Description

Technical Field

[0001] The present invention relates to the technical field of garbage disposal, and more specifically, to an intelligently regulated fly ash resource coupling treatment system. Background Art

[0002] At present, the main methods of garbage disposal are landfill and incineration. As for landfill, it not only occupies a large amount of land resources, but also, as time goes by, the number of uncontrollable factors in the landfill increases, which may cause the leakage of toxic substances such as leachate, causing pollution hazards to the soil and groundwater; although garbage incineration can reduce the amount of garbage and recycle it, it will produce a large amount of fly ash, which is a toxic substance and has a complicated treatment procedure.

[0003] At present, common fly ash treatment systems mostly need to go through water washing and pyrolysis. Water washing and pyrolysis can remove soluble chloride salts and dioxins in fly ash respectively, and dioxin-like substances and organic substances produced by pyrolysis can be burned for secondary combustion. The heat energy produced by combustion can be used for pyrolysis of fly ash after water washing, thereby realizing resource-coupled treatment process. In the pyrolysis process, it is often divided into low-temperature pyrolysis and high-temperature pyrolysis processes. During low-temperature pyrolysis, fly ash is mobile pyrolyzed in a screw conveyor, but the pyrolysis effect is not good, the fly ash is heated unevenly, and it is easy to stick to the spiral conveyor blades. Over time, a hardened fly ash coating layer will be produced on the spiral conveyor blades, resulting in a significant reduction in the thermal conductivity of the central axis area, resulting in a reduction in the amount of dioxins produced by low-temperature pyrolysis, thereby increasing the energy consumption of subsequent high-temperature pyrolysis and reducing production efficiency.

[0018] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only intended to enable those skilled in the art to better understand and implement the subject matter described herein. In addition, the features described relative to some examples may also be combined in other examples.

[0019] like Figure 1-Figure 4 as well as Figure 9-11 As shown, an intelligent control type fly ash resource coupling treatment system includes a fly ash water washing unit, a filter press unit connected to the fly ash water washing unit, a low-temperature pyrolysis unit connected to the filter press unit, and a high-temperature pyrolysis unit connected to the low-temperature pyrolysis unit, and the low-temperature pyrolysis unit includes a mounting bracket 1, a power drive mechanism 2 connected to the mounting bracket 1, a transmission mechanism 3 and a spiral conveying pyrolysis mechanism 4, an external heating mechanism 5 sleeved on the spiral conveying pyrolysis mechanism 4, and an internal heating mechanism 6 provided on the spiral conveying pyrolysis mechanism 4; The spiral conveying pyrolysis mechanism 4 includes a feeding section integrated shell 41 fixedly connected to the mounting bracket 1, a straight section integrated shell 42 detachably connected to the feeding section integrated shell 41, and a spiral conveying assembly 43 movably connected to the straight section integrated shell 42, the other end of the spiral conveying assembly 43 passes through the feeding section integrated shell 41 and is connected to the output end of the transmission mechanism 3, and the output end of the power drive mechanism 2 is connected to the input end of the transmission mechanism 3; The spiral conveying assembly 43 includes a hollow rotating shaft 4301 and a hollow spiral blade 4302 disposed on the hollow rotating shaft 4301. The inner space of the hollow rotating shaft 4301 is connected to the inner space of the hollow spiral blade 4302. The internal heating mechanism 6 is disposed on the hollow rotating shaft 4301. The internal heating mechanism 6 includes a circumferential air supply component provided at one end of the hollow rotating shaft 4301 and a circumferential exhaust component provided at the other end of the hollow rotating shaft 4301. The circumferential air supply component is used to input a set amount of smoke into the hollow rotating shaft 4301 and adjust the internal pressure of the hollow rotating shaft 4301 and the hollow spiral blade 4302. The circumferential exhaust component is used to discharge the smoke in the hollow rotating shaft 4301 and adjust the internal pressure of the hollow rotating shaft 4301 and the hollow spiral blade 4302. The hollow spiral blade 4302 is connected to a plurality of solidification and crushing mechanisms 7, and the plurality of solidification and crushing mechanisms 7 are evenly connected to the hollow spiral blade 4302. The solidification and crushing mechanism 7 includes a conical telescopic assembly connected to the hollow spiral blade 4302 and a pneumatic vibration assembly arranged between the conical telescopic assembly and the hollow spiral blade 4302. The internal space of the conical telescopic assembly is connected to the internal space of the hollow spiral blade 4302. When flowing gas is generated in the internal space of the hollow spiral blade 4302 and the internal space of the conical telescopic assembly, the pneumatic vibration assembly is driven by the flowing gas to rotate at a set speed and strike the conical telescopic assembly.

[0020] It should be noted that, after the fly ash is washed by the fly ash washing unit, it enters the filter press unit for filter pressing and dehydration treatment, and the dehydrated water is subjected to subsequent water treatment processes, such as evaporation and salt production, and the water vapor is condensed and then returned to the fly ash washing unit for reuse, and the fly ash after filter pressing and dehydration enters the feeding section integrated shell 41, and falls into the sealed conveying space formed between the feeding section integrated shell 41, the straight section integrated shell 42 and the screw conveying assembly 43. Initially, there is no high-temperature flue gas in the external heating mechanism 5, and the power drive mechanism 2 drives the screw conveying assembly 43 to rotate through the transmission mechanism 3, and conveys the dehydrated fly ash to the high-temperature pyrolysis unit, and the high-temperature pyrolysis The unit uses natural gas combustion to supply heat, so that the fly ash is pyrolyzed to produce dioxins and organic substances, which are then introduced into the combustion equipment for combustion. The high-temperature flue gas generated after combustion is introduced into the external heating mechanism 5 and the internal heating mechanism 6, so that the fly ash entering the sealed conveying space formed between the feeding section integrated shell 41, the straight section integrated shell 42 and the spiral conveying assembly 43 also begins to pyrolyze, so as to reduce the energy consumption of the subsequent high-temperature pyrolysis unit. The high-temperature flue gas is introduced into the external heating mechanism 5 in a continuous flow manner, and into the internal heating mechanism 6 in an intermittent manner. Specifically, the high-temperature flue gas is introduced from the circular air supply assembly. At this time, the circular The peripheral exhaust assembly is in a closed state, and the high-temperature flue gas enters the hollow rotating shaft 4301 and the hollow spiral blades 4302 and then enters the conical telescopic assembly, so that the conical telescopic assembly enters an extended state under the action of pressure and drills into the moving fly ash to increase the contact area between the fly ash and the heat and improve the fly ash pyrolysis efficiency. At the same time, the fly ash slightly solidified on the surface of the hollow spiral blades 4302 can also be crushed and pushed down, thereby effectively preventing the fly ash from solidifying on the hollow spiral blades 4302 and causing the heat energy to be isolated. When the high-temperature flue gas enters the conical telescopic assembly, the pneumatic vibration assembly is driven by the airflow to knock the conical telescopic assembly. The impact produces vibration, and in conjunction with its extension process, the damaged slightly solidified fly ash on the surface of the hollow spiral blade 4302 can be effectively vibrated off. When the set pressure is reached, the circular exhaust component is opened to achieve continuous circulation of high-temperature flue gas. After the set time, the circular air supply component is closed to extract the residual high-temperature flue gas, forming a negative pressure, so that the conical telescopic component retracts, and the pneumatic vibration component vibrates, which can effectively remove the slightly solidified fly ash again. This cycle can effectively improve the pyrolysis efficiency. The fly ash after high-temperature pyrolysis is used for subsequent utilization, such as preparing building materials, and the high-temperature flue gas is treated after the waste heat is utilized and discharged after meeting the standards.

[0021] like Figure 4 As shown, the transmission mechanism 3 includes a protective housing 301 connected to the mounting bracket 1, a first sprocket 302 connected to the output shaft end of the power drive mechanism 2, a second sprocket 303 connected to the other end of the hollow rotating shaft 4301, and a chain 304 connected between the first sprocket 302 and the second sprocket 303; The straight-section integrated shell 42 includes a straight-section shell 4201 connected to the feeding-section integrated shell 41 , a feed port 4202 and an exhaust pipe 4203 provided on the straight-section shell 4201 , and the feed port 4202 is located below the exhaust pipe 4203 .

[0022] It should be noted that, as mentioned above, when the power drive mechanism 2 drives the screw conveying assembly 43 to rotate through the transmission mechanism 3, the power drive mechanism 2 drives the first sprocket 302 to rotate. When the first sprocket 302 rotates, it drives the second sprocket 303 to rotate through the chain 304. When the second sprocket 303 rotates, it drives the hollow rotating shaft 4301 connected thereto to rotate in the same direction and at the same angle. After the hollow rotating shaft 4301 rotates, the fly ash that falls into the sealed conveying space formed between the feeding section integrated shell 41, the straight section integrated shell 42 and the screw conveying assembly 43 is driven to move along the length direction of the straight shell 4201 until the fly ash moves to the discharge port 4202 and falls into the high-temperature pyrolysis unit. In this process, dioxins and other substances produced by pyrolysis are discharged from the exhaust pipe 4203 into the combustion equipment for combustion, and the flue gas generated after combustion can be passed into the external heating mechanism 5 and the internal heating mechanism 6 for waste heat utilization.

[0023] like Figure 4-Figure 6 As shown, the circumferential air supply assembly includes a first air guide ring 601 fixedly connected to the straight cylindrical shell 4201, a first annular chamber 602 arranged inside the first air guide ring 601, a second smoke inlet pipe 603 fixedly connected to the first air guide ring 601, a first air guide cavity 604 arranged on the hollow rotating shaft body 4301 and a first solenoid valve connected to the second smoke exhaust pipe 607, the first annular chamber 602 is connected to the internal space of the hollow rotating shaft body 4301 through the first air guide cavity 604, and the second smoke inlet pipe 603 is connected to the first annular chamber 602.

[0024] It should be noted that, as mentioned above, when the high-temperature flue gas is introduced into the circular air supply assembly, it enters the first annular chamber 602 in the first air guide ring 601 from the second flue gas inlet pipe 603. At this time, the hollow rotating shaft body 4301 is in a rotating state, but it does not affect the high-temperature flue gas flowing through the first annular chamber 602 and the first air guide cavity 604 in sequence and then entering the hollow rotating shaft body 4301. The first solenoid valve can control the on and off state of the second flue gas inlet pipe 603.

[0025] like Figure 4 , Figure 7-Figure 8As shown, the circumferential exhaust assembly includes a second air guide ring 605 fixedly connected to the protective shell 301, a second annular chamber 606 arranged inside the second air guide ring 605, a second smoke exhaust pipe 607 fixedly connected to the second air guide ring 605, a second air guide cavity 608 arranged on the hollow rotating shaft body 4301, and a second solenoid valve connected to the second smoke exhaust pipe 607, the second annular chamber 606 is connected to the internal space of the hollow rotating shaft body 4301 through the second air guide cavity 608, the second smoke exhaust pipe 607 is connected to the second annular chamber 606, a plurality of first air guide holes 4303 are provided on the hollow rotating shaft body 4301, and the plurality of first air guide holes 4303 are equidistantly distributed along the spiral trajectory of the hollow spiral blade 4302, and the internal space of the hollow rotating shaft body 4301 is connected to the internal space of the hollow spiral blade 4302 through the plurality of first air guide holes 4303.

[0026] It should be noted that, as mentioned above, after the high-temperature flue gas enters the hollow rotating shaft 4301, it flows through the first air guide hole 4303 and the internal space of the hollow spiral blade 4302 in sequence. As the high-temperature flue gas continues to enter, it gradually accumulates in the hollow rotating shaft 4301, the first air guide hole 4303, and the hollow spiral blade 4302, and generates a set pressure.

[0027] like Figure 4 As shown, the external heating mechanism 5 includes a first smoke inlet pipe 502 and a first smoke exhaust pipe 503 covered with a hollow insulation shell 501, connected to the hollow insulation shell 501, the hollow insulation shell 501 covers the outside of the feeding section integrated shell 41 and the straight section integrated shell 42, the first smoke inlet pipe 502 is located near the discharge port 4202, and the first smoke exhaust pipe 503 is located near the feeding section integrated shell 41.

[0028] It should be noted that the high-temperature flue gas is introduced from the first flue gas inlet pipe 502, flows through the hollow insulation shell 501 and is discharged from the first flue gas exhaust pipe 503. During this process, the high-temperature flue gas can heat the feeding section integrated shell 41 and the straight-cylinder section integrated shell 42. The heat is transferred through the feeding section integrated shell 41 and the straight-cylinder section integrated shell 42 and then dissipated to the sealed conveying space formed between the feeding section integrated shell 41, the straight-cylinder section integrated shell 42 and the spiral conveying assembly 43, and the fly ash is thermally decomposed.

[0029] like Figure 9-11 As shown, the conical telescopic assembly includes a conical telescopic casing 701 fixedly connected to the hollow spiral blade 4302 and a multi-section telescopic rod 702 connected between the conical telescopic casing 701 and the hollow spiral blade 4302, and the multi-section telescopic rod 702 is located on the central axis of the conical telescopic casing 701; The hollow spiral blade 4302 is provided with a plurality of second air guide holes 4304 and third air guide holes 4305. The inner space of the hollow spiral blade 4302 is connected to the inner space of the correspondingly arranged conical telescopic casing 701 and the multi-section telescopic rod 702 through the second air guide holes 4304 and the third air guide holes 4305 respectively. The pneumatic vibration assembly includes an adapting sealing plate 703 fixedly connected to the inner wall of the second air guide hole 4304, a fifth air guide hole 705 provided on the adapting sealing plate 703, a rotating ring 706 movably connected to the inner wall of the fifth air guide hole 705, a first connecting rod 707 fixedly connected to the rotating ring 706, a rotating rod 708 fixedly connected to the first connecting rod 707, a fan blade 709 connected to the rotating rod 708 and a second connecting rod 710, a spring 711 connected to the second connecting rod 710, and a sphere 712 connected to the spring 711, the fan blade 709 is in the fifth air guide hole 705, and the sum of the lengths of the second connecting rod 710 and the spring 711 is greater than the distance between the rotating rod 708 and the multi-section telescopic rod 702; The adapter sealing plate 703 is provided with a plurality of fourth air guide holes 704 , and a plastic sealing sheet 713 is connected to the end surface of the adapter sealing plate 703 close to the inside of the conical telescopic sleeve 701 , the plastic sealing sheet 713 covers the plurality of fourth air guide holes 704 , and only one end of the plastic sealing sheet 713 is fixedly connected to the adapter sealing plate 703 .

[0030] It should be noted that, as mentioned above, with the accumulation of high-temperature flue gas, the high-temperature flue gas flows from the hollow spiral blade 4302 to the second air guide hole 4304 and the third air guide hole 4305, and the high-temperature flue gas can enter the conical sealed space formed between the conical telescopic shell 701 and the hollow spiral blade 4302 and the inside of the multi-section telescopic rod 702. As the amount of gas entering increases, the air pressure gradually increases, and pushes the conical telescopic shell 701 and the multi-section telescopic rod 702 to extend. In the process of gas flowing into the fifth air guide hole 705, the fan blade 709 is driven to rotate, and the rotating rod 708, the second connecting rod 710, the spring 711, and the ball 712 are driven to rotate in the same direction and at the same angle. During the rotation process, the ball 712 will continuously hit the multi-section telescopic rod 702, causing the multi-section telescopic rod 702 to vibrate, and transmit the vibration to the conical telescopic rod 702. The conical telescopic shell 701 and the hollow spiral blades 4302 are used to vibrate and remove the crushed micro-solidified fly ash. In the process of gas flowing into the conical telescopic shell 701, the plastic sealing sheet 713 is pushed open by the airflow, so that the gas can quickly enter. When the gas is extracted, the plastic sealing sheet 713 is pressed and tightly covered by the airflow on the fourth air guide hole 704, so that the gas in the conical telescopic shell 701 can only flow out from the fifth air guide hole 705, so that the air flow rate becomes faster, which can drive the fan blades 709 to rotate faster and achieve higher frequency vibration to cooperate with the retraction process of the conical telescopic shell 701. The micro-solidified fly ash outside the conical telescopic shell 701 can be effectively vibrated away, effectively reducing the influence of the micro-solidified fly ash on the retraction of the conical telescopic shell 701, and achieving a more efficient vibration removal effect.

[0031] The present embodiment is described above, but the present embodiment is not limited to the above-mentioned specific implementation manner. The above-mentioned specific implementation manner is merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, which are all within the protection of the present embodiment.
