Description

Technical Field

[0001] The utility model relates to the technical field of packing support, and more specifically to a polytetrafluoroethylene packing grid with a detachable and flow-guiding structure. Background Art

[0002] The reaction tower is generally a high-temperature, high-pressure, and highly corrosive environment. Therefore, the accessories in the tower have a certain service life and need to be replaced once damaged. However, the grids used for the fillings in some towers are fixed whole-piece grid structures. The grids of some larger tower sections are difficult to make and require high production processes. In addition, the weight of the whole piece is large after production. Installation and disassembly require the tower sections to be disassembled and separated, which will cause considerable delays in the actual production. Before disassembling the tower sections, the tower sections must be cleaned to avoid material loss (economic loss); disassembling the tower sections will affect equipment safety (easy to damage the equipment), environmental safety (material leakage pollutes the environment), and personnel safety (on-site personnel operation safety).

[0003] The existing patent is a detachable polytetrafluoroethylene grille, and the larger grille in the patent authorization number CN220361200U is divided into multiple grille units, and the grille units are detachably connected through a frame and a mounting plate, which reduces the difficulty of manufacturing. At the same time, the weight of a single component is much lighter than that of the whole piece, and the lifting is relatively easy; in addition, this structure allows the grille to be disassembled. When replacing, there is no need to dismantle the entire tower section, and it can be replaced through the manhole, reducing manpower and economic losses and avoiding impacts on environmental safety.

[0004] However, the connection between the frames in patent authorization number CN220361200U needs to be connected by bolts, and the frame and the connecting plate are connected by bolts. The connection is very inconvenient, the installation efficiency between the connecting plates is low, and it does not have the function of guiding the spray liquid, which easily causes the spray liquid to gather in the packing part, resulting in a large loss of the spray liquid. Therefore, we proposed a PTFE packing grid with a detachable and diversion structure to solve the above problems. Utility Model Content
