Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, specifically relating to a suspended distributor support structure for a reaction vessel and the reaction vessel itself. Background Technology

[0002] Distributors are key components of process equipment in industries such as petrochemicals. The technology is mature and various equipment types exist, among which disc distributors are the most widely used, such as trough discs, perforated discs, and weir discs. Distributors are mainly used to achieve uniform distribution of liquid materials within reaction vessels, increasing the effective surface area for mass and heat transfer, thereby improving reaction efficiency and ensuring product quality.

[0003] Currently, when installing a distributor inside a reaction vessel, a support ring or several support beams need to be welded to the inner wall of the reaction vessel at the corresponding height, based on the distributor's dimensions and the installation height determined by the process. The distributor is then installed onto the support ring or beams to form a fixed installation. However, this traditional support structure has low strength and is difficult to provide long-term stable support for the distributor.

[0004] Patent CN202432190U discloses a support mechanism for a tray-type distributor, comprising components such as a tray, support frame, support ring, support plate, and support base. While its optimized structure improves structural support strength to some extent, the installation height of the distributor affects the uniformity of liquid distribution within the container, the contact efficiency with reactants, and the reaction time. Therefore, there are often specific requirements for the installation height of the distributor within the reaction vessel. For example, in gas-liquid reactions, if the distributor height is set too high, the liquid atomized may experience excessive falling distance, premature polymerization due to gravity, or insufficient mixing with the gas. If the distributor height is too low, the liquid may not adequately cover the reaction area, leading to incomplete local reactions. Therefore, if adjustments to the reaction process significantly change the required installation height of the distributor, this type of fixed-installation support structure cannot adjust the distributor's installation height, making it difficult to adapt to the adjustment requirements of different process conditions. Furthermore, modifying the structure of the reaction vessel's sidewall to facilitate distributor maintenance, allowing for detachable installation and maintenance (as in CN207153147U), would reduce the structural strength and performance of the reaction vessel itself. This would not only affect reaction efficiency but also pose safety hazards, making it counterproductive. Therefore, there is an urgent need for a suspended distributor support structure and reaction vessel that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a suspended distributor support structure and a reaction vessel, aiming to solve the current problem of being unable to adjust the installation height of the distributor within the reaction vessel according to process requirements, and the difficulty in resolving the inconvenience of distributor maintenance while ensuring the performance of the reaction vessel.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0025] Example 1: See attached Figure 1 The first aspect of this utility model provides a suspended distributor support structure for a reaction vessel.

[0026] A suspended distributor support structure for a reaction vessel includes a support ring assembly 1, a suspension unit, and two flanges 2. The two flanges 2 are arranged opposite each other and horizontally fixed inside the reaction vessel. The support ring assembly 1 is sandwiched between the two flanges 2 and forms a sealed connection with them. The suspension unit includes a support carrier 4 and several suspension rods 3. The support carrier 4 is suspended below the support ring assembly 1 by the several suspension rods 3. The support carrier 4 adjusts its vertical distance relative to the support ring assembly 1 by changing its connection position relative to the suspension rods 3. The support carrier 4 provides fixed support for the distributor 5. As can be seen from the above structure, the flanges 2, as the connection medium between the support ring and the reaction vessel, are the structural foundation ensuring the stable installation of the entire support structure within the reaction vessel. The two flanges 2 are arranged opposite each other and horizontally fixed inside the reaction vessel. Specifically, flange 2 can be fixed to the inside of the reaction vessel shell by welding or other methods, or the reaction vessel shell can be designed in two segments, with two flanges 2 respectively located on the two shell segments. The two flanges 2 are sealed to the support ring assembly 1, achieving a tight connection between the two shell segments. The support ring assembly 1, as the main load-bearing component of the entire structure, provides a stable mounting base for the suspension unit by being sandwiched between the two flanges 2, ensuring connection stability. Simultaneously, by forming a sealed connection with the two flanges 2, it further prevents corrosive substances from the reaction vessel from seeping into the gap between the flanges 2 and the support ring assembly 1, thus ensuring the overall service life of the equipment. The upper and lower ends of the suspension rod 3 connect both the support ring assembly 1 and the support carrier 4. The connection position between the suspension rod 3 and the support ring assembly 1 can be fixed, while the connection between the suspension rod 3 and the support carrier 4 is relatively adjustable. The distributor 5 is fixedly or detachably connected to the support carrier 4 through various existing mechanical connection methods. The support carrier 4 adjusts its vertical distance relative to the support ring assembly 1 by changing its connection position relative to the suspension rod 3, thereby achieving vertical position adjustment of the distributor 5 inside the reaction vessel to meet the process requirements under different reaction conditions.

[0027] Example 2: See attached Figures 1-5Based on Embodiment 1, the support ring assembly 1 includes a support ring 11; a plurality of first lugs 12 are evenly distributed circumferentially on the outer side of the support ring 11; the first lugs 12 extend radially outward and have vertical positioning through holes 121; the flange 2 is provided with a plurality of vertical fixing through holes 21; the fixing through holes 21 and the positioning through holes 121 have the same diameter and correspond one-to-one. From the above structure, it can be seen that the positioning through holes 121 on the first lugs 12 are used to align with the fixing through holes 21 on the flange 2 to avoid misalignment during installation. Then, external connecting bolts pass through both the fixing through holes 21 and the corresponding positioning through holes 121 for fixing, thereby fixing the radial relative position between the flange 2 and the support ring assembly 1.

[0028] It also includes two sealing gaskets; the two sealing gaskets are respectively disposed between the support ring assembly 1 and one of the flanges 2. As can be seen from the above structure, the sealing gaskets have a certain deformation capacity. The two sealing gaskets are respectively disposed on the upper and lower sides of the support ring 11 to fill any small gaps that may exist between the support ring and the flange contact surfaces. When the two flanges 2 clamp the support ring assembly 1, the sealing gaskets deform to fill the gaps in the contact surfaces, thereby achieving a sealed connection between the support ring assembly 1 and the two flanges 2.

[0029] Example 3: See attached Figures 1-5 Based on Embodiment 2, there are two specific implementation methods for mounting the suspension rod 3 on the support ring assembly 1: Implementation Method 1: The inner side of the support ring 11 is provided with a plurality of second lugs 13; the second lugs 13 are evenly distributed around the circumference of the support ring 11 and extend radially inward; the second lugs 13 have suspension through holes; the suspension rods 3 correspond one-to-one with the suspension through holes and are vertically inserted through the suspension through holes onto the second lugs 13; the lower end of the suspension rods 3 is used to connect with the support carrier 4.

[0030] As can be seen from the above structure, for reactions with a small diameter, multiple second lugs 13 can be provided inside the support ring 11 as mounting bases for the suspension rod 3 to be installed on the support ring assembly 1. The second lugs 13 are evenly distributed around the circumference of the support ring 11 and extend radially inward. Preferably, the number of second lugs is four or eight. The suspension rod 3 is vertically inserted through the suspension holes on the second lugs 13, and the lower end of the suspension rod 3 is connected to the support carrier 4, thereby stably suspending the support carrier 4 below the support ring 11, indirectly realizing the function of suspending the distributor 5 inside the reaction vessel.

[0031] Implementation Method Two: A reinforcing plate 14 is provided on the inner side of the support ring 11. Several vertically arranged suspension holes are provided on the reinforcing plate 14. These suspension holes are evenly distributed on the reinforcing plate 14, and the spacing between adjacent suspension holes is equal. The suspension rod 3 is vertically inserted through the suspension holes onto the reinforcing plate 14. The lower end of the suspension rod 3 is used to connect to the support carrier 4. As can be seen from the above structure, for a large diameter reaction vessel, the upper end of the suspension rod 3 requires stronger support. Therefore, a reinforcing plate 14 is provided on the inner side of the support ring 11 to improve the overall structural strength of the support ring assembly 1. The suspension rod 3 is vertically inserted through the suspension holes on the reinforcing plate 14, and the lower end of the suspension rod 3 is connected to the support carrier 4. By suspending the support carrier 4 below the support ring 11, the function of suspending the distributor 5 inside the reaction vessel is indirectly achieved.

[0032] The reinforcing plate 14 is in the shape of a cross, a grid, or a star. As can be seen from the above structure, by setting the reinforcing plate 14 in a cross, grid, or star shape, the connection strength between it and the inner side of the support ring 11 can be enhanced. Furthermore, the cross, grid, or star shape distribution allows the reinforcing plate 14 to effectively distribute the load from the suspension rod 3 and the support carrier 4, and to more evenly transfer the load to the support ring 11, ensuring the stability of the support.

[0033] Example 4: See attached Figures 1-6Based on Embodiment 3, the supporting carrier 4 is a supporting cylinder; several fixing members 41 are connected to the inner side of the supporting cylinder; the fixing members 41 are used to fix to the lower end of the suspension rod 3. As can be seen from the above structure, the supporting carrier 4 is a supporting cylinder, and the outer diameter of the supporting cylinder can be set slightly smaller than the inner diameter of the reaction vessel. On the one hand, this allows it to slide up and down relative to the reaction vessel for modular assembly and disassembly; on the other hand, if the diameter of the supporting cylinder is too small, it will affect the coverage range of the liquid output by the distributor 5. Therefore, setting the outer diameter of the supporting cylinder slightly smaller than the inner diameter of the reaction vessel also provides a relatively wide installation space for the distributor 5, allowing the liquid output by the distributor 5 to fully cover the reaction vessel. Several fixing members 41 are connected to the inner side of the supporting cylinder, and the structure of the fixing members 41 can be adaptively adjusted according to the specific structure of the supporting ring assembly 1. When the inner side of the support ring 11 is connected to the second lug 13, the fixing member 41 can be set as multiple fixing platforms connected to the inner wall of the support cylinder, and the fixing platforms correspond one-to-one with the second lug 13, so that the suspension rod 3 passes through the second lug 13 and the corresponding fixing platform in the vertical direction at the same time and is fixed at both ends, so as to complete the connection between the support ring assembly 1 and the support carrier 4; if the support ring assembly 1 adopts the reinforcing plate 14, the fixing member 41 can also be set as a fixing plate with the same shape as the reinforcing plate, so that the suspension rod 3 passes through the reinforcing plate 14 and the fixing plate in the vertical direction at the same time and is fixed at both ends, thus completing the connection between the support ring assembly 1 and the support carrier 4. Through such an adaptation design, it is ensured that the fixing member 41 can form a stable fit with the support ring assembly 1 with different structures, ensuring the reliability of the suspension rod 3 connection.

[0034] The suspension rod 3 includes a threaded rod 31, two nuts 32 and two washers 33; the two nuts 32 are respectively sleeved on the upper and lower sides of the threaded rod 31 and are threadedly engaged with the threaded rod 31; the two washers 33 are both sleeved on the threaded rod 31 and are located inside the two nuts 32. As can be seen from the above structure, the suspension rod 3 is fixed to the support ring assembly 1 and the support carrier 4 through a threaded rod 31, two nuts 32, and two washers 33. The upper part of the threaded rod 31 vertically passes through the second lug 13 or reinforcing plate 14 of the support ring assembly 1. One nut 32 and one washer 33 are located above the second lug 13 or reinforcing plate 14. When the support ring 11 is fixed by the two flanges 2, the nut 32 is screwed downwards to a preset position, and the washer 33 abuts against the second lug 13 or reinforcing plate 14, completing the installation of the upper part of the threaded rod 31. Simultaneously, the lower part of the threaded rod 31 vertically passes through the fixing member 41, and another nut 32 and another washer 33 are located below the fixing member 41. The nut 32 can be screwed upwards to a preset position, and the corresponding washer 33 abuts against the fixing member 41, completing the suspended installation of the support carrier 4. To disassemble, the two nuts 32 are operated in the reverse direction. Furthermore, when adapting to the different reaction vessel requirements for the installation height of the distributor 5, the model of the threaded rod 31 can be changed to ensure that the length of the threaded rod 31 meets the installation requirements. Then, by changing the vertical distance between the nut 32 at the lower end of the threaded rod 31 and the threaded rod 31, the installation position of the support carrier 4 relative to the threaded rod 31 can be adjusted, thereby meeting the adjustment requirements for the installation height of the distributor 5. The operation is simple. Moreover, when installing the support carrier 4, the relative position of the nut 32 at the lower end of the threaded rod 31 and the suspension rod 3 can be used to fine-tune different areas of the distributor 5, improving the flatness of the distributor 5 after installation, so that the distributor 5 can be connected relatively horizontally in the reaction vessel, further improving the installation quality.

[0035] The number of the first lugs 12 is four or an integer multiple of four. As can be seen from the above structure, the number of the first lugs 12 can be adaptively set according to requirements, and can be set to four or an integer multiple of four to ensure the connection effect between the flange 2 and the support ring assembly 1 and improve the connection stability.

[0036] Example 5: See attached Figures 1-6The second aspect of this utility model also provides a reaction vessel, which adopts the suspended distributor support structure described in any of the embodiments one to four, including a first shell 6 and a second shell 7 located directly below the first shell 6; two flanges 2 are respectively horizontally fixed to the bottom of the first shell 6 and the top of the second shell 7; the two flanges 2 are connected to each other by a support ring assembly 1 to form a sealed connection, thereby achieving a sealed connection between the first shell 6 and the second shell 7. As can be seen from the above structure, this utility model adopts a split-type reaction vessel structure, including a first shell 6 and a second shell 7 located directly below the first shell 6. Then, through the sealed connection between the two flanges 2 and the support ring assembly 1, the distributor 5 is suspended, and a reliable sealed connection between the first shell 6 and the second shell 7 is simultaneously achieved. Since this utility model does not require modification of the sidewalls of the reaction vessel and will not cause damage to the performance of the reaction vessel, it can ensure the sealing performance and usability of the reaction vessel during the reaction process, and can better meet the requirements for adjusting pressure, temperature, and other operating conditions during the reaction process.

[0037] Furthermore, when it is necessary to inspect and repair the distributor 5 and its supporting structure, the sealing connection between the support ring assembly 1 and the two flanges 2 can be released, and then the support ring assembly 1 and the suspension unit connected to it can be lifted to the outside as a whole. This allows for quick inspection and repair of the distributor 5 in the suspension unit. After the inspection and repair are completed, the entire assembly can be lifted back into the reaction vessel for reinstallation. In other words, this utility model can realize the modular disassembly and assembly of the supporting structure without disassembling each component and then moving it outward, which can significantly shorten the maintenance time and ensure production efficiency.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
