Description

Technical Field

[0001] The present invention belongs to the technical field of gas blow-off combustion, and specifically relates to a pilot flame windproof burner and a coke oven gas burner. Background Art

[0002] The pilot flame windproof burner and the coke oven gas burner are key equipment for burning coke oven gas in the coking industry. The pilot flame windproof burner is designed to stably burn under various climatic conditions and is usually equipped with a windproof structure and a high-energy igniter to ensure the reliability of ignition and the stability of combustion. The coke oven gas burner is an automated combustion device that integrates combustion and control, and is mainly applied to roasters, rotary kilns, fluidized bed furnaces, boilers, hot blast stoves, etc., and can achieve automatic temperature control and remote monitoring.

[0003] A patent application with the publication number CN1344885A discloses a coke oven gas burner, which includes a combustion cylinder, a combustion nozzle, and a coke oven gas blow-off tower. This coke oven gas burner facilitates the ignition and combustion of gas. Utilizing the characteristics that the specific gravities of blast furnace gas and nitrogen and other flame-retardant gases are different from that of coke oven gas and the flame-retardant gases are not easily combustible, a flame-retardant gas seal that prevents flame flashback is formed in the U-shaped flame arrester, which can effectively prevent gas backfire. It is a burner with a simple structure, scientific design, and safety and reliability.

[0004] Currently, the commonly used coke oven gas roaster is mainly used for roasting ladles, tundishes, etc. To avoid air leakage, a thin steel pipe is often used as the burner to lead out the pilot flame. Due to the influence of factors such as the pressure fluctuation of the self-produced coke oven gas pipeline and the external environmental factors, the pilot flame often goes out. If the on-site workers do not discover and handle it in time, it will lead to gas leakage, thus posing a greater safety hazard.

[0005] Therefore, the present invention provides a pilot flame windproof burner and a coke oven gas burner. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem that due to the influence of factors such as the pressure fluctuation of the self-produced coke oven gas pipeline and the external environmental factors, the pilot flame often goes out. If the on-site workers do not discover and handle it in time, it will lead to gas leakage, thus posing a greater safety hazard.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A pilot flame windproof burner described in the present invention includes a coke oven gas burner and a pilot flame windproof burner. The pilot flame windproof burner is arranged at one end of the coke oven gas burner. A windproof cover is arranged at one end of the pilot flame windproof burner. A plurality of holes are opened on the inner wall of the top end of the windproof cover. The opening of the plurality of holes can ensure the oxygen required for the combustion of the pilot flame and form a wind tunnel effect to weaken the wind pressure. A wire mesh is fixedly installed at the top end of the windproof cover, and the wire mesh is arranged directly above the pilot flame windproof burner;

[0008] By connecting the coke oven gas burner with the pilot flame windproof burner, and connecting the windproof cover to one end of the pilot flame windproof burner, then controlling the coke oven gas burner to conduct coal feeding, ignition and combustion operations on the pilot flame windproof burner. The setting of the windproof cover can effectively avoid the influence of external factors such as wind, which is more conducive to the combustion of the flame inside the windproof cover. Through the continuous combustion of the flame, the wire mesh on the top of the windproof cover will be affected by the temperature of the flame and turn red and heat up. When the gas pressure fluctuates and causes the flame to go out, since the ignition temperature of the coke oven gas is about 600 degrees and the temperature of the red-hot wire is above 700 degrees, the temperature of the wire can ignite the coke oven gas, ensuring the stability of the pilot flame and preventing the on-site workers from failing to detect and handle in time, which may lead to gas leakage and pose a great safety hazard.

[0009] Preferably, the pilot flame windproof burner includes a cylinder. The inner wall of the cylinder is fixedly installed with a gas pipe. The outer wall of the gas pipe is fixedly installed with a controller. The top of the gas pipe is fixedly installed with a nozzle. A plurality of shunt pipes are fixedly installed between the bottom of the nozzle and the top of the gas pipe. An igniter is arranged outside the nozzle. The controller and the igniter are connected by a high-temperature conduit. When the coke oven gas is introduced into the gas pipe, the coke oven gas in the gas pipe is divided into multiple strands and flows into the nozzle in a downstream manner. Then, the controller controls the igniter to ignite the nozzle, and the coke oven gas in the nozzle will be affected by the igniter and burn, thus achieving the effect of starting a fire.

[0010] Preferably, an air guiding platform is fixedly installed on the inner wall of the cylinder. The outer walls of the igniter and the controller are both fixedly connected to the inner wall of the top end of the air guiding platform. A plurality of air inlet holes are formed in the inner wall of the air guiding platform, and the positions where the plurality of air inlet holes are formed are at one end of the air guiding platform. An inclined ladder block is fixedly installed on the inner wall of the wind shield, and the installation position of the inclined ladder block is at the other end of the air guiding platform. The outer shape of the inclined ladder block is set as an inclined convex shape, and an air inlet ring opening is formed between the protruding end of the inclined ladder block and the top end of the air guiding platform. When the coke oven gas burns in the nozzle at one end of the cylinder, due to the placement of the cylinder in the air, during the combustion process of the flame, the heat and gas expansion generated by the combustion will cause the surrounding air to expand due to heat, forming a density difference. This density difference causes an upward air flow to be generated in the flame and its surrounding air. The gas in the flame expands due to heat, its volume becomes larger, and its density becomes smaller. At the same time, the heat generated by the flame causes the surrounding air to also expand due to heat. Due to the existence of the density difference, the colder and denser air below the flame will be pushed upward, forming an upward air flow. The convective motion caused by the heat and gas expansion generated during the combustion process. This convective motion keeps the flame in an upward shape and also causes a phenomenon of air flow surging at the lower part of the flame. Therefore, when the cylinder is placed in the air, air flows into the cylinder from the air inlet holes, and the air flowing into the cylinder smoothly flows upward through the opening between the air guiding platform and the inclined ladder block. Since the opening between the air guiding platform and the inclined ladder block is an annular opening and the upper part of the inclined ladder block is an arc-shaped inclined surface, when the air flow moves upward, it can stably enhance the turbulent nature of the flame, making the flame front thicker and forming a region, achieving the effect of assisting combustion.

[0011] Preferably, a ring plate is fixedly installed at the top end of the cylinder, and a plurality of connecting rods are fixedly installed at the bottom of the wind shield. A plurality of sliding rod openings are formed at the top of the ring plate, and a plurality of rectangular grooves are fixedly installed on the inner wall of the ring plate. A clamping rod is slidably connected to the inner wall of each of the plurality of rectangular grooves. A shaft rod is fixedly installed on the inner wall of each of the plurality of rectangular grooves. A return spring is provided between one side of each of the plurality of clamping rods and the inner wall of each of the plurality of rectangular grooves. One end of each of the plurality of clamping rods can be clamped with the inner wall of each of the plurality of connecting rods respectively. The outer wall of the wind shield is symmetrically and fixedly provided with a force application handle. When connecting the wind shield and the cylinder, by inserting the connecting rods at the bottom of the wind shield into the ring plate through the sliding rod openings, and then rotating the wind shield, when the wind shield rotates, it drives the connecting rods to rotate in the sliding rod openings, and the connecting rods will squeeze the clamping rods to move backward in the rectangular grooves. When rotating the wind shield to drive the connecting rods to move to a certain position, the clamping rods will be clamped into the connecting rods under the elastic thrust of the return spring for connection and installation. When the combustion operation ends, by first cooling the wind shield, and then rotating the wind shield, the connecting rods at the bottom end of the wind shield are rotated out of the clamping rods, and then the wind shield is lifted, the wind shield and the cylinder can be separated, which is convenient for cleaning the nozzle after combustion and preventing the slag and dirt generated during combustion from blocking the nozzle, which is not conducive to subsequent combustion. The setting of the force application handle provides a good force application point for rotating the wind shield, which is more conducive to disassembly.

[0012] Preferably, an ash-removing box is fixedly installed at the top of the wind shield. Ash scraping plates are symmetrically arranged inside the ash-removing box. The two ash scraping plates are slidably connected to the inner wall of the wind shield. One end of each of the two ash scraping plates can scrape at the bottom of the wire mesh. Rectangular boxes are symmetrically and fixedly installed on the inner wall of the ash-removing box. One end of the bottom of each of the two ash scraping plates is fixedly installed with a displacement block. The outer walls of the two displacement blocks are respectively slidably connected to the inner walls of the two rectangular boxes. When a combustion operation is completed, by pushing the two ash scraping plates, one on the left and one on the right, inward, the two ash scraping plates drive the displacement blocks to slide on the rectangular boxes. When the displacement blocks slide to one end of the rectangular boxes, at this time, the two ash scraping plates are attached to the bottom of the wire mesh. Then, pull the two ash scraping plates to open to both sides, and one end of each of the two ash scraping plates will scrape at the bottom of the wire mesh, scraping off the black solids generated at the bottom of the wire mesh during combustion, preventing excessive black solids at the bottom of the wire mesh during combustion from affecting the heat absorption effect of the wire mesh, resulting in the ignition temperature of the wire mesh being unable to re-ignite the long flame when the long flame extinguishes during the next combustion operation.

[0013] Preferably, a cross plate is rotatably connected to the inner wall of the rectangular box. A plurality of pressure-bearing springs are arranged between the bottom of the cross plate and the bottom of the inner wall of the rectangular box. The bottom of the displacement block is slidably connected to the top of the cross plate. Ash disposal boxes are symmetrically arranged on both sides of the rectangular box. When the two ash scraping plates are attached to the bottom of the wire mesh, by pressing down the ash scraping plates, the ash scraping plates will squeeze the cross plate in the rectangular box through the displacement blocks. When the cross plate rotates in the rectangular box and squeezes the pressure-bearing springs, the displacement blocks will move downward, and one end of the ash scraping plates will tilt up, so that one end of the ash scraping plates changes from the state of being placed at the bottom of the wire mesh to the state of being attached to the bottom of the wire mesh. Then, pull the ash scraping plates, and the two ash scraping plates will scrape the black solids at the bottom of the wire mesh onto the ash scraping plates. Through the inclined surface setting of the ash scraping plates, the scraped black solids will slide into the two ash disposal boxes along the inclined surfaces of the ash scraping plates, preventing the black solids from falling into the device during the scraping process and affecting the operation of the device.

[0014] Preferably, fire baffle rods are symmetrically and slidably connected to the inner wall of the ash removal box. The two fire baffle rods can be respectively slidably connected to the tops of the two ash scraping plates and the inner wall of the wind guard. Slide sleeves are symmetrically and fixedly installed on the inner wall of the ash removal box. The inner walls of the two slide sleeves are symmetrically and slidably connected with clamping shafts. Two clamping grooves are symmetrically formed on the inner walls of the two fire baffle rods. One ends of the multiple clamping shafts can be respectively clamped with the inner walls of the multiple clamping grooves. A push shaft spring is arranged between the inner wall of the slide sleeve and one end of the clamping shaft. When a combustion operation is completed, by pulling the fire baffle rods, the two fire baffle rods slide out from between the tops of the ash scraping plates and the inner wall of the wind guard. During the sliding, the inner sides of the fire baffle rods squeeze the clamping shafts to slide. When the fire baffle rods completely move away from the tops of the ash scraping plates, the clamping grooves at one ends of the fire baffle rods will move to the positions of the clamping shafts. Through the elastic thrust of the push shaft spring, one ends of the clamping shafts will be clamped into the clamping grooves, so as to open the opening between the tops of the ash scraping plates and the inner wall of the wind guard, facilitating the subsequent ash removal operation of the ash scraping plates. After the ash removal operation of the ash scraping plates is completed, by pushing the fire baffle rods to reset, the clamping shafts will be re-clamped into the clamping grooves at the other ends of the fire baffle rods for limiting, so that the fire baffle rods backfill the gap between the tops of the ash scraping plates and the inner wall of the wind guard, preventing the long flame from burning into the inside of the ash removal box during the combustion operation and damaging the internal structure of the ash removal box.

[0015] Preferably, a coke oven gas burner uses the long flame-proof burner described above and includes a cavity. The cavity is fixedly installed at one end of a cylinder. A mixing gas pipe is fixedly installed on one side of the cavity. The mixing gas pipe is placed inside the cylinder. One end of the mixing gas pipe is fixedly connected to a gas through pipe. A flange pipe is fixedly installed on the top of the cavity. Before the operation, by connecting the coke oven gas pipe to the flange pipe and then opening the valve on the coke oven gas pipe, the coke oven gas will flow along the mixing gas pipe into the gas through pipe and then into the nozzle to provide the coke oven gas and supply certain combustion materials for the combustion of the flame.

[0016] Preferably, a dust filtering orifice plate is fixedly installed on the other side of the cavity, a vertical disk is fixedly installed on the inner wall of the cavity, a rotary cylinder is fixedly installed between the dust filtering orifice plate and the vertical disk, a gas mixing fan is arranged on one side of the vertical disk, the output end of the rotary cylinder penetrates through the inner wall of the vertical disk and is fixedly connected with the gas mixing fan, a plurality of air extraction ports are formed in the inner wall of the vertical disk, a gas mixing and shrinking block is fixedly installed on the inner wall of the cavity, the gas mixing and shrinking block is an arc-shaped ring block and presents a funnel shape. When the coke oven gas enters the cavity, the rotary cylinder drives the gas mixing fan to rotate, the air enters the cavity through the dust filtering orifice plate, and through the rotation of the gas mixing fan, the gas mixing fan drives the two airflows to rotate and move forward together, and finally flows into the gas mixing pipe. The wind force can drive the mixing of the coke oven gas and the air to make the distribution more uniform. The setting of the dust filtering orifice plate is to prevent dust from mixing into the air mixed with the coke oven gas. When the air passes through the dust filtering orifice plate, the air flows into the cavity from the plurality of air extraction ports to provide a certain amount of air for the mixing of the coke oven gas and the air. During operation, the shape of the gas mixing and shrinking block is set so that when the gas mixing fan blows the air, the mixed coke oven gas and air will enter the gas mixing pipe from large to small. Since the larger the diameter of the air flow strand, the more difficult the mixing is, dividing the air flow into many fine strands can increase the contact area between the gas and the air, thereby enhancing the mixing effect.

[0017] Preferably, a plurality of round rods are fixedly installed on the inner wall of the gas mixing pipe, a gas blocking plate is slidably connected to the inner walls of the plurality of round rods, and the plurality of gas blocking plates are slidably and fittingly connected to the inner wall of the gas mixing pipe. A return plate spring is arranged between the gas blocking plate and the round rod. A plurality of notches are formed in the inner wall of the gas mixing pipe. When the mixed air flow enters the gas mixing pipe, the air flow pushes the gas blocking plate to squeeze the return plate spring and slide in the round rod. When the gas blocking plate slides to a certain position, the notches in the gas mixing pipe will be opened. Through the limiting setting of the gas blocking plate, the flow direction of the air flow is changed, so that the air flow changes from a direct flow to an oblique flow state. Cooperating with the pipe wall of the gas mixing pipe, when the air flow flows in the gas mixing pipe, it will be continuously impacted, thereby improving the mixing degree of the two gases and enabling the coke oven gas to burn fully when burning.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For a long-flame windproof burner and a coke oven gas burner according to the present invention, when the flame burns continuously, the wire mesh on the top of the windproof cover will be heated and turn red due to the temperature of the flame. The setting of the windproof cover can effectively avoid the influence of external factors such as wind, which is more conducive to the combustion of the flame inside the windproof cover. When the gas pressure fluctuates and causes the flame to go out, since the ignition temperature of the coke oven gas is about 600 degrees and the temperature of the red-hot wire is above 700 degrees, the temperature of the wire can ignite the coke oven gas, ensuring the stability of the long flame.

[0020] 2. The long-open flame windproof burner and coke oven gas burner described in the present invention use the convection movement caused by the heat generated during the combustion process and the gas expansion. This convection movement maintains the flame in an upward shape, and also forms a surging airflow phenomenon under the flame. Therefore, when the cylinder is placed in the air, air flows into the cylinder from the air inlet hole, and the inner air flowing into the cylinder flows upward along the opening between the air duct and the inclined ladder block. Since the opening between the air duct and the inclined ladder block is an annular opening and the upper part of the inclined ladder block is an arc slope, the turbulent nature of the flame can be stably enhanced when the airflow moves upward, and the flame front becomes thicker to form an area, thereby achieving the effect of assisting combustion.

[0021] 3. The ever-open flame windproof burner and coke oven gas burner described in the present invention can separate the wind shield from the cylinder by rotating the wind shield so that the connecting rod on the bottom end of the wind shield is rotated out from the clamping rod and the wind shield is lifted up, so as to facilitate cleaning of the nozzle after the combustion is completed and prevent the nozzle from being blocked by the burning residue, which is not conducive to subsequent combustion.

[0022] 4. The ever-open flame windproof burner and coke oven gas burner described in the present invention, through the airflow pushing the air baffle to squeeze the return plate spring to slide in the round rod, the notch in the mixing pipe will be opened, and the limit setting of the air baffle will change the flow direction of the airflow, so that the airflow is changed from a direct flow to an oblique flow state. In conjunction with the wall of the mixing pipe, the airflow will be continuously impacted when flowing in the mixing pipe, thereby improving the mixing degree of the two gases, so that the coke oven gas can be fully burned during combustion.

[0023] 5. The invention discloses a windproof burner and a coke oven gas burner with a long open flame, which can push two scraper plates, one on the left and one on the right, to move inward, so that the two scraper plates drive the displacement block to slide on the rectangular box. When the two scraper plates move and fit the bottom of the wire mesh, the scraper plates are pressed down to squeeze the cross plate. The cross plate squeezes the pressure-bearing spring in the rectangular box and rotates, so that one end of the scraper plates will be tilted up, so that one end of the scraper plates changes from being placed at the bottom of the wire mesh to being fitted with the bottom of the wire mesh. Then, the scraper plates are pulled, and the two scraper plates will scrape the black solids at the bottom of the wire mesh onto the scraper plates, so as to avoid that the black solids at the bottom of the wire mesh will affect the heat absorption effect of the wire mesh when it is burning, resulting in the ignition temperature of the wire mesh being unable to re-ignite the long open flame when the long open flame is extinguished during the next combustion operation.

[0024] 6. The ever-open flame windproof burner and coke oven gas burner described in the present invention have an inclined surface setting of the scraper board, so that the scraped black solids will slide smoothly into the two ash boxes along the inclined surface of the scraper board, thereby preventing the black solids from falling into the interior of the device when the scraper board is scraping the black solids, thereby affecting the operation of the device.

Detailed implementation mode

[0041] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0042] As Figures 1 to 14 shown, a long-flame windproof burner described in an embodiment of the present invention includes a coke oven gas burner and a long-flame windproof burner. The long-flame windproof burner is arranged at one end of the coke oven gas burner. A wind shield 2 is arranged at one end of the long-flame windproof burner. A plurality of holes 18 are opened in the inner wall of the top end of the wind shield 2. The opening of the plurality of holes 18 can ensure the oxygen required for the combustion of the long flame and form a wind tunnel effect to weaken the wind pressure. A wire mesh 17 is fixedly installed at the top end of the wind shield 2. The wire mesh 17 is arranged directly above the long-flame windproof burner;

[0043] Due to the pressure fluctuation of the self-produced coke oven gas pipeline and the influence of external environmental factors, the long flame often goes out. If the on-site workers do not discover and handle it in time, it will cause gas leakage, thus generating a large safety hazard;

[0044] By connecting the coke oven gas burner with the pilot flame windproof burner, connecting the windproof cover 2 to one end of the pilot flame windproof burner, and then controlling the coke oven gas burner to conduct coal feeding ignition and combustion operation on the pilot flame windproof burner. The setting of the windproof cover 2 can effectively avoid the influence of external factors such as wind, and is more conducive to the combustion of the flame inside the windproof cover 2. Through the continuous combustion of the flame, the wire mesh 17 at the top of the windproof cover 2 will be affected by the temperature of the flame and turn red and heat up. When the gas pressure fluctuates and causes the flame to go out, since the ignition temperature of the coke oven gas is about 600 degrees and the temperature of the red-hot wire is above 700 degrees, the temperature of the wire can ignite the coke oven gas, ensuring the stability of the pilot flame. It can prevent the on-site workers from failing to discover and handle in time, which may lead to gas leakage and pose a greater safety hazard. Here, it should be noted that when the pilot flame is in normal use, the wire mesh 17 remains in a red-hot state due to being baked, with a temperature of 700 - 1250 degrees, which is higher than the ignition temperature of the coke oven gas of 600 degrees. In this way, the three elements of combustion are always satisfied: the ignition source wire mesh 17, the oxygen in the air as the supporter of combustion, and the coke oven gas as the combustible, thus ensuring the stable combustion of the pilot flame.

[0045] As Figures 6 to 7 shown, the pilot flame windproof burner includes a cylinder 1. The inner wall of the cylinder 1 is fixedly installed with a gas pipe 19. The outer wall of the gas pipe 19 is fixedly installed with a controller 21. The top of the gas pipe 19 is fixedly installed with a nozzle 32. A plurality of shunt pipes 24 are fixedly installed between the bottom of the nozzle 32 and the top of the gas pipe 19. An igniter 22 is arranged outside the nozzle 32. The controller 21 and the igniter 22 are connected through a high-temperature resistant conduit line.

[0046] When the coke oven gas is introduced into the gas pipe 19, the coke oven gas placed in the gas pipe 19 is divided into multiple strands and flows into the nozzle 32 in a downstream manner. Subsequently, the controller 21 controls the igniter 22 to ignite the nozzle 32, and the coke oven gas placed in the nozzle 32 will be affected by the igniter 22 and burn, thus achieving the effect of starting a fire. Here, it should be noted that both the controller 21 and the igniter 22 are made of high-temperature resistant materials.

[0047] As Figures 1 to 2 shown, the inner wall of the cylinder 1 is fixedly installed with an air guiding platform 9. The outer walls of the igniter 22 and the controller 21 are fixedly connected to the inner wall of the top end of the air guiding platform 9. A plurality of air inlet holes 6 are opened in the inner wall of the air guiding platform 9. The positions of the plurality of air inlet holes 6 are arranged at one end of the air guiding platform 9. The inner wall of the windproof cover 2 is fixedly installed with an inclined ladder block 20. The installation position of the inclined ladder block 20 is at the other end of the air guiding platform 9. The outer shape of the inclined ladder block 20 is set as an inclined convex shape. An air inlet ring opening is formed between the protruding end of the inclined ladder block 20 and the top end of the air guiding platform 9.

[0048] When the coke oven gas burns in the nozzle 32 at one end inside the cylinder 1, due to the placement of the cylinder 1 in the air, during the combustion process of the flame, the heat generated by combustion and the gas expansion will cause the surrounding air to expand due to heat, forming a density difference. This density difference causes the flame and the surrounding air to generate an upward air current. The gas in the flame expands due to heat, increasing in volume and decreasing in density. At the same time, the heat generated by the flame causes the surrounding air to also expand due to heat. Due to the existence of the density difference, the colder and denser air below the flame will be pushed upward, forming an upward air current. The convective motion caused by the heat and gas expansion generated during the combustion process maintains the flame in an upward shape and also forms a phenomenon of air current surging at the lower part of the flame. Therefore, when the cylinder 1 is placed in the air, air flows into the cylinder 1 through the air inlet hole 6 and flows upward through the opening between the smooth air guiding platform 9 and the inclined ladder block 20 inside the cylinder 1. Since the opening between the air guiding platform 9 and the inclined ladder block 20 is an annular opening and the upper part of the inclined ladder block 20 is an arc-shaped inclined surface, when the air current moves upward, it can stably enhance the turbulent nature of the flame, making the flame front thicker and forming a region, achieving the effect of assisting combustion.

[0049] As Figures 6 to 9 shown, a ring plate 25 is fixedly installed at the top end of the cylinder 1, and a plurality of connecting rods 26 are fixedly installed at the bottom of the wind shield 2. A plurality of slide rod openings 31 are formed at the top of the ring plate 25, and a plurality of rectangular grooves 30 are fixedly installed on the inner wall of the ring plate 25. A plurality of clamping rods 27 are slidably connected to the inner walls of the plurality of rectangular grooves 30. Shaft rods 29 are fixedly installed on the inner walls of the plurality of rectangular grooves 30. A return spring 28 is provided between one side of each of the plurality of clamping rods 27 and the inner wall of each of the plurality of rectangular grooves 30. One end of each of the plurality of clamping rods 27 can be clamped with the inner wall of each of the plurality of connecting rods 26. Force application handles 23 are symmetrically and fixedly installed on the outer wall of the wind shield 2;

[0050] When connecting the wind shield 2 and the cylinder 1, insert the connecting rod 26 at the bottom of the wind shield 2 into the ring plate 25 through the slide rod opening 31. Then, hold the force application handle 23 and rotate the wind shield 2. When the wind shield 2 rotates, it drives the connecting rod 26 to rotate in the slide rod opening 31, and the connecting rod 26 will squeeze the clamping rod 27 to move backward in the rectangular groove 30. When rotating the wind shield 2 to drive the connecting rod 26 to move to a certain position, the clamping rod 27 will be snapped into the connecting rod 26 under the elastic thrust of the return spring 28 for connection and installation. When the device does not need to perform combustion operations, first cool down the wind shield 2, and then rotate the wind shield 2 to rotate the connecting rod 26 at the bottom end of the wind shield 2 out of the clamping rod 27. Then, lift the wind shield 2 to separate the wind shield 2 from the cylinder 1, which is convenient for cleaning the nozzle 32 after combustion to prevent the slag and dirt generated during combustion from blocking the nozzle 32, which is not conducive to subsequent combustion. The setting of the force application handle 23 provides a good force application point for rotating the wind shield 2, making disassembly more convenient.

[0051] As shown Figures 10 to 11 in the figure, a dust removal box 34 is fixedly installed at the top of the wind shield 2. Inside the dust removal box 34, scraping plates 36 are symmetrically arranged. The two scraping plates 36 are slidably connected to the inner wall of the wind shield 2. One end of each of the two scraping plates 36 can scrape at the bottom of the wire mesh 17. On the inner wall of the dust removal box 34, rectangular boxes 38 are symmetrically and fixedly installed. At the bottom of one end of each of the two scraping plates 36, displacement blocks 45 are fixedly installed. The outer walls of the two displacement blocks 45 are respectively slidably connected to the inner walls of the two rectangular boxes 38;

[0052] When a combustion operation is completed, by pushing the two scraping plates 36, one on the left and one on the right, inward, the two scraping plates 36 drive the displacement blocks 45 to slide on the rectangular boxes 38. When the displacement blocks 45 slide to one end of the rectangular boxes 38, at this time, the two scraping plates 36 are attached to the bottom of the wire mesh 17. Then, by pulling the two scraping plates 36 to open to both sides, one end of the two scraping plates 36 will scrape at the bottom of the wire mesh 17, scraping off the black solids generated at the bottom of the wire mesh 17 during combustion, preventing the excessive black solids at the bottom of the wire mesh 17 during combustion from affecting the heat absorption effect of the wire mesh 17, resulting in the ignition temperature of the wire mesh 17 being unable to re-ignite the long flame when the long flame goes out during the next combustion operation.

[0053] As shown Figures 11 to 12 in the figure, a cross plate 39 is rotatably connected to the inner wall of the rectangular box 38. Between the bottom of the cross plate 39 and the bottom of the inner wall of the rectangular box 38, a plurality of pressure-bearing springs 40 are arranged. The bottom of the displacement block 45 is slidably connected to the top of the cross plate 39. Ash disposal boxes 35 are symmetrically arranged on both sides of the rectangular box 38;

[0054] When the two scraping plates 36 are attached to the bottom of the wire mesh 17, by pressing down the scraping plates 36, the scraping plates 36 will squeeze the cross plate 39 in the rectangular box 38 through the displacement blocks 45. When the cross plate 39 squeezes the pressure-bearing springs 40 and rotates in the rectangular box 38, the displacement blocks 45 will move downward, and one end of the scraping plates 36 will tilt up, so that one end of the scraping plates 36 changes from the state of being placed at the bottom of the wire mesh 17 to the state of being attached to the bottom of the wire mesh 17. Then, by pulling the scraping plates 36, the two scraping plates 36 will scrape the black solids at the bottom of the wire mesh 17 onto the scraping plates 36. Through the inclined surface setting of the scraping plates 36, the scraped black solids will smoothly slide into the two ash disposal boxes 35 along the inclined surfaces of the scraping plates 36, preventing the black solids from falling into the device during the scraping of the black solids, which affects the operation of the device.

[0055] As shown Figures 13 to 14As shown in the figure, fire baffle rods 37 are symmetrically and slidably connected to the inner wall of the ash removal box 34. The two fire baffle rods 37 can respectively slide on the top of the two ash scraping plates 36 and the inner wall of the wind shield 2. Slide sleeves 41 are symmetrically and fixedly installed on the inner wall of the ash removal box 34. Shafts 42 are symmetrically and slidably connected to the inner walls of the two slide sleeves 41. Two card slots 43 are symmetrically formed on the inner walls of the two fire baffle rods 37. One ends of multiple shafts 42 can respectively be clamped with the inner walls of multiple card slots 43. A push shaft spring 44 is arranged between the inner wall of the slide sleeve 41 and one end of the shaft 42;

[0056] When a combustion operation is completed, by pulling the fire baffle rods 37, the two fire baffle rods 37 slide out from between the top of the ash scraping plate 36 and the inner wall of the wind shield 2. During the sliding, the inner side of the fire baffle rod 37 squeezes the shaft 42 to slide. When the fire baffle rod 37 completely moves away from the top of the ash scraping plate 36, the card slot 43 at one end of the fire baffle rod 37 will move to the position of the shaft 42. Through the elastic thrust of the push shaft spring 44, one end of the shaft 42 will be clamped into the card slot 43, so as to open the opening between the top of the ash scraping plate 36 and the inner wall of the wind shield 2, facilitating the subsequent ash removal operation of the ash scraping plate 36. When the ash removal operation of the ash scraping plate 36 is completed, by pushing the fire baffle rod 37 back to its original position, the shaft 42 will be re-clamped into the card slot 43 at the other end of the fire baffle rod 37 for limiting, so that the fire baffle rod 37 fills the gap between the top of the ash scraping plate 36 and the inner wall of the wind shield 2, preventing the long flame from burning into the interior of the ash removal box 34 during the combustion operation and damaging the internal structure of the ash removal box 34. It should be noted here that both the ash scraping plate 36 and the fire baffle rod 37 are made of high-temperature resistant materials.

[0057] A coke oven gas burner, which adopts the above-mentioned long flame windproof burner, includes a cavity 4. The cavity 4 is fixedly installed at one end of the cylinder 1. A mixing gas pipe 8 is fixedly installed on one side of the cavity 4. The mixing gas pipe 8 is placed inside the cylinder 1. One end of the mixing gas pipe 8 is fixedly connected to the gas pipe 19. A flange pipe 3 is fixedly installed on the top of the cavity 4;

[0058] Before the operation, by connecting the coke oven gas pipe to the flange pipe 3, and then opening the valve on the coke oven gas pipe, the coke oven gas will flow into the gas pipe 19 along the mixing gas pipe 8, and then into the nozzle 32, providing the coke oven gas and providing certain combustion materials for the combustion of the flame. It should be noted here that the coke oven gas pipe and the valve are both prior arts and are not described in this technical solution.

[0059] As Figures 1 to 3As shown in the figure, a dust filtering orifice plate 5 is fixedly installed on the other side of the cavity 4, a vertical disk 13 is fixedly installed on the inner wall of the cavity 4, a rotary cylinder 10 is fixedly installed between the dust filtering orifice plate 5 and the vertical disk 13, a mixing air fan 11 is arranged on one side of the vertical disk 13, and the output end of the rotary cylinder 10 penetrates through the inner wall of the vertical disk 13 and is fixedly connected with the mixing air fan 11. A plurality of air extraction ports 12 are formed in the inner wall of the vertical disk 13, and a mixing and shrinking block 7 is fixedly installed on the inner wall of the cavity 4. The mixing and shrinking block 7 is an arc-shaped ring block and presents a funnel shape.

[0060] By externally connecting an air suction valve outside the dust filtering orifice plate 5, when the coke oven gas enters the cavity 4, the rotary cylinder 10 drives the mixing air fan 11 to rotate. When the air passes through the dust filtering orifice plate 5, the air flows into the cavity 4 from a plurality of air extraction ports 12, providing a certain amount of air for the mixing of the coke oven gas and the air. Through the rotation of the mixing air fan 11, the mixing air fan 11 will drive the two airflows to rotate and move forward together, and finally flow into the mixing gas pipe 8 through the mixing and shrinking block 7. The wind force can drive the mixing of the coke oven gas and the air, making their distribution more uniform. The setting of the dust filtering orifice plate 5 is to prevent dust from mixing into the air mixed with the coke oven gas. The shape of the mixing and shrinking block 7 is set so that when the mixing air fan 11 blows the air, the mixed coke oven gas and air will enter the mixing gas pipe 8 from large to small. Since the larger the diameter of the air flow stream, the more difficult the mixing is, dividing the air flow into many fine strands can increase the contact area between the gas and the air, thereby increasing the mixing effect. Here, it should be noted that the aperture of the air extraction port 12 needs to be obtained through actual measurement.

[0061] As Figures 4 to 5 As shown in the figure, a plurality of round rods 15 are fixedly installed on the inner wall of the mixing gas pipe 8. A baffle plate 14 is slidably connected to the inner walls of the plurality of round rods 15. The plurality of baffle plates 14 are all slidably connected to the inner wall of the mixing gas pipe 8 in a fitting manner. A return spring 16 is arranged between the baffle plate 14 and the round rod 15. A plurality of notches 33 are formed in the inner wall of the mixing gas pipe 8.

[0062] When the mixed air flow enters the mixing gas pipe 8, the air flow pushes the baffle plate 14 to squeeze the return spring 16 and slide in the round rod 15. When the baffle plate 14 slides to a certain position, the notch 33 in the mixing gas pipe 8 will be opened. Through the limit setting of the baffle plate 14, the flow direction of the air flow is changed, so that the air flow changes from a direct flow to an oblique flow state. Cooperating with the pipe wall of the mixing gas pipe 8, when the air flow flows in the mixing gas pipe 8, it will be continuously impacted, thereby improving the mixing degree of the two gases and enabling the coke oven gas to burn sufficiently when burning.

[0063] Working principle: By connecting the coke oven gas burner with the pilot burner with wind protection, connecting the wind protection cover 2 to one end of the pilot burner with wind protection, and then controlling the coke oven gas burner to supply coal and ignite the pilot burner with wind protection for combustion operation. The setting of the wind protection cover 2 can effectively avoid the influence of external factors such as wind, which is more conducive to the combustion of the flame inside the wind protection cover 2. Through the continuous combustion of the flame, the wire mesh 17 at the top of the wind protection cover 2 will be affected by the temperature of the flame and turn red and heat up. When the flame goes out due to the fluctuation of the gas pressure, since the ignition temperature of the coke oven gas is about 600 degrees and the temperature of the red-hot wire is above 700 degrees, the temperature of the wire can ignite the coke oven gas, ensuring the stability of the pilot flame, preventing the on-site workers from failing to detect and handle in time, which may lead to gas leakage and pose a greater safety hazard. Here, it should be noted that when the pilot flame is in normal use, the wire mesh 17 remains in a red-hot state due to being baked, with a temperature of 700 - 1250 degrees, which is higher than the ignition temperature of the coke oven gas of 600 degrees. In this way, the three elements of combustion are always satisfied: the ignition source wire mesh 17, the oxygen in the air as the combustion-supporting substance, and the coke oven gas as the combustible substance, thus ensuring the stable combustion of the pilot flame;

[0064] When the coke oven gas is introduced into the gas pipe 19, the coke oven gas placed in the gas pipe 19 is divided into multiple strands and flows into the nozzle 32 in a downstream manner. Then, the controller 21 controls the igniter 22 to ignite the nozzle 32, and the coke oven gas placed in the nozzle 32 will be affected by the igniter 22 and burn, thus achieving the effect of starting a fire;

[0065] When the coke oven gas burns in the nozzle 32 at one end of the cylinder 1, due to the placement of the cylinder 1 in the air, during the combustion process of the flame, the heat and gas expansion generated by the combustion will cause the surrounding air to expand due to heat, forming a density difference. This density difference causes the flame and the surrounding air to generate an upward airflow. The gas in the flame expands due to heat, its volume increases, and its density decreases. At the same time, the heat generated by the flame also causes the surrounding air to expand due to heat. Due to the existence of the density difference, the colder and denser air below the flame will be pushed upward, forming an upward airflow. The convective motion caused by the heat and gas expansion during the combustion process makes the flame maintain an upward shape, and at the same time, it also forms a phenomenon of airflow surging at the lower part of the flame. Therefore, when the cylinder 1 is placed in the air, the air flows into the cylinder 1 from the air inlet hole 6 and flows upward through the opening between the smooth air guiding platform 9 and the inclined ladder block 20. Since the opening between the air guiding platform 9 and the inclined ladder block 20 is an annular opening and the upper part of the inclined ladder block 20 is an arc-shaped inclined surface, when the airflow moves upward, it can stably enhance the turbulent nature of the flame, making the flame front thicker, forming a region, and achieving the effect of assisting combustion;

[0066] When connecting the wind shield 2 to the cylinder 1, insert the connecting rod 26 at the bottom of the wind shield 2 into the annular disc 25 through the slide rod opening 31. Then, hold the force - applying handle 23 and rotate the wind shield 2. When the wind shield 2 rotates, it drives the connecting rod 26 to rotate within the slide rod opening 31. The connecting rod 26 will then squeeze the latch rod 27 to move backward within the rectangular groove 30. When rotating the wind shield 2 to drive the connecting rod 26 to move to a certain position, the latch rod 27 will be snapped into the connecting rod 26 under the elastic thrust of the return spring 28 for connection and installation. When the device does not need to perform combustion operations, first cool down the wind shield 2, and then rotate the wind shield 2 so that the connecting rod 26 at the bottom end of the wind shield 2 rotates out of the latch rod 27. Then, lift the wind shield 2 to separate the wind shield 2 from the cylinder 1, which is convenient for cleaning the nozzle 32 after combustion and prevents the slag and dirt generated during combustion from blocking the nozzle 32, which is not conducive to subsequent combustion. The setting of the force - applying handle 23 provides a good force - applying point for rotating the wind shield 2, making disassembly more convenient;

[0067] When a combustion operation is completed, push the two ash - scraping plates 36, one on the left and one on the right, inward so that the two ash - scraping plates 36 drive the displacement blocks 45 to slide on the rectangular box 38. When the displacement blocks 45 slide to one end of the rectangular box 38, at this time, the two ash - scraping plates 36 are placed in contact with the bottom of the wire mesh 17. Then, press and pull the two ash - scraping plates 36 to open them to both sides. One end of the two ash - scraping plates 36 will scrape at the bottom of the wire mesh 17, scraping off the black solids generated at the bottom of the wire mesh 17 during combustion, avoiding excessive black solids at the bottom of the wire mesh 17 during combustion from affecting the heat - absorption effect of the wire mesh 17, resulting in the ignition temperature of the wire mesh 17 being unable to re - ignite the long - lasting flame when the long - lasting flame goes out during the next combustion operation;

[0068] When the two ash - scraping plates 36 are placed in contact with the bottom of the wire mesh 17, by pressing down the ash - scraping plates 36, the ash - scraping plates 36 will squeeze the cross - plate 39 in the rectangular box 38 through the displacement blocks 45. When the cross - plate 39 squeezes the pressure - bearing spring 40 in the rectangular box 38 and rotates, the displacement blocks 45 will move downward, and one end of the ash - scraping plates 36 will tilt up, so that one end of the ash - scraping plates 36 changes from the state of being placed at the bottom of the wire mesh 17 to the state of being in contact with the bottom of the wire mesh 17. Then, pull the ash - scraping plates 36, and the two ash - scraping plates 36 will scrape the black solids at the bottom of the wire mesh 17 onto the ash - scraping plates 36. Through the inclined - plane setting of the ash - scraping plates 36, the scraped - off black solids will slide smoothly along the inclined plane of the ash - scraping plates 36 into the two ash - holding boxes 35, avoiding the black solids falling into the interior of the device when the ash - scraping plates 36 scrape off the black solids, which affects the operation of the device;

[0069] When a combustion operation is completed, by pulling the fire baffle rod 37, the two fire baffle rods 37 slide out from between the top of the ash scraping plate 36 and the inner wall of the wind shield 2. During the sliding, the inner side of the fire baffle rod 37 squeezes the clamping shaft 42 to slide. When the fire baffle rod 37 completely moves away from the top of the ash scraping plate 36, the card slot 43 at one end of the fire baffle rod 37 will move to the position of the clamping shaft 42. Through the elastic thrust of the push shaft spring 44, one end of the clamping shaft 42 will be stuck into the card slot 43, so as to open the opening between the top of the ash scraping plate 36 and the inner wall of the wind shield 2, facilitating the subsequent ash removal operation of the ash scraping plate 36. When the ash removal operation of the ash scraping plate 36 is completed, by pushing the fire baffle rod 37 to reset, the clamping shaft 42 will be re-stuck into the card slot 43 at the other end of the fire baffle rod 37 for limiting, so that the fire baffle rod 37 backfills the gap between the top of the ash scraping plate 36 and the inner wall of the wind shield 2, preventing the long flame from burning into the inside of the ash removal box 34 during the combustion operation and damaging the internal structure of the ash removal box 34;

[0070] Before the operation, by connecting the coke oven gas pipe to the flange pipe 3, and then opening the valve on the coke oven gas pipe, the coke oven gas will flow into the gas pipe 19 along the mixing gas pipe 8, and then into the nozzle 32, providing coke oven gas and providing certain combustion materials for the combustion of the flame;

[0071] By externally connecting an air suction valve outside the dust filtering orifice plate 5, when the coke oven gas enters the cavity 4, the rotary cylinder 10 drives the mixing gas fan 11 to rotate. When the air passes through the dust filtering orifice plate 5, the air flows into the cavity 4 from multiple air extraction ports 12, providing certain air for the mixing of the coke oven gas and the air. Through the rotation of the mixing gas fan 11, the mixing gas fan 11 will drive the two airflows to rotate and move forward together, and finally flow into the mixing gas pipe 8 through the mixing contraction block 7. The wind force can drive the mixing of the coke oven gas and the air, making their distribution more uniform. The setting of the dust filtering orifice plate 5 is to prevent dust from mixing into the air mixed with the coke oven gas. The shape of the mixing contraction block 7 is set so that when the mixing gas fan 11 blows the air, the mixed coke oven gas and air will flow into the mixing gas pipe 8 from large to small. Since the larger the diameter of the air flow strand, the more difficult the mixing is, dividing the air flow into many fine strands can increase the contact area between the gas and the air, thereby increasing the mixing effect;

[0072] When the mixed air flow enters the mixing gas pipe 8, the air flow pushes the air baffle 14 to squeeze the return plate spring 16 and slide in the round rod 15. When the air baffle 14 slides to a certain position, the notch 33 in the mixing gas pipe 8 will be opened. Through the limit setting of the air baffle 14, the flow direction of the air flow is changed, so that the air flow changes from a direct flow to an oblique flow state. Cooperating with the pipe wall of the mixing gas pipe 8, when the air flow flows in the mixing gas pipe 8, it will be continuously impacted, thereby improving the mixing degree of the two gases and enabling the coke oven gas to burn fully during combustion.
