A kind of high efficiency separation packed tower
[technical field]
The present invention relates to the technical field of packed tower, the technical field of a kind of high efficiency separation packed tower.
[background technology]
Packed tower is the one of tower.The filler of suitably height is filled, to increase between two kinds of fluids in tower
Contact surface.Such as when being applied to GAS ABSORPTION, liquid is entered by distributor by the top of tower, along filler
Surface declines.Gas is then sailed against the current by filler hole by the bottom of tower, with liquid close contact and mutual
Effect.Structure is relatively simple, overhauls more convenient.Be widely used in GAS ABSORPTION, distill, the operation such as extraction.
Tower internals is the ingredient of packed tower, and it collectively forms a complete packed tower with filler and tower body.Institute
The effect of some tower internals is provided to make gas-liquid better contact with in tower, in order to play the maximum of packed tower
Production capacity and maximal efficiency, liquid distribution trough belong to filler in a kind of tower internals, therefore liquid distribution
The quality of separator directly affects playing and the performance of whole packed tower of carrier performance.
Packing ring focuses primarily in packed tower, as the mass transfer apparatus of contact member between gas-liquid two-phase, it is adaptable to
At the separation of various gases, absorption, desorption device, synthesis ammonia decarburization, desulphurization system, ethylbenzene separation, toluene
Separate.Common metal packing ring and common fillers ring are big because of weight, window impeller structure and the machine of ring body structurc
Tool intensity is low, yielding during stacking, easily forms dead angle in tower, and space is discontinuous, causes fluid resistance
Bigger flux is relatively low, easily causes gas-liquid channel, causes flux to reduce, and pressure drop raises, and separation efficiency reduces.
Structured packing is that one is arranged by uniform geometric figure in tower, the filler neatly piled up.Owing to having
Specific surface area is big, pressure drop is little, fluid divides uniformly, mass-and heat-transfer efficiency advantages of higher, has therefore obtained extensively
Application.Develop the earliest is metal structured packing, and that the most in succession develops has plastic regular packing material, pottery
Structured packing and carbon fibre regular filler.Orifice plate filler is the one in structured packing, existing orifice plate filler
Using single-side holed structure, the through-hole aperture that orifice plate is processed to form is relatively big, and the mechanical strength of orifice plate is relatively low,
Two through-hole apertures using hydraulic pressure to be processed to form are too small, and convection effects is poor, and pressure drop is big, and fluid distrbution is uneven,
Have a strong impact on separating effect.
[summary of the invention]
The purpose of the present invention solves the problems of the prior art exactly, proposes a kind of high efficiency separation packed tower, liquid
Body distributor has bigger mass transfer, the effective surface area of heat transfer, and liquid distribution is uniform, it is possible to change greatly
Contact between kind liquid phase, air resistance is little, and operation pressure drop is low, and compact conformation takes up space in tower
Little, thus improve the efficiency of tower, random packing ring quality is relatively light, and window impeller structure and outer ring body structure have relatively
High mechanical strength, is not easily formed dead angle during stacking, space is continuous, and fluid resistance relatively small throughput is higher, subtracts
Few gas-liquid channel, it is possible to effectively reduce pressure drop, separation efficiency improves, and it is strong that filler orifice plate has good machinery
Degree, and convection effects is good, mass-and heat-transfer efficiency is high, uniform gas-liquid distribution, improves separation efficiency.
