Description

Technical Field

[0001] This utility model belongs to the field of liquid distribution, and specifically relates to a high-efficiency liquid distribution device. Background Technology

[0002] Distillation columns, whether plate columns or packed columns, all function to separate substances through close contact between the gas and liquid phases. The role of the liquid distribution device is to ensure that the liquid entering the distillation column or the packing layer can cover the entire cross-section, thus laying the foundation for efficient mass and heat transfer processes.

[0003] Traditional liquid distribution devices typically use a single-structure distribution plate. After the liquid enters through a single inlet, it is directly dispersed through the holes on the distribution plate. It is difficult to achieve uniform distribution of the liquid, resulting in large differences in the amount of liquid received by some packing or trays in the distillation column, which affects the distillation efficiency and product purity. Therefore, this application proposes a high-efficiency liquid distribution device to solve the above-mentioned technical problems. Utility Model Content

[0006] Furthermore, the mounting sleeve includes an upper mounting groove formed on the inner side of the mounting sleeve, and the upper liquid distribution plate is disposed on the inner side of the upper mounting groove; The lower mounting slot is formed inside the mounting sleeve and is located below the upper mounting slot.

[0007] Furthermore, the coarse distribution component also includes a number of fixing grooves that are evenly distributed on the upper surface of the upper liquid distribution plate, and the number of fixing grooves are respectively connected to the number of upper liquid distribution holes. The inner side of each of the aforementioned fixing slots has two snap-fit ​​slots symmetrically arranged.

[0008] Furthermore, a number of the flow guiding components are detachably disposed inside a number of the fixing slots.

[0009] Furthermore, the flow guiding component includes a conical sleeve, which is detachably disposed inside the fixing groove; A spiral guide plate is disposed on the inner side of the conical sleeve, and the outer side of the spiral guide plate is in contact with the inner side of the upper liquid distribution hole; The mounting shaft is located on the inner side of the spiral guide plate; An acceleration nozzle is disposed on the lower surface of the spiral guide plate, and the outer side of the acceleration nozzle is in contact with the inner side of the upper liquid distribution hole.

[0010] Furthermore, the conical sleeve is a bottom-opening conical sleeve; Two locking blocks are symmetrically arranged on the lower surface of the conical sleeve, and the two locking blocks are respectively engaged with the inner side of the two locking grooves.

[0011] Furthermore, the fine distribution component includes a lower dispensing plate disposed inside the lower mounting groove; A number of lower distribution holes are evenly distributed on the upper surface of the lower distribution plate.

[0012] Furthermore, a number of conical grooves are evenly distributed on the upper surface of the lower distribution plate, and the number of conical grooves are respectively connected to the inner side of the number of lower distribution holes.

Compared with traditional devices, the uniformity of liquid distribution is greatly improved, effectively improving the distillation efficiency and product purity of the distillation column. At the same time, the flow guiding component adopts a detachable design, allowing operators to easily clean the flow guiding component and the upper liquid distribution hole by pulling out the locking block on the conical sleeve from the locking groove, promptly removing any impurities that may cause blockage and reducing the risk of device clogging.

[0016] 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.

[0017] Please see Figure 1-6 This utility model provides a high-efficiency liquid distribution device, including a mounting sleeve 1; The coarse distribution component 2, located inside the mounting sleeve 1, includes an upper liquid distribution plate 21 located inside the mounting sleeve 1; a number of upper liquid distribution holes 22 evenly distributed on the upper surface of the upper liquid distribution plate 21; and a number of flow guiding components 25 located inside the number of upper liquid distribution holes 22. The fine distribution component 3 is located inside the mounting sleeve 1, and is located below the coarse distribution component 2.

[0018] This embodiment provides a high-efficiency liquid distribution device of the present invention. By setting the mounting sleeve 1 inside the top of the distillation column, the liquid condensed from the condenser in the distillation column will enter the mounting sleeve 1. Then, under the action of the coarse distribution component 2, the liquid can be initially distributed in terms of flow rate and direction, so that the liquid flows evenly to the fine distribution component 3 below. Subsequently, under the action of the fine distribution component 3, the liquid can be evenly sprayed onto each part of the packing or tray in the distillation column.

[0019] Furthermore, such as Figure 3 As shown, in the preferred embodiment of the present invention, the mounting sleeve 1 includes an upper mounting groove 11, which is opened on the inner side of the mounting sleeve 1, and an upper liquid distribution plate 21 is provided on the inner side of the upper mounting groove 11; and a lower mounting groove 12, which is opened on the inner side of the mounting sleeve 1, and is located below the upper mounting groove 11.

[0020] In this embodiment, several preferred embodiments of the mounting sleeve 1 are given. After the mounting sleeve 1 is placed inside the top of the distillation column, the liquid condensed from the condenser in the distillation column will enter the mounting sleeve 1, and then the mounting sleeve 1 can send the liquid into the coarse distribution component 2.

[0021] Furthermore, such as Figure 4 As shown, the coarse distribution component 2 in the preferred embodiment of this utility model further includes a number of fixing grooves 23, which are evenly distributed on the upper surface of the upper liquid distribution plate 21, and the number of fixing grooves 23 are respectively connected to a number of upper liquid distribution holes 22; and two snap-fit ​​grooves 24 are symmetrically opened on the inner side of each of the number of fixing grooves 23.

[0022] More specifically, a number of flow guiding components 25 are detachably disposed on the inside of a number of fixing slots 23.

[0023] Furthermore, such as Figure 5 As shown, the flow guiding assembly 25 includes a conical sleeve 251, which is detachably disposed inside the fixing groove 23; a spiral flow guiding plate 252, disposed inside the conical sleeve 251, with the outer side of the spiral flow guiding plate 252 in contact with the inner side of the upper liquid distribution hole 22; a mounting shaft 253, disposed inside the spiral flow guiding plate 252; and an acceleration nozzle 254, disposed on the lower surface of the spiral flow guiding plate 252, with the outer side of the acceleration nozzle 254 in contact with the inner side of the upper liquid distribution hole 22.

[0024] Furthermore, the conical sleeve 251 is a bottom-opening conical sleeve, so that the liquid inside the mounting sleeve 1 will enter the conical sleeve 251 from the upper liquid distribution plate 21; two locking blocks are symmetrically arranged on the lower surface of the conical sleeve 251, and the two locking blocks are respectively locked into the inner side of the two locking grooves 24.

[0025] This embodiment provides several preferred embodiments of the coarse distribution component 2. The upper distribution plate 21 diverts the liquid within the mounting sleeve 1, allowing the liquid to pass through the conical sleeves 251 of several flow guiding components 25 and enter several upper distribution holes 22. Since the outer side of the spiral guide plate 252 is in contact with the inner side of the upper distribution holes 22, and the mounting shaft 253 is located on the inner side of the spiral guide plate 252, the liquid within the conical sleeve 251 will spiral downwards under the influence of the spiral guide plate 252 and gravity. This causes the liquid to accelerate, and then the accelerated liquid enters the acceleration nozzle 254. Under the action of the acceleration nozzle 254, the rotating and accelerated liquid can be sprayed out, causing the liquid to spread rapidly in all directions and make better contact with the fine distribution component 3, further improving the uniformity of liquid distribution. At the same time, the locking block set on the conical sleeve 251 can be pulled out from the locking groove 24, so that the staff can clean the flow guiding component 25 and the upper liquid distribution hole 22, thereby improving the liquid distribution effect of the coarse distribution component 2.

[0026] Furthermore, such as Figure 6 As shown, the fine distribution component 3 in the preferred embodiment of this utility model includes a lower distribution plate 31 disposed inside the lower mounting groove 12; and a number of lower distribution holes 32 evenly distributed on the upper surface of the lower distribution plate 31.

[0027] Furthermore, a number of conical grooves are evenly distributed on the upper surface of the lower distribution plate 31, and the number of conical grooves are respectively connected to the inner side of a number of lower distribution holes 32; the diameter of the lower distribution hole 32 is smaller than the diameter of the upper distribution hole 22.

[0028] In this embodiment, several preferred embodiments of the fine distribution component 3 are given. Through the lower distribution plate 31, the liquid distributed by the coarse distribution component 2 falls onto the lower distribution plate 31. Subsequently, under the action of the conical groove, the liquid on the lower distribution plate 31 enters the lower distribution hole 32 better. Then, a number of lower distribution holes 32 will evenly spray the liquid onto each part of the packing or tray in the distillation column. In this way, under the action of the coarse distribution component 2 and the fine distribution component 3, the distillation efficiency and product purity of the distillation column can be improved.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
