Description

Technical Field

[0001] This utility model relates to the field of combustion technology, specifically to a large-displacement side-burning ground-enclosed flare. Background Technology

[0002] In industrial production processes, large amounts of combustible waste gas are generated in many situations, such as in the petrochemical, coal chemical, and natural gas extraction industries. If these waste gases are directly discharged into the atmosphere, they will not only cause serious environmental pollution but also pose significant safety hazards. Large-capacity side-burning ground-enclosed flares, as a type of equipment specifically designed to treat these combustible waste gases, can efficiently burn the waste gases in a closed space, converting them into harmless substances such as carbon dioxide and water, thereby achieving the dual goals of environmental protection and safety. It features large processing capacity, high combustion efficiency, and good safety, playing an important role in modern industry.

[0003] In actual operation, the gas discharge of a large-displacement flare is not constant but fluctuates within a certain range. For example, in chemical production, different production stages or the start-up and shutdown of equipment will cause changes in the amount of gas emitted. When the gas discharge is small, if the air inlet area is too large, too much air will enter, causing the temperature in the combustion chamber to drop, affecting combustion efficiency, and even potentially causing flameout. If the air inlet area is too small, the air supply will be insufficient, preventing the gas from burning completely and reducing combustion efficiency. Therefore, a large-displacement side-burning ground-sealed flare is proposed. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a large-displacement side-burning ground-sealed flare, comprising a flare body, an air inlet at the bottom of the flare body, an exhaust outlet at the top of the flare body, a main air inlet pipe on the right side of the flare body, a graded branch pipe on the right side of the flare body, a burner connected to the graded branch pipe inside the flare body, and an airflow regulating mechanism at the top of the air inlet.

[0005] The airflow regulating mechanism includes a support frame. Support frames are provided on both the left and right sides of the air inlet. A bidirectional threaded rod is rotatably installed between the inner sides of the two support frames. A fixed rod is fixedly installed between the two support frames. Two movable blocks are threadedly installed on the outer surface of the bidirectional threaded rod. Two movable blocks are movably installed between the outer surfaces of the bidirectional threaded rod and the fixed rod. A closing plate is fixedly installed on the top of each of the two movable blocks. A motor is fixedly installed at the bottom of the left support frame. A worm gear is fixedly installed at the output shaft of the motor. A worm wheel is threadedly connected to the outer surface of the bidirectional threaded rod.

[0006] Furthermore, the worm and worm wheel mesh with each other, and both moving blocks are threadedly connected to the bidirectional threaded rod and slidably connected to the fixed rod.

[0007] Furthermore, both of the aforementioned sealing plates are fitted to the bottom of the air inlet, and the total diameter of the two sealing plates is equal to the diameter of the air inlet.

[0008] Furthermore, both of the support frames have openings inside that are adapted to the closed plate.

[0009] Furthermore, a gas flow sensor is provided at the top of the intake manifold, and the probe of the gas flow sensor extends into the interior of the intake manifold.

[0011] Furthermore, it also includes an external PLC controller, and the gas flow sensor, flame sensor and motor are electrically connected to the external PLC controller.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This large-displacement side-burning ground-sealed flare uses an airflow regulation mechanism to adjust the air inlet area in real time according to the exhaust gas flow rate, ensuring an appropriate air-to-exhaust gas ratio. This greatly improves combustion efficiency and avoids problems such as excessive air causing a drop in combustion chamber temperature that affects combustion, or insufficient air causing incomplete combustion of the gas.

[0014] 2. This large-capacity side-burning ground-enclosed flare features a gas flow sensor, flame sensor, and motor electrically connected to an external PLC controller, forming an automated control system. This eliminates the need for frequent manual intervention.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 In this embodiment, a large-displacement side-burning ground-sealed flare includes a flare body 1, an air inlet 2 at the bottom of the flare body 1, an exhaust port 3 at the top of the flare body 1, an air intake main pipe 4 on the right side of the flare body 1, a graded branch pipe 10 on the right side of the flare body 1, a burner 5 connected to the graded branch pipe 10 inside the flare body 1, and an airflow regulating mechanism 8 at the top of the air inlet 2.

[0021] The air volume regulating mechanism 8 includes a support frame 801. Support frames 801 are provided on both the left and right sides of the air inlet 2. A bidirectional threaded rod 802 is rotatably installed between the inner sides of the two support frames 801. A fixed rod 803 is fixedly installed between the two support frames 801. Two moving blocks 804 are threadedly installed on the outer surface of the bidirectional threaded rod 802. Two moving blocks 804 are movably installed between the outer surfaces of the bidirectional threaded rod 802 and the fixed rod 803. A closing plate 805 is fixedly installed on the top of each of the two moving blocks 804. A motor 806 is fixedly installed at the bottom of the left support frame 801. A worm gear 807 is fixedly installed at the output shaft of the motor 806. A worm wheel 808 is threadedly connected to the outer surface of the bidirectional threaded rod 802.

[0022] The flare body 1, as the main structure of the entire enclosed flare, provides a closed space for the combustion of waste gas, preventing the overflow of waste gas and flames generated during the combustion process, ensuring the safety and environmental protection of the combustion process, and preventing pollution and safety hazards to the surrounding environment. The air inlet 2 provides the necessary air for the combustion process inside the flare body 1. Air is an indispensable element in the combustion reaction. A sufficient air supply can ensure the complete combustion of the fuel gas, improve combustion efficiency, and convert the waste gas into harmless substances such as carbon dioxide and water as completely as possible. The exhaust port 3 is used to discharge the waste gas after combustion. After being fully burned by the burner 5, the waste gas is discharged into the atmosphere from the exhaust port 3. The main air inlet pipe 4 is responsible for transporting the combustible waste gas generated in industrial production to the burner 5 inside the flare body 1 through the branch pipes 10 for combustion treatment. It is the channel for waste gas to enter the flare, ensuring that the waste gas can reach the combustion area smoothly. The burner 5 is the core component of the flare. It mixes the combustible waste gas transported by the branch pipes 10 with the air entering through the air inlet 2 and ignites the mixture to achieve the combustion of the waste gas.

[0023] The intake manifold 4 receives flow from the gas flow sensor 6, which determines the flow rate of the gas entering the tiered branch pipe 10 to decide which stage to open for the flare body 1. The gas flow sensor 6 monitors the flow rate of combustible waste gas in the intake manifold 4 in real time. By accurately obtaining the waste gas flow information, it can provide a basis for subsequent air volume adjustment, thereby ensuring the stability and efficiency of the combustion process. The flame sensor 7 detects the flame status in the burner 5. When the flame is abnormal, such as flameout, the flame sensor 7 can send a signal in time to facilitate the implementation of corresponding measures to ensure the safety of the combustion process. The gas flow sensor 6, the flame sensor 7, and the motor 806 are all electrically connected to the external PLC controller 9. The PLC controller 9 controls the motor 806 based on the data from the former two components to precisely adjust the area of ​​the air inlet 2, thereby achieving automated and efficient operation of the system.

[0024] The worm gear 804 is rotated by the transmission action of the motor 806, worm 807 and worm wheel 808. The threads on its outer surface can make the two moving blocks 804 move towards or away from each other, thereby realizing the position adjustment of the sealing plate 805. The sealing plate 805 adjusts the opening size of the air inlet 2 by moving, thereby controlling the amount of air entering the torch body 1. When the sealing plates 805 are close to each other, the area of ​​the air inlet 2 decreases and the air volume decreases; when the sealing plates 805 are far apart, the area of ​​the air inlet 2 increases and the air volume increases.

[0025] Working principle: The gas flow sensor 6 monitors the exhaust gas flow in the intake manifold 4 in real time and transmits the data to the external PLC controller 9. Based on the received exhaust gas flow information and a preset program, the PLC controller 9 sends a command to the motor 806. The motor 806 rotates, driving the worm gear 807 on the output shaft to rotate. The worm gear 807 meshes with the worm wheel 808, driving the bidirectional threaded rod 802 to rotate. The threads on the outer surface of the bidirectional threaded rod 802 cause the two moving blocks 804 to move towards or away from each other along the fixed rod 803. The closing plate 805 on the top of the moving blocks 804 moves accordingly, thereby flexibly adjusting the opening size of the air inlet 2, achieving precise control of the amount of air entering the flare body 1, ensuring that the ratio of air to exhaust gas is always appropriate, and maintaining efficient combustion.

[0026] In summary, this large-displacement side-burning ground-sealed flare, through the air volume adjustment mechanism 8, adjusts the area of ​​the air inlet 2 in real time according to the exhaust gas flow rate, ensuring an appropriate air-to-exhaust gas ratio, greatly improving combustion efficiency, and avoiding the problems of excessive air causing a drop in combustion chamber temperature that affects combustion, or insufficient air causing incomplete combustion of the gas.

[0027] Furthermore, the gas flow sensor 6, flame sensor 7, and motor 806 are electrically connected to the external PLC controller 9 to form an automated control system. Without frequent manual intervention, the system can automatically adjust the air intake area based on real-time data to adapt to changes in exhaust gas discharge under different working conditions, thereby improving the stability and reliability of equipment operation, reducing labor costs and the risk of operational errors, and has important application value in modern industrial production.
