Abstract
The utility model discloses a corrugated regular packing, which comprises a central packing arranged in a cylindrical manner. A peripheral packing which is arranged in a cylindrical manner and comprises a plurality of circular arc-shaped regular corrugated boards with the same center is arranged on the outer periphery of the central packing, and the radius ratio of the central packing and the peripheral packing is between 1 to 1.01 and 1 to 1000. The regular packing with the characteristics of the utility model can reduce the wall flow phenomenon very obviously, since the channel for diffusingthe liquid to the tower wall radially is eliminated.
Description
Technical field
The utility model relates to the packing technique field of field separation engineerings such as oil refining and chemical industry, and the utility model relates in particular to a kind of corrugated regular filler.
Background technology
Corrugated regular filler is because the symmetry on geometry; even, regular gas-liquid flow path can be provided; present the performance of low pressure drop, big flux and the high excellence of separative efficiency, in the separating of fields such as oil refining, chemical industry and environmental protection, mass transfer and heat-transfer equipment, obtained using widely.
United States Patent (USP) 4296050, the basic configuration of proposition regular corrugation filler is both formed a series of vertical placements, the straight plate of ripple parallel to each other, and the structure of the straight plate of typical ripple is shown in Fig. 1-2.On the straight plate of each ripple jagged crest and trough are arranged all, the ripple addendum angle is 90 degree, and the height of crest is h, the pitch of waves is 2b, the inclination corner of crest is S, and there are an inclination angle in ripple direction and vertical direction, and the ripple inclination angle equal and opposite in direction of adjacent straight Lamb wave card, direction are opposite.
From United States Patent (USP) 4296050 beginnings, numerous patents of applying for a large amount of relevant ripple packings mainly concentrate on the maintenance overall structure basis of invariable, open some otch or aperture on the corrugated plating surface, distribute and contact condition to improve fluid, thereby promote mass transfer; Perhaps make the ripple incline direction into vertical direction in charge end, reach the minimizing resistance, improve the purpose of flux, perhaps be with the cross section crest of triangle (claiming zigzag again) and trough change into the trapezoidal or similar Chinese character trapezoidal, that the top is circular arc " go into " and irregularly shaped, expectation reaches the reduction pressure drop, reduce resistance, raise the efficiency simultaneously.
But numerous improvement does not still solve the generation of the wall flow phenomenon of ripple packing.Wall stream is influence present structured packing, particularly regular corrugation filler, the most important reason of separative efficiency.Relevant studies show that whenever has 10% wall miscarriage life, and the decline of 5% left and right sides separative efficiency is just arranged.Therefore,, improve the separative efficiency of structured packing, particularly regular corrugation filler, important practical sense and economic benefit are arranged with thorough elimination wall stream.
For eliminating the wall flow phenomenon, Chinese patent CN1125673, China utility model patent CN2593895,2246534,2661304 grades propose the tower inner member that wall stream takes place that prevents of various similar structures, have the effect of certain minimizing wall stream, but can't avoid the generation of wall flow phenomenon in the practical application to greatest extent.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of generation that can reduce the wall flow phenomenon significantly is provided, and improves the corrugated regular filler of the efficient of separating.
In order to achieve the above object, the technical solution adopted in the utility model is:
Corrugated regular filler, it comprises the center filler that is the column type setting, be surrounded by the peripheral filler that column type is provided with that is that circular arc regular corrugation plate by a plurality of phase concentrics constitutes on the filler excircle of described center, described center filler and peripheral radius filler ratio are 1: 1.01-1: 1000.
Advantage of the present utility model is:
Adopt the utility model structured liquids not carry out the passage of radial diffusion to the tower wall, so, overwhelming majority liquid all flows in the concentric column body space of sealing, even the outermost layer filler that directly contacts is arranged with the tower surface, because the tower wall inboard that its crest is in direct contact with, the liquid that flows to the tower wall also is to flow along the crest direction, still can play certain gas-liquid mass transfer effect.Generally, for better reducing the generation of wall flow phenomenon, recommend to use the tower internals that prevents that wall stream from taking place.The various corrugated platings that use among the present invention can be opened some otch or aperture at corrugated surface, distribute and contact condition to improve fluid, thereby promote mass transfer; Perhaps make the ripple incline direction into vertical direction in charge end, reach the minimizing resistance, improve the purpose of flux, perhaps be with the cross section crest of triangle (claiming zigzag again) and trough change into the trapezoidal or similar Chinese character trapezoidal, that the top is circular arc " go into " and irregularly shaped, expectation reaches the reduction pressure drop, reduce resistance, raise the efficiency simultaneously.
In a word, have the structured packing of the utility model feature, liquid does not carry out the passage of radial diffusion to the tower wall, can very significantly reduce the wall flow phenomenon and take place.

The specific embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments.
Corrugated regular filler of the present utility model as shown in Figure 3-4, it comprises the center filler A that is the column type setting, on the filler A excircle of described center, be surrounded by the peripheral filler B that column type is provided with that is that circular arc regular corrugation plate by a plurality of phase concentrics constitutes, described center filler A and peripheral filler B radius ratio are 1: 1.01-1: 1000, preferably 1: 1.2-1: 12, further preferably 1: 2-1: 8.Described center filler is regular corrugation plate filler or random packing, on each corrugated plate of described regular corrugation plate filler crest, trough are arranged, each corrugated plate is erect and is placed, and ripple direction and vertical cube are to an inclination angle is arranged, the ripple inclination angle equal and opposite in direction of adjacent corrugations sheet, direction is opposite.The line of all homonymy crests of each corrugated plating of described peripheral filler is not a straight line, but has concentric circular arc line, and this circular arc line itself may be exactly a complete circumference, the perhaps part of circumference.Described peripheral filler is whole cylindrical structure or the cylindrical structure for being assembled into by a plurality of circular arc type regular corrugation plates.Described corrugated plate can adopt metal or plastics to make.The specific area with peripheral filler zone in filler zone, described center can be identical, also can be different, filler zone, preferred center specific area is greater than peripheral filler zone specific area, and the gas phase drag in so peripheral filler B zone can decrease, and helps phase concentrations and is more evenly distributed.In order better to reduce the generation of wall flow phenomenon, preferably can in every layer of structured packing, can select to use the various tower inner members that prevent that wall stream from taking place.
Further specify the effect that adopts the utility model structure below in conjunction with specific embodiment.
