The Ying Teluokesi Intalox metal tower packing (IMTP) that Norton company of the U.S. produces, it has the concern that the advantages such as intensity is high, flux is large, efficiency is high, pressure drop is low cause various countries' Chemical Engineering circle.Because rectangular saddle ring adopts large window channel, there is the advantage that flux is large, pressure drop is low.In addition, the mass transfer channel of Intalox metal tower packing mostly is circular arc, is more conducive to gas-liquid distribution, mass-transfer efficiency is higher.But because its ratio of height to diameter is comparatively large, during gas-liquid mass transfer, gas is comparatively large around the average path of filler, limits mass-transfer efficiency and improves further; The turnup structure of filling surface, cause easy coking material easily to block filling batch, performance of anti-blockage is not good.For liquid-liquid extraction system, turnup structure also can cause the gathering of decentralized photo, and mass-transfer efficiency declines.
Flat-ring packing is on the basis of cascade ring, further reduction ratio of height to diameter, when making gas-liquid mass transfer, gas greatly reduces around the path of filler, and in addition, flat-ring packing is when loose heap, there is structured packing effect, filler is piled up can not intussusception, makes the linear contact lay between filler become point cantact, adds the space between filler, improve the flux of filler, reduce packing pressure drop.The regular effect of flat-ring packing, makes liquid distribution in tower comparatively even, effectively can suppress axial backmixing.In flat-ring packing axial rings, flux is large, and surrounding perisporium cross-flux is little, limits the further raising of its mass-transfer efficiency.
Summary of the invention
For advantage and the respective Problems existing of Intalox metal tower packing and flat-ring packing, the object of the invention is to propose two arc ring packings that a kind of flux is larger, mass-transfer efficiency is higher, pressure drop is lower.
The technical solution that above-mentioned purpose of the present invention is achieved is: a kind of two arc ring shape random packing, be integrated the metal flat ring of rolling, it is characterized in that: described metal flat ring is curved arc shape fin in body perisporium is provided with rectangular window and is connected with two minor faces of rectangular window, and interior curved arc shape fin both end sides respectively offers a rectangle miniature window, rectangle miniature window is connected with arc fin near one end of body perisporium and the other end is set to bending sensing in arc forms in even partition filler inside the sheet that lolls.
Further, described metal flat is equipped with a pair symmetrical rectangular window and interior curved arc shape fin thereof, and each interior curved arc shape fin be attached to respectively rectangle miniature window and in loll sheet.
Further, the body perisporium of described metal flat ring between rectangular window offers circular hole.
Apply the random packing of of the present invention pair of arc ring shape, the advantage compared with prior art had and effect are: this filler combines that Intalox metal tower packing flux is large, efficiency is high and flat-ring packing ratio of height to diameter is low, uniform gas-liquid distribution, filling time queueing discipline, there is the advantages such as structured packing effect.

Fig. 2 is the plan structure schematic diagram of random packing of the present invention.
Detailed description of the invention
For the structure and innovation essence that make random packing of the present invention are known understanding, the embodiment of just random packing of the present invention by reference to the accompanying drawings is below described in detail.
For the various filler of tradition Problems existing separately, the object of the invention is to propose two arc ring packings that a kind of flux is larger, mass-transfer efficiency is higher, pressure drop is lower
As depicted in figs. 1 and 2, this kind of two arc ring shape random packing, is integrated the metal flat ring of rolling, thickness can be adopted to be less than the thin steel band rolling of 1mm.Its feature structure is specifically: this metal flat ring is curved arc shape fin 2 in body perisporium 1 is provided with rectangular window and is connected with two minor faces of rectangular window, and interior curved arc shape fin both end sides respectively offers a rectangle miniature window, rectangle miniature window is connected with arc fin near one end of body perisporium and the other end is set to bending sensing in arc forms in even partition filler inside the sheet 3 that lolls.
From diagram, this metal flat is equipped with a pair rectangular window of symmetry and interior curved arc shape fin thereof, and each interior curved arc shape fin be attached to respectively rectangle miniature window and in loll sheet, gas-liquid is more evenly distributed.
In addition, the body perisporium of this metal flat ring between rectangular window offers circular hole 4, the flux of two arc ring shape random packing perisporium can be increased further.
Filler of the present invention is the compound of Intalox metal tower packing and flat-ring packing, and result of the test shows, this filler has following remarkable advantage.
1, two arc ring packing is compared with Intalox metal tower packing, the ratio of height to diameter of filler reduces 50% ~ 70%(such as, the ratio of height to diameter of model 50# Intalox metal tower packing is 0.8, and the ratio of height to diameter of the two arc filler of model 50# is 0.4), specific area adds 50% ~ 70%(such as, and the specific area of model 50# Intalox metal tower packing is 74.9m
2/ m
3, and the specific area of the two arc filler of model 50# is 130m
2/ m
3).And two arc ring packing has the effect of structured packing when loose heap, filler is piled up can not intussusception, improves liquid flow, suppresses axial backmixing.Thus two arc ring packing has higher mass-transfer efficiency.In addition, two arc ring packings eliminate the turnup structure of Intalox metal tower packing, avoid because flange exists the packing layer blocking produced, enhance anti-blocking.
2, two arc ring packing is compared with flat-ring packing, and on flat peripheral wall, perforated area increases one times, and flux obviously increases, and pressure drop obviously reduces.The tongue piece stretched in two arc ring improves the utilization rate of packing ring inner surface, enhances the gas-liquid mass transfer in ring, and mass-transfer efficiency is significantly improved.
3, two arc ring packing is compared with the Intalox metal tower packing of same model, and flux, pressure drop are substantially suitable, and mass-transfer efficiency improves 20% nearly.Compared with the flat-ring packing of same model, mass-transfer efficiency, flux improve about 10%, and pressure drop reduces 10% ~ 15%.
4, two arc ring packing eliminates turnup structure and also has higher mass-transfer efficiency for liquid liquid extraction plant.Because liquid-liquid transfer is different from the mechanism of gas-liquid mass transfer, the existence of flange not only can not play the function of dispersion, cutting decentralized photo, and dispersed phase drop can be assembled at flange place, becomes major diameter drop by small diameter drops, reduces mass transfer area, is unfavorable for mass transfer.
In sum, this pair of arc ring shape random packing that the present invention develops has that flux is high, pressure drop is low, mass-transfer efficiency is high, process the advantages such as simple.Its operating characteristic is obviously better than rectangular saddle ring, the flat-ring packing of model of the same race, promotes this kind of filler in commercial Application, will greatly improve disposal ability, the mass-transfer efficiency of device, and can obtain obvious economic benefit.
In addition to the implementation, the present invention can also have other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
