Description

Technical Field

[0001] This invention relates to the field of industrial solid waste treatment technology, specifically to a device for the efficient separation and harmless treatment of heavy metals in bulk industrial solid waste. Background Technology

[0002] The annual output of bulk industrial solid wastes such as coal gangue, fly ash, tailings (associated minerals), and smelting slag is enormous. These solid wastes generally contain heavy metal pollutants such as chromium, lead, cadmium, and mercury. If they are not efficiently separated and harmlessly disposed of, heavy metals can easily leach into the soil and water bodies with rainwater and natural weathering, causing serious ecological and environmental pollution and harm to human health. This is the core challenge of industrial environmental governance. Existing heavy metal treatment equipment for bulk industrial solid waste suffers from significant technical deficiencies: First, the pretreatment stage relies solely on mechanical crushing, which fails to break the dense encapsulation structure of solid waste particles, resulting in incomplete heavy metal dissociation and significantly increasing the difficulty of subsequent separation. Second, the heavy metal separation process is simplistic, relying only on magnetic separation or electrophoresis, which cannot simultaneously remove magnetic heavy metal particles and charged heavy metal ions, leading to low separation efficiency and poor sorting accuracy. Third, the lack of a deep purification stage means that residual heavy metal complexes and organic pollutants cannot be degraded, making it difficult for treated materials to meet environmental emission standards. Fourth, the solidification process uses a single physical solidification method, resulting in poor heavy metal stability and a high risk of secondary leaching pollution. Fifth, the equipment has a modular layout, requiring a large floor space, resulting in high material transfer losses, and hindering continuous, graded treatment with poor automation adaptability. Therefore, developing an integrated, multi-stage, highly efficient, and thoroughly harmless heavy metal treatment system for bulk industrial solid waste has become a pressing technical challenge for the industry. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency separation and harmless treatment equipment for heavy metals in bulk industrial solid waste, which has a small overall footprint, low material conveying loss, and significantly improved treatment efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency separation and harmless treatment device for heavy metals in bulk industrial solid waste includes a main support structure and, from top to bottom, a pretreatment dissociation mechanism, a magnetothermal electrophoresis synergistic treatment mechanism, a photocatalytic deep treatment mechanism, and a microbial synergistic solidification mechanism arranged in the main support structure. The main support structure includes a main support cylindrical shell arranged with its axis extending vertically; The pretreatment dissociation mechanism includes an ultrasonic air-dissociation cylinder located near the top of the main support cylinder with its opening facing upwards. The top of the main support cylinder is connected to multiple vertically extending ultrasonic vibration rods via an ultrasonic lifting mechanism. The ultrasonic cavitation separation cylinder is surrounded by a centrifugal vortex separation ring shell with an upward opening arranged coaxially with it; The ultrasonic cavitation separation cylinder is connected to the centrifugal cyclone separation ring shell through multiple transfer and delivery pipes; The magnetothermal electrophoresis co-processing mechanism includes a co-processing outer shell fixed inside the main support shell with its opening facing upwards, a vertically extending co-processing inner shell inside the co-processing outer shell, multiple electromagnetic induction coils at the bottom of the co-processing outer shell, multiple first electrophoresis electrodes embedded and fixed on the inner side wall of the co-processing outer shell, and multiple second electrophoresis electrodes embedded and fixed on the outer side wall of the co-processing inner shell. The top of the main support cylinder shell is equipped with multiple movable and liftable disintegration pipes via an external discharge lifting mechanism. These disintegration pipes are connected to the interior of the co-processing outer cylinder shell via remote pumping pipes. The photocatalytic deep processing mechanism includes a photocatalytic processing cylinder shell fixed inside the main support cylinder shell with its opening facing upward. The photocatalytic processing cylinder shell is provided with a photocatalytic spiral flow channel formed by a spiral flow channel partition, and multiple ultraviolet lamp tubes are provided in the photocatalytic spiral flow channel. The inner tube shell of the co-processing system is connected to one end of the outer side of the photocatalytic spiral flow channel via a screening output tube.

[0005] Preferably, the bottom of the ultrasonic cavitation decomposition cylinder is provided with multiple initial slurry input pipes that are connected to its interior, and the transfer and delivery pipe is located on the outside of the ultrasonic cavitation decomposition cylinder near the top. A remote delivery pump is installed on the remote pumping pipe; The outer shell of the co-processing unit is equipped with a waste slurry discharge pipe at the bottom near the outer edge, which is connected to the interior of the shell. The bottom center of the top photocatalytic treatment cylinder shell is equipped with a catalytic treatment output pipe that is connected to one end of the inner side of the photocatalytic spiral flow channel.

[0006] illustrate: Preferably, the spiral flow channel baffles are arranged spirally along the bottom plane inside the photocatalytic treatment cylinder shell, and a photocatalytic spiral flow channel is formed between two adjacent spiral flow channel baffles; Multiple light-emitting hollow plates are fixed along the flow direction in the photocatalytic spiral channel, and ultraviolet lamps are installed inside the light-emitting hollow plates.

[0007] Description: A closed-loop photocatalytic spiral flow channel is formed by the spiral flow channel baffle extending spirally along the bottom plane of the photocatalytic treatment cylinder shell. This can effectively extend the residence time of the photocatalytic reaction of industrial solid waste slurry and improve the sufficiency of pollutant degradation. The hollow plate of the light-emitting support has the dual functions of flow channel support and light source protection. The ultraviolet lamp tube is encapsulated inside the plate body, which can prevent the slurry from directly washing and eroding the ultraviolet lamp tube, extend the service life of the light source, and at the same time ensure that the ultraviolet light uniformly covers the entire area of ​​the photocatalytic spiral flow channel, maximizing the efficiency of photocatalytic reaction.

[0008] Preferably, the ultrasonic lifting mechanism includes an ultrasonic lifting fixed cylinder fixed to the top of the main support cylinder shell with the opening facing downward, an ultrasonic lifting support column slidably connected inside the ultrasonic lifting fixed cylinder, and an ultrasonic vibration rod fixed to the lower end of the ultrasonic lifting support column. The ultrasonic lifting fixed cylinder is equipped with an ultrasonic lifting drive rod for driving the ultrasonic lifting support column to move.

[0009] Description: The design adopts a sleeve-type vertical sliding fit. The ultrasonic lifting drive rod can precisely drive the ultrasonic lifting support column to move vertically back and forth along the ultrasonic lifting fixed cylinder, thereby flexibly adjusting the immersion depth of the ultrasonic vibration rod in the ultrasonic cavitation dissociation cylinder. It can adapt to industrial solid waste slurry conditions with different liquid levels and different processing volumes, ensuring that the ultrasonic cavitation force fully covers the slurry and improving the uniformity and thoroughness of heavy metal dissociation.

[0010] Preferably, the external discharge lifting mechanism includes an external discharge lifting support column fixed to the top of the main support cylinder shell and extending vertically, an external discharge lifting support slide rail extending vertically fixed to the side of the external discharge lifting support column, an external discharge lifting support slider slidably connected to the external discharge lifting support slide rail, and the lifting support slider being fixedly connected to the detached external discharge pipe. The top of the main support cylinder shell has multiple vertical through holes for external discharge. These holes are evenly distributed along the radial direction of the main support cylinder shell, and multiple detached external discharge pipes are inserted into each external discharge hole in a corresponding manner.

[0011] Description: The sliding rail and slider transmission structure enables precise lifting and lowering adjustment of the external discharge pipe, which can accurately control the material extraction depth of the external discharge pipe into the centrifugal cyclone separator ring shell, and directionally extract qualified slurry from the inner side after centrifugal stratification.

[0012] Preferably, the centrifugal cyclone separation ring shell is driven to rotate around the axis of the main support cylinder shell by a circumferential centrifugal drive mechanism provided on the inner wall of the main support cylinder shell. The circumferential centrifugal drive mechanism includes a centrifugal drive support ring fixed on the inner wall of the main support cylinder shell and coaxial with it. A centrifugal drive ring rail coaxial with it is fixed on the top of the centrifugal drive support ring ring. Multiple centrifugal drive sliders are slidably connected on the centrifugal drive ring rail. The centrifugal cyclone separation ring shell is fixed together on the top of the multiple centrifugal drive sliders.

[0013] Description: The device adopts a coaxial ring rail circumferential drive design. The centrifugal drive support ring provides stable load support for the overall rotating structure. The centrifugal drive slider moves at a uniform speed circumferentially along the centrifugal drive ring rail, driving the centrifugal cyclone separation ring shell to rotate stably on the same axis, generating a uniform and stable centrifugal force field. This achieves efficient solid-liquid separation and coarse impurity screening of industrial solid waste slurry, effectively avoiding the problem of uneven sorting caused by rotational eccentricity, and significantly improving the stability and reliability of equipment operation.

[0014] Preferably, a spiral scraper drive ring coaxial with the top of the co-processing inner tube shell is rotatably connected, and a spiral scraper that is spirally wound around the outside of the spiral scraper drive ring is fixed on the outside of the co-processing inner tube shell. Multiple scraper conveying holes that penetrate radially are opened on the outside of the co-processing inner tube shell near the top. The lower end of the inner tube shell of the co-processing extends downward through the bottom of the outer tube shell of the co-processing. A screening and storage box connected to the interior of the inner tube shell is fixed at the lower end of the inner tube shell. A screening conveyor is installed inside the screening and storage box, and a screening output pipe is installed at the output end of the screening conveyor.

[0015] Description: The rotating spiral scraper can continuously scrape and enrich the heavy metal slurry on the outer wall of the inner tube shell of the co-processing unit, avoiding material adhesion and accumulation that could cause channel blockage. The scraper conveying hole enables directional flow and transportation of industrial solid waste slurry. The screening and storage box and the screening conveyor complete the material buffering and quantitative transportation, ensuring that the heavy metal-rich industrial solid waste slurry is continuously and stably transported to the photocatalytic deep treatment unit.

[0016] Preferably, multiple segmented partitions are evenly distributed along the photocatalytic spiral channel. The segmented partitions are porous hollow structures that run through the flow direction of the photocatalytic spiral channel. The photocatalytic spiral channel is filled with multiple catalytic coated spheres, and the surface of the catalytic coated spheres is coated with a layer of titanium dioxide photocatalytic coating.

[0017] Explanation: The segmented baffle with a porous and hollow structure can effectively limit and intercept the catalytic coated spheres in the photocatalytic spiral flow channel, preventing the catalytic filler from being lost with the slurry, while not affecting the smooth flow of industrial solid waste slurry; the catalytic coated spheres with a titanium dioxide photocatalytic coating on their surface greatly increase the contact area of ​​the photocatalytic reaction, enhance the generation efficiency of strong oxidizing groups under ultraviolet light excitation, and can deeply degrade residual heavy metal ions and organic pollutants in the slurry.

[0018] Preferably, the microbial co-curing mechanism includes a co-curing receiving ring shell fixed at the bottom of the main support cylinder shell with the opening facing upward. Multiple radial partition plates extending radially are fixed inside the co-curing receiving ring shell, and a curing treatment chamber is formed between two adjacent radial partition plates. Multiple curing stirring drive shafts extending radially are rotatably connected to the outer wall of the co-curing containment ring. Multiple short stirring rods are provided on one end of the curing stirring drive shaft inside the co-curing containment ring. Multiple stirring drive housings are provided on the outer wall of the main support cylinder shell. Multiple curing stirring drive shafts extend one by one into each stirring drive housing. A stirring drive motor for driving the curing stirring drive shaft to rotate is provided in the stirring drive housing. The catalytic treatment output pipe is connected to a curing distribution box, which contains a curing distribution conveyor. The output end of the curing distribution conveyor is connected to each curing treatment chamber through a curing distribution pump pipe.

[0019] Description: The co-curing containment ring is divided into multiple independent curing chambers by radial partition plates, which can realize batch parallel curing treatment of industrial solid waste slurry, improve the equipment's processing capacity, and drive the curing stirring drive shaft and stirring rod to rotate synchronously, so as to achieve uniform mixing of industrial solid waste slurry, auxiliary materials and microbial agents, and enhance the microbial adsorption and chelation curing effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects: 1. This invention uses the main supporting cylinder shell as the core load-bearing structure, and integrates a pretreatment dissociation mechanism, a magnetothermal electrophoresis co-processing mechanism, a photocatalytic deep processing mechanism, and a microbial co-solidification mechanism from top to bottom. It realizes the integrated continuous processing of heavy metal dissociation, separation, deep degradation, and stable solidification of bulk industrial solid waste slurry. It does not require separate equipment for transportation, has a small footprint, low material transportation loss, and significantly improves overall processing efficiency. 2. The pretreatment dissociation mechanism of this invention adopts ultrasonic cavitation technology with ultrasonic vibration rod and ultrasonic cavitation dissociation cylinder to efficiently break the dense encapsulation structure of solid waste particles and achieve full dissociation of heavy metals; the centrifugal cyclone separation ring shell and the circumferential centrifugal drive mechanism generate a uniform centrifugal force field to complete the primary solid-liquid separation of slurry and the precise screening of coarse impurities. 3. The magnetothermal electrophoresis synergistic processing mechanism of the present invention generates an alternating magnetic field through an electromagnetic induction coil to achieve efficient magnetic separation of magnetic heavy metal particles. The first electrophoresis electrode and the second electrophoresis electrode form a directional electric field to achieve directional electrophoretic migration and enrichment of charged heavy metal ions. The magneto-electric synergistic effect is used to remove multiple forms of heavy metals simultaneously. 4. The photocatalytic deep treatment mechanism of this invention extends the reaction path of the slurry through a photocatalytic spiral flow channel. The ultraviolet lamp excites the titanium dioxide photocatalytic coating on the surface of the catalytic coated spheres to generate strong oxidizing groups, which deeply degrades residual heavy metal ions and organic complex pollutants. The segmented partition helps to limit the catalytic packing and ensures smooth material flow. 5. The microbial co-solidification mechanism of this invention adopts a multi-chamber parallel solidification design. The stirring drive component realizes the uniform mixing of mineral slurry, auxiliary materials and microbial agents. It relies on the adsorption and chelation of microorganisms to achieve stable solidification of heavy metals. The heavy metal leaching rate of the solidified product meets the standards, completely eliminating secondary pollution and realizing the harmless and compliant disposal of bulk industrial solid waste.

[0021] 6. The present invention features a modular design for each functional mechanism, standardized configuration of drive components, and fully enclosed processing, with no dust or waste liquid leakage. It can be adapted to the heavy metal treatment needs of various types of bulk industrial solid waste and has a wide range of applications. Attached Figure Description

[0031] Example 5: Based on Example 4, such as Figure 3As shown, a spiral scraper drive ring 35 coaxially connected to the top of the co-processing inner tube shell 32 is rotatably connected to it. A spiral scraper 351 spirally wound around the outside of the spiral scraper drive ring 35 is fixed on the outside of the co-processing inner tube shell 32. Multiple scraper conveying holes 352 are provided on the outside of the co-processing inner tube shell 32 near the top.

Figure 5 As shown, the photocatalytic spiral channel 400 is filled with multiple catalytic coated microspheres 44, and the surface of the catalytic coated microspheres 44 is coated with a layer of titanium dioxide photocatalytic coating.

[0033] In practical applications, the present invention crushes the industrial solid waste to be treated into fine powder with a particle size of 50μm, and adds water to form an industrial solid waste slurry with a moisture content of 40%. Industrial solid waste slurry flows from top to bottom through the pretreatment dissociation unit 20, the magnetothermal electrophoresis co-treatment unit 30, the photocatalytic deep treatment unit 40, and the microbial co-solidification unit 50 for treatment, completing the dissociation, separation, deep degradation and final solidification of heavy metals; Pretreatment dissociation: Using an existing slurry pump, industrial solid waste slurry is fed into the ultrasonic cavitation dissociation cylinder 21 through the initial slurry input pipe 211. Then, the inner rod of the ultrasonic lifting drive rod 613 extends and drives the ultrasonic lifting support column 612 to move down along the ultrasonic lifting fixed cylinder 611. The ultrasonic lifting support column 612 then drives the ultrasonic vibration rod 22 to move down and extend into the industrial solid waste slurry in the ultrasonic cavitation dissociation cylinder 21. The ultrasonic vibration rod 22 is activated, and the ultrasonic cavitation effect breaks the solid waste particle encapsulation structure, so that the heavy metals are fully dissociated. After dissociation, the industrial solid waste slurry flows into the coaxially arranged centrifugal cyclone separator ring shell 23 through the transfer and conveying pipe 212; the centrifugal drive mechanism 63 drives the centrifugal cyclone separator ring shell 23 to rotate, and the centrifugal drive slider 633 moves along the centrifugal drive ring track 632, thereby driving the centrifugal cyclone separator ring shell 23 to rotate at high speed, and the primary solid-liquid separation and impurity coarse screening of the industrial solid waste slurry are completed through centrifugal action. After separation, qualified industrial solid waste slurry will be concentrated in the area near the inner side of the centrifugal cyclone separator ring 23, while coarser particles and waste residue with greater density will be thrown to the outer side of the centrifugal cyclone separator ring 23 under the action of centrifugal force. Industrial solid waste slurry is extracted using the dissociation pipe 24 located near the inner region of the centrifugal cyclone separator ring 23. The external discharge lifting support slider 623 moves down along the external discharge lifting support slide rail 622, which can drive the dissociation pipe 24 to move down and extend into the centrifugal cyclone separator ring 23. The industrial solid waste slurry is extracted using the remote transfer pump 242 and transported to the co-processing outer shell 31 through the remote pumping pipe 241.

[0034] Magnetothermophoretic synergistic processing: After the industrial solid waste slurry enters the outer shell 31 of the co-processing, the electromagnetic induction coil 33 is turned on, and the electromagnetic induction coil 33 at the bottom generates an alternating magnetic field to magnetically separate the magnetic heavy metal particles. The first electrophoresis electrode 341 on the inner wall of the outer shell 31 and the second electrophoresis electrode 342 on the outer wall of the inner shell 32 are respectively connected to the positive and negative terminals of a DC power supply, forming an electric field along the radial direction of the outer shell 31. Through electrophoresis, charged heavy metal ions migrate in a directional manner, causing the charged heavy metal ions to migrate closer to the inner shell 32. The waste residue formed after separation is discharged through the waste slurry discharge pipe 311. The spiral scraper drive ring 35 drives the spiral scraper 351 to perform a scraping action, which pushes the heavy metal-enriched industrial solid waste slurry attached to the outer wall of the co-processing inner shell 32 into the interior of the co-processing inner shell 32 through the scraper conveying hole 352. The heavy metal-enriched industrial solid waste slurry then falls into the screening storage box 353. With the conveying action of the screening conveyor 354, the industrial solid waste slurry is transported to the photocatalytic spiral flow channel 400 through the screening output pipe 355.

[0035] Photocatalytic deep processing stage: Industrial solid waste slurry enters the photocatalytic spiral flow channel 400 inside the photocatalytic treatment cylinder shell 41, and flows from the outside to the inside, undergoing spiral slow flow transportation, which is beneficial to extend the treatment time. The built-in ultraviolet lamp 421 of the light-emitting support hollow plate 42 provides ultraviolet light, which activates the titanium dioxide photocatalytic coating on the surface of the catalytic coated spheres 44 in the flow channel, generating strong oxidizing groups to deeply degrade residual heavy metal ions and organic pollutants. The segmented partition 43 has a porous and hollow structure, which limits the catalytic coated balls 44 to prevent them from leaking out, while ensuring the smooth flow of industrial solid waste slurry. The deeply purified industrial solid waste slurry is discharged through the catalytic treatment output pipe 411 and enters the solidification distribution box 53.

[0036] Microbial co-solidification: The industrial solid waste slurry that enters the solidification distribution box 53 is evenly distributed by the solidification distribution conveyor 531 and then sent to each solidification treatment chamber 501 through the solidification distribution pump pipe 532. Add 30% by mass of industrial solid waste slurry, which is fly ash, to the solidification chamber 501, and inoculate the industrial solid waste slurry in the solidification chamber 501 with Bacillus pasteurellii and urease. The stirring drive motor 523 drives the solidification stirring drive shaft 52 to rotate, which in turn drives the stirring rod 521 to rotate, so as to fully stir and mix the industrial solid waste slurry and fly ash. Under the action of microorganisms, the heavy metals in the industrial solid waste slurry are adsorbed, chelated and stabilized by microorganisms. After solidification, a harmless solid waste product with no risk of heavy metal leaching is obtained, achieving the standard disposal of bulk industrial solid waste.
