Abstract
Description
Technical Field
[0001] This utility model relates to the field of acid separator technology, specifically to a wave-damping device for an acid separator. Background Technology
[0002] In sulfuric acid production systems, the uniformity of acid distribution has a significant impact on SO3 absorption rates. Currently, the most common acid distributors on the market are tubular and tubular-trough type. Tubular-trough acid distributors distribute sulfuric acid evenly across the tower cross-section by overflowing it from the distribution tank into the distribution pipes. During overflow, the stability of the liquid level within the distribution tank is crucial. Excessive fluctuations in the liquid level will affect the uniformity of flow in each distribution pipe at the same time point, leading to insufficient SO3 absorption. One existing solution for this problem in tubular-trough acid distributors is to increase the length of the distribution branch pipes, thereby increasing friction loss and reducing the flow velocity within the branch pipes to mitigate liquid level fluctuations in the distribution tank. However, this structure not only increases production costs but also has an ineffective effect on balancing the liquid level. When the acid pump's delivery volume fluctuates, the liquid level balance in the distribution tank is easily disrupted. Another method involves sealing both ends of the acid-discharging T-tube and leaving an opening at the bottom to increase resistance to acid flow and balance the fluctuations in the liquid level within the tank. While this structure effectively mitigates the fluctuations, it easily leads to the accumulation of acid sludge and broken ceramic rings within the pipe. Furthermore, the sealing of both ends of the T-tube makes cleaning and maintenance difficult and costly. Therefore, there is a current need to develop a device that can eliminate liquid level fluctuations within the tank and also filter and easily clean broken ceramic rings and acid sludge from the acid solution. Utility Model Content
[0003] In view of the above-mentioned technical deficiencies, the technical problem to be solved by this utility model is to provide a wave-damping device for an acid separator, which aims to solve the problems of liquid surface fluctuation caused by liquid impact and blockage of the acid separator tube caused by the accumulation of solid particles during the acid separation process.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a wave-damping device for an acid separator, comprising: a box body disposed in an acid separator tank, the box body comprising an outer box body and an inner box body disposed inside the outer box body; the outer box body is composed of a cover plate and side plates; the inner box body is composed of a top plate and end plates, the top plate and the two side end plates being drilled with filter holes; the inner box body is welded and fixed to the middle of the outer box body by the top plate and the side plates of the outer box body; the cover plate of the outer box body and the top plate of the inner box body have circular holes in their centers to facilitate the installation of acid separator branch pipes.
[0005] Furthermore, the total area of the filter holes on the top plate and both side end panels of the inner box is not less than twice the cross-sectional area of the acid distribution branch pipe;
[0006] Meanwhile, the filter holes on the top plate and the two side end panels are arranged in an alternating pattern;
[0007] Among them, the diameter of the filter holes in the middle part of the top plate is larger than that of the edge part;
[0008] The upper aperture of the filter holes on the end panel is smaller than the lower aperture.
[0009] Furthermore, guide rails are welded to the side panels of the outer casing to guide the end panels of the inner casing.
[0010] Furthermore, the cover plate of the outer casing and the two end panels of the inner casing are each provided with a pull rod hole on the same plane.
[0011] Furthermore, the two end panels of the inner casing are installed in the guide rails and move linearly in the vertical direction via the pull rods.
[0012] Furthermore, one end of each of the two pull rods passes through the pull rod hole and is fixed above the two end panels of the inner box, while the other end of each of the two pull rods is left at a distance from the cover plate of the outer box and a handle is welded thereon.
[0013] Furthermore, it also includes a limiting strip fixed to the bottom of the acid separation tank. The limiting strip is also closely attached to the outer side of the two end panels of the inner tank to prevent the end panels from shaking due to liquid impact.
[0014] Furthermore, it also includes:
[0015] The fixing rod is fixed at a predetermined distance above the connection point between the pull rod and the cover plate of the outer casing.
[0016] A pull rod locking device is fixed at the connection between the cover plate of the outer casing and the pull rod;
[0017] The pull rod locking device includes a base and a movable cover plate with a notch. The movable cover plate with the notch cooperates with the fixed rod. When the pull rod is pulled up, the movable cover plate with the notch is rotated so that its notch aligns with the fixed rod, and the pull rod is pulled up smoothly. When the pull rod does not need to be pulled up, the movable cover plate with the notch is rotated so that its notch is misaligned with the fixed rod, thereby fixing the pull rod and preventing the end panel from shaking due to liquid impact.
[0018] An acid separator employs a wave-damping device to reduce liquid level fluctuations within the acid separator tank.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. Holes are drilled on the top plate and side end panels of the inner tank. After the acid flows out from the acid distribution branch pipe into the wave damping device, it flows out from the filter holes on the top plate and end panels. Solid particles such as broken porcelain rings and acid sludge in the acid are blocked in the inner tank, reducing the solid particles in the acid distribution tank and avoiding acid distribution failure caused by solid particles clogging the acid distribution pipe.
[0021] 2. This device has low maintenance costs and high efficiency. It only requires periodically pulling the levers on both sides of the inner box upwards to remove accumulated solid particles such as broken porcelain rings and acid sludge. After cleaning, the device can be used again after the levers are reset.
[0022] 3. When the acid flows out from the top and end panels of the inner tank, it needs to overcome the resistance at the filter holes, which reduces the flow velocity at the outlet, minimizes the impact on the liquid surface, and makes it less likely to disrupt the original liquid surface balance, thus stabilizing the liquid surface. When the acid flows out from the top plate of the inner tank, it will generate an upward liquid column. The cover plate of the outer tank can effectively block the liquid column, prevent liquid splashing, and protect personnel safety. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a wave-damping device for an acid separator, comprising: a housing disposed within an acid separator tank 1, the housing including an outer housing 3 and an inner housing 4 disposed inside the outer housing 3; the outer housing 3 is composed of a cover plate 31 and side plates 32; the inner housing 4 is composed of a top plate 41 and end plates 42, the top plate 41 and the two end plates 42 having filter holes drilled in them; the inner housing 4 is welded and fixed to the middle of the outer housing 3 by the top plate 41 and the side plates 32 of the outer housing 3; the cover plate 31 of the outer housing 3 and the top plate 41 of the inner housing 4 have circular holes in their centers for easy installation of the acid separator branch pipe 2; the total area of the filter holes on the top plate 41 and the two end plates 42 of the inner housing 4 is not less than twice the cross-sectional area of the acid separator branch pipe 2; simultaneously, the filter holes on the top plate 41 and the two end plates 42... The arrangement is staggered; the diameter of the filter holes in the middle part of the top plate 41 is larger than that of the edge part; the diameter of the filter holes in the upper part of the end panel 42 is smaller than that of the lower part; the guide rail 33 is welded on the side plate 32 of the outer box 3 to guide the end panel 42 of the inner box 4; the cover plate 31 of the outer box 3 and the two end panels 42 of the inner box 4 are on the same plane and each has a pull rod hole 34; the two end panels 42 of the inner box 4 are installed in the guide rail 33 and move linearly in the vertical direction through the pull rod 5; one end of each of the two pull rods 5 passes through the pull rod hole 34 and is fixed above the two end panels 42 of the inner box 4, and the other end of each of the two pull rods 5 leaves a distance from the cover plate 31 of the outer box 3 and is welded with a handle.
[0032] Furthermore, to prevent the lower part of the end panel 42 from shaking due to liquid impact, thus preventing the effective accumulation of solid particles, two limiting strips are fixed to the bottom surface of the acid separation tank 1. These limiting strips are also tightly attached to the outer sides of the end panels 42 on both sides of the inner tank 4. Alternatively, to prevent the end panel 42 from shaking upwards due to liquid impact, thus preventing the effective accumulation of solid particles, such as... Figure 4 and Figure 5As shown, a fixing rod 51 and a pull rod locking device 6 are provided. Specifically, the fixing rod 51 is fixed at a predetermined distance above the connection between the pull rod 5 and the cover plate 31 of the outer casing 3; the pull rod locking device 6 is fixed at the connection between the cover plate 31 of the outer casing 3 and the pull rod 5. The pull rod locking device 6 includes a base 61 and a movable cover plate 62 with a notch. The movable cover plate 62 with the notch cooperates with the fixing rod 51. When the pull rod 5 is pulled up, the movable cover plate 62 with the notch is rotated so that its notch corresponds to the fixing rod 51, and the pull rod 5 is pulled up smoothly. When the pull rod 5 does not need to be pulled up, the movable cover plate 62 with the notch is rotated so that its notch is misaligned with the fixing rod 51, so that the pull rod 5 is fixed, which is used to prevent the end panel 42 from shaking due to liquid impact.
[0033] like Figure 3 As shown, this embodiment also provides an acid separator, which employs a wave-damping device to prevent liquid level fluctuations caused by liquid impact and blockage of the acid separator tube caused by the accumulation of solid particles during the acid separation process.
[0034] During operation, acid flows out from the acid distribution branch pipe 2 and enters the inner tank 4. Filter holes are drilled on the top plate 41 and end panel 42 of the inner tank 4. The total area of these filter holes is no less than twice the cross-sectional area of the acid distribution branch pipe 2 to ensure smooth liquid flow. The filter holes are arranged in a staggered manner to reduce turbulence and impact during liquid flow. The diameter of the middle part of the filter holes on the top plate 41 is larger than that of the edge part, and the diameter of the upper part of the filter holes on the end panel 42 is smaller than that of the lower part. This design helps to distribute the liquid evenly and further reduces local impact. The filtered acid flows out from the filter holes on the top plate 41 and end panel 42 of the inner tank 4 and enters the acid distribution tank 1. Solid particles in the inner tank 4 are intercepted by the filter holes and remain in the inner tank 4, reducing the amount of solid particles in the acid distribution tank 1 and avoiding acid distribution failure caused by solid particles clogging the acid distribution pipe. Specifically, the cover plate 31 of the outer tank 3 can effectively block the liquid column flowing out from the top plate 41 of the inner tank 4 to prevent liquid splashing and protect the safety of the operators.
[0035] Preferably, guide rails 33 are welded to the side plates 32 of the outer casing 3, and the end panels 42 of the inner casing 4 are installed in the guide rails 33 to ensure that the end panels 42 move in a straight line in the vertical direction, reducing the shaking caused by liquid impact; at the same time, limit strips are fixed to the bottom surface of the acid separation tank 1, and the limit strips are closely attached to the outer sides of the end panels 42 of the inner casing 4 to further prevent the end panels 42 from shaking and ensure the stability of the inner casing 4; when it is necessary to clean solid particles in the inner casing 4, the operator can lift the pull rod 5 through the handle on the cover plate 31 of the outer casing 3, wherein one end of the pull rod 5 is fixed above the end panels 42 of the inner casing 4, and the other end passes through the pull rod hole 34 on the cover plate 31 and... The welding handle is also included; preferably, it further includes a pull rod locking device 6, which includes a base 61 and a movable cover plate 62 with a notch. In normal operation, the notch of the movable cover plate 62 is misaligned with the fixed rod 51, and the pull rod 5 is fixed to prevent the end panel 42 from shaking. When it is necessary to lift the inner box 4, the operator rotates the movable cover plate 62 so that its notch aligns with the fixed rod 51, and the pull rod 5 can be pulled up smoothly to lift the inner box 4. After removing solid particles from the inner box 4, the pull rod 5 is reset, and the movable cover plate 62 is rotated again so that its notch is misaligned with the fixed rod 51, and the pull rod 5 is fixed, and the inner box 4 returns to normal operation.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
