Description

Technical Field

[0001] This utility model relates to the field of oil separator core technology, and in particular to an oil separator core for a compressor. Background Technology

[0002] The oil separator element is a key component in a natural gas compressor used for oil-gas separation. Its main function is to effectively separate oil droplets from the gas in the oil-gas mixture produced by the compressor. Traditional oil separator elements typically use single-layer or multi-layer filter materials to separate oil droplets from the gas through physical filtration.

[0003] Although the oil separator core is designed for efficient separation of oil droplets in oil-gas mixtures, in practical applications, its separation efficiency often falls short of ideal levels due to the influence of materials, processes, and the working environment. In particular, the separation of tiny oil droplets may be ineffective, leading to excessive oil content in the compressed air and affecting the normal operation of subsequent equipment.

[0004] When the oil separator core has insufficient separation efficiency and oil droplets are not effectively trapped, it will affect the normal lubrication and cooling of the compressor, reduce performance and life. In view of this, an oil separator core for a compressor is provided. Utility Model Content

[0005] The main objective of this invention is to provide an oil separator core for a compressor, thereby addressing the problems raised in related technologies, such as insufficient separation efficiency and failure to effectively trap oil droplets, which affect the normal lubrication and cooling of the compressor, reduce performance, and shorten its lifespan.

[0006] To achieve the above objectives, according to one aspect of the present invention, an oil separator core for a compressor is provided, comprising an oil separator core having a cavity for the flow of an oil-gas mixture, a guide plate fixedly disposed on one side wall of the cavity, a first separation layer fixedly disposed on one side of the guide plate, a second separation layer fixedly disposed on one side of the first separation layer, and an oil baffle layer fixedly disposed on the other side wall of the cavity, the oil baffle layer comprising a plurality of conical layers and having a multi-layer superimposed design, for separating residual oil.

[0007] Furthermore, the guide plate is connected to the oil separator core air inlet, the guide plate is a conical surface, and several inclined guide blocks are fixedly arranged in a ring array on the guide plate.

[0008] Furthermore, one side of the first separation layer is a metal plate, and the other side of the first separation layer is a separation plate. The metal plate and the separation plate are fixedly connected, and the separation plate is made of glass fiber.

[0009] Furthermore, the second separation layer has flow channels, which include a plurality of channels arranged in a ring array, and the second separation layer is made of polyester fiber.

[0010] The layering includes a first layer, a second layer fixedly disposed on one side of the first layer, a third layer fixedly disposed on one side of the second layer, and a through hole opened through the center of the layer, the through hole being connected to the oil separator core outlet.

[0011] Furthermore, a plurality of connecting rods are fixedly provided on one side wall of the first layer, one end of the connecting rod penetrating through the second layer, and the other end of the connecting rod being fixedly connected to the side wall of the third layer.

[0012] There are gaps between the layers, the diameter of the first layer is smaller than the diameter of the second layer, and the diameter of the second layer is smaller than the diameter of the third layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the oil separator core of this compressor, a stacked oil-blocking layer is set, which greatly increases the contact area between the oil-gas mixture and the oil-blocking layer. This helps to capture and separate oil droplets in the oil-gas mixture more fully. Through the combined use of multiple separation layers and oil-blocking layers, a multi-layer filtration mechanism is formed. Each layer can serve as an adsorption surface for oil in the oil-gas mixture, thereby greatly increasing the contact area between the oil and gas and the separation material. This design helps to capture and separate oil droplets in the oil-gas mixture more fully, significantly improving the overall separation efficiency. Moreover, this progressively refined separation method helps to ensure the purity of natural gas. Attached Figure Description

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] Please see Figures 1-8 As shown, the purpose of this embodiment is to provide an oil separator core for a compressor, including an oil separator core 1. The oil separator core 1 has a cavity 11 for the flow of an oil-gas mixture. A guide plate 2 is fixedly disposed on one side wall of the cavity 11. A first separation layer 3 is fixedly disposed on one side of the guide plate 2. A second separation layer 4 is fixedly disposed on one side of the first separation layer 3. An oil baffle layer 5 is fixedly disposed on the other side wall of the cavity 11. The oil baffle layer 5 includes several conical layers and is a multi-layer stacked design, used to separate residual oil.

[0030] The oil separator core 1 housing is made of high-strength, corrosion-resistant materials such as stainless steel and aluminum alloy. These materials possess excellent mechanical properties and chemical stability, enabling them to withstand harsh working environments such as high pressure and high temperature. An oil collection port is provided at the bottom of the oil separator core 1 housing where it connects to the first separation layer 3, the second separation layer 4, and the oil-blocking layer 5. Its main purpose is to collect oil droplets adsorbed during the separation process. When the oil-gas mixture passes through the oil separator core 1, the oil droplets sink and accumulate at the bottom of the housing under gravity. The oil collection port effectively collects the oil droplets, preventing them from spreading within the cavity 11. Furthermore, the inner wall of the cavity 11 is made of glass fiber, which can easily absorb the oil flowing within the cavity 11.

[0031] The guide plate 2 is connected to the air inlet of the oil separator core 1. The guide plate 2 is a conical surface, which helps to pre-disperse the oil-gas mixture before entering the cavity 11. Several inclined guide blocks 21 are fixedly arranged in a ring array on the guide plate 2 to ensure that the oil-gas mixture is properly guided when flowing through the guide blocks 21 and dispersed to the periphery of the cavity 11. This helps to reduce the eddy and turbulence of the oil-gas mixture in the cavity 11 and improve the separation efficiency. The ring array arrangement allows the oil-gas mixture to be guided more evenly when flowing through the guide blocks 21, avoiding local over-concentration or insufficient dispersion. It also helps to improve the overall strength and stability of the guide plate 2.

[0032] One side of the first separation layer 3 is a metal plate 31 with densely packed filter holes, allowing gas to pass through smoothly while initially blocking larger oil droplets and impurities. The main function of the metal plate 31 is to withstand the impact of the oil-gas mixture and guide it to the separation plate 32 for further separation. At the same time, the metal plate 31 also supports and protects the glass fiber separation plate 32, preventing it from being damaged by direct impact. The other side of the first separation layer 3 is the separation plate 32, with the metal plate 31 fixedly connected to the separation plate 32. The separation plate 32 is made of glass fiber and is made of composite materials such as glass fiber and resin. Glass fiber has excellent filtration performance and wear resistance, and can effectively capture tiny oil droplets and impurities, while composite materials such as resin provide good adhesion and mechanical strength.

[0033] When the oil-gas mixture enters the cavity 11 from the inlet, it is first impacted and guided by the metal plate 31. The metal plate 31 evenly disperses the oil-gas mixture and guides it to the separation plate 32 for further separation. The glass fiber separation plate 32 uses its excellent filtration performance and wear resistance to capture tiny oil droplets and impurities, while the separated natural gas continues to flow to the subsequent processing unit through the channels between the fibers.

[0034] The second separation layer 4 has flow channels 41, which include several channels 42 arranged in a ring array. These channels 42 include short and long channels arranged in a ring array, ensuring that the oil-gas mixture can flow simultaneously in multiple directions, avoiding localized over-concentration or insufficient dispersion. The short channels quickly guide the oil-gas mixture into the interior of the second separation layer 4 and allow it to circulate, while the long channels provide a longer path and time, enabling the oil-gas mixture to make more thorough contact with the sidewalls of the second separation layer 4, increasing the contact area and improving separation efficiency. During flow, most of the oil is adsorbed onto the sidewalls of the flow channels 41. The second separation layer 4 is made of polyester fiber, which has excellent filtration performance, effectively capturing tiny oil droplets and impurities. Its fine and uniform fiber structure provides a large filtration area and capture points, ensuring efficient separation. Polyester fiber also has good wear resistance and durability, able to withstand the scouring and abrasion of the oil-gas mixture in the flow channels 41. These characteristics allow the second separation layer 4 to operate stably for a long time, reducing the frequency of maintenance and replacement.

[0035] When the oil and gas mixture enters the second separation layer 4, it is first guided by the flow channel 41 to achieve uniform dispersion. When the oil and gas mixture flows in the flow channel 41, it comes into full contact with the side wall of the polyester fiber. Due to the filtration performance and adsorption capacity of the polyester fiber, most of the oil droplets are adsorbed on the fiber surface or in the pores, while the separated natural gas continues to flow to the subsequent processing unit through the channels between the fibers.

[0036] The layering includes a first layer 51, a second layer 54 fixedly disposed on one side of the first layer 51, and a third layer 55 fixedly disposed on one side of the second layer 54. A through hole 52 is provided through the center of the layer, and the through hole 52 is connected to the gas outlet of the oil separator core 1, which allows the natural gas separated by the layering structure to flow out smoothly.

[0037] A number of connecting rods 53 are fixedly installed on one side wall of the first layer 51. One end of the connecting rod 53 passes through the second layer 54, and the other end of the connecting rod 53 is fixedly connected to the side wall of the third layer 55. These connecting rods 53 not only play a supporting and fixing role, but also ensure the coaxiality and perpendicularity between the layers, thereby ensuring the smooth flow of natural gas in the layered structure.

[0038] The layers are separated by gaps, which not only provide channels for natural gas flow but also allow it to fully contact the layers below, thus achieving more efficient separation. The diameter of the first layer 51 is smaller than that of the second layer 54, and the diameter of the second layer 54 is smaller than that of the third layer 55. This gradually increasing diameter design helps to ensure the uniform distribution and flow of natural gas within the layered structure. As natural gas flows from the first layer 51 to the third layer 55, its flow velocity gradually decreases, and the pressure loss is correspondingly reduced. This design not only improves separation efficiency but also extends the service life of the layered structure.

[0039] Through a multi-layered design, each layer can serve as an adsorption surface for oil in the oil-gas mixture, significantly increasing the contact area between the oil and gas and the oil-blocking layer 5, thereby improving the oil adsorption efficiency and separation effect. The tapered surface design with gradually increasing diameter not only helps the natural gas to be evenly distributed in the layered structure, but also guides the natural gas to flow smoothly through the through-hole 52 to the gas outlet, reducing the resistance and pressure loss of natural gas during flow and improving the overall efficiency of the separation system. The tapered surface design allows the natural gas to gradually diffuse and slow down during flow, thereby increasing the contact time and contact area between the oil-gas mixture and the separation material, further improving the separation efficiency.

[0040] In practical use, the oil-gas mixture first enters the cavity 11 through the air inlet of the oil separator core 1. After being dispersed to the periphery of the cavity 11 by the guide block 21 on the guide plate 2, the oil-gas mixture then enters the first separation layer 3. The metal plate 31 acts as a buffer, and the filter holes allow the gas to pass through smoothly while initially blocking larger oil droplets and impurities. Then, the separation plate 32 captures and adsorbs small oil droplets and impurities. After being initially separated by the first separation layer 3, the oil-gas mixture enters the second separation layer 4. The flow channel 41 ensures that the oil-gas mixture can flow simultaneously in multiple directions, fully contacting and adsorbing oil on the sidewall of the polyester fiber. Subsequently, the oil-gas mixture enters the oil-blocking layer 5. The oil-blocking layer 5 is a multi-layered design that can adsorb oil in the oil-gas mixture over a large area and guide natural gas to flow smoothly through the through hole 52 to the air outlet. After multi-layer separation, the pure natural gas flows out of the oil separator core 1 through the through hole 52. During the separation process, the adsorbed oil droplets sink and accumulate at the bottom of the oil separator core 1 shell under the action of gravity, preventing them from diffusing in the cavity 11.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
