Description

Technical Field

[0001] This utility model relates to the field of demister technology, and in particular to a composite demister for petrochemical applications. Background Technology

[0002] A demister is a device used in evaporation processes to prevent steam from carrying away useful products or contaminating the condensate. Existing demisters mainly consist of a frame and a filament layer, and are typically installed inside a distillation column. When gas mixed with mist rises at a certain speed through the filament layer, the mist collides with the filaments and adheres to their surface. Due to gravity, the mist settles, forming larger droplets that flow along the filaments to the junction of two filaments. The wettability of the filaments, the surface tension of the liquid, and the capillary action of the filaments cause the droplets to grow larger and larger until the accumulated droplets become so large that their own weight exceeds the combined force of the gas's upward force and the liquid's surface tension. At this point, the droplets separate from the filaments and fall, achieving the demisting effect.

[0003] Existing demisters cannot adjust their speed, and excessively high gas flow rates are also detrimental to their normal operation. High-speed airflow may cause the wire mesh to vibrate, damaging its stability and affecting the demistering effect. The inability to adjust the gas speed may also make the demister more prone to clogging and vibration, which increases the difficulty and frequency of equipment maintenance. Therefore, there is a need to provide a demister with adjustable speed to improve its applicability. Utility Model Content

[0004] The purpose of this utility model is to provide a composite demister for petrochemical applications, in order to solve the problems mentioned in the background art, such as the inability to adjust the speed of existing demisters, the fact that excessively high gas flow rates are also detrimental to the normal operation of demisters, the possibility that high-speed airflow may cause the wire mesh to vibrate, thereby damaging the stability of the wire mesh and affecting the demister effect, and the inability to adjust the gas speed may make the demister more prone to problems such as blockage and vibration, which increases the difficulty and frequency of equipment maintenance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a composite demister for petrochemical applications, comprising:

[0007] A defogging assembly, comprising a wire mesh and an upper pressure ring, wherein the upper pressure ring is fixed to the top surface of the wire mesh;

[0008] The adjustment assembly includes a fixed plate, a rotating groove, a first circular hole, a rotating plate, and a second circular hole. The fixed plate is fixed to the lower end of the inner part of the upper pressure ring. The rotating groove is opened in the center of the fixed plate. The first circular hole is opened on the surface of the fixed plate. The rotating plate is rotatably installed inside the rotating groove. The second circular hole is opened on the surface of the rotating plate.

[0009] Furthermore, the defoaming assembly also includes a connecting rod and a lower pressure ring. The connecting rod is laterally fixed inside the upper pressure ring, and the lower pressure ring is located on the bottom surface of the wire mesh.

[0010] Furthermore, a crossbeam is fixed in the middle of the connecting rod, and both ends of the crossbeam are fixed to the inner wall of the upper pressure ring.

[0011] Furthermore, a circular groove is provided at the center of the top surface of the crossbeam, and the circular groove penetrates the crossbeam and communicates with the rotating groove.

[0012] Furthermore, a rotating handle is rotatably inserted inside the circular groove, and the bottom surface of the rotating handle is fixedly connected to the center of the upper surface of the rotating plate.

[0013] Furthermore, it also includes a disassembly and assembly assembly, which includes a through hole and a through post. The through hole is opened on the outer surface of the upper pressure ring and the lower pressure ring, and the through post passes through the through hole and passes through the wire mesh.

[0014] Furthermore, threaded grooves are provided at both the upper and lower ends of the through column, and fixing nuts are threaded to both ends of the threaded grooves, with the fixing nuts contacting the upper pressure ring and the lower pressure ring.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, through the setting of a defoaming component and an adjustment component, allows the operator to adjust the gap between the first and second circular holes when dealing with liquids with a relatively fast foaming rate. The operator holds the rotating handle and rotates it, which in turn drives the rotating plate to rotate. The rotation of the rotating plate synchronously drives the second circular hole to rotate, causing the second circular hole to be misaligned with the first circular hole, thus reducing the gap between the first and second circular holes and preventing the generated foam from passing through the wire mesh too quickly. By adjusting the size of the gap, the operator can precisely control the foaming rate of the liquid to adapt to the characteristics and processing needs of different liquids.

[0017] Second, based on the first beneficial effect, by setting up the disassembly and assembly components, when disassembling and assembling the wire mesh, the workers only need to unscrew the fixing nuts from the upper and lower ends of the through post, and then pull the through post out of the through hole. The wire mesh can be disassembled from the upper and lower pressure rings. The disassembly and assembly of the wire mesh can be completed in a simple step without complicated tools or operations, which improves work efficiency. Attached Figure Description

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figures 1 to 4 As shown, this embodiment is a composite demister for petrochemical applications, comprising:

[0032] The defogging assembly includes a wire mesh 11 and an upper pressure ring 12. The upper pressure ring 12 is fixed to the top surface of the wire mesh 11. The defogging assembly also includes a connecting rod 13 and a lower pressure ring 14. The connecting rod 13 is horizontally fixed inside the upper pressure ring 12, and the lower pressure ring 14 is located on the bottom surface of the wire mesh 11.

[0033] The wire mesh 11 is responsible for gas-liquid separation. When gas containing mist passes through the wire mesh 11, due to the inertia of the mist, the mist collides with the fine wires of the wire mesh 11 and adheres to the surface of the fine wires. Subsequently, the mist diffuses on the surface of the fine wires and settles due to gravity, forming larger droplets. Finally, the droplets flow along the fine wires to the junction point and separate and fall. The upper pressure ring 12 plays a role in stabilizing and pressing the wire mesh 11 to ensure that the wire mesh 11 will not shift or deform during operation. The lower pressure ring 14 is similar to the upper pressure ring 12 and also plays a role in stabilizing and pressing the wire mesh 11.

[0034] The adjustment assembly includes a fixed plate 22, a rotating groove 23, a first circular hole 25, a rotating plate 27, and a second circular hole 28. The fixed plate 22 is fixed inside the lower end of the upper pressure ring 12. The rotating groove 23 is opened in the center of the fixed plate 22. The first circular hole 25 is opened on the surface of the fixed plate 22. The rotating plate 27 is rotatably installed inside the rotating groove 23. The second circular hole 28 is opened on the surface of the rotating plate 27.

[0035] The rotating plate 27 is one of the core components of the adjustment assembly. By rotating the rotating handle 26, the rotating plate 27 can be driven to rotate synchronously, thereby changing the relative position between the first circular hole 25 and the second circular hole 28. The rotating groove 23 is used to accommodate and guide the rotation of the rotating plate 27, providing a stable rotation axis for the rotating plate 27 and ensuring that the rotating plate 27 can remain stable and accurate during rotation.

[0036] A crossbeam 21 is fixed in the middle of the connecting rod 13, and both ends of the crossbeam 21 are fixed to the inner wall of the upper pressure ring 12. A circular groove 24 is opened in the center of the top surface of the crossbeam 21, and the circular groove 24 passes through the crossbeam 21 and communicates with the rotating groove 23. A rotating handle 26 is rotatably passed through the inside of the circular groove 24, and the bottom surface of the rotating handle 26 is fixedly connected to the center of the upper surface of the rotating plate 27.

[0037] The rotating handle 26 is a tool used by the operator to control the rotation of the rotating plate 27. By holding the rotating handle 26 and turning it, the rotating plate 27 can be easily driven to rotate synchronously, thereby adjusting the size of the aperture.

[0038] Working principle:

[0039] For liquids with a fast foaming rate, the operator can adjust the gap between the first circular hole 25 and the second circular hole 28. The operator holds the rotating handle 26 and rotates the rotating handle 26. The rotating handle 26 drives the rotating plate 27 to rotate. The rotation of the rotating plate 27 drives the second circular hole 28 to rotate simultaneously, so that the second circular hole 28 is misaligned with the first circular hole 25, and the gap between the first circular hole 25 and the second circular hole 28 is reduced, so as to prevent the generated foam from passing through the wire mesh 11 quickly.

[0040] This step allows staff to precisely control the rate of liquid foaming by adjusting the size of the pores, adapting to the characteristics of different liquids and processing needs.

[0041] Please see Figures 1 to 4 As shown; this embodiment, based on embodiment 1 above, further includes:

[0042] The disassembly and assembly assembly includes a through hole 31 and a through post 32. The through hole 31 is opened on the outer surface of the upper pressure ring 12 and the lower pressure ring 14. The through post 32 passes through the inside of the through hole 31 and passes through the wire mesh 11. The upper and lower ends of the through post 32 are provided with threaded grooves 33, and the two ends of the threaded grooves 33 are threadedly connected to fixing nuts 34. The fixing nuts 34 are in contact with the upper pressure ring 12 and the lower pressure ring 14.

[0043] The through hole 31 ensures that the through post 32 can accurately pass through the upper pressure ring 12 and the lower pressure ring 14, thereby providing stable support for the wire mesh 11. The fixing nut 34 contacts the upper pressure ring 12 and the lower pressure ring 14. By rotating the fixing nut 34, the position of the through post 32 in the through hole 31 can be adjusted, thereby changing the tension of the wire mesh 11 or disassembling it.

[0044] Working principle:

[0045] When disassembling and assembling the wire mesh 11, the staff only needs to unscrew the fixing nut 34 from the upper and lower ends of the through post 32, and then pull the through post 32 out of the through hole 31. The wire mesh 11 can be disassembled from the upper pressure ring 12 and the lower pressure ring 14. The disassembly and assembly of the wire mesh 11 can be completed through simple steps.

[0046] This step requires no complicated tools or operations, thus improving work efficiency.
