Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, and particularly relates to a structure for reducing the accumulation of slurry on the annular stiffeners of an absorption tower. Background Art

[0002] The conventional circumferential stiffeners of vertical desulfurization towers are H-shaped steel or T-shaped steel, and grooves will be formed on the upper side. Due to corrosion and other reasons, part of the slurry seeping out of the tower accumulates inside the grooves (see Figure 1 、 Figure 2 ), resulting in the corrosion of the stiffeners and further exacerbating the corrosion of the absorption tower wall. And it is very difficult to clean these positions on site. During long-term operation, the corrosion will seriously affect the safety of the absorption tower directly.

[0003] To solve this problem, in the prior art, a steel plate is added above the annular stiffeners of the absorption tower. In most cases, the slurry will not accumulate in the grooves. However, in this closed area, if there is a leak in the absorption tower wall, before the rust penetration of the steel stiffeners causes leakage, the leakage problem still cannot be detected (see Figure 3 、 Figure 4 ), which will also seriously affect the structural safety of the absorption tower.

[0026] The following will further describe the present utility model in detail in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0027] Embodiment 1

[0028] As Figures 5 to 6 shown, the purpose of the present utility model is to prevent or reduce the accumulation of slurry without affecting the structural safety of the absorption tower itself, and avoid the corrosion of the absorption tower wall by the externally accumulated slurry.

[0029] To achieve the above object, the present utility model provides the following technical solution: a structure for reducing the slurry accumulation on the annular stiffener of the absorption tower, wherein openings 3 are formed at certain intervals on the annular stiffener 2, so that the slurry cannot accumulate in the groove of the annular stiffener.

[0030] The openings can be formed at different angular positions, and the local structure of the openings is strengthened. In this way, it not only does not affect the structural safety of the absorption tower itself, but also can reduce the slurry accumulation.

[0031] The accumulation of slurry in the groove of the annular stiffener of the absorption tower, the corrosion of the annular stiffener of the absorption tower by the slurry during long-term operation, and even the corrosion of the absorption tower wall 1 directly threaten the safety of the absorption tower. If the structure for reducing the slurry accumulation on the annular stiffener of the absorption tower is adopted, it not only does not affect the structural safety of the absorption tower, and the slurry cannot accumulate in the groove for a long time, but also can directly observe the slurry accumulation and corrosion conditions of the annular stiffener.

[0032] The present utility model has a simple form, is convenient to install, has strong safety and practicability, and can be widely applied to the tower structure.

[0033] The present utility model provides a structure for reducing the slurry accumulation on the annular stiffener of the absorption tower. Openings are formed on the annular stiffener section steel according to a certain rule. The openings can be in various forms, such as round holes, waist-shaped holes, and a combination of large and small holes. A reinforcing cover plate 4 and a reinforcing rib plate 5 are attached below the holes with larger diameters to increase the local strength and stability at the positions of the large holes without affecting the overall safety of the annular stiffener section steel.

[0034] The present utility model will not cause damage to the structure of the absorption tower, and can completely solve the problem of the corrosion of the absorption tower wall caused by the long-term accumulation of slurry in the above-mentioned background technology, and can also observe the slurry accumulation situation and corrosion situation in the groove of the annular stiffener at any time.

[0035] The present utility model opens holes at multiple places on the annular stiffener of the absorption tower to reduce the slurry accumulation situation;

[0036] The opening form of the present utility model is not limited, and can be in various forms, such as round holes, waist-shaped holes, and a combination of large and small holes;

[0037] Preferably, according to the size of the hole diameter, a reinforcing cover plate and a reinforcing rib plate are added at the opening position.

[0038] The embodiments described above are only a part of the embodiments of the present utility model, rather than limiting the scope of use of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model, without making any creative labor but only making equivalent structural changes, fall within the scope of protection of the present utility model.

[0039] As described above, the present utility model can be preferably implemented.

[0040] As described above, it is only a preferred embodiment of the present utility model, rather than imposing any form of limitation on the present utility model. According to the technical essence of the present utility model, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present utility model still fall within the scope of protection of the technical solution of the present utility model.
