Description

Technical Field

[0001] This utility model relates to the field of burners, specifically to an oxygen-enriched burner structure. Background Technology

[0002] A burner is a general term for a device that sprays fuel and air in a specific manner for combustion. Burners are classified into several types based on their application: industrial burners, combustion engines, civil burners, and special burners. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium. The function of a burner is to atomize a sample through flame combustion. The atomized sample enters the burner, and under the influence of the flame temperature and atmosphere, undergoes processes such as drying, melting, evaporation, and dissociation, producing a large number of ground-state atoms, as well as some excited-state atoms, ions, and molecules.

[0003] Most existing burners use air-assisted combustion. Since air contains only about 21% oxygen, a large amount of nitrogen participates in the combustion process. This not only absorbs heat, limiting the combustion temperature, but also produces pollutants such as nitrogen oxides, increasing the cost of subsequent environmental treatment.

[0004] Therefore, it is very necessary to provide an oxygen-enriched burner structure to solve the above-mentioned technical problems. Utility Model Content

An oxygen-enriching component is connected to the nozzle. The oxygen-enriching component includes a rotating sleeve rotatably connected to the nozzle and an oxygen-enriching drive connected to the rotating sleeve.

[0009] Furthermore, at least one oxygen inlet is connected to the nozzle guide ring, and a pneumatic valve is connected to the oxygen inlet.

[0010] Furthermore, it also includes two rotating sealing rings, which are respectively located on both sides of the rotating sleeve. One side of the rotating sealing ring is slidably connected to the rotating sleeve, and the other side of the rotating sealing ring is slidably connected to the nozzle.

[0011] Furthermore, the nozzle is connected to a first limiting ring and a second limiting ring, the first limiting ring being located on one side of the rotating sleeve and the second limiting ring being located on the other side of the rotating sleeve.

[0012] Furthermore, a first limiting ring for the sleeve body is connected to one side of the rotating sleeve, and the first limiting ring for the sleeve body abuts against the first limiting ring for the tube body.

[0013] Furthermore, a second limiting ring is provided on the other side of the rotating sleeve, and a connecting screw is connected to the second limiting ring. The connecting screw passes through the second limiting ring and is threadedly connected to the rotating sleeve. The connecting screw is used to fix the second limiting ring on the rotating sleeve.

[0014] Furthermore, the oxygenation drive includes a rotating sleeve with a sleeve gear connected to it, a drive gear connected to the sleeve gear, a drive motor connected to the drive gear, and the drive motor fixed to the nozzle.

[0015] Furthermore, a nozzle is connected to the nozzle pipe.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] The oxygen-enriching component is connected to the nozzle, and the oxygen-enriching drive rotates the rotating sleeve, precisely pumping external oxygen into the nozzle. This design significantly increases the oxygen concentration in the combustion zone, ensuring thorough mixing of fuel and oxygen, resulting in a more intense and rapid combustion reaction. The oxygen-enriching drive can flexibly adjust the rotation speed of the rotating sleeve according to actual combustion needs, thereby precisely controlling the amount of oxygen pumped into the nozzle. Under different operating conditions such as changes in combustion load and fuel type, it ensures that the burner receives the appropriate oxygen supply. This precise oxygen supply regulation capability guarantees the stability and efficiency of the combustion process, avoiding problems such as unstable combustion and flame extinction caused by improper oxygen supply, thus improving production safety and reliability. This design addresses the problem of existing technologies using air-assisted combustion, where air contains only about 21% oxygen, and a large amount of nitrogen participates in the combustion process.

[0042] like Figures 1 to 8As shown, an oxygen-enriched burner structure includes a burner body 1 and a nozzle 2 connected to the jet end of the burner body 1. An oxygen-enriching component 3 is connected to the nozzle 2. The oxygen-enriching component 3 includes a rotating sleeve 31 rotatably connected to the nozzle 2 and an oxygen-enriching drive 32 connected to the rotating sleeve 31. The oxygen-enriching drive 32 is used to drive the rotating sleeve 31 to pump external oxygen into the nozzle 2.

[0043] In this embodiment, the oxygen-enriching component 3 is connected to the nozzle 2, and the oxygen-enriching drive 32 drives the rotating sleeve 31 to rotate, precisely pumping external oxygen into the nozzle 2. This design significantly increases the oxygen concentration in the combustion zone, allowing the fuel and oxygen to mix thoroughly, resulting in a more intense and rapid combustion reaction. The oxygen-enriching drive 32 can flexibly adjust the rotation speed of the rotating sleeve 31 according to actual combustion needs, thereby precisely controlling the amount of oxygen pumped into the nozzle 2. Under different operating conditions such as changes in combustion load and fuel type, it can ensure that the burner receives just the right amount of oxygen. This precise oxygen supply regulation capability ensures the stability and efficiency of the combustion process, avoiding problems such as unstable combustion and flame extinction caused by improper oxygen supply, thus improving the safety and reliability of production. In addition, the burner body 1 of this application adopts a conventional burner available on the market, which is a technical means commonly used by those skilled in the art, and will not be described in detail here.

[0044] In some embodiments, an oxygen guide ring 311 is connected to the rotating sleeve 31, and a plurality of nozzle holes 21 are opened on the nozzle 2. The rotating sleeve 31 is disposed on the nozzle holes 21, and the oxygen guide ring 311 is used to introduce oxygen into the nozzle 2 through the nozzle holes 21.

[0045] In this embodiment, an oxygen guide ring 311 is provided on the rotating sleeve 31, and several nozzle holes 21 are opened on the nozzle 2, with the rotating sleeve 31 positioned on the nozzle holes 21. The oxygen guide ring 311 can precisely guide external oxygen into the nozzle 2 through the nozzle holes 21, allowing oxygen to enter the combustion zone in a more concentrated and efficient manner. This precise oxygen supply method greatly improves the mixing degree of oxygen and fuel, making the combustion reaction more complete and intense, significantly improving combustion efficiency, reducing fuel waste, and saving production costs for enterprises. The design of the oxygen guide ring 311, in conjunction with the nozzle holes 21, creates a specific airflow distribution when oxygen enters the nozzle 2. This optimized airflow distribution can better mix with the fuel, avoiding situations where the local oxygen concentration is too high or too low, thereby enhancing flame stability. During combustion, the flame can maintain a uniform and stable shape, reducing the occurrence of unstable phenomena such as flame flickering and extinguishing, and improving the safety and reliability of the combustion process.

[0046] In some embodiments, a nozzle guide ring 22 is connected to one side of the nozzle 2, and the rotating sleeve 31 is rotatably connected to the nozzle guide ring 22.

[0047] In this embodiment, a nozzle guide ring 22 is connected to one side of the nozzle 2, and a rotating sleeve 31 is rotatably connected to the nozzle guide ring 22. This design provides stable support and guidance for the rotating sleeve 31. During rotation, the nozzle guide ring 22 effectively restricts the radial and axial displacement of the rotating sleeve 31, ensuring that it rotates smoothly along a predetermined trajectory. In this way, the oxygen guide ring 311 can always guide oxygen into the nozzle 2 through the nozzle orifice 21 at a precise angle and position, ensuring the accuracy of oxygen supply. This, in turn, guarantees sufficient mixing of fuel and oxygen and efficient combustion, reducing oxygen supply deviation and combustion efficiency reduction caused by unstable rotation. The presence of the nozzle guide ring 22 reduces direct friction and wear between the rotating sleeve 31 and the nozzle 2. The smooth rotation of the rotating sleeve 31 on the nozzle guide ring 22 reduces motion resistance, thereby reducing the power required for the oxygenation drive 32 and lowering energy consumption. Meanwhile, due to reduced wear, the service life of related components such as the rotating sleeve 31, nozzle guide ring 22, and nozzle 2 is significantly extended, reducing the frequency of equipment maintenance and replacement, lowering the company's equipment maintenance costs and downtime, and improving production efficiency.

[0048] In some embodiments, at least one oxygen inlet end 4 is connected to the nozzle guide ring 22, and a pneumatic valve 5 is connected to the oxygen inlet end 4.

[0049] In this embodiment, at least one oxygen inlet end 4 is connected to the nozzle guide ring 22, and a pneumatic valve 5 is connected to the oxygen inlet end 4, enabling precise control of the oxygen supply. By adjusting the opening of the pneumatic valve 5, the oxygen flow rate entering the nozzle 2 can be precisely controlled to meet the oxygen supply requirements under different combustion conditions. When the combustion load changes, fuel type is switched, or the combustion stage is adjusted, the oxygen supply can be quickly and accurately adjusted to ensure that combustion is always in the optimal state, improving the flexibility and response speed of combustion adjustment. At the same time, an oxygen concentration sensor is connected inside the rotating sleeve 31 to achieve precise oxygen supply control, which helps to optimize the combustion process, ensuring that the fuel and oxygen are fully mixed and completely burned. The pneumatic valve 5 can adjust the oxygen intake in real time according to the actual combustion situation, avoiding incomplete combustion and energy loss due to insufficient oxygen supply, while also avoiding oxygen waste caused by excessive oxygen supply. This optimized combustion method significantly improves combustion efficiency, reduces energy consumption, saves production costs for enterprises, and improves economic benefits.

[0050] In some embodiments, a rotating sealing ring 6 is also included. Two rotating sealing rings 6 are provided, and the two rotating sealing rings 6 are respectively provided on both sides of the rotating sleeve 31. One side of the rotating sealing ring 6 is slidably connected to the rotating sleeve 31, and the other side of the rotating sealing ring 6 is slidably connected to the nozzle 2.

[0051] In this embodiment, two rotating sealing rings 6 are respectively disposed on both sides of the rotating sleeve 31 and slidably connected to the rotating sleeve 31 and the nozzle 2, forming a reliable sealing structure. This design effectively prevents oxygen leakage in the gap between the rotating sleeve 31 and the nozzle 2, ensuring that all external oxygen can be accurately introduced into the nozzle 2 through the oxygen guide ring 311 and the nozzle hole 21, significantly improving oxygen supply efficiency. Simultaneously, it avoids potential safety hazards caused by oxygen leakage, such as the risk of explosion due to oxygen accumulation, providing a higher level of safety for the production process. The rotating sealing rings 6 not only prevent oxygen leakage but also prevent external air, dust, and other impurities from entering the nozzle 2. If these impurities enter the combustion zone, they may interfere with the mixing process of fuel and oxygen, affecting the stability and efficiency of combustion, and even causing wear and damage to internal burner components. The presence of the rotating sealing rings 6 effectively maintains a clean environment inside the combustion system, ensuring stable burner operation and extending equipment lifespan. The rotating sealing rings 6, made of special materials and designed, provide good lubrication performance and reduce the coefficient of friction when slidably connected to the rotating sleeve 31 and the nozzle 2. This reduces frictional loss between the rotating sleeve 31 and the nozzle 2 during rotation, thus reducing component wear. In the long run, this helps extend the service life of the rotating sleeve 31, nozzle 2, and related transmission components, reducing equipment maintenance and replacement costs and improving equipment reliability and economy. Furthermore, the rotating sealing ring 6 can be replaced after a certain period of use.

[0052] In some embodiments, the nozzle 2 is connected to a first limiting ring 23 and a second limiting ring 24. The first limiting ring 23 is located on one side of the rotating sleeve 31, and the second limiting ring 24 is located on the other side of the rotating sleeve 31.

[0053] In this embodiment, a first limiting ring 23 and a second limiting ring 24 are connected to the nozzle 2, respectively located on both sides of the rotating sleeve 31, providing a clear axial positioning for the rotating sleeve 31. During installation and use, the rotating sleeve 31 is confined between the two limiting rings and can only rotate within its set axial range, preventing axial offset or movement. This precise positioning ensures the relative position stability between the rotating sleeve 31 and components such as the nozzle 2 and the oxygen guide ring 311, ensuring that oxygen can be accurately introduced into the nozzle 2 through the nozzle hole 21, maintaining the stable operation of the burner's oxygen supply system. The first limiting ring 23 and the second limiting ring 24 are tightly connected to the nozzle 2, enhancing the overall structural strength of the nozzle 2. During the rotation of the rotating sleeve 31 and the operation of the burner, the limiting rings can withstand certain axial and radial forces, preventing the nozzle 2 from deforming or being damaged due to stress. This helps improve the reliability of the burner equipment, reduces downtime and failures caused by structural damage, and ensures the continuity and stability of production. The first limiting ring 23 and the second limiting ring 24 of the pipe body also serve to protect rotating components such as the rotating sleeve 31. They prevent external debris from entering the gap between the rotating sleeve 31 and the nozzle 2, avoiding wear and jamming of the rotating components. At the same time, the limiting rings can disperse some of the stress generated during rotation, reducing the stress concentration on the rotating components, thereby extending the service life of the rotating sleeve 31 and related rotating components, and reducing the maintenance cost of the equipment.

[0054] In some embodiments, a first limiting ring 35 of the sleeve body is connected to one side of the rotating sleeve 31, and the first limiting ring 35 of the sleeve body abuts against the first limiting ring 23 of the tube body.

[0055] In this embodiment, the first limiting ring 35 of the sleeve body connected to one side of the rotating sleeve 31 abuts against the first limiting ring 23 of the tube body. This design further enhances the axial positioning accuracy of the rotating sleeve 31. During burner operation, the rotating sleeve 31 is subjected to various forces, such as centrifugal force during rotation and pressure generated by oxygen flow. The abutment between the first limiting ring 35 of the sleeve body and the first limiting ring 23 of the tube body effectively prevents the rotating sleeve 31 from moving accidentally in the axial direction, ensuring that it always remains in a precise position. This guarantees the accurate relative position of the oxygen guide ring 311 and the nozzle orifice 21, allowing oxygen to be stably and accurately introduced into the nozzle 2, maintaining the stable operation of the oxygen supply system. The abutment between the first limiting ring 35 of the sleeve body and the first limiting ring 23 of the tube body makes the fit between the rotating sleeve 31 and the nozzle 2 tighter. This tight fit reduces the gap between components, reducing energy loss caused by gas leakage or loose components. For example, it reduces oxygen leakage at the gaps, improving oxygen utilization; at the same time, it avoids additional friction and vibration caused by loose parts, reducing mechanical energy loss and further improving the overall efficiency of the burner.

[0056] In some embodiments, the other side of the rotating sleeve 31 is provided with a second limiting ring 33, and a connecting screw 34 is connected to the second limiting ring 33. The connecting screw 34 passes through the second limiting ring 33 and is threadedly connected to the rotating sleeve 31. The connecting screw 34 is used to fix the second limiting ring 33 on the rotating sleeve 31.

[0057] In this embodiment, the second limiting ring 33 of the sleeve is threadedly connected to the rotating sleeve 31 via a connecting screw 34. This adjustable fixing method allows the axial position of the second limiting ring 33 on the rotating sleeve 31 to be flexibly adjusted according to actual needs. When facing different combustion conditions, fuel types, or equipment operating parameters, technicians can precisely change the position of the second limiting ring 33 by rotating the connecting screw 34, thereby optimizing the axial limiting range of the rotating sleeve 31, ensuring the stability of oxygen supply and combustion process, and greatly improving the burner's adaptability to various operating conditions. The connecting screw 34 firmly fixes the second limiting ring 33 of the sleeve to the rotating sleeve 31, enhancing the stability of the entire rotating sleeve 31 structure. When the burner operates at high speed or is subjected to a large load, the second limiting ring 33 of the sleeve will not loosen or shift due to vibration or external force, effectively avoiding the problem of axial movement of the rotating sleeve 31 caused by limiting failure. This stability ensures the accurate relative position of the oxygen guide ring 311 and the nozzle orifice 21, ensuring that oxygen can be continuously and stably introduced into the nozzle 2, thus improving the reliability and operational safety of the equipment.

[0058] In some embodiments, the oxygenation drive 32 includes a rotating sleeve 31 with a sleeve gear 321 connected to it, a drive gear 322 connected to the sleeve gear 321, a drive motor 323 connected to the drive gear 322, and the drive motor 323 fixed to the nozzle 2.

[0059] In this embodiment, the rotational motion of the drive motor 323 can be stably and accurately transmitted to the rotating sleeve 31 through the gear connection between the sleeve gear 321 and the drive gear 322. This transmission method has high transmission accuracy and stability, ensuring that the rotating sleeve 31 rotates at a preset speed and angle, thereby precisely adjusting the relative position of the oxygen guide ring 311 and the nozzle orifice 21, achieving precise control of oxygen supply and distribution, meeting the oxygen supply requirements under different combustion conditions, and improving combustion efficiency and stability. The drive motor 323 is directly fixed to the nozzle 2 and adopts a gear transmission structure, making the overall structure of the oxygenation drive 32 compact. This compact design reduces the space occupied by the equipment, making it easy to lay out and install in various complex industrial environments, especially suitable for places with limited space, improving the applicability and installation flexibility of the equipment.

[0060] In some embodiments, a nozzle 7 is connected to the nozzle 2.

[0061] Example 1:

[0062] The nozzle 2 is installed at the jet end of the burner body 1. A secure connection can be ensured through welding, threaded connections, or other methods to prevent gas leakage. Simultaneously, the nozzle 2 is made of heat-insulating material. First, the nozzle guide ring 22 is fixed to one side of the nozzle 2; the fixing method can be welding or bolting.

[0063] Then, the rotating sleeve 31 is rotatably connected to the nozzle guide ring 22, for example, by using a bearing connection, so that the rotating sleeve 31 can rotate flexibly relative to the nozzle guide ring 22. An oxygen guide ring 311 is installed on the rotating sleeve 31, and can be secured by clips, bolts, or other means to ensure a tight connection between the oxygen guide ring 311 and the rotating sleeve 31. Simultaneously, it must be ensured that the rotating sleeve 31 is correctly fitted onto the nozzle hole 21 of the nozzle 2, so that the oxygen guide ring 311 corresponds to the nozzle hole 21. The oxygen guide ring 311 is installed on the rotating sleeve 31, and can be secured by clips, bolts, or other means to ensure a tight connection between the oxygen guide ring 311 and the rotating sleeve 31. Simultaneously, it must be ensured that the rotating sleeve 31 is correctly fitted onto the nozzle hole 21 of the nozzle 2, so that the oxygen guide ring 311 corresponds to the nozzle hole 21.

[0064] Furthermore, an oxygen inlet 4 is connected to the nozzle guide ring 22. The connection method can be a threaded connection or a flange connection to ensure sealing. A pneumatic valve 5 is installed on the oxygen inlet 4 to control the oxygen supply and flow rate.

[0065] Meanwhile, two rotating sealing rings 6 are placed on both sides of the rotating sleeve 31, so that one side of the rotating sealing ring 6 slides in contact with the rotating sleeve 31 and the other side slides in contact with the nozzle 2, which plays a sealing role and prevents oxygen leakage. The rotating sealing ring 6 can be fixed by a structure such as a sealing ring groove.

[0066] Finally, a first limiting ring 23 and a second limiting ring 24 are installed on the nozzle 2, located on both sides of the rotating sleeve 31, to restrict the axial movement of the rotating sleeve 31. A first limiting ring 35 is installed on one side of the rotating sleeve 31, abutting against the first limiting ring 23 to further enhance the limiting effect. A second limiting ring 33 is installed on the other side of the rotating sleeve 31, and is fixed to the rotating sleeve 31 by a connecting screw 34. The connecting screw 34 passes through the second limiting ring 33 and is threadedly connected to the rotating sleeve 31. Tightening the connecting screw 34 achieves fixation. A nozzle 7 is connected to the end of the nozzle 2, which can be achieved by threaded connection or welding, allowing the combusted gas to be ejected from the nozzle 7.

[0067] The specific implementation method of this application is as follows:

[0068] Check that all connections are secure and ensure that the pneumatic valve 5 is closed to prevent oxygen leakage. Connect the burner body 1 to the corresponding fuel supply system to ensure that fuel can be smoothly delivered into the burner body 1. Turn on the power to the drive motor 323 and check that it is working properly. Open the pneumatic valve 5, and external oxygen enters through the oxygen inlet 4. Then, start the drive motor 323, which drives the drive gear 322 to rotate. The drive gear 322 drives the sleeve gear 321 through gear transmission, thereby causing the rotating sleeve 31 to rotate on the nozzle guide ring 22. During rotation, the oxygen guide ring 311 on the rotating sleeve 31 guides the externally entering oxygen into the nozzle 2 through the nozzle hole 21 on the nozzle 2.

[0069] The nozzle 2 mixes the combustion-produced gas with the introduced oxygen. The mixed gas is delivered through the nozzle 2 to the nozzle 7 and ejected from the nozzle 7 for specific applications such as heating, welding, and cutting. According to actual needs, the oxygen intake is controlled by adjusting the opening of the pneumatic valve 5, thereby adjusting the oxygen ratio in the mixed gas and optimizing the combustion effect. The rotation speed of the rotating sleeve 31 can be changed by controlling the rotation speed of the drive motor 323, thus adjusting the rate at which oxygen is introduced into the nozzle 2. After use, first turn off the drive motor 323 to stop the oxygen-enriching drive 32. Then close the pneumatic valve 5 to cut off the oxygen supply. Finally, turn off the fuel supply to the burner body 1 to stop the burner from working.

[0070] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0071] The oxygen-enriching component is connected to the nozzle, and the oxygen-enriching drive rotates the rotating sleeve, precisely pumping external oxygen into the nozzle. This design significantly increases the oxygen concentration in the combustion zone, ensuring thorough mixing of fuel and oxygen, resulting in a more intense and rapid combustion reaction. The oxygen-enriching drive can flexibly adjust the rotation speed of the rotating sleeve according to actual combustion needs, thereby precisely controlling the amount of oxygen pumped into the nozzle. Under different operating conditions such as changes in combustion load and fuel type, it ensures that the burner receives the appropriate oxygen supply. This precise oxygen supply regulation capability guarantees the stability and efficiency of the combustion process, avoiding problems such as unstable combustion and flame extinction caused by improper oxygen supply, thus improving production safety and reliability. This design addresses the problem of existing technologies using air-assisted combustion, where air contains only about 21% oxygen, and a large amount of nitrogen participates in the combustion process. This not only absorbs heat, limiting the combustion temperature, but also produces pollutants such as nitrogen oxides, increasing subsequent environmental treatment costs.
