Description

Technical Field

[0001] The present invention relates to the field of garbage processing equipment, and in particular to a garbage incinerator and a garbage incineration production line having the garbage incinerator. Background Art

[0002] The traditional method of domestic waste disposal is landfill, although it has the short-term advantages of less investment, simple process, large processing capacity, and better realization of surface harmlessness.

[0003] However, landfill waste is not treated harmlessly, leaving behind a large number of bacteria and viruses. It also poses hidden dangers such as methane and heavy metal pollution. Leachate from the landfill can also permanently contaminate groundwater resources. Therefore, this method is potentially extremely harmful and will bring endless troubles to future generations. Not only does this method fail to achieve resource-based treatment of waste, but it also occupies a large amount of land, dangerously preserving a source of pollution for future generations.

[0004] Currently, many developed countries have banned landfilling of garbage. The competent departments at all levels of the Chinese government have gradually come to understand the problems of this treatment technology and are determined to ban and eliminate such practices.

[0005] Waste-to-energy incineration burns household waste at high temperatures, converting combustible waste into carbon dioxide and water. The resulting waste heat is used to generate electricity, while the resulting waste gas and fly ash are harmlessly treated.

[0031] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0032] refer to Figure 1 The embodiment of the present invention discloses a waste incineration production line, which is equipped with a waste incinerator, a boiler, a steam turbine, and a generator in sequence.

[0033] Garbage is burned in a garbage incinerator. The heat from the garbage incineration is transferred to the boiler to heat the water in the boiler, thereby generating hot steam. The hot steam enters the steam turbine to convert thermal energy into mechanical kinetic energy, and then drives the generator to move through mechanical linkage to generate electricity.

[0034] The waste slag produced after the garbage is burned in the garbage incinerator is transported out by the slag discharger, then screened by the screening machine, and then the ash is processed into resources.

[0035] The waste gas in the garbage incinerator enters the deacidification tower, and is discharged into the atmosphere through the chimney after being deacidified, dusted, and freed of dioxins and other harmful substances by the flue gas purification system.

[0036] refer to Figure 2-9 The waste incinerator includes a furnace body 1. The upper end of the furnace body 1 is provided with a feed port 2, through which waste enters the furnace body 1 for combustion. A hot gas exhaust pipe 5 is fixedly provided at the upper end of the furnace body 1, and an air intake pipe 42 is fixedly provided at the lower end of the furnace body 1. Air enters the furnace body 1 through the air intake pipe 42, and then the hot gas from the burning waste enters the boiler through the hot gas exhaust pipe 5 to heat the water in the boiler.

[0037] The furnace body 1 is fixedly provided with a partition 3 below the seventh linkage gear 40. A plurality of rotating rings are rotatably provided on the partition 3. In this embodiment, the plurality of rotating rings specifically include, from the inside out, a first rotating ring 11, a second rotating ring 12, a third rotating ring 13, a fourth rotating ring 14, and a fifth rotating ring 15. The first rotating ring 11, the second rotating ring 12, the third rotating ring 13, the fourth rotating ring 14, and the fifth rotating ring 15 are coaxially arranged and sequentially nested.

[0038] A plurality of stirring rods 17 are fixedly mounted on the upper end surfaces of the first rotating ring 11 , the second rotating ring 12 , the third rotating ring 13 , the fourth rotating ring 14 , and the fifth rotating ring 15 .

[0039] A corresponding linkage ring 20 is provided on the partition 3 corresponding to the above-mentioned rotating ring. Figure 4-6Taking the first swivel 11 as an example, the linkage ring 20 is rotatably set on the partition 3 through a bearing (not shown in the figure), the first swivel 11 can be slid up and down on the linkage ring 20, and the linkage ring 20 and the first swivel 11 are coaxially arranged.

[0040] The linkage ring 20 is provided with a plurality of slide grooves 21, and the slide grooves 21 extend in the up-down direction. A slider 26 is fixedly provided on the first rotating ring 11, and the slider 26 can slide up and down in the slide groove 21. The linkage ring 20 is fixed with a convex edge 27 at the top of the slide groove 21, and the lower end surface of the convex edge 27 can be abutted against the upper end surface of the slider 26 to prevent the slider 26 from upwardly escaping from the slide groove 21.

[0041] refer to Figure 2 The furnace body 1 is rotatably provided with a drive shaft 6, and the furnace body 1 is provided with a motor 39 for driving the drive shaft 6 to rotate. The drive shaft 6 is fixedly provided with a plurality of first drive gears 28, and the two sides of the first drive gear 28 are fixedly provided with gear rings. Figure 5 、 9 The linkage ring 20 is coaxially provided with a third linkage gear 25, which meshes with the ring gear on one side of the first drive gear 28 for transmission. A fourth linkage gear 29 is rotatably provided on the partition plate 3, which meshes with the ring gear on the other side of the first drive gear 28 for transmission. The third linkage gear 25 on the linkage ring 20 corresponding to the second rotating ring 12 meshes with the fourth linkage gear 29 for transmission. The slider 26 is disposed within the slide slot 21. When the linkage ring 20 rotates, it drives the corresponding first rotating ring 11 or second rotating ring 12 to rotate. That is, when the first drive gear 28 rotates, it simultaneously drives the first rotating ring 11 and the second rotating ring 12 to rotate, and the second rotating ring 12 and the first rotating ring 11 rotate in opposite directions on the same axis.

[0042] The driving shaft 6 drives the third rotating ring 13 and the fourth rotating ring 14 to rotate in opposite directions on the same axis through the same rotation driving mechanism, and drives the fifth rotating ring 15 to rotate at the same time.

[0043] The partition 3 is provided with a fixed ring 22 corresponding to each rotating ring. Figure 4 Taking the first rotating ring 11 as an example, the fixing ring 22 is fixedly arranged on the partition 3. The fixing ring 22 and the rotating ring are fixedly arranged coaxially. The upper end surface of the fixing ring 22 is fixedly provided with a plurality of first protrusions 23. In this embodiment, the number of the partitions 3 is three and they are arranged around the central axis of the fixing ring 22. The lower end surface of the first rotating ring 11 is provided with a second protrusion 24 corresponding to the first protrusion 23. When the first rotating ring 11 rotates, the reference Figure 7 The first protrusion 23 and the second protrusion 24 press against each other, causing the first rotating ring 11 to slide upward.

[0044] When the first driving gear 28 drives the linkage ring 20 to rotate, the linkage ring 20 drives the first rotating ring 11 to rotate, and then acts on the cooperation between the first protrusion 23 and the second protrusion 24, the first rotating ring 11 can reciprocate up and down while rotating.

[0045] When garbage falls on the upper end surface of each rotating ring and is burned, the motor 39 can be turned on at an appropriate time to drive each rotating ring to rotate and slide up and down. A stirring rod 17 is also provided on the upper end surface of the rotating ring. When the rotating ring rotates, it stirs the garbage, causing it to turn over and flatten. The shaking further enhances the turning and flattening effect, making the garbage burn more fully.

[0046] A plurality of rotating rings are provided with ash-falling through holes 16 for the waste slag to fall downwards and then be transported out by the slag discharger.

[0047] refer to Figure 2 A high-pressure gas pipe 4 is fixedly provided on the furnace body 1 below the partition 3, and a ball valve 7 for controlling the on and off of the high-pressure gas pipe 4 is provided on the high-pressure gas pipe 4. A first linkage gear 8 is fixedly provided on the drive shaft 6, and a linkage shaft 9 is rotatably provided on the furnace body 1. A first gear is fixedly provided on one side of the linkage shaft 9, and the first gear is engaged with the first linkage gear 8 for transmission. A second gear is fixedly provided on the other side of the linkage shaft 9, and a second linkage gear 10 is fixedly provided on the valve stem of the ball valve 7, and the second linkage gear 10 is engaged with the second gear for transmission.

[0048] When the driving shaft 6 drives the rotating ring to rotate and slide up and down, it can synchronously drive the ball valve 7 to open or close. When the rotating ring shakes up the garbage, the ball valve 7 opens, and the high-pressure gas in the high-pressure gas pipe 4 generates a gas impact from bottom to top on the ash drop hole 16, flushing out the waste residue blocked in the ash drop hole 16, avoiding the ash drop hole 16 from being blocked and unable to discharge the waste residue smoothly.

[0049] refer to Figure 2 The partition plate 3 is rotatably provided with a vertical shaft 30, on which a plurality of first stirring blades 31 are fixedly provided. An eighth linkage gear 41 is fixedly provided on the vertical shaft 30, and a seventh linkage gear 40 is fixedly provided on the drive shaft 6. The seventh linkage gear 40 and the eighth linkage gear 41 are engaged and driven. When the drive shaft 6 rotates, the vertical shaft 30 is driven to rotate.

[0050] refer to Figure 8The furnace body 1 is fixedly provided with a connecting portion 36 via a connecting rod 37. A rotating shaft 35 is rotatably provided on the upper end surface of the connecting portion 36. A plurality of second stirring blades 32 are provided on the rotating shaft 35. A sixth linkage gear 34 is coaxially fixedly provided on the rotating shaft 35. A fifth linkage gear 33 is fixedly provided on the vertical shaft 30. A seventh linkage gear 38 is rotatably provided on the connecting portion 36. The seventh linkage gear 38 meshes with the fifth linkage gear 33 and the sixth linkage gear 34. When the vertical shaft 30 rotates, the rotating shaft 35 is driven to rotate in the opposite direction. That is, when the vertical shaft 30 rotates, the second stirring blades 32 and the first stirring blade 31 are driven to rotate in the same direction and in the opposite direction.

[0051] The first stirring blade 31 and the second stirring blade 32 are located between the feed inlet 2 and the rotating ring. When the garbage falls from the feed inlet 2, the first stirring blade 31 and the second stirring blade 32 break it up. As it falls, the broken garbage can be pre-dried and partially burned, improving combustion efficiency. This allows the garbage to fall more evenly onto the rotating ring and reduces garbage clumping.
