Abstract

The utility model discloses a metal regular filler which is at least composed of two layers of mesh-shaped fillers (1), each layer of mesh-shaped fillers are composed of metal strips (2) which are arranged at intervals, at least one row of window holes (4) are arranged on the lateral faces of the metal strips at intervals, window tongue blades (3) are arranged on the window holes, and the metal strips are mutually connected and combined to form the mesh-shaped filler. Since the metal regular filler adopts a through hole honeycomb shape or change the flowing direction of liquid to enable the direction to be vertical, the selectivity is avoided, the liquid can be distributed more evenly, and simultaneously the flowing of gas and liquid can be more smooth. Since big opening windows are arranged on the plate wall of the honeycomb filler, the honeycomb fillers can be freely communicated at small intervals, thereby the horizontal distribution of the gas can be more ideal, the conditions of standard pole plate corrugated fillers that the distribution is not even under the low load condition can be avoided, and the metal regular filler is like a small distributer, reduces the liquid aliquation phenomena, increases the liquid flowing ability, and enables the diffusion of liquid flowing direction to be in the turbulent flow state, thereby greatly improving the liquid separation effect and the separation processing ability.

Description

Metal structured packing

Technical field

The utility model relates in the industrial tower equipment uses filler, especially relates to the metal structured packing that industrial towers such as being used for fine chemistry industry, oil refining, chemical fertilizer, natural gas, oilization uses.

Background technology

Current, the drying tower, scrubbing tower and the knockout tower filler that are used for industry such as fine chemistry industry, oil refining, chemical fertilizer, natural gas, petrochemical industry, because the requirement of industrial separation tower technology technology, the industrial separation tower mostly uses the corrugated regular filler that is formed by some corrugated potteries or the interlaced stack of metallic plate monomer.But corrugated regular filler is when piling up mutually up and down, linearly shape and vertical interlaced, its packing ratio surface area is not too high, and flux is lower, liquid flowing resistance is bigger, Liquid Flow speed is slow, when liquid when these ducts flow downward, because ripple packing is layering, therefore oblique downward liquid optionally flows to certain duct under effect of inertia, this selectivity can be more and more stronger, makes distribution of liquid extremely inhomogeneous at last, causes the separating treatment ability low.

The utility model content

The purpose of this utility model is to provide a kind of separative efficiency height, metal structured packing that the separating treatment ability is big.

The technical scheme that the technical problems to be solved in the utility model is taked is: described metal structured packing is made up of two layers of mesh pass filler at least, every layer of mesh type filler is spaced by metal strap and forms, the layer with layer between the metal strap fissure of displacement corresponding, be arranged at intervals with at least one row's fenestra on the described metal strap side, fenestra is provided with the window ligule, and metal strap interconnects and is combined to form the mesh type filler.

Described window ligule preferably is circular arc, also linearly type or bending shape, Integratively formed when described window ligule was preferably processed fenestra on metal strap, certainly also can behind the processing fenestra, on the fenestra limit, weld or riveted joint window ligule, window ligule between the described metal strap can be provided with in the same way, also can oppositely be provided with, described fenestra preferably is square or rectangle.

Also can be provided with the microgroove of strip, point-like or other shape on the described metal strap surface, and be pressed into ripple, to promote the renewal on liquid film surface by certain angle.

Described metal structured packing is the cylinder bodily form, the semicolumn bodily form, the square bodily form, cuboid or the prismatic bodily form and other shape.

The utility model is owing to adopt the clear opening honeycomb type, or makes it vertical to change flow direction, thereby avoided its selectivity, makes liquid distribution more even, also makes flowing of gas-liquid more smooth simultaneously.In addition, because having greatly, the wooden partition of honeycomb filler windows, the closely-spaced of them freely is communicated with, thereby the horizontal distribution of gas is better, can situation pockety not occur, its similar small distributor like that under low loading condition by the accurate perforated plate corrugated filler of image scale, reduced the liquid segregation phenomena, increased the liquid communication ability, made flow direction disperse to be turbulent condition, thereby improved fluid separation applications effect and separating treatment ability greatly.

The specific embodiment

At Fig. 1, among Fig. 2 and Fig. 3, described metal structured packing is cuboid, it is made up of three-layer network pass filler 1, described mesh type filler 1 is combined to form by the metal strap 2 of equal length, the layer with layer between the metal strap fissure of displacement corresponding, described metal strap is made with sheet metal, on the metal strap side of every layer of mesh type filler, be processed with two row's fenestras 4, the two rows fenestra is parallel and be crisscross arranged, described fenestra is a rectangle, being processed clout three limits of getting off by cutting in the fenestra separates with fenestra, and another side still is connected on the fenestra, again this clout bending machining being formed section is the window ligule 3 of circular shape, window ligule bending direction on every metal strap is identical, successively with the window ligule on the metal strap that processes near on another piece metal strap, with the window ligule metal strap is interconnected, make it form the all-in-one-piece mesh type filler of one deck, both sides all are fixedly linked with connecting rod 5 between every layer of mesh type filler, window ligule between the metal strap can be provided with in the same way, also can oppositely be provided with.Described metal structured packing also can the side's of being bodily form, the cylinder bodily form or the prismatic bodily form and other shape.

Claims

1. metal structured packing, it is characterized in that: it is made up of two layers of mesh pass filler (1) at least, every layer of mesh type filler is spaced by metal strap (2) and forms, the layer with layer between the metal strap fissure of displacement corresponding, be arranged at intervals with at least one row's fenestra (4) on the described metal strap side, fenestra is provided with window ligule (3), and metal strap interconnects and is combined to form the mesh type filler.
