Abstract
Description
Technical Field
[0001] This invention relates to the field of waste incineration power generation technology, and more specifically, to a municipal solid waste incineration device for power generation. Background Technology
[0002] Garbage contains a large amount of combustible organic matter with a certain calorific value, and can generate a certain amount of heat after incineration. Generally speaking, the heat generated by burning 3 tons of garbage is equivalent to the heat generated by burning 1 ton of medium-calorific-value coal. Therefore, the garbage of a city is like a low-grade open-pit coal mine, which can be developed in a long-term cycle.
[0003] In real life, garbage comes in various sizes. When larger pieces of garbage enter a large incinerator, the contact area between the garbage and the air is small, requiring a longer time to ignite, resulting in lower combustion efficiency and severely affecting the incineration speed. Furthermore, some garbage contains a large amount of moisture. If moisture enters the incinerator, it greatly affects the quality of combustion. Excessive moisture can cause incomplete combustion and produce a large amount of smoke, which not only increases the degree of environmental pollution but also increases the energy consumption of the smoke extraction and environmental protection equipment. Therefore, it is necessary to crush and dry the garbage.
[0004] Existing waste-to-energy drying devices, such as the Chinese patent document with application number CN202010033171.X, can only dry the surface of the waste. However, some moisture remains inside the waste, such as yogurt packaging bags and similar types of waste. The moisture inside these bags is not easy to drain, and the drying method cannot effectively dry the moisture inside the packaging bags. Summary of the Invention

The lower end of the material passage is fixedly connected to the rectangular box.
[0015] Furthermore, the rotating drying mechanism includes a rectangular box, an air conveying section, and a drying section. The rectangular box contains a fan-shaped cavity that rotates.

[0019] The beneficial effects of this invention are: the conical cutting mechanism can quickly divide the waste, allowing it to enter the furnace in a smaller volume, increasing the contact area between the waste and air, and significantly improving combustion efficiency; while crushing the waste, it can also allow the moisture trapped inside the waste to flow out, reducing the water content of the waste, achieving dry and wet separation, and facilitating subsequent collection; it can also avoid incomplete combustion caused by excessive moisture entering the furnace, reducing the generation of flue gas and reducing the degree of environmental pollution.
[0020] The drainage section allows excess water to be discharged to the outside through the drain pipe; the agitator moves the garbage while applying positive pressure, causing the water inside the garbage to separate from the garbage (e.g., absorbent garbage such as sponges), resulting in a lower water content in the garbage and improving the subsequent drying effect.
[0021] Through the coordination and operation of the drying section and the gas supply section, the heat generated by the furnace shell can be collected and used to dry the waste, realizing heat energy recovery and utilization, and reducing the active output of heat energy; the dried waste is in a scattered state, which further improves the incineration rate.
[0022] The flue gas purification device can treat the waste smoke discharged from the flue into a harmless state, thereby controlling the degree of environmental pollution. Attached Figure Description

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0037] This application provides a municipal solid waste incineration device for power generation. Please refer to [link / reference]. Figures 1-12 It includes a waste body 1 and a furnace body 2. A conical cutting mechanism is provided above the furnace body 2, an active drainage mechanism is provided below the conical cutting mechanism, and a rotating drying mechanism is provided at the lower end of the active drainage mechanism.
[0038] The conical cutting mechanism includes a rotary motor 6, a transmission unit 7, and a cutting unit 8. The cutting unit 8 includes an active blade 9, a passive blade 10, a conical outer shell 11, and a conical inner shell 12. The rotary motor 6 drives the active blade 9 to rotate in opposite directions through the transmission unit 7.
[0039] The active drainage mechanism includes a guide section 14, a drainage section 15, and a pushing section 16. The waste body 1 is concentrated in the drainage section 15 through the guide section 14. The drainage section 15 drains the water from the waste body 1. The pushing section 16 squeezes the waste body 1 and pushes the waste body 1 to move it into the rotating drying mechanism.
[0040] The rotary drying mechanism includes a rectangular box 20, an air conveying section 21, and a drying section 22. A partition 23 is provided in the middle of the rectangular box 20 at a horizontal position. Above the partition 23 is the feeding chamber 25, and below the partition 23 is the drying chamber 24. The drying section 22 divides the drying chamber 24 into several fan-shaped chambers. The waste body 1 is located in the fan-shaped chambers. The fan-shaped chambers are in a rotating state. The air conveying section 21 conveys the hot air generated by the furnace body 2 to the feeding chamber 25 and the fan-shaped chambers.
[0041] The rotary motor 6 drives the actuating part 16 and the drying part 22 to rotate.
[0042] In practical applications, the flue gas purification device 80 is existing technology and will not be described in detail. For example, in the patent with patent number CN202210401314.7, the input end of the flue gas purification device 80 is connected to the flue duct 3. The garbage body 1 enters the conical cavity 13 through the opening at the upper end of the conical outer shell 11. The rotation of the control rotary motor 6 can drive the conical inner shell 12 and the active blade 9 to rotate. The active blade 9 and the passive blade 10 move relative to each other. When the garbage body 1 moves between the active blade 9 and the passive blade 10 and is at the same height, the shearing force between the active blade 9 and the passive blade 10 can cut the larger garbage body 1, thus achieving the purpose of cutting the garbage body 1. When the garbage body 1 falls on the upper end of the conical inner shell 12, the centrifugal force generated by the rotation of the conical inner shell 12 can throw the garbage body 1 into the conical cavity 13. In order to improve the crushing effect, the gap at the upper end of the conical cavity 13 is larger than the gap at the lower end, and the space of the garbage body 1 is in a state of getting smaller and smaller, thereby improving the crushing effect.
[0043] After being crushed, the waste body 1 falls downwards. Its falling path is circular in plan view. The waste body 1 first contacts the guide part 14. Through the action of the guide part 14, the falling path of the waste body 1 changes from circular to rectangular in plan view. The waste body 1 and the water in it fall into the water storage tank 19. The water is discharged to the outside through the drain part 15. At this time, the water storage tank 19 is in a wet state. Through the action of the agitator 16, the waste body 1 can be agitated to one side above the water storage tank 19 and falls into the drying part 22 under the action of gravity.
[0044] The waste body 1 is moved into the drying chamber 24 by the feeding chamber 25. The drying chamber 24 is rotated by the rotation of the drying section 22. During the rotation of the drying chamber 24, the air pump 69 blows the hot air generated by the furnace body 2 into the drying chamber 24, so that the waste body 1 in the drying chamber 24 is dried quickly. The hot air is discharged through the exhaust port on the surface of the support pipe 61 and the rectangular box 20. When the drying chamber 24 moves the waste body 1 to the discharge port 26, the waste body 1 moves into the furnace body 2 for incineration under the action of gravity. The heat of the furnace body 2 can be carried away by the steam coil 78, and the generated steam is used for power generation. The shape of the discharge port 26 can be appropriately modified to avoid waste remaining in the fan-shaped cavity.
[0045] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6The conical outer shell 11 has an opening at its upper end, forming a conical cavity 13 between the conical outer shell 11 and the conical inner shell 12. The active blade 9 and the passive blade 10 are located inside the conical cavity 13. The waste body 1 falls through the conical cavity 13, while the passive blade 10 remains fixed. The conical inner shell 12 is divided into an upper shell 27 and a lower shell 28. The cutting section 8 includes a bearing bracket 29 installed at the lower end of the conical outer shell 11. A bearing 30 is installed at one end of the bearing bracket 29. The lower shell 28 is installed inside the bearing 30. A support rod 31 is installed inside the lower shell 28. A rotating tube 32 is installed at the center of the support rod 31. A bevel gear 33 is installed at the lower end of the rotating tube 32. The rotating tube 32 has two... Bearing 2 34 is installed at one end, rotating tube 2 35 is installed on the inner ring of bearing 2 34, bevel gear 2 36 is installed at the lower end of rotating tube 2 35, upper shell 27 is fixedly connected to the upper end of rotating tube 2 35, active blade 9 is installed on conical inner shell 12, passive blade 10 is installed on conical outer shell 11; flue 3 is provided on one side of furnace body 2, slag discharge port 4 is provided at the lower end of furnace body 2, flue gas purification device 80 is provided on one side of flue 3, heat insulation layer 5 is provided on the outer side of furnace body 2, rectangular box 20 is fixedly installed on the upper surface of furnace body 2, water storage tank 19 is fixedly installed on the upper surface of rectangular box 20, guide part 14 is fixedly installed on the upper end of water storage tank 19, and conical outer shell 11 is fixedly installed on the upper end of guide part 14.
[0046] In practical applications, during crushing, the rotary motor 6 is controlled to rotate, which indirectly drives the driven wheel 40 to rotate. The driven wheel 40 rotates, which drives the transmission shaft 39 to rotate. The transmission shaft 39 rotates, which drives the bevel gear 41 to rotate. The bevel gear 41 drives the bevel gear 36 and the bevel gear 33 to rotate in opposite directions. The bevel gear 33 rotates, which drives the rotating tube 32 and the support rod 31 to rotate. The support rod 31 rotates, which drives the lower shell 28 and the active blades 9 on the lower shell 28 to rotate clockwise. The bevel gear 36 rotates, which drives the rotating tube 35 to rotate. The rotating tube 35 drives the upper shell 27 and the active blades 9 on the upper shell 27 to rotate counterclockwise. The opposing rotation of the top two active blades 9 can improve the crushing effect on the waste body 1 and prevent the waste body 1 from falling too quickly.
[0047] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The transmission unit 7 includes a bearing 37 mounted on the side surface of the conical housing 11, a bearing 38 mounted at the center of the guide unit 14, a transmission shaft 39 mounted on the inner ring of the bearings 37 and 38, a driven wheel 40 mounted on one end of the transmission shaft 39, and a bevel gear 41 mounted on the other end of the transmission shaft 39, which meshes with bevel gears 33 and 36 simultaneously. The bevel gear 41 is located between bevel gears 33 and 36.
[0048] In practical applications, the transmission shaft 39 rotates stably through the action of bearings 37 and 38. The bevel gear 41, located between bevel gear 33 and bevel gear 36, enables the opposing rotation of bevel gear 33 and bevel gear 36.
[0049] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 The upper end of the guide section 14 is an annular cavity 17, which is connected to the lower end of the conical cavity 13. The lower end of the guide section 14 is a rectangular cavity 18. The waste body 1 is concentrated from the annular cavity 17 into the rectangular cavity 18. The guide section 14 includes an annular outer wall 42 installed on the upper end of the water storage tank 19. An arc-shaped inclined plate 43 is installed on the inner side of the annular outer wall 42. An annular inner wall 44 is installed on the inner side of the arc-shaped inclined plate 43. An annular cavity 17 is formed between the annular inner wall 44 and the annular outer wall 42. A square frame 45 is installed on the lower end of the arc-shaped inclined plate 43. A rectangular cavity 18 is formed on the inner side of the square frame 45.
[0050] In practical applications, the falling garbage body 1 lands between the outer annular wall 42 and the inner annular wall 44. The garbage body 1 first enters the annular cavity 17 at the upper position of the outer annular wall 42. As the garbage body 1 falls, it will come into contact with the arc-shaped inclined plate 43. Under the action of the arc-shaped inclined plate 43, the garbage body 1 is concentrated together. At this time, the garbage body 1 is located at the position of the square frame 45.
[0051] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 The drainage section 15 includes a water storage tank 19 with an opening at the upper end that connects to a rectangular cavity 18. The lower end of the water storage tank 19 is arc-shaped. The drainage section 15 includes a rectangular elongated hole 46 at the center of the lower end of the water storage tank 19. A filter screen 47 is installed at the upper end of the rectangular elongated hole 46, and a water guide pipe 48 is installed at the lower end of the rectangular elongated hole 46.
[0052] In practical applications, the waste body 1 moves into the water storage tank 19 directly below the square frame 45 under the action of gravity. Excess water will flow through the filter screen 47 into the water pipe 48, and the excess water will be discharged to the outside through the water pipe 48.
[0053] Reference Figure 1 , Figure 3 , Figure 9 and Figure 10The actuating part 16 is located inside the water storage tank 19. The actuating part 16 moves the waste body 1 into the rotating drying mechanism. The actuating part 16 is in elastic contact with the water storage tank 19. The rotation axis of the actuating part 16 is at a different position from the axis of the water storage tank 19. The actuating part 16 includes bearings 49 installed on both sides of the water storage tank 19. A rotating shaft 50 is installed on the inner ring of the bearings 49. A worm gear 51 is installed at one end of the rotating shaft 50. A pin spring 52 is installed on the side surface of the rotating shaft 50. A rigid [unclear] is installed at the telescopic end of the pin spring 52. A rubber sheet 53 is provided. A vertical bearing 54 is installed on the side surface of the water storage tank 19. A second drive shaft 55 is installed on the inner ring of the vertical bearing 54. A worm gear 56 that meshes with a worm wheel 51 is installed at one end of the second drive shaft 55. A driven wheel 57 is installed at the other end of the second drive shaft 55. A drive belt 58 is installed between the driven wheel 57 and the driven wheel 40. There are two water storage tanks 19 located on both sides below the guide part 14. A feed chute 59 is installed between the water storage tanks 19. The lower end of the feed chute 59 is fixedly connected to the rectangular box 20.
[0054] In practical applications, the rotation of the rotary motor 6 indirectly drives the driven wheel 57 to rotate. The rotation of the driven wheel 57 drives the transmission shaft 55 to rotate. The rotation of the transmission shaft 55 drives the worm gear 56 at one end of the transmission shaft 55 to rotate. The worm gear 56 drives the worm wheel 51 to rotate. The rotation of the worm wheel 51 drives the rotating shaft 50 to rotate. The rotation of the rotating shaft 50 drives the ejector spring 52 and the rigid rubber plate 53 to revolve. Since the rotation axis of the rigid rubber plate 53 and the axis of the lower arc-shaped position of the water storage tank 19 are on different straight lines, such as... Figure 3 As shown, when the rigid rubber plate 53 rotates to the left, the space on the left side of the water storage tank 19 is larger, and the ejector spring 52 is in an extended state. As the ejector spring 52 rotates counterclockwise, the rigid rubber plate 53 contacts the water storage tank 19 and presses the waste body 1 tightly. As the rigid rubber plate 53 continues to rotate, the ejector spring 52 gradually shortens and stores force, while simultaneously pushing the waste body 1 above the feed chute 59. When the rigid rubber plate 53 separates from the water storage tank 19, the elastic force released by the ejector spring 52 causes the rigid rubber plate 53 to have a certain horizontal acceleration, which facilitates the separation of the waste body 1 from the rigid rubber plate 53. After separation, the waste body 1 falls through the feed chute 59 under the action of gravity. The cross-section of the rigid rubber plate 53 is L-shaped, which facilitates the squeezing and pushing of the waste body 1.
[0055] Reference Figure 1 , Figure 4 , Figure 11 and Figure 12The rotating drying mechanism includes a rectangular box 20, an air conveying section 21, and a drying section 22. The rectangular box 20 contains a fan-shaped cavity, which rotates. The air conveying section 21 delivers hot air generated by the furnace body 2 to the feeding chamber 25 and the fan-shaped cavity. A rotary motor 6 drives the actuating section 16 and the drying section 22 to rotate. A partition 23 is located horizontally in the middle of the rectangular box 20. Above the partition 23 is the feeding chamber 25, and below the partition 23 is the drying chamber 24. The drying section 22 divides the drying chamber 24 into several fan-shaped cavities. The waste body 1 is located within one of these fan-shaped cavities. A rectangular opening 79 is located on the upper surface of the rectangular box 20, directly below the actuating section 16. A discharge port 26 is located on the lower surface of the rectangular box 20, communicating with the furnace body 2. The top view projections of the rectangular opening 79 and the discharge port 26 are different. In the drying state, the drying section 22 is located inside the drying chamber 24. The drying section 22 includes a bearing 60 installed on the lower surface of the partition plate 23 and the lower surface of the rectangular box 20. A support tube 61 is installed on the inner ring of the bearing 60. A rectangular plate 62 is installed on the side surface of the support tube 61. The rectangular plate 62 divides the drying chamber 24 into a fan-shaped cavity. A worm gear 63 is installed at the lower end of the support tube 61. A bearing 64 is installed on the lower surface of the rectangular box 20. A drive shaft 65 is installed on the inner ring of the bearing 64. A worm 66 that meshes with the worm gear 63 is installed at one end of the drive shaft 65. A drive wheel 67 is installed at the other end of the drive shaft 65. A drive belt 68 is installed between the drive wheel 67 and the driven wheel 57. A rotary motor 6 is installed on the upper surface of the furnace body 2. The rotating end of the rotary motor 6 is fixedly connected to the drive wheel 67.
[0056] In practical applications, the waste body 1 first enters the feeding chamber 25 after falling through the feeding chute 59 and lands on the upper surface of the guide plate 75. The guide plate 75 causes the waste body 1 to enter the fan-shaped cavity through the rectangular opening 79. The rotation of the rotary motor 6 drives the transmission wheel 67 and the transmission shaft 65 to rotate. The bearing 64 makes the rotation of the transmission shaft 65 more stable. The rotation of the transmission shaft 65 drives the worm gear 63 to rotate. The rotation of the worm gear 63 drives the support tube 61 to rotate. The support tube 61 drives the rectangular plate 62 to revolve. The fan-shaped cavity rotates with the rotation of the rectangular plate 62. After the waste body 1 rotates with the rectangular plate 62 for a certain angle, it finally moves to the position of the discharge port 26. Under the action of gravity, the waste body 1 falls into the furnace body 2, realizing the incineration after drying.
[0057] Reference Figure 1 , Figure 4 , Figure 11 and Figure 12The gas supply unit 21 includes an air pump 69 installed at one end of the upper surface of the furnace body 2. The furnace body 2 is provided with an insulation layer 5. A coil 70 is installed on the outside of the insulation layer 5. A dust cover 71 is installed at one end of the coil 70. The other end of the coil 70 is fixedly connected to the input end of the air pump 69. An annular groove 72 is installed on the lower side surface of the rectangular box 20. A connecting pipe 73 is installed between the annular groove 72 and the output end of the air pump 69. A vent hole 74 is opened on the side surface of the rectangular box 20. The vent hole 74 connects the annular groove 72 and the fan-shaped cavity. A guide plate 75 is installed on the upper surface of the partition plate 23. A second vent hole 76 is opened on the side surface of the guide plate 75. A trapezoidal cavity is formed between the guide plate 75 and the rectangular box 20. A connecting pipe 77 is installed between the annular groove 72 and the trapezoidal cavity. The guide plate 75 is located below the rectangular opening 79.
[0058] In practical applications, when the waste body 1 passes through the drying section 22, the air pump 69 is controlled to work. The air pump 69 draws air from one end of the dust cover 71 through the coil 70. The coil 70 moves the heat outside the furnace body 2 into the air pump 69. The air pump 69 inputs the hot air into the annular groove 72. The annular groove 72 delivers the hot air to the vent 74. The hot air enters the fan-shaped cavity through the vent 74, thus drying the waste body 1 in the fan-shaped cavity.
[0059] The vent 74 is positioned to avoid the discharge port 26 and the rectangular opening 79, thus preventing the airflow from blowing up the falling waste body 1 and affecting the falling efficiency of the waste body 1.
[0060] Reference Figure 1 The furnace body 2 is equipped with a steam coil 78.
[0061] In practical applications, a large amount of water is injected into the steam coil 78, and water vapor is generated in the steam coil 78 through the combustion of the furnace body 2, which is then used for power generation.
[0062] Reference Figure 5 The active blade 9 and the passive blade 10 are arc-shaped, and both ends of the active blade 9 and the passive blade 10 are semi-circular notches with sharpening treatment.
[0063] In practical applications, the semi-circular notches at both ends of the active blade 9 and the passive blade 10 prevent the waste body 1 from falling off when it is clamped, thus improving the stability of crushing.
