Description

Regular tower filler

The utility model relates to chemical industry equipment, and concrete is the structured packing (Sicpac) of a kind of packed tower.

Packed tower is fields such as PETROLEUM PROCESSING, chemical industry, medicine and environmental protection a kind of separation equipments commonly used, is widely used in unit processes such as rectifying, absorption, desorb, gas scrubbing, liquid extraction.Tower packing is one of important component part in the packed tower, the performance of tower packing has a significant impact the operating characteristics and the range of application of packed tower, the development of tower packing is very fast in recent years, develop the tower packing of many new structures, new material, and in industrial production, obtained good effect.

The sorting technique of tower packing has many kinds, and distinguishing by its structure and shape has structured packing and granular filler (also crying random packing), and this filler belongs to structured packing.

Using wider structured packing at present has, the metallurgic orifice corrugated packing (Mellapak) of Suhl longevity (Sulger) company exploitation, the rolling metal perforated plate corrugated filler (Gempak) of lattice Ritchie (Glitsch) company exploitation, and ceramic corrugated plate packing (Kerapak) and corrugated wire gauze packing (Goodlon), also has metallic grid filler (Glitsch-Grade) in addition, pulse filler (Impulse-Packing) etc., especially most widely used with Mellapak and Gempak in above-mentioned these fillers, these two kinds of ripple packing geometries are similar substantially, all be to make by thick about 0.2mm metal sheet, the main distinction only is that the microgroove on the Mellapak plate is not cut continuously, the liquid of plate both sides can not interpenetrate, and the lip-deep microgroove of Gempak plate is to be interrupted the seam of cutting, seam is about 5mm, seam interbody spacer 3mm, lip-deep countless finedraws interpenetrate the liquid of plate both sides.The major advantage of this filler is that it has regular geometry in tower, and therefore higher specific surface area, good vapour-liquid have better vapour-liquid mass heat transfer property from distribution performance.Exactly because yet also its regular geometry of shortcoming, 1.. the anti-obstruction, anti-coking performance is relatively poor, be unsuitable for dirtier and easy coking system, 2.. higher to the uniformity requirement that liquid initial distributes, when liquid load was low, the wettability power of filling surface was lower, and influences the heat and mass transfer performance of filler.

The purpose of this utility model is to overcome above-mentioned deficiency, a kind of novel packed tower structured packing is provided, combine the advantage of random packing and structured packing, have strong anti-blockage capability and anti-coking performance, and moistened surface rate preferably all can be arranged, thereby improved the effective ratio area of filler under wider load.

The purpose of this utility model is achieved in that

A kind of regular tower filler, its each unit constitutes the shaped as frame structure of hollow by the metal plate material of disjunctor along the inside and outside bending of joint-cutting and the flanging that intersects, and it is characterized in that:

Its each unit has joint-cutting longitudinally from top to bottom to be divided into 7 taeniaes that two ends connect horizontal edge, wherein the 1st, 4,7 taeniaes are isometric, outwards be bent into curve arc, the 2nd, 6 taeniaes are isometric, inwardly be bent into curve arc, the 3rd, 5 taeniaes each therefrom transversely cutting become not isometric two wing plates and the 3rd, the transversely cutting line left side of the 5th taeniae, dextroposition and the left side section that makes the 3rd taeniae and the 5th taeniae right section is isometric, the right section of the 3rd taeniae is isometric with the left side section of the 5th taeniae, the short left side of this two taeniae, each inwardly is bent into right section wing plate a fixed inclination and is positioned at the 2nd, in the projected outline of 6 arcs that taeniae surrounds, the long left side of this two taeniae, the outside bending intersection of right section wing plate is positioned at the 1st, 4, in the projected outline of the arc that the bending of 7 taeniaes institute forms, and constituting the filler unit of similar rectangular saddle ring shape, each adjacent cells is whole with the affixed one-tenth of edge horizontal stripe.
