Abstract
The utility model discloses an it packs and regular packing to found hole multiaspect ripple stands hole pattern board (1) and comprises bottom plate (1.1) sum channel (1.2), passageway (1.2) be from top to bottom even interval arrangement of axis with bottom plate (1.1), founding the thick 0.1 -0.5 millimeter of hole pattern board (1) board, highly being the 10 -500 millimeter, the regional percent opening of upper end and lower extreme is 35% -95%, the regional 1 -9 millimeter that highly is in upper end, and the lower extreme is regional highly to be the 1 -9 millimeter, and middle part primary area territory percent opening is 70% -95%, upright hole pattern board (1) ripple slab (2) of being processed into, the crest height is the 1 -9 millimeter, two corrugated contained angles are 30 - 60, the ripple interval is the 7 -40 millimeter, it has overcome the shortcoming that liquid dwell time is short among the prior art, the percent opening is low, has the advantage that reduces the flow resistance.
Description
Technical field
The utility model relates to packing technique field, is related specifically to a kind of vertical hole multiaspect ripple packing, and the utility model also relates to the structured packing being made up of this kind of vertical hole multiaspect ripple packing.
Background technology
Structured packing through the development of more than 30 years, has been applied widely in fields such as petrochemical complex, chemical fertilizer industry, natural gas conditioning, air separation since proposing from the seventies in 20th century. relatively typical structured packing is metal sheet corrugated regular filler at present, when this kind of filler is used for the operation of the gas-liquid mass transfer such as rectifying or absorption, in filler, gas-liquid two-phase is generally counter current contact mass transfer or heat transfer, liquid phase is that film shape flows downward along filling surface, liquid film is when flowing, one side is gas-to-liquid contact face, another side is liquid-solid contact face, gas-to-liquid contact face is mass transfer surface, liquid-solid contact face is non-mass transfer surface, it is generally Laminar Flow with its flowing of the liquid of solid packing surface contact, and the existence of laminar sub-layer can affect the flow state of liquid film, and then affect gas-liquid mass transfer efficiency. in addition, owing to Mellapak packing internal gas flow is non-uniform flow, the friction between circulation passage overcrossing point place gas phase, makes pressure drop increase, and process cost improves. therefore, how by the mass-transfer efficiency that improves structured packing, the resistance to flow that reduces gas phase simultaneously, reduce pressure drop, thus the efficient structured packing of development of new becomes an important research direction.
For the shortcoming that existing utility model patent (ZL200810052976.8) exists, the liquid of its inside, there is fixing duration of contact and the residence time all very of short duration, and the resistance of gas phase is relatively big, and the shortcoming that percentage of open area is less than normal, mass transfer effect is on the low side.
Practical novel content
First object of the present utility model is to overcome the weak point of above-mentioned background technology, and proposes a kind of vertical hole multiaspect ripple packing.
The utility model founds Kong Likong multiaspect ripple packing, and described vertical hole web plate 1 is made up of base plate 1.1 and passage 1.2, and described passage 1.2 is arranged at even interval taking base plate 1.1 up and down as axis; The vertical hole thick 0.1-0.5 millimeter of web plate 1 plate is highly 10-500 millimeter, upper end and lower end area percentage of open area is 35%-95%, and upper area height is 1-9 millimeter, and lower end area height is 1-9 millimeter, and middle part main region percentage of open area is 70%-95%;The corrugated cardboard sheet 2 that described vertical hole web plate 1 is processed into, crest height is 1-9 millimeter, and the angle of two ripples is 30 °-60 °, and ripple spacing is 7-40 millimeter.
In technique scheme: described perforate is trapezoidal or circular arc.
In technique scheme: described web plate longitudinal section, vertical hole is waviness.
In technique scheme: described vertical hole web plate material is stainless steel, carbon steel, aluminium alloy, pottery or plastics.
2nd object of the present utility model is to propose a kind of structured packing being made up of above-mentioned vertical hole multiaspect ripple packing.
The structured packing of the utility model vertical hole multiaspect ripple packing, the packing box that it is made up of multiple vertical holes corrugated cardboard sheet 2, it is highly 20-300 millimeter.
The utility model has following technological merit: 1, adopting vertical orifice plate net materials to process, its gas passage is more penetrating compared with common plate ripple packing, thus low than common corrugated plate packing pressure drop. 2, due to the raising that the regional opening rate between two dish fillers is further, pressure drop can be reduced further, and effectively reduce the generation of wall stream. 3, owing to the existence of mesh makes the turbulence of liquid film strengthen, and contacting with gas phase in liquid film both sides, gaseous fluid is turned back back and forth in filler inside so that the bigger raising of gas-liquid mass transfer speed simultaneously such that it is able to effectively improve gas-liquid mass transfer efficiency. The advantages such as 3, filler of the present utility model has big flux, low pressure drop, high mass transfer efficiency, high material use efficiency, easy to process.

Embodiment
Below in conjunction with accompanying drawing, performance of the present utility model is described, but they do not form restriction of the present utility model, only for example. Simultaneously by illustrating that advantage of the present utility model will become clearly with easy to understand.
With reference to shown in Fig. 1-4: the utility model vertical hole multiaspect ripple packing, described vertical hole web plate 1 is made up of base plate 1.1 and passage 1.2, and described passage 1.2 is arranged at even interval taking base plate 1.1 up and down as axis; The vertical hole thick 0.1-0.5 millimeter of web plate 1 plate is highly 10-500 millimeter, upper end and lower end area percentage of open area is 35%-95%, and upper area height is 1-9 millimeter, and lower end area height is 1-9 millimeter, and middle part main region percentage of open area is 70%-95%; The corrugated cardboard sheet 2 that described vertical hole web plate 1 is processed into, crest height is 1-9 millimeter, and the angle of two ripples is 30 °-60 °, and ripple spacing is 7-40 millimeter; Described perforate is trapezoidal or circular arc; Described web plate 1 longitudinal section, vertical hole is waviness; Described vertical hole web plate material is stainless steel, carbon steel, aluminium alloy, pottery or plastics.
