Description

Technical Field

[0001] This utility model relates to the field of crude oil processing technology, and more specifically, to an oil-water separation filter element. Background Technology

[0002] Oil dehydration refers to the process of removing water from crude oil in a free or emulsion state using physical or chemical methods, so that the water content meets specified standards. Common methods include sedimentation dehydration, thermochemical sedimentation dehydration, and combined electrochemical dehydration.

[0003] Existing methods for removing water from oil are time-consuming, costly, and inefficient. Devices that use filter elements for water removal are rare, and they are mostly used for removing water from diesel or gasoline in internal combustion engines. Moreover, the water removal rate is often limited and not high.

[0004] Chinese invention patent CN202211107083.5 discloses an oil-water separator filter element and a fuel filter, which includes an oil guide pipe, a water blocking pipe, and a filter medium. One end of the oil guide pipe is connected to an upper cover plate, and the upper cover plate forms an air collection chamber inside the oil guide pipe. The water blocking pipe has a water blocking part located inside the oil guide pipe, and the water blocking part and the inner wall of the oil guide pipe form a water settling channel. A vent pin extends axially from one end face of the water blocking part, and the vent pin connects the air collection chamber and the outside. One end of the water blocking pipe is connected to the other end of the oil guide pipe, and a lower cover plate is connected to the opening at the other end of the water blocking pipe. The filter medium is disposed around the oil guide pipe and the water blocking pipe, and both ends of the filter medium are connected to the upper cover plate and the lower cover plate, respectively. It can improve the filtration efficiency of the oil-water separator filter element when it is working and effectively discharge the gas mixed with fuel in the fuel supply system.

[0005] While this technology improves the efficiency of removing water from oil in the filter element, its complex structure, coupled with the fact that crude oil differs from fuel oil in that it has a higher viscosity, can lead to severe clogging issues due to the complex structure of this technology. This can affect the water removal rate and prevent the filter from achieving the desired water removal effect. Therefore, this technology cannot solve the technical problem of removing water from crude oil and has certain drawbacks. Utility Model Content

[0006] The purpose of this utility model is to provide an oil-water separation filter element that can achieve efficient oil-water separation and backwashing, solving the technical problem of difficult backwashing of ordinary filter elements in the prior art. Compared with the prior art, it has a simple structure, is not easy to clog, has a small oil-water separation pressure drop and high separation efficiency, and significantly reduces the processing cost and time cost of crude oil dehydration.

[0007] The embodiments of this utility model are implemented as follows:

[0008] This application provides an oil-water separator filter element, which includes a housing, comprising an outer cylinder and an outer shell pressure plate. The outer cylinder has multiple oil outlet holes A, and one end of the outer cylinder has an oil inlet, while the other end is connected to the outer shell pressure plate. A separation assembly includes several separation elements stacked sequentially within the outer cylinder. Each separation element includes a filter element support plate and filter media. The filter element support plate is disposed within the outer cylinder and has a groove structure. The filter media is disposed within the filter element support plate. Multiple oil outlet holes B are opened at the bottom of the filter element support plate, and multiple oil outlet holes C are spaced apart circumferentially on the side wall of the filter element support plate. The separation assembly achieves water removal filtration of crude oil. The separation assembly composed of multiple separation elements can perform multiple water removal filtrations on the passing crude oil. Furthermore, due to its simple structure, crude oil is less prone to clogging during passage. Gaps exist between the oil outlet holes A and C, facilitating crude oil filtration. The large number of oil outlet holes allows for faster crude oil filtration, further reducing the possibility of clogging and avoiding clogging problems.

[0009] In some embodiments of this utility model, a filter element pressure plate is provided on the separation component located at the end. A positioning ring A is provided on the side of the filter element pressure plate near the filter element support plate. The positioning ring A abuts against the bottom of the filter element support plate, and the end of the filter element pressure plate away from the positioning ring A abuts against the inner wall of the outer shell pressure plate. Multiple oil outlet holes D are provided on the positioning ring A, and the oil outlet holes D and C correspond one-to-one. The filter element pressure plate serves as an auxiliary component to seal the filter element support plate at the end, preventing the filter material from falling out. The positioning ring A, through an interference fit, can achieve the fixing and positioning functions of the filter element pressure plate and the filter element support plate. The other side of the filter element pressure plate abuts against the inner wall of the outer shell pressure plate. The pressure of the outer shell pressure plate on the filter element pressure plate achieves the compaction function of the separation component, preventing shaking or separation between the separation components. The oil outlet holes D and C correspond one-to-one, allowing crude oil to be filtered out smoothly without forming a blockage.

[0010] In some embodiments of this utility model, the above-mentioned part also includes a protrusion A, which is disposed in the filter element support plate. The protrusion A can form a certain space between each filter element support plate, so that there is a certain retention space when crude oil passes through, and prevent crude oil blockage from affecting the filtration rate.

[0011] In some embodiments of this utility model, a protrusion B is provided inside the filter element pressure plate, and the protrusion B is sleeved on the protrusion A. The protrusion B serves a positioning function. The sleeved protrusion B on the protrusion A can prevent misalignment between the filter element pressure plate and the filter element support plate, and at the same time avoid the problem of shaking between the two during operation, making the fixation more secure.

[0012] In some embodiments of this utility model, a positioning ring B is provided on the top of the filter element support plate. The positioning ring B abuts against the bottom of another filter element support plate. The positioning ring B has multiple oil outlet holes E, and the oil outlet holes E and C correspond one-to-one. The positioning ring B achieves the positioning and connection between one filter element support plate and another filter element support plate through interference fit, making the fixation between the two more secure, preventing misalignment and shaking during operation, and also providing a sealing effect when the two are fixed. The one-to-one correspondence between the oil outlet holes E and C allows crude oil to be filtered out smoothly without forming a blockage.

[0013] In some embodiments of this utility model, the top of the filter element support plate is provided with a protrusion C, which is sleeved on the protrusion A. The protrusion C serves a positioning function. The protrusion C sleeved on the protrusion A of another filter element support plate can prevent misalignment between the filter element support plate and the other filter element support plate, and at the same time avoid the problem of shaking between the two during operation, making the fixation more secure.

[0014] In some embodiments of this utility model, the above-mentioned gasket A is also included. Gasket A is sleeved on the protrusion A, and one side of gasket A abuts against the protrusion C, and the other side abuts against the inner wall of the filter element support plate. The gasket A plays a sealing role, and the protrusion C and the inner wall of the filter element support plate are sealed by the gasket A to prevent crude oil from filtering out from the gap between the protrusion A and the protrusion C. At the same time, it can also play a buffering role, reducing the wear between the protrusion C and the inner wall of the filter element support plate, and increasing the service life of the equipment.

[0015] In some embodiments of this utility model, the above also includes a washer B, which is annular and abuts against the inner wall of the filter element support plate. The washer B can fix the filter material and reduce the shaking and misalignment of the filter material during operation. The annular washer B can surround the filter material inside to fix and protect it, preventing direct contact between the filter material and the side wall of the filter element support plate, thereby blocking the oil outlet C.

[0016] In some embodiments of this utility model, the outer cylinder is provided with a plurality of bolt holes A, and the outer shell pressure plate is also provided with a plurality of bolt holes B. The outer cylinder and the outer shell pressure plate are connected by bolts. The bolt connection makes the fixation between the outer cylinder and the outer shell pressure plate more secure, and at the same time prevents the two from shaking and misaligning during operation. The detachable connection method also facilitates the replacement of filter media and equipment maintenance. At the same time, the bolt connection also allows the outer shell pressure plate to achieve a compaction effect on the filter element pressure plate and the separation component, thereby improving the stability of the equipment during operation.

[0017] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0018] 1. By using multiple separation elements in the separation assembly, crude oil can be filtered multiple times, thereby improving the efficiency of crude oil dehydration.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please refer to Figure 1-5 , Figure 1 The diagram shown is a schematic representation of the overall structure of an embodiment of this utility model. Figure 2 The image shown is an enlarged view of the structure at point A in an embodiment of this utility model; Figure 3 The image shown is a front view of an embodiment of this utility model; Figure 4 The figure shown is a cross-sectional view of the structure at point B in an embodiment of this utility model; Figure 5 The image shown is an enlarged view of the structure at point C in an embodiment of this utility model.

[0037] This embodiment provides an oil-water separator filter element, which includes a housing, comprising an outer cylinder 100 and an outer shell pressure plate 160. The outer cylinder 100 is provided with multiple oil outlet holes A180, and one end of the outer cylinder 100 is provided with an oil inlet 190, and the other end is connected to the outer shell pressure plate 160. The separator assembly includes a plurality of separator components stacked sequentially inside the outer cylinder 100. The separator components include a filter element support plate 110 and a filter material 140. The filter element support plate 110 is disposed inside the outer cylinder 100 and has a groove structure. The filter material 140 is disposed inside the filter element support plate 110. The bottom of the filter element support plate 110 is provided with multiple oil outlet holes B112, and the side wall of the filter element support plate 110 is provided with multiple oil outlet holes C113 spaced apart circumferentially.

[0038] As attached Figure 1-5 As shown, in order to improve the dehydration efficiency of crude oil, a separation component is provided. The separation component contains multiple separation elements. The separation component composed of multiple separation elements can filter the crude oil through multiple times to remove water. At the same time, due to its simple structure, the crude oil is not easily blocked during the passage. There is a gap between the oil outlet A180 and the oil outlet C113, which facilitates the filtration of crude oil. Moreover, the large number of oil outlets makes the crude oil filtration faster, further reducing the possibility of crude oil blockage and avoiding the blockage problem.

[0039] It should be noted that the filter media 140 is a common oil-water removal filter media 140. Any filter media 140 that can achieve the effect of removing water from oil can be used and is available on the market. No restrictions are made here.

[0040] To improve the crude oil filtration rate, the above also includes a protrusion A111, which is disposed inside the filter element support plate 110.

[0041] The protrusion A111 allows a certain space to be formed between the filter element support plates 110, so that there is a certain amount of retention space when crude oil passes through, preventing crude oil blockage and affecting the filtration rate.

[0042] In order to make the outer cylinder 100 and the outer shell pressure plate 160 more secure, the outer cylinder 100 is provided with multiple bolt holes A170, and the outer shell pressure plate 160 is also provided with multiple bolt holes B161. The outer cylinder 100 and the outer shell pressure plate 160 are connected by bolts.

[0043] The bolted connection makes the outer cylinder 100 and the outer shell pressure plate 160 more secure, and prevents them from shaking or misaligning during operation. The detachable connection also makes it easy to replace the filter media 140 and maintain the equipment. At the same time, the bolted connection also allows the outer shell pressure plate 160 to compact the filter element pressure plate 150 and the separation components, thereby improving the stability of the equipment during operation.

[0044] In use, this device is placed horizontally in the oil dehydration equipment. The oil outlet of the oil dehydration equipment is connected to the oil inlet 190 of this device. Crude oil enters the separation component through the oil inlet 190, and enters the filter element support plate 110 through the oil outlet B112. It then contacts the filter material 140 to remove water. The dehydrated crude oil enters through the oil outlet B112 of the next filter element support plate 110 for dehydration again. This cycle continues. The dehydrated crude oil seeps out through the oil outlet C113 on the side wall of the filter element support plate 110 and is discharged from this device through the oil outlet A180.

[0045] Example 2

[0046] Based on Example 1, please refer to Figure 1-6 , Figure 6 The diagram shown is a schematic diagram of the filter element pressure plate 150 according to an embodiment of the present invention.

[0047] This embodiment provides an oil-water separator filter element. A filter element pressure plate 150 is provided on the separation element located at the end. A positioning ring A152 is provided on the side of the filter element pressure plate 150 near the filter element support plate 110. The positioning ring A152 abuts against the bottom of the filter element support plate 110. The end of the filter element pressure plate 150 away from the positioning ring A152 abuts against the inner wall of the outer shell pressure plate 160. A plurality of oil outlet holes D151 are opened on the positioning ring A152. The oil outlet holes D151 and oil outlet holes C113 correspond one-to-one.

[0048] The aforementioned filter element pressure plate 150 serves as an auxiliary component, used to seal the end of the filter element support plate 110 to prevent the filter media 140 from falling out. The positioning ring A152, through an interference fit, can fix and position the filter element pressure plate 150 and the filter element support plate 110. The other side of the filter element pressure plate 150 abuts against the inner wall of the outer shell pressure plate 160. The pressure of the outer shell pressure plate 160 on the filter element pressure plate 150 achieves the compaction of the separation components, preventing shaking or separation between the separation components. The oil outlet holes D151 and C113 correspond one-to-one, allowing crude oil to be filtered out smoothly without forming blockages.

[0049] In order to make the filter element pressure plate 150 and the filter element support plate 110 more securely fixed, a protrusion B153 is provided inside the filter element pressure plate 150, and the protrusion B153 is sleeved on the protrusion A111.

[0050] The protrusion B153 serves a positioning function. The protrusion B153 is fitted onto the protrusion A111 to prevent misalignment between the filter element pressure plate 150 and the filter element support plate 110, and also avoids the problem of shaking between the two during operation, making the fixation more secure.

[0051] When in use, align the protrusion B153 of the filter element pressure plate 150 with the protrusion A111 in the end filter element support plate 110, and fit the protrusion B153 onto the protrusion A111. Press the filter element pressure plate 150 until the positioning ring A152 is embedded in the filter element support plate 110. At the same time, align the multiple oil outlet holes D151 and multiple oil outlet holes C113 one by one to complete the installation.

[0052] Example 3

[0053] Based on the above embodiments, please refer to Figure 1-5 and Figure 7 , Figure 7 The diagram shown is a schematic diagram of the filter element support plate 110 of this utility model embodiment. This embodiment provides an oil-water separation filter element. The top of the filter element support plate 110 is provided with a positioning ring B116. The positioning ring B116 abuts against the bottom of another filter element support plate 110. The positioning ring B116 is provided with a plurality of oil outlet holes E114. The oil outlet holes E114 and the oil outlet holes C113 correspond one-to-one.

[0054] As attached Figure 7 As shown, the positioning ring B116 achieves the positioning and connection between one filter element support plate 110 and another filter element support plate 110 through interference fit, making the fixation between the two more secure, preventing misalignment and shaking during operation, and also providing a sealing effect when the two are fixed. The oil outlet holes E114 and C113 are set one-to-one to allow crude oil to be filtered out smoothly without forming a blockage.

[0055] As attached Figure 7 As shown, in order to strengthen the connection between the filter element support plates 110, a protrusion C115 is provided on the top of the filter element support plate 110, and the protrusion C115 is sleeved on the protrusion A111.

[0056] The protrusion C115 serves a positioning function. The protrusion C115 is sleeved on the protrusion A111 of the other filter element support plate 110 to prevent misalignment between the filter element support plate 110 and the other filter element support plate 110, and at the same time avoids the problem of shaking between the two during operation, making the fixation more secure.

[0057] To improve the sealing between the protrusion C115 and the protrusion A111, the above also includes a washer A130, which is sleeved on the protrusion A111, with one side of the washer A130 abutting against the protrusion C115 and the other side abutting against the inner wall of the filter element support plate 110.

[0058] The gasket A130 serves a sealing function, allowing the protrusion C115 to seal against the inner wall of the filter element support plate 110, preventing crude oil from filtering out through the gap between the protrusions A111 and C115. It also acts as a buffer, reducing wear between the protrusion C115 and the inner wall of the filter element support plate 110, and increasing the service life of the equipment.

[0059] To secure the filter media 140, the above also includes a gasket B120, which is annular and abuts against the inner wall of the filter element support plate 110.

[0060] The gasket B120 can fix the filter media 140 and reduce the shaking and misalignment of the filter media 140 during operation. The annular gasket B120 can surround the filter media 140 inside to fix and protect it, and prevent the filter media 140 from direct contact with the side wall of the filter element support plate 110, thereby blocking the oil outlet C113.

[0061] In use, place gasket A130 on protrusion A111 and abut against the inner wall of filter element support plate 110. Then place gasket B120 in filter element support plate 110, with the outer wall of gasket B120 abutting against the inner wall of filter element support plate 110.
