant molecules, and ion atmospheres in sewage;

[0058] 3. While the electromagnetic shear field generator is rotating, gases such as ozone are introduced into the treatment pipe through the air supply holes; these gases are more evenly distributed in the sewage under the action of the electromagnetic field; ozone and organic matter in the sewage undergo rapid oxidation reaction under the action of the electromagnetic shear field, generating short-chain, easily degradable organic matter or directly oxidizing into carbon dioxide and water; this reaction not only improves the purification quality of sewage, but also reduces energy consumption and operating costs during the treatment process.
