Reinforced corrugated bulk filler

Technical Field

The utility model belongs to the technical field of the design and manufacture of mass transfer separation equipment of oil refining, petrochemical, fine chemical industry, medicine, food and environmental protection etc., and relates to a filler, especially a reinforced ripple bulk filler.

Background

The bulk filler is a filler with the basic shape of granules with a certain geometric shape, and is generally filled in a tower in a random stacking mode, and the geometric shape of the bulk filler can be mainly divided into three types, namely a ring shape, a saddle shape and a ring-saddle shape. The surface of the bulk packing used in the separation field is smooth, and based on the understanding of a microscopic mechanism of the interaction of gas-liquid two-phase flow on the surface of the packing, the surface of the packing cannot be completely wetted by a liquid film, but forms complex flow forms such as channeling, stream flow and the like, so that the liquid in the tower is unevenly distributed, a liquid channel in the whole tower is in an unchanged state for a long time, and the liquid film cannot be updated in time, thereby being not beneficial to the mass transfer of gas and liquid and influencing the separation efficiency of the bulk packing.

The general bulk packing, taking the annular packing pall ring as an example, has a packing unfolding schematic diagram as shown in fig. 2, and has a smooth surface. The pall ring packing structure is shown in figure 1, the surface roughness of the packing is not high, the packing is not easy to wet, and the liquid film updating rate is slow.

In order to solve the problems and improve the mass transfer efficiency of the bulk filler, a reinforced corrugated bulk filler is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a reinforce ripple loose packing, through the surface wettability who increases loose packing, reinforcing liquid equipartition improves liquid film update rate, reinforces the mass transfer to improve mass transfer efficiency.

The utility model provides a technical scheme that technical problem adopted is:

the reinforced corrugated bulk packing is made up by using corrugated plate as packing body and making it into ring form, saddle form or ring-saddle form or combination of three kinds of packing.

Moreover, the corrugation depth of the corrugated plate is 50-150% of the thickness of the body, and the peak distance is 1-6 times of the thickness of the body.

Furthermore, the corrugated plate has a corrugation depth of 0.1-2.4 mm.

And, the buckled plate is evenly distributed with the thorn hole, increases the horizontal mixture of liquid.

A reinforced corrugated bulk packing is made up of a main body with regular or irregular concave or convex structure on one or both surfaces. The concave or convex structure is in a point shape or a line shape or a combination thereof.

The concave-convex structure can be concave-convex corrugation, concave-convex dimple, irregular small corrugation, and preferably concave-convex corrugation.

And the filler is made of metal or nonmetal.

The utility model has the advantages that:

1. the utility model takes the corrugated plate as the bulk packing body and is made into a ring shape, a saddle shape or a ring saddle shape. The wetting property of the bulk packing can be improved, so that the contact between packing annular gaps is mainly changed from line contact into point contact when the packing is stacked, the gaps among packing particles are increased, the resistance of gas passing through the packing layer is reduced, the contact points can also be convergence and dispersion points for liquid flowing along the surface of the packing, a good liquid film is easier to form on the surface of the packing, the updating rate of the liquid film is improved, the unfavorable flows such as channeling, stream and the like are eliminated, the transverse mixing of the liquid is enhanced, the mass transfer dead angle is reduced, and the mass transfer efficiency of the packing is improved.

2. The utility model discloses the concave-convex structure of bulk packing has increased the mechanical strength and the rigidity of filler, so can adopt thinner material to prepare, not only reduce the bulk density of packing layer, reduced the manufacturing cost of filler moreover.

3. The concave-convex corrugation of the bulk filler increases the specific surface area of the bulk filler, can reach 50-100 percent, and obviously improves the mass transfer efficiency of the filler.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

The utility model provides a strengthen bulk packing, for example strengthen pall ring, pall ring is one kind of annular packing among the bulk packing.

Example 1
