According to the combined column plate, flow-through sieve plates, which have the same aperture ratio and arranged in a staggering way, are fixed at the upper part of the flow-through column plate with high aperture ratio; the whole combined column plate is arranged as individual blocks based on the H-shaped vertical side; the H-shaped vertical side serves as a supporting beam of the composite flow-through column plate; a vertical separating plate is added in an upper groove; the whole column plate is divided into a plurality of mixing tanks by the H-shaped vertical side and separating plates; the fiber bundle fillers which are 300 to 2500mm in height are positioned in a lower groove. With the adoption of the combined column plate, the space in the column is fully utilized, the vapor-liquid mass transfer condition of the flow-through column plate is improved, the pressure release of the column plate is reduced, the entrainment is reduced, the processing capacity of the flow-through column plate is improved, the operation flexibly and the separating efficiency are improved, a super-large supporting ring for the column plate is removed, the extreme demand on levelness in installation and the amplifying effect are also removed, the problem due to the large supporting structure of the column plate is solved as well as the problem due to the column plate, and large-scale columns are easy to obtain.
Description
Technical field
The present invention relates to separation equipment field, the combined type column plate of espespecially a kind of compound dual-flow tray and the coupling of fibre bundle filler.
Background technology
At industrial departments such as petrochemical industry, petroleum refining, chemical industry, light industry, environmental protection, medicine and atomic energy, column plate and filler are widely used in distillation, absorption, extraction, absorption, washing, the unit processes in chemical synthesis such as cooling.Filler has the advantages such as separative efficiency is high, pressure drop is little, disposal ability is large, but cost is larger, and operating flexibility is little, to supporting tower internals, requires high; Large, the anti-obstruction of operating flexibility of tray, cost is low, separative efficiency is relatively large, but pressure drop will be larger, and disposal ability is lower.Column plate is by having or not downspout can be divided into overflow-type column plate and throngh flowing type tray, and by contrast, existing throngh flowing type tray is simple in structure, and in tower, space availability ratio is high, and cost is low, and disposal ability is large, but vapour-liquid is short time of contact, and mass-transfer efficiency is low, and operating flexibility is little.Desirable tower internals should have low pressure drop, high efficiency, large operating flexibility, anti-obstruction, low cost, large disposal ability and the high characteristic of Ta Nei space availability ratio simultaneously.By column plate and filler compound be one of the effective way of tower internals of realizing ideal.Fibre bundle filler is the high surface linked network formula flexible filler that a kind of liquid phase of exploitation is recently continuous phase, and more than liquid flooding high cycle speed reaches 8m/s, mass-transfer efficiency is high, and pressure drop is only the 1/2-1/3 of common structured packing.
Compound overflow-type column plate compounded mix and the throngh flowing type tray compounded mix of mainly containing of column plate and filler, because throngh flowing type tray is simple in structure, it is compound to be easy to filler, is ideal column plate filler complex form.But existing dual-flow tray compounded mix, because the liquid flooding of structured packing is restricted the elasticity of composite plate and load-bearing capacity.The patent CN101480537 declaring as the inventor has mentioned a kind of novel turbogrid type composite column plate and has adopted the sieve plate that increases identical percent opening on dual-flow tray, the structured packing that one deck 0-250mm is high is set below dual-flow tray, make full use of Ta Nei space, increase air-flow time of contact, air-flow mixing intensity and interface renewal rate have been strengthened, improve plate efficiency, simultaneously due to the existence of sieve plate makes percent opening can be up to 60%, the disposal ability and the operating flexibility that have greatly improved column plate, reduced plate pressure drop and entrainment; Throngh flowing type tray serves as the liquid distribution trough of structured packing effectively, makes liquid laterally mix and reach the desired perfect condition of filler; Conversely, the gas distributor of column plate has been served as again in structured packing, further improves vapour-liquid mass situation, has rationally effectively utilized the advantage of column plate and filler.But because the liquid flooding gas speed of structured packing is lower, maximum void tower kinetic energy factor is less than 3(m/s) .(kg/m3)
1/2, become turbogrid type composite column plate and further carry high-throughout bottleneck.
Summary of the invention
