Description

Technical Field

[0001] The utility model relates to the technical field of packed towers, in particular to a large flux packing for packed towers. Background Art

[0002] Coke oven gas contains hydrogen sulfide. The desulfurization tower for removing hydrogen sulfide by oxidation method usually adopts random rosette fillers or straight-through heavy ring fillers.

[0003] However, the above-mentioned fillers all have certain defects: since the desulfurization liquid contains a certain amount of sulfur foam, coke powder and other particulate impurities in the production process, the rosette fillers are often blocked and difficult to clean.

[0004] However, due to its structural reasons, the straight-through connecting ring cannot achieve sufficient and effective contact between gas and liquid, reducing the gas-liquid mass transfer area; on the other hand, the liquid film surface on the filler surface is updated slowly, affecting the gas-liquid mass transfer efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a large-flux filler for a packed tower, which has a large filler flux and can effectively avoid clogging by impurities.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A large flux packing for a packing tower, the packing is a regular packing composed of a plurality of packing sheets placed parallel to each other in the packing tower; the packing sheets are corrugated plate packing sheets, and the corrugation direction of each corrugated plate packing sheet is perpendicular to the center line of the packing tower.

[0008] Furthermore, the corrugated shape of the corrugated plate filler sheet is wavy or triangular.

[0009] Furthermore, windows are intermittently provided at the wave crests of the corrugated plate filler sheet.

[0010] Furthermore, the opening is reversely stretched to the trough position of the corrugated plate filler sheet to form a local reverse corrugated structure.

[0011] Furthermore, the local reverse corrugated structure is in direct contact with adjacent corrugated plate filler sheets for spacing.

[0012] Furthermore, when installing the packing in the packing tower, the corrugated plate packing sheets of the upper and lower packing plates are installed by rotating 5° to 10°.

[0013] Furthermore, the corrugated plate filler sheet is made of metal, ceramic or plastic.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The corrugated plate packing sheets of the utility model are placed in parallel in the packing tower to form regular packing. The corrugation direction of each corrugated plate packing sheet is perpendicular to the center line of the packing tower, providing sufficient gas-liquid flow space, large packing flux, and effectively avoiding impurity clogging.

[0016] 2. The utility model has windows intermittently arranged at the crest of the corrugated plate packing sheet. The liquid flowing downward along the surface of the corrugated plate packing sheet under the action of weight will be in the form of a film at the window, and part of the liquid will be diverted to the other side of the corrugated plate packing sheet, increasing the turbulence of the liquid film of the gas-liquid phase, and the liquid film is updated faster, thereby improving the gas-liquid mass transfer efficiency and increasing the gas-liquid mass transfer area. The gas flow direction is improved, and the liquid film exchange is formed, which is conducive to the lateral diffusion of the gas phase and reduces the pressure loss.

[0017] 3. The local reverse corrugated structure of the utility model is in direct contact with the adjacent corrugated plate filler sheets, forming a stable spacing effect between adjacent corrugated plate filler sheets. The regular filler blocks composed of the corrugated plate filler sheets do not require spacing columns, have a simple structure, and are easy to assemble, thereby reducing costs.

[0032] The corrugated shape of the corrugated plate packing sheet is a wave shape or a triangle. In this embodiment, it is an isosceles triangle, and the shape and size of the crest 1 and the trough 2 are the same.

[0033] The corrugated plate packing sheet has a window 4 intermittently arranged at the crest 1. The side of the window 4 is rectangular. Due to the existence of the window 4 structure, the liquid flowing downward along the surface of the corrugated plate packing sheet under the action of weight will be in a thin film at the window 4, and part of the liquid will be diverted to the other side of the corrugated plate packing sheet, increasing the turbulence of the liquid film of the gas-liquid phase, and the liquid film will be updated faster, thereby improving the gas-liquid mass transfer efficiency and increasing the gas-liquid mass transfer area. Improving the gas flow direction, forming a liquid film exchange, is conducive to the lateral diffusion of the gas phase and reducing the pressure loss.

[0034] The opening 1 is stretched in the reverse direction to the position of the trough 2 of the corrugated plate filler sheet, forming a local reverse corrugated structure 3.

[0035] The local reverse corrugated structure 3 directly contacts the adjacent corrugated plate packing sheet, playing a role in stabilizing the spacing between adjacent corrugated plate packing sheets. The regular packing block composed of the corrugated plate packing sheets does not require spacing columns, has a simple structure, is easy to assemble, and has low cost.

[0036] When installing the packing in the packing tower, the corrugated plate packing sheets of the upper and lower packing plates are rotated 5° to 10° for installation.

[0037] Corrugated plate packing sheets are made of metal, ceramic or plastic.

[0038] The utility model provides sufficient gas-liquid flow space, has a large filler flux, and effectively avoids impurity blockage. It improves the gas flow direction, forms liquid film exchange, is conducive to the lateral diffusion of the gas phase, and reduces pressure loss. It has a simple structure, is easy to assemble, and has low cost.

[0039] The above description is only part of the specific implementation methods of the utility model, and the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and utility model concept of the utility model, which should be covered by the protection scope of the utility model.
