Description
Technical field
The utility model relate to a kind of for refining oil, the filler in the field such as petrochemical industry, chemical industry, a kind of gas-liquid contact in the operations such as rectifying, absorption carries out the visual plant of mass-and heat-transfer; A kind of foam structured packing with inclination angle turnover has particularly been proposed.
Background technology
Structured packing is widely used in the various fields such as petrochemical industry, fine chemistry industry, environmental protection, medicine because having the advantage such as higher than random packing efficiency, pressure drop is little, flux is large.Structured packing is with even geometric figure, to arrange in tower, and a kind of rectifying column filler of neatly piling up, and its advantage has been to stipulate the stream of liquid phase fluid, channel, plume phenomenon have been improved, reduce pressure drop, increased gas-liquid contact area, promoted the efficiency of heat and mass.New and effective structured packing has more good performance and clear superiority, is the representative of distillation technique strengthening and energy-saving equipment.
Structured packing is due to the requirement of specific area, support structure, installation and liquid distribution, and mostly the structured packing of application is at present to adopt corrugated board structures, and its topmost structural parameters are specific area and ripple inclination angle.Unit volume filling surface is long-pending higher, and efficiency is higher, and flux is lower; Angle between ripple and horizontal plane is larger, and flux is higher, and efficiency is lower.
Due to structured packing self ripple struction, make corrugated regular filler aspect hydrodynamics, still have some problems.Conventionally the pressure drop of corrugated regular filler is mainly comprised of three parts: the friction that the gas-liquid of reverse flow produces in interface; The friction producing to each other in cross aisle in gas flow process; The drag losses that gas produces when the entrance of upper and lower two-layer filler intersection, filler wall place, filler corrugated plate of flowing through, outlet.Wherein latter two resistance accounts for 80% left and right of overall presure drop, however this part pressure drop to mass transport process without facilitation.Too high voltage drop value can limit opereating specification, the reduction mass-transfer efficiency of packed tower, thereby therefore need be optimized and further reduce filler pressure drop filler.And ripple inclination angle and channel shape, liquid spraying density, gas flow rate etc. have material impact to the pressure drop of structured packing.
Research shows, packing efficiency can pass through increasing specific surface area, improves gas-liquid contact mass transfer area, thereby obtains higher gas-liquid mass transfer efficiency, but increases the decline that reference area can bring the rising of filler pressure drop and process load simultaneously.At present also there is the filler of the forms such as double-deck silk screen, but also have the problem that pressure drop raises.CN1127675A has developed a kind of Wave ring packing, the local turbulence that utilizes the interior aligned identical of filler plate passage or the alternate fin of size to produce gas-liquid, to a certain degree can improve separative efficiency, still the while is because the existence of fin can make filler pressure drop raise to some extent.That CN102218293A discloses a kind of silicon carbide foamed ceramics corrugated structured and preparation method thereof and application, owing to adopting carbofrax material, a kind of three-dimensional network connectivity structure can be provided, thereby raising mass-transfer efficiency, but because material itself has porous, therefore the thickness of its filler unit plate can not be too small, otherwise intensity and making all have problems, so just brought under the prerequisite with conventional structured packing same structure, because filler unit thickness of slab has reduced the mobile passage of gas phase, thereby cause the rising of filler pressure drop.
In order to meet oil refining in modern age and the requirement of petro chemical industry to tower, tower packing should have following performance: have higher specific area, gas-liquid two-phase can fully contact, to guarantee higher separative efficiency; The mobile resistance of fluid is little, to reduce Pressure Drop, reduces energy consumption.
Summary of the invention
In order to develop a kind of and traditional corrugated plate regular packing, compare, can improve the structured packing that separative efficiency and pressure drop reduce or remain unchanged, the utility model has utilized has the structured packing that the material of foaming structure is made corrugated plate shape, thereby improve the contact area of gas-liquid in solid, in addition by being transferred in the inclination angle of this cystosepiment corrugated regular filler, reduce the pressure drop of this foam stuffing, thereby obtain a kind of foam structured packing of inclination angle turnover of high efficiency low pressure drop, realize pressure drop reduce or the prerequisite that remains unchanged under improve the efficiency of packed tower.
The technical solution of the utility model is as follows:
A foam structured packing for the inclination angle turnover of high efficiency low pressure drop, its foaming structure is pencil, spongy or irregular porous foam structure, and in a structured packing, has the turnover at one or more ripples inclination angle.
There is the variation at ripple inclination angle for the crest of structured packing or trough in the turnover of described inclination angle, than the ripple inclination angle increase 5-70 ° of former ripple and horizontal plane angle.
Described inclination angle turning angle can be identical, also can be different.
In a unit of structured packing, the spacing of a plurality of inclination angles turnover can be identical, also can be different.
The pore volume mark 10%-90% of described porous foam structure, aperture 0.1-5mm.
Described filler unit height is 50-500mm.
During use, for identical filler unit height, can the requirement for efficiency and pressure drop according to practical operation, select different inclination angle turnover number and angle, such as, meet under the prerequisite of pressure drop requirement and pursue number and the angle that efficiency can suitably reduce turnover.That is to say that foaming structure itself can increase separative efficiency, but due to the requirement of its aperture to thickness, the increase of thickness can make its pressure drop meeting rise to some extent, if maintain high separative efficiency and pressure drop, does not increase, and just can suitably increase number and the angle of inclination angle turnover.
The utlity model has following advantage, utilized the material with foaming structure to make structured packing, thereby improve the contact area of gas-liquid in solid, improve mass-transfer efficiency; Simultaneously, by being transferred in structured packing inclination angle, the local angle increasing between filler inclination angle and horizontal plane, thereby can offset or reduce this foam stuffing because thickness of slab causes the pressure drop of the filler that gas-phase space reduces to produce, thereby obtain a kind of foam structured packing of inclination angle turnover of high efficiency low pressure drop, realize pressure drop reduce or the prerequisite that remains unchanged under improve the efficiency of packed tower.
