Description

Technical Field

[0001] This invention relates to the field of organic solid waste biomass incineration technology, and in particular to a melting furnace for organic solid waste incineration and its usage method. Background Technology

[0002] Biomass organic solid waste mainly refers to waste containing a large amount of organic matter from agriculture (such as straw and livestock manure), food processing (such as kitchen waste and fruit peels), and municipal solid waste. This type of waste has a complex composition and usually contains biomass organic matter such as cellulose and lignin. It needs to be treated in a harmless manner before it can be discharged. Especially for municipal solid waste, due to incomplete classification or incorrect disposal, organic solid waste may be mixed with other types of solid waste. For this type of mixed organic solid waste, incineration technology is widely used because of its high efficiency in volume reduction and energy recovery. Among them, rotary kilns have become the mainstream equipment due to their strong adaptability. Rotary kilns can completely decompose biomass organic matter through high-temperature combustion and recover heat energy at the same time.

[0003] To allow sufficient time for solid waste to burn in a rotary kiln, existing rotary kilns are typically enormous, resulting in high construction costs and making maintenance inconvenient. Furthermore, their large size necessitates significant energy consumption to maintain rotation and internal high temperatures, leading to substantial energy expenditure. Based on the above information, this application proposes a melting furnace for organic solid waste incineration and its usage method to address these issues. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the above technical background, the present invention provides a melting furnace for incinerating organic solid waste and a method for using the same.

[0005] The technical solution is as follows: a melting furnace for incinerating organic solid waste, comprising: a frame, wherein the frame is rotatably connected to uniformly arranged support wheels; a rotary furnace, disposed on the uniformly arranged support wheels; a fixed shell, fixedly connected to the frame, the fixed shell being rotatably connected to and communicating with the rotary furnace, and a discharge port being provided on the lower side of the fixed shell; a sealing plate, rotatably connected to the rotary furnace; a rotating shaft, rotatably connected between the fixed shell and the sealing plate, wherein spaced-apart baffles are fixedly connected inside the rotary furnace, and spaced-apart fixed rods are fixedly connected to the rotating shaft, wherein the baffles are annular plates with openings, the openings on adjacent baffles being staggered, and scraping plates are fixedly connected to the fixed rods, the scraping plates contacting the inner wall of the rotary furnace; and a power mechanism, disposed on the frame, for driving the rotary furnace and the rotating shaft to rotate.

[0006] As an improvement to the above solution, the scraper is a curved plate, and all the scrapers together form a "spiral plate" to directionally extrude the material to be processed in the rotary kiln.

[0007] As an improvement to the above solution, the power mechanism includes: a motor, mounted on the frame, the output shaft of the motor being fixedly connected to a transmission shaft via a coupling, the transmission shaft being rotatably connected to the frame, the transmission shaft being connected to the rotary kiln via a gear and ring drive, the transmission shaft being connected to the rotating shaft via a pulley and belt drive, and the rotation direction of the rotary kiln being opposite to the rotation direction of the rotating shaft.

[0008] As an improvement to the above solution, it also includes: spring telescopic rods arranged in a ring array, all rotatably connected to the rotating shaft, a limiting groove provided inside the rotary furnace, and a limiting ball fixedly connected to the telescopic part of the spring telescopic rod, the limiting groove being used to limit the limiting ball.

[0009] As an improvement to the above solution, the limiting groove is an annular wavy groove, which is used to cause the adjacent spring telescopic rods to deflect relative to each other, thereby pulling the object being processed.

[0010] As an improvement to the above solution, it also includes: a first stirring rod, which is arranged at intervals and is fixedly connected to the baffle plate near the limiting groove; and a second stirring rod is fixedly connected to the fixing part of the spring telescopic rod.

[0011] As an improvement to the above solution, the first stirring rod is wavy, the second stirring rod is arc-shaped, and the second stirring rod corresponds to the "recess" on the first stirring rod.

[0012] As an improvement to the above solution, the scraper plates located in the middle of the rotary kiln are all fixedly connected with levers, and the baffle plates located on the side of the rotary kiln away from the sealing plate are all fixedly connected with spaced-apart pockets. The pockets are arc-shaped plates used to spread the processed material in the rotary kiln.

[0013] As an improvement to the above solution, the curvature of the swivel plate gradually increases along the rotation direction of the rotary kiln, so as to continuously detach the processed material from the swivel plate.

[0014] A method of using a melting furnace for incinerating organic solid waste, based on the aforementioned melting furnace for incinerating organic solid waste, includes the following steps:

[0015] Step 1: The output shaft of the motor drives the transmission shaft to rotate, which in turn drives the rotary kiln and the rotating shaft to rotate. The rotary kiln and the rotating shaft then begin to rotate in opposite directions. The material to be processed is then added into the rotary kiln, and the material is incinerated in this way. During the process, the baffle plate blocks the material from being processed.

[0016] Step 2: Use the rotating scraper to continuously scrape the inner wall of the rotary kiln, turn over the scraped-off processed material, and simultaneously squeeze the processed material in a directional manner to discharge the burnt-out processed material.

[0017] Step 3: Under the limiting guidance of the limiting groove, the limiting ball drives the adjacent spring telescopic rod to deflect repeatedly, thus moving the processed items in the adjacent areas, thereby separating the processed items that are stuck together. At the same time, the relative deflection between the adjacent spring telescopic rods "tears" the stubborn processed items.

[0018] Step 4: The first and second stirring rods rotate in opposite directions to shear the materials in adjacent areas, thus breaking down hard materials. At the same time, the spring telescopic rod drives the adjacent second stirring rod to deflect together, so that the second stirring rod and the adjacent first stirring rod cooperate to squeeze the adjacent materials.

[0019] Step 5: During the rotation of the lever, the material being processed is carried away from the combustion process, making it relatively loose. At the same time, the rotating baffle carries away and releases the material at the bottom of the rotary kiln. This allows the material in the burnt-out state to spread throughout the rotary kiln, facilitating the complete combustion of any buried material. After processing is complete, the motor is turned off.

[0020] Compared to existing technologies, the present invention has at least the following beneficial effects: The present invention uses a baffle plate to block the processed material, thereby extending the residence time of the material in the rotary kiln, compensating for the reduced straight-line distance caused by the shortened length of the rotary kiln, effectively reducing the overall footprint of the device, and also reducing heat loss in the incineration system; by using the baffle plate to block solid waste, the conventional movement trajectory of the processed material is altered, increasing the diversity of its movement, improving its dispersion, and increasing the uniformity of heating, thereby improving the processing effect; by using a scraping plate to scrape and turn the processed material adhering to the inner wall of the rotary kiln, the post-processing cleaning steps are reduced, the workload of workers is lowered, and the incineration efficiency of the processed material is improved; by using a limiting groove to guide and limit the limiting ball, the spring telescopic rod deflects, thereby controlling the adjacent areas... The process involves moving the materials within the combustion zone to separate those that are stuck together, thereby increasing the surface area exposed to heat, accelerating the incineration rate, and improving the incineration effect and efficiency. The relative deflection between adjacent spring-loaded telescopic rods "tears" stubborn materials apart, preventing them from shrinking and enveloping adjacent materials during combustion, thus reducing the incineration area and efficiency. The relative movement between the first and second stirring rods compresses and shears the materials in adjacent zones, breaking down hard materials and increasing their surface area ratio, thereby improving the incineration rate. Finally, the levers and baffles tumble the materials in adjacent zones, further increasing the surface area exposed to heat and enhancing the incineration effect and degree of combustion of solid waste.

[0031] Example 1

[0032] This embodiment discloses a melting furnace for incinerating organic solid waste, used for the harmless treatment of solid waste.

[0033] like Figures 1-4As shown, it includes: a frame 1, which is welded from structural steel, and the upper side of the frame 1 is an inclined surface that gradually slopes downward from left to right. The upper part of the frame 1 is rotatably connected to evenly arranged support wheels 2; a rotary kiln 3, which is mounted on the evenly arranged support wheels 2, which support the rotary kiln 3. The length of the rotary kiln 3 is reduced by half compared to existing technologies; a fixed shell 4, which is fixedly connected to the frame 1 and rotatably connected to the rotary kiln 3. The fixed shell 4 is connected to the rotary kiln 3, and has a discharge port 401 on its lower side. The upper right side of the fixed shell 4 is fixedly connected to and connected to an exhaust pipe 103, which is connected to external waste gas treatment equipment; and a sealing plate 5, which rotates... Connected to the rotary kiln 3, the upper and lower parts of the sealing plate 5 are respectively fixedly connected to the feed pipe 101 and the burner 102. The feed pipe 101 is connected to the external solid waste conveying equipment, and the burner 102 is connected to the external (natural gas) storage equipment. The rotating shaft 6 is rotatably connected between the fixed shell 4 and the sealing plate 5. The central axis of the rotary kiln 3 is parallel to the upper side of the frame 1. The central axis of the rotary kiln 3, the central axis of the fixed shell 4, the central axis of the sealing plate 5, and the central axis of the rotating shaft 6 coincide. The rotary kiln 3 is fixedly connected with spaced-apart baffle plates 7, and the rotating shaft 6 is fixedly connected with spaced-apart fixed rods 8. The baffle plates 7 are used to block the solid waste in the rotary kiln 3, thereby extending the solid waste's lifespan. During incineration, the baffle plate 7 is an annular plate (the baffle plate 7 can also be inclined to turn over solid waste; the specific arrangement can be set according to the actual situation), and it is provided with openings. The openings on adjacent baffle plates 7 are staggered. All baffle plates 7 are divided into three parts, namely the left, middle and right parts (within the rotary kiln 3). The fixing rods 8 are distributed in a spiral shape, and the fixing rods 8 are fixedly connected to scraper plates 9. The scraper plates 9 contact the inner wall of the rotary kiln 3 and are used to remove solid waste adhering to the inner wall of the rotary kiln 3. The scraper plates 9 are curved plates, and all scraper plates 9 together form a "spiral plate" to directionally squeeze the processed material in the rotary kiln 3; the power mechanism is set in the frame 1. The upper part is used to drive the rotary kiln 3 and the rotating shaft 6 to rotate respectively. The power mechanism includes: a motor 1001, which is installed on the frame 1. The output shaft of the motor 1001 is connected to the transmission shaft 1002 by a coupling after the torque is increased by the reducer. The transmission shaft 1002 is rotatably connected to the frame 1. The transmission shaft 1002 is connected to the rotary kiln 3 by a gear and ring drive. The transmission shaft 1002 is connected to the rotating shaft 6 by a pulley and belt drive. The transmission ratio between the transmission shaft 1002 and the rotary kiln 3 is greater than the transmission ratio between the transmission shaft 1002 and the rotating shaft 6, so as to make the rotary kiln 3 and the rotating shaft 6 move relative to each other. The rotation direction of the rotary kiln 3 is opposite to the rotation direction of the rotating shaft 6.

[0034] The working process of a melting furnace for incinerating organic solid waste in this embodiment is as follows:

[0035] Preparations before processing:

[0036] The staff connected the feed pipe 101 to the external solid waste conveying equipment, the burner 102 to the external (natural gas) storage equipment, and the exhaust pipe 103 to the external waste gas treatment equipment. The solid waste conveying equipment, the storage equipment, and the waste gas treatment equipment are all existing technologies, and their respective working principles will not be elaborated in detail.

[0037] Processing begins:

[0038] First, the output shaft of motor 1001 is reduced in speed and increased in torque by a reducer, and then the power is transmitted to drive shaft 1002, which begins to rotate clockwise (e.g., ...). Figure 2 Taking the left-view direction as an example), the drive shaft 1002 drives the rotary kiln 3 to rotate counterclockwise through the gear ring. The rotary kiln 3 drives the baffle plate 7 to rotate counterclockwise together. The drive shaft 1002 transmits power to the rotating shaft 6 through the pulley belt. The rotating shaft 6 starts to rotate clockwise. The rotating shaft 6 drives the fixed rod 8 to rotate clockwise together. The fixed rod 8 drives the adjacent scraper plate 9 to rotate clockwise together.

[0039] Secondly, the staff adds fuel to the burner 102 through the external (natural gas) storage equipment, and then the burner 102 generates a flame to heat the rotary kiln 3. Then, the external solid waste conveying equipment continuously conveys solid waste into the feed pipe 101. The solid waste is then sent into the rotary kiln 3, where it begins to burn and decompose gradually under the action of high temperature.

[0040] During the counterclockwise rotation of rotary kiln 3, solid waste tends to move to the right under its own gravity. However, when the solid waste moves to the right and comes into contact with the adjacent baffle plate 7, it is blocked until the baffle plate 7 rotates counterclockwise until its upper opening is on the lower side, at which point the solid waste can pass through again. (During the solid waste moves from left to right in rotary kiln 3, its degree of combustion gradually increases, which can be divided into three states: initial combustion, combustion, and burnout.) This prolongs the time that the solid waste is processed in rotary kiln 3, thereby compensating for the reduced straight-line distance caused by the shortened length of rotary kiln 3, effectively reducing the overall footprint of the device, making it easier to operate, reducing heat loss in the incineration system, and lowering energy consumption during device operation. At the same time, by using the baffle plate 7 to block the solid waste, the normal movement trajectory of the solid waste is changed (the baffle plate 7 also guides the solid waste in adjacent areas), increasing the diversity of solid waste movement, improving the dispersion of solid waste, increasing the uniformity of heating of solid waste, and thus improving the treatment effect of solid waste.

[0041] As the scraper plate 9 rotates clockwise, it continuously scrapes and turns over the solid waste adhering to the inner wall of the rotary kiln 3, thereby increasing the heating area of ​​the stubborn solid waste and improving the incineration effect. At the same time, the scraper plate 9 also squeezes the solid waste to the right, thus reducing the number of cleaning steps for the staff, reducing the workload of the staff and improving the incineration efficiency of the solid waste. As the rotary kiln 3 (rotating shaft 6) continues to rotate counterclockwise (clockwise), the solid waste gradually moves to the right until the solid waste is discharged from the discharge port 401 in the form of ash after the solid waste is incinerated. The exhaust gas generated during the incineration process is discharged through the exhaust pipe 103.

[0042] Example 2

[0043] This embodiment discloses a melting furnace for incinerating organic solid waste. Based on Embodiment 1, it also has the function of pre-dispersing solid waste.

[0044] like Figure 4 As shown, it also includes: spring telescopic rods 1101, arranged in a ring array, all rotatably connected to the rotating shaft 6. Each spring telescopic rod 1101 consists of a telescopic part, a fixed part, and a spring between them. The fixed part on the spring telescopic rod 1101 is rotatably connected to the rotating shaft 6. A limiting groove 1102 is provided inside the rotary kiln 3. The telescopic part of the spring telescopic rod 1101 is fixedly connected to a limiting ball 1103. The limiting groove 1102 is used to limit the limiting ball 1103. The limiting groove 1102 is an annular wavy groove, that is, the projection of the limiting groove 1102 on the inner wall of the rotary kiln 3 is wavy. This wavy shape is parallel to the central axis of the rotary kiln 3, which is used to cause the adjacent spring telescopic rods 1101 to deflect relative to each other, thereby pulling the processed material.

[0045] The above setup enables the following: during the clockwise rotation of the rotating shaft 6, the rotating shaft 6 drives the spring telescopic rod 1101 to rotate clockwise as well. The spring telescopic rod 1101 then drives the adjacent limiting ball 1103 to rotate clockwise as well. The limiting ball 1103 then begins to move within the limiting groove 1102. For ease of description, it is now referred to as... Figure 4 Taking the movement of the lower spring telescopic rod 1101 and the limiting ball 1103 as an example, the limiting ball 1103 begins to move to the left under the guidance and limiting action of the limiting groove 1102. The limiting ball 1103 drives the telescopic part of the spring telescopic rod 1101 to move to the left together, and the entire spring telescopic rod 1101 begins to deflect counterclockwise (e.g., Figure 4Taking the forward direction as an example, the spring telescopic rod 1101 rotates relative to the rotating shaft 6, and at the same time, the spring telescopic rod 1101 extends. As the rotating shaft 6 continues to rotate clockwise, the spring telescopic rod 1101 repeatedly deflects left and right, thereby moving the solid waste in the adjacent area, thus separating the solid waste that is stuck together, thereby increasing the heating area of ​​the solid waste, accelerating the incineration rate of the solid waste, and thus improving the effect and efficiency of solid waste incineration. At the same time, the relative deflection between two adjacent spring telescopic rods 1101 causes stubborn solid waste (such as plastic bags) to "tear", preventing stubborn solid waste from shrinking and wrapping around adjacent solid waste during combustion, reducing the incineration area, and thus reducing the incineration efficiency of solid waste.

[0046] Example 3

[0047] This embodiment discloses a melting furnace for incinerating organic solid waste, which further enhances the effect of solid waste dispersion based on Embodiment 2.

[0048] like Figure 4 As shown, it also includes: a first stirring rod 12, which is arranged at intervals and is fixedly connected to the baffle plate 7 near the limiting groove 1102; a second stirring rod 13 is fixedly connected to the fixing part of the spring telescopic rod 1101; the first stirring rod 12 is wavy and the second stirring rod 13 is arc-shaped, and the second stirring rod 13 corresponds to the "recess" on the first stirring rod 12.

[0049] The above setup enables the leftmost baffle plate 7 to rotate counterclockwise, causing the first stirring rod 12 to rotate counterclockwise as well. Simultaneously, the spring telescopic rod 1101 rotates clockwise with the rotating shaft 6, causing the adjacent second stirring rod 13 to rotate clockwise as well. The first and second stirring rods 12 and 13 further agitate the solid waste, increasing its incineration area and thus improving incineration efficiency. Simultaneously, the relatively rotating first and second stirring rods 12 and 13 "shear" the solid waste in adjacent areas, thus breaking up hard solid waste and increasing its surface area ratio, thereby improving the incineration rate. Furthermore, the spring telescopic rod 1101 causes the adjacent second stirring rod 13 to deflect left and right, allowing the second stirring rod 13 to work in conjunction with the adjacent first stirring rod 12 to compress the adjacent solid waste, further enhancing the crushing effect.

[0050] Example 4

[0051] This embodiment discloses a melting furnace for incinerating organic solid waste. Based on Embodiment 3, it also has the function of scattering solid waste to further increase the degree of incineration of solid waste.

[0052] like Figures 5-7As shown, the scraper plates 9 located in the middle of the rotary kiln 3 are all fixedly connected with levers 14, and the baffle plates 7 located on the right side of the rotary kiln 3 are all fixedly connected with spaced-apart pocket plates 15. The pocket plates 15 are arc-shaped plates, and the "openings" on the pocket plates 15 face the side closest to the rotating shaft 6, which is used to spread the processed material in the rotary kiln 3. The curvature of the pocket plates 15 gradually increases along the rotation direction of the rotary kiln 3, which is used to make the processed material continuously detach from the pocket plates 15, that is, to prolong the residence time of the processed material on the pocket plates 15.

[0053] The above settings enable the scraper plate 9 to rotate clockwise, causing the lever 14 to rotate clockwise as well. When the lever 14 moves to the lower part of the rotary kiln 3, it enters the solid waste in combustion. As the lever 14 continues to rotate clockwise, it moves the solid waste in the adjacent area, thus making the solid waste in the combustion process relatively loose, increasing the heat-receiving area of ​​the solid waste, and thereby improving the incineration effect of the solid waste.

[0054] As the baffle plate 7 rotates counterclockwise, it drives the sump plate 15 to rotate counterclockwise as well. The sump plate 15 transfers the solid waste in the adjacent area (the solid waste in this area is already in the burnout stage). Then, as the sump plate 15 rotates counterclockwise, it continuously releases the sump plate, causing the ash-like solid waste to spread in the right side of the rotary kiln 3, thereby burning the solid waste buried inside the ash and that has not yet been burned out, thus increasing the degree of incineration of the solid waste.

[0055] Example 5

[0056] like Figures 1-7 As shown, this embodiment discloses a method for using a melting furnace for incinerating organic solid waste. Based on the above-mentioned melting furnace for incinerating organic solid waste, the method includes the following steps:

[0057] Step 1: The output shaft of motor 1001 drives the transmission shaft 1002 to rotate, and the transmission shaft 1002 drives the rotary furnace 3 and the rotating shaft 6 to rotate. The rotary furnace 3 and the rotating shaft 6 start to rotate in opposite directions. Then, the material to be processed is added into the rotary furnace 3, and the material is incinerated in this way. During the process, the baffle plate 7 blocks the material to be processed.

[0058] Step 2: Use the rotating scraper 9 to continuously scrape the inner wall of the rotary kiln 3, turn over the scraped-off processed material, and at the same time, directionally squeeze the processed material to discharge the burnt-out processed material.

[0059] Step 3: Under the limiting guidance of the limiting groove 1102, the limiting ball 1103 drives the adjacent spring telescopic rod 1101 to deflect repeatedly, thus moving the processed items in the adjacent area, thereby separating the processed items that are stuck together. At the same time, the relative deflection between the adjacent spring telescopic rods 1101 is used to "tear" the stubborn processed items.

[0060] Step 4: The first stirring rod 12 and the second stirring rod 13 rotate in opposite directions to shear the processed materials in the adjacent areas, thus breaking down the hard processed materials. At the same time, the spring telescopic rod 1101 drives the adjacent second stirring rod 13 to deflect together, so that the second stirring rod 13 cooperates with the adjacent first stirring rod 12 to squeeze the adjacent processed materials.

[0061] Step 5: During the rotation of lever 14, the processed material in the combustion process is carried away, making the processed material in the combustion state relatively loose. At the same time, the rotating baffle 15 is used to carry away and release the processed material at the bottom of the rotary kiln 3. In this way, the processed material in the burnt-out state is spread throughout the rotary kiln 3, which facilitates the complete combustion of the buried processed material. After the processing is completed, the motor 1001 is turned off.

[0062] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0063] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.

A method of using the melting furnace for incinerating organic solid waste according to claim 3, characterized by, The specific steps are as follows: Step one: the output shaft of the motor (1001) drives the transmission shaft (1002) to rotate, the transmission shaft (1002) drives the rotary furnace (3) and the rotating shaft (6) to rotate, the rotary furnace (3) and the rotating shaft (6) start to rotate in opposite directions, then the processing objects are added in the rotary furnace (3), so that the processing objects are incinerated, and the blocking plate (7) blocks the processing objects in the process; Step two: the rotating scraping plate (9) continuously scrapes the inner wall of the rotary furnace (3), turns over the scraped processing objects, and directionally extrudes the processing objects to discharge the burned-out processing objects; Step three: the limiting ball (1103) drives the adjacent spring telescopic rod (1101) to repeatedly deflect under the limiting guidance of the limiting groove (1102), so that the processing objects in the adjacent area are stirred, so that the processing objects are separated, and the stubborn processing objects are "torn" by the relative deflection between the adjacent spring telescopic rods (1101); Step four: the first stirring rod (12) and the second stirring rod (13) are reversely rotated to shear the processing objects in the adjacent area, so that the processing objects with hard texture are broken, and the second stirring rod (13) is driven by the spring telescopic rod (1101) to deflect together with the adjacent second stirring rod (13), so that the second stirring rod (13) cooperates with the adjacent first stirring rod (12) to extrude the adjacent processing objects; Step five: the processing objects in the combustion process are taken away by the rotating stirring rod (14), so that the processing objects in the combustion state are relatively loose, and the processing objects at the bottom of the rotary furnace (3) are taken away and released by the rotating pocket plate (15), so that the processing objects in the burned-out state diffuse in the rotary furnace (3), so that the processing objects are fully burned, and the motor (1001) is closed after the processing is completed.
