Description

Technical Field

[0001] This invention relates to the field of flare equipment, and in particular to a flare head with strong adaptability to venting volume. Background Technology

[0002] As a key safety and environmental protection device in industries such as petrochemicals, natural gas processing, oil refining, and energy extraction, the flare head is mainly used to ignite and fully combust combustible waste gases, emergency vented gases, or volatile organic compounds (VOCs) emitted during the process, thereby converting harmful substances into carbon dioxide and water, preventing them from being directly released into the atmosphere and causing pollution and safety hazards. In actual production, due to fluctuations in production conditions, equipment start-up and shutdown, maintenance and repair, or emergency response, the gas flow rate (i.e., venting volume) entering the flare system often varies within a wide range, potentially ranging from extremely low sporadic emissions to extremely high emergency venting volumes.

[0003] Traditional fixed-structure flare heads are typically optimized for a specific design flow rate, maintaining a stable flame shape and high combustion efficiency under design conditions. However, when the actual venting volume is far below the design value, the gas velocity at the flare head outlet is too low, potentially leading to flame instability, drift, or even flameout, resulting in the direct emission of unburned gas. Simultaneously, excessive air may be entrained into the flare tube, causing a decrease in combustion temperature, incomplete combustion, and even black smoke. Conversely, when the venting volume surges instantaneously beyond the design capacity, excessively high velocities may cause the flame to detach (blown off), resulting in noise, uneven heat radiation, and incomplete combustion. Summary of the Invention

[0004] In view of this, the present invention aims to provide a torch head with strong adaptability to venting volume in order to solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows: A flare head with strong adaptability to venting volume includes a flare distribution pipe, a combustion cylinder, and a connecting assembly, wherein the flare distribution pipe and the combustion cylinder are connected by the connecting assembly. The connecting assembly includes a flare branch pipe, an outer pipe, and a flare channel. A sealing pipe is fixedly installed inside the outer pipe. The bottom end of the sealing pipe extends to the lower side of the outer pipe and communicates with the top end of the flare branch pipe. One end of the flare channel is connected to the combustion cylinder, and the other end is connected to the outer pipe. The flare branch pipe is L-shaped, with its top end connected to the sealing pipe and its bottom end connected to the flare distribution pipe. The outer tube is provided with a limiting component for controlling the opening and closing of the sealing tube. The limiting component includes a sleeve, a sliding rod, and a float. The sleeve is fixedly installed at the top of the outer tube. The sliding rod is slidably connected to the sleeve. The float is fixedly installed at the bottom end of the sliding rod. The sliding rod drives the float to approach or move away from the end of the sealing tube.

[0006] Furthermore, the sleeve is fixedly mounted on the inner top of the outer tube by a flange cover.

[0007] Furthermore, a flange is fixed between the outer pipe and the flare branch pipe, and the connection is secured by nuts and bolts.

[0008] Furthermore, there is a gap between the sealing tube and the outer tube, and the gap is connected to the bottom opening of the combustion cylinder through a drain pipe.

[0009] Furthermore, the combustion zone of the combustion tube is fitted with a heat insulation layer.

[0010] Furthermore, the bottom end of the flare distribution pipe is fixedly connected to a flare diameter reducer and / or the top end of the flare distribution pipe is welded with a cap.

[0011] Furthermore, the angle between the flare channel and the combustion cylinder is 45 degrees.

[0012] Furthermore, a fixing plate is fixedly provided at the bottom of the outer tube. The fixing plate is arranged around the periphery of the portion of the sealing tube that extends out of the outer tube and is fixedly connected to the outer wall of the sealing tube.

[0013] Furthermore, the flare distribution pipe is connected to the combustion cylinder through multiple connecting components, and each connecting component is arranged in a circular array around the center of the combustion cylinder.

[0014] Compared with the prior art, the present invention has the following advantages: In this invention, the float moves up and down with the changes in gas pressure and flow rate inside the flare head, thereby controlling the opening and closing of the sealing tube. This allows the flare head to flexibly cope with various operating conditions, from small to large venting volumes, avoiding problems such as unstable combustion or gas leakage caused by changes in venting volume, and improving the applicability and reliability of the flare head in different production scenarios.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0020] The following will refer to the appendix. Figures 1 to 3 The present invention will be described in detail with reference to the embodiments.

[0021] Overall, the present invention discloses a flare head with strong adaptability to venting volume, including a flare distribution pipe 10, a combustion cylinder 1, and a connecting assembly, wherein the flare distribution pipe 10 and the combustion cylinder 1 are connected by the connecting assembly. The connecting components include a flare branch pipe 8, an outer pipe 15, and a flare channel 3. A sealing pipe 14 is fixedly installed inside the outer pipe 15. The bottom end of the sealing pipe 14 extends to the lower side of the outer pipe 15 and communicates with the top end of the flare branch pipe 8. One end of the flare channel 3 is connected to the combustion cylinder 1, and the other end is connected to the outer pipe 15. The flare branch pipe 8 is L-shaped, with its top end connected to the sealing pipe 14 and its bottom end connected to the flare distribution pipe 10. In addition, such as Figure 1 As shown, the outer tube 15 is provided with a limiting component for controlling the opening and closing of the sealing tube 14. The limiting component includes a sleeve 18, a sliding rod 17, and a float 16. The sleeve 18 is fixedly installed at the top of the outer tube 15. The sliding rod 17 is slidably connected inside the sleeve 18. The float 16 is fixedly installed at the bottom end of the sliding rod 17. The sliding rod 17 drives the float 16 to approach or move away from the end of the sealing tube 14.

[0022] In this embodiment, the float 16 moves up and down with the changes in gas pressure and flow rate inside the flare head, thereby controlling the opening and closing of the sealing tube 14. This allows the flare head to flexibly cope with various operating conditions from small to large venting volumes, avoiding problems such as unstable combustion or gas leakage caused by changes in venting volume, and improving the applicability and reliability of the flare head in different production scenarios.

[0023] In practical operation, when the venting volume in the flare distribution pipe 10 is small, the gas enters the sealing pipe 14 through the flare branch pipe 8. At this time, due to the low gas pressure and flow rate, the float 16 is positioned low under gravity, close to the end of the sealing pipe 14. The gas can still enter the outer pipe 15 through the sealing pipe 14, and then enter the combustion chamber 1 through the flare channel 3 for combustion. During this process, the limiting component plays a regulating role, ensuring that the gas can enter the combustion chamber 1 stably and maintain stable combustion.

[0024] It should be understood that as the amount of vented gas in the flare distribution pipe 10 increases, the pressure and flow rate of the gas after entering the sealing pipe 14 increase. The increased gas pressure pushes the float 16 upward, causing it to slide upward along the sliding rod 17, away from the end of the sealing pipe 14. The sealing pipe 14 is in an unobstructed state, allowing more gas to quickly pass through it into the outer pipe 15, and then through the flare channel 3 into the combustion chamber 1, to meet the combustion requirements under a larger venting volume. At this time, the flame of the flare head will increase accordingly, but it can still maintain stable combustion.

[0025] Furthermore, when the venting volume decreases or stops, the gas pressure and flow rate within the sealing tube 14 decrease accordingly. The float 16 gradually slides downwards under gravity, approaching the end of the sealing tube 14. If the venting volume decreases to a certain extent, the float 16 will eventually seal the end of the sealing tube 14, preventing gas from continuing to enter the outer tube 15 through the sealing tube 14, thus avoiding unstable combustion or gas accumulation within the torch head due to insufficient gas volume. When venting completely stops, the float 16 remains in the sealed tube 14 state, awaiting the start of the next venting operation.

[0026] In this preferred embodiment, the sleeve 18 is fixedly mounted on the inner top of the outer tube 15 via the flange cover 4. A flange 5 is fixedly provided between the outer tube 15 and the flare branch tube 8, and is fixedly connected by nuts 7 and bolts 6.

[0027] It should be noted that since the sleeve 18 is fixed to the top of the outer tube 15 via the flange cover 4, when maintenance or replacement of components in the limiting assembly is required, the flange cover 4 and sleeve 18 can be easily removed simply by unscrewing the bolts 6 on the flange cover 4, without the need for extensive disassembly of the entire flare head. The outer tube 15 and the flare branch pipe 8 are connected by flange 5 and nuts 7 and bolts 6. When it is necessary to inspect, clean, or replace the seals at the connection, the operator can remove the bolts 6 to separate the outer tube 15 and the flare branch pipe 8, complete the corresponding maintenance work, and then reinstall them.

[0028] As a preferred structure in this embodiment, such as Figure 1 As shown, there is a gap between the sealing tube 14 and the outer tube 15, and this gap is connected to the bottom opening of the combustion cylinder 1 through the drain pipe 12.

[0029] As a preferred embodiment, the flame combustion area of ​​the combustion tube 1 is fitted with a heat insulation layer 2. This configuration reduces the diffusion of heat generated by the torch head combustion into the surrounding environment, thereby reducing thermal pollution to the surrounding environment.

[0030] In this embodiment, a gap is provided between the sealing pipe 14 and the outer pipe 15, and a drainage system is formed by connecting the drainage pipe 12 to the bottom opening of the combustion cylinder 1. During rainy weather, rainwater enters the outer pipe 15, flows into the gap, and is then smoothly discharged to the bottom opening of the combustion cylinder 1 through the drainage pipe 12. Since the bottom of the combustion cylinder 1 is usually open to the outside atmosphere or has a dedicated drainage design, rainwater can be discharged promptly.

[0031] It needs to be further explained that, such as Figure 1 As shown, the bottom end of the flare distribution pipe 10 is fixedly connected to a flare reducer 9 and / or a cap 11 is welded to the bottom end of the flare distribution pipe 10. The flare reducer 9 can change the pipe diameter between the flare distribution pipe 10 and the pre-pipe. In addition, the cap 11 is welded to the top of the flare distribution pipe 10, which can completely seal the top of the distribution pipe and prevent the leakage of venting gas.

[0032] In this embodiment, the angle between the flare channel 3 and the combustion chamber 1 is 45 degrees. This facilitates a smoother introduction of the gas flowing from the outer pipe 15 into the flare channel 3 into the combustion chamber 1.

[0033] Based on the above configuration, a fixing plate 13 is also fixedly provided at the bottom of the outer tube 15. The fixing plate 13 is arranged around the periphery of the portion of the sealing tube 14 that extends out of the outer tube 15 and is fixedly connected to the outer wall of the sealing tube 14.

[0034] It should be noted that the fixing plate 13 is arranged around the portion of the sealing tube 14 that extends out of the outer tube 15 and is fixedly connected to the outer wall of the sealing tube 14, thus forming a fixed support for the sealing tube 14 at the bottom of the outer tube 15. This ensures the structural stability of the entire device by withstanding various external forces that the sealing tube 14 may experience during operation.

[0035] In addition, such as Figure 3 As shown, the flare distribution pipe 10 is connected to the combustion cylinder 1 through multiple connecting components, which are arranged in a circular array around the center of the combustion cylinder 1. This configuration ensures that the gas from the flame distribution pipe can be evenly delivered to the circumference of the combustion cylinder 1 through multiple paths, providing conditions for stable combustion of the gas in the combustion cylinder 1 and avoiding flame deflection and unstable combustion that may be caused by unilateral or asymmetrical gas intake.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
