Description

Technical Field

[0001] This utility model relates to the field of gravity separator technology, specifically to a separator inlet filter element. Background Technology

[0002] Gravity separators, as key equipment for gas-solid / gas-liquid separation, are widely used in petrochemical, environmental protection and dust removal fields. They mainly rely on density differences to achieve media separation and play an important role in pretreatment or deep purification in many industrial production processes. They are indispensable for ensuring the stable operation of subsequent processes and improving product quality.

[0003] In conventional gravity separator designs, a baffle plate is typically installed at the air inlet (see reference). Figure 1 For example, the gravity separator guide plate structure disclosed in patent CN217119758U. The main purpose of the guide plate design is to buffer the high-speed fluid entering the separator from the inlet by changing the flow direction and velocity distribution of the fluid. When the fluid impacts the anti-impact baffle, its kinetic energy is consumed to a certain extent, and the flow state changes from turbulent to relatively stable, thereby avoiding direct impact of the fluid on the internal components of the separator, reducing the risk of equipment damage due to fluid impact, and extending the service life of the equipment.

[0004] While baffles can provide some buffering, they have significant limitations: they only buffer the fluid and lack effective filtration and interception capabilities for large particles carried in the fluid. In actual industrial production, the fluid entering a gravity separator often contains particles of various sizes, with the presence of large particles causing a series of serious problems. Firstly, large particles easily deposit in localized areas within the separator. Over time, these deposited particles accumulate and form blockages, severely affecting normal fluid flow and significantly reducing the separator's efficiency. Secondly, the flow of large particles within the equipment causes wear and tear on the separator's inner walls and internal components. This wear not only shortens the equipment's lifespan and increases maintenance costs but can also lead to equipment malfunctions, production interruptions, and substantial economic losses for the company.

[0005] Therefore, how to improve the air intake structure of the gravity separator so that it can effectively filter large particles while buffering the fluid has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The purpose of this invention is to propose an inlet filter element for a separator, which has a simple structure and is easy to implement. It can not only buffer fluid impact and achieve balanced fluid distribution, but also filter large particles, ensuring the safe and stable operation of the equipment.

[0007] The technical solution adopted to achieve the purpose of this utility model is:

[0008] A separator inlet filter element includes a support device, a buffer element, and a filter device, with the buffer element and filter device respectively fixed to the upper and lower ends of the support device; the bottom of the filter device is provided with a bearing mechanism for bearing large particles or droplets after filtration.

[0009] Furthermore, the support device is a support column, a support net, or a strip-shaped support plate.

[0010] Furthermore, it also includes a guide cylinder fixed to the upper part of the support device, and the guide cylinder is located between the buffer and the filter device.

[0011] Furthermore, the buffer is a buffer plate fixed to the upper end of the support device, and the buffer plate has several ventilation holes.

[0012] Furthermore, the filter device is a cylinder fixed to the lower end of the support device, and the cylinder has several filter holes.

[0013] Furthermore, a base plate is also provided at the bottom of the filter device.

[0014] The beneficial effects of this utility model are as follows: the buffer component of this utility model can not only reduce the flow rate and impact force, but also make the fluid distribution uniform; at the same time, the filter device can intercept particles with a diameter larger than the sieve hole, significantly reducing the risk of blockage inside the separator, and can still maintain stable filtration performance and improve system reliability even in scenarios with a lot of slag at the air inlet.

[0024] The illustrated embodiments are provided to better illustrate the present invention, but the content of the present invention is not limited to the illustrated embodiments. Therefore, non-essential improvements and adjustments made to the implementation schemes by those skilled in the art based on the above-described content of the present invention still fall within the protection scope of the present invention.

[0025] like Figures 2 to 7 As shown, a separator inlet filter element includes a support device 1, a buffer 2, and a filter device 3. The buffer 2 and the filter device 3 are respectively fixed to the upper and lower ends of the support device 1. The bottom of the filter device 3 is provided with a bearing mechanism 7 for bearing large particles or droplets after filtration.

[0026] The device of this invention is installed at the air inlet of a gravity separator, and the entire device is connected to the air inlet of the gravity separator to replace the traditional guide plate. In this invention, the support device 1 serves as the skeleton of the overall structure, used to fix the buffer component 2 and the filter device 3.

[0027] The buffer element 2 primarily functions as a buffer. When the fluid (usually gas) entering from the gravity separator's inlet comes into contact with the buffer element 2, its velocity is reduced, and the fluid distribution is balanced. To achieve this effect, in one embodiment of this invention, the buffer element 2 is designed as a plate-like structure. Specifically, the buffer element 2 is a buffer plate fixed to the upper end of the support device 1, and the buffer plate has several vent holes 5. During operation, the raw material gas entering from the inlet impacts the buffer plate upon contact with it, causing its velocity to decrease. Because the buffer plate has several vent holes 5, which are evenly distributed in an array, the fluid is divided into smaller streams by the vent holes 5 and flows downwards, reducing the flow velocity and impact force while ensuring uniform fluid distribution.

[0028] The filter device 3 is mainly used to filter large particles or droplets in the raw gas. The filtered fluid enters the separator to achieve solid-liquid separation, and the filtered large particles or droplets fall into the supporting mechanism 7 for temporary storage. To achieve the above effect, in one embodiment of this utility model, the filter device 3 is a cylindrical screen structure. Specifically, the filter device 3 is a cylinder fixed to the lower end of the support device 1, and the cylinder has several filter holes 6. The supporting mechanism 7 is a base plate set at the bottom of the filter device 3, used to receive the filtered particles or droplets. This utility model sets the filter device 3 as a screen structure, which can intercept particles with a diameter larger than the screen holes, significantly reducing the risk of blockage inside the separator. Even in scenarios with a lot of residue at the air inlet, it can still maintain stable filtration performance and improve system reliability. In one embodiment of this utility model, the filter holes 6 are only opened in the upper part of the cylindrical screen, so that the filtered large particles or droplets can be stored. The base plate and the cylindrical screen can be integrally formed, or they can be processed separately and then fixedly connected. During installation, the guide cylinder 4 is fixed to the side wall at the air inlet using bolts 8 and nuts 9, as detailed below. Figure 2 and Figure 7 As shown.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, in this utility model, the support device 1 is a support column, a support net, or a strip-shaped support plate. In actual design, when the support device 1 uses a support column or a strip-shaped support plate, the buffer 2 and the filter device 3 can be connected by vertically fixed columns or plates to form a rigid frame; if support strips are used, a distributed support network can be constructed between the buffer 2 and the filter device 3 through horizontally and vertically arranged strip structures. Both forms are fixed by welding or bolts 8 to ensure the spatial positioning stability of the buffer 2 and the filter device 3.

[0030] To facilitate operation and reduce the overall weight of the device, in a preferred embodiment of this utility model, the support device 1 is a strip-shaped support plate, and the number is two or more, which can be selected according to actual needs. To ensure the stability of the structural connection, the preferred number of the support device is four.

[0031] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, this utility model also includes a guide cylinder 4 fixed to the upper part of the support device 1, and the guide cylinder 4 is located between the buffer 2 and the filter device 3.

[0032] The guide cylinder 4 primarily guides the fluid flowing out of the buffer 2, forming a transition channel between the buffer 2 and the filter device 3. Its bottom is rigidly connected to the support device 1 via welding or bolts 8. The guide cylinder 4 and the buffer 2 form a two-stage buffer. The first stage reduces the macroscopic impact force of the fluid through the buffer 2, while the second stage eliminates microscopic flow velocity fluctuations through the guide cylinder 4, providing stable inlet conditions for the filter device 3.

[0033] In one embodiment of this utility model, a certain distance is left between the guide cylinder 4 and the filter device 3 to form a transition zone, that is, the guide cylinder 4 is not directly connected to the filter device. After the fluid is rectified by the guide cylinder 4, it enters the transition zone at an approximately uniform speed. Due to the existence of the gap, the fluid gradually reduces its flow velocity during free diffusion, which can prevent the fluid from directly impacting the filter device 3 and causing local wear of the filter device 3.

[0034] The specific working process of this utility model is as follows: After the raw gas enters through the inlet of the gravity separator, it first contacts the buffer 2 located at the upper end of the support device 1. Upon contact with the buffer 2, it impacts the buffer plate, significantly reducing its velocity. Simultaneously, because the air vents 5 on the buffer plate are evenly distributed in an array, the fluid is divided into smaller streams by the air vents 5, further reducing the flow velocity and impact force, and making the fluid distribution more uniform. The fluid treated by the buffer 2 flows into the guide cylinder 4, which guides the fluid. After being rectified by the guide cylinder 4, the fluid enters the filter device 3 at a relatively stable, uniform, and low velocity, avoiding direct high-speed impact of the fluid on the filter device 3 and reducing localized wear on the filter device 3. At the same time, the filter device 3 can effectively intercept large particles or droplets in the raw gas. The filtered fluid enters the separator, achieving solid-liquid separation.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
