Abstract

The utility model relates to a figure-eight ring packing, which is characterized in that a figure-eight ring is composed of two identical and mutually symmetrical oblate rings (a, b), and the high diameter ratio of the rings is between 0.2 and 0.5. The rings are provided with holes, and inward bent arched rib (C) structures are arranged in the rings.

Description

8-shaped ring packing

The utility model relates to a kind of 8 type ring fillers, belongs to tower packing.

As everyone knows, that packed tower has is simple in structure, operating flexibility big, the disposal ability advantages of higher, is able to extensive use in fields such as petrochemical industry, medicine and environmental protection.The kind of filler is a lot, the consumption maximum be dumped packing.Distinguish from geometry, ring packing, saddle packing etc. are arranged.

Fillers such as dumped packing in one's early years such as Raschig ring, Pall ring, cascade ring may be upright after filling, also may accumbency.The inclination angle of the axis direction of filler and the horizontal plane of tower is random distribution between 0 °～90 °, the filler of some accumbency or accumbency basically is because the shielding action of its outer surface, the mobile inner surface of filler that makes that has hindered two-phase is difficult to play a role, so not only increased the flow resistance of two-phase, influence disposal ability, also reduced mass-transfer efficiency.In addition, the inhomogeneity influence of the muscle sheet form fluid flow in the filler is also unreasonable.

For improving the mass-transfer efficiency of these ancient fillers, the flat-ring packing that released one after another both at home and abroad makes the interior arrangement of tower of filler comparatively orderly, and the above-mentioned weakness of filler is relaxed, but there is no the change of essence.

The purpose of this utility model is filler-a kind of 8 type ring fillers that a kind of new structure will be provided, and just can present a kind of orderly arrangement when the utility model filler huddles in tower, has eliminated filler accumbency phenomenon basically.

The purpose of this utility model is achieved in that with metal, pottery or plastic or other material, make two identical and symmetrical flat garden rings or ellipse garden ring, overlook and be " 8 " font, shape perforate on ring, and in adopting curved arched ribs chip architecture to improve filling intensity.

The utility model is because make substantial change from the filler overall structure, and institute is so that the arrangement of filler is more orderly, thus the utilization rate of raising packing specific area, and then improved mass-transfer efficiency, reduced the filler pressure drop.

The utility model filler also has the following advantages:

1. form a kind of new packing with two identical and symmetrical flat gardens (ellipse garden) ring.Like this, just can present a kind of orderly arrangement when filler of the present invention huddles in tower, eliminate filler accumbency phenomenon basically, improve the utilization rate of filler specific surface, thereby improved mass-transfer efficiency, also reduce the filler resistance simultaneously, increase disposal ability.

2. curved arc rib has improved the circulation of filler inside to improve filling intensity in adopting, and makes the distribution of two-phase fluid more even, thereby has further improved the filler mass-transfer efficiency.

3. kept existing new packing voidage height, the advantage that disposal ability is big.

4. be easy to processing.Can adopt common used materials such as metal, pottery, plastics.For metal material (plate), can be through simply being stamped to form.

In sum, the utility model is compared with existing dumped packing (cascade ring etc.), and mass-transfer efficiency can improve about 10%.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the front view according to a kind of 8 type ring fillers that the utility model proposes, and wherein a, b are two flat garden rings.Fig. 1 also can be used as Figure of abstract.

Fig. 2 is the vertical view of Figure 18 type ring filler, and wherein C is the muscle sheet.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the 8 type ring fillers that the utility model proposes.

With two identical and symmetrical flat garden rings (a, b) (referring to Fig. 1) of metallic plate punching.Making the ratio of height to diameter of a, b ring is 0.2～0.5, and interior curved arc rib (C) is adopted in perforate on the ring in the ring, overlook to be figure of eight shape (referring to Fig. 2), and this structure is improved the circulation of filler inside to improve filling intensity.And can present a kind of orderly arrangement when in tower, huddling, eliminated filler accumbency phenomenon basically.

The utility model can also adopt pottery, and plastic material is made, and this is easy to realize for a person skilled in the art.

Claims

1, a kind of 8 type ring fillers is characterized in that said 8 type rings encircle (a, b) by two identical and symmetrical flat gardens and form.

2, packing ring according to claim 1 is characterized in that the ratio of height to diameter that encircles is 0.2～0.5, and perforate on the ring is interior curved arc rib (C) structure in the ring.

3, packing ring according to claim 1 is characterized in that said two identical and symmetrical flat garden rings can be ellipse garden rings.
