Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, and in particular to a distillation column tray. Background Technology

[0002] A distillation column is a tower-type gas-liquid contact device used for distillation. The tray is the core component within the distillation column, facilitating heat and mass exchange between the gas and liquid phases. It consists of gas-liquid contact elements (float valves, bubble caps, sieves, etc.), a receiving tray, an overflow weir, a downcomer, and supporting fasteners. Its working principle involves a liquid layer forming on the tray surface, with gas passing through the contact elements and dispersing into bubbles, completing the mass and heat transfer process within the liquid layer.

[0003] When using a distillation column for distillation, the liquid often contains a relatively large number of impurities. During distillation, these impurities can easily clog the micropores on the column tray, affecting gas-liquid permeation, reducing the distillation efficiency of the unit, and impacting the continued use of subsequent units.

[0004] Therefore, it is necessary to provide a new distillation column tray to solve the above-mentioned technical problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 The present invention provides a distillation column tray, which includes: a mounting ring 1, a liquid guide plate 2 fixedly installed inside the mounting ring 1, and a cleaning component 3 provided below the liquid guide plate 2 inside the mounting ring 1.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 4 The liquid guide plate 2 has a boss structure. Multiple evenly distributed guide holes 21 are opened on the outer side of the liquid guide plate 2. Several evenly distributed guide holes 22 are opened in the center of the liquid guide plate 2. The cleaning component 3 includes a support frame 31. The support frame 31 is movably mounted under the liquid guide plate 2 inside the mounting ring 1. Multiple cleaning pins 32 are installed on the top of the support frame 31 through a threaded structure. The position of the cleaning pins 32 is opposite to the position of each guide hole 22.

[0027] It should be noted that since the cleaning pin 32 is connected to the support frame 31 through a threaded structure, the number of cleaning pins 32 can be controlled as needed before use. This avoids the phenomenon that when the blocking block 24 blocks part of the guide hole 21, it will block the movement trajectory of the corresponding cleaning pin 32 below, causing the cleaning assembly 3 to be unable to be lifted as a whole. This allows the cleaning assembly 3 to be lifted and cleaned stably under the drive of the drive assembly 4 in the later stage.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 4The bottom of the mounting ring 1 is provided with a drive assembly 4 for driving the cleaning assembly 3. The drive assembly 4 includes a support ring 41, which is fixedly connected to the bottom of the mounting ring 1. Multiple evenly distributed mounting frames 42 are fixedly installed at the bottom of the support ring 41. A water wheel 43 is rotatably connected inside the mounting frame 42. A cam 431 is fixedly connected to the outer wall of the water wheel 43. The cam 431 has an elliptical structure. A guide frame 44 is fitted on the outer wall of the cam 431 and abuts against it. The top of the guide frame 44 is fixedly connected to the bottom of the support frame 31. A guide rod 441 is fixedly connected to the outer wall of the guide frame 44. The end of the guide rod 441 away from the guide frame 44 is inserted into the mounting frame 42 and abuts against and slides against the inside of the mounting frame 42. A drainage pipe 5 is provided above the water wheel 43 and at the opposite part. The top of the drainage pipe 5 is fixedly connected to the bottom of the liquid guide plate 2, and the inside of the drainage pipe 5 communicates with the inside of the drainage hole 21.

[0029] It should be noted that, through the setting of the drive component 4, when the liquid flowing on the liquid guide plate 2 flows down from the drainage pipe 5 to the water wheel 43 to drive the water wheel 43 to rotate, the elliptical cam 431 can be driven to rotate synchronously. Thus, the top cleaning component 3 can be moved by the abutting between the cam 431 and the guide frame 44, thereby enabling the cleaning component 3 to be lifted and cleaned smoothly without the need for additional driving force.

[0030] Meanwhile, through the sliding connection between the guide rod 441 and the mounting frame 42, the guide rod 441 can provide horizontal support for the top cleaning component 3 during use, thereby reducing the horizontal displacement of the cleaning component 3 and preventing the cleaning pin 32 from deviating from its position.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 4 Below the liquid guiding hole 22 at the bottom of the liquid guiding plate 2, there is a fixedly connected adapter pipe 221. The outer wall of the adapter pipe 221 is provided with several guide pipes 23 and sealing blocks 24 through a threaded structure. The top of the sealing block 24 is at the same level as the top of the liquid guiding plate 2. The bottom end of the guide pipe 23 is provided with a fixedly connected filter screen. The center of the filter screen is provided with a through hole 231. The guide pipe 23 has a variety of different hole diameters.

[0032] It should be noted that: by setting the sealing block 24, when the sealing block 24 is screwed into the adapter block, the interior of the corresponding liquid guiding hole 22 can be sealed, thereby changing the number of holes used for gas-liquid flow. At the same time, by setting various models of guide tubes 23, the corresponding model of guide tube 23 can be selected for installation as needed to change the orifice size of the holes used for gas-liquid flow.

[0033] By installing a filter screen at the bottom of the guide pipe 23, impurities in the flowing liquid can be filtered out during use, which makes it easier for staff to centrally process the impurities later.

[0034] The working principle of the distillation column tray provided by this utility model is as follows:

[0035] When using this device, the operator can first take out the corresponding model and quantity of guide tubes 23 and sealing blocks 24 according to the needs of distillation, and screw the guide tubes 23 and sealing blocks 24 onto the outer wall of the corresponding position of the transfer tube 221 as needed. This allows control over the number of liquid guide holes 22 used for gas-liquid flow and the size of their internal holes, thereby controlling the flow of gas and liquid during subsequent distillation.

[0036] Once the installation is complete, when the liquid falls onto the liquid guide plate 2 inside the installation ring 1, the liquid can flow downward through the through guide hole 21 and guide hole 22. During this process, the liquid flowing out from the guide hole 21 will fall smoothly into the water wheel 43 below through the drainage pipe 5, thereby driving the water wheel 43 to rotate. At this time, the rotating water wheel 43 will drive the cam 431 on the outer wall to rotate synchronously.

[0037] Since the cam 431 has an elliptical structure, the rotating cam 431 can drive the support frame 31 in the cleaning assembly 3 to move synchronously by squeezing against the inner wall of the guide frame 44. Thus, the cleaning pin 32 at the top can be moved by the support frame 31. When the cleaning pin 32 is inserted into the through hole 231 inside the guide tube 23, the impurities filtered inside the guide tube 23 can be lifted and cleaned, thereby reducing the accumulation of impurities inside the guide tube 23, which would cause blockage of the guide tube 23 and affect the flow of gas and liquid.

[0038] Meanwhile, since the bottom of the flow guide tube 23 is a filter screen structure, impurities carried in the liquid can be filtered during the liquid flow process, which makes it easier for staff to clean the impurities in a concentrated manner later.

[0039] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
