Description

Technical Field

[0001] The utility model relates to the technical field of packing devices, in particular to a beam-type supporting plate and a packing tower. Background Art

[0002] The packed tower uses packing as the basic component for gas-liquid contact and mass transfer, and is a type of mass transfer equipment commonly used in chemical production. It is mainly composed of a cylindrical tower body and a support plate. The packing liquid stacked in the tower flows from top to bottom on the surface of the packing in a film-like manner, and the gas flows from bottom to top in a continuous phase with the liquid, and mass and heat transfer between the gas and liquid phases is carried out. The packing support device is mainly used to support the packing in the tower, and it needs to have sufficient hardness and strength.

[0003] In the prior art, in the process of treating industrial waste gas, it is necessary to use fillers to absorb and treat harmful substances contained in the waste gas. A filler support plate is installed at the bottom of the packing tower, and the fillers are placed on the support plate in a random or complete manner. The general filler support structure has a low opening rate, which will cause a high pressure when the gas passes through, thereby reducing the treatment efficiency of harmful gases.

[0004] Chinese utility model patent 202122524379.4 discloses a support plate, including a placement plate and a washing tower body, wherein the top outer wall of the placement plate is provided with a plurality of hump support plates, and the hump support plates are in a hump structure, and the plurality of hump support plates are spliced ​​and installed, and the top outer wall of the hump support plate is provided with a plurality of openings 1, and the bottom outer wall of the hump support plate is provided with a plurality of openings 2. The utility model can support and fix a plurality of hump support plates by providing a placement plate, and after the plurality of hump support plates are spliced ​​and installed, the overall structure is a circular structure. The contact effect between the exhaust gas and the filler can be improved.

[0005] However, the above support plate has the following disadvantages:

[0006] 1. The total area formed by the openings on the support plate is insufficient, resulting in low gas-liquid mass transfer and heat transfer efficiency;

[0007] 2. Multiple hump support plates are connected by bolts. The vibration in the packing tower can easily cause the bolt connection to loosen, which can seriously cause the nuts to fall off, the support plates to detach, and the packing to collapse.

[0008] 3. The thickness of the filler at the hump position on the hump support plate should be smaller than that at other positions. The upper and lower humps are always in a vertical direction, and the thick filler and the thin filler are also always in a vertical direction. As a result, the heat transfer at the thick position is insufficient, resulting in low efficiency. In addition, the thick position has a large weight, which is not conducive to the force balance of the tower wall. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings:

[0033] Example 1

[0034] As attached Figure 1 -Attached Figure 3 As shown, the utility model provides a beam-type support plate, which is horizontally arranged in a packing tower. The specific scheme is as follows:

[0035] The beam-type support plate 8 is wavy, including a crest portion 2, a trough portion 1 and a connecting portion 3. The crest portion 2 and the trough portion 1 are connected by the connecting portion 3. First air holes 5 are opened on the crest portion 2 and the trough portion 1. The porosity of the beam-type support plate 8 is greater than the porosity of the filler.

[0036] Since the opening ratio is greater than the porosity of the filler, the gas-liquid medium that passes through the first air holes 5 of the beam support plate 8 is greater than the gas-liquid medium that overflows from the pores of the filler, so that the gas-liquid medium can smoothly enter the filler through the air holes and ensure that the filler is quickly filled with the gas-liquid medium, greatly improving the efficiency of heat and mass transfer.

[0037] Furthermore, the first air holes 5 include round holes, elliptical holes, waist-shaped holes, and strip-shaped holes.

[0038] Furthermore, a second air hole 6 is formed on the connecting portion 3 .

[0039] Furthermore, the second air permeable hole 6 is a waist-shaped hole or a strip-shaped hole.

[0040] Since the first air holes 5 and the second air holes 6 are arranged in various styles such as the aforementioned round holes, elliptical holes, waist-shaped holes, strip holes, etc., the diameter of the hole, at least the short side of the hole can be reduced, so that the gas enters the packing layer from bottom to top, which is convenient for gas-liquid separation and full contact, and can reduce liquid flooding, thereby improving the gas passing efficiency and effectively intercepting the packing, and preventing the packing from leaking even if the packing is damaged into small pieces.

[0041] Furthermore, the crest portion 2 and the connecting portion 3 connected to the left and right sides form a trapezoidal structure, and the trough portion 1 and the connecting portion 3 connected to the left and right sides form an inverted trapezoidal structure.

[0042] Furthermore, it is characterized in that the crest part 2 and the trough part 1 are plate-shaped, which can make the filler contact well with the beam support plate 8, and the gas can smoothly enter the pores of the filler through the air holes.

[0043] Example 2

[0044] The difference from the first embodiment is that a concave groove 4 is provided on the trough portion 1 , and adjacent beam-type supporting plates 8 are connected via the concave groove 4 .

[0045] Furthermore, rivets 7 are used to fix adjacent beam support plates 8 and between the beam support plates 8 and the tower wall 9 of the packing tower.

[0046] Furthermore, the beam-type support plate 8 is made of stainless steel.

[0047] The riveting process is suitable for thin-wall connections and is also suitable for connections between various materials. At the same time, riveting has the advantages of not being easy to loosen, light weight, and high lightness. Furthermore, compared with the welding used in the existing support plate, riveting can also solve the problem of stress concentration. The welding process will cause the stress of the support plate to be concentrated on one line. Metal fatigue is very likely to occur near the weld, resulting in cracking, and this fatigue line is very difficult to locate, posing a safety hazard. The riveting process can disperse the stress to each riveting point. Second, rivets can provide better flexibility and adaptability. Different temperature and pressure changes will be experienced during the production process. These changes will cause the metal material to expand and contract with heat, that is, the metal expands when the temperature rises and contracts when the temperature drops. If welding is used, these changes will cause stress and deformation between the metals, and even cracking at the weld. Using rivets can avoid this situation because rivets can allow a certain degree of relative movement and adjustment between the metals, and the installation process of rivets is also relatively simple and fast.

[0048] In this embodiment, a plurality of adjacent beam-type support plates 8 are connected by concave grooves 4 and fixed by rivets 7, which effectively avoids loose connections and falling-off of connectors due to vibration. In addition, the beam-type support plates 8 are made of stainless steel, and the rivets 7 also have certain anti-corrosion properties, thereby improving the reliability of the connection.

[0049] Example 3

[0050] A packed tower adopts the beam-type support plate described in Example 1 or Example 2, wherein the upper and lower layers of the beam-type support plates 8 are installed at a 90° interval.

[0051] The thickness of the filler at the crest 2 on the beam support plate 8 is smaller than the thickness of the filler at the trough 1. If the crests or troughs of the upper and lower beam support plates are always in a vertical direction, the thicker fillers and the thinner fillers will also always be in a vertical direction. As a result, the heat transfer at the thicker position is insufficient, resulting in low efficiency. In addition, the weight of the filler at the thicker position is large, and the weight of the filler at the thinner position is small. Ultimately, the weight of the filler will be transferred to the connection between the support plate 8 and the tower wall 9 or other supporting structures of the packing tower, and the tower wall 8 or other supporting structures will bear the load, which is not conducive to the force balance of the tower wall 8.

[0052] This embodiment effectively promotes gas-liquid heat transfer and improves heat transfer efficiency by staggering the upper and lower beam-type support plates by 90 degrees, while also improving the force balance of the packed tower.

[0053] It should be noted that the staggered angles of the upper and lower beam-type support plates 8 may also be other angles. When there are multiple layers of beam-type support plates 8, a uniform staggered manner may be adopted to make the arrangement and force more balanced.

[0054] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model are included in the protection scope of the utility model.
