Description

Technical Field

[0001] The utility model relates to the technical field of random dumped metal packing, in particular to a novel 84 inner arc ring packing. Background Art

[0002] Packings are widely used in tower equipment such as cooling towers, scrubbing towers, absorption towers, and regeneration towers in industries such as oil refining, metallurgy, and chemical engineering. They can be classified into plastic, metal, and ceramic packings according to materials, and into dumped and structured packings according to the installation form. The function of the packing is to provide a contact surface for the gas-liquid two-phase and create conditions to improve its turbulence degree (mainly for the gas phase) to facilitate mass transfer (including heat transfer).

[0003] The 84 inner arc ring is a common structure in random dumped packings. However, in the prior art, in order to ensure the smooth flow effect of the fluid, the 84 inner arc ring usually adopts a structure with consistent upper and lower through connections, and there are relatively large gaps between the rib sheets inside the arc ring, resulting in insufficient segmentation and blocking of the fluid when passing through the inside of the arc ring, and it is difficult to achieve sufficient turbulent flow contact.

[0004] Therefore, we propose a novel 84 inner arc ring packing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a novel 84 inner arc ring packing to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A novel 84 inner arc ring packing includes a first ring body and a second ring body. The first ring body and the second ring body are connected by a plurality of symmetric rib sheets. A positive cross is fixed inside the first ring body, and the positive cross divides the first ring body into four first through areas equally. An inclined cross is fixed inside the second ring body, and the inclined cross divides the second ring body into four second through areas equally. The inclined cross and the positive cross overlap to form a "rice" shaped structure. The first through areas and the second through areas are staggered with each other. Inner arc sheets are connected end to end between adjacent rib sheets, and the arc surface where the inner arc sheets are located divides the first through areas and the second through areas equally.

[0008] In a further embodiment, the first ring body and the second ring body have the same structure, and the first ring body is formed by connecting a plurality of convex arc parts and concave arc parts end to end.

[0009] In a further embodiment, both the number of the convex arc parts and the concave arc parts is eight.

[0010] In a further embodiment, the inner arc sheets and the concave arc parts are concentric arcs.

[0011] In a further embodiment, the four ends of the upright cross are respectively fixed to the four spaced concave arc portions of the first ring body, and the four ends of the oblique cross are respectively fixed to the four spaced concave arc portions of the second ring body.

[0012] In a further embodiment, the number of ribs is set to four, and the four ribs are respectively connected to the four spaced concave arc portions of the first ring and the second ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up a double-layered ring body and distributing staggered crosses, inner arc plates, and oblique crosses between the double-layered ring body, ensures that the central through hole of the entire 84 inner arc ring is evenly divided into small holes by the crosses, inner arc plates, and oblique crosses, thus guaranteeing sufficient fluid flow gaps in the passage area. At the same time, the staggered distribution of the crosses, inner arc plates, and oblique crosses effectively divides the flowing medium in the packed tower, thereby promoting gas-liquid contact and achieving full exchange.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5A novel octagonal inner arc ring packing includes a ring body 1 and a ring body 2. Ring body 1 and ring body 2 have identical structures. Both ring body 1 and ring body 2 are formed by sequentially connecting eight convex arc portions 11 and eight concave arc portions 12, resulting in an octagonal outer perimeter. Ring body 1 and ring body 2 are connected by four spaced-apart ribs 3, which respectively connect to the four spaced-apart concave arc portions 12 of ring body 1 and ring body 2. A cross 4 is fixed inside ring body 1, with its four ends fixed to the four spaced-apart concave arc portions 12 of ring body 1. The cross 4 divides ring body 1 into equal parts. The ring is divided into four passage zones. Four inner arc plates 5 are connected end to end between the four ribs 3. The inner arc plates 5 are concentric arcs of the concave arc portion 12, and their centers coincide. An inclined cross 6 is fixed inside the ring body 2. The inclined cross 6 divides the ring body 2 into four passage zones. The four ends of the inclined cross 6 are fixed to the four spaced concave arc portions 12 of the ring body 2. Since the inclined cross 6 and the upright cross 4 are staggered and overlapped to form a "rice" shaped structure, and at the same time the four inner arc plates 5 are staggered and separated, the space inside the ring body is divided into multiple small cells, thereby effectively dividing the flowing medium in the packed tower and promoting gas-liquid contact.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
