Description

Technical Field

[0001] This invention relates to the field of acid mist treatment technology in hot-dip galvanizing workshops, specifically to an acid mist neutralization treatment device for hot-dip galvanizing workshops. Background Technology

[0002] To provide efficient and long-lasting corrosion protection for steel substrates, hot-dip galvanizing is required. This process involves immersing the substrate in zinc at high temperatures to form a metallurgically bonded zinc layer. This layer provides both physical isolation and electrochemical sacrificial protection, effectively isolating the substrate from air, moisture, and corrosive media. This prevents the steel from rusting and corroding, extending its service life. The coating is firmly bonded, impact-resistant, and wear-resistant, allowing for long-term use in normal environments with low maintenance costs. Compared to methods such as painting and electroplating, this method offers more reliable corrosion protection and a higher overall cost-effectiveness, making it a commonly used key process for improving the durability and safety of steel components.

[0003] During hot-dip galvanizing, some acid residue remains on the surface of the substrate after the pickling process. When the substrate is immersed in the galvanizing bath, it generates a large amount of acid mist upon heating. Therefore, neutralization of the acid mist is necessary. Conventional acid mist neutralization devices are often packed towers. The acid mist passes through alkaline packing material in the tower, causing a neutralization reaction between the acidic components and the alkaline packing. However, during this neutralization reaction, water is formed. This water residue forms a water film within the alkaline packing, affecting its permeability and consequently hindering the passage of acid mist, thus impacting the acid mist treatment efficiency. Furthermore, water stains adhering to the surface of the alkaline packing affect the contact between the packing and the acid mist, resulting in poor acid mist treatment. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes an acid mist neutralization treatment device for hot-dip galvanizing workshops. This invention controls the rotation of alkaline packing as the acid mist passes through it, thereby allowing water stains on the alkaline packing and in the gaps to be promptly removed, thus improving both the efficiency and effectiveness of acid mist treatment.

[0010] Preferably, a liquid storage gap is left between the inner wall of the baffle and the outer wall of the outer mesh sleeve; annular strips are evenly distributed above and below the liquid storage gap; the annular strips are fixedly connected to the inner wall of the baffle.

[0011] Preferably, the outer wall of the toothed rod is rotatably connected to the hollowed-out disk; a plurality of spiral plates are fixedly connected to the lower surface of the hollowed-out disk; the plurality of spiral plates extend to the inner side of their respective outer mesh sleeves.

[0016] 2. Due to the rotation of the outer mesh sleeve, water stains inside the outer mesh sleeve will converge from the center of the alkaline packing towards the edge, forming a "water curtain" at the edge of the alkaline packing to block the overflow of acid mist, thereby allowing the acid mist to flow smoothly upward along the center of the alkaline packing.

The drain groove is away from the central shaft of the motor, that is, the drain groove faces the inner wall of the cylinder. Therefore, the liquid discharged from the drain groove will flow directly to the inner wall of the cylinder, avoiding the water stains thrown out by the rotation of the outer mesh sleeve from adhering to other adjacent outer mesh sleeves, causing the alkaline filler to become damp again.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 7 As shown, the present invention includes the following embodiments: Example 1: An acid mist neutralization treatment device for a hot-dip galvanizing workshop, comprising a cylindrical box 1 and support legs 11 at the bottom of the cylindrical box 1; a box cover 2 with an air outlet pipe 21 is sealed at the upper port of the cylindrical box 1; an air inlet pipe 12 with an air pump 13 is provided on the arc-shaped outer wall of the cylindrical box 1; an inner sleeve 3 is fixedly connected to the inner bottom wall of the cylindrical box 1; the air inlet pipe 12 extends to the inner side of the inner sleeve 3; the arc-shaped outer wall of the inner sleeve 3 and the inner wall of the cylindrical box 1 form a ring-shaped drainage gap 31; a drainage pipe 4 is provided downwardly connected to the drainage gap 31; the upper end of the inner sleeve 3... A lower turntable 5 with a lower plate hole 51 is rotatably and sealed to the upper turntable 5; the center of the lower surface of the lower turntable 5 is connected to the inner bottom wall of the cylinder 1 by a motor 52; the lower turntable 5 is rotatably connected to the cover 2 by an upper turntable 6 with an upper plate hole 61; the upper turntable 6 is rotatably and sealed to the inner wall of the cylinder 1; the cover 2, the upper turntable 6, and the lower turntable 5 are kept at a distance; an outer mesh sleeve 7 is connected between the upper plate hole 61 and the corresponding lower plate hole 51; the lower end of the outer mesh sleeve 7 is fixedly connected to a mesh plate 71; the outer mesh sleeve 7 is filled with alkaline filler.

[0023] In this embodiment, the drain pipe 4 is sealed with a drain chamber 41; the drain chamber 41 is provided with a lower drain hole 42 extending downwards; the drain chamber 41 is provided with an upper drain hole 43 extending upwards; the upper drain hole 43 is slidably connected to a float 44; the outer wall of the float 44 is provided with a vertical notch 441; the drain chamber 41 is movably connected to a float plug 45 fixed to the lower end of the float 44; the lower surface of the cylinder 1 is fixedly connected to a discharge connector 15 communicating with the inner side of the inner sleeve 3.

[0024] During hot-dip galvanizing, the substrate is immersed in the galvanizing bath and generates a large amount of acid mist upon heating. The acid mist is collected and guided to the air inlet pipe 12. The air pump 13 operates, creating suction in the air inlet pipe 12, allowing the acid mist to enter the inner sleeve 3. The acid mist then passes through the mesh tray 71 from bottom to top and enters the inner sleeve 7. There, it comes into contact with the alkaline filler on the inner side of the outer sleeve 7. The acidic components in the acid mist neutralize the alkaline components in the alkaline filler, producing salt and water. The water film remaining in the gaps of the alkaline filler on the inner side of the outer sleeve 7 affects the passage of the acid mist and the neutralization efficiency. Furthermore, the water stains adhering to the alkaline filler further impair the contact between the acid mist and the alkaline filler. Therefore, during the process of the acid mist passing through the alkaline filler on the inner side of the outer sleeve 7 from bottom to top… Motor 52 drives the lower turntable 5 to rotate. During the rotation of the lower turntable 5, multiple lower plate holes 51 will rotate. The lower plate holes 51 are connected to the outer mesh sleeve 7 through the corresponding upper plate holes 61. Therefore, during the rotation of the lower turntable 5, the outer mesh sleeve 7 and the upper turntable 6 will rotate around the motor 52. The outer mesh sleeve 7 will drive the alkaline packing inside to rotate around the motor 52. The water stains attached to the alkaline packing inside the outer mesh sleeve 7 will be thrown away under the action of centrifugal force. The water stains inside the outer mesh sleeve 7 will pass through the outer mesh sleeve 7 and be thrown onto the inner wall of the cylinder 1. The water on the inner wall of the cylinder 1 will eventually converge into the annular drainage gap 31. The water in the drainage gap 31 will pass through the notch 441 on the float 44 and enter the drainage chamber 41 through the upper drainage hole 43. As the amount of water in the drainage gap 31 increases, the float... The buoyancy of rod 44 and float 45 increases, causing float 45 to move upward and move away from the lower drain hole 42, thus opening the lower drain hole 42. The notch 441 extends to the upper surface of float 45, so float 45 does not block the upper drain hole 43. The liquid in the drain gap 31 flows away along the notch 441, upper drain hole 43, drain chamber 41, and lower drain hole 42. As the amount of water in the drain gap 31 decreases, the buoyancy of rod 44 and float 45 decreases, and float 45 moves downward to block the lower drain hole 42. This makes it difficult for the water remaining in the drain gap 31 to drain away, achieving the purpose of "sealing the mist" and preventing acid mist leakage. The drain connector 15 is normally closed and will only be closed when necessary. The chamber is only opened when cleaning is required. After being neutralized by the alkaline material inside the outer mesh sleeve 7, the acid mist flows out along the upper end of the outer mesh sleeve 7 and the upper plate hole 61. The neutralized gas is finally discharged along the gas outlet pipe 21. The cover 2 is detachably connected to the upper port of the cylinder 1 by bolts. When the alkaline packing inside the outer mesh sleeve 7 is exhausted, the alkaline packing can be replenished in time by opening the cover 2. During the acid mist neutralization process, the water film attached to the alkaline packing is promptly shaken off, increasing the contact effect between the alkaline packing and the acid mist, thereby improving the acid mist neutralization effect. In addition, the water stains remaining in the pores of the alkaline packing particles are shaken off, making it easier for the acid mist to pass through the granular alkaline packing, improving the acid mist permeability, and further improving the acid mist neutralization efficiency.Multiple lower plate holes 51 on the lower turntable 5 are evenly distributed around the center of the lower turntable 5. During the rotation of the lower turntable 5, multiple outer mesh sleeves 7 will rotate synchronously, thereby changing the position of the lower end of the multiple outer mesh sleeves 7 inside the inner sleeve 3. This causes the lower end of the outer mesh sleeves 7 to circulate closer to and away from the air intake pipe 12, allowing acid mist to disperse into the inner side of the outer mesh sleeves 7, thereby improving the acid mist neutralization effect. This invention improves the efficiency and effectiveness of acid mist treatment by controlling the rotation of the alkaline packing during the process of acid mist passing through it, thereby allowing water stains on the alkaline packing and in the gaps to be promptly removed.

[0025] Example 2: Multiple lower plate holes 51 are evenly distributed around the center of the lower turntable 5; the center of the lower surface of the box cover 2 is fixedly connected to the gear 23 by a toothed bar 22; the upper end of the outer mesh sleeve 7 passes through the upper plate hole 61 and the outer ring is fixedly connected to the toothed ring 72; multiple toothed rings 72 mesh with the same gear 23; the outer mesh sleeve 7 is rotatably and sealingly connected to the upper plate hole 61 and the lower plate hole 51.

[0026] In this embodiment, the inner walls of the upper plate hole 61 and the lower plate hole 51 are provided with annular anti-detachment grooves 62; annular anti-detachment rings 63 are rotatably sealed within the anti-detachment grooves 62; and the anti-detachment rings 63 are fixedly connected to the corresponding outer mesh sleeve 7.

[0027] During the rotation of motor 52, the lower turntable 5 is driven to rotate. This rotation causes multiple lower plate holes 51 to rotate around the center of the lower turntable 5. The lower plate holes 51 and the corresponding upper plate holes 61 are rotatably connected to the outer mesh sleeves 7. Therefore, the rotation of the lower turntable 5 causes multiple outer mesh sleeves 7 to rotate around motor 52. A gear ring 72 that meshes with gear 23 is fixed to the outer edge of the upper end of each outer mesh sleeve 7. Thus, the outer mesh sleeve 7 rotates on its own axis during its rotation around motor 52. This rotation, in turn, causes the alkaline filler inside the outer mesh sleeve 7 to rotate. The residual water stains are thrown off more quickly under the combined action of rotation and revolution, improving the dehydration effect of the alkaline packing and thus enhancing the neutralization effect and efficiency of acid mist. During the rotation of the outer mesh sleeve 7, the anti-detachment ring 63 will rotate within the anti-detachment groove 62, and the outer mesh sleeve 7 will not detach from the upper plate hole 61 and the lower plate hole 51 during the rotation. In this embodiment, due to the rotation of the outer mesh sleeve 7, the water stains inside the outer mesh sleeve 7 will converge from the center of the alkaline packing towards the edge, so that the edge of the alkaline packing will form a "water curtain" that blocks the overflow of acid mist, thereby allowing the acid mist to flow smoothly upward along the center of the alkaline packing.

[0028] Example 3: A retaining sleeve 8 is fitted on the outer wall of the outer mesh sleeve 7; a strip-shaped drainage groove 81 is provided on the outer wall of the retaining sleeve 8; the drainage groove 81 is away from the central shaft of the motor 52; the retaining sleeve 8 is fixedly connected to the upper surface of the lower turntable 5.

[0029] In this embodiment, a liquid storage gap 82 is left between the inner wall of the baffle 8 and the outer wall of the outer mesh sleeve 7; annular strips 83 are evenly distributed on the upper and lower sides of the liquid storage gap 82; the annular strips 83 are fixedly connected to the inner wall of the baffle 8.

[0030] During the rotation of the outer mesh sleeve 7, the alkaline packing inside the outer mesh sleeve 7 is subjected to centrifugal force, causing the water stains attached to the alkaline packing to be thrown out and pass through the outer mesh sleeve 7. A baffle sleeve 8 is fitted on the outside of the outer mesh sleeve 7, so the water stains inside the outer mesh sleeve 7 are thrown onto the inside of the baffle sleeve 8. The baffle sleeve 8 rotates with the rotation of the lower turntable 5, and the water stains on the inside of the baffle sleeve 8 are discharged along the drain trough 81 under the centrifugal force of the baffle sleeve 8 itself. The drain trough 81 is away from the central axis of the motor 52, that is, the drain trough 81 faces the inner wall of the cylinder 1, so the liquid discharged from the drain trough 81 flows directly into the inner wall of the cylinder 1. To prevent water stains from being thrown out by the rotation of the outer mesh sleeve 7 onto other adjacent outer mesh sleeves 7, thus avoiding secondary dampness of the alkaline packing, the inner wall of the baffle sleeve 8 is uniformly fixed with annular strips 83 along the vertical direction. Therefore, the annular strips 83 can spread the water stains in the baffle sleeve 8 in layers in the vertical direction, preventing the water stains from flowing down the wall and accumulating. This allows the liquid to be evenly distributed on the inner wall of the baffle sleeve 8, and then thrown out in time from the drain trough 81 by centrifugal force, preventing the accumulated liquid from flowing back to the lower part of the outer mesh sleeve 7, preventing the alkaline packing from getting damp again, and ensuring neutralization efficiency.

[0031] Example 4: The outer wall of the toothed rod 22 is rotatably connected to the hollowed-out disk 9; multiple spiral plates 91 are fixedly connected to the lower surface of the hollowed-out disk 9; the multiple spiral plates 91 extend to the inner side of their respective outer mesh sleeves 7.

[0032] In this embodiment, the inner mesh sleeve 74 is fixedly connected to the center of the upper surface of the mesh disk 71 by the inner mesh rod 73; the upper end of the inner mesh sleeve 74 is lower than the outer mesh sleeve 7; the spiral plate 91 is located between the inner wall of the outer mesh sleeve 7 and the outer side of the inner mesh sleeve 74.

[0033] During the rotation of the lower turntable 5, multiple outer mesh sleeves 7 will revolve around the motor 52. This revolve of the outer mesh sleeves 7 will cause the upper turntable 6 to rotate. The revolve of the outer mesh sleeves 7 will also cause the inner spiral plates 91 to rotate around the central axis of the motor 52. The spiral plates 91 will then cause the perforated disc 9 to rotate around the gear bar 22. With the gear ring 72 meshing with the gear 23, the outer mesh sleeves 7 will rotate. During this rotation, the outer mesh sleeves 7 will interact with the inner spiral plates 91, which will agitate the alkaline filler. Furthermore, the lower end of the outer mesh sleeve 7 is fixedly connected to the mesh disk 71, causing the outer mesh sleeve 7 to rotate. The rotation of the mesh disk 71 will then cause the inner mesh bar 73 and the inner mesh sleeve 74 to rotate. This creates interaction between the inner mesh sleeve 74, the outer mesh sleeve 7, and the spiral plates 91. During the relative rotation of the spiral plates 91, the alkaline filler in the gap between the outer mesh sleeves 7 and the inner mesh sleeve 74 will be directed towards... In the top-feeding process, alkaline packing material enters the inner mesh sleeve 74 from the outside, passing over its upper port. The alkaline packing material inside the inner mesh sleeve 74 flows from top to bottom and then flows from the lower port of the inner mesh sleeve 74 into the space between the inner and outer walls of the outer mesh sleeve 74. It continuously circulates and agitates with the rotation of the spiral plate 91, thus creating an up-and-down circulation flow within the outer mesh sleeve 7. This prevents local accumulation, caking, and clogging, maintaining a loose and breathable state and significantly improving acid mist penetration and neutralization contact area. The continuous tumbling of the spiral plate 91 further peels away the water film on the packing surface, and combined with centrifugal dehydration, water stains are removed more thoroughly. The inner mesh sleeve 74 effectively constrains the circulation path, preventing packing material agglomeration and outflow, ensuring that acid mist passes evenly through the reaction zone. Overall, this extends the effective service life of the packing material, maintains consistently high purification efficiency, and makes the device more reliable and extends maintenance cycles.

[0034] Example 5: The hollow disk 9 is in contact with the upper port of the outer mesh sleeve 7; the hollow disk 9 can block the alkaline filler inside the outer mesh sleeve 7; the hole density on the mesh disk 71 decreases as it moves away from the center of the mesh disk 71.

[0035] The perforated disc 9 can block the upper port of the outer mesh sleeve 7, thus preventing the alkaline packing inside the outer mesh sleeve 7 from flowing out from the upper port under the agitation of the spiral plate 91, thereby ensuring stable circulation of the alkaline packing inside the outer mesh sleeve 7. The holes on the mesh disc 71 decrease in size as they move away from the center of the mesh disc 71, resulting in a higher air intake near the center of the mesh disc 71 compared to the edge. The alkaline packing inside the outer mesh sleeve 7 has a lower moisture content near the center, allowing acid mist to enter more concentratedly from the central area of ​​the mesh disc 71 and preferentially and fully contact the alkaline packing in the central area, which has a lower moisture content and higher reactivity. The lower hole density and lower air intake at the edge of the mesh disc 71 can match the edge water curtain structure formed by the rotation of the outer mesh sleeve 7, preventing acid mist from short-circuiting through the edge area with higher moisture content. This ensures that the acid mist flows evenly upward along the center of the packing, extending the effective reaction path and contact time, and further improving the acid mist neutralization efficiency and purification effect.
