Each packing unit comprises an upper top face, a lower face and a side face, metal plate corrugated plate corrugated packing and thickening metal plate corrugated plate corrugated packing are vertically placed inside each packing unit in a stagger mode, side faces of the plurality of packing units are attached and connected in a spliced mode to combine the packing trays, the directions of the plate corrugated packing internally arranged between every two adjacent packing units are intersected, an upper packing tray and a lower packing tray which are adjacent rotate 30 degrees-90 degrees, a whole packing tray is divided into a plurality of pieces of gas-liquid two-phase channels which are parallel to one another and independent, additional pressure drop generated in the process that fluid passes through a Z-shaped channel is avoided, gas phase resistance is low, flux is large, higher mass transfer efficiency is achieved, utilization of metal plate corrugated packing with flow guiding openings enables the internal metal plate corrugated plate corrugated packing to be free of being extruded by external force and the metal plate corrugated plate packing is free of being bent and deformed, strength and corrosion-resistance capability of the packing trays are improved, corrosion of the packing is slowed down, and the service cycle of the packing is prolonged.
Description
[technical field]
The utility model relates to the oil-refining chemical industry, relates in particular to a kind of generally for the filler of oil refining industry.
[background technology]
Tower packing is the core internals of packed tower, and its effect is for gas, liquid two-phase provide abundant and close contact, to realize mass transfer between the phase border (or conduct heat) process, by structure and the occupation mode of packing component, can be divided into loose heap and regular two large classes.Random packing is the granule that has one by one certain geometrical shape and size, generally in random mode, be deposited in tower, structured packing is to arrange according to certain geometrical configuration, the filler of neatly piling up, due to its even structure, rule, symmetry, when with random packing, thering is identical specific area, the voidage of filler is larger, there is larger flux, comprehensive treatment capability is more much bigger than plate column and random packing tower, and structured packing generally can be divided into grid packing, ripple packing, Impulse packing.The utility model relates to the ripple packing in structured packing, and ripple packing is the maximum regular condiment of current industrial application.But use many problems that exist in the ripple packing environment higher in corrosivity, in the vacuum tower in oil refining apparatus, under the effect of corrosive medium, filler is corroded and deforms, that the resistance of tower is increased, porosity reduces, cause the decrease in efficiency of tower, the filler life-span is die-offed, the product quality fluctuation is large, what impact was produced normally carries out, the researcher attempts to solve efficient under corrosive environment always, high flux, the mass transfer problem that low-resistance is fallen, improved procedure one class is the utilization of New Type Material, as titanium alloy, pottery structured packing as efficient as CN1193957C and plastics etc. is come out one after another, but titanium alloy is expensive, pottery is nonelastic, frangible, and can't be adjacent to wall, and the wall flow increases, the filler of plastic material is unsuitable for the higher environment of temperature, to most of organic solvents are not corrosion-resistant and surface wettability is poor, another kind of is that chemical treatment is done as CN1166813C in traditional metallic plate ripple packing surface, this type of filler only is applicable to specific medium, can not extensive use, and because common metal mellapak packing overdraught is non-uniform flow, pressure drop increases, reduce mass transport process, made operating cost improve.
