The utility model has the advantages of simple manufacture, labor and material saving, low cost, convenient installation with low requirements, high operating flexibility and extensive applicability, thereby being suitable to be used in liquid feeding devices of packed tower of various specifications during operation process such as gas-liquid mass transfer, separation and heat transfer in industrial production.

Description

Improve the wall stream liquid distributor of gas-liquid distributor flow quantity precision
Technical field
The utility model relates to a kind of wall stream liquid distributor that improves gas-liquid distributor flow quantity precision, belongs to packed tower internals device.
Technical background
The slotted disc type liquid distribution trough that uses in the packed tower, it comprises seal pot, that arranges on the seal pot rises air drain, offers liquid spraying hole and spout hole on frid, is provided with the liquid collecting board on the air drain rising.The course of work of this gas-liquid distributor in packed tower is: the liquid that is flowed down by gas-liquid distributor upper strata filler or feed tube in the packed tower flows on the seal pot, after liquid level reach a certain height, liquid is by in the spray apertures spirt mozzle that rises on the air drain frid, and flow to down thus on lower floor's filler of gas-liquid distributor, can reach the purpose that liquid distributes again.And from the gas that rises by gas-liquid distributor lower floor filler by the rising the upper strata filler that air drain rises to gas-liquid distributor of gas-liquid distributor, thereby realized the even distribution of gas-liquid; Dirty liquid directly drops on the liquid level of seal pot in this process because above the gas-liquid distributor, kinetic energy is bigger, make the liquid fluctuating on the seal pot very big, therefore cause that to rise on the air drain on the frid fluctuation of the flow quantity of each spray apertures big, inhomogeneous, differ bigger with design load, cause mass-transfer efficiency low.
Summary of the invention
The purpose of this utility model is to provide a kind of wall stream liquid distributor that improves gas-liquid distributor flow quantity precision.This liquid distributor is simple in structure, and its work has improved the flow quantity precision of gas-liquid distributor.
The utility model is realized by following proposal.A kind of wall stream liquid distributor that improves gas-liquid distributor flow quantity precision, this wall stream liquid distributor is arranged on the tower wall above the gas-liquid distributor in the tower, it is characterized in that it comprises the liquid-collecting bottom ring 2 that is connected with the tower wall, uniformly on it offer the liquid distributing hole that diameter is 10~30mm, the interior circle of liquid-collecting bottom ring 2 connects liquid-collecting inner tube 1, constitute the annulus liquid storing tank by liquid-collecting bottom ring 2 and liquid-collecting inner tube 1 and tower wall 6, is the draining plate 4 of 10-60 degree in the outer bottom setting of liquid-collecting bottom ring 2 towards the inclination angle that tower wall direction tilts, the annulus liquid storing tank with pass through the feed tube 3 that is connected on the tower wall 6 and be communicated with.
The utility model has the advantages that and make simply that saving of labor, material-saving cost are low; Simple installation requires low, and the operating flexibility scope is wide, and applicability is strong.Can be used in the feeding device of the packed tower of all size in the operating process such as gas-liquid mass transfer in the industrial production, separation, heat transfer.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing of the A of Fig. 1.
Fig. 3 the utility model is installed in the working state schematic representation in the packed tower.
Among the figure: 1 is liquid-collecting inner tube, and 2 is liquid-collecting bottom ring, and 3 is feed tube, and 4 is draining plate, and 5 is the erosion control ring flat-plate, and 6 is the tower wall, and 7 is wall stream liquid distributor of the present utility model, and 8 is slotted disc type gas-liquid distributor.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, the decarbonizing tower of certain synthesis ammonia plant, diameter is 4000mm, adopts the CO in the NHD solution suction conversion gas on the technology 2, the solution internal circulating load is 950m 3/ h, liquid hollow-spraying-tower density reaches 75m 3/ m 2H requires to absorb back conversion gas CO 2Outlet content reaches below 0.6%.Top at tower is provided with solution inlet port for first section above the filler, a slotted disc type vapour-liquid distributor is set below the solution inlet port.
Adopt wall stream liquid distributor and this slotted disc type gas-liquid distributor to be complementary, the liquid-collecting bottom ring 2 of wall stream liquid distributor is apart from slotted disc type gas-liquid distributor bracing ring 1500mm.The width 300mm of liquid-collecting bottom ring 2 also welds mutually with the tower wall, and liquid-collecting inner tube 1 height 550mm welds mutually with liquid-collecting bottom ring, liquid-collecting inner tube 1, liquid-collecting bottom ring 2 and tower wall 6 common formation fluid storage spaces.Solution feed tube 3 diameter 450mm have the liquid distributing hole of 588 Φ 20mm on liquid-collecting bottom ring 2, liquid by this orifice flow to draining plate 4.Draining plate 4 is welded on the liquid-collecting bottom ring 2, and forms 30 degree angles with it and tilt towards tower wall 6.The liquid that flows down from draining plate flows to the slotted disc type liquid distribution trough on the erosion control ring flat-plate 5 and below the tower wall flows to.
Because being Yan Tabi, liquid flows in the following slotted disc type gas-liquid distributor 8, because surface tension of liquid and the coarse drag effect of tower wall, the liquid that descends is not freely falling body, so its speed that enters liquid distribution trough lowers greatly, the 30%-60% (relevant) that generally has only the freely falling body flow velocity with the roughness of erosion control ring flat-plate or tower wall, therefore the liquid level to the liquid on the seal pot of slotted disc type gas-liquid distributor 8 can not produce fluctuation, thereby guaranteed from slotted disc type gas-liquid distributor to rise the amount of liquid that the spray apertures jet flow on the air drain frid goes out stable, improved gas-liquid distributor flow quantity precision.
The erosion control ring flat-plate is to have the 400mm height with 12mm thickness and along tower body girth welding one material that has identical material with tower body that enclose, and its effect one is to play the kinetic energy buffering, the 2nd, prevent from the tower wall is caused erosion corrosion,
The result of production operation shows, behind the employing wall stream liquid distributor, makes the liquid stream precision of slotted disc type gas-liquid distributor gas-liquid initial distribution improve, and the vapour-liquid mass effect obviously improves, and absorption efficiency reaches more than 98%, CO 2Outlet content drop to below 0.5, surpassed ministry standard, obtained favorable economic benefit.
