Description

Technical Field

[0001] The invention relates to the technical field of solid waste treatment, in particular to a fly ash dechlorination treatment device with a multi-stage water washing function. Background Art

[0002] Fly ash from the incineration of domestic waste contains high salt content, mainly chloride salt. If it is to be used comprehensively, desalination measures should be taken to reduce the chlorine content to below 2%. The existing fly ash water washing and desalination technology mainly uses a stirring device to mix fly ash and water, and then uses a plate and frame filter press to separate the solid and liquid to allow water to remove the salt in the fly ash.

[0003] Because fly ash is a powdered solid, when it is washed with water during the mixing process, the powder tends to agglomerate together. The fly ash powder inside the agglomerate cannot come into contact with clean water, and the chloride salt cannot be completely removed, resulting in poor water washing effect. Summary of the invention

[0004] The object of the present invention is to provide a fly ash dechlorination treatment device with a multi-stage water washing function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution of a fly ash dechlorination treatment device with a multi-stage water washing function, the fly ash dechlorination treatment device includes a bracket, a water washing tank, a driving motor, a transmission shaft and a dispersing mechanism, the water washing tank is tightly connected to the bracket, the driving motor is tightly connected to the water washing tank, the output end of the driving motor is transmission-connected to the transmission shaft, the dispersing mechanism is tightly connected to the transmission shaft, the dispersing mechanism is used to stir the fly ash, and a plurality of groups of the dispersing mechanisms are arranged on the transmission shaft.

[0006] The bracket provides a stable working environment for the fly ash dechlorination treatment device. First, the fly ash that needs to be washed is added to the washing tank, and then clean water is added to the washing tank for washing. The drive motor is started and the torque is output to the transmission shaft, which in turn drives the transmission shaft to rotate, thereby driving the dispersion mechanism fixed on the transmission shaft to move. The dispersion mechanism is in the shape of blades and can stir the fly ash and water mixture in the washing tank, so as to mix the fly ash and water evenly, thereby promoting the precipitation of chloride salts.

[0007] Furthermore, the dispersion mechanism includes a connecting block, a frame, a variable component, a detection component and a dispersion component. The connecting block is tightly connected to the transmission shaft, the frame is rotatably connected to the connecting block, the variable component is tightly connected to the frame, the variable component is used to collect fly ash agglomerates, the detection component is tightly connected to the frame, the detection component is electrically connected to the variable component, the detection component is used to detect the size of fly ash agglomerates, the dispersion component is tightly connected to the frame, and the dispersion component is used to disperse fly ash agglomerates.

[0008] Because the diameter of fly ash particles is very small, the distance between particles is extremely short, and the van der Waals force between particles is much greater than the gravity of the particles themselves. Therefore, fly ash particles tend to attract each other and aggregate during the water washing process. The fly ash agglomerates are treated by a dispersion mechanism; the connecting block is used to fix the dispersion mechanism on the transmission shaft, and the frame is used to provide an installation basis for the variable component. Because the impact force of fly ash agglomerates of different sizes is different, the larger the fly ash agglomerates, the greater the impact force on the detection component. The size of the mesh hole on the variable component is controlled by detecting the size of this impact force.

[0009] Furthermore, an arc groove is provided in the connecting block, and a rotating shaft is provided on one side of the frame close to the connecting block, the rotating shaft is rotatably connected to the connecting block, and the dispersed component includes a connecting column, an arc slider, a resistor rod and an arc spring, the connecting column is tightly connected to the rotating shaft, the arc slider is tightly connected to the connecting column, the arc slider is slidably connected to the arc groove, the resistor rod is tightly connected to the arc slider, the resistor rod is arranged on both sides of the arc slider, one end of the arc spring is tightly connected to the resistor rod, and the other end of the arc spring is tightly connected to the inner wall of the arc groove, and two contacts are symmetrically arranged on the arc groove, and the two contacts are electrically connected to the resistor rod respectively.

[0010] During the mixing process, the distribution position of the fly ash agglomerates in the water washing tank is uneven. During the rotation of the dispersion mechanism, the fly ash agglomerates may fall on the upper part, middle part or lower part of the variable component. Because the rotating shaft is located at the midpoint of the frame, when the fly ash agglomerates are located in the upper part of the variable component, under the influence of the fly ash agglomerates' own weight, the frame will deflect to one side with the rotating shaft as the rotation center. Driven by the connecting column, the arc-shaped slider will deflect to one side along the arc-shaped groove, and the resistance rod on the same side will contact the The contact is formed, the circuit is connected, and the higher the fly ash agglomerates that fall on the upper part of the variable component are located, the longer the distance the resistor rod is offset to one side under the action of the lever, the shorter the distance the current flows through the resistor rod, and the smaller the relative resistance of the resistor rod. That is, the higher the fly ash agglomerates are located in the variable component, the smaller the relative resistance of the resistor rod, and the greater the current flowing through the circuit, and vice versa; when the fly ash agglomerates are located in the middle part of the variable component, the frame does not deflect, the resistor rod cannot touch the contact, and the circuit is not connected.

[0011] Furthermore, the dispersion component also includes a fixed electromagnet, a repelling magnet, a moving block, a supporting spring and an ultrasonic disperser. A slide groove is also provided on the frame. The fixed electromagnet is tightly connected to the slide groove, the repelling magnet is tightly connected to the moving block, the repelling magnet and the fixed electromagnet are arranged opposite to each other, the moving block is slidably connected to the slide groove, one end of the supporting spring is tightly connected to the moving block, the other end of the supporting spring is tightly connected to the inner wall of the slide groove, the ultrasonic disperser is tightly connected to the moving block, and the output end of the ultrasonic disperser faces the variable component. When the fly ash agglomerates are located in the upper part of the variable component: the facing ends of the fixed electromagnet and the repelling magnet are opposite poles; When the fly ash agglomerates are located in the lower half of the variable component: the facing ends of the fixed electromagnet and the repelling magnet are the same magnetic poles.

[0012] When the fly ash agglomerates are located in the middle part of the variable component, the frame does not deflect, the resistance rod cannot touch the contact point, and the circuit is not connected, that is, the fixed electromagnet is not energized. At this time, the moving block is supported by the supporting spring and is located in the middle position of the slide slot, and the ultrasonic disperser is also located in the middle position, thereby performing fixed-point dispersion of the fly ash agglomerates located in the middle part of the variable component; when the fly ash agglomerates are located in the upper half of the variable component, the negative pole of the power supply in the circuit is connected to the fixed electromagnet, that is, the facing ends of the fixed electromagnet and the repelling magnet are opposite magnetic poles, and under the action of the magnetic force, the moving block will be driven by the repelling magnet to move upward along the slide slot, the supporting spring will be stretched by the force, and the closer the fly ash agglomerates are to the upper part of the variable component, the smaller the relative resistance of the resistance rod, the greater the current flowing through the circuit, the greater the current transmitted to the fixed electromagnet, the greater the magnetic force of the fixed electromagnet, and the moving block will be moved upward along the slide slot. The longer the distance the block moves up along the slide slot, the longer the ultrasonic disperser fixed to the moving block is moved up; when the fly ash agglomerates are located in the lower half of the variable component, the positive pole of the power supply in the circuit is connected to the fixed electromagnet, that is, the facing ends of the fixed electromagnet and the repulsive magnet are poles of the same name, and under the action of the magnetic force, the moving block will be driven by the repulsive magnet to move downward along the slide slot, and the supporting spring will be compressed by force, and the lower the position of the fly ash agglomerates in the variable component, the smaller the relative resistance of the resistor rod, the greater the current flowing in the circuit, the greater the current transmitted to the fixed electromagnet, the greater the magnetic force of the fixed electromagnet, the longer the distance the moving block moves down along the slide slot, and the longer the ultrasonic disperser fixed to the moving block is moved down; that is, the position of the ultrasonic disperser is automatically adjusted according to the position of the fly ash agglomerates in the variable component, and the fixed-point dispersion of the fly ash agglomerates is achieved.

[0013] Furthermore, the variable component includes a fixed net and a movable net, a movable groove is provided on the frame, the fixed net is tightly connected to the frame, the fixed net is located on the water-facing surface of the dispersion mechanism, the mobile net is slidably connected to the movable groove, an adjustment component is provided in the movable groove, the adjustment component is electrically connected to the detection component, the adjustment component is used to adjust the position of the mobile net, and mesh holes are provided on both the fixed net and the mobile net.

[0014] In the initial state, the meshes on the fixed net and the mobile net overlap. At this time, the relative mesh diameter is the largest, which can intercept large-volume fly ash agglomerates. However, as the fly ash agglomerates are dispersed, the volume of the agglomerates will gradually decrease, and small-diameter fly ash agglomerates will directly pass through the mesh and cannot be intercepted on the fixed net. The relative position between the mobile net and the fixed net can be adjusted by adjusting the components to adjust the relative mesh size between the two and capture small-diameter fly ash agglomerates.

[0015] Furthermore, the detection component includes a protective shell, a force-bearing rod and a varistor. The protective shell is tightly connected to the frame, the force-bearing rod is rotatably connected to the protective shell, one end of the varistor is tightly connected to the inner wall of the protective shell, the detection end of the varistor abuts against the force-bearing rod, and the varistor is electrically connected to the adjustment component.

[0016] In the initial stage of dispersion, the fly ash agglomerates are large in volume and heavy in weight. When the dispersion mechanism rotates and stirs in the water washing tank, the fly ash agglomerates collide with the part of the force-bearing rod extending outside the protective shell, which will drive the force-bearing rod in the protective shell to deflect to the other side, thereby compressing the varistor. Moreover, as the fly ash agglomerates progress with the dispersion process, their volume will gradually decrease, the pressure on the varistor will be smaller, the resistance of the varistor will be smaller, and the current transmitted to the regulating component will be greater.

[0017] Furthermore, the adjustment component includes an adjusting electromagnet, an attraction block and an adjusting spring. The adjusting electromagnet is tightly connected to the inner wall of the movable groove. The attraction block and the adjusting electromagnet are arranged opposite to each other. The attraction block is tightly connected to the movable net. The attraction block is made of ferromagnetic material. One end of the adjusting spring is tightly connected to the inner wall of the movable groove, and the other end of the adjusting spring is tightly connected to the movable net.

[0018] Because the smaller the volume of fly ash agglomerates, the greater the current transmitted to the adjusting electromagnet by the varistor, the greater the magnetic force of the adjusting electromagnet, and the greater the attraction to the attraction block, thereby driving the moving net to move farther along the movable groove toward the side of the adjusting electromagnet, thereby reducing the area where the mesh holes on the moving net overlap with the mesh holes on the fixed net, and reducing the relative mesh diameter between the two, thereby realizing automatic adjustment of the size of the mesh holes on the variable component according to the volume of the fly ash agglomerates to capture fly ash agglomerates of different sizes.

[0019] Furthermore, the washing tank is provided with a feed inlet, a water inlet and a discharge port, and the water inlet is connected to an external water source.

[0020] The fly ash that needs to be washed is added into the washing tank from the feed port, and the washing water is added from the water inlet. The discharge port is used to discharge the washed fly ash for subsequent treatment. The washing tank can be arranged in multiple groups to achieve multi-stage washing of the fly ash, thereby improving the removal effect of chloride salts.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. When the fly ash agglomerates are located in the upper part of the variable component, the negative pole of the power supply in the circuit is connected to the fixed electromagnet, that is, the opposite ends of the fixed electromagnet and the repelling magnet are opposite poles. Under the action of the magnetic force, the moving block will be driven by the repelling magnet to move upward along the slide slot, and the supporting spring will be stretched by force. The closer the fly ash agglomerates are to the upper part of the variable component, the smaller the relative resistance of the resistor rod, the greater the current flowing through the circuit, the greater the current transmitted to the fixed electromagnet, the greater the magnetic force of the fixed electromagnet, the longer the distance the moving block moves upward along the slide slot, and the longer the distance the ultrasonic disperser fixed to the moving block is moved upward; when the fly ash agglomerates are located in the lower part of the variable component, the circuit The positive pole of the medium power supply is connected to the fixed electromagnet, that is, the facing ends of the fixed electromagnet and the repelling magnet are the same poles. Under the action of the magnetic force, the moving block will be driven by the repelling magnet to move downward along the slide slot, and the supporting spring will be compressed. The lower the position of the fly ash agglomerate in the variable component, the smaller the relative resistance of the resistor rod, the greater the current flowing through the circuit, the greater the current transmitted to the fixed electromagnet, the greater the magnetic force of the fixed electromagnet, the longer the distance the moving block moves downward along the slide slot, and the longer the distance the ultrasonic disperser fixed to the moving block is moved downward; that is, the position of the ultrasonic disperser is automatically adjusted according to the position of the fly ash agglomerate in the variable component, and the fixed-point dispersion of the fly ash agglomerate is achieved.

[0022] 2. The smaller the volume of fly ash agglomerates, the greater the current transmitted by the varistor to the adjusting electromagnet, the greater the magnetic force of the adjusting electromagnet, and the greater the attraction to the attraction block, thereby driving the mobile net to move farther along the movable slot toward the side of the adjusting electromagnet, so that the area where the mesh on the mobile net overlaps with the mesh on the fixed net is reduced, and the relative mesh diameter between the two is reduced, that is, the size of the mesh on the variable component is automatically adjusted according to the volume of the fly ash agglomerates to capture fly ash agglomerates of different sizes.

[0026] Example: Figure 1-Figure 13 As shown, the present invention provides a technical solution for a fly ash dechlorination treatment device with a multi-stage water washing function. The fly ash dechlorination treatment device includes a bracket 1, a water washing tank 2, a driving motor 3, a transmission shaft 4 and a dispersing mechanism 5. The water washing tank 2 is tightly connected to the bracket 1, the driving motor 3 is tightly connected to the water washing tank 2, the output end of the driving motor 3 is transmission-connected to the transmission shaft 4, the dispersing mechanism 5 is tightly connected to the transmission shaft 4, the dispersing mechanism 5 is used to stir the fly ash, and a plurality of groups of the dispersing mechanism 5 are arranged on the transmission shaft 4.

[0027] The bracket 1 provides a stable working environment for the fly ash dechlorination treatment device. First, the fly ash that needs to be washed is added into the washing tank 2, and then clean water is added into the washing tank 2 for washing. The driving motor 3 is started and the torque is output to the transmission shaft 4, which then drives the transmission shaft 4 to rotate, thereby driving the dispersion mechanism 5 fixed on the transmission shaft 4 to move. The dispersion mechanism 5 is in the shape of blades and can stir the fly ash and water mixture in the washing tank 2, so that the fly ash and water are evenly mixed, thereby promoting the precipitation of chloride salts.

[0028] The dispersion mechanism 5 includes a connecting block 51, a frame 52, a variable component 53, a detection component 54 and a dispersion component 55. The connecting block 51 is tightly connected to the transmission shaft 4, the frame 52 is rotatably connected to the connecting block 51, the variable component 53 is tightly connected to the frame 52, the variable component 53 is used to collect fly ash agglomerates, the detection component 54 is tightly connected to the frame 52, the detection component 54 is electrically connected to the variable component 53, the detection component 54 is used to detect the size of the fly ash agglomerates, the dispersion component 55 is tightly connected to the frame 52, and the dispersion component 55 is used to disperse the fly ash agglomerates.

[0029] Because the diameter of fly ash particles is very small, the distance between particles is extremely short, and the van der Waals force between particles is much greater than the gravity of the particles themselves. Therefore, fly ash particles tend to attract each other and aggregate during the water washing process, and the fly ash aggregates are treated by the dispersion mechanism 5; the connecting block 51 is used to fix the dispersion mechanism 5 on the transmission shaft 4, and the frame 52 is used to provide an installation basis for the variable component 53. Because the impact force of fly ash aggregates of different sizes is different, the larger the fly ash aggregate, the greater the impact force on the detection component 54. The size of the mesh hole on the variable component 53 is controlled by detecting the size of this impact force.

[0030] An arc groove 511 is provided in the connecting block 51, and a rotating shaft 521 is provided on one side of the frame 52 close to the connecting block 51. The rotating shaft 521 is rotatably connected to the connecting block 51. The dispersion component 55 includes a connecting column 551, an arc slider 552, a resistor rod 553 and an arc spring 554. The connecting column 551 is tightly connected to the rotating shaft 521, the arc slider 552 is tightly connected to the connecting column 551, the arc slider 552 is slidingly connected to the arc groove 511, the resistor rod 553 is tightly connected to the arc slider 552, the resistor rod 553 is arranged on both sides of the arc slider 552, one end of the arc spring 554 is tightly connected to the resistor rod 553, and the other end of the arc spring 554 is tightly connected to the inner wall of the arc groove 511. Two contacts 512 are symmetrically arranged on the arc groove 511, and the two contacts 512 are electrically connected to the resistor rod 553 respectively.

[0031] During the stirring process, the distribution position of the fly ash agglomerates in the washing tank 2 is uneven. During the rotation of the dispersion mechanism 5, the fly ash agglomerates may fall on the upper part, middle part or lower part of the variable component 53. Because the rotating shaft 521 is located at the midpoint of the frame 52, when the fly ash agglomerates are located in the upper part of the variable component 53, under the influence of the fly ash agglomerates' own weight, the frame 52 will deflect to one side with the rotating shaft 521 as the rotation center. Driven by the connecting column 551, the arc-shaped slider 552 will deflect to one side along the arc-shaped groove 511, and the resistor rod 553 on the same side will contact the contact. Point 512, the circuit is connected, and the higher the position of the fly ash agglomerates falling on the upper half of the variable component 53, the longer the distance that the resistor rod 553 is offset to one side under the action of the lever, the shorter the distance that the current flows through the resistor rod 553, and the smaller the relative resistance of the resistor rod 553. That is, the higher the position of the fly ash agglomerates in the variable component 53, the smaller the relative resistance of the resistor rod 553, and the greater the current flowing through the circuit, and vice versa; when the fly ash agglomerates are located in the middle part of the variable component 53, the frame 52 does not deflect, the resistor rod 553 cannot contact the contact 512, and the circuit is not connected.

[0032] The dispersion component 55 further includes a fixed electromagnet 555, a repelling magnet 556, a moving block 557, a supporting spring 558 and an ultrasonic disperser 559. A slide groove 522 is further provided on the frame 52. The fixed electromagnet 555 is fastened to the slide groove 522, the repelling magnet 556 is fastened to the moving block 557, the repelling magnet 556 and the fixed electromagnet 555 are arranged opposite to each other, the moving block 557 is slidably connected to the slide groove 522, one end of the supporting spring 558 is fastened to the moving block 557, the other end of the supporting spring 558 is fastened to the inner wall of the slide groove 522, the ultrasonic disperser 559 is fastened to the moving block 557, and the output end of the ultrasonic disperser 559 faces the variable component 53. When the fly ash agglomerates are located in the upper part of the variable component 53: the facing ends of the fixed electromagnet 555 and the repelling magnet 556 are opposite poles; When the fly ash agglomerates are located in the lower half of the variable component 53, the facing ends of the fixed electromagnet 555 and the repelling magnet 556 are the same magnetic poles.

[0033] When the fly ash agglomerates are located in the middle part of the variable component 53, the frame 52 does not deflect, the resistor rod 553 cannot contact the contact 512, and the circuit is not connected, that is, the fixed electromagnet 555 is not energized. At this time, the moving block 557 is supported by the support spring 558 and is located in the middle position of the slide slot 522. The ultrasonic disperser 559 is also located in the middle position, thereby performing fixed-point dispersion on the fly ash agglomerates located in the middle part of the variable component 53; when the fly ash agglomerates are located in the upper half of the variable component 53, the current in the circuit is not connected. The negative pole of the power source is connected to the fixed electromagnet 555, that is, the facing ends of the fixed electromagnet 555 and the repelling magnet 556 are opposite poles. Under the action of the magnetic force, the moving block 557 will be driven by the repelling magnet 556 to move upward along the slide slot 522, and the supporting spring 558 is stretched by the force. In addition, the closer the fly ash agglomerate is to the variable component 53, the smaller the relative resistance value of the resistor rod 553, the greater the current flowing through the circuit, the greater the current transmitted to the fixed electromagnet 555, and the greater the magnetic force of the fixed electromagnet 555. The longer the distance 557 moves up along the chute 522, the longer the ultrasonic disperser 559 fixed to the moving block 557 is moved up; when the fly ash agglomerates are located in the lower half of the variable component 53, the positive pole of the power supply in the circuit is connected to the fixed electromagnet 555, that is, the opposite ends of the fixed electromagnet 555 and the repelling magnet 556 are the same magnetic poles, and under the action of the magnetic force, the moving block 557 will be driven by the repelling magnet 556 to move downward along the chute 522, the supporting spring 558 is compressed, and the fly ash agglomerates are in the variable The lower the position of the component 53 is, the smaller the relative resistance of the resistor rod 553 is, the greater the current flowing through the circuit is, the greater the current transmitted to the fixed electromagnet 555 is, the greater the magnetic force of the fixed electromagnet 555 is, the longer the distance that the moving block 557 moves downward along the slide groove 522 is, and the longer the distance that the ultrasonic disperser 559 fixed to the moving block 557 is moved downward is; that is, the position of the ultrasonic disperser 559 is automatically adjusted according to the position of the fly ash agglomerates in the variable component 53, thereby achieving fixed-point dispersion of the fly ash agglomerates.

[0034] The variable component 53 includes a fixed net 531 and a movable net 532. A movable groove 523 is provided on the frame 52. The fixed net 531 is tightly connected to the frame 52. The fixed net 531 is located on the water-facing surface of the dispersion mechanism 5. The movable net 532 is slidably connected to the movable groove 523. An adjustment component 56 is provided in the movable groove 523. The adjustment component 56 is electrically connected to the detection component 54. The adjustment component 56 is used to adjust the position of the mobile net 532. Both the fixed net 531 and the mobile net 532 are provided with mesh holes.

[0035] In the initial state, the meshes on the fixed net 531 and the mobile net 532 overlap. At this time, the relative mesh diameter is the largest, and large-volume fly ash agglomerates can be retained. However, as the fly ash agglomerates are dispersed, the volume of the agglomerates will gradually decrease, and small-diameter fly ash agglomerates will directly pass through the mesh and cannot be retained on the fixed net 531. The relative position between the mobile net 532 and the fixed net 531 is adjusted by adjusting the adjustment component 56 to adjust the relative mesh size between the two and capture small-diameter fly ash agglomerates.

[0036] The detection component 54 includes a protective shell 541, a force-bearing rod 542 and a varistor 543. The protective shell 541 is tightly connected to the frame 52, the force-bearing rod 542 is rotatably connected to the protective shell 541, one end of the varistor 543 is tightly connected to the inner wall of the protective shell 541, the detection end of the varistor 543 abuts against the force-bearing rod 542, and the varistor 543 is electrically connected to the adjustment component 56.

[0037] In the initial stage of dispersion, the fly ash agglomerates are large in volume and heavy in weight; when the dispersion mechanism 5 rotates and stirs in the water washing tank 2, the fly ash agglomerates will drive the force-bearing rod 542 in the protective shell 541 to deflect to the other side when colliding with the part of the force-bearing rod 542 extending outside the protective shell 541, thereby compressing the varistor 543, and as the volume of the fly ash agglomerates gradually decreases with the progress of the dispersion process, the pressure on the varistor 543 will be smaller, the resistance value of the varistor 543 will be smaller, and the current transmitted to the adjustment component 56 will be greater.

[0038] The adjustment component 56 includes an adjustment electromagnet 561, an attraction block 562 and an adjustment spring 563. The adjustment electromagnet 561 is tightly connected to the inner wall of the movable groove 523. The attraction block 562 and the adjustment electromagnet 561 are arranged opposite to each other. The attraction block 562 is tightly connected to the moving net 532. The attraction block 562 is made of ferromagnetic material. One end of the adjustment spring 563 is tightly connected to the inner wall of the movable groove 523, and the other end of the adjustment spring 563 is tightly connected to the moving net 532.

[0039] Because the smaller the volume of the fly ash agglomerates, the greater the current transmitted to the adjusting electromagnet 561 by the varistor 543, the greater the magnetic force of the adjusting electromagnet 561, and the greater the attraction to the attraction block 562, thereby driving the mobile net 532 to move farther along the movable slot 523 toward the side of the adjusting electromagnet 561, so that the area where the mesh on the mobile net 532 overlaps with the mesh on the fixed net 531 is reduced, and the relative mesh diameter between the two is reduced, thereby realizing automatic adjustment of the size of the mesh on the variable component 53 according to the volume of the fly ash agglomerates to capture fly ash agglomerates of different sizes.

[0040] The washing tank 2 is provided with a feed inlet 21, a water inlet 22 and a discharge port 23, and the water inlet 22 is connected to an external water source.

[0041] Fly ash that needs to be washed is added to the washing tank 2 from the feed port 21, and washing water is added from the water inlet 22. The discharge port 23 is used to discharge the washed fly ash for subsequent treatment. The washing tank 2 can be arranged in multiple groups to achieve multi-stage washing of the fly ash, thereby improving the removal effect of chloride salts.

[0042] Working principle of the present invention: During the stirring process, the distribution position of the fly ash agglomerates in the washing tank 2 is uneven. During the rotation of the dispersion mechanism 5, the fly ash agglomerates may fall on the upper part, the middle part or the lower part of the variable component 53. When the fly ash agglomerates are located in the middle part of the variable component 53, the frame 52 does not deflect, the resistance rod 553 cannot contact the contact 512, and the circuit is disconnected, that is, the fixed electromagnet 555 is not energized. At this time, the moving block 557 is supported by the support spring 558 and is located in the middle position of the slide slot 522. The ultrasonic disperser 55 9 is also located in the middle position, thereby performing fixed-point dispersion on the fly ash agglomerates located in the middle part of the variable component 53; when the fly ash agglomerates are located in the upper half of the variable component 53, the negative pole of the power supply in the circuit is connected to the fixed electromagnet 555, that is, the facing ends of the fixed electromagnet 555 and the repelling magnet 556 are opposite poles, and under the action of the magnetic force, the moving block 557 will be driven by the repelling magnet 556 to move upward along the slide groove 522, and the supporting spring 558 will be stretched by the force, and the closer the fly ash agglomerates are to the upper part of the variable component 53, the smaller the relative resistance value of the resistor rod 553 will be. The greater the current flowing through the circuit, the greater the current transmitted to the fixed electromagnet 555, the greater the magnetic force of the fixed electromagnet 555, the longer the distance that the moving block 557 moves up along the slide groove 522, and the longer the distance that the ultrasonic disperser 559 fixed to the moving block 557 is moved up; when the fly ash agglomerates are located in the lower half of the variable component 53, the positive pole of the power supply in the circuit is connected to the fixed electromagnet 555, that is, the opposite ends of the fixed electromagnet 555 and the repelling magnet 556 are the same magnetic poles, and under the action of the magnetic force, the moving block 557 will be driven by the repelling magnet 556 to slide along the slide groove 522. The groove 522 moves downward, the support spring 558 is compressed, and the lower the position of the fly ash agglomerates in the variable component 53, the smaller the relative resistance of the resistor rod 553, the greater the current flowing through the circuit, the greater the current transmitted to the fixed electromagnet 555, the greater the magnetic force of the fixed electromagnet 555, the longer the distance that the moving block 557 moves downward along the slide groove 522, and the longer the distance that the ultrasonic disperser 559 fixed to the moving block 557 is moved downward; that is, the position of the ultrasonic disperser 559 is automatically adjusted according to the position of the fly ash agglomerates in the variable component 53.
