Technical Field

[0001] The present invention relates to the technical field of burners, and specifically to a high-efficiency energy-saving burner for a suspension kiln and its energy-saving combustion method. Background Technique

[0002] A suspension kiln is a device for processing various ores. It is a large cylindrical device, usually made of reinforced concrete or other high-temperature materials, and can convert raw materials into clinker at high temperatures. In a suspension kiln, raw materials enter from above, and through the rotation of the kiln cylinder and chemical reactions at high temperatures, clinker is finally produced. The burner of the suspension kiln is usually vertically installed with it, which is completely different from the common rotary kiln. A burner is a device that sprays fuel and air in a certain way for mixed combustion. For different kiln bodies, different burners are used;

[0003] At present, the existing burners have a low energy utilization rate during use, resulting in serious energy waste. Moreover, the flames sprayed by the existing burners are long and have a small diameter, and cannot be adjusted, so it is very easy to burn out the kiln wall, and the flame utilization rate is also low. In addition, it is very inconvenient for users during installation and later use. Due to its heavy weight, it is usually moved and installed by a traveling crane, so it has certain requirements for the installation site and cannot meet various sites. As a result, when users install and maintain it, it will take a lot of time and reduce the work efficiency of users. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-efficiency energy-saving burner for a suspension kiln and its energy-saving combustion method to solve the problems raised in the above background technique, that is, the existing burners have a low energy utilization rate during use, resulting in serious energy waste, and the flames sprayed by the existing burners are long and have a small diameter, and cannot be adjusted, so it is very easy to burn out the kiln wall, and the flame utilization rate is also low. In addition, it is very inconvenient for users during installation and later use. Due to its heavy weight, it is usually moved and installed by a traveling crane, so it has certain requirements for the installation site and cannot meet various sites. As a result, when users install and maintain it, it will take a lot of time and reduce the work efficiency of users. Through this solution, it can not only facilitate the installation and support work of users, but also provide great convenience for subsequent maintenance, greatly shortening the disassembly and assembly work of users during maintenance, thereby improving the work efficiency of users, ensuring the normal production of products.

[0013] The energy-saving combustion method of the device:

[0014] Step 1: Ignition. The user passes gas into the ignition tube and the fuel tube, and passes compressed air into the main air inlet pipe. The air can enter the inside of the steady flow box through the main air inlet pipe. The user opens a group of valves. At this time, the air enters between the third swirl tube and the central tube through the third air inlet pipe, the air is discharged through the air outlet, and then discharged through the ignition tube, and ignition can be carried out through the igniter.

[0015] Step 2: Combustion support. The air discharged through the air outlet is neutral air, which can help the igniter to ignite the gas discharged from the ignition tube.

[0016] Step 3: Combustion. The gas entering the fuel pipe is discharged between the first swirl pipe and the second swirl pipe. A swirl can be formed through the second swirl plate. After the user opens all the valves, air enters between the installation outer pipe and the first swirl pipe through the first air inlet pipe, and a swirl can be formed through the first swirl plate. Air enters between the second swirl pipe and the third swirl pipe through the second air inlet pipe, and a swirl can be formed through the third swirl plate. At this time, three swirl winds are formed from the outside to the inside, and the first, second, and third swirl winds are formed through the first swirl plate, the second swirl plate, and the third swirl plate respectively. The first and third swirl winds are air, and the second swirl wind is gas. The main function of the first swirl wind is to pull the gas outwards, so that the gas is fully mixed with the air in the outside environment, improving the combustion efficiency. The second swirl wind is gas, which is mainly used to eject the gas along the radial direction, increasing the flame diameter and fully mixing the outside air at the same time, increasing the flame area, and further improving the combustion efficiency. The normal amount of the third swirl wind is less than that of the first swirl wind. Its main function is to adjust the flame diameter. If the flame is too thin and the flame combustion area is small at this time, the third swirl wind is increased, and vice versa. When the gas discharged between the first swirl pipe and the second swirl pipe is ignited by the scattered flame of the ignition pipe, the neutral wind discharged through the air outlet can also improve the flame stability;

[0017] Step 4: Adjustment. The user can control the diameter and length of the flame through the valve.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] When the user installs this device, the user first uses a crane to lift the upper part of this device, and then moves the support and maintenance box to the bottom ends of the first swirl tube and the second swirl tube. Push the rotating rod so that the slider slides to one side of the first support rod. After the second gear meshes with a set of first gears, then place the lock plate into the interior of the lock groove. At this time, the locking work is completed. The user rotates the rotating rod, and through the second gear and the first gear, the threaded rod can be rotated. Through the threaded rod, the first support rod moves upward. When the bottom end of the first support rod fits with the bottom end of the first swirl tube, the user then takes out the lock plate, moves the rotating rod to the other end, so that the second gear meshes with another set of first gears, and by rotating the rotating rod, another set of first support rods are moved upward until their top ends fit with the bottom end of the second swirl tube. The user connects the two sets of first support rods to the first swirl tube and the second swirl tube respectively through bolts. Then the user pulls the buckle plate, and the buckle plate rotates and compresses the second torsion spring. One end of the buckle plate moves downward, and at the same time, it pushes the top end of the transfer plate to rotate, so that one end of the transfer plate drives the lock to rotate, so that one end of the lock no longer latches the card slot. At this time, the user can pull out the movable box, and at the same time drive the guide block to slide inside the guide groove, thus completing the positioning and guiding work. Then the user pulls the second support rod upward. After the inclined surface of the fixed groove abuts against the inclined surface of the fixed block, the top end of the self-locking block moves away from one end of the second support rod, and at the same time compresses the second spring. When the user pulls the second support rod upward, a knocking sound will be continuously heard. When the user pulls the second support rod to an appropriate height, at this time, through the second spring, the self-locking block, the fixed block and the fixed groove, the second support rod can be locked to prevent the second support rod from automatically falling, so that the second support rod can support the installation outer pipe. When the user moves this device to the position of the installation pipeline, the user can fine-tune the heights of the installation outer pipe, the first swirl tube, the second swirl tube and the third swirl tube through the rotating rod and the second gear to make their heights consistent with the height of the installation pipeline, thus facilitating the installation and connection work of the user. Then the user pushes the support and maintenance box, inserts the installation outer pipe into the interior of the installation pipeline, and then connects the installation outer pipe and the installation pipeline through bolts. At this time, through the support and maintenance box, the movable box, the first support rod and the second support rod, the installation outer pipe, the first swirl tube, the second swirl tube and the third swirl tube can be supported. At this time, the user has completed the installation of this device. The user introduces gas into the ignition tube and the fuel tube, and introduces compressed air into the main air inlet pipe. The air can enter the interior of the steady flow box through the main air inlet pipe. The user opens a set of valves. At this time, the air enters between the third swirl tube and the central tube through the third air inlet pipe, and the air is discharged through the air outlet, and then discharged through the ignition tube. Ignition can be carried out through the igniter. The air discharged through the air outlet is neutral air, which can help the igniter ignite the gas discharged from the ignition tube and has an auxiliary combustion effect. The gas entering the fuel tube is discharged between the first swirl tube and the second swirl tube, and a swirl can be formed through the second swirl plate. After the user opens all the valves,Air enters between the installation outer tube and the first cyclone tube through the first air inlet pipe. A swirl can be formed through the first swirl plate. Air enters between the second cyclone tube and the third cyclone tube through the second air inlet pipe. A swirl can be formed through the third swirl plate. At this time, three swirl winds are formed from outside to inside. Respectively, the first, second, and third swirl winds are formed through the first swirl plate, the second swirl plate, and the third swirl plate. The first and third swirl winds are air, and the second swirl wind is gas. The main function of the first swirl wind is to pull the gas outwards, enabling the gas to be fully mixed with the air in the external environment and improving the combustion efficiency. The second swirl wind is gas, which mainly sprays the gas along the radial direction, increasing the flame diameter while fully mixing with the outside air, enlarging the flame area, and further improving the combustion efficiency. The normal amount of the third swirl wind is less than that of the first swirl wind. Its main function is to adjust the diameter of the flame. If the flame is too thin and the combustion area of the flame is small at this time, then the third swirl wind is increased; otherwise, the third swirl wind is decreased. When the gas ejected between the first cyclone tube and the second cyclone tube is ignited by the scattered flame of the ignition tube, the neutral wind discharged through the air outlet can also improve the stability of the flame, thus making the combustion work more convenient. The user can control the diameter and length of the flame through the valve, preventing the flame from burning the inner lining of the kiln wall. At the same time, the internal pressure of the steady flow box can be monitored through the pressure sensor. When the internal pressure of the steady flow box is too low, the output end of the electric push rod will lift one end of the cover plate. At this time, the air inside the main air inlet pipe enters the inside of the steady flow box, thus ensuring the stability of the internal pressure of the steady flow box, providing a stable pressure for the subsequent air intake work, and avoiding the situation of uneven pressure. This device can not only facilitate the installation and support work of the user, but also provide great convenience for subsequent maintenance. It can greatly shorten the disassembly and assembly work of the user during maintenance, thereby improving the work efficiency of the user, ensuring the normal production of products. At the same time, the user can adjust the diameter and length of the flame according to the usage requirements, thereby improving the utilization rate of gas, reducing energy consumption, and thus reducing the usage cost.

Fixedly connected to the middle of the transfer plates 54 are lock catches 57, and one ends of the lock catches 57 are located inside the card slots 49. When the user installs this device, the user first uses a crane to lift the upper half of this device, and then moves the support and maintenance box 27 to the bottom ends of the first swirl tube 4 and the second swirl tube 5. Push the rotating rod 34, the rotating rod 34 drives the slider 33 to slide towards one side of the first support rod 28, and at the same time the rotating rod 34 drives the slider 33 to slide inside the sliding groove 32. When the second gear 35 meshes with a set of first gears 31, then put the lock plate 36 into the lock slot 41, and at this time the locking work is completed. The user rotates the rotating rod 34, the rotating rod 34 drives the second gear 35 to rotate, the second gear 35 drives the first gear 31 to rotate, and the rotating first gear 31 can make the threaded rod 30 rotate. Through the threaded rod 30, the first support rod 28 moves upward. When the bottom end of the first support rod 28 is in contact with the bottom end of the first swirl tube 4, the user then takes out the lock plate 36, moves the rotating rod 34 to the other end, makes the second gear 35 mesh with another set of first gears 31, and then places the lock plate 36 in the other set of lock slots 41, and then makes the other set of first support rods 28 move upward by rotating the rotating rod 34 again until its top end is in contact with the bottom end of the second swirl tube 5. The user connects the two sets of first support rods 28 to the first swirl tube 4 and the second swirl tube 5 respectively through bolts. Then the user pulls the buckle plate 51, the buckle plate 51 rotates and compresses the second torsion spring 56, one end of the buckle plate 51 moves downward, and at the same time pushes the top of the transfer plate 54 to rotate, so that one end of the transfer plate 54 drives the lock catch 57 to rotate, and at the same time the second torsion spring 56 is compressed. When one end of the lock catch 57 no longer latches the card slot 49, at this time the user can pull out the movable box 37, and at the same time drive the guide block 40 to slide inside the guide groove 39, thus completing the positioning and guiding work. After the user releases the buckle plate 51, the buckle plate 51 and the transfer plate 54 are reset under the action of the first torsion spring 53 and the second torsion spring 56.When the user pulls the second support rod 38 upward, after the inclined surface of the fixing groove 45 abuts against the inclined surface of the fixing block 46, the top end of the self-locking block 43 moves away from one end of the second support rod 38, and at the same time, the second spring 44 is compressed. When the next fixing block 46 moves to the position of the fixing groove 45, it is reset under the action of the self-elastic force of the second spring 44. At this time, the user will continuously hear knocking sounds when pulling the second support rod 38 upward. When the user pulls the second support rod 38 to an appropriate height, at this time, the second support rod 38 can be locked by the second spring 44, the self-locking block 43, the fixing block 46 and the fixing groove 45, preventing the second support rod 38 from automatically falling.

Then the user pushes the support and maintenance box 27, inserts the installation outer tube 3 into the interior of the installation pipeline 2, and then connects the installation outer tube 3 and the installation pipeline 2 through bolts. At this time, the installation outer tube 3, the first swirl tube 4, the second swirl tube 5 and the third swirl tube 6 can be supported by the support and maintenance box 27, the movable box 37, the first support rod 28 and the second support rod 38. At this time, the user has completed the installation of the device. When the user needs to perform maintenance, the user removes the bolts between the installation outer tube 3 and the installation pipeline 2, and can move the installation outer tube 3, the first swirl tube 4, the second swirl tube 5 and the third swirl tube 6 through the support and maintenance box 27 and the movable box 37 until they are moved out of the installation pipeline 2. At this time, the user can perform maintenance work, which is convenient for the user to disassemble, install and maintain, and can also provide support;

[0036] The energy-saving combustion method of this device:

[0037] Step 1: Ignition. The user passes gas into the ignition pipe 12 and the fuel pipe 14, and passes compressed air into the total air inlet pipe 23. The air can enter the inside of the steady flow box 19 through the total air inlet pipe 23. The user opens a group of valves 18. At this time, the air enters between the third swirl pipe 6 and the central pipe 10 through the third air inlet pipe 17, is discharged through the air outlet 11, and then is discharged through the ignition pipe 12, and ignition can be carried out through the igniter 13;

[0038] Step 2: Combustion assistance. The air discharged through the air outlet 11 is neutral air, which can help the igniter 13 to ignite the gas discharged from the ignition pipe 12;

[0039] Step 3: Combustion. The gas entering the fuel pipe 14 is discharged between the first swirler 4 and the second swirler 5. A swirl can be formed through the second swirler plate 8. After the user opens all the valves 18, air enters between the installation outer pipe 3 and the first swirler 4 through the first air inlet pipe 15, and a swirl can be formed through the first swirler plate 7. Air enters between the second swirler 5 and the third swirler 6 through the second air inlet pipe 16, and a swirl can be formed through the third swirler plate 9. At this time, three swirl winds are formed from outside to inside, and the first, second, and third swirl winds are formed through the first swirler plate 7, the second swirler plate 8, and the third swirler plate 9 respectively. The first and third swirl winds are air, and the second swirl wind is gas. The main function of the first swirl wind is to pull the gas outwards, enabling the gas to be fully mixed with the air in the external environment and improving the combustion efficiency. The second swirl wind is gas, which mainly sprays the gas in the radial direction, increasing the flame diameter and fully mixing with the external air, increasing the flame area, and further improving the combustion efficiency. The normal amount of the third swirl wind is less than that of the first swirl wind. Its main function is to adjust the flame diameter. If the flame is too thin and the combustion area of the flame is small at this time, the third swirl wind is increased; otherwise, the third swirl wind is decreased. When the gas discharged between the first swirler 4 and the second swirler 5 is ignited by the dispersed flame of the ignition pipe 12, the neutral wind discharged through the air outlet 11 can also improve the flame stability;

[0040] Step 4: Adjustment. The user can control the diameter and length of the flame through the valve 18.

[0041] Working principle: When the user installs this device, the user first hoists the upper part of this device with a crane, and then moves the support and maintenance box 27 to the bottom ends of the first cyclone tube 4 and the second cyclone tube 5. Push the rotating rod 34, and the rotating rod 34 drives the slider 33 to slide towards one side of the first support rod 28. At the same time, the rotating rod 34 drives the slider 33 to slide inside the chute 32. When the second gear 35 meshes with a set of first gears 31, then put the lock plate 36 into the inside of the lock groove 41. At this time, the locking work is completed. The user rotates the rotating rod 34, and the rotating rod 34 drives the second gear 35 to rotate. The second gear 35 drives the first gear 31 to rotate. Through the rotating first gear 31, the threaded rod 30 can be rotated. Through the threaded rod 30, the first support rod 28 moves upward. When the bottom end of the first support rod 28 fits with the bottom end of the first cyclone tube 4, the user then takes out the lock plate 36, moves the rotating rod 34 to the other end, makes the second gear 35 mesh with another set of first gears 31, and then places the lock plate 36 inside another set of lock grooves 41. Then, by rotating the rotating rod 34 again, another set of first support rods 28 are moved upward until their top ends fit with the bottom end of the second cyclone tube 5. The user connects the two sets of first support rods 28 to the first cyclone tube 4 and the second cyclone tube 5 respectively through bolts. Then the user pulls the buckle plate 51, and the buckle plate 51 rotates and compresses the second torsion spring 56. One end of the buckle plate 51 moves downward, and at the same time, it pushes the top end of the transfer plate 54 to rotate, so that one end of the transfer plate 54 drives the lock catch 57 to rotate, and at the same time, the second torsion spring 56 is compressed. When one end of the lock catch 57 no longer latches the card slot 49, at this time the user can pull out the movable box 37, and at the same time drive the guide block 40 to slide inside the guide groove 39, thus completing the positioning and guiding work. After the user releases the buckle plate 51, the buckle plate 51 and the transfer plate 54 are reset under the action of the first torsion spring 53 and the second torsion spring 56. The user pulls the second support rod 38, so that the second support rod 38 moves upward. After the inclined surface of the fixed groove 45 abuts against the inclined surface of the fixed block 46, the top end of the self-locking block 43 moves towards the end away from the second support rod 38, and at the same time compresses the second spring 44. When the next fixed block 46 moves to the position of the fixed groove 45, at this time it is reset under the action of the self-returning force of the second spring 44. At this time, the user will continuously hear a knocking sound when pulling up the second support rod 38. When the user pulls the second support rod 38 to an appropriate height, at this time, through the second spring 44, the self-locking block 43, the fixed block 46 and the fixed groove 45, the second support rod 38 can be locked to prevent the second support rod 38 from falling automatically. Thus, the second support rod 38 can support the installation outer tube 3. When the user moves this device to the position of the installation pipeline 2, the user can fine-tune the heights of the installation outer tube 3, the first cyclone tube 4, the second cyclone tube 5 and the third cyclone tube 6 through the rotating rod 34 and the second gear 35 to make their heights consistent with the height of the installation pipeline 2, thus facilitating the installation and connection work of the user.Then the user pushes the support and maintenance box 27, inserts the installation outer pipe 3 into the interior of the installation pipe 2, and then connects the installation outer pipe 3 and the installation pipe 2 with bolts. At this time, the installation outer pipe 3, the first swirl pipe 4, the second swirl pipe 5, and the third swirl pipe 6 can be supported by the support and maintenance box 27, the movable box 37, the first support rod 28, and the second support rod 38. At this time, the user has completed the installation of the device. The user passes gas into the ignition pipe 12 and the fuel pipe 14, and passes compressed air into the main air inlet pipe 23. The air can enter the interior of the flow stabilization box 19 through the main air inlet pipe 23. The user opens a set of valves 18. At this time, the air enters between the third swirl pipe 6 and the central pipe 10 through the third air inlet pipe 17, and the air is discharged through the air outlet 11, and then discharged through the ignition pipe 12. Ignition can be carried out through the igniter 13. The air discharged through the air outlet 11 is neutral air, which can help the igniter 13 ignite the gas discharged from the ignition pipe 12 and has an auxiliary combustion effect. The gas entering the fuel pipe 14 is discharged between the first swirl pipe 4 and the second swirl pipe 5, and a swirl can be formed through the second swirl plate 8. After the user opens all the valves 18, the air enters between the installation outer pipe 3 and the first swirl pipe 4 through the first air inlet pipe 15, and a swirl can be formed through the first swirl plate 7. The air enters between the second swirl pipe 5 and the third swirl pipe 6 through the second air inlet pipe 16, and a swirl can be formed through the third swirl plate 9. At this time, three swirl winds are formed from the outside to the inside, and the first, second, and third swirl winds are formed through the first swirl plate 7, the second swirl plate 8, and the third swirl plate 9 respectively. The first and third swirl winds are air, and the second swirl wind is gas. The main function of the first swirl wind is to pull the gas outward, so that the gas is fully mixed with the air in the outside environment, improving the combustion efficiency. The second swirl wind is gas, which is mainly used to spray the gas along the radial direction, increasing the flame diameter and fully mixing the outside air at the same time, increasing the flame area, and further improving the combustion efficiency. The normal amount of the third swirl wind is less than that of the first swirl wind. Its main function is to adjust the diameter of the flame. If the flame is too thin and the flame combustion area is small at this time, then the third swirl wind is increased, and vice versa. When the gas ejected between the first swirl pipe 4 and the second swirl pipe 5 is ignited by the scattered flame of the ignition pipe 12, the neutral air discharged through the air outlet 11 can also improve the stability of the flame, making the combustion work more convenient. The user can control the diameter and length of the flame through the valves 18 to prevent the flame from burning the inner wall of the kiln lining 1. At the same time, the pressure inside the flow stabilization box 19 can be monitored through the pressure sensor 21. When the pressure inside the flow stabilization box 19 is too low, the output end of the electric push rod 26 will lift one end of the cover plate 24. At this time, the air inside the main air inlet pipe 23 enters the interior of the flow stabilization box 19, thus ensuring the stability of the pressure inside the flow stabilization box 19, providing a stable pressure for the subsequent air intake work, and avoiding the situation of uneven pressure. This device can not only facilitate the installation and support work of the user, but also provide great convenience for subsequent maintenance.It can greatly shorten the disassembly and assembly work of users during maintenance, thereby improving the work efficiency of users, ensuring the normal production of products. At the same time, users can adjust the diameter and length of the flame according to usage requirements, thereby improving the utilization rate of gas, reducing energy consumption, and thus reducing the usage cost.

The second swirl wind is gas, which is mainly to spray the gas along the radial direction, increasing the flame diameter and fully mixing the outside air at the same time, increasing the flame area, and further improving the combustion efficiency. The normal amount of the third swirl wind is less than that of the first swirl wind. Its main function is to adjust the diameter of the flame. If the flame is too thin and the combustion area of the flame is small at this time, then the third swirl wind is increased. Otherwise, the third swirl wind is decreased. When the gas ejected between the first swirl tube and the second swirl tube is ignited by the scattered flame of the ignition tube, the neutral air discharged through the air outlet can also improve the stability of the flame. Step 4: Adjustment. The user can control the diameter and length of the flame through the valve.
