[0003] For example, the invention patent with the application number: CN201110226966.3 discloses an energy-efficient ground flare gas system, which includes a flare cylinder body (7) and a windproof and sound-absorbing screen (1). The flare cylinder body (1) is located in the windproof and sound-absorbing screen (1). An air inlet is provided at the lower part of the flare cylinder body (7), and a viewing door (6) is provided on the cylinder body above the air inlet. Its feature is that a primary burner (9) is installed at the center of the flare cylinder body (7), and a circle of secondary burners (10), a circle of tertiary burners (11), and a circle of quaternary burners (5) are installed around the primary burner (9).

Specific embodiments

[0018] An efficient and energy-saving ground flare, as Figures 1-9 shown, includes a chimney 2 and a wind baffle 1 corresponding to the chimney 2. A combustion mechanism is provided in the chimney 2, and a flow guiding mechanism cooperating with the combustion mechanism is provided 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 on the support 4; the flow guiding mechanism includes an inner support cylinder 8 coaxially arranged with the chimney 2, and a plurality of circumferentially evenly distributed circumferential air guide plates 6 are rotatably connected to the inner support cylinder 8. The other ends of the plurality of circumferential air guide plates 6 are rotatably connected to the chimney 2, and a synchronizing device for driving the plurality of circumferential air guide plates 6 to rotate synchronously is provided on the chimney 2; a plurality of radial air guide plates 7 are rotatably connected to each of the plurality of circumferential air guide plates 6, and the plurality of radial air guide plates 7 rotate synchronously as the circumferential air guide plates 6 rotate along the chimney 2, and the radial air guide plates 7 can drive the air in the chimney 2 to flow towards the inner circle of the combustion mechanism.

[0019] When the present invention is in use, the vent gas enters the combustion mechanism through a pipeline, and the air enters the chimney 2 through the space between the chimney 2 and the wind baffle 1, and contacts the combustion mechanism under the guiding action of the flow guiding mechanism, so that the vent gas burns; specifically, the circumferential air guide plates 6 are used to guide the air in the circumferential direction to ensure the uniformity of the air at each part in the circumferential direction in the chimney 2; in addition, the radial air guide plates 7 with axes intersecting the axis of the chimney 2 guide the air inwards, so that more air in the outer circle can enter the inner circle and contact the combustion mechanism in the inner circle to ensure the uniformity of the combustion of the combustion mechanism; in addition, by adjusting the deflection angles of the circumferential air guide plates 6 and the radial air guide plates 7, the ratio of the air in the inner and outer circles of the combustion mechanism can be changed to improve 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 the air in the inner and outer circles of the combustion mechanism.

[0020] Furthermore, a driving unit is provided on the chimney 2, and a synchronization unit is connected to the driving unit, which can drive a plurality of radial air guide plates 7 to rotate synchronously; a connecting unit is provided on the circumferential air guide plate 6, and the connecting unit rotates synchronously with the circumferential air guide plate 6 to drive the radial air guide plate 7 to rotate; through the arrangement of the synchronization unit and the connecting unit, a plurality of circumferential air guide plates 6 and radial air guide plates 7 act synchronously, reducing the use of the driving unit in this application and reducing the manufacturing cost of this application.

[0021] Furthermore, as Figures 3-5 shown, the synchronization unit includes a rotating shaft fixedly connected to a plurality of the circumferential air guide plates 6 and rotatably connected to the chimney 2. An adjusting rod 9 is detachably connected to the rotating shaft; a synchronization rod 10 is provided between adjacent adjusting rods 9, and both ends of the synchronization rod 10 are rotatably connected to the adjusting rod 9 through spherical joints; the driving unit includes a reduction motor 3 fixedly connected to the chimney 2, and an output end of the reduction motor 3 is connected to a crank 11; a connecting rod 12 is rotatably connected to the crank 11, a rocker 13 is rotatably connected to the connecting rod 12, and the rocker 13 is fixedly connected to one of the adjusting rods 9.

[0022] When the driving unit and the synchronization unit are in use, the reduction motor 3 is started, and the reduction motor 3 drives the crank 11 to rotate. Since the crank 11, the connecting rod 12, and the rocker 13 form a crank-rocker mechanism, when the crank 11 rotates, the crank 11 can drive the rocker 13 to reciprocate through the connecting rod 12. The rocker 13 drives one of the adjusting rods 9 to rotate, and the adjusting rod 9 drives the adjacent adjusting rods 9 to rotate through the synchronization rod 10, so that a plurality of adjusting rods 9 rotate synchronously, and a plurality of circumferential air guide plates 6 rotate synchronously, thereby adjusting the air guiding effect of the circumferential air guide plates 6.

[0023] Furthermore, as Figure 8 shown, the adjusting rod 9 is provided with a fitting hole for cooperating with the rotating shaft, and a spline shaft 21 for cooperating with the rotating shaft is also fixedly connected to the adjusting rod 9. The rotating shaft is provided with a spline groove for cooperating with the spline shaft 21; through the cooperation of the fitting hole and the rotating shaft and the cooperation of the spline shaft 21 and the spline groove on the rotating shaft, the connection stability between the adjusting rod 9 and the rotating shaft is improved; a through hole is provided on the spline shaft 21, and a mounting bolt screwed to the rotating shaft is inserted through the through hole. The rotating shaft is provided with a threaded groove for cooperating with the mounting bolt; through the cooperation of the mounting bolt and the threaded groove, the detachable connection between the adjusting rod 9 and the mounting bolt is realized.

[0024] Furthermore, as Figure 7As shown in the figure, the connecting unit includes a plurality of fixed gears 17 that are fixedly connected to the chimney 2 and are coaxially arranged with a plurality of the rotating shafts. A planet gear 18 that meshes with the fixed gear 17 is rotatably connected to the circumferential air guide plate 6; the planet gear 18 is coaxially and fixedly connected with a driving bevel gear 19, a driven bevel gear 20 meshes with the driving bevel gear 19, a driving rod 16 is connected to the driven bevel gear 20, and a driving rod 15 is rotatably connected to the driving rod 16; a parallel rod 14 is coaxially and fixedly connected to each of the plurality of radial air guide plates 7, and the other ends of the plurality of parallel rods 14 are rotatably connected to the driving rod 15.

[0025] When the circumferential air guide plate 6 rotates, the circumferential air guide plate 6 drives the planet gear 18 to rotate along the fixed gear 17. Under the action of the fixed gear 17, the planet gear 18 rotates along the circumferential air guide plate 6; the planet gear 18 drives the driving bevel gear 19 to rotate, and the driving bevel gear 19 drives the driving rod 16 to rotate; since a parallelogram mechanism is formed among the driving rod 16, the parallel rod 14, and the driving rod 15, when the driving rod 16 rotates, the driving rod 16 can drive a plurality of parallel rods 14 to rotate synchronously through the driving rod 15, and the parallel rod 14 drives the radial air guide plate 7 to rotate, thereby adjusting the radial air guide plate 7 to change the proportion of air in the inner ring and outer ring combustion mechanisms and improving the combustion effect of the combustion mechanism.

[0026] Further, as Figure 2 and Figure 9 shown in the figure, the combustion mechanism includes a plurality of annular torch gas pipes arranged radially along the chimney 2. A plurality of burners 5 are evenly distributed along the circumference on each of the plurality of torch gas pipes; a communicating pipe is connected between adjacent torch gas pipes, and an intake pipe is connected to the outermost torch gas pipe; the burner 5 includes a riser pipe 22 connected to the torch gas pipe. A plurality of connecting pipes 23 are evenly distributed along the circumference on the riser pipe 22; a horizontal nozzle 24 is connected to each of the plurality of connecting rods 12. A plurality of vertical spray holes 25 are evenly distributed along the axial direction on the nozzle 24, and axial spray holes 26 are provided at both ends of the nozzle 24.

[0027] The vent gas enters the outermost torch gas pipe through the intake pipe. Under the action of the communicating pipe, the vent gas sequentially enters each torch gas pipe; the vent gas in the torch gas pipe enters the nozzle 24 through the riser pipe 22 and the connecting pipe 23, and the vent gas in the nozzle 24 is sprayed out through the vertical spray holes 25 and the axial spray holes 26 and burns in contact with the air.

[0028] Further, a steam manifold 28 is provided below the nozzle 24. A steam pipe 27 is connected to the steam manifold 28, and steam holes 29 are provided on the steam manifold 28. A steam main pipe arranged in a ring shape is provided below the steam manifold 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 pipes, and the common pipe. The steam in the steam pipe 27 is ejected through the steam holes 29 on the steam manifold 28 to perform smoke elimination treatment on the combustion of the vent gas.

[0029] As Figures 1 to 9 shown, the working process of the present invention will be specifically explained below.

[0030] When the present invention is in use, air enters the chimney 2 between the chimney 2 and the windshield 1. The circumferential air guide plate 6 is used to guide the air in the circumferential direction to ensure the uniformity of the air at each part in the circumferential direction of the chimney 2. In addition, the radial air guide plate 7 whose axis intersects with the axis of the chimney 2 guides the air inward, so that more air in the outer circle can enter the inner circle and contact the burner 5 in the inner circle to ensure the uniformity of the combustion of the combustion mechanism.

[0031] The vent gas enters the outermost flare gas pipe through the intake pipe. Under the action of the connecting pipe, the vent gas enters each flare gas pipe in turn. The vent gas in the flare gas pipe enters the nozzle 24 through the riser pipe 22 and the connecting pipe 23. The vent gas in the nozzle 24 is ejected through the vertical spray holes 25 and the axial spray holes 26 to contact and burn with the air. At the same time, steam enters the steam pipe 27 through the main pipe, the steam main pipes, and the common pipe. The steam in the steam pipe 27 is ejected through the steam holes 29 on the steam manifold 28 to perform smoke elimination treatment on the combustion of the vent gas.

[0032] According to the amount of air entering the chimney 2, the diversion structure is adjusted. Specifically, the reduction motor 3 is started, and the reduction motor 3 drives the crank 11 to rotate. Since the crank 11, the connecting rod 12, and the rocker 13 form a crank-rocker mechanism, when the crank 11 rotates, the crank 11 can drive the rocker 13 to swing reciprocally through the connecting rod 12. The rocker 13 drives one of the adjusting rods 9 to rotate, and the adjusting rod 9 drives the adjacent adjusting rod 9 to rotate through the synchronizing rod 10, so that several adjusting rods 9 rotate synchronously, and several circumferential air guide plates 6 rotate synchronously, thereby adjusting the diversion effect of the circumferential air guide plates 6.

[0033] Meanwhile, the circumferential guide vane 6 drives the planet gear 18 to rotate along the fixed gear 17. Under the action of the fixed gear 17, the planet gear 18 rotates along the circumferential guide vane 6. The planet gear 18 drives the driving bevel gear 19 to rotate, and the driving bevel gear 19 drives the driving rod 16 to rotate. Since a parallelogram mechanism is formed among the driving rod 16, the parallel rod 14, and the driving rod 15, when the driving rod 16 rotates, the driving rod 16 can drive a plurality of parallel rods 14 to rotate synchronously through the driving rod 15, and 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 combustion mechanisms and improving the combustion effect of the combustion mechanism.
