Abstract
The utility model discloses a nozzle baffle type tower plate which consists of a horizontal tower plate 10, injection cylinders 2, holding frames 8 and separating plates 9, wherein, the horizontal tower plate 10 and a downcomer 4 are arranged inside the tower wall 1; three rows of arc-shaped nozzle air lifting holes 7 are arranged on the tower plate; each injection cylinder 2 is arranged on an appropriate position of each air lifting hole; a liquid separating barrier 3 and a guide plate 11 are arranged on the upper edge of the injection cylinder; a bottom spacing 5 is arranged between the injection cylinder and the tower plate; the separating plates 9 are respectively arranged on the lower part of the air lifting holes through the holding frames 8; each separating plate consists of two flat plates; and the vapor phase entrainment of the tower plate is 5 percent lower than that of F1 floating valve tower plate. The utility model is adequate for various mass transfer and heat transfer towers and is particularly adequate for the distillation process for decompression.
Description
The utility model relates to the column plate in mass transfer in a kind of chemical industry, the heat transfer plate column.
At present, employed column plate majority is bubble column, valve tower, sieve-plate tower etc. in processes such as the distillation of chemical industry, absorption, desorb, humidification.The disposal ability of these column plates is little, and pressure drop is big.In recent years, some novel column plates have appearred, as vertical sieve tray, though all be significantly improved at aspects such as disposal ability, efficient, but plate pressure drop still is higher, and plate efficiency is high not enough, and industrial application also only limits to some specific industry, for the still-process of decompression operation, powerless especially.New packing invention and use, though improved separative efficiency, aspect the raising disposal ability, but significantly not progressive.
The objective of the invention is to overcome weak point of the prior art, a kind of low pressure drop, big flux, high efficiency nozzle baffle-type jet tray are provided, this column plate not only can significantly improve the disposal ability of tower, and plate pressure drop is low, and mist entrainment is little, the plate efficiency height, and can be used for decompression operation.
Technical solution of the present invention is as follows:
Nozzle baffle type tower tray is made up of horizontal column plate, spraying canister, bracing frame and separating plate, in tower, adorning horizontal column plate, have camber nozzle air rising hole on the column plate, spraying canister is being adorned in the corresponding position of each air rising hole, the top edge of spraying canister is provided with guide plate, crack, the end is arranged between spraying canister and the column plate, and the below of air rising hole is provided with separating plate, and separating plate can be flat board, screen, mesh plate, silk screen etc.
The present invention compared with prior art has following advantage: this nozzle baffle type tower tray is after having camber nozzle air rising hole, its plate pressure drop has only the 30%-50% of F1 valve plate pressure drop, and its gas phase mist entrainment is less than 2% when the void tower kinetic energy factor reaches 3.0.
The utility model is described in further detail below in conjunction with specific embodiment.
Fig. 1 is the nozzle baffle type tower tray structural representation;
Fig. 2 is the layout viewing of nozzle baffle type tower tray in tower.
Fig. 1, nozzle baffle type tower tray shown in Figure 2 are made up of horizontal column plate 10, spraying canister 2, bracing frame 8 and separating plate 9, in tower wall 1, adorning horizontal column plate 10 and downspout 4, have three row's camber nozzle air rising holes 7 on the column plate, adorning spraying canister 2 in each air rising hole corresponding position, the spraying canister top edge is provided with liquid-separating grid 3 and guide plate 11, space, the end 5 is arranged between spraying canister and the column plate, adorning separating plate 9 by bracing frame 8 respectively below air rising hole, separating plate is by two dull and stereotyped compositions.
The operation principle of nozzle baffle type tower tray is: liquid flows down from the downspout of last layer column plate, gas enters in the spraying canister by air rising hole from the below of column plate, when in gas enters spraying canister, rising, liquid crack at the bottom of the spraying canister is sucked in the spraying canister, and pulled into liquid film by gas, liquid film is broken into drop under the surface tension of liquid effect.Drop is under the drive of gas, by the liquid-separating grid ejection of open spraying canister top and top edge.Under the effect of guide plate, after the gas-liquid two-phase self-injection tube ejection, the space disperses once more strongly to spray in tower, and vectored injection, avoids or has reduced back-mixing, has improved plate efficiency, makes that the space utilization rule reaches more than 80% in the tower.The drop of ejection is beaten on the separating plate of frame dress below the last layer column plate air rising hole with gas in the spraying canister, and droplet is polymerization on separating plate, with the bearing of trend ejection of gas along separating plate, finally falls back on the column plate.The Open architecture of nozzle baffle type tower tray makes gas flow more unobstructed, has improved disposal ability; Camber nozzle air rising hole has reduced plate pressure drop, and separating plate has effectively prevented entrainment, has improved mass-transfer efficiency.
The utility model the experiment proved that: the dry plate resistance and the liquid that need overcome column plate itself when the air communication of rising is crossed column plate promotes, broken energy loss of spraying has formed plate pressure drop.In liquid handling amount one regularly, along with the increase of uprising gas speed, gas meeting entrained liquids is to upper strata column plate, i.e. entrainment.Experimental results show that: because the gas phase of nozzle baffle type tower tray is by passing through in the spraying canister, and liquid phase is passed through by cover is outer, so gas need not overcome the static pressure of liquid layer by this column plate the time, makes plate pressure drop very low like this.Because the centrifugation of separating plate when the void tower kinetic energy factor reaches 3.0, does not have obvious entrainment, has improved mass-transfer efficiency.
