Description

Technical Field

[0001] This application relates to the field of burner technology, and more particularly to a tree-branch type ground flare burner. Background Technology

[0002] A flare is a special combustion device used to treat combustible and toxic gases and vapors that cannot be recovered and reprocessed in petrochemical plants, refineries, chemical plants and other factories or facilities. A suitable burner is required inside the flare to fully combust the waste gas inside.

[0003] Traditional ground flare burners typically use cylindrical burners. Because the combustion of exhaust gas is too concentrated in this way, it is easy for the exhaust gas to not come into sufficient contact and mix with air during the combustion process. As a result, some exhaust gas is not completely burned, causing energy waste. At the same time, it may also emit exhaust gas containing harmful substances, polluting the environment.

[0004] Therefore, in response to the problem that the combustion of exhaust gas is too concentrated in the traditional ground flare burner and some exhaust gas is not completely burned, a tree-branch type ground flare burner can be designed. By designing the burner into a tree-branch design, the combustion area of ​​exhaust gas is increased, thereby making it easier to solve the above problems. Utility Model Content

[0005] To overcome the problems of traditional ground flare burners, which typically use cylindrical burners, the exhaust gas does not have sufficient contact and mixing with air during combustion, resulting in some exhaust gas not being completely burned, causing energy waste. Furthermore, these burners emit exhaust gas containing harmful substances, polluting the environment.

[0006] The technical solution is as follows: A tree-branch type ground flare burner includes a first igniter, a first tree-branch combustion stem, a second igniter, and a second tree-branch combustion stem; the upper end of the first igniter is surrounded by multiple sets of first tree-branch combustion stems for fully combusting exhaust gases, and a central support rod is provided at the center of the multiple sets of first tree-branch combustion stems; the upper end of the first igniter is provided with a first support joint for fixing the central support rod; the upper end of the central support rod is provided with a second igniter; the lower end of the second igniter is provided with a second support joint for fixing the upper end of the central support rod; the upper end of the second igniter is surrounded by multiple sets of second tree-branch combustion stems for further combusting exhaust gases; and the lower end of the first igniter is provided with a support mechanism for supporting the first igniter and the second igniter.

[0007] Furthermore, each of the multiple sets of first branch combustion trunks has multiple sets of first branch combustion branches linearly arranged at its outer end, and each of the multiple sets of first branch combustion branches has a first jet nozzle fixedly installed at the end away from the first branch combustion trunk.

[0008] Furthermore, the outer end of the first igniter is provided with a main gas supply pipe, and the end of the main gas supply pipe away from the first igniter is provided with a gas supply pipe for connecting to an external gas supply device.

[0009] Furthermore, each of the multiple sets of second tree branch combustion trunks has multiple sets of second tree branch combustion branches linearly arranged at its outer end, and each of the multiple sets of second tree branch combustion branches has a second air nozzle fixedly installed at both ends away from the first tree branch combustion trunk.

[0010] Furthermore, an auxiliary gas supply pipe is provided above the gas supply pipe, the lower end of which is connected to the gas supply pipe, an auxiliary gas supply valve is provided in the middle section of the gas supply pipe, and a gas receiving pipe is provided at the upper end of the auxiliary gas supply pipe. One end of the gas receiving pipe is connected to the auxiliary gas supply pipe, and the other end of the auxiliary gas supply pipe is connected to the second igniter.

[0011] Furthermore, the support mechanism includes a support base located at the bottom of the first igniter. Multiple sets of support legs are arranged around the lower end of the support base. A grounding plate is provided at the lower end of the support legs. An auxiliary support rod is provided at the upper center of the grounding plate, and the lower end of the auxiliary support rod is connected to the grounding plate.

[0012] Furthermore, multiple sets of extension rods are arranged around the lower outer side of the second igniter. The upper end of the auxiliary support rod is connected to the end of the extension rod away from the second igniter. A grounding hole is opened through the surface of the end of the grounding plate away from the support leg. The middle section of one set of auxiliary support rods is provided with a fixed sleeve for accommodating the main gas pipeline.

[0013] The beneficial effects are that, compared with traditional ground flare burners, this application greatly increases the combustion area of ​​the exhaust gas by using the first branch and second branch combustion stems and branches, and the second branch combustion stems and branches. The dispersed exhaust gas can fully contact and mix with the air, promoting a more complete combustion reaction, allowing the combustible components in the exhaust gas to burn more completely, reducing energy waste and significantly improving energy utilization. When the residue in the exhaust gas is slight, the secondary ignition works in conjunction with the primary ignition to further expand the combustion area. As the residue increases, the auxiliary gas supply valve can be flexibly adjusted to reduce or stop the secondary ignition gas supply, allowing the two ignition stages to work together to burn the exhaust gas multiple times, effectively avoiding the emission of unburned exhaust gas and adapting to the exhaust gas treatment needs under various complex working conditions.

[0020] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-3 As shown, the tree-branch type ground flare burner includes a first igniter 1, a first tree-branch combustion stem 3, a second igniter 6, and a second tree-branch combustion stem 7. The upper end of the first igniter 1 is surrounded by multiple sets of first tree-branch combustion stems 3 for fully combusting exhaust gases. A central support rod 10 is provided at the center of the multiple sets of first tree-branch combustion stems 3. The upper end of the central support rod 10 is provided with the second igniter 6. The upper end of the second igniter 6 is surrounded by multiple sets of second tree-branch combustion stems 7 for further combusting exhaust gases. The lower end of the first igniter 1 is provided with a support mechanism 2 for supporting the first igniter 1 and the second igniter 6.

[0023] Multiple sets of first tree branch combustion stems 3 are linearly provided at the outer ends of multiple sets of first tree branch combustion branches 8. A first jet nozzle 9 is fixedly installed at the end of each set of first tree branch combustion branches 8 away from the first tree branch combustion stem 3. By combining multiple sets of first tree branch combustion stems 3 and multiple sets of first tree branch combustion branches 8, the exhaust gas can be fully contacted and mixed with the combustion-supporting gas during the combustion process, while effectively increasing the combustion area of ​​the exhaust gas.

[0024] The outer end of the first igniter 1 is provided with a main gas supply pipe 5, and the end of the main gas supply pipe 5 away from the first igniter 1 is provided with a gas supply pipe 4 for connecting to an external gas supply device.

[0025] The support mechanism 2 includes a support base 201, which is located at the bottom of the first igniter 1. Multiple sets of support legs 202 are arranged around the lower end of the support base 201. A grounding plate 203 is provided at the lower end of the support legs 202. An auxiliary support rod 205 is provided at the upper center of the grounding plate 203. The lower end of the auxiliary support rod 205 is connected to the grounding plate 203. The support base 201, support legs 202 and grounding plate 203 are combined to provide stable support for the first igniter 1, the first branch burning trunk 3 and the first branch burning branch 8.

[0026] During operation, the exhaust gas enters the first igniter 1 through the gas supply pipe 4 and the main gas supply pipe 5. The first branch combustion trunk 3 and the multiple sets of first branch combustion branches 8 at its outer end disperse the exhaust gas, which is then ejected from each first jet nozzle 9. The branch-like design greatly increases the combustion area of ​​the exhaust gas, allowing it to come into more extensive contact with and mix with the air. The first igniter 1 ignites the exhaust gas, enabling it to burn fully inside the ground torch.

[0027] The working principle is that this dispersed airflow allows air to fully penetrate into the exhaust gas, promoting a more complete combustion reaction. Compared with traditional cylindrical burners, the exhaust gas is no longer burned in a concentrated manner, but is burned at multiple points simultaneously, making the combustion more uniform and complete.

[0028] Its beneficial effects are significant. On the one hand, it improves energy utilization efficiency and reduces energy waste because the combustible components in the exhaust gas are burned more completely. On the other hand, it reduces the emission of harmful substances, significantly mitigating environmental pollution and meeting environmental protection requirements, while also ensuring air quality around the factory.

[0029] Example 2

[0030] Based on Example 1, such as Figures 1-5 As shown, it also includes a first igniter 1, a first branch combustion bar 3, a second igniter 6, and a second branch combustion bar 7; the upper end of the first igniter 1 is surrounded by multiple sets of first branch combustion bars 3 for fully combusting exhaust gases, and a central support rod 10 is provided at the center of the multiple sets of first branch combustion bars 3; the upper end of the first igniter 1 is provided with a first support joint 101 for fixing the central support rod 10; the upper end of the central support rod 10 is provided with a second igniter 6; the lower end of the second igniter 6 is provided with a second support joint 14 for fixing the upper end of the central support rod 10; the upper end of the second igniter 6 is surrounded by multiple sets of second branch combustion bars 7 for further combusting exhaust gases; the lower end of the first igniter 1 is provided with a support mechanism 2 for supporting the first igniter 1 and the second igniter 6.

[0031] Multiple sets of second tree branch combustion stems 7 are linearly provided at the outer ends of each set of second tree branch combustion branches 11. Second jet nozzles 12 are fixedly installed at the two ends of each set of second tree branch combustion branches 11 away from the first tree branch combustion stem 3. By combining multiple sets of second tree branch combustion stems 7 and multiple sets of second tree branch combustion branches 11, the unburned exhaust gas is subjected to secondary combustion, so that the residual components in the exhaust gas are completely burned, ensuring that the final emissions are mainly carbon dioxide and water vapor.

[0032] An auxiliary gas supply pipe 16 is provided above the gas supply pipe 4. The lower end of the auxiliary gas supply pipe 16 is connected to the gas supply pipe 4. An auxiliary gas supply valve 17 is provided in the middle section of the gas supply pipe 4. An air inlet pipe 15 is provided at the upper end of the auxiliary gas supply pipe 16. One end of the air inlet pipe 15 is connected to the auxiliary gas supply pipe 16, and the other end of the auxiliary gas supply pipe 16 is connected to the second igniter 6.

[0033] Multiple sets of extension rods 13 are arranged around the lower outer side of the second igniter 6. The upper end of the auxiliary support rod 205 is connected to the end of the extension rod 13 away from the second igniter 6. The grounding plate 203 has a grounding hole 204 through the surface of the end away from the support leg 202. The middle section of one set of auxiliary support rods 205 is provided with a fixed sleeve 206 for accommodating the main gas pipe 5. The second igniter 6, the second branch burning trunk 7 and the second branch burning branch 11 are supported by the extension rods 13, the auxiliary support rods 205 and the middle support rod 10.

[0034] After the exhaust gas passes through the first layer of combustion, a small amount of incompletely burned exhaust gas continues to rise to the second igniter 6. At the same time, the staff can adjust the auxiliary gas supply valve 17 to allow a small amount of exhaust gas to enter the ground flare through the auxiliary gas supply pipe 16 and the gas receiving pipe 15. The small amount of incompletely burned exhaust gas continues to mix and burn with the small amount of newly entered exhaust gas.

[0035] The working principle of the secondary ignition is that gas is supplied to the second igniter 6 through the auxiliary gas supply pipe 16 and the gas receiving pipe 15, and the gas supply volume is adjusted by the auxiliary gas supply valve 17. The second igniter 6 ignites the remaining exhaust gas again, and it is further burned through the second branch combustion trunk 7 and the second branch combustion branch 11.

[0036] The beneficial effects of this design are obvious. When the residue in the exhaust gas is relatively light, the secondary ignition can work with the primary ignition to increase the combustion area of ​​the exhaust gas. As the residue in the exhaust gas increases, the staff can reduce or stop the gas supply of the secondary ignition, so that the secondary ignition works with the primary ignition to burn the exhaust gas multiple times, which improves the completeness of the combustion of the exhaust gas and effectively avoids the emission of unburned exhaust gas.
