Description

Technical Field

[0001] The invention relates to the technical field of waste treatment, and in particular to a fly ash solidification device for power generation from incineration of domestic waste. Background Art

[0002] With the surge in the production of urban solid waste, incineration power generation technology has been widely used in some large cities in my country as an effective treatment method. However, the fly ash produced during the incineration process is rich in high concentrations of heavy metals and highly toxic organic pollutants such as dioxins, and is regarded as hazardous waste. In order to reduce the secondary pollution caused by these fly ashes to the environment, they must be properly treated, and fly ash solidification devices came into being.

[0003] The applicant has found that in the process of mixing fly ash and cement powder, most of the existing technologies directly add all the fly ash and cement powder into the mixture. This approach may have some disadvantages. When a large amount of fly ash and cement powder are added to the mixing equipment at one time, the large amount of materials and limited mixing time may cause uneven mixing. The distribution of fly ash and cement powder in the mixture may be uneven, affecting the curing effect. In addition, mixing a large amount of materials at one time requires greater stirring force and stirring time, which increases the energy consumption of the equipment. At the same time, uneven mixing may require additional stirring or processing steps, further increasing energy consumption. Due to uneven mixing, the quality of the cured product may be unstable. The proportion and mixing ratio of fly ash and cement powder are not uniform.

[0004] Factors such as uniformity directly affect the strength and stability of the solidified body. At the same time, traditional fly ash solidification devices usually require multiple motors or other power equipment to drive stirring and chelating agent spraying operations, which not only increases the complexity of the equipment, but also increases energy consumption, which is not conducive to energy conservation and environmental protection.

[0038] 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.

[0039] Examples, such as Figure 1-Figure 10As shown, a fly ash solidification device for power generation from incineration of domestic waste provided by the present invention comprises: a gantry 1, two brackets 11 are installed on the top of the gantry 1, and a bracket 2 12 is docked on each side, two feed boxes 14 are installed on the inner sides of the two brackets 11, motors 13 are installed on the two brackets 2 12, and inclined flushing pipes 15 are installed on the lower ends of the opposite sides of the two feed boxes 14, the middle of the flushing pipe 15 is horizontally designed, and the other end of the flushing pipe 15 faces downward and passes through the top of the premixing tube 16, the outlet ends of the two flushing pipes 15 are close to each other, and the bottom of the premixing tube 16 is docked with a temporary A material storage box 17, the bottom of the temporary material storage box 17 is connected to the mixing device 19 on the inner side of the gantry 1 through an inclined tube 18, and a solenoid valve is provided at the upper end of the inclined tube 18, that is, near the lower end of the temporary material storage box 17, and a negative pressure material extraction component 2 is connected to one side of the temporary material storage box 17, and the negative pressure material extraction component 2 includes a driving arm 21 installed at the bottom of the motor 13, and a block 22 is connected to the bottom of the driving arm 21, and the block 22 fits in the frame opening of the long frame plate 23, and the frame opening is rectangular in design. A square rod 24 is provided on one side of the long frame plate 23, and the square rod 24 is inserted from an opening on one side of the air cylinder 25 for sliding. The cylinder 25 is placed in the groove of the horizontal plate 110, and a clamp block 111 is nailed on the top of the horizontal plate 110. The clamp block 111 is fixedly connected to the clamp of the cylinder 25. The horizontal plate 110 is fixed to the inside of the gantry 1 and fixed to the bottom of the docking bracket 11. The exhaust pipe 26 at one end of the cylinder 25 penetrates into the temporary storage box 17. The side wall of the cylinder 25 is also provided with an exhaust pipe 27. Both the exhaust pipe 26 and the exhaust pipe 27 are designed as one-way valve pipes. The exhaust pipe 26 can only transport gas to the inside of the cylinder 25, while The air outlet pipe 27 can only discharge the gas inside the air cylinder 25. This is an existing design and its detailed structure is not described in detail in the figure and text. One end of the air outlet pipe 27 is connected to the mixing device 19 with a spray assembly 3, which is used to automatically transport the chelating agent to the inside of the mixing device 19. The long frame plate 23 is connected to the mixing device 19 with a stirring assembly 4, which is used to fully stir the material inside the mixing device 19. A closing assembly 5 is installed at the circular opening on the top of the premixing cylinder 16, which is used to close or open the circular opening. A filter can be installed in the circular opening, and the closing assembly 5 is in a closed state when the exhaust pipe 26 is evacuating air.

[0040] Through the above-mentioned negative pressure extraction component 2 and the punching pipe 15 and the premixing cylinder 16 and other related structural designs, when the present invention is working, a small amount of cement powder and fly ash that can be easily and evenly mixed are first introduced into the mixing device 19 for mixing, and a certain amount of cement powder and fly ash are respectively introduced into the two feeding boxes 14. After that, when the motor 13 is started, it will drive the block 22 to reciprocate in the frame opening of the long frame plate 23 through the driving arm 21. This reciprocating motion in turn pushes the square rod 24 and its piston to slide in the air cylinder 25 to generate negative pressure. When the square rod 24 moves in one direction, such as the direction of exhaust, negative pressure can be generated inside the temporary storage box 17 through the exhaust pipe 26. At this time, the solenoid valve at the upper end of the inclined tube 18 is closed, the closing component 5 is in a closed state, and the exhaust A filtering structure can be designed at the mouth of the air pipe 26 to avoid adsorption of dust. Then, an inclined flushing pipe 15 is installed at the lower end of the opposite side of the two feed boxes 14, and cement powder and ash powder can be transported out through negative pressure. The middle part of the flushing pipe 15 is horizontally designed, and the other end thereof is downward and passes through the top of the premixing barrel 16. The outlet ends of the two flushing pipes 15 are close to each other, so that the cement powder and fly ash powder falling from the feed box 14 can be preliminarily hedged and mixed in the flushing pipe 15 and concentrated in the temporary storage box 17, and the exhaust is discharged unidirectionally through the outlet pipe 27. In this way, quantitative hedge mixing can be carried out continuously and uninterruptedly. After a certain amount is concentrated, the solenoid valve of the inclined pipe 18 is opened to discharge these materials into the mixing device 19 for mixing and stirring.

[0041] The inner wall of the temporary storage box 17 is equipped with a filter frame plate 28 that surrounds the pipe mouth of the exhaust pipe 26. One side of the filter frame plate 28 is inclined and equipped with a filter screen. An inclined plate 112 is installed on both sides of the inner wall of the two feed boxes 14, and the bottom end of the inclined surface of the inclined plate 112 below is below the inlet of the punching pipe 15.

[0042] In the pre-mixing optimization design, the inclined mesh of the filter frame plate 28 can prevent the exhaust pipe 26 from sucking in dust, and the inclined design makes it easy for the dust to slide down the inclined surface when there is no exhaust. The design of the inclined plate 112 prevents the dust at the punching pipe 15 from being squeezed too much, making it convenient to guide the dust out for counter-mixing and improving efficiency. For details, see Figure 7 .

[0043] The liquid spraying assembly 3 includes an air compressor 31 installed on one side of the gantry 1, and the air outlet pipe 27 is connected to the air inlet end of the air compressor 31. A timing electric valve 34 is installed on the compression jet pipe 33 of the air compressor 31, and the other end of the compression jet pipe 33 is designed as a contraction port 35, and the contraction port 35 is connected to an atomizing nozzle 37 through a straight pipe. The atomizing nozzle 37 is located on the inner side of the mixing device 19. A vertical thin tube 36 is installed at the bottom of the straight tube. The thin tube 36 is inserted into the lower end of the liquid tank 32 containing the chelating agent and is inserted from the top. The atomizing nozzle 37 is located on the outlet side of the inclined tube 18, and the timing electric valve 34 is opened and closed synchronously with the solenoid valve at the upper end of the inclined tube 18.

[0044] By designing the liquid spraying assembly 3 , the air compressor 31 can receive the gas sprayed from the outlet pipe 27 , compress and collect it, and intermittently deliver the high-pressure gas into the compression injection pipe 33 through the control of the timing electric valve 34 . This design ensures that the gas can be output at a certain pressure and frequency, providing a stable gas source for subsequent liquid atomization. When the high-pressure gas flows through the contraction port 35, due to the sudden reduction in the caliber, the gas flow rate increases, and the pressure is further enhanced, creating ideal conditions for the subsequent atomization process. At the same time, the capillary 36 is a key component connecting the liquid tank 32 and the atomizing nozzle 37. Its design of vertically inserting into the bottom of the liquid tank helps to ensure that the chelating agent can be evenly and continuously sucked. With the action of the high-pressure gas, the chelating agent in the liquid tank 32 is sucked in through the capillary 36 and meets the high-speed airflow at the atomizing nozzle 37. Under the action of the strong airflow shear force, the chelating agent is dispersed into tiny droplets to form a fine mist spray, which undergoes a catalytic reaction, so that the cement powder and the ash powder fully react and solidify. In this way, the negative pressure extraction component 2 and the liquid spray component 3 are linked without the need for an additional suction pump, and the timing electric valve 34 is synchronously opened and closed with the solenoid valve at the upper end of the inclined tube 18, so that spraying can be performed while feeding, thereby fully mixing, and also realizing automatic continuous spraying with higher efficiency.

[0045] The stirring assembly 4 includes two stirring shafts 41 rotatably connected to the bottom end of the mixing device 19, and stirring plates 42 are installed on both sides of the stirring shafts 41, and the stirring plates 42 are staggered. Two gears 43 are rotatably installed on the top of the mixing device 19, and the two gears 43 share a rotating shaft with the two stirring shafts 41. One side of the two gears 43 is engaged with a tooth plate 44, and the tooth plate 44 is fixed to the bottom of the long frame plate 23 through a connecting plate. There is a slider on the outside of the tooth plate 44, and the slider slides in the inner slideway of the gantry 1.

[0046] By designing the stirring assembly 4, when the negative pressure pumping assembly 2 is in operation, the long frame plate 23 reciprocates in a straight line, which also causes the tooth plate 44 to move back and forth, and each back and forth movement causes the gear 43 to rotate one circle, and then causes the stirring plates 42 of the two stirring shafts 41 to rotate back and forth for stirring. This movement mode not only makes the stirring more uniform, but also can effectively prevent the material from forming a dead angle inside the mixing device 19, ensuring that the material can be fully mixed. Secondly, the energy-saving effect of the stirring assembly 4 is also very significant. Since it is completely driven by the power generated by the negative pressure pumping assembly 2 when it is working, no additional motor or other power equipment is required, thereby greatly reducing energy consumption.

[0047] The closing assembly 5 includes a U-shaped frame 51 fixed at the circular opening at the top of the premixing cylinder 16. The bottom of the U-shaped frame 51 is connected to the top of the premixing cylinder 16 with two sliding rods 52. The sliding rods 52 pass through the rod holes of the closing plate 53, and the top of the closing plate 53 is connected to the U-shaped frame 51 with a spring 54. In normal state, the spring 54 applies a pulling force to the closing plate 53, so that the closing plate 53 cannot close the circular opening.

[0048] By designing the closing component 5, during suction, the closing plate 53 overcomes the elastic force of the spring 54 through pressure, and slides down through the slide rod 52 to fit the closed circular opening on the top surface of the premixing cylinder 16 to prevent external air from entering, so that the suction force received by the punching tube 15 is stronger, making it easier to suck out dust. When the air outlet pipe 27 releases air, the closing plate 53 moves up to facilitate the entry of gas and avoid uneven air pressure in the premixing cylinder 16.

[0049] 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.
