Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of anti-wall flow devices, specifically relating to a detachable anti-wall flow device. Background Technology
[0002] Packed towers, as a modern separation, mass transfer, and heat transfer device, are widely used. However, phenomena such as wall flow, deviation flow, and channeling flow in the liquid phase of packed towers can all lead to a decrease in separation efficiency, with wall flow being a particularly critical factor. Therefore, to prevent gas-liquid wall flow during installation due to gaps between the packing and the tower wall, anti-wall flow rings need to be installed in these gaps.
[0003] Existing anti-wall flow rings are usually made as a single piece, and the material is metal or resin (PTFE). In high temperature and highly corrosive acidic environments, their corrosion resistance is insufficient, which can easily lead to a decrease in structural strength and make it difficult to meet the requirements of long-term stable operation. At the same time, the integral structure is difficult to adapt to different tower diameters and installation environments, which brings great inconvenience to manufacturing and installation. Utility Model Content

[0007] In some embodiments, the sheet is located between the packing and the tower wall, the outer wall of the sheet abuts against the tower wall, and the lower part of the inner wall of the sheet abuts against the outer periphery of the packing.
[0008] In some embodiments, the sheet includes a support sheet that extends upwardly at an angle to form a guide sheet for guiding liquid falling onto its surface into the filler.
[0009] In some embodiments, the included angle α between the support plate and the guide plate is 20 to 40°.
[0010] In some embodiments, a gap is provided between two adjacent guide vanes.

[0024] While existing anti-wall flow devices can prevent liquid from flowing to the tower wall to some extent, the existing anti-wall flow rings are usually made as a single unit. In highly corrosive acidic environments, their corrosion resistance is insufficient, which can easily lead to a decrease in structural strength and make it difficult to meet the requirements for long-term stable operation. At the same time, the integral structure is difficult to adapt to different tower diameters and installation environments, which brings great inconvenience to manufacturing and installation.
[0025] This application is described below with reference to the accompanying drawings and specific embodiments:
[0026] This invention provides a detachable anti-wall flow device that can operate stably for a long time in high-temperature and highly corrosive acidic environments. It solves the problem of easy damage and failure of anti-wall flow rings in high-temperature and highly acidic environments in the prior art, and improves service life and reliability. The splicing design allows it to be installed in several sections according to actual needs, which greatly improves the flexibility and adaptability of installation. It effectively solves the problems of space limitations and inconvenient transportation encountered in the installation of integral anti-wall flow rings, reduces installation costs and time, and facilitates subsequent maintenance and replacement.
[0027] Specifically:
[0028] Please see Figure 1-3 A detachable anti-wall flow device includes an annular structure formed by splicing at least two sheets 10. The sheets 10 are made of carbon fiber. The annular structure formed by splicing at least two sheets 10 provides the anti-wall flow device with extremely high flexibility during installation, especially in large towers or environments with limited space. Split installation can reduce installation difficulty and improve installation efficiency. Furthermore, the flexible design allows the anti-wall flow device to fit tightly against the tower wall.
[0029] In some embodiments, such as Figure 2and Figure 3 As shown, the sheet 10 has a fixing ear and a fixing groove on both sides, and the fixing ear and the fixing groove are corresponding to each other. The sheet 10 can be connected together by fixing bolts.
[0030] In other embodiments, the sheets 10 may be joined together to form a ring structure, and the sheets 10 may be fixed to the tower wall by a support structure.
[0031] In some embodiments, the surface of the sheet 10 is provided with an anti-slip structure for self-support between the packing and the tower wall. The anti-slip structure can increase the friction between the sheet 10 and the tower wall, ensuring that the anti-wall flow device can be stably supported on the tower wall during operation. At the same time, the anti-slip structure can also increase the friction between the sheet 10 and the packing.
[0032] In some embodiments, the anti-slip structure is a diamond-shaped protrusion, which is molded and has a height of 0.5–1.0 mm. The diamond-shaped protrusion increases the contact area and friction between the sheet 10 and the tower wall and packing. It also disperses the contact stress between the sheet and the tower wall and packing, preventing wear and damage caused by stress concentration.
[0033] In some embodiments, the sheet 10 is located between the packing and the tower wall, with the outer wall of the sheet 10 abutting against the tower wall and the lower part of the inner wall of the sheet 10 abutting against the outer periphery of the packing, so that the anti-wall flow device can fit tightly between the packing and the tower wall, effectively preventing liquid from flowing from the gap between the packing and the tower wall to the tower wall, thereby avoiding product quality problems caused by liquid flowing to the tower wall.
[0034] In some embodiments, the sheet 10 includes a support sheet 11 that extends upward at an angle to form a guide plate 12 for guiding liquid falling onto its surface into the packing. The guide plate 12 can effectively guide liquid falling onto its surface into the packing, avoiding the accumulation and retention of liquid on the anti-wall flow device, and improving the uniformity of liquid distribution and the utilization rate of the packing.
[0035] In some embodiments, the included angle α between the support plate 11 and the guide plate 12 is 20 to 40°, so that the liquid can be smoothly guided into the packing.
[0036] In some embodiments, a gap is provided between two adjacent guide vanes 12 to prevent liquid from accumulating on the anti-wall flow device and to guide the liquid, while also better adapting to the bending of the carbon sheet 10.
[0037] According to the actual needs of the packed tower, select the number of sheets 10, and connect multiple sheets 10 together to form a ring structure. Then, put the anti-wall flow device and the packing into the tower together. The bottom packing is supported by the support grid, so that the outer wall of the sheet 10 on the anti-wall flow device abuts against the tower wall, and the lower part of the inner wall of the sheet 10 abuts against the outer periphery of the packing.
[0038] In use, when liquid flows down from the top of the tower or the tower wall and comes into contact with the anti-wall flow device, the liquid touches the guide plate 12. Under the guidance of the guide plate 12, the liquid falling on its surface is guided into the packing.
[0039] The carbon fiber material design effectively resists erosion from high temperatures and highly corrosive acidic environments, extending the service life of the anti-wall flow device. The anti-slip structure design allows the anti-wall flow device to be supported solely by the friction between the packing and the tower wall.
