Description

Technical Field

[0001] The utility model relates to skid-mounted equipment, in particular to a separator skid-mounted equipment. Background Art

[0002] Skid-mounted equipment combines pipelines, pressure vessels, control cabinets, electrical instruments, and other components into a single unit according to a specific process flow. This unit is secured to a steel structure or other structure (called a skid) through welding or bolting, achieving diverse functions. This system eliminates the need for on-site assembly and is ready for immediate use. With the development of industrial machinery in oil and gas fields, integration has become a common equipment requirement in the petrochemical and fine chemical industries. Skid-mounted equipment boasts a compact structure and minimal footprint, significantly saving space. Its aesthetically pleasing appearance significantly reduces on-site installation workload. Separator skids may include fluid storage, fluid delivery, fluid processing, and fluid control systems, integrating multiple functions within a single skid for integrated operation. For example, mobile skid separators are horizontal two- or three-phase separators that utilize high-precision, direct-display, pressure- and temperature-compensated gas flowmeters for direct and accurate natural gas flow measurement. They feature a sufficient settling zone, high separation efficiency, and sulfur-resistant design.

[0003] The publication number is CN116255128A, a skid-mounted wellhead oil, gas and water three-phase separation and metering device, which is mainly composed of a pretreatment system, a main separation system, a metering system and a control system connected in sequence. Through the unique two-stage separation technology, the device can effectively separate and accurately measure the oil, gas and water three-phase fluids produced from a single wellhead under the premise of ensuring relatively thorough separation of the gas. Based on these measurement results, key parameters such as the production, water content and gas-oil ratio of a single well can be accurately obtained, providing strong support for oilfield production management and decision-making. This skid-mounted design not only makes the device compact, easy to transport and install, but also improves the convenience and flexibility of on-site operations. It is impossible to achieve a completely unmanned workflow in the existing technology, and timely human intervention is always required when a failure occurs during the drainage and pressure regulation process. Utility Model Content

[0004] To address the above technical issues, the present invention discloses a skid-mounted separator device, comprising a skid, on which is mounted a separator body, which is equipped with an inlet pipeline, a drain passage, and a pressure regulating valve pipeline. Both the drain passage and the pressure regulating valve pipeline are provided with bypass structures. Through the above technical solution, if a problem occurs in one of the drain passage and the pressure regulating valve pipeline, the other route can be automatically activated, ensuring that production does not stop in an emergency and that the skid-mounted device can be operated unattended.

[0005] Furthermore, the drainage passage includes an electric ball valve and a second electric ball valve, which are connected by different pipes, with one open and the other closed. Through the above technical solution, the electric ball valve and the second electric ball valve in the drainage passage are both configured as automatic valves, which can be automatically opened and closed by a controller without the need for human intervention, and can automatically alarm and prompt maintenance in the event of a malfunction.

[0006] Furthermore, the drainage passage also includes a first three-way pipeline and a second three-way pipeline. The first three-way pipeline and the second three-way pipeline are located on both sides of the electric ball valve and are connected by bolts.

[0007] Furthermore, the first three-way pipeline is connected to a first elbow, the second three-way pipeline is connected to a second elbow, and a second electric ball valve is installed between the second elbow and the first elbow.

[0008] Furthermore, a first gate valve is provided between the first elbow and the first three-way pipe. A second gate valve is provided between the second three-way pipe and the second elbow. With this technical solution, the first and second gate valves can be directly closed when the second electric ball valve is repaired or replaced. This ensures that liquid does not leak during removal of the second electric ball valve, interfering with maintenance, and also ensures that the normal operation of the electric ball valve is not affected.

[0009] Furthermore, a first sliding flange is fixedly mounted on the first bent pipe, a second sliding flange is fixedly mounted on the second bent pipe, and the second sliding flange and the first sliding flange are respectively slidably connected to both ends of the second electric ball valve.

[0010] Furthermore, a first blocking ring is provided at both ends of the second electric ball valve, and a second blocking ring is fixedly mounted on the second sliding flange and the first sliding flange. After installation, the first blocking ring and the second blocking ring are in close contact. Through the above technical solution, since the distance between the first bend pipe and the second bend pipe is fixed, when replacing, it is often very troublesome due to the assembly gap. The sliding second sliding flange and the first sliding flange can be used for installation more labor-savingly and at the same time ensure sealing.

[0011] Furthermore, an explosion-proof power box is provided on one side of the separator body, and an explosion-proof box controller is connected to the explosion-proof power box for control.

[0012] Furthermore, a platform guardrail is provided on the separator body.

[0013] The beneficial effects of the present invention compared with the prior art are:

[0014] (1) Through the above technical solution, when a problem occurs in one of the drainage passage and the pressure regulating valve pipeline, the other route can be automatically started, and production will not be stopped in an emergency, ensuring that the skid-mounted equipment can be unmanned.

[0015] (2) Through the above technical solution, the electric ball valve and the second electric ball valve in the discharge passage are both set as automatic valves, which can be automatically opened and closed through the controller without the need for human intervention, and can automatically alarm and prompt maintenance when a fault occurs.

[0016] (3) Through the above technical solution, the first gate valve and the second gate valve can be directly closed when the second electric ball valve is repaired or replaced. At this time, it can be ensured that no liquid will flow out when the second electric ball valve is removed to interfere with the maintenance, and the normal operation of the electric ball valve can be ensured not to be affected.

[0017] (4) With the above technical solution, since the distance between the first bend pipe and the second bend pipe is fixed, replacement is often very troublesome due to the assembly gap. The sliding second sliding flange and the first sliding flange can be installed more labor-savingly and ensure sealing at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The separator body 3 is connected to an inlet pipeline 2, a safety valve pipeline skid 5, a drain passage 6, an explosion-proof power box 7, and a pressure regulating valve pipeline 8. The drain passage 6 and the pressure regulating valve pipeline 8 both adopt a bypass connection method. Specifically, there are two passages at a time, and when one of them fails, they can be quickly and automatically switched. A platform guardrail 4 is provided on the separator body 3 to provide protection when people are performing maintenance or inspection on the separator body 3.

[0027] In this embodiment, the discharge passage 6 specifically includes a first three-way pipeline 601 and a second three-way pipeline 603. Both sides of the first three-way pipeline 601 and the second three-way pipeline 603 are connected to the external pipeline respectively. An electric ball valve 602 is fixedly installed between the first three-way pipeline 601 and the second three-way pipeline 603. The fixed connection is connected by the flanges provided on the first three-way pipeline 601 and the second three-way pipeline 603, and then fixed by bolts. In this embodiment, four bolts are used for fixing. The first three-way pipeline 6 A first gate valve 604 is fixed at the third pipe outlet of 01 by a flange and bolts. The first gate valve 604 is a manual valve. The lower end of the first gate valve 604 is fixedly connected to the first elbow 607 by a flange and bolts. A second gate valve 605 is fixed at the third pipe outlet of the first elbow 607 by a flange and bolts. A second elbow 606 is fixed at the lower side of the second gate valve 605 by a flange and bolts. The second gate valve 605 is also a manual valve. The first gate valve 604 and the second gate valve 605 need to be closed during fault maintenance.

[0028] In this embodiment, a second sliding flange 609 is fixed on the second bend 606 by flanges and bolts, a first blocking ring 611 is fixed on the second sliding flange 609, a second electric ball valve 608 is slidably mounted on the second sliding flange 609, a first blocking ring 611 is fixedly mounted at the position where the second electric ball valve 608 is connected to the second sliding flange 609, a first sliding flange 610 is slidably mounted at the other opening of the second electric ball valve 608, a first blocking ring 611 is also provided on the first sliding flange 610, and a second blocking ring 612 is also fixedly mounted at the corresponding position of the second electric ball valve 608, the first bend 607 and the first sliding flange 610 are fixedly connected by flanges and bolts, when the first bend 607 and the first sliding flange 610 are fixedly connected and the second sliding flange 609 and the second bend 606 are fixedly connected, all the first blocking rings 611 and the second blocking rings 612 are in a compressed state, which plays a sealing role.

[0029] Working principle: The wellhead mining cut-off enters the skid-mounted equipment through the inlet pipeline 2 and flows into the separator body 3, is separated by the separator body 3, and the separated liquid phase is discharged from the skid through the drainage passage 6. In daily use, the electric ball valve 602 is in a closed state, and the first gate valve 604, the second gate valve 605 and the second electric ball valve 608 are in an open state. At this time, the drainage passage 6 can be normally drained. If the second electric ball valve 608 fails, it will be closed by the controller and the electric ball valve 602 will be opened for drainage. At the same time, an alarm will be issued to prompt the maintenance personnel to replace it. When replacing, first close the first gate valve 604 and the second gate valve 605. The first gate valve 604 and the second gate valve 60 5 can ensure that the liquid will no longer flow to the position of the second bend 606 and the first bend 607. At this time, the second electric ball valve 608 is removed and replaced. During installation, the second sliding flange 609 and the first sliding flange 610 are first brought close to each other, and then placed between the first bend 607 and the second bend 606 for fixation. In this embodiment, all positions fixed by flanges and bolts are provided with rubber gaskets for sealing to prevent leakage. The explosion-proof power box 7 can provide power source, data and control signal transmission for the entire skid-mounted equipment. The skid base 1 is equipped with a platform guardrail 4. The platform guardrail 4 is located on the top of the separator body 3 and is used by on-site construction personnel and operators to install, maintain and read the instruments on the top of the separator body 3.
