[0002] Waste-to-energy is a clean energy technology that converts domestic waste into electricity through incineration or gasification. It has the dual environmental benefits of reducing the amount of landfill and reusing resources. However, a large amount of acidic gases, such as sulfur dioxide (SO2) and hydrogen chloride (HCl), are produced during the incineration process. If these acidic gases are not treated, direct emission will cause serious pollution to the atmospheric environment. For this reason, waste incineration power plants generally need to be equipped with exhaust gas treatment systems to remove or neutralize these harmful gases.

[0003] As an efficient and inexpensive alkaline absorbent, slaked lime (calcium hydroxide) is widely used in flue gas desulfurization and acid gas purification in waste-to-energy. It reacts with acid gases to generate harmless solid compounds to purify waste gas. The high reactivity and excellent acid gas neutralization ability of slaked lime make it an indispensable environmentally friendly material in waste-to-energy.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0041] Embodiment 1:

[0042] like Figure 1-6As shown, a slaked lime storage system of the present invention comprises: a storage tank 1, a feed port 11 is arranged on the top of the storage tank 1, a smoke exhaust pipe 12 is arranged on one side of the feed port 11, and a dust collecting tank 13 is arranged above the smoke exhaust pipe 12; a material distribution part 2, the material distribution part 2 comprises a driving component 21 and a material distribution plate 22 installed inside the storage tank, and a supporting component 23 fixed to the inner wall of the storage tank, the supporting component 23 is used to support the bottom of the material distribution plate 22, a discharge plate 24 is arranged on the material distribution plate 22, a first strong magnet 241 is arranged on the discharge plate 24, the driving component 21 is used to drive the material distribution plate 22 to rotate, a first rod body 3 is fixed to the bottom of the driving component 21, a second suction plate 4 is slidably installed at the bottom of the driving component 21 and located above the first rod body 3, and a second strong magnet 41 is installed on the second suction plate 4.

[0043] When the system starts working, the transport vehicle delivers slaked lime into the storage tank 1 through the feed port 11. During the material feeding process, the smoke exhaust pipe 12 discharges the dust generated during the feeding process through the dust collecting tank 13. After the driving component 21 of the material distribution part 2 is started, the material distribution plate 22 is driven to rotate, so that the slaked lime falls evenly onto the material distribution plate 22. Since a discharge plate 24 with a first strong magnet 241 is installed on the material distribution plate 22, the upper slaked lime can be dropped into the storage tank 1 when the discharge plate 24 is opened. When the first rod body 3 pushes the second suction plate 4 to slide, the second strong magnet 41 on the second suction plate 4 and the first strong magnet 241 attract each other. When the second strong magnet 41 separates from the first strong magnet 241, the second strong magnet 41 opens the discharge plate 24 to discharge the slaked lime, which can reduce the generation of dust. At the same time, the slaked lime can be evenly distributed in the storage tank 1 to prevent the slaked lime from being squeezed and accumulated to form agglomerates.

[0044] A plurality of cross bars 221 are provided on the material distribution plate 22 , and a material drop opening 222 is formed between two cross bars 221 . A discharge plate 24 is hinged at the bottom of the cross bar 221 , and a first spring 223 is fixed between the discharge plate 24 and the cross bar 221 , wherein two discharge plates 24 block the material drop opening 222 .

[0045] By hingedly connecting the discharge plate 24 at the bottom of the cross bar 221, the discharge plate 24 is used to control the opening and closing of the drop port 222. When the drop port 222 is opened, the discharge plate 24 is V-shaped and is pulled to reset by the first spring 223. The discharge plate 24 allows the slaked lime to first cover the discharge plate 24 before falling, thereby reducing the generation of dust. At the same time, after falling, it can be closed by the discharge plate 24 to reduce the overflow of dust.

[0046] The driving assembly 21 includes a support plate 211 fixed inside the storage tank 1 and a motor 212 installed at the bottom of the support plate 211, a rotating shaft 213 is installed at the bottom of the motor 212, a first through hole 42 is opened in the middle of the second suction plate 4, the first through hole 42 is sleeved on the rotating shaft 213, a second rod body 214 is fixed on the rotating shaft 213, the second rod body 214 is located above the second suction plate 4, two baffles 224 are fixed on the top of the material balancing disk 22, the two baffles 224 are arranged in parallel, and in the initial position, the second rod body 214 is located between the two baffles 224, and the second rod body 214 rotates to drive the baffle 224 and the material balancing disk 22 to rotate.

[0047] The motor 212 drives the rotating shaft 213 to rotate. The rotation of the rotating shaft 213 will push the second rod body 214 to contact the baffle 224, and then push the baffle 224 and the material balancing plate 22 to rotate synchronously. The material balancing plate 22 rotates smoothly. When a certain weight of slaked lime is accumulated on the material balancing plate 22 and it drops, the second rod body 214 is separated from the baffle 224. After the slaked lime on the material balancing plate 22 falls, the material balancing plate 22 is reset to drive the material balancing plate 22 to continue rotating.

[0048] A second through hole 25 is provided on the discharge plate 24 located on the central axis of the material balancing disk 22, and the bottom of the rotating shaft 213 passes through the material balancing disk 22. A first support block 26 is fixed to the inner wall of the storage tank 1, and a first plug hole 261 is provided on the first support block 26. A first plug rod 262 is inserted into the first plug hole 261. The top of the first plug rod 262 is fixed to the bottom of the second suction plate 4, and a second spring 263 is sleeved on the first plug rod 262; block blocks 31 are fixed on both sides of the top of the first rod body 3, and the block block 31 is provided with an inclined surface 32. When the rotating shaft 213 drives the first rod body 3 to rotate, the block block 31 pushes the second suction plate 4 to move upward, and the second strong magnet 41 contacts the first strong magnet 241.

[0049] The motor 212 drives the rotating shaft 213 to rotate, and then drives the first rod body 3 to rotate. As the first rod body 3 rotates, the blocks 31 on both sides of the top push the second suction plate 4 to move upward through their inclined surfaces 32. When the second suction plate 4 rises to a certain height, the second strong magnet 41 on the second suction plate 4 contacts the first strong magnet 241 on the discharge plate 24. When the inclined surface 32 is separated from the second suction plate 4, the second strong magnet 41 pulls the first strong magnet 241, so that the discharge plate 24 rotates around the hinge axis and opens, allowing the slaked lime to fall evenly through the material distribution plate 22.

[0050] When the material-distributing plate 22 rotates to receive the material, the gravity increases and the plate will naturally drop, pressing the support plate 235 to drop. At the same time, the up and down movement of the rod will compress or release the third spring 234. The spring can automatically reset according to the force conditions. When the material-distributing plate drops, it moves closer to the slaked lime at the bottom and then releases the slaked lime above it, which can shorten the falling distance of the slaked lime and reduce dust generation.

[0051] The support assembly 23 includes a second support block 231 fixed to the inner wall of the storage tank 1, the second support block 231 is provided with a second plug hole 232, the second plug hole is installed with a second plug rod 233, the second plug rod 233 is sleeved with a third spring 234, and a support plate 235 is fixed to the top of the first plug rod 262.

[0052] The second support block 231 is fixed on both sides of the inner wall of the storage tank 1, and is used to support the second insertion rod 233. The support plate 235 on the top of the second insertion rod 233 is used to support the edge of the material distribution tray 22. When the material distribution tray 22 bears a certain weight, the second insertion rod 233 compresses the third spring 234 and moves downward along the second insertion hole 232.

[0053] The gas delivery part 5 includes a first pipeline 51 and a second pipeline 52. The first pipeline 51 and the second pipeline 52 are both provided with a first valve 53. A sulfiding air 54 is provided on one side of the first valve 53. A heating pipe 55 is provided on one side of the sulfiding air 54. One end of the second pipeline 52 is connected to the storage tank 1, and one end of the first pipeline 51 is connected to the dust collecting tank 13. A filter screen 14 is provided inside the dust collecting tank 13.

[0054] The compressed air is controlled to enter the first pipeline 51 and the second pipeline 52 through the first valve 53. When the second valve 16 is opened, the compressed air is mixed with the sulfiding air 54 and passed into the storage tank 1. The sulfiding air 54 has multiple functions of preventing slaked lime from agglomerating, maintaining material fluidity, reducing dust accumulation, preventing chemical reactions, maintaining air pressure balance, improving desulfurization efficiency and enhancing safety. By adjusting the gas flow, the sulfiding air 54 helps optimize the storage conditions of slaked lime and ensures its efficient processing and use in various industrial applications.

[0055] When the sulfiding air 54 needs to be heated, the heating pipe 55 is turned on to heat the sulfiding air 54. The heated sulfiding air 54 can better prevent the slaked lime from agglomerating.

[0056] A discharge pipe 15 is provided at the bottom of the storage tank, and a second valve 16 is provided on the discharge pipe 15; the pulping section 6 includes a weighing screw conveyor 61 connected to the discharge pipe 15 and a third valve 62, and the weighing screw conveyor 61 is connected to the pulping tank.

[0057] When the system needs to make pulp, slaked lime flows out from the storage tank 1 through the discharge pipe 15. The second valve 16 is responsible for adjusting the initial outflow of the material. The slaked lime enters the weighing screw conveyor 61 through the discharge pipe 15. The conveyor is not only responsible for conveying the material to the pulping tank, but also can weigh the material in real time to ensure that the conveying amount of slaked lime meets the ratio requirements. During the material conveying process, the third valve 62 further controls the flow rate of the material to ensure that the slaked lime can enter the pulping tank in an appropriate amount and be fully mixed with water to form a slurry.

[0058] Embodiment 2:

[0059] The present invention can also only set the material distribution plate 22 according to needs, and cancel the first support block 26, the first plug hole 261, and the first plug rod 262. When a certain amount of slaked lime is accumulated on the material distribution plate 22, the first spring 223 is subjected to a certain weight, and the discharge plate 24 rotates to open.

[0060] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
