Description

Technical Field

[0001] The invention relates to the field of incineration equipment, in particular to a multifunctional burner. Background Art

[0002] Burners are widely used in industrial boilers, power generation systems, heating equipment and other fields. Their main function is to efficiently mix fuel and air and ignite them to generate stable heat energy. In response to the trend of energy diversification, existing technologies have developed burners that support multiple fuels, such as composite burners that can process both fuel oil and pulverized coal.

[0003] This type of equipment aims to achieve fuel switching or mixed combustion through structural optimization, thereby improving energy utilization and equipment adaptability. However, existing multi-functional burners still face significant challenges when operating pulverized coal and fuel oil in synergy: pulverized coal is prone to agglomeration due to factors such as humidity and static electricity during transportation, resulting in some pulverized coal not being fully burned after being ejected; during the fuel oil atomization process, larger droplets are difficult to ignite due to insufficient kinetic energy, resulting in resource waste and environmental pollution.

[0004] The core problem of existing multifunctional burners lies in the deficiencies in the fuel processing link. First, the agglomeration of coal powder not only reduces combustion efficiency, but also increases the emission of unburned coal powder, requiring additional separation and reprocessing equipment. Second, insufficient fuel atomization leads to uneven droplet size distribution, and larger droplets cannot be completely burned. Existing equipment lacks the function of capturing and re-atomizing unburned fuel, which directly causes fuel waste.

[0005] Traditional structures make it difficult to achieve integrated coordination of coal powder crushing, fuel atomization and recovery and reuse, resulting in high equipment complexity and increased maintenance costs. Therefore, there is an urgent need for a multifunctional burner that integrates efficient fuel processing and recovery mechanisms to solve the above technical bottlenecks and improve the comprehensive energy efficiency and environmental protection performance of multi-fuel combustion.

[0014] As a preferred technical solution of the present invention, the reprocessing assembly includes two scraper members that are slidably arranged on the inner side of the fixed pipe rack. The right side of the scraper member is affixed to the annular filter plate, and the inner side of the fixed pipe rack is provided with a plurality of rotating grinding roller members that are evenly spaced along its circumference and match the shape of the inner side of the rotating ring.

[0017] As a preferred technical solution of the present invention, the spreading assembly includes a U-shaped frame fixedly installed on the inner side of the fixed pipe rack, and a side wall of the U-shaped frame with the same rotation direction as the slewing ring is attached to the inner side of the slewing ring. The middle part of the U-shaped frame is a structure that gradually tilts downward from left to right, and a shaking plate is slidably provided on the inclined structure of the U-shaped frame.

[0018] As an optimal technical solution of the present invention, a powder-raising plate is hinged on the right side of the U-shaped frame inclined structure, a linkage column is fixedly installed on the left side of the powder-raising plate, and a linkage plate is fixedly installed on the right side of the shaking plate. An inclined waist-shaped groove is provided on the linkage plate, and the linkage column is inserted into the waist-shaped groove.

[0019] The beneficial effects of the present invention are: 1. The present invention adopts the synergistic effect of the annular filter plate in the coal crushing mechanism and the reprocessing component to capture unburned coal powder particles in real time. The V-shaped inner side surface of the rotating ring can collect the captured coal powder and further crush the agglomerated coal powder through the rolling of the grinding roller. The crushed coal powder is then evenly spread into the combustion area through the spreading component, which significantly improves the secondary combustion rate of the coal powder and reduces the emission of unburned coal powder.

[0020] 2. The present invention adopts an atomizing mechanism to scoop up larger and unburned fuel droplets sprayed out through a specific angle of the oil shoveling plate. While transporting the fuel droplets through the guide component, the spiral plate structure of the oil guide ring is used to impact the enlarged fuel droplets, thereby further atomizing the fuel droplets. The fuel droplets then collide and deflect in the annular reflection bowl, and the larger droplets are atomized for the second time while being guided to the combustion zone, so that the unburned fuel can be recycled and then re-combusted, significantly reducing the particle size distribution range of the fuel droplets, improving the uniformity of atomization, and reducing the waste and pollution of unburned fuel.

[0021] 3. The present invention adopts a conversion unit through a linkage design of a switching frame and a transmission shaft to realize the rapid switching operation of the coal crushing mechanism and the atomization mechanism. When the reprocessing component scrapes the coal powder on the annular filter plate, it can also prevent the coal powder from adhering to and clogging the annular filter plate by knocking the annular filter plate. While ensuring the passability of the annular filter plate, it can ensure that the agglomerated coal powder is moved to the position of the grinding roller for crushing.

[0022] 4. When the present invention uses a grinding roller to crush the coal powder on the inner side of the rotating ring, the grinding roller can swing the impact piece to the outside of the grinding roller under the action of centrifugal force, so that the impact piece collides with the coal powder, and the guide groove can also drive the impact piece to reciprocate and crush the coal powder, thereby further improving the crushing effect.

[0023] 5. The present invention adopts a shaking plate to reciprocately shake the coal powder blocked by the U-shaped frame, so that the coal powder is evenly arranged on the shaking plate, so that the coal powder is scattered when falling into the combustion zone, so that the coal powder after re-crushing can be fully burned, and the shaking plate and the powder raising plate can intermittently lift the falling coal powder, further increasing the dispersion of the coal powder when falling.

[0037] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0038] See Figure 1 A multifunctional burner includes a burner body 1, to which a coal crushing mechanism 2 for capturing and reprocessing coal powder and an atomizing mechanism 3 for capturing and further atomizing fuel are connected through a conversion unit 11.

[0039] When the burner body 1 needs to work, the coal crushing mechanism 2 or the atomizing mechanism 3 is selected through the conversion unit 11 according to the combustion source and moved to the nozzle position of the burner body 1. The coal crushing mechanism 2 can capture the agglomerated unburned coal powder, and then crush the coal powder. Thereafter, the crushed coal powder is sprinkled again at the nozzle position of the burner body 1, so that the crushed coal powder can participate in the combustion again. The atomizing mechanism 3 can shovel the unburned large-diameter fuel droplets into its interior, further atomize the larger-diameter fuel droplets through two impacts, and then guide the re-atomized fuel droplets to the nozzle position of the burner body 1, so that it can participate in the combustion again.

[0040] See Figure 1 、 Figure 2 and Figure 3 The coal crushing mechanism 2 includes a fixed pipe rack 21 arranged on the conversion unit 11, and a slewing ring 22 is rotatably arranged on the right side of the fixed pipe rack 21. An annular filter plate 23 for capturing unburned coal powder is fixedly installed on the right side of the slewing ring 22. The coal crushing mechanism 2 also includes a reprocessing component 24 and a spreading component 25. The inner side surface of the slewing ring 22 is a V-shaped structure. The reprocessing component 24 scrapes the coal powder on the annular filter plate 23 and then further crushes the coal powder. The crushed coal powder is then evenly spread through the spreading component 25 so that the crushed coal powder can participate in combustion again.

[0041] See Figure 1 、 Figure 10 and Figure 11 The atomization mechanism 3 includes an oil suction pipe 31 arranged on the right side surface of the conversion unit 11. A plurality of oil shovel plates 32 are arranged on the right side surface of the oil suction pipe 31 at equal intervals along its circumference. The length direction of the oil shovel plates 32 forms an angle with the radial direction of the oil suction pipe 31. The atomization mechanism 3 also includes a guide component 33 for further atomizing the misted fuel sucked into the oil suction pipe 31 by the oil shovel plates 32 through impact action, and then guiding it back for reburning.

[0042] See Figure 1 The conversion unit 11 includes a fixed support plate 111 fixedly installed on the outside of the nozzle of the burner body 1, and a switching frame 112 is rotatably provided on the upper side of the fixed support plate 111. The switching frame 112 is locked on the fixed support plate 111 by a positioning pin. The right part of the switching frame 112 has a double-ring structure. The fixed pipe rack 21 is coaxially fixedly connected to one ring structure of the switching frame 112, and the oil suction pipe 31 is coaxially rotatably connected to the other ring structure of the switching frame 112.

[0043] When the burner body 1 is required to work, if the fuel source used by the burner body 1 is pulverized coal, the operator manually rotates the switching frame 112 in advance, so that the switching frame 112 drives the oil suction pipe 31 and the fixed pipe rack 21 to rotate to an upper and lower arrangement, and the oil suction pipe 31 is on the top and the fixed pipe rack 21 is on the bottom. Then the operator locks the switching frame 112 and the fixed support plate 111 into a whole through the positioning pin.

[0044] It should be noted that if Figure 2 、 Figure 9 and Figure 10 As shown, the interior of the fixed pipe rack 21 and the interior of the oil suction pipe fitting 31 are both provided with joint pipes for docking with the nozzle of the burner body 1. The joint pipe inside the fixed pipe rack 21 is fixedly connected to the fixed pipe rack 21, and the joint pipe inside the oil suction pipe fitting 31 is fixedly connected to the switching rack 112.

[0045] When the switching frame 112 and the fixed support plate 111 are locked into a whole, the switching frame 112 drives the joint pipe inside it to fit on the right side of the nozzle of the burner body 1 through the fixed pipe rack 21, and makes the joint pipe inside the fixed pipe rack 21 coaxially arranged with the nozzle of the burner body 1.

[0046] See Figure 1 、 Figure 2 and Figure 9 A transmission shaft 113 is rotatably provided inside the switching frame 112 and located on its rotation axis. A driving gear 114 is fixedly installed on the right end of the transmission shaft 113. A driven gear 115 meshing with the driving gear 114 is installed on the outer side of the slewing ring 22 and the oil suction pipe 31. An asynchronous motor 116 is fixedly installed on the burner body 1, and the output shaft of the asynchronous motor 116 is fixedly connected to the left end of the transmission shaft 113.

[0047] When the burner body 1 is working, the agglomerated unburned coal powder is ejected from the nozzle of the burner body 1, and the coal powder passes through the joint pipe at the corresponding position and moves to the left side of the annular filter plate 23, so that the annular filter plate 23 captures the unburned coal powder. Then, the asynchronous motor 116 is started to drive the driving gear 114 to rotate through the transmission shaft 113, and the driving gear 114 drives the slewing ring 22 and the oil suction pipe 31 to rotate synchronously through the driven gear 115.

[0048] The rotating ring 22 drives the captured coal powder on it to rotate synchronously through the annular filter plate 23. The coal powder that does not adhere to the annular filter plate 23 falls to the V-shaped inner side surface of the rotating ring 22 under the action of gravity. The inner side surface of the rotating ring 22 guides the coal powder, so that the coal powder is gathered in the middle position of the rotating ring 22, which makes it easier to centrally crush the coal powder.

[0049] See Figure 2 、 Figure 3 and Figure 4 The reprocessing assembly 24 includes two scraper members 241 that are slidably arranged on the inner side of the fixed pipe rack 21. The right side of the scraper member 241 is attached to the annular filter plate 23. The inner side of the fixed pipe rack 21 is provided with a plurality of rotatable grinding roller members 242 that are equidistant along its circumference and match the shape of the inner side of the rotating ring 22.

[0050] Continue reading Figure 2 、 Figure 3 and Figure 4A coil spring is provided between the scraper member 241 and the fixed pipe frame 21 to push it to the right. The scraper member 241 is arranged at an angle. A hammer column 243 for striking the annular filter plate 23 is fixedly installed on the inclined surface of the scraper member 241 facing the annular filter plate 23. Wedge blocks 244 for pushing the scraper member 241 to the left are fixedly installed at equal intervals along the circumference of the left side edge of the annular filter plate 23.

[0051] The coal powder adhered to the annular filter plate 23 moves to the position of the scraper member 241 as the annular filter plate 23 rotates, so that the scraper member 241 scrapes the left side of the annular filter plate 23, thereby scraping the coal powder adhered to the left side of the annular filter plate 23 and dropping it onto the rotating ring 22. At the same time, the rotating ring 22 synchronously collects the scraped coal powder.

[0052] When the annular filter plate 23 rotates, it drives the wedge block 244 on it to rotate synchronously. When the wedge block 244 moves to the position of the scraper member 241, the wedge block 244 can push the scraper member 241 to the left, so that the scraper member 241 drives the hammer column 243 on it away from the annular filter plate 23, and at the same time compresses the coil spring at the corresponding position. When the wedge block 244 moves to a position beyond the scraper member 241, the coil spring pushes the scraper member 241 through its own elastic force to drive the hammer column 243 to hit the annular filter plate 23, causing the annular filter plate 23 to vibrate. In this way, the coal powder stuck in the sieve holes of the annular filter plate 23 is shaken off onto the rotary ring 22, which can not only ensure the passability of the annular filter plate 23, but also prevent the coal powder from being missed.

[0053] In this embodiment, when a wedge block 244 pushes one of the scraper members 241, the other scraper member 241 is located between two adjacent wedge blocks 244, so that the two scraper members 241 are pushed alternately to ensure the scraping effect of the scraper members 241 on the annular filter plate 23, thereby preventing the two scraper members 241 from not contacting the annular filter plate 23 at the same time, resulting in missed scraping.

[0054] It should be noted that an annular internal gear is fixedly installed on the left end of the inner side surface of the rotating ring 22, and a rotating gear meshing with the annular internal gear is fixedly installed on the grinding roller 242. When the rotating ring 22 rotates, the rotating ring 22 drives all the grinding rollers 242 to rotate synchronously through the annular internal gear and the rotating gear, so that the grinding rollers 242 crush the coal powder driven to the corresponding position by the rotating ring 22 through their outer side.

[0055] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6An impact piece 245 is provided in the middle of the grinding roller 242 for radial sliding movement. A push spring is provided between the impact piece 245 and the grinding roller 242. The outer shape of the impact piece 245 matches the inner surface shape of the rotating ring 22. A fixed column 246 is fixedly installed on the inner surface of the fixed pipe frame 21 and is inserted into the axial position inside the grinding roller 242. A guide groove 247 is provided on the fixed column 246 to push the impact piece 245 away from the inner surface of the rotating ring 22.

[0056] It should be noted that if Figure 6 As shown, the guide groove 247 is an annular structure coaxial with the fixed column 246, and a plurality of pushing teeth are fixedly installed at equal intervals along the circumference of the guide groove 247 on the side of the guide groove 247 away from the axis of the rotating ring 22, and a protruding column sliding inside the guide groove 247 is fixedly installed on the impact member 245. When the powder grinding roller 242 drives the impact member 245 to rotate to the side close to the axis of the rotating ring 22, the powder grinding roller 242 pushes the impact member 245 to extend to the outside of the powder grinding roller 242 through centrifugal force and the elastic force of the push spring. At this time, the impact member 245 drives the protruding column thereon to move along the outer wall of the guide groove 247.

[0057] The grinding roller 242 drives the impact member 245 to impact the coal powder on the inner side of the rotating ring 22, thereby increasing the crushing effect of the coal powder. When the impact member 245 rotates to the side away from the axis of the rotating ring 22, the raised column contacts the pushing teeth, so that the pushing teeth intermittently push the raised column toward the side close to the axis of the rotating ring 22, thereby causing the impact member 245 to intermittently move toward the direction close to the axis of the rotating ring 22, and then the elastic force of the pushing spring pushes the impact member 245 to impact the coal powder, thereby impacting and vibrating the coal powder to crush it. Through the synergistic effect of the three methods of grinding, impacting and vibrating, the re-crushing effect of the agglomerated coal powder is guaranteed.

[0058] See Figure 2 、 Figure 3 and Figure 7 The spreading assembly 25 includes a U-shaped frame 251 fixedly installed on the inner side of the fixed pipe frame 21. The side wall of the U-shaped frame 251, which has the same rotation direction as the slewing ring 22, is attached to the inner side of the slewing ring 22. The middle part of the U-shaped frame 251 is a structure that gradually tilts downward from left to right. A shaking plate 252 is slidably provided on the inclined structure of the U-shaped frame 251.

[0059] See Figure 3 、 Figure 7 and Figure 8 The right side of the U-shaped frame 251 inclined structure is hinged with a powder-raising plate 253, the left side of the powder-raising plate 253 is fixedly installed with a linkage column 254, and the right side of the shaking plate 252 is fixedly installed with a linkage plate 255. The linkage plate 255 is provided with an inclined waist-shaped groove, and the linkage column 254 is inserted into the waist-shaped groove.

[0060] While the grinding roller 242 crushes the coal powder on the rotating ring 22, the continuously rotating rotating ring 22 causes the coal powder on it to press against its inner side surface through centrifugal force, so that the rotating ring 22 drives the crushed coal powder to the position of the U-shaped frame 251. The U-shaped frame 251 scrapes the coal powder on the rotating ring 22 and drops it onto the shaking plate 252 through its side wall attached to the inner side surface of the rotating ring 22.

[0061] It should be noted that if Figure 7 As shown, a transmission gear meshing with the annular internal gear is rotatably provided on the left side of the U-shaped frame 251. The eccentric position of the transmission gear is hinged to the shaking plate 252 through a connecting rod, so that the transmission gear, the connecting rod and the shaking plate 252 are combined to form a crank rocker mechanism, so that the annular internal gear drives the shaking plate 252 to swing back and forth, and then the shaking plate 252 shakes the coal powder falling thereon to a uniform arrangement, thereby increasing the dispersion of the coal powder, preventing the coal powder from agglomerating again, and increasing the area of ​​contact between the coal powder and the air, thereby ensuring the combustion efficiency of the coal powder.

[0062] When the shaking plate 252 moves back and forth, it drives the linkage plate 255 to move synchronously. The linkage plate 255 drives the linkage column 254 to move back and forth up and down through the waist-shaped groove thereon, so that the linkage column 254 drives the powder-raising plate 253 to move back and forth up and down, thereby intermittently lifting the coal powder that slides down the shaking plate 252 to the position of the powder-raising plate 253, further increasing the dispersion of the coal powder, and then the coal powder falls to the corresponding position of the joint pipe to participate in combustion again.

[0063] See Figure 1 、 Figure 9 、 Figure 10 and Figure 11 The guide assembly 33 includes an oil guide ring 331 rotatably arranged on the inner side of the oil suction pipe 31. The outer side of the oil guide ring 331 is a spiral plate structure arranged at equal intervals along its circumference. The oil guide ring 331 is provided with a through hole corresponding to the spiral plate structure. The interior of the oil guide ring 331 is connected to the outside at the through hole. A sealing plate 332 fixedly connected to the switching frame 112 is rotatably provided on the left end of the inner side of the oil guide ring 331, and an annular reflection bowl 333 is fixedly installed on the right end of the inner side of the oil guide ring 331.

[0064] When the burner body 1 is required to work, if the fuel source used by the burner body 1 is fuel oil, the operator manually rotates the switching frame 112 in advance, so that the switching frame 112 drives the connecting pipe on the oil suction pipe 31 to correspond to the nozzle position of the burner body 1. The principle is the same as above, so that the oil guide ring 331 is arranged coaxially with the nozzle of the burner body 1, and then the asynchronous motor 116 is started. The principle is the same as above, which drives the oil suction pipe 31 to rotate. The oil suction pipe 31 shovels the unburned fuel droplets sprayed from the connecting pipe to the inner side surface position of the oil suction pipe 31 through the oil shoveling plate 32 on it.

[0065] It should be noted that if Figure 10 and Figure 11 As shown, a planetary gear is provided at the right end of the sealing plate 332, an external gear meshing with the inner part of the planetary gear is fixedly mounted on the left end of the inner side surface of the oil suction pipe component 31, and a central gear meshing with the outer part of the planetary gear is fixedly mounted on the left end surface of the oil guide ring component 331, so that when the oil suction pipe component 31 rotates, the oil guide ring component 331 is driven by the transmission of the external gear, the planetary gear and the central gear to rotate in the opposite direction relative to the oil suction pipe component 31.

[0066] When the oil guide ring 331 rotates, the spiral plate structure thereon pushes the air between the outer side of the oil guide ring 331 and the inner side of the oil suction pipe 31 through the opening to the inner side of the oil guide ring 331, so that a negative pressure is formed between the outer side of the oil guide ring 331 and the inner side of the oil suction pipe 31. The negative pressure shovels the oil shoveling plate 32 to the inner side of the oil suction pipe 31, and the fuel droplets are adsorbed between the outer side of the oil guide ring 331 and the inner side of the oil suction pipe 31, so that the fuel droplets collide with the rapidly rotating spiral plate structure, and the fuel droplets are further atomized through the collision.

[0067] Then, the fuel droplets after the first atomization move to the inner side of the oil guide ring 331 through the through opening. Since the sealing plate 332 closes the left end of the oil guide ring 331, the airflow drives the fuel droplets to move to the right onto the annular reflection bowl 333, so that the fuel droplets collide with the annular reflection bowl 333 for a second time and are atomized. Then, the fuel droplets after the second atomization are guided by the annular reflection bowl 333 to the corresponding position of the joint pipe to participate in combustion again.

[0068] When the present invention is in operation, it also includes the following steps: In the first step, if the fuel source used by the burner body 1 is pulverized coal, the operator manually rotates the switching frame 112 so that the joint pipe on the fixed pipe rack 21 is coaxially arranged with the nozzle of the burner body 1.

[0069] In the second step, during operation, the agglomerated unburned coal powder is sprayed onto the left side of the annular filter plate 23, and the asynchronous motor 116 is started to rotate through the annular filter plate 23 to the position of the scraper member 241, so that the scraper member 241 scrapes the coal powder on the annular filter plate 23 and drops it onto the rotating ring 22, and the rotating ring 22 synchronously collects the scraped coal powder.

[0070] In the third step, the rotating ring 22 drives all the grinding rollers 242 to rotate synchronously, so that the grinding rollers 242 crush the coal powder driven to the corresponding position by the rotating ring 22 through their outer sides, and at the same time drive the impact member 245 to impact the coal powder. The elastic force of the push spring pushes the impact member 245 to impact the coal powder. Through the coordinated action of the three methods of crushing, impacting and vibrating, the agglomerated coal powder is crushed again.

[0071] In the fourth step, the continuously rotating slewing ring 22 drives the coal powder to the position of the U-shaped frame 251. The U-shaped frame 251 scrapes the coal powder on the slewing ring 22 and drops it onto the shaking plate 252. The annular internal gear drives the shaking plate 252 to shake the coal powder until it is evenly distributed. At the same time, it drives the powder raising plate 253 to intermittently lift the coal powder that has slid down to the position of the powder raising plate 253, further increasing the dispersion of the coal powder. Then the coal powder falls to the corresponding position of the joint pipe and participates in combustion again.

[0072] In the fifth step, if the fuel source used by the burner body 1 is fuel oil, the operator manually rotates the switching frame 112 in advance so that the switching frame 112 drives the joint pipe on the oil suction pipe 31 to the corresponding nozzle position of the burner body 1, and starts the asynchronous motor 116 to drive the oil suction pipe 31 to rotate and shovel the unburned fuel droplets sprayed from the joint pipe to the inner side surface position of the oil suction pipe 31.

[0073] In the sixth step, when the oil guide ring 331 rotates, the oil shoveling plate 32 is shoveled to the inner side surface of the oil suction pipe 31, and the fuel droplets are adsorbed between the outer side of the oil guide ring 331 and the inner side of the oil suction pipe 31, so that the fuel droplets collide with the rapidly rotating spiral plate structure, thereby further atomizing the fuel droplets through collision.

[0074] In the seventh step, the fuel droplets after the first atomization move to the inner side of the oil guide ring 331 through the through opening, and move to the right to collide with the annular reflector bowl 333, so that the fuel droplets collide with the annular reflector bowl 333 for a second time and are atomized. Then, the fuel droplets after the second atomization are guided by the annular reflector bowl 333 to the corresponding position of the joint pipe position to participate in combustion again.

[0075] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention, and these changes shall still be within the scope of protection of the present invention.
