Abstract
The invention discloses a kind of vertical hole multiaspect ripple packing and structured packing, vertical hole pattern plate (1) is made up of bottom plate (1.1) and passage (1.2), and described passage (1.2) is that axis up and down arrange by uniform intervals with bottom plate (1.1)；Vertical 0.1 0.5 millimeters of hole pattern plate (1) thickness of slab, is highly 10 500 millimeters, and upper end and lower end area percent opening are 35% 95%, and upper area highly is 19 millimeters, and lower end area highly is 19 millimeters, and middle part main region percent opening is 70% 95%；The corrugated cardboard sheet (2) that described vertical hole pattern plate (1) is processed into, crest height are 19 millimeters, and the angle of two ripples is 30 ° 60 °, and ripple spacing is 7 40 millimeters；It overcomes the shortcomings that liquid residence time in the prior art is short, percent opening is low, has the advantages of reducing fluid resistance.
Description
Technical field
The present invention relates to packing technique field, is related specifically to a kind of vertical hole multiaspect ripple packing, the invention further relates to
The structured packing being made up of this vertical hole multiaspect ripple packing.
Background technology
Since structured packing proposes from the 1970s, by the development of more than 30 years, in petrochemical industry, chemical fertilizer work
The fields such as industry, natural gas purification, air separation are applied widely.It is at present metallic plate ripple than more typical structured packing
Structured packing, when this filler is used for the operation of the gas-liquid mass transfers such as rectifying or absorption, gas-liquid two-phase generally countercurrently connects in filler
Mass transfer or heat transfer are touched, liquid phase flows downward along filler surface in membranaceous, and liquid film is simultaneously gas-liquid contact face, separately in flowing
It is simultaneously liquid-solid contact face, gas-liquid contact face is mass transfer surface, and liquid-solid contact face is non-mass transfer surface, is contacted with solid packing surface
Its flowing of liquid is generally Laminar Flow, and the presence of laminar sublayer can influence the flow regime of liquid film, and then influences gas-liquid and pass
Matter efficiency.Further, since mellapak packing internal gas flow is in non-uniform flow, between gas phase at circulation passage overcrossing point
Friction, increases pressure drop, and operating cost improves.Therefore, how by improving the mass-transfer efficiency of structured packing while reducing gas phase
Flow resistance, reduce pressure drop, turn into an important research direction so as to develop new and effective structured packing.
The shortcomings that existing for existing patent of invention (ZL200810052976.8), its internal liquid, there is fixation
The shortcomings that time of contact and residence time are all very of short duration, and the resistance of gas phase is larger, and percent opening is less than normal, mass transfer effect is relatively low.
The content of the invention
The first object of the present invention is the weak point for overcoming above-mentioned background technology, and proposes a kind of vertical hole multiaspect ripple
Filler.
The vertical Kong Likong multiaspect ripple packings of the present invention, described vertical hole pattern plate 1 is made up of bottom plate 1.1 and passage 1.2, described
Passage 1.2 with bottom plate 1.1 be axis above and below uniform intervals arrange；The vertical thickness of slab 0.1-0.5 millimeters of hole pattern plate 1, are highly 10-
500 millimeters, upper end and lower end area percent opening are 35%-95%, and upper area is highly 1-9 millimeters, and lower end area is highly
1-9 millimeters, middle part main region percent opening are 70%-95%；The corrugated cardboard sheet 2 that described vertical hole pattern plate 1 is processed into, crest height
For 1-9 millimeters, the angle of two ripples is 30 ° -60 °, and ripple spacing is 7-40 millimeters.
In the above-mentioned technical solutions：Described perforate is trapezoidal or circular arc.
In the above-mentioned technical solutions：Described vertical section bellows-shaped is waveform.
In the above-mentioned technical solutions：Described vertical hole pattern plate material is stainless steel, carbon steel, aluminium alloy, ceramics or plastics.
The second object of the present invention is to propose a kind of structured packing being made up of above-mentioned vertical hole multiaspect ripple packing.
The structured packing of the vertical hole multiaspect ripple packing of the present invention, the packing box that it is made up of multiple vertical hole corrugated cardboard sheets 2, its
Highly it is 20-300 millimeters.
The present invention has following technological merit：1st, it is process using vertical orifice plate net materials, its gas passage is compared with common plate
Ripple packing is more penetrating, thus lower than common corrugated plate packing pressure drop.2nd, because the regional opening rate between two disk fillers is entered
The raising of one step, pressure drop can be further reduced, and effectively reduce the generation of wall stream.3rd, because the presence of mesh causes liquid film
Turbulence is strengthened, and is contacted simultaneously with gas phase in liquid film both sides, and gaseous fluid is turned back back and forth inside filler so that gas-liquid mass transfer speed
The larger raising of rate, so as to effectively improve gas-liquid mass transfer efficiency.3rd, filler of the invention has big flux, low pressure drop, Gao Chuan
Matter efficiency, high stock utilization, it is easy to process the advantages that.
