The specific embodiment
The float valve tray of the utility model design, its structure such as Fig. 1, Fig. 2 and shown in Figure 3 comprise column plate 5, down-flow plate 7, float valve 4, bubbling promoters 3 and seal pot 2; Column plate 5 places the central authorities of tower body, and seal pot 2 places a side of column plate 5, has air rising hole 31 on the seal pot 2, and bubbling promoters 3 covers on the air rising hole 31 of seal pot 2, and down-flow plate 7 places the opposite side of column plate, and down-flow plate 7 constitutes downspout 8 with tower wall 1.
The structure of float valve is made up of valve face 9 and valve leg as shown in Figure 4 and Figure 5, and 1～6 bridge shape projection 10 is arranged on the valve face, three of projection are separated with valve face 9, one side links to each other with valve face, the middle part protuberance, and bump height is 5～8mm, form hole 11 between protuberance and the valve face, the hole highest point is 1～5mm, and this hole becomes gas passage, and the valve leg comprises liquid-facing side valve leg 13 and downstream valve leg 14, liquid-facing side valve leg 13 hangs down 0～3mm than downstream valve leg 14 wide 0～10mm.The float valve tray of the utility model design, at the air-locked problem of traditional float valve valve face, backed down 1～6 bridge opening at the float valve valve, therefrom level ejection of air-flow, form countless micro-bubbles, as shown in Figure 6 and Figure 7, for the contact of gas-liquid two-phase provides a large amount of mass transfer surfaces long-pending, therefore improved mass-transfer efficiency; Reduce the air velocity of ejection in valve edge 12 simultaneously by the air-flow of ejection in the slit 11, thereby reduced entrainment.The design of special valve leg makes air-flow produce thrust, promotes liquid and advances with certain direction, makes float valve of the present utility model have guidance quality to liquid.Three supporting legs of the circular float valve of tradition are uniformly, air-flow to around homogeneous radiation, and the width of valve leg of the present utility model just is different.Meet the valve leg that comes flow path direction in the upstream and remove the wide 5～10mm of valve leg width of flow path direction, highly low 0～3mm than the downstream.From mechanical analysis as can be known, this makes air-flow promote liquid downstream and quickens to flow (being guide effect), thereby can reduce the liquid layer thickness on the column plate, and minimizing is carried secretly, and production capacity is improved; Eliminate fluid stagnation district on the tower tray, liquid stream is evenly distributed, reduce back-mixing, thereby efficient is improved.
The valve face of the float valve in the above-mentioned float valve tray is circle or rectangle, as shown in Figure 4 and Figure 5, when the valve face of float valve is rectangle, has pore 15 on the downstream valve leg of float valve.When the valve face of float valve when being circular, the float valve hole 16 on the column plate has the anti-projection 17 of revolving, and circular float valve can not be rotated, thereby avoids wearing and tearing and cause float valve to come off, as shown in Figure 8.
The utility model has designed the bubbling promoters, and this is that it is few to contain bubble because of the liquid that flows into column plate from downspout, the static pressure height, easy-to-leak liquid, mass transfer is bad, and the effect of bubbling promoters is an attenuate import liquid layer, reduce hydraulic shock, and the formation negative pressure, make the easier liquid layer that enters of air-flow that it is blown pine thus, form bubbling, enlarge the area of air-flow contact, improved mass-transfer efficiency.Use the bubbling promoters can also eliminate the entrance region leakage, make full column plate liquid layer even, help raising the efficiency, improve production capacity, increase operating flexibility.A kind of structure of bubbling promoters as shown in Figure 9, strike out a ∏ shape platform 18 by lath, high 16～the 30mm of platform, table top has valve opening 16 or sieve aperture 32, the updrift side of platform is found a baffle plate 19, baffle plate exceeds table top 16～30mm, and ∏ shape platform covers on the air rising hole 31 of seal pot 2.When liquid flows to the bubbling promoters in downspout after, be subjected to the effect of baffle plate 19, cross baffle plate 19, its rear portion forms negative pressure.Simultaneously, because table top has certain altitude, make liquid layer attenuation on it, thereby reduced the static pressure of liquid.This two effect all makes the gas of column plate below with the float valve of fast speeds by sieve aperture 32 or float valve hole 16, forms stronger bubbling, contains more bubble in the liquid thereby make, and the gas-liquid contact condition that is beneficial to bubbling promoters back is good.The high velocity liquid stream of having avoided simultaneously falling in the downspout has reduced the serious leakage in this place to the one or two impact of arranging float valve.Can make liquid be blown " pine " by gas in addition, make the liquid layer on the column plate more even once entering column plate.These have all improved mass-transfer efficiency and production capacity.The another kind of structure of bubbling promoters is a tapering shape bubbling promoters, shown in Figure 10 (a) and Figure 10 (b), by half six rib truncated cones 20, meet liquid level plug-in unit 21 and downstream plug-in unit 23 is formed, meeting liquid level plug-in unit 21 is connected with the big end of half six rib truncated cones 20, downstream plug-in unit 23 is connected with the small end of half six rib truncated cones 20, half six rib truncated cones 20 cover on the air rising hole 31 of seal pot 2, have the aperture 22 that diameter is 4～6mm on 3 faces of half six rib truncated cones and the downstream plug-in unit face.Because meeting liquid level stops the high-speed liquid that falls in downspout, make gas more easily from aperture 22, pass through to form bubbling.Near downcomer outlet port, be arranged in order many such tapering shape bubbling promoters, can play the effect of bar formula bubbling promoters simultaneously.
The column plate of the float valve tray of the utility model design is formed by connecting by polylith column plate 25.The structure that polylith column plate 25 connects as shown in figure 13, column plate structure such as Figure 11 and shown in Figure 12, the one side is provided with self beam 26, passage 27 and bar hole 28, opposite side is provided with boss 29, valve opening 16 and is connected tongue 30.The coupling part will take very large tracts of land on traditional column plate, this part does not have the air communication mistake, the gas-liquid contact condition is relatively poor, the production capacity and the efficient of column plate have been reduced, design feature of the present utility model is, opens valve opening in the column plate bonding pad, puts float valve, thereby overcome above-mentioned shortcoming, shortened installation work-hour.From Figure 11 and Figure 12 as can be seen, column plate 25 is the rectangle metal sheet, on long limit, rectangle left side self beam 26 is arranged, and offers the passage 27 of row's size greater than float valve by the float valve pitch of holes on the plate face of its top, on each passage 27 right side one bar hole 28 is arranged; Long limit is provided with a bridge shape boss 29 on the right side of rectangle column plate, and its height of projection equals thickness of slab, and position corresponding with above-mentioned passage 27 on the boss has float valve hole 16, and edge, long limit, right side has zigzag to connect tongue 30.Figure 13 is the scheme of installation of two blocks of column plates, installation is that the connection tongue 30 on the tray deck is inserted in the bar hole 28 of another piece tray deck that is complementary with it with 45 °～90 ° inclination angle, then with two tray deck horizontal, then connect tongue 30 and bar hole 28 and link mutually, boss 29 can make two tray decks connect thick height unanimity.Because of two plates tight pressings, its gap is very little, so easy-to-leak liquid not, this hinge joint also reaches very high strength, so can bear very big load.
The utility model makes improvements downspout entrance section shape, makes the long increase in weir, and overflow intensity reduces; The improvement of downcomer outlet port cross sectional shape increases column plate bubbling area area.This two measure has all improved the production capacity of high-effect column plate.
