Abstract

The second wire mesh demister moves upwards along the supporting rod under the impact of the gas, and the reset spring is arranged at the top of the moving frame of the second demister, so that the moving frame is pushed back to the original position by the reset spring when the gas pressure is small, and the gas is discharged out of the second wire mesh demister. According to the enhanced wire mesh demister provided by the utility model, when gas containing entrainment passes through the second wire mesh demister at a certain speed, the second wire mesh demister swings up and down, and substances such as impurities, oil stains, solid particles and the like attached to a wire mesh are vibrated down through vibration generated by the up-down swinging, so that the entrainment is prevented from entering the second wire mesh demister. Therefore, substances such as impurities, greasy dirt and solid particles in the gas are intercepted, the influence of the substances such as the impurities, the greasy dirt and the solid particles in the gas on the first demister which is mainly used for defoaming is reduced, and the defect that the substances such as the impurities, the greasy dirt and the solid particles in the fluid can be attached to the silk screen is overcome.

Description

Technical Field

[0001] This utility model relates to the field of wire mesh demister technology, and in particular to an enhanced wire mesh demister. Background Technology

[0002] According to a wire mesh demister disclosed in Chinese Patent No. CN207591447U, it includes a support ring, a limiting cylinder, a support plate, several guide filaments, and a wire mesh block. The limiting cylinder is vertically fixed to the end face of the support ring, and the support plate is horizontally placed on the support ring inside the limiting cylinder. The diameter of the support plate matches the inner diameter of the limiting cylinder. Several vent holes are evenly distributed on the support plate, and several guide filaments are vertically fixed on the side of the support plate that contacts the support ring. The wire mesh block is placed on the other side of the support plate. Beneficial effects: The above-mentioned wire mesh demister has a simple structure and is easy to implement. It can prevent deformation of the wire mesh block and avoid the phenomenon of the periphery of the wire mesh block falling off the support ring. The use of guide filaments allows the liquid on the wire mesh block and the support plate to collect and drip down along the guide filaments, preventing liquid from adhering to the surface of the wire mesh block and improving the air permeability of the wire mesh block. Replacing and disassembling the wire mesh is convenient and simple, with high replacement efficiency.

[0003] In the gas-liquid separation process, impurities, oil, solid particles, and other substances in the fluid will adhere to the wire mesh in the above-mentioned and existing wire mesh demisters. Over time, these substances will gradually clog the pores of the wire mesh, increasing the resistance when the gas passes through the wire mesh, resulting in poorer gas-liquid separation and reduced demister efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where impurities, oil stains, solid particles, and other substances in the fluid adhere to the wire mesh, and to propose an enhanced wire mesh demister.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an enhanced wire mesh demister, comprising a fixed frame, three first demisters at the bottom of the fixed frame, a metal frame at the top of each of the three first demisters, four support rods at the bottom of the fixed frame, three movable frames at the bottom of the three first demisters, a second demister at the bottom of each of the three movable frames, a return spring at the top of each of the three metal frames, and a connecting rod at the top of each of the three movable frames.

[0006] Preferably, the three metal frames are in a parallel state, and all three metal frames are bolted to the fixing frame.

[0007] Preferably, all three first demisters are aligned with the vertical central axis of the metal frame, and all three first demisters are engaged with the top metal frame.

[0008] Preferably, the four support rods at the bottom of the fixing frame are arranged in a circumferential array, and the top of each of the four support rods passes through the first demister, the metal frame, and the fixing frame. The four reset springs are evenly sleeved with the four support rods.

[0009] Preferably, the three movable frames are positioned perpendicular to the three metal frames, and the three movable frames are fixed together by connecting rods.

[0010] Preferably, all three second demisters are perpendicular to the three movable frames, and all the second demisters are engaged with the movable frames.

[0011] Preferably, the bottom ends of all four support rods pass through the movable frame and the second demister.

[0012] Beneficial effects

[0013] In this invention, when gas containing mist passes through a second wire mesh demister at a certain speed, the second wire mesh demister intercepts impurities, oil, solid particles, and other substances in the gas, causing them to adhere to the wire mesh. The second wire mesh demister moves upward along the support rod under the impact of the gas. Because a return spring is installed at the top of the moving frame of the second demister, when the gas pressure is low, the moving frame is pushed back to its original position by the return spring, thus causing the second demister to swing up and down. The vibration generated by this up-and-down swing shakes off the impurities, oil, solid particles, and other substances adhering to the wire mesh, thereby intercepting impurities, oil, and solid particles in the gas and reducing their impact on the primary demister, which is responsible for demisting. This solves the problem of impurities, oil, and solid particles in the fluid adhering to the wire mesh. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4 An enhanced wire mesh demister includes a fixed frame 1, three first demisters 3 at the bottom of the fixed frame 1, metal frames 2 at the top of each of the three first demisters 3, four support rods 4 at the bottom of the fixed frame 1, three movable frames 6 at the bottom of the three first demisters 3, and second demisters 7 at the bottom of each of the three movable frames 6. Return springs 5 ​​are located at the top of each of the three metal frames 2, and connecting rods 8 are located at the top of each of the three movable frames 6. The three metal frames 2 are parallel to each other and bolted to the fixed frame 1. The three first demisters 3 are aligned with the vertical central axis of each of the metal frames 2. The three first demisters 3 are all snapped into the metal frame 2 at the top. The four support rods 4 at the bottom of the fixed frame 1 are arranged in a circular array, and the top of each of the four support rods 4 passes through the first demisters 3, the metal frame 2 and the fixed frame 1. The four return springs 5 ​​are evenly sleeved with the four support rods 4. The three movable frames 6 are set in a position perpendicular to the three metal frames 2, and the three movable frames 6 are fixed together by connecting rods 8. The three second demisters 7 are all set in a position perpendicular to the three movable frames 6, and the second demisters 7 are snapped into the movable frames 6. The bottom of each of the four support rods 4 passes through the movable frames 6 and the second demisters 7.

[0024] The fixed frame 1 is installed inside the tower body by fixing bolts, serving as the support frame for the entire demister and providing a foundation for the installation and fixation of other components. It bears the weight of the entire demister and the external forces such as pressure generated when gas passes through, ensuring the stable installation and operation of the demister within the equipment. The metal frame 2 primarily supports and fixes the first demister 3. It engages with the first demister 3, ensuring the first demister 3 is stably positioned in its working state and that the gas passes evenly through the first demister 3 for demisting. The metal frame 2 is installed on the fixed frame 1 by fixing bolts. The first demister 3 is the main demisting component. When gas containing mist passes through, it utilizes the structural characteristics of the wire mesh, employing principles such as inertial collision, gravitational settling, and surface tension adsorption to intercept and capture the mist in the gas, achieving gas-liquid separation, removing most of the mist from the gas, and improving the purity and quality of the gas. It is aligned with and engaged with the vertical central axis of the metal frame 2, ensuring that the gas passes evenly through all parts of the first demister 3, fully utilizing its demisting function. The support rod 4 serves as a guide and support. Four support rods 4 are arranged in a circular array at the bottom of the fixed frame 1. Their top ends pass through the first demister 3, the metal frame 2, and the fixed frame 1, while their bottom ends pass through the movable frame 6 and the second demister 7. The support rods 4 provide precise guidance for the vertical movement of the second demister 7, ensuring that the second demister 7 can only move up and down along the support rods 4 under gas impact, without deviation or swaying, thus guaranteeing the stability and reliability of the second demister 7's movement. Simultaneously, the support rods 4 also bear the weight of the second demister 7 and the movable frame 6, as well as the forces generated during movement, ensuring the strength and stability of the entire structure. A return spring 5 is sleeved with the support rods 4. When the second demister 7 moves upward along the support rods 4 under gas impact, the return spring 5 is compressed, storing elastic potential energy. When the gas pressure is low, the return spring 5 releases its elastic potential energy, and the resulting elastic force pushes the movable frame 6 back to its original position. Since the second demister 7 is engaged with the movable frame 6, the second demister 7 completes its vertical swing. This periodic up-and-down oscillation generates vibration, shaking off impurities, oil, solid particles, and other substances adhering to the wire mesh of the second demister 7. This prevents these substances from clogging the wire mesh and affecting the demisting effect, while also reducing the impact of these substances on the first demister 3, which is primarily responsible for demisting, thus extending its service life and maintenance cycle. The movable frame 6 is used to install and fix the second demister 7, and three movable frames 6 are fixed together by connecting rods 8 to form a single movable structure. The movable frame 6 is perpendicular to and interlocked with the second demister 7, ensuring that the second demister 7 can be stably installed on the movable frame 6 and move up and down along the support rod 4 with the movable frame 6. Under the combined action of gas impact and the return spring 5, the movable frame 6 drives the second demister 7 to oscillate up and down, achieving a self-cleaning function for the wire mesh of the second demister 7.The second demister 7 is also a demisting component. Since it is installed at the bottom of the first demister 3, the gas containing mist will first pass through the second demister 7 when it rises. As the gas containing mist passes through at a certain speed, it intercepts impurities, oil, solid particles, and other substances in the gas, causing them to adhere to the wire mesh. The connecting rod 8 connects the three movable frames 6 together, enabling them to move synchronously and ensuring the coordination and consistency of the overall up-and-down swing of the second demister 7. This avoids problems such as inconsistent movement or jamming due to uneven force on a single movable frame 6 or the second demister 7, ensuring the stable operation of the entire self-cleaning system. It is important to note that the bottom and top of the support rod 4 are fixed with nuts to prevent the support rod 4 and the movable frames 6 from falling off. When the second demister 7 is completely blocked, the fixing nut at the bottom of the second demister 7 can be removed, and the movable frames 6 and the second demister 7 on them can be removed for cleaning, maintenance, and replacement. Specific Implementation Example 2:

[0026] Reference Figure 1-4 An enhanced wire mesh demister, further based on the basic structure of Specific Embodiment 1, introduces a gas containing mist. The gas first enters the enhanced wire mesh demister and passes through a second demister 7. As the gas passes through the second demister 7, it intercepts impurities, oil, solid particles, and other substances in the gas, causing them to adhere to the wire mesh, thus completing the initial interception and cleaning of these substances. Simultaneously, due to the impact force of the gas, the second demister 7 moves upward along the support rod 4, at which point the return spring 5 is compressed. When the gas pressure is low, the return spring 5 releases its elastic potential energy, pushing the moving frame 6 and the second demister 7 back to their original position, causing the second demister 7 to swing up and down. The vibration generated by this up-and-down swing dislodges impurities, oil, solid particles, and other substances adhering to the wire mesh of the second demister 7, thereby reducing their impact on the subsequent primary demister 3, which is responsible for demisting.

[0027] After preliminary treatment by the second demister 7, the gas continues to flow upward and passes through the first demister 3. The first demister 3 utilizes a wire mesh structure and employs principles such as inertial collision, gravity settling, and surface tension adsorption to more precisely intercept and capture the mist in the gas, achieving gas-liquid separation and further improving the purity and quality of the gas, ensuring that the gas after passing through the demister meets the requirements of subsequent processes or equipment.

[0028] Throughout the process, the fixed frame 1 provides stable support, the metal frame 2 fixes the first demister 3 and installs it on the fixed frame 1, the support rod 4 ensures the movement guidance and support of the second demister 7, the return spring 5 realizes the up-and-down swing and self-cleaning of the second demister 7, the moving frame 6 and the connecting rod 8 work together to ensure the overall movement and function of the second demister 7. All components cooperate with each other to complete the work of demisting and cleaning impurities from the gas, improving the working efficiency and service life of the demister. Furthermore, when the second demister 7 is clogged, it can be easily disassembled, cleaned and replaced, ensuring the continuous and stable operation of the equipment.

[0029] In summary:

[0030] 1. When gas containing mist passes through the second demister 7 at a certain speed, the second demister 7 intercepts impurities, oil, solid particles, and other substances in the gas, causing them to adhere to the wire mesh. Under the impact of the gas, the second demister 7 moves upward along the support rod 4. Because a return spring 5 is provided at the top of the moving frame 6 of the second demister 7, when the gas pressure is low, the moving frame 6 is pushed back to its original position by the return spring 5, thereby causing the second demister 7 to swing up and down. The vibration generated by the up and down swing shakes off the impurities, oil, solid particles, and other substances adhering to the wire mesh, thus completing the interception of impurities, oil, solid particles, and other substances in the gas. This reduces the impact of impurities, oil, solid particles, and other substances in the gas on the first demister 3, which is mainly responsible for demisting, and solves the problem that impurities, oil, solid particles, and other substances in the fluid will adhere to the wire mesh.
