Description

Technical Field

[0001] This invention belongs to the field of ground flare technology, specifically relating to a high-efficiency and energy-saving ground flare. Background Technology

[0002] Ground flare systems are special combustion facilities used to handle combustible and toxic gases and vapors that cannot be recovered and reprocessed in petrochemical plants, refineries, chemical plants and other plants or facilities. They are an important measure to ensure safe production in plants and reduce environmental pollution.

[0003] For example, the invention patent with application number CN201110226966.3 discloses a high-efficiency and energy-saving ground flare gas system, which includes a flare cylinder (7) and a windproof and noise-reducing screen (1). The flare cylinder (1) is located in the windproof and noise-reducing screen (1). The lower part of the flare cylinder (7) is provided with an air inlet, and the upper part of the cylinder is provided with a fire observation door (6). Its feature is that a primary burner (9) is installed in the center of the flare cylinder (7), and a ring of secondary burners (10) is installed around the primary burner (9). The system consists of a ring of three-stage burners (11) and a ring of four-stage burners (5). The two-stage burners (10), the three-stage burners (11), and the four-stage burners (5) are connected to each other via their respective annular distribution pipes (12). The air inlet of each annular distribution pipe (12) is connected to the flare gas source via a corresponding air inlet pipe (16). A pneumatic shut-off valve is installed on each air inlet pipe (16). Each burner is equipped with a nightlight (13) and an igniter (14). This invention achieves energy saving through graded control and optimized combustion, and has the advantages of simple structure, safety, and low investment.

[0004] When the aforementioned application is in use, during the process of air entering the flare tube through the gap between the windproof and soundproof screen and the flare tube, the air in the inner ring burner is relatively insufficient compared to the outer ring burner due to the different distances between the multi-ring burners and the windproof and soundproof screen. This results in the outer ring burner having a greater combustion effect than the inner ring burner. Moreover, due to the influence of the outer ring burner, the inner ring burner often experiences flameout, resulting in poor combustion of the vented gas in the inner ring burner.

[0028] A high-efficiency and energy-saving ground flare, such as Figure 1-9 As shown, the system includes a chimney 2 and a windshield 1 corresponding to the chimney 2. A combustion mechanism is installed inside the chimney 2, and a flow guiding mechanism cooperating with the combustion mechanism is installed at the bottom of the chimney 2. A support 4 is fixedly connected to the chimney 2, and air inlets corresponding to the chimney 2 are evenly distributed along the circumference of the support 4. The flow guiding mechanism includes an inner support cylinder 8 coaxially arranged with the chimney 2, and several circumferential wind guide plates 6 are rotatably connected to the inner support cylinder 8. The other ends of the several circumferential wind guide plates 6 are rotatably connected to the chimney 2. A drive unit is provided on the chimney 2, and a synchronization unit is connected to the drive unit to drive the several circumferential wind guide plates 6 to rotate synchronously. Multiple radial wind guide plates 7 are rotatably connected to the several circumferential wind guide plates 6, and the multiple radial wind guide plates 7 rotate synchronously with the circumferential wind guide plates 6 as they rotate along the chimney 2. The radial wind guide plates 7 can drive the air inside the chimney 2 to flow towards the inner circle of the combustion mechanism.

[0029] In use, the vented air enters the combustion mechanism through a pipe. The air enters the chimney 2 between the chimney 2 and the windshield 1, and comes into contact with the combustion mechanism under the guidance of the flow guiding mechanism, causing the vented air to burn. Specifically, the circumferential wind guide plate 6 guides the air in the circumferential direction to ensure the uniformity of air in all parts of the chimney 2 in the circumferential direction. In addition, the radial wind guide plate 7, whose axis intersects the axis of the chimney 2, guides the air inward so that more air from the outer ring can enter the inner ring and come into contact with the combustion mechanism in the inner ring, ensuring the uniformity of combustion in the combustion mechanism. Furthermore, by adjusting the deflection angle of the circumferential wind guide plate 6 and the radial wind guide plate 7, the ratio of air in the inner and outer rings of the combustion mechanism is changed, thereby improving the combustion effect of the combustion mechanism. The flow guiding structure can be adjusted according to the amount of air entering the chimney 2 to ensure the uniformity of air in the inner and outer rings of the combustion mechanism.

[0030] Furthermore, the circumferential guide vane 6 is provided with a connecting unit, which synchronously drives the radial guide vane 7 to rotate as the circumferential guide vane 6 rotates; through the setting of the synchronization unit and the connecting unit, several circumferential guide vanes 6 and radial guide vanes 7 can move synchronously, reducing the use of the drive unit in this application and reducing the manufacturing cost of this application.

[0031] Furthermore, such as Figure 3-5 As shown, the synchronization unit includes a rotating shaft that is fixedly connected to the chimney 2 and rotatably connected to the plurality of circumferential guide vanes 6, and an adjusting rod 9 is detachably connected to the rotating shaft; a synchronization rod 10 is provided between adjacent adjusting rods 9, and the two ends of the synchronization rod 10 are rotatably connected to the adjusting rod 9 through ball joints; the drive unit includes a reduction motor 3 fixedly connected to the chimney 2, and a crank 11 is connected to the output end of the reduction motor 3; a connecting rod 12 is rotatably connected to the crank 11, and a rocker arm 13 is rotatably connected to the connecting rod 12, and the rocker arm 13 is fixedly connected to one of the adjusting rods 9.

[0032] When the drive unit and synchronization unit are in use, the geared motor 3 is started, and the geared motor 3 drives the crank 11 to rotate. Since the crank 11, connecting rod 12 and rocker 13 form the crank 11 rocker 13 mechanism, when the crank 11 rotates, the crank 11 can drive the rocker 13 to swing back and forth through the connecting rod 12. The rocker 13 drives one of the adjusting rods 9 to rotate. The adjusting rod 9 drives the adjacent adjusting rod 9 to rotate through the synchronization rod 10, thereby making several adjusting rods 9 rotate synchronously, and making several peripheral air guides 6 rotate synchronously, thereby adjusting the air guiding effect of the peripheral air guides 6.

[0033] Furthermore, such as Figure 8As shown, the adjusting rod 9 has a mating hole that mates with the rotating shaft, and a splined shaft 21 that mates with the rotating shaft is also fixedly connected to the adjusting rod 9. The rotating shaft has a splined groove that mates with the splined shaft 21. By mating the adjusting rod 9 with the rotating shaft and by mating the splined shaft 21 with the splined groove on the rotating shaft, the stability of the connection between the adjusting rod 9 and the rotating shaft is improved. The splined shaft 21 has a through hole through which a mounting bolt that is screwed to the rotating shaft passes. The rotating shaft has a threaded groove that mates with the mounting bolt. By mating the mounting bolt with the threaded groove, the adjusting rod 9 and the mounting bolt can be detachably connected.

[0034] Furthermore, such as Figure 7 As shown, the connecting unit includes several fixed gears 17 coaxially arranged with several rotating shafts and fixedly connected to the chimney 2. Planetary gears 18 meshing with the fixed gears 17 are rotatably connected to the circumferential guide vanes 6. A driving bevel gear 19 is coaxially fixedly connected to the planetary gears 18. A driven bevel gear 20 meshes with the driving bevel gear 19. A driving rod 16 is connected to the driven bevel gear 20. A driving rod 15 is rotatably connected to the driving rod 16. Parallel rods 14 are coaxially fixedly connected to multiple radial guide vanes 7. The other ends of multiple parallel rods 14 are rotatably connected to the driving rod 15.

[0035] When the circumferential guide vane 6 rotates, it drives the planetary gear 18 to rotate along the fixed gear 17. Under the action of the fixed gear 17, the planetary gear 18 rotates along the circumferential guide vane 6. The planetary gear 18 drives the driving bevel gear 19 to rotate, and the driving bevel gear 19 drives the driving rod 16 to rotate. Since the driving rod 16, the parallel rod 14, and the drive rod 15 form a parallelogram mechanism, when the driving rod 16 rotates, the driving rod 16 can drive multiple parallel rods 14 to rotate synchronously through the drive rod 15. The parallel rods 14 drive the radial guide vane 7 to rotate, thereby adjusting the radial guide vane 7 to change the air ratio of the inner and outer rings of the combustion mechanism and improve the combustion effect of the combustion mechanism.

[0036] Furthermore, such as Figure 2 and Figure 9 As shown, the combustion mechanism includes multiple annular flare pipes arranged radially along the chimney 2, and several burners 5 are evenly distributed around the circumference of each of the multiple flare pipes; a connecting pipe connects adjacent flare pipes, and an air inlet pipe is connected to the outermost flare pipe; each burner 5 includes a riser 22 connected to the flare pipe, and several connecting pipes 23 are evenly distributed around the circumference of the riser 22; each of the several connecting pipes 23 is connected to a horizontally arranged nozzle 24, and vertical nozzles 25 are evenly distributed around the axial direction on the nozzle 24, and axial nozzles 26 are provided at both ends of the nozzle 24.

[0037] The venting gas enters the outermost flare pipe through the inlet pipe. Under the action of the connecting pipe, the venting gas enters each flare pipe in sequence. The venting gas in the flare pipe enters the nozzle 24 through the riser 22 and the connecting pipe 23. The venting gas in the nozzle 24 is ejected through the vertical nozzle 25 and the axial nozzle 26 and comes into contact with the air to burn.

[0038] Furthermore, a steam ring pipe 28 is provided below the nozzle 24, and a steam pipe 27 is connected to the steam ring pipe 28. A steam hole 29 is provided on the steam ring pipe 28. A steam main pipe arranged in a ring is provided below the steam ring pipe 28, and the steam pipe 27 is connected to the steam main pipe. A common pipe is connected between multiple steam main pipes, and a main pipe is connected to the outermost steam main pipe. Steam enters the steam pipe 27 through the main pipe, the steam main pipe, and the common pipe. The steam in the steam pipe 27 is ejected through the steam hole 29 on the steam ring pipe 28 to perform smoke elimination treatment on the combustion of the exhaust gas.

[0039] like Figures 1 to 9 As shown below, the working process of the present invention will be explained in detail.

[0040] In use, air enters the chimney 2 through the space between the chimney 2 and the windshield 1. The air is guided in the circumferential direction by the circumferential guide plate 6 to ensure the uniformity of air in all parts of the chimney 2 in the circumferential direction. In addition, the air is guided inward by the radial guide plate 7 whose axis intersects with the axis of the chimney 2, so that more air from the outer ring can enter the inner ring and contact the burner 5 in the inner ring, ensuring the uniformity of combustion of the combustion mechanism.

[0041] The venting gas enters the outermost flare pipe through the inlet pipe. Under the action of the connecting pipe, the venting gas enters each flare pipe in sequence. The venting gas in the flare pipe enters the nozzle 24 through the riser 22 and the connecting pipe 23. The venting gas in the nozzle 24 is ejected through the vertical nozzle 25 and the axial nozzle 26, and burns upon contact with the air. At the same time, steam enters the steam pipe 27 through the main pipe, the steam main pipe, and the common pipe. The steam in the steam pipe 27 is ejected through the steam hole 29 on the steam ring pipe 28 to extinguish the smoke from the combustion of the venting gas.

[0042] The airflow guiding structure is adjusted according to the amount of air entering the chimney 2. Specifically, the geared motor 3 is started, which drives the crank 11 to rotate. Since the crank 11, connecting rod 12, and rocker arm 13 form a crank 11 rocker arm 13 mechanism, when the crank 11 rotates, the crank 11 can drive the rocker arm 13 to swing back and forth through the connecting rod 12. The rocker arm 13 drives one of the adjusting rods 9 to rotate. The adjusting rod 9 drives the adjacent adjusting rod 9 to rotate through the synchronizing rod 10, thereby causing several adjusting rods 9 to rotate synchronously, causing several circumferential air guide plates 6 to rotate synchronously, thereby adjusting the airflow guiding effect of the circumferential air guide plates 6.

[0043] Meanwhile, the circumferential guide vane 6 drives the planetary gear 18 to rotate along the fixed gear 17. Under the action of the fixed gear 17, the planetary gear 18 rotates along the circumferential guide vane 6. The planetary gear 18 drives the active bevel gear 19 to rotate, and the active bevel gear 19 drives the active rod 16 to rotate. Since the active rod 16, the parallel rod 14, and the drive rod 15 form a parallelogram mechanism, when the active rod 16 rotates, the active rod 16 can drive multiple parallel rods 14 to rotate synchronously through the drive rod 15. The parallel rods 14 drive the radial guide vane 7 to rotate, thereby adjusting the radial guide vane 7 to change the air ratio of the inner and outer rings of the combustion mechanism and improve the combustion effect of the combustion mechanism.
