Description

Technical Field

[0001] The utility model relates to the technical field of packing supports, in particular to a keel-type structured packing support. Background Technique

[0002] Tower equipment is one of the most important equipment in the production of chemicals, oil refining, pharmaceuticals, and food. It enables close contact between gas-liquid or liquid-liquid two phases to achieve the purpose of interphase mass transfer and heat transfer. When focusing on the optimized design of a series of hardware such as new and efficient tower trays, new and efficient packings for packed towers, new gas-liquid distributors, new inlet gas distributors, and secondary gas distribution trays, the optimized design of the support device for large tower vessels must not be ignored. The keel-type structured packing support is a structure used in packed towers, which provides support and fixation for structured packings.

[0003] For example, Chinese Patent CN221085644U discloses a keel-type structured packing support, which is assembled by inserting and connecting a main keel, a secondary keel, a drip plate, a support ring, and a beam. By stamping out a roof-shaped keel frame, the strength and stiffness of the plate are greatly improved, and thus thinner plates can be selected. For structured packing towers with large tower diameters and high packing layers, the height and quantity of the main beams can be effectively reduced, thereby saving materials and reducing the height of the tower body to a certain extent. The side of the main keel is provided with a limit socket, and the end of the secondary keel is provided with a socket. A special tooling clamp can be used to quickly and accurately complete the installation inside the tower, and the overall flatness and stability are good. The main keel with a gas closing port and the drip plate with a cut-off port achieve good gas-liquid passability.

[0004] The above patent uses a support beam fixed under the main keel by fixing parts welded to the tower wall on both sides as a support. However, the shape of the support beam in this patent is a rectangular strip, and the stability of the support is general, reducing the practicability. Content of the Utility Model

The limiting grooves are formed on the lower surfaces of the moving columns. No less than two of the limiting blocks are arranged in a circular shape on the lower surface of the support ring. No less than two of the inserting slots are formed in a circular shape on the upper surface of the annular support frame. The limiting blocks are slidably inserted into the inner parts of the inserting slots.

[0014] By adopting this technical solution, rotating the rotating handle can drive the threaded rod to move up and down inside the connecting piece.
