Description

Technical Field

[0001] The present invention belongs to the technical field of spray dust removal, and in particular relates to a spray dust removal device for multiple scenarios. Background Art

[0002] Industrial production often generates large amounts of dust and solid particles. If not removed promptly, they can pollute the atmosphere. A spray dust removal system is a specialized air pollution control device that effectively removes large amounts of dust and solid particles from the air.

[0003] In the past, the practice of air dust removal was to use high-altitude spraying devices to spray clean water over a large area to remove dust. The disadvantage is that the clean water eventually falls on the ground or equipment, making the ground slippery and not conducive to continued operations. Falling on equipment will affect the safe operation of some live equipment.

[0004] In response to the shortcomings of previous practices, a tank-type spray dust removal device has been developed and designed. Its principle is to use a fan to introduce dust or solid particles into the spray tank along with the air. The air enters from the bottom of the spray tank and is discharged from the top of the spray tank. The spray head is installed on the top of the spray tank. In this way, the falling water mist or water droplets form convection with the rising air, removing dust or solid particles in the air. A filter is installed at the bottom of the tank, and the filtered water is recycled. The tank-type spray device has defects: First, the dust removal effect is generally poor by simply spraying. Second, if the filter is clogged or severely compacted, it needs to be stopped and replaced, and it cannot operate continuously. Summary of the Invention

[0005] In order to solve the problems in the background technology, the present invention provides a spray dust removal device for multiple scenarios. The present invention can be applied to multiple dust removal and solid particulate removal scenarios, and the dust removal rate of the present invention is higher.

[0006] The technical solution provided by the present invention is: a spray dust removal device for multiple scenes, including an outer cylinder, the side wall of the outer cylinder is provided with a dust suction hole; the inner side of the outer cylinder is sequentially provided with a cylinder one, a cylinder two and a cylinder three from the outside to the inside, the upper end of the cylinder one is sealed with the outer cylinder, the lower end of the cylinder one is free, an air inlet cavity is left between the cylinder one and the outer cylinder, dust and air enter the air inlet cavity from the dust suction hole, the lower end of the cylinder two is sealed with the outer cylinder, the upper end of the cylinder two is free, a spray cavity is left between the cylinder two and the cylinder one, the air in the air inlet cavity enters from the lower end of the spray cavity and flows out from the upper end of the spray cavity, and sprays The direction of the liquid is opposite, thereby forming strong convection and improving the dust removal rate; the upper end of the cylinder three is sealed and connected to the outer cylinder, and the lower end of the cylinder three is free. An acceleration chamber is left between the cylinder three and the cylinder two. The space of the acceleration chamber is smaller than the spray chamber. Therefore, when the gas passes through the acceleration chamber, the speed is significantly increased due to the narrowing of the space, and 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; the inner wall of the spray chamber is provided with a spray pipe, and nozzles are evenly installed on the spray pipe. A liquid dust removal filter layer is provided below the spray chamber. A mist dust removal filter layer is provided at the bottom, and the space inside the cylinder three is called a dehumidification chamber, in which a dehumidification filter layer is provided; partitions are evenly arranged along the circumferential direction in the acceleration chamber, one side of the partition is fixedly connected to the cylinder three, and the other side is fixedly connected to the cylinder two, and the space between adjacent partitions is called an acceleration port, and the upper edges of the partitions are spaced in the form of "two high and two low", so that the height of the upper edge of the acceleration port is in a state of "three low and one high", and sealing cover plates are evenly arranged along the circumferential direction above the acceleration chamber, and the positions of adjacent sealing cover plates correspond to the high port and the low port of the acceleration port respectively. Low mouth, a mounting ring is provided above the sealing cover plate, the sealing cover plate is elastically mounted on the mounting ring, the mounting ring is connected to a lifting device and driven by the lifting device; when the lifting device drives the mounting ring to drop one level, the sealing cover plate seals the acceleration port of the "high mouth", and the total volume of the acceleration chamber is reduced by one level; the lifting device drives the mounting ring to drop one level again, and the sealing cover plate seals part of the acceleration port of the "low mouth", leaving only the acceleration port of another part of the "low mouth". At this time, the actual use space of the acceleration chamber is reduced by one level again. Therefore, the actual use space of the acceleration chamber of this application can be adjusted.

[0007] A further technical solution is: there are two dehumidification filter layers, which are arranged one above and one below, and an extrusion plate is arranged between the two dehumidification filter layers. A push-pull rod is fixedly connected to the center of the extrusion plate, and the push-pull rod can move the extrusion plate upward or downward along the axis direction of the cylinder body, thereby realizing the squeezing of moisture in the two dehumidification filter layers respectively. A perforated plate is respectively arranged on the upper and lower sides of each dehumidification filter layer. The two perforated plates close to the extrusion plate in each dehumidification filter layer are movable perforated plates, and the two perforated plates away from the extrusion 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, and before entering the spray chamber, the air is filtered once through the gas dust removal filter layer to reduce the pressure of the spray dust removal.

[0009] A further technical solution is: the liquid dust removal filter layer includes a coarse filter layer and a fine filter layer, and a roller mounting sleeve is rotatably mounted on the cylinder body 2 above the liquid dust removal filter layer. The roller mounting sleeve is radially connected to a roller, and the axis of the roller is located in the radial direction of the roller mounting sleeve. The roller can rotate relative to the roller mounting sleeve. The coarse filter layer is an annular spiral structure, and the upper end of the coarse filter layer is fixedly connected to the roller. The roller gradually wraps the coarse filter layer on it during the revolution of the cylinder body 2 and its own rotation.

[0010] A further technical solution is: the upper edge height of the partition is consistent, so the upper edge height of the acceleration port is consistent; the upper end of the cylinder body 2 is evenly fixed with a mounting plate A along the circumferential direction, the outer wall of the cylinder body 3 is provided with a rotating ring, and the rotating ring can rotate relative to the cylinder body 3. The rotating ring is evenly fixed with a mounting plate B along the circumferential direction, and 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 the cylinder body 1 and the cylinder body 2 are both provided with sealed cavities, and the nozzles are evenly installed on the sealed cavities.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This application adds an acceleration chamber after the spray dust removal process. Dust not removed by the spray is accelerated in the acceleration chamber by the airflow from top to bottom. Gravity assists in accelerating the dust, and the dust is ultimately thrown onto the mist dust removal filter at an extremely high speed for removal. Compared with 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 dust suction holes is slow and the air intake volume is small, some of the acceleration ports are blocked to reduce the actual usable space of the acceleration chamber accordingly to ensure that the air can still reach the specified speed when passing through the acceleration chamber. When the air intake speed of the dust suction holes is faster 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 the present application is an annular spiral structure, which can be opened circle by circle. When the surface of the coarse filter layer is seriously clogged with dust, the roller can make two revolutions along the cylinder and rotate on its own to peel off one circle of the coarse filter layer with serious dust accumulation (the peeled circle of coarse filter layer is wound on the roller), exposing the next cleaner circle for continued filtering.

[0016] 4. The present application provides two dehumidification filter layers in the cylinder body 3, which are used to adsorb small water mist in the gas. When the amount of water adsorbed by the two dehumidification filter layers is large, the two dehumidification filter layers can be squeezed separately by moving the squeezing plate up and down, thereby squeezing out the water adsorbed in the two dehumidification filter layers, so that the two dehumidification filter layers can restore a certain dehumidification capacity.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

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

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

[0031] Inside the outer cylinder 1, cylinder 1 8, cylinder 2 10, and cylinder 3 12 are arranged in order from the outside to the inside. The upper end of cylinder 1 8 is sealed with the outer cylinder 1, while the lower end of cylinder 1 8 is free. An air inlet chamber 7 is left between cylinder 1 and the outer cylinder 1. Dust and air enter the air inlet chamber 7 through the dust suction hole 2. The lower end of cylinder 2 10 is sealed with the outer cylinder 1, while the upper end of cylinder 2 10 is free. A spray chamber 9 is left between cylinder 2 10 and cylinder 1 8. Air in the air inlet chamber 7 enters the spray chamber 9 from the lower end and flows out from the upper end, in the opposite direction of the spray liquid flow, thus forming strong convection, which helps to improve the dust removal rate. The upper end of cylinder body 3 12 is sealed with outer cylinder body 1 , while the lower end of cylinder body 3 12 is free. An acceleration chamber 11 is left between cylinder body 3 12 and cylinder body 2 10 . Acceleration chamber 11 is smaller than spray chamber 9 . Therefore, as the gas exiting spray chamber 9 passes through acceleration chamber 11 , its volume decreases, significantly increasing its velocity. Furthermore, the direction of acceleration is aligned with gravity, accelerating dust that is not removed by spraying and throwing it onto the filter layer below. This demonstrates that this embodiment not only has the ability to remove dust by spraying, but also accelerates the removal of dust. Compared to existing dust removal methods using only spraying, this embodiment achieves a higher dust removal rate and more ideal dust removal results.

[0032] The inner wall of the spray chamber 9 is provided with a spray pipe (not shown in the attached drawings), and nozzles 18 are evenly installed on the spray pipe. A liquid dust removal filter layer 13 is provided below the spray chamber 9. The dust or solid particles purified by the spray dust removal fall on 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 through a water circulation pipe 4. A circulating water pump 5 is provided on the water circulation pipe 4, thereby realizing the recycling of water. In this embodiment, as a replacement for the spray pipe: the cylinder 1 8 and the cylinder 2 10 are both provided with a sealed cavity, and the nozzles 18 are evenly installed on the sealed cavity. The advantage of setting the cylinder 1 8 and the cylinder 2 10 as sealed cavities is that the inner wall of the cylinder 1 8 and the outer wall of the cylinder 2 10 are smoother, which is more conducive to cleaning.

[0033] A mist dust removal filter layer 14 is provided below the acceleration chamber 11, and the space inside the cylinder body 12 is called a dehumidification chamber, in which a dehumidification filter layer 19 is provided.

[0034] like Figure 3 As shown, the said accelerating chamber 11 is evenly provided with partitions 25 along the circumferential direction. One side of the partition 25 is fixedly connected to the cylinder 3 12, and the other side is fixedly connected to the cylinder 2 10. The space between adjacent partitions 25 is called the accelerating port 1101. Figure 4 、 56, the upper edges of the partitions 25 are arranged in a "two high and two low" form, so that the upper edge height of the acceleration port 1101 is in a "three low and one high" state. The upper part of the acceleration chamber 11 is evenly provided with sealing cover plates 22 along the circumferential direction. The positions of adjacent sealing cover plates 22 correspond to the high port and the low port of the acceleration port 1101 respectively. A mounting ring 23 is provided above the sealing cover plates 22. The sealing cover plates 22 are elastically mounted on the mounting ring 23. The mounting ring 23 is connected to a lifting device 24 and is driven by the lifting device 24. When the lifting device 24 drives the mounting ring 23 to descend one level, as shown in FIG. Figure 5 As shown, the sealing cover plate 22 covers the acceleration port 1101 of the "high port", and the actual use space of the acceleration chamber 11 is reduced by one level; Figure 6 As shown, the lifting device 24 drives the mounting ring 23 to descend one level further, and the sealing cover plate 22 also covers part of the "low-mouth" acceleration port 1101, leaving only the other part of the "low-mouth" acceleration port 1101. At this time, the actual usable space of the acceleration chamber 11 is reduced by one level. After the actual usable space of the acceleration chamber 11 is reduced, the airflow velocity flowing through the acceleration chamber 11 is further increased when the air intake volume remains unchanged. When the air intake volume decreases, the airflow velocity flowing through the acceleration chamber 11 can remain unchanged due to the reduction in the actual usable space of the acceleration chamber 11. Therefore, the actual usable space of the acceleration chamber 11 of the present application can be adjusted. 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, and the sealing cover plate is slidably mounted on the short rod 26. The short rod 26 is mounted with a spring, and the two ends of the spring are respectively pressed against the sealing cover plate 22 and the mounting ring 23. Under the elastic force of the spring, the sealing cover plate 22 has a movement tendency away from the mounting ring 23.

[0036] like Figure 2As shown, there are two dehumidification filter layers 19, one above the other. The dehumidification filter layers 19 are soft dehumidification 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 dehumidification 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. The external driving force can be of various types and is not limited in this embodiment. The push-pull rod 21 can move the squeezing plate 20 upward or downward along the axis of the cylinder 3 12, thereby squeezing the moisture of the two dehumidification filter layers 19 respectively. A perforated plate is provided on the upper and lower sides of each dehumidification filter layer 19. The perforated plate is used to support each dehumidification filter layer 19. The two perforated plates close to the squeezing plate 20 in each dehumidification filter layer 19 are movable perforated plates, and the two perforated plates away from the squeezing plate 20 are fixed perforated plates. When the detection finds that the wind resistance through the dehumidification filter layer 19 is high, it means that the amount of water adsorbed on the dehumidification filter layer 19 is large. At this time, the dehumidification filter layer 19 needs to be squeezed. The method is to first move the squeezing plate 20 upwards. The squeezing plate 20 reaches the lower perforated plate of the upper dehumidification filter layer 19. Since the plate is movable, the plate is lifted up and squeezes the upper dehumidification filter layer 19 upwards together until the water is squeezed into place; then move the squeezing plate 20 downwards. The squeezing plate 20 reaches the upper perforated plate of the lower dehumidification filter layer 19. Since the plate is also movable, the plate is pressed and squeezes the lower dehumidification filter layer 19 downwards together until the water is squeezed into place. At this time, the two dehumidification filter layers 19 have restored a certain degree of dehumidification capacity.

[0037] A gas dust removal filter layer 17 is provided at the lower portion of the air inlet chamber 7. Before entering the spray chamber 9, the air is filtered once through the gas dust removal filter layer 17 to reduce the pressure of the 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, and a roller mounting sleeve 15 is rotatably mounted on the cylinder 2 10 above the liquid dust removal filter layer 13. A roller 16 is connected to the radial direction of the roller mounting sleeve 15, and the axis of the roller 16 is located in the radial direction of the roller mounting sleeve 15. The roller 16 can rotate relative to the roller mounting sleeve 15. The coarse filter layer is an annular spiral structure, and the upper end of the coarse filter layer is fixedly connected to the roller 16. When the surface of the coarse filter layer is seriously clogged with dust, the roller 16 gradually winds the coarse filter layer thereon during the revolution along the cylinder 2 10 and its own rotation, so as to uncover the coarse filter layer with serious dust accumulation (the uncovered circle of coarse filter layer is wound on the roller 16), exposing the cleaner next circle for continued filtration.

[0039] Example 2: Refer to the attached Figure 8-10 shown.

[0040] Unlike the first embodiment, the top edges of the partitions 25 in this embodiment are uniformly high, and thus the top edges of the acceleration port 1101 are uniformly high. Mounting plates A27 are uniformly fixed along the circumference of the upper end of the second cylinder 10. A rotating ring 29 is mounted on the outer wall of the third cylinder 12, which is rotatable relative to the third cylinder 12. Mounting plates B30 are uniformly fixed along the circumference of the rotating ring 29. The number of mounting plates B30 is the same as the number of mounting plates A27. An elastic sealing plate 31 is interposed between each mounting plate B30 and the corresponding mounting plate A27, sealing the upper end of the acceleration port 1101. To change the actual usable space of the acceleration chamber 11, simply rotate the rotating ring 29 to cover / open a portion of the acceleration port 1101 using the elastic sealing plate 31.

[0041] The rotating ring 29 has teeth on its exterior, and the rotation is driven by the driving teeth 28 , which are driven by external power. This embodiment does not limit the specific structure of the external power.

[0042] As shown in the above two embodiments, the present invention not only removes dust by spraying, but also accelerates dust removal by passing dust that is not removed by spraying through the acceleration chamber 11, thereby achieving a higher dust removal rate. The actual usable space of the acceleration chamber 11 of the present invention can be changed, so the amount of air intake does not affect the normal use of the accelerated dust removal. The present application also allows the online removal of the heavily contaminated coarse filter layer, exposing the cleaner next layer for continued filtration.
