Background technology
Packed tower, as a kind of traditional gas, liquid mass transfer apparatus, grows a lot in recent years, and due to updating of filling-material structure, in a lot of production process, packed tower instead of traditional plate column.The filler that packed tower in current gas, liquid mass transfer apparatus adopts mainly is divided into random packing and the large class of structured packing two.Random packing is the granule one by one with certain geometrical shape and size, is generally deposited in a random way in tower, is also called dumped packing or granular filler.Random packing is different according to design feature, can be divided into again ring packing, saddle packing, ring saddle packing and Ball-type packing etc.Comparatively typical dumped packing comprises Raschig ring, Pall ring, cascade ring etc.But because the bulk density of random packing is comparatively large, the load-carrying of tower load is large, and gas-liquid distribution is poor, and mass-transfer efficiency is low, and resistance is large, and flux is little, easily blocks, and makes the life cycle of equipment shorten.
Structured packing is by certain geometric arrangements, the filler neatly piled up.Structured packing kind is a lot, can be divided into grid packing, ripple packing, Impulse packing etc. according to its geometry.
Grid packing forms through certain principle combinations with bar element body, has various structures form.The specific area of grid packing is lower, is mainly used in requiring that pressure drop is little, load is large and the occasion such as anti-blocking.The structured packing overwhelming majority industrially applied is ripple packing, the discoid filler that it is made up of many corrugated sheets, and there are 30 ° and 45 ° two kinds in the inclination angle of ripple and tower axle, and during assembling, adjacent two corrugated platings are oppositely by folded.Each dish filler is vertically loaded in tower, staggered 90 ° of arrangements between two adjacent dish fillers.The shortcoming of ripple packing be unsuitable for process viscosity greatly, be easily polymerized or have the material of suspension, and handling, cleaning difficulty, cost is high.
Impulse packing is individual by the hollowed out prism of band necking down, by a kind of structured packing that certain way is assembled.Impulse packing assembling after, can be formed band necking down porous prismatic passage, its vertical surface current road alternating contractions and expansion, gas-liquid two-phase by time produce strong turbulence.In necking segment, gas speed is the highest, and turbulence is violent, thus strengthening mass transfer.At expanding reach, gas speed reduces to minimum, realizes the separation of two-phase.The alternately repetition that runner shrinks, expand, achieves " pulse " mass transport process.The feature of Impulse packing is that treating capacity is large, and pressure drop is little, is the ideal filler of rectification under vacuum.Because its excellent liquid-distribution property makes enlarge-effect reduce, therefore be specially adapted to the occasion of large tower diameter.
Patent 201120285362.1 discloses a kind of regular corrugation filler, main on the dual-side that regular corrugation filler sheet is corresponding, be respectively arranged with lateral opening band, lateral opening bring be provided with lateral opening, when the regular corrugation filler sheet with lateral opening band forms plate shape filling with the superposition of inclination angle rightabout, when this plate shape filling is assembled in stuffing rectification column and forms filling batch, enter gas-liquid fluid in stuffing rectification column in the gas-liquid two-phase counter-current flow process of layer and interlayer, light gas can move upward along lateral opening straight line, heavy liquid is along lateral opening linear downward motion, gas-liquid flux is improved with this, but although this structure not easily blocks, but mass-transfer efficiency declines.
Patent CN1054018 discloses two kinds of pulse corrugated fillers, and a kind of is pulse corrugated filler with waveform pulse cell cube, is characterized in: concavo-convex pulse unit body be ordered in continuously and in the same manner wavy channel domatic on.Another kind is the pulse corrugated filler with fusiformis pulse unit body, and be characterized in that the recessed cell cube of fusiformis pulse is arranged on the crest line of crest discontinuously, the convex cell cube of fusiformis pulse is arranged on the crest line of trough discontinuously.The first filler above-mentioned utilizes concavo-convex cell cube to realize gas-liquid shrinkage expansion motion to a certain degree near close filler corrugated surface, but the complex manufacturing process of filler, filling intensity is poor, cannot eliminate packing layer interfacial resistance; The second filler is substantially identical with common structured packing structure, only at filler peak, paddy place utilizes local deformation to produce the local turbulence of gas-liquid, to raising packing efficiency without substantial role.
Therefore, the structured packing structure of development of new, solves current structured packing Problems existing in actual applications, has very important significance for raising mass-transfer efficiency.
Summary of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, provides the structured packing of a kind of date core shaped grating type.A kind of date core shaped grating type of the present invention structured packing is compared with existing structured packing, there is mass-transfer efficiency high, structure is simple, volume is little, ant-scaling, pressure drop is little, the feature that after mass transfer reaction, gas phase liquid foam entrainment is few, be applicable to gas-liquid mass transfer and course of reaction, be particularly useful for high ash-laden gas and the process of process tail gas dust-removal and desulfurizing, the field such as petrochemical industry and environmental protection can be widely used in.
