Description

Technical Field

[0001] This utility model relates to the field of oil-gas separation, and in particular to a high-efficiency multi-stage oil-gas separation device. Background Technology

[0002] During the oil extraction and refining process, crude oil carries a large amount of natural gas, or oil mist and oil droplets may be mixed into the process gas, forming an "oil-gas mixture". Therefore, an oil-gas separation device is needed to separate the "oil-gas mixture".

[0003] When separating oil and gas, since oil and gas often contain a lot of impurities, some of these impurities will stick to the surface of the filter screen during the separation process, which can easily cause blockage inside the device. Regular cleaning of the filter screen is required, which is inconvenient and results in low working efficiency. Therefore, a high-efficiency multi-stage oil and gas separation device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency multi-stage oil-gas separation device, which aims to solve the problem in the prior art that "impurities in oil and gas will stick to the surface of the filter screen, causing blockage inside the device, requiring regular cleaning of the filter screen, which is inconvenient and has low working efficiency".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency multi-stage oil-gas separation device, comprising a base, a pretreatment component fixedly connected to the upper surface of the base, the pretreatment component comprising an oil hopper fixedly connected to the upper surface of the base, a primary separation chamber fixedly connected to the upper surface of the oil hopper, a partition fixedly connected to the inner wall of the primary separation chamber, a support column fixedly connected to the left surface of the partition, a condenser plate fixedly connected to the left end of the support column, an upper baffle fixedly connected to the upper end of the partition, a refrigeration unit fixedly connected to the right surface of the partition, a pressurization component provided on the right surface of the primary separation chamber, the pressurization component comprising a channel opening fixedly connected to the right surface of the primary separation chamber, a filter element fixedly connected to the inner wall of the channel opening, an outlet pipe fixedly connected to the right surface of the outer wall of the channel opening, a protective cover fixedly connected to the lower end of the outlet pipe, a fan provided on the inner wall of the protective cover, and a separation component provided on the right surface of the ventilation pipe.

[0006] As a further description of the above technical solution:

[0007] The lower end of the condenser plate is fixedly connected to an electric slide rail, and a scraper is fixedly connected to the upper surface of the output shaft of the electric slide rail.

[0008] As a further description of the above technical solution:

[0009] A top cover is fixedly connected to the upper surface of the primary separation box, and a rotating motor is fixedly connected to the left end of the fan's output shaft.

[0010] As a further description of the above technical solution:

[0011] An air inlet pipe is fixedly connected to the left surface of the primary separation box, and a ventilation pipe is fixedly connected to the right surface of the protective cover.

[0012] As a further description of the above technical solution:

[0013] The separation assembly includes a centrifuge chamber, a spiral column is rotatably connected to the inner wall of the centrifuge chamber, a protective sleeve is fixedly connected to the upper end of the spiral column, and an air outlet is inserted into the upper surface of the separation assembly.

[0014] As a further description of the above technical solution:

[0015] An oil outlet is fixedly connected to the lower surface of the separation component, a tripod is fixedly connected to the lower surface of the oil outlet, a protective sleeve is fixedly connected to the inner wall of the centrifuge, a drive motor is installed on the inner wall of the protective sleeve, and the output shaft of the drive motor is fixedly connected to the upper surface of the spiral column.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by sending oil and gas into the pretreatment component, the refrigeration unit is started to cool the condenser plate. When the oil and gas come into contact with the condenser plate, the oil turns into oil droplets and then flows out from the oil funnel. The gas is discharged from the gap between the upper baffle and the first-stage separation box, and then enters the inner wall of the channel inlet. Impurities are filtered by the filter element, and then it enters the protective cover through the gas outlet pipe. At this time, large particulate impurities in the oil and gas are removed. Thus, the filter element is not easily clogged during the secondary separation, and the working efficiency is high.

[0018] 2. In this utility model, by starting the motor to drive the fan to rotate, the gas can be blown into the centrifuge box. Then, the spiral column is started to rotate. Due to the centrifugal force of the spiral column, the residual oil falls from the oil outlet, while the gas is discharged from the gas outlet. In this way, the oil and gas can be further separated, which can further improve the purity of the discharged gas. Attached Figure Description

A refrigeration unit 29 for cooling the condenser plate 25 is fixedly connected to the right surface of the partition plate 28. A pressurization component 3 for accelerating gas flow is provided on the right surface of the primary separation box 22. The pressurization component 3 includes a channel port 31 for guiding oil and gas through. The channel port 31 is fixedly connected to the right surface of the primary separation box 22. A filter element 32 for filtering large particulate impurities in the oil and gas is fixedly connected to the inner wall of the channel port 31. An exhaust pipe 33 is fixedly connected to the right surface of the outer wall of the channel port 31. The exhaust pipe 33 is set as an arc-shaped bend. A protective cover 34 for protecting the fan 35 is fixedly connected to the lower end of the exhaust pipe 33. A fan 35 for blowing oil and gas is provided on the inner wall of the protective cover 34. A separation component 4 for secondary separation is provided on the right surface of the ventilation pipe 11.

[0028] Reference Figure 2 - Figure 4 The lower end of the condenser plate 25 is fixedly connected to an electric slide rail 24 for driving the scraper 26. The upper surface of the output shaft of the electric slide rail 24 is fixedly connected to the scraper 26 for scraping off oil droplets. The upper surface of the primary separation box 22 is fixedly connected to a top cover 9. The left end of the output shaft of the fan 35 is fixedly connected to a rotating motor 10 for driving the fan 35. The left surface of the primary separation box 22 is fixedly connected to an air inlet pipe 6 for guiding oil and gas. The right surface of the protective cover 34 is fixedly connected to a ventilation pipe 11 for guiding gas into the separation component 4. The upper surface of the protective sleeve 42 is rotatably connected to a drive motor 44.

[0029] Reference Figure 3 - Figure 5 The separation component 4 includes a centrifuge chamber 41, a spiral column 43 rotatably connected to the inner wall of the centrifuge chamber 41, a protective sleeve 42 fixedly connected to the upper end of the spiral column 43, an air outlet 7 inserted into the upper surface of the separation component 4, an oil outlet 8 fixedly connected to the lower surface of the separation component 4, a tripod 5 fixedly connected to the lower surface of the oil outlet 8, a protective sleeve 42 fixedly connected to the inner wall of the centrifuge chamber 41, a drive motor 44 installed on the inner wall of the protective sleeve 42, and the output shaft of the drive motor 44 fixedly connected to the upper surface of the spiral column 43.

[0030] Working principle: When oil and gas enter the pretreatment component 2 and come into contact with the condenser plate 25, due to the high liquefaction temperature of the oil, it will turn into oil droplets after contacting the condenser plate 25, and then slide off the surface of the condenser plate 25 and flow out through the oil funnel 21. At this time, the gas will enter the inner wall of the channel 31 and pass through the filter element 32. At this time, large particles of impurities will be filtered by the filter element 32, and then enter the protective cover 34 through the gas outlet pipe 33. This reduces the clogging of the filter screen and improves working efficiency.

[0031] After the oil and gas have undergone preliminary separation, they enter the protective cover 34. The rotating motor 10 is started to drive the fan 35 to rotate, which blows the oil and gas into the centrifuge box 41. Then the spiral column 43 is started to rotate. Due to the centrifugal force generated by the rotation of the spiral column 43, the residual oil falls from the oil outlet 8, while the gas is discharged from the gas outlet 7. In this way, the oil and gas can be further separated, which can further improve the purity of the discharged gas.
