Description

Technical Field

[0001] This utility model relates to the field of torch burner technology, specifically a lifting-type micro-positive pressure maintaining energy-concentrating torch burner. Background Technology

[0002] A flare burner is a device used to treat combustible waste gases, exhaust gases, or emergency exhaust gases generated during industrial production processes. 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 the 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 to produce a large number of ground-state atoms, as well as some excited-state atoms, ions, and molecules. A well-designed burner should have high atomization efficiency, low noise, and stable flame performance to ensure high absorption sensitivity and measurement precision. In atomic absorption spectroscopy, slit burners are commonly used to generate atomic vapor. The length and width of the burner slit vary depending on the type of fuel gas and oxidizing gas used. Generally, the applicable fuel gas and oxidizing gas are marked on the burner.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. Without a micro-positive pressure automatic shut-off component for raising and lowering, the combustion state cannot be automatically adjusted according to actual needs. Combustion continues even when it is not needed, leading to unnecessary energy consumption. Furthermore, the lack of micro-positive pressure for stabilization causes the flame to become unstable during combustion, easily resulting in flame flickering, incomplete combustion, and other problems, affecting process quality and production efficiency. 2. The flare combustion port requires the input of natural gas, propane, hydrogen, and carbon monoxide. Without a one-way gas blocking component, the unidirectional flow of gas cannot be effectively controlled, leading to unstable flow phenomena such as backflow and turbulence at the gas inlet. This affects the stability and uniformity of combustion. The unstable gas flow results in uneven mixing and incomplete combustion during the combustion process, thus reducing combustion efficiency, wasting energy, and potentially producing more incomplete combustion products. Utility Model Content

[0004] The purpose of this invention is to provide a lifting-type micro-positive pressure maintaining energy-concentrating torch burner to solve the problem mentioned in the background art where the flame is easily affected by wind, causing flame flickering or incomplete combustion, thus affecting flame stability. To achieve the above objective, this invention provides the following technical solution: a lifting-type micro-positive pressure maintaining energy-concentrating torch burner, including a main torch tube, with a connecting tube welded above the main torch tube;

[0005] A temperature sensor is installed on the outer wall of the main flare tube by screws. A feed inlet is welded to one side of the main flare tube. A Tesla valve is welded inside the feed inlet. A safety valve is connected to the top of the feed inlet by threads. A pressure gauge and a regulating valve are connected to the top of the feed inlet by threads. A regulating valve is provided on one side of the pressure gauge.

[0006] The connecting cylinder has a discharge port inside, a buoyancy ball is attached above the discharge port, a support plate is welded above the connecting cylinder, and a limit plate is welded above the support plate.

[0007] More preferably, the connection between the connecting tube and the main torch tube forms a cylinder, and the middle part of the main torch tube is a truncated cone, that is, the diameter gradually decreases from the top to the bottom, the top circle is larger and the bottom circle is smaller, the side is smoothly inclined, connecting the upper and lower circles of different sizes, and the bottom of the main torch tube is a cylinder.

[0008] More preferably, the size of the buoyancy ball is larger than the size of the outlet hole above the connecting cylinder, and the interior of the connecting cylinder is provided with multiple sets of burners, with the outlets distributed in a ring around the center of the connecting cylinder.

[0009] More preferably, the support plate and the limiting plate are integrally connected, and the limiting plate is in the shape of an "X", and a support plate is provided at the lower corner of the limiting plate.

[0010] More preferably, a regulating valve, a pressure gauge, and a safety valve are arranged horizontally above the feed inlet.

[0011] More preferably, the feed inlet is equipped with a Tesla valve, and the Tesla valve has several branches. Each pipeline is divided into two branches, one of which is slightly inclined, and the other is bent into a semi-loop before returning to the inclined pipeline. Subsequent branches have the same structure.

[0012] More preferably, the external structural dimensions of one side of the feed inlet are consistent with the internal structural dimensions of the main flare tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, a slight positive pressure helps maintain stable combustion conditions, improving combustion quality and stability. A buoyancy ball is installed above the discharge port, which can automatically adjust according to pressure changes to adapt to different working conditions and load variations. When combustion is not required, the air pressure is shut off, and the buoyancy ball will move downward to block the discharge port, achieving automatic closure, reducing unnecessary fuel consumption and improving energy utilization efficiency. A safety valve is also provided, which can limit the pressure inside the burner to prevent excessive pressure from causing equipment damage, explosion, or other dangerous situations, ensuring the safe operation of the equipment.

[0015] In this invention, the unique structure of the Tesla valve allows for a certain degree of natural regulation of the intake airflow, making the intake airflow more stable and controllable. This helps improve the stability and uniformity of combustion, ensures unidirectional gas flow, reduces backflow and turbulence, and improves the efficiency and quality of the intake airflow. At the same time, compared with traditional valves, the Tesla valve may generate less pressure loss when allowing gas to pass in the forward direction, which helps maintain the intake air pressure, saves energy, and the more stable and optimized intake airflow helps the fuel and air mix more fully, thereby improving combustion efficiency and reducing incomplete combustion and pollutant emissions.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a lifting micro-positive pressure maintaining energy-concentrating torch burner, including a main torch tube 1, and a connecting tube 2 welded above the main torch tube 1;

[0024] A temperature sensor 101 is installed on the outer wall of the main flare tube 1 by screws. A feed inlet 105 is welded to one side of the main flare tube 1. A Tesla valve 106 is welded inside the feed inlet 105. A safety valve 102 is connected to the top of the feed inlet 105 by threads. A pressure gauge 103 and a regulating valve 104 are connected to the top of the feed inlet 105 by threads respectively. A regulating valve 104 is provided on one side of the pressure gauge 103.

[0025] The connecting cylinder 2 has an outlet 204 inside, a buoyancy ball 202 attached above the outlet 204, a support plate 203 welded above the connecting cylinder 2, and a limit plate 201 welded above the support plate 203.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the connection between the connecting tube 2 and the main torch tube 1 forms a cylinder, and the middle part of the main torch tube 1 is a truncated cone, that is, the diameter gradually decreases from the top to the bottom, the top circle is larger and the bottom circle is smaller, the side is smoothly inclined, connecting the upper and lower circles of different sizes, and the bottom of the main torch tube 1 is a cylinder; the design of the connecting tube 2 and the main torch tube 1 as a smooth box in the shape of an "ice cream cone" can reduce air resistance, and in windy environments, it can reduce the interference of wind on the torch combustion and keep the flame stable.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the size of the buoyancy ball 202 is larger than the opening size of the discharge port 204 above the connecting cylinder 2, and the connecting cylinder 2 is equipped with multiple sets of burners, with the discharge ports 204 distributed in a ring around the center of the connecting cylinder 2. The buoyancy ball 202 can float up and down according to changes in internal pressure and flow rate, thereby automatically adjusting the opening size of the discharge port 204 to achieve dynamic control of fuel or gas flow rate, making combustion more stable and efficient. In some cases, the buoyancy ball 202 can play a role in preventing backfire, reducing the risk of flame flowing back into the burner and improving safety. At the same time, it helps to balance the pressure inside and outside the injection port, avoiding the adverse effects of sudden pressure changes on the combustion process. It can also reduce unnecessary fuel or gas consumption by precisely controlling the flow rate, thereby achieving energy saving.

[0028] In this embodiment, as Figure 5 As shown, the support plate 203 and the limiting plate 201 are integrally connected, and the limiting plate 201 is in the shape of an "X". The lower corner of the limiting plate 201 is provided with a support plate 203. The "X" shape of the limiting plate 201 and the support plate 203 can restrict the buoyancy ball 202 from falling, and allow the buoyancy ball 202 to move and adjust its height in a fixed position.

[0029] In this embodiment, as Figure 4 As shown, a regulating valve 104, a pressure gauge 103, and a safety valve 102 are arranged horizontally above the feed inlet 105. The regulating valve 104 can precisely regulate the flow rate and speed of the feed to ensure that the burner receives the appropriate amount of fuel or gas, thereby achieving stable and efficient combustion. The pressure gauge 103 displays the pressure of the feed inlet 105 in real time, which allows operators to determine whether the system is operating normally. The safety valve 102 automatically opens when the pressure exceeds the set safety value to release the pressure, preventing damage or danger to the equipment due to excessive pressure and ensuring the safety of the entire combustion system. The temperature sensor 101 can monitor the temperature of the feed, which helps to detect abnormal temperature changes in advance, adjust the feed parameters in time, optimize the combustion process, and avoid adverse effects on the combustion effect and equipment due to excessively high or low temperatures.

[0030] In this embodiment, as Figure 4As shown, the feed inlet 105 is equipped with a Tesla valve 106, which has several branches. Each pipeline is divided into two branches, one of which is slightly inclined, and the other is bent into a semi-loop before returning to the inclined pipeline. Subsequent branches have the same structure. The split-flow Tesla valve 106 can ensure unidirectional flow of feed, effectively prevent backflow, and ensure the stability and reliability of the combustion process. For forward feed, the resistance it generates is relatively small, which helps fuel or gas to enter the burner more smoothly, improves feed efficiency, reduces pressure fluctuations during the feed process, makes the feed pressure more stable, and is conducive to optimizing combustion conditions. The split-flow Tesla valve 106 has no complex moving parts, has a relatively simple structure, is not prone to failure, and has low maintenance costs.

[0031] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the external structural dimensions of one side of the feed inlet 105 are consistent with the internal structural dimensions of the main flare tube 1; the feed inlet 105 has the same diameter as the main flare tube 1, which can stably transmit the internal airflow and facilitate the stable transmission of combustion gas.

[0032] The usage and advantages of this utility model: The working process of this lifting-type micro-positive pressure maintaining energy-concentrating torch burner is as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the flame burner is running, the regulating valve 104 is opened. The temperature and pressure inside the connecting cylinder 2 can be checked by the temperature sensor 101 and the pressure gauge 103. Since the main torch cylinder 1 is connected to the gas supply pipe of the connecting cylinder 2, the main torch cylinder 1 is always filled with fuel gas, which can be ignited immediately. The combustion gas flow above the discharge port 204 will cause the buoyancy ball 202 to rise. The buoyancy ball 202 can float up and down according to the changes in internal pressure and flow, thereby automatically adjusting the opening size of the discharge port 204, realizing dynamic control of fuel or gas flow, making the combustion more stable. The limit plate 201 restricts the buoyancy ball 202 from falling. The buoyancy ball 202 is provided above to concentrate the fire energy at a certain height and position, which can reduce the flame drifting in wind and rain. When the internal pressure of the main torch cylinder 1 exceeds the limit, the safety valve 102 will automatically shut off to avoid accidents.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
