Description

Technical Field

[0001] This invention relates to the field of industrial solid waste resource recycling, specifically to an industrial solid waste resource recycling device. Background Technology

[0002] In recent years, with the promotion of municipal solid waste incineration power generation technology, more and more waste-to-energy plants have been put into operation, completely solving the problems of municipal solid waste treatment and environmental pollution. Incineration greatly reduces the volume of waste, completely destroys harmful substances in the waste, and recovers and utilizes the waste heat generated during incineration. However, the by-products generated during the incineration process, such as slag, including the incineration residue remaining on the grate and particles falling from the grate, are increasingly attracting attention due to their abundant resources, large output, and certain environmental pollution. Many experts and scholars have conducted in-depth research on their resource utilization. Existing research and engineering practice have proven that the resource utilization of slag is feasible. Currently, industrial solid waste brick making uses incineration slag as the main raw material. After pretreatment of the slag (removal of waste metal and raw materials), cement, curing agents, activators (or pigments), and other materials are added in a certain proportion, and then the bricks are pressed into shape by a brick-making machine.

[0003] However, since the slag contains a certain amount of Fe, non-ferrous metals, and unburned waste, direct use may affect the structural strength and durability of the bricks. In addition, the presence of these substances cannot meet the technical requirements for resource utilization. Therefore, before the slag is utilized for resource utilization, it must be sorted and pretreated to recycle waste metals such as Fe, Cu, and Al, separate and collect unburned waste, and recycle it.

[0004] For example, application number CN202510652586.8 provides a device and method for the resource utilization of municipal solid waste incineration slag. It can remove metals that can be magnetically adsorbed from the slag. However, other non-ferrous metals that cannot be magnetically adsorbed require additional treatment methods. In the prior art, eddy current separators are generally used, but their separation effect is limited. In the later brick making process, additional catalysts to prevent aluminum reaction are required, or chemical reactions are used to demetallize and passivate / stabilize them. Existing chemical reactions are generally carried out in a reactor, which requires a high-temperature medium. Using hot water will consume a lot of water resources and electricity, and will also generate a lot of wastewater, which is not worthwhile. In addition, the clogging problem of the reactor and the waste gas problem after the reaction greatly increase the cost of passivating aluminum. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an industrial solid waste resource recycling device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an industrial solid waste resource recycling device, including a vessel body, and further including a high-temperature steam reaction component and a steam turbulence unloading component installed inside and below the vessel body; it also includes a dust suppression component and a gas recovery component installed inside and above the vessel body; industrial solid waste brick-making aggregate is fed in from above the vessel body; The high-temperature steam reaction assembly includes a stirring mechanism and a wall scraping mechanism. The stirring mechanism is heated by steam to stir the mixed aggregate at the bottom of the vessel. The wall scraping mechanism is used to treat the aggregate adhering to the inner wall of the vessel. The wall scraping mechanism can release steam and uniformly mix it into the aggregate to enhance the reaction between the high temperature and aluminum powder, and also to reduce the adhesion of the aggregate to the stirring.

[0007] Preferably, the high-temperature steam reaction assembly further includes a central shaft, which is a hollow structure. A steam release assembly is installed at the bottom of the vessel. The central shaft is connected to and rotatably connected to the steam release assembly at the bottom. The interior of the central shaft is used to transmit steam from the steam release assembly. It also includes a connecting frame and a horizontal tube. The connecting frame is fixed to the central axis, and the horizontal tube is fixed to the central axis, and the two are connected to each other. The other end of the connecting frame is used to connect to the wall scraping mechanism, and the other end of the horizontal pipe is connected to the wall scraping mechanism and supplies steam to the wall scraping mechanism. The stirring mechanism is fixed to the lower end of the central shaft and is offset from the wall scraping mechanism. The stirring mechanism is internally connected to the central shaft.

[0008] Preferably, the scraping mechanism includes a scraper, which is fixed to a connecting frame. The scraper has a hollow interior structure. The scraper has matrix-distributed air holes on the side facing the inner wall of the vessel and on the front and rear sides. The air holes are connected to the hollow interior structure of the scraper. The hollow interior structure of the scraper is connected to a horizontal pipe. When the horizontal pipe supplies high-temperature and high-pressure steam to the interior of the scraper, the steam can be ejected from the air holes and act on the aggregate.

[0009] Preferably, the stirring mechanism includes a stirring blade, the interior of which is hollow and made of copper, and its hollow interior is connected to the interior of the central shaft.

[0010] Preferably, the steam tumbling unloading assembly includes a conical hood with its opening facing upwards. The conical hood is fixedly installed at the bottom of the vessel body, with its center corresponding to the bottom outlet of the vessel body. There is a tumbling area between its side wall and the inner wall of the vessel body. The lower end of the scraper is located in the tumbling area. Steam acts on the tumbling area to cause the aggregate to tumble into the conical hood to prevent clogging of the discharge in the later stage. It also includes a pneumatic rod, which is installed in the lower outlet of the vessel body. A sealing plug is installed at the output end of the pneumatic rod. Steam acts on the pneumatic rod to move the sealing plug to the uppermost position and seal the outlet of the vessel body. When the pressure is released, the sealing plug moves down and opens the outlet at the bottom of the vessel body.

[0011] Preferably, the dust suppression assembly is provided in two sets. The dust suppression assembly includes a water spray pipe, an inlet is installed on one side of the upper end of the vessel body, and atomizing nozzles are installed at the end and bottom of the water spray pipe. The atomizing nozzles are respectively horizontally corresponding to the feeding area of ​​the inlet and facing the interior of the corresponding vessel body.

[0012] Preferably, a steam generator is also installed above the vessel body, with water preheating on one side and preheating water released and heated on the other side to generate steam and supply high-temperature and high-pressure steam to the steam release component; A water tank is also installed above the vessel body to supply high-pressure water to the spray pipe and to supply water to the steam generator.

[0013] Preferably, the gas recovery assembly includes a gas collection pipe connected to a steam generator to transfer waste steam to high-temperature water, and a waste gas pipe is also installed at the upper end of the steam generator.

[0014] Preferably, a power component is also installed above the vessel body to transmit rotational power to the central shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This industrial solid waste resource recycling device, by setting up a high-temperature steam reaction component, can mix high-temperature steam into the aggregate when mixing industrial solid waste to make bricks, which is used to heat the aggregate. The water vapor of the steam can react with the aluminum powder in the aggregate after reaching high temperature, and stabilize the aluminum. This avoids the problem of low structural strength and easy cracking of bricks due to the presence of aluminum powder when molding bricks later.

[0016] 2. This industrial solid waste resource recycling device, by setting up a gas recovery component, allows the waste gas generated after the industrial solid waste aggregate reacts at high temperature to first pass through a hot water bath. Some of the ammonia and hydrogen in the gas can be dissolved in the water, and impurities can also be washed away. The remaining gas can then be recycled, significantly reducing costs. Thus, when treating industrial solid waste, it can effectively avoid waste gas pollution and can convert harmful substances into useful substances.

[0017] 3. This industrial solid waste resource recycling device is equipped with a steam tumbling unloading component. The steam can make the aggregate mix more evenly by tumbling the material. When adding catalysts and cement in the reactor, it can also be stirred more evenly. Compared with using only a mixer, the gas mixing method is more efficient, and the tumbling can make the material discharge smoother and greatly reduce the probability of blockage.

[0018] 4. This industrial solid waste recycling device is equipped with a wall scraping mechanism, which can prevent aggregate adhesion during wall scraping, and the steam sprayed out with the scraper can also avoid the problem of sticking.

[0019] 5. This industrial solid waste recycling device, by setting up dust reduction components, can significantly reduce dust volatilization during material feeding, improving the workshop environment and making it more environmentally friendly. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0024] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0026] like Figure 1-9 As shown, an industrial solid waste resource recycling device includes a vessel body 1, a high-temperature steam reaction assembly 2 and a steam tumbling unloading assembly 3 installed inside the lower part of the vessel body 1; a dust suppression assembly 4 and a gas recovery assembly 5 installed inside the upper part of the vessel body 1; industrial solid waste brick-making aggregate is fed in from the top of the vessel body 1. The high-temperature steam reaction assembly 2 includes a stirring mechanism 201 and a wall scraping mechanism 202. The stirring mechanism 201 is heated by steam to stir the mixed aggregate at the bottom of the vessel body 1. The wall scraping mechanism 202 is used to treat the aggregate adhering to the inner wall of the vessel body 1. The wall scraping mechanism 202 can release steam and uniformly mix it into the aggregate to enhance the reaction between the high temperature and aluminum powder, and also to reduce the adhesion of the aggregate to the stirring.

[0027] When using aluminum-containing industrial waste (especially waste containing metallic aluminum powder, such as secondary aluminum ash and waste aluminum slag) as aggregate for building bricks, removing or stabilizing the aluminum powder is a critical safety pretreatment step. Improper handling can lead to serious problems with residual aluminum powder. Metallic aluminum (especially fine powder) reacts in alkaline environments (such as cement hydration environments) to produce hydrogen gas, causing blistering, expansion, and cracking inside the brick, severely affecting its strength and durability. Residual aluminum nitride (AlN) reacts with water to produce ammonia gas, similarly causing porosity and odor.

[0028] Unlike existing technologies, this application includes a high-temperature steam reaction component 2, which uses high-temperature and high-pressure steam to react with aluminum powder in the aggregate. This saves a significant amount of water resources, eliminates the need to heat large amounts of water, reduces power consumption, and produces less wastewater after the reaction. This eliminates the need for additional wastewater treatment lines, and the reuse of waste materials for brick making is more energy-efficient and environmentally friendly.

[0029] Traditionally, feeding materials into a reactor involves opening the top of the reactor and directly feeding aggregates via a conveyor belt. However, during the feeding process, since the aggregates have already been ground into powder, a large amount of dust is generated with each feeding, resulting in dust covering the workshop floor and the area around the reactor. This has a significant impact on the workshop environment and seriously affects the health of workers, which is detrimental to environmentally friendly production. By installing the dust suppression component 4, the water mist mixed in with the fed aggregates can be agglomerated, which both adds water for the reaction and reduces dust generation.

[0030] In an optional embodiment, the high-temperature steam reaction assembly 2 further includes a central shaft 203, which is a hollow structure. A steam release assembly 204 is installed at the bottom of the vessel body 1. The central shaft 203 is connected to and rotatably connected to the steam release assembly 204 at the bottom. The interior of the central shaft 203 is used to transmit steam from the steam release assembly 204. It also includes a connecting frame 205 and a horizontal tube 206. The connecting frame 205 is fixed to the central shaft 203, and the horizontal tube 206 is fixed to the central shaft 203, and the two are connected to each other. The other end of the connecting frame 205 is used to connect to the wall scraping mechanism 202, and the other end of the horizontal pipe 206 is connected to the wall scraping mechanism 202 and supplies steam to the wall scraping mechanism 202; The stirring mechanism 201 is fixed to the lower end of the central shaft 203 and is offset from the wall scraping mechanism 202. The stirring mechanism 201 is internally connected to the central shaft 203.

[0031] In this embodiment, the central shaft 203 is a pipe, the steam release assembly 204 has a hollow cavity inside, and the central shaft 203 is connected to it with a bearing and a mechanical seal, which can realize relative rotation between the two without affecting the transfer of steam in the steam release assembly 204 to the central shaft 203.

[0032] The connecting frame 205 is a steel structure frame with a galvanized coating. The connecting frame 205 serves to reinforce the connection and maintain the power transmission without loosening under high torque and long-term stirring conditions.

[0033] The upper end of the central shaft 203 is equipped with a power connection shaft, which is also made of reinforced steel plate welding. Instead of using a single cylindrical shaft, it adopts the form of longitudinal welding of steel plates in a circumferential array, which can enhance the resistance to torsional load.

[0034] In an optional embodiment, the scraping mechanism 202 includes a scraper 2021, which is fixed to the connecting frame 205. The scraper 2021 has a hollow structure inside. The scraper 2021 has matrix-distributed air holes 2022 on the side facing the inner wall of the vessel body 1 and on the front and rear sides. The air holes 2022 are connected to the hollow structure inside the scraper 2021. The hollow structure of the scraper 2021 is connected to the horizontal pipe 206. When the horizontal pipe 206 supplies high-temperature and high-pressure steam to the interior of the scraper 2021, the steam can be ejected from the air holes 2022 and act on the aggregate.

[0035] In this embodiment, the shape of the scraper 2021 is matched with the structure of the vessel body 1. In addition to bolts, pins and other fasteners for stable connection, a compression spring, as in the prior art, is also provided at the connection position between the scraper 2021 and the connecting frame 205. This allows the scraper 2021 to have a micro-movement space, which keeps the scraper 2021 close to the vessel body 1 and reduces the hard friction between the two.

[0036] When mixing aggregate, the air holes 2022 on the scraper 2021 need to be kept in a state of steam spraying out to prevent aggregate from clogging the air holes 2022. When cleaning the vessel body 1, the steam release component 204 can also be connected to the high-pressure water circuit. The water flow can flush out the blocked air holes 2022 and can also be used to wash the vessel body 1.

[0037] In addition, the high-temperature and high-pressure steam sprayed during mixing can also prevent the aggregate from sticking to the scraper 2021.

[0038] In an optional embodiment, the stirring mechanism 201 includes a stirring blade 2011, the interior of which is hollow and made of copper, and its hollow interior is connected to the interior of the central shaft 203.

[0039] In this embodiment, the stirring blade 2011 does not have the ability to exhaust steam, but the copper structure of the stirring blade 2011 can transfer heat from the central shaft 203, so that the stirring blade 2011 has a certain amount of heat, which can further enhance the transfer of temperature to the aggregate during stirring.

[0040] In an optional embodiment, the steam tumbling discharge assembly 3 includes a conical shroud 301 with its opening facing upwards. The conical shroud 301 is fixedly installed at the bottom of the vessel body 1, with its center corresponding to the bottom outlet of the vessel body 1. There is a tumbling area 302 between its side wall and the inner wall of the vessel body 1. The lower end of the scraper 2021 is located in the tumbling area 302. Steam acts on the tumbling area 302 to cause the aggregate to tumble into the conical shroud 301 to prevent clogging of the discharge in the later stage. It also includes a pneumatic rod 303, which is installed in the lower outlet of the vessel body 1. A sealing plug 304 is installed at the output end of the pneumatic rod 303. Steam acts on the pneumatic rod 303 to move the sealing plug 304 to the uppermost position and seal the outlet of the vessel body 1. When the pressure is released, the sealing plug 304 moves down and opens the outlet at the bottom of the vessel body 1.

[0041] In this embodiment, the lower end of the scraper 2021 does not contact the outer wall of the conical cover 301, which can avoid friction between the two. However, the aggregate in the turning area 302 will still be turned into the inside of the conical cover 301 due to the stirring of the scraper 2021 and the impact of steam. Finally, when the material is discharged, only a very small amount of aggregate will remain in the turning area 302, which will not affect the overall aggregate conveying.

[0042] The pneumatic rod 303 is used to automatically open and close the bottom of the vessel body 1 using steam pressure, and can also be used with additional hydraulic or pneumatic power.

[0043] In an optional embodiment, the dust suppression assembly 4 is provided in two sets. The dust suppression assembly 4 includes a water spray pipe 401. A feed inlet 402 is installed on one side of the upper end of the vessel body 1. Atomizing nozzles 403 are installed at the end and bottom of the water spray pipe 401. The atomizing nozzles 403 are respectively horizontally corresponding to the feeding area of ​​the feed inlet 402 and facing the interior of the corresponding vessel body 1.

[0044] In this embodiment, the water spray pipe 401 is connected to a high-pressure pump, which can supply high-pressure water to the atomizing nozzle 403. After the water flows through the atomizing nozzle 403, it will diffuse into small water mist particles. When feeding, the dust that rises can combine with the small water mist particles and agglomerate and settle, preventing more dust from flying outside the vessel body 1. The water mist diffused by the atomizing nozzle 403 can treat the dust in the feeding area and can also treat the dust in the vessel body 1 again.

[0045] In an optional embodiment, a steam generator 10 is also installed above the vessel body 1, with water preheating on one side and preheating water released and heated on the other side to generate steam and supply high-temperature and high-pressure steam to the steam release assembly 204. A water tank 6 is also installed above the vessel body 1, which is used to supply high-pressure water to the water spray pipe 401 and to supply water to the steam generator box 10.

[0046] In this embodiment, the steam generator 10 is used to heat water and generate high-temperature and high-pressure steam. It is separate from the water tank 6 and can generate steam continuously, which is fast and saves a lot of heat.

[0047] In an optional embodiment, the gas recovery assembly 5 includes a gas collection pipe 7 connected to a steam generator 10, which transfers waste steam to high-temperature water. The upper end of the steam generator 10 is also equipped with a waste gas pipe 8.

[0048] In this embodiment, after receiving steam and hydrogen and ammonia produced by the reaction, the gas collecting pipe 7 can be washed with water and then collected and processed again, which can reduce the pressure of subsequent processing.

[0049] In an optional embodiment, a power unit 9 is also installed above the vessel body 1 for transmitting rotational power to the central shaft 203.

[0050] In this embodiment, the power component 9 is used to connect the drive shaft to rotate the central shaft 203, which can provide a large mechanical torque.

[0051] In operation, the feeder first uses a screw pump to feed material into the vessel 1 from above. The material enters the vessel 1 through the feed inlet 402. After the solid waste aggregate is fed, the feed inlet 402 is sealed using a hydraulic seal. At this point, the aggregate containing aluminum powder accumulates at the bottom of the vessel 1. Steam is generated by the steam generator 10 and sent to the steam release assembly 204. The steam collects in the central shaft 203, which rotates under the drive of the power mechanism above. The rotation of the central shaft 203 drives the stirring mechanism 201 to stir the contents of the vessel 1. The aggregate is stirred, and the scraper mechanism 202 stirs and cleans the inner wall of the vessel 1. During the stirring process, the high-temperature and high-pressure steam inside the central shaft 203 is ejected through the air holes 2022 on the scraper 2021. The ejected steam is mixed with the aggregate, and because the ejected steam has high heat, it can cause water and aluminum to react at high temperature to produce aluminum hydroxide. Aluminum hydroxide is relatively stable and can be used as a filler mixed in the aggregate for brick making. The high-temperature steam also heats the stirring blade 2011, so that the mixing reaction is always carried out at a high temperature.

[0052] During the continuous stirring and steam reaction, excess gas is collected and discharged by the gas collecting pipe 7 above. The gas collecting pipe 7 sends the excess steam and the hydrogen, ammonia and other gases produced by the reaction back to the hot water. After the gas is washed, the gas discharged from the exhaust pipe 8 again needs to be collected and treated separately.

[0053] During unloading, the steam generated by the scraper 2021 at the bottom will agitate the aggregate and move it into the conical hood 301. Through continuous agitation and opening the bottom outlet, the mixed aggregate can be discharged quickly and without blockage.
