Description

Technical Field

[0001] This utility model relates to the field of liquid distributor technology, and in particular to a tray-type liquid distributor. Background Technology

[0002] When processing edible oils and other fats using a vacuum distillation column, a tray-type liquid distributor is typically required to ensure uniform distribution of the edible oil and other substances on the top of the packing material, thus ensuring efficient gas-liquid mass transfer. Existing tray-type liquid distributors typically allow edible oil and other substances to flow directly to the packing material below through the liquid guide channel, while the gas phase rises directly through the distribution channel. This can lead to the following problems: 1. Limited uniform distribution of edible oil on the top of the packing material, mainly concentrated in the area corresponding to the guide channel. Edible oil cannot be effectively distributed on the top of the packing material between adjacent guide channels; 2. Contact between the gas phase and edible oil can easily carry mist and droplets, hindering liquid phase recovery. Utility Model Content

[0003] This invention proposes a tray-type liquid distributor, which, through the cooperation of an arc-shaped plate and a guide groove, facilitates the uniform distribution of edible oil on the top of the packing material; at the same time, the arc-shaped plate intercepts mist and droplets carried by the gas phase, and the intercepted mist and droplets are directly returned to the packing material.

[0004] The technical solution of this utility model is implemented as follows: a tray-type liquid distributor includes a distribution tray with distribution grooves arranged on it. A liquid collection plate is fixed to the upper end of the distribution grooves by a support plate. Liquid guiding grooves are fixed at intervals on the inner wall of the distribution grooves. Overflow holes are provided on the distribution grooves corresponding to the liquid guiding grooves. Arc-shaped plates are provided on both sides below the distribution grooves. The openings of the arc-shaped plates face downwards. The tops of the arc-shaped plates correspond to the outlets of the liquid guiding grooves. Both sides of the arc-shaped plates are serrated edges, and the serrated edges of adjacent arc-shaped plates are spaced apart.

[0005] Furthermore, an L-shaped support rod is welded and fixed to the upper end of the arc-shaped plate, and a first connecting plate is fixed to the lower end of the distribution groove. The L-shaped support rod and the first connecting plate are connected by bolts.

[0006] Furthermore, the liquid collection plate is a V-shaped plate with the opening facing upwards, and the upper edge of the V-shaped plate is provided with a downward-facing bent edge.

[0007] Furthermore, a second connecting plate is fixed to the upper end of the distribution groove, and the support plate is connected to the second connecting plate by bolts. The positions of the second connecting plate and the first connecting plate are set accordingly.

[0008] Furthermore, the distribution groove corresponding to the liquid guiding groove is provided with multiple overflow holes, which are arranged at vertical intervals.

[0009] Furthermore, tear ducts are provided circumferentially along the edge of the distribution disc.

[0010] The beneficial effects of this utility model are: This invention utilizes an arc-shaped plate. Edible oil flows down through a guide channel to the arc-shaped plate, and then is split to both sides by the arc-shaped plate, which facilitates the even distribution of edible oil on the top of the packing. When the gas phase rises through the packing, it is intercepted by the arc-shaped plate, and then the gas phase passes through the adjacent serrated edge and enters the distribution channel. The intercepted mist and droplets are directly returned to the packing. Attached Figure Description

[0011] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] Distribution plate 1, tear hole 2, distribution groove 3, liquid collection plate 4, second connecting plate 5, bent edge 6, liquid guiding groove 7, overflow hole 8, arc plate 9, L-shaped support rod 10, first connecting plate 11, serrated edge 12. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-3 As shown, a tray-type liquid distributor includes a distribution tray 1. Tear holes 2 are circumferentially arranged along the edge of the distribution tray 1 to drain accumulated liquid. Distribution channels 3 are arranged on the distribution tray 1. A collection plate 4 is fixed to the upper end of the distribution channels 3 via a support plate. Specifically, a second connecting plate 5 is fixed to the upper end of the distribution channels 3, and the support plate is bolted to the second connecting plate 5. The support plate is welded to the lower side of the collection plate 4. The collection plate 4 is an upward-opening V-shaped plate with a downward-facing bent edge 6 at the upper edge to ensure that liquid falls onto the distribution tray 1 via the collection channels, rather than sliding down the lower surface of the collection plate 4.

[0016] Liquid guiding channels 7 are fixedly fixed at intervals on the inner wall of the distribution channel 3. Multiple overflow holes 8 are provided on the distribution channel 3 corresponding to the liquid guiding channels 7, such as three overflow holes 8 for each liquid guiding channel 7. The three overflow holes 8 are arranged at intervals along the vertical direction. Arc-shaped plates 9 are provided on both sides below the distribution channel 3. L-shaped support rods 10 are welded and fixed to the upper end of the arc-shaped plates 9. A first connecting plate 11 is fixed to the lower end of the distribution channel 3. The L-shaped support rods 10 and the first connecting plate 11 are connected by bolts. The positions of the first connecting plate 11 and the second connecting plate 5 are set accordingly.

[0017] The opening of the arc plate 9 faces downward, and the top of the arc plate 9 corresponds to the middle of the outlet of the liquid guide groove 7. Both sides of the arc plate 9 are serrated edges 12, and the serrated edges 12 of adjacent arc plates 9 are spaced apart.

[0018] The method of using the tray-type liquid distributor is as follows: Liquid grease falls onto the collection plate 4, overflows onto the distribution plate 1, and then flows into the guide trough 7 through the overflow hole 8. It then flows down to the top of the arc plate 9, and then splits to both sides from the top of the arc plate 9, flowing evenly into the packing through the serrated edge 12. The gas phase rises and is intercepted at the arc plate 9, returning to the packing. The gas phase continues to rise through the gap between the adjacent serrated edges 12.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
