Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of dust treatment, and more specifically, to an intelligent wet treatment device for grinding dust. Background Art

[0002] The grinding of metal or stone products is a key process to improve the surface quality through physical grinding means. Its core purpose is to eliminate surface defects (such as scratches, burrs, and oxide scales) and improve the smoothness. At the same time, by reducing the surface roughness, the corrosion resistance and mechanical properties of the material are enhanced. The process is usually divided into three stages: rough grinding (removing obvious defects), fine grinding (gradually refining the surface), and fine polishing (achieving a mirror effect). By precisely controlling the grinding force and abrasive grain size, both the processing accuracy and production efficiency are taken into account.

[0003] Currently, the traditional methods for treating grinding dust mainly include dry dust removal and wet dust removal. The dry treatment of grinding dust mainly realizes the purification of dust and gas through physical separation technologies, including filtration, cyclone, electrostatic, and mechanical methods. The dry treatment method has limitations such as low fine dust capture efficiency, easy generation of secondary dust, and high filter element loss. Grinding dust can cause harm to the human body and there is also a risk of combustion and explosion. The wet dust removal method uses the interaction between water and dust to make the dust settle or be adsorbed by water, thereby achieving the purpose of dust removal. Common wet dust removal equipment includes spray towers, water curtain dust collectors, etc. However, the existing wet dust removal devices have a low degree of intelligence. During wetting, the dust cannot be fully wetted and settled, and some dust will still escape into the air, and it may also cause damage to the grinding equipment due to moisture.

[0023] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0024] Such as Figures 1 to 8As shown, an embodiment in an embodiment of the present disclosure provides a smart processing device for wetting grinding dust, including a workbench 1. The workbench 1 has a cavity 2 inside, and the tabletop of the workbench 1 has several material dropping openings 101. The inside of the workbench 1 is divided into a material dropping area 201 and a dust treatment area 202 by a partition 3. The material dropping area 201 collects the tabletop dust through the material dropping openings 101 and introduces it into the dust treatment area 202 below where there is water through the communication port 301. Multiple water mist nozzles 4 are arranged at the bottom of the dust treatment area 202 to initially wet the falling dust. At the top, a baffle plate 5 and the water surface form a baffle channel 501 to achieve secondary wetting and ventilation. A plurality of baffle plates 5 are vertically arranged on the inner wall of the workbench 1, and a plurality of baffle plates 5 are horizontally spaced along the length direction of the partition 3 at the inner top of the dust treatment area 202. A baffle channel 501 is formed between the plurality of baffle plates 5, the water surface, and the bottom surface of the partition 3. The baffle channel 501 is used to wet the dust that has not been wetted by the water mist nozzles 4 again, and the baffle channel 501 is also used for ventilation.

[0025] For example, as Figure 1 shown, when grinding work is carried out, the dust generated by grinding will fall into the workbench 1 through the material dropping openings 101. Specifically, the tabletop dust enters the material dropping area 201 through the material dropping openings 101. At this time, the dust with a larger particle size will directly fall into the water body in the lower dust treatment area 202 through the communication port 301 of the partition 3 due to its own gravity, realizing rapid preliminary separation. And the tiny dust will enter the treatment area with the airflow through the communication port 301.

[0026] When the dust enters the communication port, it will be wetted by the water mist nozzles 4 located below the communication port 301. The spraying direction of the water mist nozzles 4 is from the rear side to the front side of the workbench 1. After the water mist nozzles 4 spray water, a horizontally placed water curtain is just formed below the communication port 301. The water mist nozzles 4 spray dense water mist, so that the dust particles collide with the droplets and agglomerate to form heavier droplet groups and settle into the water. The residual dust not captured by the water mist continues to rise with the airflow and enters the zigzag channel formed by the baffle plate 5, the water surface, and the bottom surface of the partition 3. In the baffle channel 501, the dust particles are secondarily purified through multi-stage collisions and water film adsorption driven by the airflow. The purified airflow is directly discharged, while ensuring smooth ventilation inside the equipment, and at the same time enters the next cycle process and is reused again. The entire treatment process effectively realizes the separation and purification of dust and materials through the three-stage collaborative action of gravity separation, atomization wetting, and baffle purification.

[0027] It should be noted that several water mist nozzles 4 are arranged at intervals in a rectangular array, so as to increase the spraying area. The water mist nozzle 4 sprays water in the form of fine water droplets by using pressure. When water enters the inside of the nozzle, through special nozzle structure designs, such as the swirl chamber and nozzle inside the nozzle, the water forms a rotating or dispersed state during the high-speed flow process, and finally sprays out in the form of mist from the nozzle. These water droplets have a large surface area and can fully contact the dust. Through various action mechanisms such as inertial collision, interception, and diffusion, the dust adheres to the water droplets.

[0028] In addition, it should be noted that the communication port 301 of this device is located at the center of the partition plate 3. As shown in the figure, several baffle plates 5 are divided into two groups and symmetrically installed on both sides of the communication port 301.

[0029] The intelligent treatment device for wetting grinding dust realizes the efficient separation of coarse-grained materials and fine dust through the combination of gravity separation and water seal structure, avoiding dust diffusion and environmental pollution; the dense atomization area formed by the water mist nozzle 4 can quickly wet the fine dust and reduce the dust concentration in the air; the multi-stage collision design of the baffle channel 501 further improves the purification efficiency and ensures the cleanliness of the discharged air flow; effectively prevents dust from spreading everywhere, reduces the risk of combustion and explosion, and improves the safety of the equipment. At the same time, it greatly reduces the flying of dust, reduces the inhalation amount of dust by the operator, and ensures the personal safety of the operator.

[0030] In some examples, the intelligent treatment device for wetting grinding dust further includes several baffle plates 6. Several baffle plates 6 are all vertically arranged on the bottom surface of the workbench 1, and several baffle plates 6 are all located in the dust treatment area 202; the top surfaces of several baffle plates 6 are all far from the bottom surface of the partition plate 3, and the heights of several baffle plates 6 gradually decrease in the direction from the communication port 301 to the direction away from the communication port 301. The baffle plate 6 is used to limit the water surface height. A strip-shaped groove is provided in the middle of the baffle plate 6 close to the communication port 301. The strip-shaped groove is located below the liquid level to ensure that the liquid levels on both sides of the baffle plate 6 are flat. The remaining baffle plates 6 are not provided with strip-shaped grooves.

[0031] For example, such as Figure 1As shown, the baffle 6 is made of the same material as the workbench 1. The baffle 6 is directly welded to the inner bottom surface of the workbench 1. Multiple groups of baffles 6 are vertically arranged on the bottom surface of the workbench 1 in the dust treatment area 202. There is a certain distance between the top surface of the baffle 6 and the bottom surface of the partition 3, forming a water level adjustment space. The height of each baffle 6 decreases in a gradient along the direction from the communication port 301 to the far end of the treatment area. By changing the height difference of the baffles 6, the control of the water surface height is achieved. When the water level exceeds the top surface of the baffle 6, the excess water body can overflow through the gaps between the baffles 6, thus forming a stable water seal layer at the bottom of the dust treatment area 202. This water level limiting structure can not only ensure the effective atomization space of the water mist nozzle 4, but also maintain the optimal treatment water level through dynamic adjustment. At the same time, it assists the baffle channel 501 to form a stable air flow path, improving the dust collection efficiency.

[0032] The baffle 6 can ensure that the dust falling from the communication port 301 is quickly wetted by atomization and then falls into the water, avoiding the influence of too high water surface on the ventilation of the baffle channel 501 and the secondary wetting function of the dust, or too low water surface being unable to fully capture the dust. It can also enhance the dust sedimentation effect, making the dust settle into the water more quickly and fully, and improving the removal rate.

[0033] Secondly, the baffle 6 can reduce the influence of water flow fluctuations, prevent the water flow from splashing onto the water mist nozzle 4 or the baffle 5, ensure its normal operation, and effectively prevent the untreated water from overflowing from the dust treatment area 202, avoiding pollution and damage to the surrounding environment.

[0034] In some examples, the workbench 1 has several sewage collection tanks 7. The sewage collection tanks 7 are located at the bottom of the dust treatment area 202, and each sewage collection tank 7 is located between two adjacent baffles 6.

[0035] For example, as Figure 1 and Figure 2 shown, the dust generated by grinding enters the blanking area 201 through the blanking port 101 on the tabletop of the workbench 1. Larger particle dust and tiny dust fall into the water in the dust treatment area 202 through the communication port 301 of the partition 3. The water mist nozzle 4 wets the incoming fine dust, making it settle to the water surface. Under the action of the water flow, the wetted dust flows with the water. Since each sewage collection tank 7 is located between two adjacent baffles 6, the water flow carries the dust into the sewage collection tank 7. The baffle 6 plays a role in guiding the water flow and intercepting impurities, enabling the dust to gradually accumulate in the sewage collection tank 7. As the device continues to operate, more and more dust is collected in the sewage collection tank 7, facilitating subsequent centralized cleaning to maintain the high-efficiency operation of the device and good dust treatment effect.

[0036] Through the above process, this intelligent grinding dust wetting treatment device can efficiently treat the dust generated by grinding, reducing the harm of dust to the environment and the health of operators.

[0037] In some examples, the intelligent wet treatment device for grinding dust also includes an air outlet hood 8. The air outlet hood 8 is arranged directly above the workbench 1 and is used to blow the dust on the surface of the workbench 1 into the blanking area 201 through the blanking port 101.

[0038] For example, as Figure 3 and Figure 4 shown, the intelligent wet treatment device for grinding dust is also equipped with an air outlet hood 8. The air outlet hood 8 is installed directly above the workbench 1. The main function of the air outlet hood 8 is to generate an air flow. With the help of the wind force, the dust generated by the grinding operation on the surface of the workbench 1 is blown into the blanking area 201 inside the workbench 1 through the distributed blanking ports 101 on the surface, thus starting the subsequent dust treatment process. It should be noted that a plurality of air holes 801 are arranged at intervals in a rectangular array on the surface of the air outlet hood 8 close to the workbench 1. In this way, at the air outlet of the air outlet hood 8, the air does not concentrate in the middle of the air outlet hood 8, but blows towards the surface of the workbench 1 more evenly and in a certain area, ensuring that the dust generated on the workbench 1 can be quickly blown into the blanking area 201 and avoiding dead corners. It should be noted that most of the dust can enter the communication port 301 in the confluence hood 8 under its own weight, and the remaining part of the dust will be blown onto the confluence hood under the action of the air outlet hood 8. Since the surface of the workbench 1 is a grille or mesh structure, it will also play a role in blocking the movement of the dust that has fallen into the confluence hood 9. Secondly, after the air holes 801 blow out air, due to the circulation of the gas inside the workbench 1, the communication port 301 can absorb dust into the workbench, realizing the situation of blowing from above and sucking from below. And during grinding, baffles can be installed at the edge of the surface of the workbench 1. Secondly, to improve the dust collection situation, it can be ensured that the grinding part is close to directly above the communication port 301 at all times.

[0039] The air outlet hood 8 is arranged directly above the workbench 1 and can actively generate a directional air flow. During the grinding operation, the generated dust will diffuse near the surface of the workbench 1. The air flow generated by the air outlet hood 8 can concentrate these dusts that are originally easy to disperse everywhere and blow them into the blanking area 201 through the blanking port 101. Compared with only relying on natural sedimentation or passive dust collection methods, it can collect dust more efficiently and greatly increase the proportion of dust entering the treatment process.

[0040] In some examples, the intelligent wet treatment device for grinding dust also includes a confluence hood 9. The confluence hood 9 is in the shape of an inverted frustum of a pyramid. The confluence hood 9 is arranged on the partition 3. The confluence hood 9 is buckled upside down in the blanking area 201. The top surface of the confluence hood 9 is directly in contact with the workbench 1. The opening area of the top surface of the confluence hood 9 is the same as the opening area of the top surface of the workbench 1. A confluence port is arranged in the middle of the confluence hood 9. The confluence hood 9 has a confluence port, and the confluence port is communicated with the communication port 301.

[0041] For example, as Figure 1As shown, when the air outlet hood 8 blows the grinding dust on the workbench 1 into the blanking area 201 through the blanking port 101, these dusts will enter the confluence hood 9 inverted in the blanking area 201. Since the confluence hood 9 is in the shape of an inverted frustum of a pyramid, the top surface of the confluence hood 9 directly abuts against the workbench 1, and the opening area of the top surface is the same as that of the top surface of the workbench 1, which ensures that the dust entering from the blanking port 101 can smoothly and unobstructedly enter the internal space of the confluence hood 9. The dust entering the confluence hood 9 gradually gathers inside it. The special inverted frustum shape of the confluence hood 9 makes the space gradually shrink from top to bottom, and this structure helps to effectively guide and concentrate the dust.

[0042] As more and more dust enters the confluence hood 9, the dust will flow along the inner wall of the confluence hood 9 towards the middle. During this process, the originally relatively scattered dust gradually gathers. A confluence port is provided in the middle of the confluence hood 9, and the confluence port is connected to the communication port 301 on the partition plate 3. When the dust gathers in the confluence hood 9 to a certain extent, it will flow through the confluence port towards the communication port 301. The confluence port plays a role in further converging and guiding the dust, enabling the dust to enter the lower dust treatment area 202 in a relatively concentrated state through the communication port 301, and making preparations for subsequent dust treatment links such as humidifying by the water mist nozzle 4 and secondary humidifying by the baffle 5.

[0043] Through the work of the confluence hood 9, the entire intelligent grinding dust humidifying treatment device can collect and transport dust more efficiently, enabling the dust to enter each treatment link orderly, thereby improving the overall dust treatment efficiency and effect of the device.

[0044] In some examples, the workbench 1 has a suspended matter discharge port 10, the suspended matter discharge port 10 is connected to the dust treatment area 202, and the suspended matter discharge port 10 is flush with the water surface. After passing through the baffle channel 501, the wetted tiny dust floats on the water surface until it drifts to the suspended matter discharge port 10 and is discharged through the action of the water flow at the suspended liquid discharge port; the workbench 1 also has a number of sewage discharge ports 701, each sewage discharge port 701 is connected to a sewage collection tank 7, and usually the sewage discharge ports are blocked and are only opened when cleaning is required. The intelligent grinding dust humidifying treatment device also includes a collection box 11, the collection box 11 is arranged outside the workbench 1, the collection box 11 is connected to both the suspended matter discharge port and a number of sewage discharge ports 701, and a dust removal cloth bag is installed in the collection box 11. The sludge discharged through the suspended matter discharge port 10 and the sewage discharge ports 701 will enter the dust removal cloth bag, and the water will flow out of the dust removal cloth bag.

[0045] For example, as Figure 1As shown, specifically, when the dust generated by grinding enters the blanking area 201 through the blanking port 101 of the workbench 1, and then enters the dust treatment area 202 through the communication port 301, after being humidified by the water mist nozzle 4 and secondary humidified by the baffle 5 and other treatment links, some of the wetted fine dust will float on the water surface. Since the suspended matter discharge port 10 of the workbench 1 is communicated with the dust treatment area 202 and is flush with the water surface, driven by the water flow, these fine dust floating on the water surface will gradually drift towards the suspended matter discharge port 10 and finally flow out through this discharge port.

[0046] Meanwhile, the sewage collection tank 7 at the bottom of the dust treatment area 202 continuously collects precipitated dust and other impurities during the operation of the device. The sewage collection tank 7 is in one-to-one correspondence and communication with the sewage discharge port 701 of the workbench 1, but during normal operation, the sewage discharge port 701 is in a blocked state. When a certain time is reached or the sewage collection tank 7 needs to be cleaned, the sewage discharge port 701 will be opened, and the accumulated sludge and other impurities in the sewage collection tank 7 will be discharged from the sewage discharge port 701.

[0047] A collection box 11 is arranged outside the workbench 1, which is communicated with the suspended matter discharge port 10 and each sewage discharge port 701. The suspension containing fine dust flowing out from the suspended matter discharge port 10 and the sludge discharged from the sewage discharge port 701 will both enter the collection box 11. The collection box 11 is equipped with a dust removal cloth bag. When the sludge and suspension enter, the dust removal cloth bag will intercept solid impurities such as sludge, and the water will flow out through the dust removal cloth bag, realizing solid-liquid separation, which is convenient for subsequent centralized treatment of solid waste and further recycling of water resources.

[0048] In some examples, the workbench 1 also has an air outlet 12, the air outlet 12 is communicated with the dust treatment area 202, the air outlet 12 is located at the end of the baffle channel 501 and far from the water surface. At this time, the discharged air is relatively clean because it has passed through the treatment of the baffle channel 501; the intelligent grinding dust humidification treatment device also includes a ventilation column 13, which is arranged outside the workbench 1. The ventilation column 13 is L-shaped and hollow inside for ventilation. A blower is installed at the inner bottom of the ventilation column 13. The blower is used to blow air towards the air outlet hood 8. One end of the ventilation column 13 is communicated with the air outlet hood 8, and one end of the exhaust pipe 14 is communicated with the air outlet 12 and the other end is communicated with the ventilation column 13. Since the air outlet hood 8 continuously blows air into the workbench 1 during operation, the air in the workbench 1 has a tendency to move towards the air outlet 12, and the air in the workbench 1 has been treated and is relatively clean, so it can be recycled.

[0049] For example, as Figure 1As shown, specifically, first, the fan located at the inner bottom of the ventilation column 13 starts to blow air towards the air outlet hood 8. The air outlet hood 8 is arranged directly above the workbench 1. Under the action of the fan's wind force, the dust generated by grinding on the surface of the workbench 1 is blown into the blanking area 201 through the blanking port 101 by the air outlet hood 8, starting the dust treatment process. After the dust enters the blanking area 201, it is collected by the confluence hood 9 and enters the dust treatment area 202 through the connection port 301. In the dust treatment area 202, the water mist nozzle 4 initially humidifies the dust, and the baffle plate 5 further performs secondary humidification and purification on the unhumidified dust.

[0050] The air becomes relatively clean after passing through the baffle channel 501. Since the air outlet 12 is connected to the dust treatment area 202 and is located at the end of the baffle channel 501 and away from the water surface, this clean air will move towards the air outlet 12. At the same time, because the air outlet hood 8 continuously blows air into the workbench 1, a trend of air movement from the air inlet end to the air outlet 12 is formed inside the workbench 1. Then, the clean air is discharged from the air outlet 12, enters the ventilation column 13 through the exhaust pipe 14. The ventilation column 13 is L-shaped and hollow inside, serving as a ventilation channel. The air entering the ventilation column 13 continues to circulate under the action of the fan, is transported to the air outlet hood 8 again, and then re-enters the workbench 1 to participate in the dust treatment process. In this way, the recycling of air within the device is achieved, which not only ensures continuous dust collection power but also avoids waste of clean air, improving the overall operating efficiency and environmental protection performance of the device.

[0051] In some examples, the workbench 1 also has a water outlet 15. The water outlet 15 is connected to the dust treatment area 202 and is located at the end of the baffle channel 501 and close to the water surface. The intelligent grinding dust humidification treatment device also includes a water delivery pipe 16. One end of the water delivery pipe 16 is connected to the water outlet 15, and the other end is connected to the water mist nozzle 4, which can also enable the recycled use of the treated water.

[0052] For example, as Figure 5 and Figure 6As shown, during the dust treatment process, when the dust generated by grinding enters the dust treatment area 202, it will successively go through treatment steps such as humidification by the water mist nozzles 4 and secondary humidification by the baffle plate 5. After treatment, the water in the dust treatment area 202 is in a relatively clean state (compared with the state containing a large amount of dust before treatment). Since the water outlet 15 of the workbench 1 is connected to the dust treatment area 202 and the water outlet 15 is located at the end of the baffle channel 501 and close to the water surface, this enables the treated water to flow out smoothly from the water outlet 15. The water pipe 16 connected between the water outlet 15 and the water mist nozzles 4 starts to play a role, and the treated water flowing out from the water outlet 15 will be conveyed to the water mist nozzles 4 through the water pipe 16. The treated water reaching the water mist nozzles 4 is sprayed out again in the form of water mist and participates in the humidification process of the newly entering dust in the dust treatment area 202. In this way, the recycling of water in the device is realized, the waste of water resources is reduced, the operating cost of the device is also reduced, and the environmental protection and economy of the entire intelligent grinding dust humidification treatment device are improved.

[0053] In some examples, the intelligent grinding dust humidification treatment device further includes a plurality of conical sleeves 17. The plurality of conical sleeves 17 are all arranged in the communication port 301. The plurality of conical sleeves 17 are concentrically arranged with the communication port 301. The diameters of the plurality of conical sleeves 17 gradually increase from inside to outside, and the taper of the plurality of conical sleeves 17 gradually decreases from inside to outside. The adjacent conical sleeves 17 form a material dispersion channel 1701. The material dispersion channel 1701 is used to disperse the dust connecting rod 18 entering the dust treatment area 202. The connecting rod 18 is arranged on the plurality of conical sleeves 17 along the radial direction of the conical sleeve 17, and both ends of the connecting rod 18 are arranged on the partition plate 3.

[0054] For example, as Figure 7 shown, when the air outlet hood 8 blows the grinding dust on the workbench 1 of the workbench 1 into the blanking area 201 through the blanking port 101, and the dust flows through the confluence port to the communication port 301 under the confluence action of the confluence hood 9, it will enter the plurality of concentrically arranged conical sleeves 17.

[0055] The diameters of these conical sleeves 17 gradually increase from inside to outside, and the taper gradually decreases from inside to outside. A material dispersion channel 1701 is formed between the adjacent conical sleeves 17. When the dust enters the communication port 301, it will flow downward through these material dispersion channels 1701. Since the sizes and shapes of the respective material dispersion channels 1701 are different, when the dust passes through the material dispersion channels 1701, it will be dispersed. The originally relatively concentrated dust flow can be more evenly distributed into the lower dust treatment area 202 after passing through different material dispersion channels 1701.

[0056] The connecting rod 18 is arranged radially on a plurality of conical sleeves 17 along the radial direction of the conical sleeve 17, and both ends are fixed on the partition plate 3, playing a role in stabilizing the conical sleeve 17. During the process of dust passing through the communication port 301 and the bulk material channel 1701, the connecting rod 18 ensures the stable position of each conical sleeve 17, and will not be displaced or shaken due to factors such as the impact of dust, ensuring the structural integrity and stability of the bulk material channel 1701, so as to continuously and effectively disperse the dust entering the dust treatment area 202.

[0057] After being dispersed by the conical sleeve 17 and the bulk material channel 1701, the dust can come into fuller contact with the water mist sprayed by the water mist nozzle 4 in the dust treatment area 202 more widely, improving the efficiency of subsequent dust humidification and treatment, and enabling the entire intelligent wet treatment device for grinding dust to operate more efficiently.

[0058] In some examples, the connecting rod 18 has an installation groove 1801, and the connecting rod 18 further includes a plurality of elastic members 19. The plurality of elastic members 19 are arranged at intervals in the installation groove 1801, and the end of the connecting rod 18 is arranged on the partition plate 3 by connecting the elastic members 19.

[0059] For example, as Figure 8 shown, when the device starts to operate, the dust enters the blanking area 201 through the blanking port 101 of the workbench 1, and then enters the dust treatment area 202 through the communication port 301. During this process, a plurality of conical sleeves 17 arranged in the communication port 301 rely on the connecting rod 18 to stabilize their positions. The end of the connecting rod 18 is connected to the partition plate 3 through the elastic member 19, and the elastic member 19 is in a relatively stable state, providing stable support for the conical sleeve 17, ensuring that the bulk material channel 1701 formed by adjacent conical sleeves 17 can normally play the role of dispersing dust, and enabling the dust to enter the dust treatment area 202 evenly.

[0060] During the operation of the device, since the operator works directly on the tabletop of the workbench 1, the blockage of the workpiece being polished or the arm at this time will affect the wind direction. Due to the actions of the operator, including the actions of the arm and the blockage of the flipped workpiece, the conical sleeve 17 will vibrate or be impacted under the action of the wind direction at this time. When the vibration or impact is transmitted to the connecting rod 18, the connecting rod 18 will conduct the force to the elastic member 19 in the installation groove 1801. Since the elastic member 19 has the ability of elastic deformation, they will perform corresponding telescopic deformations according to the magnitude and direction of the vibration or impact.

[0061] When being vibrated, the elastic member 19 will undergo bending deformation, ensuring that the conical sleeve 17 can increase the vibration effect under the action of the elastic member 19 in a vibrating environment, further improving the dispersion effect.

[0062] In summary, after the dust enters the blanking port 101, it is accelerated by the confluence cover 9 and then dispersed and falls through the conical sleeve 17 of the communication port 301. After being initially humidified by the water mist, it enters the baffle channel 501, and secondary purification is completed during the collision between the air flow and the water surface. The purified air is discharged from the air outlet 12, and the dust-containing sewage is recycled after precipitation. The sludge and floating substances are collected through the sewage outlet 701 and the suspended matter outlet 10 respectively. Through multi-stage humidification, gravity sedimentation, air flow guidance and water circulation technologies, this device achieves a dust removal efficiency of more than 98%, and at the same time, the water saving rate reaches 70%. It has a compact structure and is convenient to maintain, and is applicable to the grinding operation scenarios of various metal and non-metal materials, with significant environmental and economic benefits.
