TW529968B - Liquid distributor in mass transfer column and method of installation and use - Google Patents

Abstract

A mass transfer column is provided with a liquid distributor that distributes liquid to an underlying mass transfer bed containing one or more random, grid or structured packing elements. The liquid distributor includes a plurality of elongated troughs that are spaced apart and extend across the column. A plurality of liquid discharge holes are positioned in side walls of the trough and are located in one or more preselected planes that are preferably spaced above a floor of the trough. Splash baffles are spaced outwardly from the trough side walls and include upper portions that are positioned to receive liquid exiting the troughs through the discharge holes. Lower portions of the splash baffles form a constricted discharge outlet in a plane below the trough for delivering liquid from the splash baffles to the underlying mass transfer bed. The liquid discharge holes in one of the trough side walls are offset from those in the other trough side wall to provide a more uniform distribution of liquid to the discharge outlet. The splash baffles are vertically adjustable and are intended to be supported on the upper surface of the mass transfer bed so that the discharged liquid is delivered directly to the mass transfer bed, thereby reducing the opportunity for the falling liquid to become entrained in a vapor stream flowing upwardly through the mass transfer bed. The liquid exiting through the discharge outlet preferably forms a curtain-like flow that block or impedes vapor entry upwardly into the discharge outlet. Any vapor that enters the discharge area is able to vent upwardly through the open spacing between the baffles and the associated troughs at a reduced velocity, thereby reducing the opportunity for liquid entrainment. The open spacing also permits any overflow of liquid from the troughs to be captured by the splash baffles for downward flow along the inner faces of the splash baffles.

Description

529968 V. Description of the invention (1) Background of the invention The present invention relates to mass transfer towers, and particularly to liquid distributors used in such transfer towers, and a method for distributing liquids using such liquid distributors. When the liquid is not distributed uniformly, the contact between the rising steam flow and the falling liquid flow in the packing section of the mass transfer tower and the consequence of poor mass transfer will result. Generally, these transfer towers use grooved liquid distributors to hold the liquid flowing down from the upper area, and then redistribute it to the lower packed bed in a more uniform manner. The top and bottom of these liquid dispensers can be exposed to reduce the space between the bottom side walls so that when the liquid flows out of the dispenser, it becomes a curtain-like or sheet-like flowing liquid. The liquid fed from the drip tube liquid dispenser will spread over the structured packing surface and will flow down along the wave ripples extending in one direction only. The lower layer of the filler is rotated by 90 degrees to spread the liquid toward the other side, thereby achieving the effect of wetting the entire surface of the filler. In another type of dispenser, such as disclosed in U.S. Patent No. 4,8,1,619, issued to Berve η et al., The bottom of the dispenser is closed and placed at a predetermined position on the side wall of the dispenser Overflow hole. The liquid coming out of the overflow hole is in contact with a splash-proof baffle, which is arranged to maintain a partition system with the side wall of the distributor. Then, the liquid flows down from the money-proof stretcher and drips into the packed bed along a drip line from the drip edge below, so that only one layer of structured packing is needed to spread the liquid to the whole packing in both directions. One problem encountered with conventional liquid dispensers is that the downward flowing liquid may be entrained by the rising stream. In the liquid distributor disclosed in U.S. Patent No. 4,8 丨 6,19, 丨, when steam flows upward into the splash guard and

529968 V. Description of the invention (2) The side wall of the distributor is evenly divided when the inner surface rises. When the flanges are closed, this convex invention is an overview of the invention, the transfer bed. The liquid mass transfer bed is provided with one or more, but preferably elongated grooves. The first and the upper are connected between the grooves, but entrainment may be caused when the space between the first and the upper is included. In addition, the liquid is between the two splash guards, thus providing the opportunity for steam to be entrained along the splash guards. In other liquid dispensers, as shown in the Patent No. 0282753B1, when the liquid plate is discharged downward along the money-proof stretcher, a liquid-proof second plate is used to block the liquid. Because the lower edge of the splash guard is separated from the upper surface of the transfer bed, when the space between the liquid: edge and the surface of the mass transfer bed flows downward: the risk of liquid. In addition, the upper part of the 'spatter-proof stretcher' and the dispenser space are connected by a splash-proof baffle to the side wall of the dispenser. When the steam flows into the space between the splash guard and the second plate, the steam can be prevented from escaping upward. The allocation of one of the moving towers is based on the above. The second aspect of the space is to provide a device for use in the space, which is used to raise the selected feed shaft to the bottom and to equalize each other. Each groove is provided with a side wall. Several splash-proof baffles in offset style are opened to lower the steam flow box to keep flat space and separate liquids are arranged on the two sides. The internal empty liquid flow in the mass will interact with each other to make the liquid flow relationship. The liquid compartment of the steam and the lower transfer tower with an upper plate on the side wall is placed with a mass to distribute it evenly throughout. The liquid distributor body is conveyed to at least one extended traverse transfer tower and can flow up into the adjacent bottom plate so that they are connected to each other on at least the first side wall. The other part of the liquid dispenser is

Page 9 529968 V. Description of the invention (3) A reduced discharge hole is formed on the plane below the groove. At least the upper section of the first base bumper plate is spaced outward from the first side wall and extends a sufficient distance upward relative to the liquid discharge hole system, so that the liquid flowing out of the liquid discharge hole will be destroyed by the splash guard, and then Flows down the inside of the baffle. The second anti-secondary broadcast board may also be provided with an upper section which is similar or identical to the second side wall of the trench. With respect to the groove, at least the first splash prevention baffle, but preferably both splash prevention baffles can be adjusted longitudinally so as to be able to descend onto the upper surface of the mass transfer bed. " In this way, the liquid is delivered directly from the reduced-emission outlet of the groove to the mass transfer bed, so there is no need to pass through a steam stream that may entrain a portion of the liquid. In one embodiment, the liquid dispenser includes a serrated drip edge from the discharge outlet ^: to deliver at least a portion of the liquid to the bed, rather than just the upper surface. The 2 of the liquid distributor is to reduce the discharge σ, which can block or prevent the steam from passing through the discharge hole, otherwise it will prevent the liquid from flowing downwards. Liquid discharge = ditch = = pattern can make the liquid flow more evenly along the discharge outlet, and the opportunity for Hi vapor to flow into the discharge outlet. Steam such as splash baffle and groove: between: = when the low steam rate flows upwards at the steam outlet, "two; :: ° formed in the space-a lot of steam entrainment machine :: = The liquid flowing down the splash baffle is raised and steamed, but the money is spilled into the ditch;:. The liquid flowing out of the groove through the overflow hole, or the liquid enclosed by the splash-proof baffle f, two, and ^ can all flow into this open space and be transferred downward by the transfer bed along the inner surface of the baffle. Mass structured packings are relatively compact, grille and / or structured packing elements, but on page 10, 529968, invention description (4), another aspect of the present invention is to provide a liquid using the aforementioned liquid distributor. It is distributed to the mass transfer bed to block or block the inflow of steam through the reduced emission outlet formed by the splash barriers. While the liquid is directly transferred to the surface of the negative transfer bed, it also isolates the liquid from the vapor flow, thereby further reducing the chance of liquid being entrained in the vapor flow. This method includes that the steam flowing into the discharge outlet escapes at a relatively low steam rate from the part between the splash guard = the two grooves, so that the situation where the liquid is caught by the splash guard is minimized. . Yet another aspect of the present invention is to provide a method for moving inside a tower, the steps of which are to install a plate so as to be supported / removed or to reduce splash resistance: the lower edge of the strike plate and any gap entrained by the steam flow益 Benefit from the surface of the groove and mass transfer bed. A liquid distributor is installed on the rotating groove, and then the upper surface of the splash-proof mass transfer bed is adjusted downward. Between the mass transfer beds, the adjustable nature of the liquid splash-proof baffle is not parallel. It is very helpful for the drawings to briefly explain the embodiments, and to describe the embodiment of the present invention. The detailed description of the present invention will follow.

Grooves to slow down the peak flow of these movements and the volume distribution of the flow from 66 to ’so that the mass can be directly above the mass transfer bed 18. ^ Opening the drain hole 60 will make each and 66 overlap the grooves of the side wall 50 4 and 56 as shown in Figure 5. The degree of flow difference is due to the location offset from the other location. In this way the combined flow is uniform along the rows. The openings between the top edges of the splash guards 6 4 and 6 6 and the groove side walls 5 4 and 5 6 allow any steam flowing into the discharge site to rise through this opening and contact the liquid flowing downward. Another advantage of this opening is that it enables the liquid flowing out of the groove 50 through the overflow hole 62 to splash onto the splash guards 64 and 66 and then flow down along its inner surface. In another embodiment of the liquid distributor 16 suitable for low liquid flow rate, the drain hole 60 may be provided only on one of the side walls 54 or 56 of the groove. As shown in FIG. 6 ', the liquid of this embodiment is splashed on only one of the splash-proof baffles 64, and then flows downward along the baffle. Because the other splash-proof baffle 6 6 does not contain liquid, it is only used for? The 1 / cheng discharge outlet 72 ′ does not need to be provided outside the trench sidewall 56, but can be used as a vertical or inclined plate located below the trench bottom plate 40. It should also be understood that the structures of the paired splash guards 64 and 66 need not be the same as each other 'as long as a narrow discharge outlet 72 can be formed between the lower edges of the splash guards.
