Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter element technology, specifically a high-pressure gas-liquid coalescence separation filter element. Background Technology
[0002] Traditional gas-liquid coalescing filter cartridges mainly rely on multi-layer filter materials to intercept and coalesce liquid droplets in the gas. However, existing technologies have the following problems that urgently need to be addressed:
[0003] After separation, the droplets need to be discharged promptly under gravity. However, existing filter cartridges mostly employ simple flow-guiding designs for drainage, lacking efficient collection and sealing structures, which affects the separation effect. Furthermore, the connection and seal between the filter cartridge and the filter housing are poor; traditional single-ring sealing structures cannot withstand long-term gas impacts, easily leading to seal failure.
[0004] In the existing technology, although some gas-liquid separation devices use multi-layer filter materials, they are not designed with a dedicated coalescence and drainage integrated structure for gas-liquid separation conditions, and the sealing effect is insufficient, resulting in poor gas-liquid separation effect. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a filter element device that can achieve stable gas-liquid separation and has both high efficiency coalescence and reliable sealing performance.
[0006] This utility model is achieved through the following technical solution: A high-pressure gas-liquid coalescing separation filter element of this utility model includes a threaded interface, and a multi-layer coalescing mesh is fixedly arranged on the lower side of the threaded interface. The feature is that a drain hopper is fixedly arranged on the lower side of the multi-layer coalescing mesh, and a drain pipe is fixedly arranged on the lower side of the drain hopper. The threaded interface, the multi-layer coalescing mesh, the drain pipe and the drain hopper form a gas-liquid separation structure. After the liquid-containing gas passes through the multi-layer coalescing mesh, the gas is discharged upward from the threaded interface, and the liquid droplets are separated downward and fall into the drain hopper and the drain pipe.
[0007] In a further technical solution, the multi-layer coalescing mesh is provided with multiple layers of wire mesh.
[0008] In a further technical solution, a clean gas outlet is provided inside the threaded interface, and the clean gas outlet is connected to the internal space of the multi-layer coalescing network.
[0009] A further technical solution also includes a filter housing, wherein a sealing structure is provided between the drain hopper and the filter housing, a fixed sealing structure is provided between the threaded interface and the filter housing, and a gas inlet is provided inside the filter housing.
[0010] A further technical solution includes a sealing structure comprising a first sealing ring disposed on the outer surface of the drain hopper, the first sealing ring sealing the filter housing and the drain hopper.
[0011] A further technical solution includes a fixed sealing structure comprising a second sealing ring disposed on the outer surface of the threaded interface, wherein an installation hole is provided inside the filter housing, and the second sealing ring seals the installation hole and the threaded interface.
[0012] In a further technical solution, the threaded interface is threadedly connected to the end wall of the mounting hole.
[0013] In a further technical solution, a stepped groove is provided in the mounting hole, and the second sealing ring abuts against the stepped groove of the mounting hole.
[0014] The beneficial effects of this utility model are: First, it adopts the design of a drain hopper and a drain pipe, and the outer surface of the drain hopper is also provided with a first sealing ring, which seals with the filter housing, preventing gas from escaping and achieving a better coalescence effect.
[0015] Second, the bottom seal formed by the first sealing ring and the top seal formed by the second sealing ring allow the liquid gas to pass through the multi-layer coalescing network after it enters the gas inlet, thus achieving gas-liquid separation. The gas is then discharged upward from the clean gas outlet. This sealing structure greatly improves the gas guiding efficiency.
[0016] Third, a hollow structure is formed within the multi-layer coalescing network, which facilitates the upward discharge of gas on the one hand, and allows small droplets to coalesce into large droplets and be discharged downward on the other hand, thus realizing the function of gas-liquid separation. Attached Figure Description
[0017] For ease of explanation, the present invention will be described in detail below with reference to specific embodiments and accompanying drawings.
[0018] Figure 1 This is a schematic diagram of the overall structure of a high-pressure gas-liquid coalescence separation filter element according to the present invention;
[0019] Figure 2 for Figure 1 A schematic diagram at point A in the middle;
[0020] Figure 3 for Figure 1 A schematic diagram at point B in the middle;
[0021] In the figure, there are: drain pipe 11, drain hopper 12, first sealing ring 13, multi-layer coalescing mesh 14, second sealing ring 15, threaded interface 16, clean gas outlet 17, filter housing 18, gas inlet 19, and mounting hole 21. Detailed Implementation
[0022] like Figures 1-3 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationships of this utility model are consistent in the up, down, left, right, front, and back directions. It includes a high-pressure gas-liquid coalescing separator filter element, comprising a threaded interface 16, a multi-layer coalescing mesh 14 fixedly disposed below the threaded interface 16, a drain hopper 12 fixedly disposed below the multi-layer coalescing mesh 14, and a drain pipe 11 fixedly disposed below the drain hopper 12. The threaded interface 16 is connected to the internal space of the multi-layer coalescing mesh 14, the drain hopper 12 is connected to the internal space of the multi-layer coalescing mesh 14, and the drain pipe 11 is connected to the drain hopper 12. After the liquid-containing gas passes through the multi-layer coalescing mesh 14, the gas is discharged upwards from the threaded interface 16. When the droplet becomes large enough that its own gravity exceeds the upward force of the gas, it separates downwards and falls into the drain hopper 12 and the drain pipe 11, thus achieving the function of gas-liquid separation.
[0023] Advantageously, a clean gas outlet 17 is provided inside the threaded interface 16, and the clean gas outlet 17 is connected to the internal space of the multi-layer coalescing mesh 14.
[0024] Advantageously, it also includes a filter housing 18, a sealing structure between the drain hopper 12 and the filter housing 18, a fixed sealing structure between the threaded interface 16 and the filter housing 18, an installation hole 21 inside the filter housing 18, and a gas inlet 19 inside the filter housing 18. Liquid-containing gas is introduced through the gas inlet 19 and discharged upward from the threaded interface 16 after passing through the multi-layer coalescing mesh 14. The separated droplets enter the drain hopper 12 and the drain pipe 11, and then fall into the equipment.
[0025] Advantageously, the sealing structure includes a first sealing ring 13 disposed on the outer surface of the drain hopper 12, which seals the filter housing 18 and the drain hopper 12 when the drain hopper 12 is disposed inside the filter housing 18.
[0026] Advantageously, the fixed sealing structure includes a second sealing ring 15 disposed on the outer surface of the threaded interface 16, the second sealing ring 15 sealing the mounting hole 21 and the threaded interface 16, the threaded interface 16 being threadedly connected to the end wall of the mounting hole 21.
[0027] Advantageously, a stepped groove is provided in the mounting hole 21, and the second sealing ring 15 abuts against the stepped groove in the mounting hole 21.
[0028] Advantageously, the multi-layer coalescing mesh 14 contains multiple layers of wire mesh.
[0029] Advantageously, the drain pipe 11, drain hopper 12 and threaded interface 16 are made of metal materials, preferably corrosion-resistant stainless steel, or titanium alloy and other metal materials.
[0030] The working principle of the device is as follows: Liquid gas enters through gas inlet 19 and accumulates inside filter housing 18. According to the gas flow direction, it should be discharged upward from clean gas outlet 17. Therefore, the liquid gas will first pass through multi-layer coalescing mesh 14. Small droplets cannot change direction with the airflow due to inertia. They collide with the mesh in multi-layer coalescing mesh 14 and are captured. The surface tension of the liquid and the capillary action of the mesh cause the droplets to coalesce and grow larger and larger. When the accumulated droplets are large enough that their own gravity exceeds the upward force of the gas, the droplets separate from the mesh and fall. After being collected by the drain hopper 12, they enter the drain pipe 11 and then fall into the device.
[0031] The gas exits from the clean gas outlet 17 into the external space, thus achieving the purpose of gas-liquid coalescence and separation.
[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
