Description
Technical field
The utility model belongs to technical field of chemical, particularly relates to a kind of percolation tower tray.
Background technology
Percolation tower tray is a kind of tower tray without overflow mechanism, and the percolation tower tray used at present mainly contains sieve mesh type and angle steel formula two kinds, because its structure is simple, treating capacity large, is widely used in the industrial process such as the absorption of large-scale oil refining and gas, dedusting.
CN102309867A discloses a kind of Large flow through sieve plate tower and column plate, the novel percolation sieve tray alternately arrangement of two kinds of different structures is had in this tower, the novel percolation sieve tray of often kind of structure is by installing traditional percolation sieve tray piecemeal and adding flow apron to realize in each column plate sub-block, this structure can ensure the levelness that in it, every grade of percolation sieve tray is installed, and effectively reduces plate pressure drop; CN2358962Y discloses a kind of limit mouth above-below direction spaced angle-piece percolation tower tray, the upwards angle-piece group that this tower tray is made up of angle-piece and downward angle-piece group, then with two frames upwards, downwards angle-piece group form plate-like or blocks.When keeping gas phase channel to have identical free cross-sectional area, the angle steel that the angle-piece of this structural arrangement arranges than unidirectional angle steel percolation tower tray is many, and heat transfer area is larger.But the percolation tower tray gas liquid interfacial area of above-mentioned two kinds of structures is less, and easily form local eddy currents, droop loss is larger.
Utility model content
The purpose of this utility model is to provide the percolation tower tray that a kind of gas liquid interfacial area is large, droop loss is little.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of percolation tower tray, comprise gripper shoe and be arranged at the pipe assembly in gripper shoe, described pipe assembly cross section is water-drop-shaped, and pipe assembly is spaced on the supporting plate.
Described pipe assembly is made up of two surface plates and a curved slab, and curved slab and surface plate are interconnected, and its cross section is water-drop-shaped, and the angle between two surface plates is 10 ° ~ 120 °.
The described width of water-drop-shaped pipe assembly is 1 ~ 10 with the ratio of inter-module gap width.
Heating or cooling medium is passed in described water-drop-shaped pipe assembly.
Compared with prior art, the utility model has the advantages that:
1, the utility model percolation tower tray is spaced by water-drop-shaped assembly and forms, and is applicable to the liquid containing a large amount of SS or fibrous solid content, not easily blocks;
2, water-drop-shaped assembly is made up of top dihedral section (two surface plates form dihedral section) and lower curved face section, defines closed structure, and compared with angle-piece, the steam of bottom rises through fairshaped curved surface, and can not form eddy current, droop loss is little;
3, water-drop-shaped assembly is compared with angle-piece with sieve aperture, adds the surface area of gas-liquid contact, significantly can improve the heat and mass efficiency of tower tray.

Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of percolation tower tray, comprises water-drop-shaped pipe assembly 1 that the dihedral section 11 that is made up of two surface plates and curved sections 12 form and gripper shoe 2 forms.In process of production, percolation tower tray by water-drop-shaped inter-module every rearranging; The assembly of adjacent two tower trays is staggered distribution, and its spacing can be equal, also can not wait; On tower tray, water-drop-shaped assembly can formal dress (as shown in Figure 1), anti-dress (as shown in Figure 3) or load in mixture (as shown in Figure 4), according to tower diameter size, can form plate-like or bulk.
Water-drop-shaped pipe assembly 1 comprises dihedral section 11 and curved sections 12, the structure that the two composition is closed, and material can be carbon steel, stainless steel, also can be the nonmetallic materials such as engineering plastics, graphite.The horizontal width of water droplet shaped piece is 1 ~ 10 with the ratio of inter-module gap width, and component count is determined according to process conditions; Dihedral section 11(is that is between two surface plates) angle be 10 ~ 120 °, it can process fin, projection, pit or decorative pattern; Curved sections 2 can be the convex surfaces such as circle, ellipse, oblateness or parabolic type.
During utility model works, the assembly of adjacent trays can be orthogonal, also can tower tray is orthogonal between two.Material drops on water-drop-shaped pipe assembly and flows downward, and water-drop-shaped pipe inter-module is also gas rising passway simultaneously; Because adjacent two tower tray assemblies are staggered distribution, between tower tray, point cloth is orthogonal, and material is more evenly distributed.Water-drop-shaped pipe assembly is made up of dihedral section 11 and curved sections 12, and gas liquid interfacial area is increased greatly, and heat and mass efficiency significantly improves; When walking around streamlined structure when gas rises, resistance is little, owing to adopting this special flow line structure of water-drop-shaped, tower tray pressure drop is significantly reduced.
In the utility model, the two ends of water-drop-shaped assembly can be closed, and also can open wide, and according to technological requirement, can pass into heating or cooling medium in pipe.
