Description

Technical Field

[0001] This disclosure relates to the field of desulfurization equipment technology, and more specifically, to an absorption tower. Background Technology

[0002] As the core equipment of the desulfurization system, the support beams of the absorption tower are exposed to a complex corrosive environment with high concentrations of sulfur dioxide, chloride ions, and slurry erosion for a long time. This makes them prone to leakage, breakage, and safety problems such as beam collapse and shutdown. Utility Model Content

[0003] The purpose of this disclosure is to provide an absorption tower that effectively protects the supporting beam by setting up a protective structure, thereby at least partially solving the above-mentioned technical problems.

[0004] To achieve the above objectives, a first aspect of this disclosure provides an absorption tower, comprising: tray; Support beams; and The protective structure includes a protective shell, a first protective layer, and a second protective layer. The first protective layer is connected to the support beam and covers the circumferential outer wall of the support beam. The second protective layer covers the first protective layer. The protective shell is placed over the top of the second protective layer from above. The protective shell is at least partially located between the second protective layer and the tray. The tray is supported on the protective shell.

[0005] Optionally, the second protective layer includes a flexible protective layer.

[0006] Optionally, the flexible protective layer comprises a modified polytetrafluoroethylene fiber fabric, which is wound around the second protective layer.

[0007] Optionally, the first protective layer includes glass flakes; and / or, the thickness of the first protective layer is 48mm to 52mm; and / or, the number of the first protective layers is 4.

[0008] Optionally, the first protective layer is connected to the support beam by adhesive.

[0009] Optionally, the thickness of the putty is 2.3mm to 2.7mm.

[0010] Optionally, the protective structure further includes a gasket located between the second protective layer and the protective housing.

[0011] Optionally, the protective structure includes a U-shaped fastener connected to the tray via a connector, and the support beam and the protective structure pass through the inside of the U-shaped fastener.

[0012] Optionally, the protective cover is constructed in an inverted U-shape to cover the supporting beam.

[0013] Optionally, the first protective layer comprises glass flakes.

[0014] Optionally, the absorption tower further includes a tower body, and the tray, the support beam, and the protective structure are all disposed in the tower body, with the support beam connected to the tower body.

[0015] Through the above technical solution, by setting a first protective layer and a second protective layer covering the outer circumferential wall of the support beam, and then covering the second protective layer with a protective shell, a multi-level protection is formed to effectively isolate corrosive media and mechanical wear, preventing the corrosive media inside the absorption tower from directly eroding the support beam, and blocking the seepage path and gaps on the surface of the support beam, thereby preventing corrosive media from corroding the support beam through gaps or seepage paths. The protective shell between the tray and the support beam prevents the tray from directly bearing load and rubbing against the protective structure and support beam. By distributing the tray load and reducing stress concentration and local friction, the safety and overall structural stability can be improved. Furthermore, through the above structural design, the protective shell or protective layer can be maintained and replaced without disassembling the support beam. Therefore, the absorption tower provided by this disclosure has greater reliability and safety in use.

[0016] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0017] The accompanying drawings are provided to further illustrate the present disclosure and form part of the specification. They are used together with the following detailed description to explain the present disclosure, but do not constitute a limitation thereof. In the drawings: Figure 1 This is a cross-sectional structural diagram of the absorption tower provided in an exemplary embodiment of this disclosure, wherein the tower body and redundant structures have been removed, and only the tray, support beam and protective structure are shown.

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0021] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" generally refer to upper, lower, left, and right relative to the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of the corresponding components. Furthermore, the terms "first" and "second" used in this disclosure are for distinguishing one element from another and do not have sequential or importance. In addition, when the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0022] according to Figure 1 As shown, in a first aspect of this disclosure, an absorption tower is provided. The absorption tower may include a tray 2, a support beam 1, and a protective structure. The protective structure may include a protective cover 3, a first protective layer 4, and a second protective layer 5. The first protective layer 4 is connected to the support beam 1 and covers the circumferential outer wall surface of the support beam 1. The second protective layer 5 covers the first protective layer 4. The protective cover 3 is positioned above the second protective layer 5 and is located at least partially between the second protective layer 5 and the tray 2. The tray 2 is supported on the protective cover 3.

[0023] Through the above technical solution, by setting a first protective layer 4 on the circumferential outer wall of the support beam 1 and a second protective layer 5 covering the first protective layer 4, and covering the second protective layer 5 with a protective shell 3, a multi-level protection is formed to effectively isolate corrosive media and mechanical wear, avoid the direct erosion of the support beam 1 by the corrosive media in the absorption tower, and block the seepage path and gaps on the surface of the support beam 1, thereby preventing the corrosive media from corroding the support beam 1 through gaps or seepage paths and reducing the risk of pitting corrosion. The protective shell 3 is set between the tray 2 and the support beam 1 to avoid the direct pressure and friction of the tray 2 on the protective structure and the support beam 1. By dispersing the load of the tray 2 and reducing stress concentration and local friction, the safety and overall structural stability can be improved. In addition, through the above structural design, the protective shell 3 or the protective layer can be maintained and replaced without disassembling the support beam 1. For example, the protective structure on the support beam 1 can be replaced and maintained by only disassembling the tray 2.

[0024] The protective structure may also include a gasket 6 located between the second protective layer 5 and the protective shell 3 to prevent the protective shell 3 from directly contacting the second protective layer 5 and to mitigate the impact of external shocks and vibrations.

[0025] The gasket 6 can be an asbestos gasket 6 or a flexible graphite gasket 6. This disclosure is not limited thereto.

[0026] For example, the first protective layer 4 may include glass flakes, which can be connected to the support beam 1 by putty. In the processing, it is necessary to ensure that the circumferential outer wall surface of the support beam 1 is kept clean, and then a primer (e.g., vinyl ester resin) is applied. After the primer is applied, putty mixed with glass flakes is applied to the circumferential outer wall surface of the support beam 1 in layers. For example, the thickness of the first layer of putty can be 1 mm. After a period of time, putty is applied again. After two or more layers of application, the thickness of the putty is until it meets the preset value.

[0027] The preset thickness of the putty can be 2.3mm to 2.7mm, for example, the thickness of the putty can be 2.4mm, 2.5mm, or 2.6mm. The putty can be made of the same material as the primer to ensure bonding stability. This disclosure does not impose specific limitations in this regard.

[0028] In some implementable embodiments, the thickness of the first protective layer 4 can be 48 mm to 52 mm to improve protective strength. For example, the thickness of the first protective layer 4 can be 49 mm, 50 mm, or 51 mm. This disclosure does not specifically limit this.

[0029] In addition, the first protective layer 4 can be four layers to increase the protective strength, improve the impact resistance and corrosion threshold, and at the same time, reduce the porosity to prevent corrosive media from entering through the pores and corroding the support beam 1.

[0030] The thickness of the four first protective layers 4 can be 49mm, 50mm, or 51mm, and the thickness of each first protective layer 4 can be the same. This disclosure does not impose specific limitations on this.

[0031] In some feasible embodiments, the second protective layer 5 may include a flexible protective layer, which can reduce friction between the protective housing 3 and the second protective layer 5, reduce the risk of wear, and is inexpensive.

[0032] In some feasible embodiments, the second protective layer 5 may include a modified polytetrafluoroethylene (PTFE) fiber fabric. Exemplarily, the modified PTFE fiber fabric may be a modified PTFE fiber cloth. By incorporating the modified PTFE fiber fabric, the protective requirements of the absorption tower operating environment can be met; the modified PTFE fiber fabric possesses good tensile strength, temperature resistance, and good moisture resistance.

[0033] In some feasible ways, for example, refer to Figure 1As shown, the protective structure may include a U-shaped fastener 7, which is connected to the tray 2 via a connector 8. The support beam 1 and the protective structure pass through the inner side of the U-shaped fastener 7. In this way, the stability of the support beam 1 can be improved without drilling or welding. The U-shaped covering can increase the contact area with the support beam 1 to distribute the load transmitted by the tray 2, reduce stress concentration and local wear, and at the same time provide limiting and vibration-resistant constraints on the movement of the tray 2 relative to the support beam 1.

[0034] The U-shaped fastener 7 can be any suitable flexible fastener, such as a U-shaped strapping, to reduce friction between the U-shaped fastener 7 and the support beam 1.

[0035] The connector 8 can be constructed in any suitable manner. For example, the connector 8 may include a bolt and a nut, with the bolt sequentially passing through the U-shaped fastener and the tray 2 and connected to the nut on the other side. This disclosure is not limited thereto.

[0036] In some feasible ways, for example, refer to Figure 1 As shown, the protective cover 3 can be constructed as an inverted U-shape to cover the support beam 1. In this way, the U-shaped structure can provide effective protection for the top and sides of the support beam 1, blocking the scouring, splashing and particle impact of corrosive media, while reducing the friction and scratching of the tray 2 on the support beam 1 and / or the protective layer. In addition, the U-shaped structure can effectively realize drainage and diversion to avoid liquid accumulation on the top of the support beam 1.

[0037] The protective cover 3 can be welded to the support beam 1, thus the protective structure can effectively protect the gap between the protective cover 3 and the support beam 1. This disclosure is not limited thereto.

[0038] The protective cover 3 can be made of composite steel plate, and its thickness can be 2mm to 2.5mm, for example, 2.3mm, 2.4mm, or 2.5mm, which can improve its corrosion resistance. This disclosure is not limited thereto, and those skilled in the art can make adaptive adjustments according to actual needs.

[0039] In some feasible embodiments, the absorption tower may also include a tower body, with the tray 2, support beam 1, and protective structure all housed within the tower body, and the support beam 1 connected to the tower body.

[0040] For example, the inner wall of the tower body may be provided with grounding holes or slots for the support beam 1 to be inserted, and the tray 2 may be connected to the support beam 1 or the protective cover 3 covering the support beam 1 by bolt connection, so as to facilitate assembly and disassembly. This disclosure does not make specific limitations in this regard.

[0041] There can be multiple support beams 1, and multiple support beams 1 can be arranged at intervals in the tower body. For example, multiple support beams 1 can be arranged at intervals in the vertical direction, with each tray 2 corresponding to one support beam 1, and each support beam 1 is provided with a protective structure.

[0042] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0044] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
