The invention belongs in production processes such as chemical industry, oil, light industry, medicine, energy industry, in order to the filler mass transfer component in the packed tower of finishing unit processes such as rectifying, absorption, extraction.
Now in the production process, the widely used regular tower filler of packed tower mainly contains ripple type, grid type, plate-type, unit contact-type, around plurality of classes such as volume type and honeycomb types, the background technology the most approaching with the present invention is metal crimp court of a feudal ruler perforated plate corrugated filler and corrugated wire gauze packing.Characteristics such as the rolling metal perforated plate corrugated filler is one of high efficiency packing of generally acknowledging at present, and it has even fluid distribution, and effectively big the and resistance of mass transfer area is little still, during making, at first will be punched on metallic plate, press ripple then, processed complex, cost of manufacture height.Again because the plate face and the tower axle of rolling metal perforated plate corrugated filler are 45 ° of inclinations, so when liquid was flowed through the plate face, dirt easily deposited and results in blockage.Corrugated wire gauze packing has that voidage is big, specific area is big, the wetting advantage such as evenly of filling surface, but the relative rolling metal perforated plate corrugated filler of manufacturing procedure is more complicated, and cost is higher, and it need be weaved into silk screen earlier, reroll and make the ripple plate.In addition, corrugated wire gauze packing requires high to medium, as the unclean obstruction that just easily causes.Also can only adopt the way of Chemical cleaning in case need to clean, and can not adopt machinery to clean, bring certain auxiliary work thus.
The objective of the invention is to avoid the weak point of above-mentioned background technology, design a kind of rational in infrastructurely, processing is simple, the efficient regular tower filler that cost is low.This tower packing has that specific area is big, fluid is evenly distributed and distribution performance is good again on tower tray, and voidage is big, pressure drop is low, and is difficult for by characteristics such as dirt obstructions.
Purpose of the present invention reaches by following measure:
A kind of discoid ring arc regular tower filler be by some be width with the tower tray height, be benchmark with the tower internal diameter, successively along the diminishing chord length of tower tray circumference be length straight-flanked ring arc plate vertically, be arranged in parallel the cylinder of closely filling tower section; Its ring arc plate plate length direction dashes a series of semicircle bulge loop and semicircle scrobicular ring, and each oppositely stamps out a small half of ring in each convex-concave ring, leave between each row convex-concave ring connect and support usefulness, be plane muscle.
The present invention is further illustrated in conjunction with following embodiment and accompanying drawing thereof:
Fig. 1 is ring arc sheet structure partial perspective view;
Fig. 2 is ring arc plate partial elevation view;
Fig. 3 is ring arc plate partial top view,
Fig. 4 is ring arc plate partial side view;
Fig. 5 is the front view of discoid ring arc regular tower filling-material structure schematic diagram;
Fig. 6 is the vertical view of discoid ring arc regular tower filling-material structure schematic diagram:
Shown in Fig. 1,2,3 and 4, the high B (shown in Figure 2) that selects discoid ring arc regular tower filler is a width, selecting the sheet metal coiled material of thickness δ=0.15~0.30 millimeter (shown in Figure 3) is raw material, go out continuously with a series of semicircle open form bulge loop 1 and semicircle scrobicular ring 4 shown in Figure 1 by diel along the web length direction, and each oppositely stamps out a small half of ring 2 in each convex-concave ring, leave between each row convex-concave ring connect and support usefulness, be plane muscle 3, its width is e, prepares ring arc sheet material.Intercepting with the tower internal diameter more successively is benchmark, is some straight-flanked ring arc plates of length along the diminishing chord length of tower tray circumference.In Fig. 3, R represents that the radius of semicircle bulge loop 1 or semicircle scrobicular ring 4 promptly encircles the peak height of arc structured packing; δ is a sheet metal thickness; In Fig. 4, the width of semicircle bulge loop 1 and semicircle scrobicular ring 4 equates, represents with A; B represents the width of small semi-ring 2; L represents the arc length of small semi-ring 2.
The optimum value of the physical dimension relation of ring arc plate is:
The b value is chosen among 3~5mm
As shown in Figure 6,7 are ring arc plate; Then with straight-flanked ring arc plate 7 vertically, be arranged in parallel the cylinder of closely filling tower section, and it is fixing with metal tower tray hoop 8, also can fix with the method for welding, producing with B is height, the discoid ring arc regular tower filler 5 that diameter and tower internal diameter closely match.It is many to coil the littler then gas of high B speed change frequency, helps liquid and distributes and improve mass-transfer efficiency.But height B is too little, then can cause fluid resistance big, also serves trouble to mounting strap.The size Selection principle of the high B of discoid ring arc regular tower packing box is as follows:
1, the distribution again and the raising mass-transfer efficiency that help liquid.
Because the fluid adjacent trays intersection of flowing through, because of the variation of gas speed impels the redistribution of liquid, the number of times of variation is many more, helps mass transfer more.So from improving the mass-transfer efficiency aspect, dish is high the smaller the better.
2, help flowing of fluid, the resistance of generation is little.
When fluid is flowed through in each filler tower tray, because of passage keeps definite shape, so resistance remains unchanged substantially; And, produce turbulence when the variation of flowing through between the tower tray because of gas speed, and resistance also changes (increases) thereupon, and therefore, from reducing the fluid resistance this respect, the dish height but should not be too small, and is excessive to avoid producing resistance.
3, help the filling of filler.
Structured packing is whole earlier dish filling when the size of tower diameter is little, and under certain tower height numerical value, few more helping more of tower tray number installs.
Comprehensive above-mentioned requirements, it is comparatively suitable that the tower tray height is got 100~200mm.Get big value when tower diameter is big, vice versa.
