Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment: see Fig. 1, the suppression gas fractionation unit that the present embodiment provides blocks the novel packed tower of liquid, comprise the cylindrical shell 1 of packed tower, the anti-swirl baffle 14 being arranged at the wire mesh demister 3 in cylindrical shell 1, packing layer, liquid header from top to bottom and being arranged at the bottom of tower, its main feature is wire mesh demister 3 in cylindrical shell 1 and is provided with guide-plate type liquid phase distributor between packing layer, and described guide-plate type liquid phase distributor is that guide plate is communicated with slot type liquid phase distributor.
In embodiment, packed tower comprises one group of guide plate and is communicated with slot type liquid phase distributor 5,10.
See Fig. 2-4, guide plate is communicated with slot type liquid phase distributor and comprises distribution grid 5-6 and slotted disk, distribution grid 5-6 is provided with riser 5-5, riser 5-5 is provided with liquid-blocking cap 5-1, support 5-2, upper strata spray apertures 5-3 and lower floor spray apertures 5-4, and slotted disk is provided with connectivity slot 5-7, draining plate 5-8 and liquid distributing groove 5-9.
Embodiment device, also comprises the solution inlet port pipe 4 known by this field, hold-down grid 6, filler 7, screen 8, grid support device 9, top catch tray 11, bottom catch tray 12, feed tube 13, gas feed 2, sewage draining exit 15 etc.
The novel packed tower of embodiment is the mass transfer apparatus using the filler in tower as gas-liquid two-phase Contact component, belongs to continuous contact gas-liquid mass transfer (contact) equipment, and two phase compositions are along tower height consecutive variations, and under normal operating condition, gas phase is continuous phase, and liquid phase is decentralized photo.The tower body of packed tower is vertical cylinder always, and supporting plate is equipped with in bottom, and filler is to huddle or the mode of whole block is placed on support plate.Hold-down grid is installed, in case blown by ascending air in the top of filler.Liquid sprays filler from tower top through guide-plate type liquid phase distributor, and flows down along filling surface.Gas is sent at the bottom of tower, and after distribution device in gas-fluid (minor diameter tower does not generally establish distribution device in gas-fluid) distribution, be the space that adverse current continues through packing layer with liquid, on filling surface, gas-liquid two-phase close contact carries out mass transfer.
When liquid flows downward along packing layer, have gradually to the trend that tower wall is concentrated, the flow quantity near tower wall is increased gradually, form wall stream.Wall stream effect causes gas-liquid two-phase skewness in packing layer, thus mass-transfer efficiency is declined.Therefore, when packing layer is higher, need to carry out segmentation to described packed tower, centre arranges apparatus for redistributing.Liquid redistribution device comprises liquid header and liquid re-distributor two parts, and the liquid under the filler stream of upper strata, after liquid header is collected, delivers to liquid re-distributor, sprays on lower floor's filler after redistribution.
The Novel guide plate formula liquid phase distributor of embodiment is arranged on above described packing layer, and the two ends of each Novel guide plate formula liquid phase distributor are fixed on same plane.The advantages such as it is comparatively simple that described guide-plate type liquid phase distributor has structure, easy for installation, and pressure drop is little, anti-carries secretly, occupy-place is low, make gas and liquid distribution evenly.Be suitable for the conditions such as charging, side take-off and liquid collection distribute again simultaneously.It is the development of disc type liquid distribution trough, and has some advantage of tank type liquid distributor.Slotted disc type distributor is by rising gas cap, and riser, catheter and chassis form.Just be that up big and down small two arrange aperture and open at the top of rectangle riser and middle part respectively with the essential difference of disc type distributor, by special catheter, liquid imported the low gas velocity district of filling surface.Design adopts full-mesh formula first-stage tank and guide plate stream, adopt and add special support distribution groove structure.Described distributor can play the function of liquid collecting, distribution of gas, liquid distribution and side take-off simultaneously.Be equipped with flow-guiding type filler pressing and can make Novel guide plate formula gas-liquid distributor liquid distribution better effects if, antiblocking ability is strong, the sedimentation being more conducive to drop with the feature such as to be separated.Operating flexibility and the operational load of device are larger.
The present embodiment, by the transformation to packed tower internal structure, is widely used in the separator of the process gas in the fields such as chemical industry, oil refining, pharmacy and environmental protection; Because its operating flexibility is large, device stability is high, therefore has good application prospect.
It should be noted last that, above detailed description of the invention is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to the practical structures in example, but can modify to the technical solution of the utility model or equivalent replacement, should be those skilled in the art in common knowledge, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in right of the present utility model.
