Description

Technical Field

[0001] The invention relates to the technical field of packing in a packing tower, in particular to a rosette packing with improved compressive strength. Background Art

[0002] Packed towers are among the most important pieces of equipment in petroleum and chemical production. Liquid is sprayed from the top of the tower through a liquid distributor onto the packing, flowing down along the packing surface. Gas enters from the bottom of the tower, is distributed by the gas distributor, and then continuously flows through the gaps in the packing layer in a countercurrent flow with the liquid. On the packing surface, the gas and liquid come into close contact, allowing mass transfer. Therefore, the packing structure and properties, packing layer height, and porosity are crucial factors influencing the mass transfer efficiency of packed towers.

[0003] Rosette fillers are widely used due to their simple processing and manufacturing, good corrosion resistance, light weight, large porosity, small resistance, not easy to clog, low energy consumption and reusability. The existing rosette packing is mainly an annular curved surface structure with many contact points. The patent with publication number CN202121540439.5 discloses a new rosette packing for use in packing towers. It includes an inner ring, and several groups of ring components are fixed on the outer circumference of the inner ring. All ring components are aligned with the center of the inner ring. Each ring component is evenly distributed circumferentially along the outer circumference of the inner ring, and the middle part of one side between two adjacent ring components is connected by a first reinforcement body; the ring component includes two circular rings at an angle to each other, and the middle part of one side between the two adjacent circular rings is connected by a second reinforcement body, and the first reinforcement body and the second reinforcement body are staggered up and down; it also includes an outer ring, which is movably mounted on the outside of several groups of ring components, and a positioning ball is fixed on the outer circumference of each circular ring. An inwardly recessed arc-shaped groove is opened on the inner wall of the outer ring along its circumference, and the positioning ball on the circular ring is connected to the arc-shaped groove on the outer ring by a snap fit. This type of garland packing is prone to nesting and overlapping when stacked in bulk in a packing tower, resulting in a decrease in the porosity and effective flux area of ​​the garland packing, and a reduction in mass transfer efficiency; at the same time, the structural design of the garland packing is not reasonable, and the petal ring and outer ring skeleton lack effective internal support. During the stacking and use in the packing tower, many garland packings will be squeezed, deformed, and broken, causing the pressure difference in the tower to increase, and pipelines and equipment to be blocked, affecting the use effect; in addition, the inner ring and outer ring of this garland packing are separate, and need to be manually assembled and installed together when used, which increases the operating procedures, low production efficiency, and the product strength cannot be maintained consistent. Summary of the Invention

[0004] In order to overcome the shortcomings of the current rosette packing technology, the utility model provides a rosette packing with improved compressive strength, which solves the problems of the existing rosette packing that is easy to nest and overlap, has low mass transfer efficiency, poor compressive strength and short service life.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A garland filler with improved compressive strength includes an outer ring body, an inner ring body, a petal ring, and petal inner ribs. The outer ring body is concentrically arranged with the inner ring body, the petal ring connects the outer ring body and the inner ring body together, and the plane where the petal ring is located is perpendicular to the plane of the outer ring. The garland filler also includes an outer circular ring, which is composed of two circular rings that intersect vertically. The two outer circular rings are distributed and intersect vertically with the outer ring body, and the whole is spherical.

[0007] Furthermore, each petal ring is provided with a support column, the support column is perpendicular to the outer ring, and each outer ring is connected with a reinforcing rib.

[0008] Furthermore, the rosette filler is made of plastic, including but not limited to PVC, RPVC, CPVC, PVDF, etc.

[0009] The beneficial effects of the utility model are as follows: compared with the existing technology, the structure is optimized and designed to be spherical, which eliminates the mutual nesting and overlapping of the garland packings, increases the porosity and contact area of ​​the garland packings, and thus improves the mass transfer efficiency; after the petal ring and the outer ring are connected by supporting columns and reinforcing ribs, the compressive strength of the garland packing is improved, and it is not easy to deform or break when used in a packing tower, effectively preventing blockage and extending the service life.

[0013] Now, the embodiment of the present invention will be described in further detail with reference to the accompanying drawings:

[0014] Example 1, reference Figure 1 and Figure 2A garland filler with improved compressive strength includes an outer ring body 1, an inner ring body 2, a petal ring 3, and petal inner ribs 4. The outer ring body 1 is concentrically arranged with the inner ring body 2, and the petal ring 3 connects the outer ring body 1 and the inner ring body 2 together. The petal ring 3 is provided with petal inner ribs 4, and the plane where the petal ring 3 is located is perpendicular to the plane of the outer ring body 1. The garland filler also includes an outer circular ring 5, which is composed of two circular rings that intersect vertically. The two outer circular rings 5 ​​are distributed perpendicularly to the outer ring body 1 and are spherical as a whole. The petal ring 3 is connected by a support column 6, and the two outer circular rings 5 ​​are provided with reinforcing ribs 7.

[0015] Compared with the existing garland packing technology, the garland packing of the utility model has been structurally optimized and designed to be spherical, which eliminates the mutual nesting and overlapping of the garland packings, increases the porosity and contact area of ​​the garland packing, and thus improves the mass transfer efficiency of the gas-liquid two-phase in the packing tower; after the petal ring and the outer ring are connected by supporting columns and reinforcing ribs, the compressive strength of the garland packing is improved, and it is not easy to be squeezed, deformed or broken during the use of the packing tower, which can prevent blockage and effectively extend the service life of the garland packing.
