Description

Technical Field

[0001] This invention belongs to the field of spray dust removal technology, and in particular relates to a spray dust removal device for multiple scenarios. Background Technology

[0002] Large amounts of dust or solid particles are frequently generated in various industrial production scenarios. If not removed in time, these particles will pollute the atmosphere. Spray dust removal devices are specialized air pollution control equipment that can effectively remove large amounts of dust or solid particles from the air.

[0003] In the past, the method of air dust removal was to use high-altitude spraying devices to spray clean water over a large area. The drawbacks are that the clean water eventually falls on the ground or equipment. The ground becomes slippery, which is not conducive to continuing the work. The equipment may affect the safe operation of some electrical equipment.

[0004] To address the shortcomings of previous methods, a tank-type spray dust removal device has been developed. Its principle is to use a fan to introduce dust or solid particles into the spray tank along with the air. Air enters from the bottom of the tank and exits from the top. Spray heads are installed at the top of the tank, creating convection currents between the falling water mist or droplets and the rising air, removing dust or solid particles from the air. A filter screen is installed at the bottom of the tank, and the filtered water is recycled. However, the tank-type spray device has the following drawbacks: First, dust removal through spraying alone is generally ineffective. Second, if the filter screen becomes clogged or severely hardened, the machine needs to be shut down for replacement, preventing continuous operation. Summary of the Invention

[0005] To address the problems in the background art, the present invention provides a multi-scenario spray dust removal device. The present invention can be applied to multiple dust removal and solid particulate matter removal scenarios, and the dust removal rate of the present invention is higher.

[0006] The technical solution provided by this invention is: a multi-scenario spray dust removal device, including an outer cylinder with suction holes on its side wall; three cylinders are arranged sequentially from the outside to the inside of the outer cylinder, with the upper end of cylinder one sealed to the outer cylinder and the lower end of cylinder one free; an air inlet chamber is provided between cylinder one and the outer cylinder, through which dust and air enter the air inlet chamber from the suction holes; the lower end of cylinder two is sealed to the outer cylinder and the upper end of cylinder two free; a spray chamber is provided between cylinder two and cylinder one, through which air enters the spray chamber from the lower end and flows out from the upper end, spraying the dust. The liquid flows in opposite directions, creating strong convection and improving the dust removal rate. The upper end of cylinder three is sealed to the outer cylinder, while the lower end of cylinder three is free. An acceleration chamber is left between cylinder three and cylinder two. The space of the acceleration chamber is smaller than that of the spray chamber. Therefore, when the gas passes through the acceleration chamber, its speed is significantly increased due to the narrowing space. Moreover, the acceleration direction is the same as the direction of gravity, thus accelerating and throwing the dust that has not been removed by the spray onto the filter layer below. The inner wall of the spray chamber is equipped with a spray pipe, and spray nozzles are evenly installed on the spray pipe. A liquid dust removal filter layer is arranged below the spray chamber. The acceleration chamber... A mist dust removal filter layer is installed below. The space inside cylinder three is called the dehumidification chamber, and a dehumidification filter layer is installed inside the dehumidification chamber. Baffles are evenly arranged circumferentially inside the acceleration chamber. One side of the baffle is fixedly connected to cylinder three, and the other side is fixedly connected to cylinder two. The space between adjacent baffles is called the acceleration port. The upper edges of the baffles are arranged in a "two high, two low" pattern, resulting in a "three low, one high" height at the upper edge of the acceleration port. Sealing covers are evenly arranged circumferentially above the acceleration chamber, with the positions of adjacent sealing covers corresponding to the high and low points of the acceleration port, respectively. A mounting ring is provided above the sealing cover plate at the lower opening. The sealing cover plate is elastically mounted on the mounting ring, and the mounting ring is connected to a lifting device and driven by the lifting device. When the lifting device drives the mounting ring to descend one level, the sealing cover plate seals the acceleration port of the "high opening", and the total volume of the acceleration chamber decreases by one level. When the lifting device drives the mounting ring to descend another level, the sealing cover plate seals part of the acceleration port of the "low opening" as well, leaving only the acceleration port of the other part of the "low opening". At this time, the actual usable space of the acceleration chamber decreases by one level again. Therefore, the actual usable space of the acceleration chamber in this application is adjustable.

[0007] A further technical solution is as follows: There are two desiccant filter layers, one above the other, with a squeezing plate between them. A push-pull rod is fixedly connected to the center of the squeezing plate. The push-pull rod can move the squeezing plate up or down along the axis of the cylinder, thereby squeezing the moisture in the two desiccant filter layers respectively. A perforated plate is provided on the upper and lower sides of each desiccant filter layer. The two perforated plates in each desiccant filter layer that are closer to the squeezing plate are movable perforated plates, and the two perforated plates that are farther away from the squeezing plate are fixed perforated plates.

[0008] A further technical solution is that a gas dust removal filter layer is provided at the lower part of the air inlet chamber. Before entering the spray chamber, the air is filtered once by the gas dust removal filter layer to reduce the pressure of spray dust removal.

[0009] A further technical solution is as follows: the liquid dust removal filter layer includes a coarse filter layer and a fine filter layer. A roller mounting sleeve is rotatably mounted on the cylinder two above the liquid dust removal filter layer. A roller is connected radially to the roller mounting sleeve. The axis of the roller is located radially to the roller mounting sleeve. The roller can rotate relative to the roller mounting sleeve. The coarse filter layer has an annular spiral structure. The upper end of the coarse filter layer is fixedly connected to the roller. The roller gradually winds the coarse filter layer around the cylinder two as it revolves around the cylinder and rotates on its own axis.

[0010] A further technical solution is as follows: the upper edge of the partition plate is at a consistent height, thus the upper edge of the acceleration port is at a consistent height; mounting plates A are uniformly fixedly arranged circumferentially at the upper end of the second cylinder; a rotating ring is fitted on the outer wall of the third cylinder, the rotating ring can rotate relative to the third cylinder; mounting plates B are uniformly fixedly arranged circumferentially on the rotating ring, the number of mounting plates B is the same as the number of mounting plates A; an elastic sealing plate is arranged between each mounting plate B and the corresponding mounting plate A, and the elastic sealing plate covers the upper end of the acceleration port.

[0011] A further technical solution is that both cylinder one and cylinder two have sealed cavities, and the nozzles are evenly installed on the sealed cavities.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. This application adds an acceleration chamber after the spray dust removal process. Dust particles not removed by the spray are accelerated from top to bottom within the acceleration chamber by the airflow. Gravity further accelerates the dust, which is then thrown at extremely high speed onto the mist dust removal filter layer for removal. Compared to traditional simple spray dust removal devices, this application achieves a significantly higher dust removal rate.

[0014] 2. The actual usable space of the acceleration chamber in this application can be adjusted. When the air intake speed of the suction hole is slow and the air intake volume is small, part of the acceleration port is blocked to reduce the actual usable space of the acceleration chamber accordingly, so as to ensure that the gas can still reach the specified speed when passing through the acceleration chamber; when the air intake speed of the suction hole is fast and the air intake volume is large, all the acceleration ports are opened to maximize the actual usable space of the acceleration chamber.

[0015] 3. The coarse filter layer in the liquid dust removal filter layer of this application has an annular spiral structure, which can be opened one ring at a time. When the surface of the coarse filter layer is severely clogged by dust, the roller can rotate once around the cylinder and rotate on its own axis to peel off one ring of the heavily dusty coarse filter layer (the peeled ring of coarse filter layer is wrapped around the roller), exposing a cleaner next ring for continued filtration.

[0016] 4. This application provides two dehumidifying filter layers inside the cylinder. The dehumidifying filter layers are used to adsorb small water mists in the gas. When the two dehumidifying filter layers adsorb a large amount of water, the two dehumidifying filter layers can be squeezed by moving the extrusion plate up and down, thereby squeezing out the water adsorbed in the two dehumidifying filter layers and restoring a certain dehumidifying capacity to the two dehumidifying filter layers.

[0028] To enable those skilled in the art to better understand the present invention, 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0029] Example 1: Refer to Appendix Figure 1-7 .

[0030] This embodiment includes an outer cylinder 1, with dust suction holes 2 on the side wall of the outer cylinder 1, an exhaust port 3 at the upper end of the outer cylinder 1, and a water collection area 6 at the lower end of the outer cylinder 1. The exhaust port 3 is connected to a negative pressure fan, which draws air containing dust or solid particles into the outer cylinder 1 through negative pressure.

[0031] Inside the outer cylinder 1, from the outside in, are arranged cylinder 1 (8), cylinder 2 (10), and cylinder 3 (12). The upper end of cylinder 1 (8) is sealed to the outer cylinder 1, while the lower end of cylinder 1 (8) is free. An air inlet chamber 7 is provided between cylinder 1 (8) and the outer cylinder 1, through which dust and air enter. The lower end of cylinder 2 (10) is sealed to the outer cylinder 1, while the upper end of cylinder 2 (10) is free. A spray chamber 9 is provided between cylinder 2 (10) and cylinder 1 (8). Air from the air inlet chamber 7 enters from the lower end of the spray chamber 9 and exits from the upper end, flowing in the opposite direction to the spray liquid, thus creating strong convection and improving the dust removal rate. The upper end of cylinder 3 12 is sealed to the outer cylinder 1, while the lower end of cylinder 3 12 is free. An acceleration chamber 11 is provided between cylinder 3 12 and cylinder 2 10. The space of the acceleration chamber 11 is smaller than that of the spray chamber 9. Therefore, when the gas coming out of the spray chamber 9 passes through the acceleration chamber 11, its velocity increases significantly due to the reduced volume. Moreover, the acceleration direction is the same as the direction of gravity, thereby accelerating the dust that has not been removed by the spray to the filter layer below. It can be seen that this embodiment not only has the ability to remove dust by spray but also has the ability to accelerate the removal of dust. Compared with the existing simple spray dust removal, the dust removal rate is higher and the dust removal effect is more ideal.

[0032] The inner wall of the spray chamber 9 is equipped with a spray pipe (not shown in the attached drawings), and spray nozzles 18 are evenly installed on the spray pipe. A liquid dust removal filter layer 13 is located below the spray chamber 9. Dust or solid particles purified by the spray fall onto the liquid dust removal filter layer 13 and are filtered. The clean water then falls into the water collection area 6. The water collection area 6 is connected to the spray pipe via a water circulation pipe 4, and a circulating water pump 5 is installed on the water circulation pipe 4, thus achieving water recycling. In this embodiment, as an alternative to the spray pipe: both the first cylinder 8 and the second cylinder 10 have sealed cavities, and the spray nozzles 18 are evenly installed on these sealed cavities. The advantage of using sealed cavities for the first cylinder 8 and the second cylinder 10 is that the inner wall of the first cylinder 8 and the outer wall of the second cylinder 10 are smoother, which is more conducive to cleaning.

[0033] Below the acceleration chamber 11, a mist dust removal filter layer 14 is provided. The space inside the cylinder 12 is called the dehumidification chamber, and a dehumidification filter layer 19 is provided inside the dehumidification chamber.

[0034] like Figure 3 As shown, partitions 25 are evenly arranged circumferentially within the acceleration chamber 11. One side of each partition 25 is fixedly connected to the third cylinder 12, and the other side is fixedly connected to the second cylinder 10. The space between adjacent partitions 25 is called the acceleration port 1101. Figure 4 , 5As shown in Figure 6, the upper edge of the partition 25 is arranged in a "two high, two low" pattern, so that the upper edge of the acceleration port 1101 is in a "three low, one high" state. A sealing cover plate 22 is evenly arranged circumferentially above the acceleration chamber 11. The positions of adjacent sealing cover plates 22 correspond to the high and low openings of the acceleration port 1101, respectively. A mounting ring 23 is arranged above the sealing cover plate 22. The sealing cover plate 22 is elastically mounted on the mounting ring 23. The mounting ring 23 is connected to a lifting device 24 and driven by the lifting device 24. When the lifting device 24 drives the mounting ring 23 to descend one level, as... Figure 5 As shown, the sealing cover 22 seals the acceleration port 1101 of the "high opening", reducing the actual usable space of the acceleration chamber 11 by one level; as Figure 6 As shown, the lifting device 24 drives the mounting ring 23 to descend another level, and the sealing cover 22 also covers part of the "low-end" acceleration port 1101, leaving only the other part of the "low-end" acceleration port 1101. At this time, the actual usable space of the acceleration chamber 11 is reduced by another level. After the actual usable space of the acceleration chamber 11 is reduced, the airflow velocity through the acceleration chamber 11 is further increased when the air intake volume remains unchanged; when the air intake volume is reduced, the airflow velocity through the acceleration chamber 11 can remain unchanged because the actual usable space of the acceleration chamber 11 is reduced. Therefore, the actual usable space of the acceleration chamber 11 in this application is adjustable, and the purpose of adjusting the actual usable space is to adapt it to the size of the air intake volume.

[0035] The sealing cover plate 22 is elastically mounted on the mounting ring 23. The specific structure is as follows: a short rod 26 is provided corresponding to each sealing cover plate 22. One end of the short rod 26 is fixedly connected to the mounting ring 23. The sealing cover plate is slidably fitted on the short rod 26. A spring is fitted on the short rod 26. The two ends of the spring abut against the sealing cover plate 22 and the mounting ring 23 respectively. Under the elastic force of the spring, the sealing cover plate 22 has a tendency to move away from the mounting ring 23.

[0036] like Figure 2As shown, there are two desiccant filter layers 19, arranged one above the other. Each desiccant filter layer 19 is made of soft dehumidifying filter cotton. After absorbing a certain amount of water, the absorbed water can be squeezed out. A squeezing plate 20 is provided between the two desiccant filter layers 19. A push-pull rod 21 is fixedly connected to the center of the squeezing plate 20. The push-pull rod 21 is driven by an external driving force, which can be various and is not limited in this embodiment. The push-pull rod 21 can move the squeezing plate 20 upwards or downwards along the axis of the cylinder 12, thereby squeezing the water from the two desiccant filter layers 19 respectively. A perforated plate is provided on the upper and lower sides of each desiccant filter layer 19. The perforated plates support each desiccant filter layer 19. The two perforated plates closer to the squeezing plate 20 in each desiccant filter layer 19 are movable perforated plates, and the two perforated plates farther from the squeezing plate 20 are fixed perforated plates. When the air resistance through the desiccant filter layer 19 is found to be high, it indicates that a large amount of water has been adsorbed on the desiccant filter layer 19. In this case, the desiccant filter layer 19 needs to be squeezed. The procedure is as follows: First, move the squeezing plate 20 upwards until it reaches the lower perforated plate of the upper desiccant filter layer 19. Since this plate is movable, it is lifted up and squeezes the upper desiccant filter layer 19 upwards until the water is squeezed out. Next, move the squeezing plate 20 downwards until it reaches the upper perforated plate of the lower desiccant filter layer 19. Since this plate is also movable, it is pressed down and squeezes the lower desiccant filter layer 19 downwards until the water is squeezed out. At this point, both desiccant filter layers 19 regain a certain amount of desiccant removal capacity.

[0037] The lower part of the air inlet chamber 7 is provided with a gas dust removal filter layer 17. Before entering the spray chamber 9, the air is filtered once by the gas dust removal filter layer 17 to reduce the pressure of spray dust removal.

[0038] like Figure 2 and Figure 7 As shown, the liquid dust removal filter layer 13 includes a coarse filter layer and a fine filter layer. A roller mounting sleeve 15 is rotatably mounted on the cylinder 10 above the liquid dust removal filter layer 13. A roller 16 is connected radially to the roller mounting sleeve 15. The axis of the roller 16 is located radially to the roller mounting sleeve 15. The roller 16 can rotate relative to the roller mounting sleeve 15. The coarse filter layer has an annular spiral structure. The upper end of the coarse filter layer is fixedly connected to the roller 16. When the surface of the coarse filter layer is severely clogged with dust, the roller 16 gradually wraps the coarse filter layer around it during its revolution around the cylinder 10 and its own rotation. This achieves the removal of one ring of the heavily dusty coarse filter layer (the removed ring of coarse filter layer is wrapped around the roller 16), exposing a cleaner next ring for continued filtration.

[0039] Example 2: Refer to Appendix Figure 8-10 As shown.

[0040] Unlike Embodiment 1, the upper edge height of the partition 25 in this embodiment is uniform, therefore the upper edge height of the acceleration port 1101 is uniform. Mounting plates A27 are uniformly fixedly arranged circumferentially at the upper end of the second cylinder 10. A rotating ring 29 is fitted onto the outer wall of the third cylinder 12, allowing rotation relative to the third cylinder 12. Mounting plates B30 are uniformly fixedly arranged along the rotating ring 29, with the number of mounting plates B30 being the same as the number of mounting plates A27. An elastic sealing plate 31 is provided between each mounting plate B30 and its corresponding mounting plate A27, sealing the upper end of the acceleration port 1101. When it is necessary to change the actual usable space of the acceleration chamber 11, only the rotating ring 29 needs to be rotated, using the elastic sealing plate 31 to cover / open part of the acceleration port 1101.

[0041] The rotating ring 29 has teeth on its outside, and the rotation is driven by the drive teeth 28. The drive teeth 28 are driven by external power. In this embodiment, the specific structure of the external power is not limited.

[0042] As shown in the two embodiments above, the present invention does not simply remove dust through spraying; dust not removed by spraying is further accelerated through the acceleration chamber 11, thus achieving a higher dust removal rate. The actual usable space of the acceleration chamber 11 can be varied, therefore the amount of air intake does not affect the normal operation of the accelerated dust removal. Furthermore, this application allows for the online removal of the heavily contaminated coarse filter layer, exposing a cleaner next layer for continued filtration.
