Description

Technical Field

[0001] This utility model relates to the field of oil-gas separator technology, specifically an oil-gas separator for oil-gas pipelines. Background Technology

[0002] An oil-gas separator is a device that separates oil from associated gases. It separates free gases from oil, thereby reducing the impact of gases on pipelines as they flow with the oil, preventing cavitation and gas lock, and ensuring the normal operation of the pipeline, thus extending its service life.

[0003] According to the public announcement (CN216320876U), an oil-gas separator for oil and gas pipelines is disclosed. This technology discloses technical solutions such as "the guide hood and guide strip can be used to drive the guide hood to rotate when oil and gas are input, thereby increasing the flow of oil and gas and increasing the separation efficiency of oil and gas. The oil mist generated during the separation process will be initially isolated when passing through the top plate, and the mist eliminator will filter the remaining oil again, so that the oil can be collected and recovered." It has technical effects such as "avoiding discharge with the gas outlet pipe, affecting the return effect, and the top pipe will discharge the small amount of residual gas discharged during the filtration in the installation cylinder, thereby avoiding discharge with the oil outlet pipe and further improving the separation effect."

[0004] However, after prolonged use, the oil-gas separator experiences an increase in pressure differential as the filter element ages, necessitating periodic replacement of the oil-gas separator filter element. In contrast, the filter element in the aforementioned solution cannot be removed, requiring the entire oil-gas separator to be replaced, resulting in additional costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oil-gas separator for oil-gas pipelines, which features a filtration mechanism that can be disassembled and installed along with the upper and lower cylinders of the separator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil-gas separator for oil and gas pipelines, comprising a separator cylinder, a filter mechanism installed inside the separator cylinder, and a fixing mechanism on the separator cylinder for fixing the installed filter mechanism, the fixing mechanism comprising:

[0007] The limiting assembly includes a limiting seat fixed inside the lower cylinder of the separator cylinder and a limiting ring slidably installed inside the limiting seat;

[0008] The positioning assembly includes four positioning heads rotatably mounted circumferentially inside the limiting seat. Guide blocks are fixed to the lower ends of the positioning heads. A filter mechanism is mounted on the fixing mechanism for filtering the oil.

[0009] Preferably, the filtration mechanism includes a filter element mounted on a limiting seat. The upper and lower ends of the filter element are respectively fixed with an upper mounting seat and a lower mounting seat. The outer wall of the lower mounting seat is fixed with four circumferentially distributed positioning grooves for fixing the lower end of the filtration mechanism. The top of the upper mounting seat is provided with four circumferentially distributed insertion holes.

[0010] Preferably, a connecting plate is installed inside the lower cylinder of the separator body to fix the oil separator plate and the air collecting cylinder. Four circumferentially distributed plugs are fixed at the bottom of the connecting plate to position the upper end of the filter mechanism.

[0011] Preferably, the upper end of the connecting plate is fixed with a flow guide frame for guiding the flow of oil during input.

[0012] Preferably, the upper cylinder of the separator is provided with an air collecting cylinder inside, and oil separating plates are fixed at both the upper and lower ends of the air collecting cylinder. The oil separating plate at the upper end is fixedly connected to the inner wall of the upper cylinder of the separator. An oil and gas conveying pipe is provided at the upper end of the separator, and an oil discharge pipe is provided at the lower end of the separator.

[0013] Preferably, the guide block is located inside the outer wall of the limiting ring and is used for driving guidance.

[0014] Beneficial effects

[0015] This utility model provides an oil-gas separator for oil-gas pipelines. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] (1) When the filter mechanism is replaced, the upper and lower cylinders of the separator are disassembled and separated. The connecting plate is then removed from the lower cylinder of the separator to release the fixation on the upper end of the filter mechanism. The filter mechanism is then pulled upward to release the fixation on the lower end of the filter mechanism, so that the filter mechanism can be removed from the lower cylinder of the separator. After the upper and lower cylinders of the separator are disassembled, the filter mechanism inside can be removed together.

[0018] (2) When the filter mechanism is installed, the lower mounting base of the filter element is inserted into the inside of the limiting ring, and then the connecting plate is installed into the lower cylinder of the separator. When the upper and lower cylinders of the separator are installed, the upper cylinder pushes the connecting plate downward to drive the filter mechanism to move downward, so that the filter mechanism pushes the limiting ring downward. The limiting ring drives the positioning component to flip inward, thereby fixing the lower end of the filter mechanism. After the upper and lower cylinders of the separator are fixed, the filter mechanism inside can be connected and fixed together. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution for an oil-gas separator for oil and gas pipelines: an oil-gas separator for oil and gas pipelines includes a separator cylinder 1, a filter mechanism 3 installed inside the separator cylinder 1, and a fixing mechanism 2 provided on the separator cylinder 1 for fixing the installed filter mechanism 3. The fixing mechanism 2 includes:

[0027] The limiting component 21 includes a limiting seat 211 fixed inside the lower cylinder of the separator cylinder 1, and a limiting ring 212 slidably installed inside the limiting seat 211.

[0028] The positioning assembly 22 includes four positioning heads 221 rotatably mounted inside the limiting seat 211 and distributed circumferentially. The lower end of the positioning head 221 is fixed with a guide block 222. The fixing mechanism 2 is equipped with a filter mechanism 3 for filtering oil.

[0029] In this embodiment, when replacing the filter mechanism 3, the upper and lower cylinders of the separator cylinder 1 are disassembled and separated, the connecting plate 4 is removed from the lower cylinder of the separator cylinder 1, the upper end of the filter mechanism 3 is released from fixation, and the filter mechanism 3 is pulled upwards, so that the fixing mechanism 2 is released from fixation of the lower end of the filter mechanism 3, thereby the filter mechanism 3 can be removed from the lower cylinder of the separator cylinder 1.

[0030] Specifically, the filter mechanism 3 includes a filter element 31 installed on the limiting seat 211. The upper and lower ends of the filter element 31 are respectively fixed with an upper mounting seat 33 and a lower mounting seat 32. The outer wall of the lower mounting seat 32 is fixed with four circumferentially distributed positioning grooves 34 for fixing the mechanism 2 to position the lower end of the filter mechanism 3. The top of the upper mounting seat 33 is provided with four circumferentially distributed insertion holes 35.

[0031] In this embodiment, when the filter mechanism 3 is installed, the lower mounting base 32 at the lower end of the filter element 31 is inserted into the inside of the limiting ring 212, and then the connecting plate 4 is installed into the inside of the lower cylinder of the separator cylinder 1. When the upper cylinder and the lower cylinder of the separator cylinder 1 are installed, the upper cylinder pushes the connecting plate 4 downward to drive the filter mechanism 3 to move downward, so that the filter mechanism 3 pushes the limiting ring 212 downward. The limiting ring 212 drives the positioning component 22 to flip inward, thereby fixing the lower end of the filter mechanism 3.

[0032] Specifically, a connecting plate 4 is installed inside the lower cylinder of the separator cylinder 1 to fix the oil separator plate 7 and the air collecting cylinder 8. Four circumferentially distributed plugs 5 are fixed at the bottom of the connecting plate 4 to position the upper end of the filter mechanism 3.

[0033] In this embodiment, after the filter mechanism 3 is installed on the fixing mechanism 2, the connecting plate 4 is installed inside the lower cylinder of the separator cylinder 1. At the same time, the plug 5 at the bottom of the connecting plate 4 is inserted into the socket 35, thereby fixing the upper end of the filter mechanism 3.

[0034] Specifically, the upper end of the connecting plate 4 is fixed with a flow guide 6 for guiding the oil input. The inside of the upper cylinder of the separator cylinder 1 is provided with a gas collecting cylinder 8. Both the upper and lower ends of the gas collecting cylinder 8 are fixed with oil separating plates 7, and the upper oil separating plate 7 is fixedly connected to the inner wall of the upper cylinder of the separator cylinder 1. The upper end of the separator cylinder 1 is provided with an oil and gas conveying pipe 9, and the lower end of the separator cylinder 1 is provided with an oil discharge pipe 10.

[0035] In this embodiment, oil and gas are input into the interior of the separator cylinder 1 through the oil and gas delivery pipe 9, and after falling onto the guide frame 6 through the connecting plate 4, they enter the filter mechanism 3 for filtration. The filtered oil is discharged from the oil drain pipe 10, and the free gas in the process is discharged from the gas pipe above through the gas collecting cylinder 8 in conjunction with the oil separating plate 7.

[0036] Specifically, the guide block 222 is located inside the outer wall of the limiting ring 212 and is used for driving guidance;

[0037] In this embodiment, since the guide block 222 is located inside the limiting ring 212 and can move, the positioning head 221 can be driven to rotate through the guide block 222 when the limiting ring 212 moves up and down.

[0038] The working principle and usage process of this utility model are as follows: First, oil and gas are input into the interior of the separator cylinder 1 through the oil and gas delivery pipe 9. After falling onto the guide frame 6 through the connecting plate 4, they enter the filter mechanism 3 for filtration. The filtered oil is discharged from the oil drain pipe 10, and the free gas in the process is discharged from the gas pipe above through the gas collecting cylinder 8 in conjunction with the oil separating plate 7.

[0039] When replacing the filter mechanism 3, the upper and lower cylinders of the separator cylinder 1 are disassembled and separated, the connecting plate 4 is removed from the lower cylinder of the separator cylinder 1, the upper end of the filter mechanism 3 is released from the fixation, and the filter mechanism 3 is pulled upwards, so that the fixing mechanism 2 is released from the lower end of the filter mechanism 3, and the filter mechanism 3 can be removed from the lower cylinder of the separator cylinder 1.

[0040] When installing the new filter mechanism 3 after replacement, insert the lower mounting base 32 at the lower end of the filter element 31 into the inside of the limiting ring 212, then install the connecting plate 4 into the inside of the lower cylinder of the separator cylinder 1, and finally install the upper and lower cylinders of the separator cylinder 1. Push the plug 5 at the bottom of the connecting plate 4 downward by the upper cylinder and insert it into the socket 35, thereby fixing the upper end of the filter mechanism 3. At the same time, the connecting plate 4 also pushes the filter mechanism 3 downward, causing the filter mechanism 3 to push the limiting ring 212 downward. The limiting ring 212 drives the positioning component 22 to flip inward, thereby fixing the lower end of the filter mechanism 3. After the upper and lower cylinders of the separator cylinder 1 are fixed, the filter mechanism 3 inside can be fixed together.
