Description
Technical field
The present invention relates to a kind of filler, relate in particular to a kind of structured packing of adopting composite to make, be mainly used in the gas-liquid environment, as the carrier of gas-liquid mass transfer.
Background technology
The structured packing of present industrial application mostly is ripple packing greatly, and it is to be assembled by a plurality of individual layer corrugated filler tablets.Ripple packing can be divided into screen waviness packings, mellapak packing, pulse corrugated filler etc. by structure, and its material has the branch of papery, metal, plastics and pottery etc. again.
200410080055.4 " screen waviness packings " of Beijing University of Chemical Technology laminate the silk netting that becomes to have crack structure by two-layer above silk screen, stack by the multi-layer silk screen sheet and to constitute the multi-layer silk screen structure, the broken-line type ripple crest line that the projection of arranging is arranged on the silk netting simultaneously, there are layer crack and space, silk screen hole to interact, make liquid form more liquid film on the silk screen surface, improve the moistening degree of silk screen, increased effective mass transfer area.
89202326.0 " the orifice plate micropore ripple packing structures " of Chemical Plant, Gaoqiao Petrochemical Industry CO., Shanghai City are similar with wire mesh packing, but it is to replace the corrugated metal silk screen with the ripple substrate that has aperture and micropore and microgroove, to improve the wetness degree of liquid at filling surface.
200820163361.8 " the calendering hole ripple packings " of Wu Jiadong, form by the calendering hole corrugated plate more than two, this calendering hole corrugated plate is the waveform that has ripple, each rolls hole corrugated plate mutual superposition, ripple direction on adjacent two calendering hole corrugated plates is opposite, described calendering hole corrugated plate is provided with more than one central through hole, is connected with the hole sheet around this central through hole, and this central through hole is evenly distributed on the corrugated plate of calendering hole.This structure has increased voidage and specific area, helps to improve gas-liquid mass transfer efficient.
90110083.8 " pulse corrugated fillers " of University Of Tianjin are pressed into the pulse ripple plate that has the convex-concave cell cube with plastics or sheet metal, and then are assembled into filler body formation pulse corrugated filler by certain rule.
Industrial application also have a kind of papery ripple packing, be paper material to be pressed into corrugated plate carry out bonding formation structured packing with glue again.Its surface is easy to by liquid wetting, and liquid has preferably evenly distribution performance on its surface, and corrosion-resistant.
Above-mentioned filler all is to wait and increase the uniformity that liquid distributes at filling surface by suppress various apertures, microgroove or convex-concave structure at material surface, to increase the gas-liquid heat exchange area.But because material itself all is hydrophobic, current are difficult to uniform spreading at material surface, but flow down in the mode of water droplet or one-tenth thigh, so the effect that increase gas and liquid contact surface amass and not obvious, heat and mass efficient is lower, also is prone to the liquid phenomenon of wafing of air supply direction.
The filler of metal material is corrosion-resistant then, can not use for a long time in acidity, alkalescence and salting liquid environment.
Paper material not only has smell, intensity difference, and in liquid environment, use for a long time and also glue dissolving/decomposition can occur, the packing sheet atrophy, loose, fall phenomenon such as slag.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of heat and mass efficient height, corrosion-resistant, intensity good, the surface be easy to wetting and can make liquid by liquid at its surperficial equally distributed packing sheet and filler, with from changing the heat and mass effect of filler in essence.
For achieving the above object, packing sheet provided by the present invention comprises the strength support layer, it is characterized in that also comprising that one is compound in the hydrophilic layer of strength support laminar surface.
Described hydrophilic layer can be compound in the one or both sides of strength support layer.Preferably, all be compounded with hydrophilic layer on the two sides of described strength support layer.
Described hydrophilic layer material can for example be one or more in hydrophilic nonwoven fabrics, hydrophilic resin, hydrophilic coating or the flocking.Preferably, described hydrophilic layer material is the water imbibition water wetted material, is more preferably the hydrophilic cloth of water imbibition.The water wetted material of water imbibition described in the present invention refers to material itself can be by the water wetted material that water soaked into.The hydrophilic cloth of described water imbibition for example is hydrophilic nonwoven fabrics, cotton, hydrophilic nonwoven fabric or the like.Further preferred, described hydrophilic layer material is hydrophilic nonwoven fabrics or hydrophilic nonwoven fabric.
Preferably, the packing sheet surface is corrugated.Preferred, the axis of described ripple both out of plumb also is not parallel to the edge of packing sheet.Preferred, the angle at the axis of described ripple and packing sheet edge is between 15 °-75 °.Preferably, described ripple height is 4-10mm.Preferably, described bellows-shaped is V-type, U type or sinusoidal waveform, more preferably sinusoidal waveform.Described packing sheet can adopt the thermoforming pressing mode corrugating of plastic uptake, mold pressing or roll-in.
Preferably, the described strength support layer hydrophilic layer surperficial with it adopts pouring film, spray glue or hot melt compound.
The layer of strength support described in the present invention mainly is to provide certain intensity for packing sheet.What preferably, described strength support layer adopted is high temperature resistant, corrosion resistant plastic material.The thickness of preferred described strength support layer is 0.1mm-1.5mm.More specifically, the material of described strength support layer employing is thermoplastic or plastic alloys such as PP, PE, PVC, ABS, PC.
The present invention also provides a kind of filler, it is characterized in that it is a plurality of by fixedly assembling according to above-mentioned arbitrary described packing sheet.
Preferably, in the described filler, the ripple axis is not parallel to each other between adjacent two packing sheets.
In the described filler, the fixedly assembling mode between described a plurality of packing sheets can adopt modes such as the series connection assembling of punching, the outside framework assembling is fixing, band is locked, strap is tied up.
Compared with prior art, the present invention has following advantage:
1) the packing sheet surface has hydrophilic layer, makes liquid at filling surface the good homogeneous distributivity be arranged, and has bigger gas-liquid contact area, improves mass-transfer efficiency;
2) when hydrophilic layer adopt be the water imbibition water wetted material time because hydrophilic layer itself can be by water infiltration, itself just can preserve certain quantity of fluid, can further increase the gas-liquid contact area, the raising mass-transfer efficiency;
3) when described water imbibition water wetted material adopt be the hydrophilic cloth of water imbibition the time, hydrophilic cloth itself is except that preserving the certain quantity of fluid, its surface also has countless micropores, has further increased the gas-liquid contact area, the raising mass-transfer efficiency;
4) independently strength support layer is arranged in the packing sheet, so all directions all have good intensity, using in liquid environment for a long time not can atrophy, and packing sheet is high temperature resistant, corrosion-resistant, can be used in the environment such as acidity, alkalescence, salting liquid;
5) the special device that is connected and fixed is arranged in the filler, ensureing can be not loose in the use;
6) nontoxic, free from extraneous odour is the novel environment-friendly product.
