Description

Technical Field

[0001] This invention relates to the field of ultrafine dust collection, and more specifically, to a high-concentration ultrafine dust collector. Background Technology

[0002] With the development of dust removal technology and the increasing environmental protection requirements, dust collectors are being used in a wider range of applications. Currently, dust collectors can be used to treat high-temperature, high-humidity, sticky, explosive, and abrasive flue gas, and even filter air containing ultrafine dust.

[0003] Baghouse dust collectors, also known as filter dust collectors, are a type of dry, high-efficiency dust collector. They utilize bag-type filter elements made of woven fiber fabric to capture solid particles in dusty gases. Baghouse dust collectors consist of a dust hopper, upper chamber, middle chamber, and lower chamber. The upper, middle, and lower chambers are compartmentalized. However, when handling gases containing a large number of large dust particles, the filter bags are prone to wear, and different exhaust gases have different requirements for the filter bags, necessitating the replacement of different filter bags.

[0004] Patent 1: Chinese patent CN113476980B discloses a high-concentration ultrafine dust collector. By setting a spiral filter screen with the mesh diameter gradually decreasing from the inside to the outside along the spiral direction, it can achieve stratified filtration of dust particles of different diameters. At the same time, due to the spiral structure design, the dust slides to the bottom of the filter screen under the action of gravity, which facilitates the cleaning of dust particles and has a good filtration effect. Through the round hole at the rear end of the baffle, the blocking area of ​​the baffle can be changed for different exhaust gases to achieve different filtration effects. At the same time, by changing the position of the baffle 7, the position of the airflow into the filter screen can be controlled, which can achieve stratified filtration of dust particles to a certain extent.

[0005] Patent 2: Chinese Patent No. CN215232823U discloses a dust collector for the production and processing of ultrafine fly ash. It adopts bag dust collection, which has a simple structure, low cost, high dust collection efficiency, long service life, and is easy to install and disassemble. By setting pulse tubes and spray pipes, it is easy to remove dust from the bag with high-pressure air jets, thereby improving the dust collection effect of the bag. By setting square cavities, it is easy to install multiple bag filter devices, resulting in better dust collection effect.

[0006] Existing patents offer solutions to the above problems, but they all use filter screens or filter bags for filtration. This causes dust to clog the filter holes after a certain period of operation, affecting the filtration speed and requiring cleaning, making them inconvenient to use. Summary of the Invention

[0007] In view of the problems existing in the prior art, the purpose of this invention is to provide a high-concentration ultrafine dust collector.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) This solution sets up an ultrafine dust treatment mechanism, so that the exhaust fan delivers air rich in ultrafine dust to the inside of the treatment box. Then, the mist inside the treatment box performs the initial dust reduction on the ultrafine dust in the air. Then, the first electric telescopic rod drives the extrusion plate to move back and forth inside the two extrusion hoods, thereby repeatedly extracting and discharging the air and mist inside the extrusion hoods, thereby increasing the flow of air and mist and improving the dust reduction effect on the ultrafine dust in the air.

[0022] (2) In this scheme, after the air pressure inside the main body of the treatment box reaches a certain amount, the extrusion rod contacts the trigger switch, and the trigger switch controls the first blower to run. This allows the air pressure to push the extrusion rod, causing the extrusion rod to move the baffle plate upward. The upward movement of the baffle plate will squeeze the air and mist inside the main body of the treatment box, causing the air pressure to push the baffle plate and the baffle plate to no longer contact each other. This allows the air and mist to flow out from the discharge hole, first colliding with the baffle plate, and then colliding with the inner surface of the main body of the treatment box, which greatly improves the dust reduction effect of ultrafine dust.

[0023] (3) This solution uses a second exhaust fan to simultaneously extract mist and air, then delivers it to the inside of the sealed shell, and then it flows out from the inside of the blow hole at the bottom of the sealed shell. The air flowing out from the blow hole will come into contact with the water inside the water storage shell, thereby increasing the air flow while allowing the water to reduce the dust in the air again, further optimizing the dust reduction effect.

[0024] (4) This solution sets up an ultrafine dust separation mechanism so that when the concentration of ultrafine dust inside the connecting cylinder reaches a certain value, the connecting cylinder is rotated and its position is changed to avoid the continuous flow of backflow water into the connecting cylinder, which would cause continuous fluctuations in the connecting cylinder and affect the sedimentation of ultrafine dust. Secondly, the water source is changed to a new water source to improve the atomization effect and make the treatment effect of ultrafine dust better.

[0025] (5) After the ultrafine dust settles, the connecting cylinder is rotated so that the connecting cylinder drives the extrusion block to extrude the transmission rod, which in turn drives the sealing plate to move down, thereby discharging the ultrafine dust inside the settling tank, achieving the separation of ultrafine dust and water, and improving the reuse rate of some water.

[0026] (6) After the sealing disc moves down, the sealing disc will rotate under the action of the torsion spring. The rotation of the sealing disc will cause the sealing disc to tilt, thereby improving the flow of ultrafine dust and residual water through the tilted sealing disc, reducing the amount of ultrafine dust remaining on the surface of the sealing disc, and improving the cleaning effect.

Detailed Implementation

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 13 A high-concentration ultrafine dust collector includes a treatment box body 1, a support frame 2 fixedly installed on the lower surface of the treatment box body 1, an ultrafine dust treatment mechanism 3 arranged inside the treatment box body 1, the ultrafine dust treatment mechanism 3 being used to absorb and treat external ultrafine dust, and an ultrafine dust separation mechanism 4 arranged inside the treatment box body 1 and below the ultrafine dust treatment mechanism 3, the ultrafine dust separation mechanism 4 being used to separate the ultrafine dust after dust settling from the water for convenient unified treatment;

[0044] The ultrafine dust treatment mechanism 3 includes a guide tube 31 fixed to the outer surface of the front side of the treatment box body 1. A fan 32 is fixedly installed at one end of the guide tube 31 away from the treatment box body 1, and a one-way valve 33 is fixedly installed at the other end of the guide tube 31. A baffle plate 34 is slidably connected inside the treatment box body 1. Four extrusion covers 35 are fixedly installed on the upper surface of the baffle plate 34. Two extrusion plates 36 are arranged between the four extrusion covers 35. A flow groove 37 is opened on the top of the four extrusion covers 35 away from the extrusion plates 36. An atomizer 313 is fixedly installed on the top of the treatment box body 1.

[0045] The purpose of the one-way valve 33 is to open when the exhaust fan 32 supplies air to the interior of the processing box body 1, and to close when the exhaust fan 32 stops running, so as to prevent air from being discharged from the connection between the guide tube 31 and the processing box body 1.

[0046] like Figure 1 - Figure 4 As shown, the ultrafine dust treatment mechanism 3 also includes a telescopic rod 38 fixed to the middle of one side of the extrusion plate 36. A telescopic cylinder 310 is sleeved on the outer surface of the telescopic rod 38. A first electric telescopic rod 311 is fixedly installed on the side surface of the treatment box body 1. A linkage rod 312 is fixedly installed at the output end of the first electric telescopic rod 311. One end of the linkage rod 312 located inside the treatment box body 1 is fixedly connected to one end of the telescopic cylinder 310. A sliding plate 314 is fixedly installed at one end of the linkage rod 312. A sliding groove 315 is opened on one side of the treatment box body 1. An extrusion mechanism 39 is provided at the bottom of the barrier plate 34.

[0047] like Figure 1 - Figure 4 As shown, the length of the sliding plate 314 is twice the length of the sliding groove 315, and both ends of the sliding plate 314 penetrate the sliding groove 315 and extend into the interior of the processing box body 1. The two ends of the sliding plate 314 are located on both sides of the sliding groove 315, and the outer surface of the sliding plate 314 is slidably connected to the processing box body 1. The outer surface of the extrusion plate 36 is slidably connected to the inner surface of the extrusion cover 35. The height of the guide cylinder 31 near the processing box body 1 is higher than the height of the barrier plate 34.

[0048] In practical applications, when using atomization to suppress ultrafine dust, the mixing degree between the mist and the ultrafine dust is generally low, which affects the dust suppression effect.

[0049] During dust suppression, the operation of the exhaust fan 32, the first electric telescopic rod 311, and the atomizer 313 are controlled first. The operation of the atomizer 313 causes it to spray water mist onto the top of the treatment chamber body 1. Meanwhile, when the exhaust fan 32 is running, it draws in outside air through the guide tube 31 into the interior of the treatment chamber body 1, allowing the ultrafine dust mixed in the air to enter the interior of the treatment chamber body 1 simultaneously. The ultrafine dust entering the treatment chamber body 1 mixes with the water mist inside, achieving the initial dust suppression purpose. To further enhance the mixing effect of the water mist and ultrafine dust, the operation of the first electric telescopic rod 311 is used to increase airflow. The reciprocating movement of the output end of the first electric telescopic rod 311 drives the linkage rod 312 to reciprocate. 2. The reciprocating movement will drive the sliding plate 314 and the telescopic cylinder 310 to reciprocate. During the reciprocating sliding process of the sliding plate 314, the sliding plate 314 will continuously seal the sliding groove 315. The reciprocating movement of the telescopic cylinder 310 will drive the telescopic rod 38 to reciprocate, and then the telescopic rod 38 will drive the extrusion plate 36 to reciprocate. When the extrusion plate 36 moves to one of the two extrusion covers 35, it will cause the extrusion plate 36 to extrude the air inside the extrusion cover 35, and at the same time extract the air inside the other extrusion cover 35. Thus, when the extrusion plate 36 reciprocates, it can squeeze out the air in one extrusion cover 35, while the other extrusion cover 35 draws in the mist and air inside the processing box body 1, thereby improving the fluidity of air and mist and achieving the purpose of improving the mixing degree of air and mist.

[0050] like Figure 4 - Figure 7As shown, the extrusion mechanism 39 includes a mounting plate 391 fixed to the inner surface of the processing box body 1. An air storage cylinder 392 is fixedly installed inside the mounting plate 391. An extrusion rod 393 is slidably connected inside the air storage cylinder 392. A first spring 394 is fixedly installed at one end of the extrusion rod 393 inside the air storage cylinder 392. An exhaust hole 395 is opened on the lower surface of the air storage cylinder 392. A first blower 396 is fixedly installed on the outer surface of the processing box body 1. The output end is fixedly connected to the lower surface of the air storage cylinder 392. The baffle plate 34 is uniformly provided with extrusion grooves 397 that penetrate the baffle plate 34. A second spring 398 is fixedly installed inside the lower surface of the baffle plate 34. A flow limiting plate 3910 is fixedly installed at the bottom of the second spring 398. A blower mechanism 399 is provided at the bottom of the flow limiting plate 3910. A trigger switch 3911 is fixedly installed at the bottom inside the air storage cylinder 392. The extrusion rod 393 penetrates and slides inside the flow limiting plate 3910.

[0051] A groove is provided inside the flow limiting plate 3910 for the second spring 398 to retract, so that the second spring 398 can retract completely into the flow limiting plate 3910, ensuring that the flow limiting plate 3910 and the barrier plate 34 are in close contact with each other.

[0052] When gas is continuously supplied into the processing box body 1, although the gas pressure inside the processing box body 1 increases, the flow restriction plate 3910 cannot be pushed open because the baffle plate 34 can move downward.

[0053] Before the blower mechanism 399 is operated, it needs to cooperate with the ultrafine dust treatment mechanism 3. The baffle plate 34 in the ultrafine dust treatment mechanism 3 is slidably set. Its purpose is to block the air above the baffle plate 34 so that the air can be further processed when the exhaust fan 32 delivers air to the top of the treatment box body 1. As the air increases, the baffle plate 34, which is slidably connected to the treatment box body 1, will move downward. After the baffle plate 34 moves a certain distance, the extrusion rod 393 will contact the trigger switch 3911, at which time the extrusion mechanism 39 starts to operate.

[0054] In actual use, even after the air and mist mix, a small amount of dust will still continuously flow with the airflow. Therefore, by setting up a squeezing mechanism 39, as more and more air accumulates inside the processing chamber 1, the air pressure pushes the baffle plate 34 downwards. The downward movement of the baffle plate 34 causes the squeezing rod 393 to move downwards. The downward movement of the squeezing rod 393 causes it to contact the trigger switch 3911, which then controls the exhaust fan 32 to stop and the first blower 396 to start. The exhaust fan 32 stopping prevents outside air from entering the processing chamber 1, while the first blower 396 blowing air into the air storage cylinder 392. Because the exhaust port 395 has a small diameter, although some air can be discharged from inside the exhaust port 395, the intake volume is much greater than the output volume. The extrusion rod 393 will inevitably move upward. The upward movement of the extrusion rod 393 will drive the baffle plate 34 to move upward. When the baffle plate 34 moves upward, the space above the baffle plate 34 will decrease, resulting in an increase in air pressure. This will cause the gas to push the flow limiting plate 3910 downward, so that the flow limiting plate 3910 will no longer seal the extrusion groove 397. This will allow the mist, air, and a small amount of condensed water to flow through the extrusion groove 397 to the surface of the flow limiting plate 3910 and collide with it. Then, under the action of the flow limiting plate 3910, the mist and air will be guided to flow in all directions towards the inner surface of the treatment box body 1. This will cause the mist and air to collide again. This time, the collision occurs with the inner surface of the treatment box body 1. Since a large amount of water adheres to the inner surface of the treatment box body 1, the dust reduction effect of ultrafine dust in the air can be further improved.

[0055] like Figure 5 and Figure 6 As shown, the blower mechanism 399 includes a sealing shell 3991 fixed to the lower surface of the flow limiting plate 3910. The lower surface of the sealing shell 3991 is evenly provided with blower holes 3992, and a second exhaust fan 3993 is fixedly installed on the outer surface of the sealing shell 3991. A water storage shell 3994 is fixedly installed on the inner surface of the processing box body 1 and below the sealing shell 3991. A lower water tank 3995 is provided in the middle of the water storage shell 3994.

[0056] like Figure 4 - Figure 7 As shown, the output end of the second exhaust fan 3993 is located inside the sealing shell 3991. The bottom surface of the sealing shell 3991 is designed to be inclined, and it is inclined from high to low from the periphery of the sealing shell 3991 towards the water tank 3995. The upper surface of the flow limiting plate 3910 is in contact with the upper surface of the barrier plate 34.

[0057] In actual use, air needs to flow continuously, but the amount of air coming into contact with water is relatively small. This results in only a moderate dust suppression effect when relying solely on the mixture of mist and water. Therefore, by setting up a blower mechanism 399, after the mist and air are processed by the extrusion mechanism 39, some of the mist will condense into water. The water will flow downwards from around the flow restrictor 3910 and then enter the interior of the water storage tank 3994. With the inclined design of the bottom surface of the water storage tank 3994, the water will flow evenly downwards towards the water tank 3995. Meanwhile, the second exhaust fan 3993 is controlled by the control switch to operate. The operation of the second exhaust fan 3993 will cause the second exhaust fan 3993 to draw in the air and mist below the flow limiting plate 3910, and then transport the drawn air to the inside of the sealing shell 3991, and then discharge it through the inside of the blowing hole 3992. The discharged air from the blowing hole 3992 blows downward and comes into contact with the water in the water storage shell 3994, achieving dust suppression again. After being blown out, the mixing degree of mist and air is further improved, achieving the purpose of further optimizing the dust suppression effect.

[0058] like Figure 8 - Figure 10 As shown, the ultrafine dust separation mechanism 4 includes a fixed column 41 fixed to the lower surface of the interior of the processing box body 1. A rotating disk 42 is rotatably connected to the upper surface of the fixed column 41. Three connecting cylinders 43 with openings at both the top and bottom are fixedly installed on the upper surface of the rotating disk 42. A sedimentation tank 44 penetrating the top and bottom of the fixed column 41 is opened inside the fixed column 41. A rotating motor 45 is fixedly installed on the lower surface of the processing box body 1. The output end of the rotating motor 45 is fixedly connected to the lower surface of the rotating disk 42. A guide plate 46 is fixedly installed inside the processing box body 1 and above the connecting cylinders 43. A drain pipe 47 is fixedly installed on the lower surface of the guide plate 46. An annular disk 48 is fixedly installed on the inner surface of the processing box body 1 and outside the three connecting cylinders 43. A water supply pipe 410 is fixedly installed on one side of the annular disk 48. A water supply port 411 is opened on the outer surface of the contact surface between the three connecting cylinders 43 and the annular disk 48. A sewage discharge mechanism 49 is provided inside the sedimentation tank 44.

[0059] The atomizer 313 is supplied with water through the water inside the connecting cylinder 43. The principle of water supply is that the water inside the connecting cylinder 43 first flows through the water inlet 411 to the inside of the water supply pipe 410, and then flows from the inside of the water supply pipe 410 to the inside of the atomizer 313. When the connecting cylinder 43 rotates, the water inlet 411 will no longer be connected to the water supply pipe 410. At this time, the annular disc 48 seals the water inlet 411. In order to improve the sealing effect, a sealing ring is provided between the annular disc 48 and the connecting cylinder 43 to increase the sealing between the two.

[0060] like Figure 1 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, the sewage discharge mechanism 49 includes two reciprocating rods 492 that slide inside the fixed column 41. A third spring 493 is fixedly installed on the surface of one end of each of the two reciprocating rods 492 inside the fixed column 41. A sealing disc 494 is provided on the opposite side of the bottom end of the two reciprocating rods 492. A transmission rod 495 is fixedly installed on the outer surface of the bottom end of the reciprocating rods 492. A squeezing block 496 is fixedly installed on the outer surface of the connecting cylinder 43. The squeezing block 496 is triangular. A collection box 497 is fixedly installed on the lower surface of the support frame 2. A rotating mechanism 498 is provided at the bottom of the reciprocating rods 492.

[0061] In actual use, after water is atomized and recovered, it will contain a large amount of ultrafine dust over time. When the concentration reaches a certain level, the ultrafine dust can easily clog the atomizer 313. Therefore, an ultrafine dust separation mechanism 4 is installed. During the downward flow of water inside the treatment tank 1, the water passes through the guide plate 46 and converges at its lowest point before entering the drain pipe 47. From there, it enters the connecting cylinder 43 directly below the drain pipe 47. As time increases, the concentration of ultrafine dust in the circulating water becomes higher. When it is necessary to separate the ultrafine dust from the water, the output of the rotating motor 45 is controlled by a control switch. The rotation of the motor 45 drives the rotating disk 42 to rotate, which in turn drives the three connecting cylinders 43 to rotate, thus replacing the water supply connecting cylinders 43. The connecting cylinder 43 rich in ultrafine dust moves to the top of the sedimentation tank 44 as the rotating disk 42 rotates. Then, the ultrafine dust settles inside the sedimentation tank 44. After a certain period of sedimentation, the ultrafine dust settles inside the sedimentation tank 44. When the rotating disk 42 is rotated again, only the water inside the connecting cylinder 43 will rotate. The ultrafine dust and water settled inside the sedimentation tank 44 will not rotate with it. When the connecting cylinder 43 rotates to an angle that intersects with the sedimentation tank 44, the rotating disk 42 is above the sedimentation tank 44. When the connecting cylinder 43 rotates, it will drive the squeezing block 496 to rotate. The rotation of the squeezing block 496 will cause the squeezing block 496 to squeeze the transmission rod 495, causing the transmission rod 495 to move downward. The downward movement of the transmission rod 495 will drive the reciprocating rod 492 to move downward, and then the reciprocating rod 492 will drive the sealing disk 494 to move downward, so that the sealing disk 494 no longer seals the sedimentation tank 44, allowing the ultrafine dust and water settled inside the sedimentation tank 44 to flow out, thus completing the separation of the settled ultrafine dust and water. The settled ultrafine dust and a small amount of residual water will flow into the collection box 497.

[0062] like Figure 13As shown, the rotating mechanism 498 includes a rotating rod 4981 that rotates inside the sealing disk 494. A torsion spring 4982 is fixedly connected to one end of the rotating rod 4981 inside the sealing disk 494. A limit rod 4983 is fixedly installed on the outer surface of the rotating rod 4981. A limit groove 4984 is formed inside the sealing disk 494 and on one side of the rotating rod 4981.

[0063] like Figure 1 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13 As shown, one end of the limiting rod 4983 is located inside the limiting groove 4984, and the outer surface of the limiting rod 4983 is slidably connected to the inner surface of the limiting groove 4984. One end of the torsion spring 4982 is fixedly connected to the inner surface of the sealing disc 494. One end of the rotating rod 4981 is fixedly connected to the inner surface of the reciprocating rod 492. The top end of the third spring 493 is fixedly connected to the inner surface of the fixing column 41. The sealing disc 494 is located below the sedimentation tank 44, and one end of the transmission rod 495 is located on one side of the extrusion block 496.

[0064] When the sealing disc 494 is in a horizontal state, that is, in the initial state, its torsion spring 4982 is in a compressed state. Then, when the sealing disc 494 is no longer restricted, the compressed torsion spring 4982 drives the rotating rod 4981 to rotate, which in turn drives the sealing disc 494 to rotate. The limiting rod 4983 and the limiting groove 4984 are set to limit the rotation angle of the limiting rod 4983, so that the limiting rod 4983 can only rotate forty-five degrees, which facilitates subsequent reset.

[0065] In actual use, because the sealing disc 494 is horizontally designed, a large amount of ultrafine dust remains on the upper surface of the sealing disc 494 after it moves downwards, resulting in poor cleaning effect of ultrafine dust. Based on this, by setting a rotating mechanism 498, after the sealing disc 494 moves downwards, there will be a certain gap between the sealing disc 494 and the fixed column 41, so that the sealing disc 494 is no longer restricted. Then, the torsion spring 4982 drives the rotating rod 4981 to rotate. The rotation of the rotating rod 4981 will drive the sealing disc 494 to rotate, causing the sealing disc 494 to tilt. This can improve the fluidity of ultrafine dust and water, and reduce the amount of ultrafine dust residue on the upper surface of the sealing disc 494.

[0066] Instructions for use: During operation, the exhaust fan 32 first draws outside air into the processing chamber body 1. Once inside, the air mixes with the mist sprayed by the atomizer 313, achieving initial dust suppression of ultrafine dust particles. Simultaneously, the output of the first electric telescopic rod 311 causes the extrusion plate 36 to reciprocate within the two extrusion hoods 35. This allows for repeated extraction and decompression of the air inside the extrusion hoods 35, increasing the mixing degree of air and mist. To improve dust suppression, as the air volume above the baffle plate 34 increases, the baffle plate 34 moves downward under the pressure. This downward movement of the baffle plate 34 causes the extrusion rod 393 to contact the trigger switch 3911. The trigger switch 3911 then controls the first blower 396 to blow air into the air tank 392. Under the pressure, the extrusion rod 393 rises rapidly, pushing the baffle plate 34 upward. As the baffle plate 34 moves upward, it compresses the gas inside the treatment chamber 1, causing the gas to push the flow restriction plate 3910, thus improving the dust suppression effect. 910 no longer seals the exhaust port 395, allowing air and mist to flow rapidly under air pressure and collide with the inner wall of the treatment box body 1. Then, the second exhaust fan 3993 draws in the mist and air, causing them to flow towards the water inside the water storage tank 3994. This collision between the mist and air and the water inside the water storage tank 3994 further enhances the dust suppression effect on ultrafine dust in the air. After dust suppression, the ultrafine dust drips onto the upper surface of the guide plate 46 and then flows into the interior of the connecting cylinder 43 through the drain pipe 47. When the concentration of ultrafine dust inside the connecting cylinder 43 is high, the connecting cylinder 43 is rotated to the top of the sedimentation tank 44. After a certain period of sedimentation, the ultrafine dust settles into the interior of the sedimentation tank 44. Then, the connecting cylinder 43 is rotated again, causing the extrusion block 496 to extrude the transmission rod 495. This causes the transmission rod 495 to move the sealing disc 494 downward, so that the sealing disc 494 no longer seals the sedimentation tank 44. As a result, the ultrafine dust inside the sedimentation tank 44 can be discharged into the collection box 497.
