Description

Technical Field

[0001] This utility model relates to the field of natural gas separation technology, specifically a natural gas separation device. Background Technology

[0002] Natural gas is a colorless, flammable mixture of hydrocarbons and non-hydrocarbons found in underground strata. It has a distinctive odor and is mainly found in oilfield gas, gas field gas, coalbed methane, mud volcano gas, and biogenic gas. Natural gas contains a large number of impurities that can damage pipelines and other equipment during transportation. Furthermore, the collected natural gas carries some liquid along with it; impurities accelerate the corrosion of pipelines and equipment, while the liquid reduces the pipeline's transportation efficiency. Therefore, it is necessary to separate impurities and liquids from the natural gas.

[0003] Most natural gas separation devices only separate high-pressure gas and liquid through baffles, which results in limited liquid separation effect. Liquid cannot be guided out in time and is easily blown away by gas into tiny particles. In addition, most natural gas separation devices only separate impurities through a single layer of filter screen, which makes the filter holes easy to be clogged by impurities. Utility Model Content

[0004] The purpose of this invention is to provide a natural gas separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a natural gas separation device, comprising a base plate, the upper surface of which is fixedly connected to a liquid separation cylinder, the inner wall of which is fixedly connected to a partition plate, the partition plate being fixedly connected to a fixed cylinder, a guide groove being formed on the inner wall of the fixed cylinder, the top of which is rotatably connected to the outer side of a rotating shaft, the top of which is fixedly connected to a transmission wheel, a motor being disposed above the liquid separation cylinder, the outer side of which is fixedly connected to blades, and the outer side of which is fixedly connected to a baffle plate, with air holes formed on the baffle plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention incorporates a liquid separation cylinder, a fixed cylinder, a guide channel, a drive wheel, blades, a baffle, and air holes. After natural gas enters through the inlet pipe, it is first separated by the liquid outside the fixed cylinder. Then, the natural gas enters the fixed cylinder, where a motor causes the blades to rotate. The centrifugal force generated by the rotating blades throws the liquid in the natural gas onto the inner wall of the fixed cylinder, where it flows downward through the guide channel and is discharged through the drain pipe. The baffle effectively enhances the separation effect of the liquid in the natural gas.

[0013] This utility model also incorporates an impurity separation cylinder, a filter cylinder, fan blades, a filter plate, and a scraper. The fan blades and filter plate rotate via a rotating shaft. The fan blades block the incoming gas, preventing damage to the filter plate and filter cylinder caused by the impact of impurities in the gas. The rotation of the filter plate and the filter cylinder effectively enhance the filtration effect on impurities in natural gas. The cleaning plate helps prevent clogging of the inner wall of the filter cylinder. Attached Figure Description

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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a natural gas separation device, including a base plate 1, the upper surface of which is welded and fixed to a liquid separation cylinder 2, the inner wall of which is welded and fixed to a partition plate 3, the partition plate 3 being welded and fixed to a fixed cylinder 4, the inner wall of which has several guide grooves 5, the top of which is rotatably connected to the outside of a rotating shaft 6, the top of which is welded and fixed to a transmission wheel 7, the top of which is welded and fixed to a fixed frame, the fixed frame being connected to a motor 8 by bolts, the outside of which is welded and fixed to several blades 9, which are spirally distributed on the outside of which are rough-surfaced, the outside of which is welded and fixed to a baffle plate 10, which is an umbrella-shaped plate with air holes 11, and the outside of which is welded and fixed to an air inlet pipe 12. The outer side of the liquid separation cylinder 2 is welded and fixed to the drain pipe 13, and the outer side of the liquid separation cylinder 2 is welded and fixed to the connecting pipe 14. The connecting pipe 14 connects the liquid separation cylinder 2 and the impurity separation cylinder 15. The upper surface of the bottom plate 1 is welded and fixed to the impurity separation cylinder 15. The inside of the impurity separation cylinder 15 is fixedly connected to the filter cylinder 16. The top of the impurity separation cylinder 15 is rotatably connected to the outer side of the rotating shaft 17 through a sealed bearing. The top of the rotating shaft 17 is welded and fixed to the transmission wheel 18. The transmission wheel 18 is connected to the transmission wheel 7 through a transmission belt. The outer side of the rotating shaft 17 is welded and fixed to the fan blade 19, which is located below the connecting pipe 14. The outer side of the rotating shaft 17 is welded and fixed to the filter plate 20. The side of the filter plate 20 is welded and fixed to the cleaning plate 21. The side of the cleaning plate 21 abuts against the inner wall of the filter cylinder 16. The outer side of the impurity separation cylinder 15 is welded and fixed to the air outlet pipe 22.

[0021] The bottom of the fixed cylinder 4 extends below the partition plate 3, and the bottom surface of the fixed cylinder 4 is located below the air inlet pipe 12. The drain pipe 13 is located below the air inlet pipe 12. The outer side of the rotating shaft 6 is rotatably connected to the liquid separator 2 through a sealed bearing. The top of the rotating shaft 6 extends above the liquid separator 2 and is welded and fixed to the drive wheel 7. The drive wheel 7 is welded and fixed to the output end of the motor 8. The motor 8 drives the drive wheel 7 and the blade 9 to rotate. The centrifugal force generated by the blade 9 is used to separate the liquid in the natural gas. The separated liquid will be thrown to the inner wall of the fixed cylinder 4 and flow downward under the guidance of the guide groove 5 until it flows out from the bottom of the liquid separator 2. The liquid is discharged through the drain pipe 13 of the part. The first drive wheel 7 is connected to the second drive wheel 18 through the drive belt. The blades 9 are arranged in a circular array around the center of the rotating shaft 6. The blades 9 are spiral plates. The baffle 10 extends downward from the center to the edge. The baffle 10 is umbrella-shaped. The connecting pipe 14 is located above the guide groove 5. One end of the connecting pipe 14 passes through the impurity separation cylinder 15 and extends into the filter cylinder 16. The umbrella-shaped baffle 10 can effectively block the natural gas, so that the liquid in the natural gas gathers at the bottom of the baffle 10 and flows down the slope of the baffle 10 to the inner wall of the fixed cylinder 4, so as to avoid the flow of natural gas affecting the liquid discharge.

[0022] Working principle: When in use, the operator introduces natural gas through the inlet pipe 12. After entering the liquid separator 2, the inlet pipe 12 impacts the outside of the fixed cylinder 4, causing some liquid to separate and flow down to the bottom of the liquid separator 2. Subsequently, the natural gas moves upward from the bottom of the fixed cylinder 4. The motor 8 causes the rotating shaft 6 to rotate, which in turn causes the blades 9 to rotate and generate centrifugal force, thus separating the liquid in the natural gas and throwing it to the inner wall of the fixed cylinder 4. Then, it flows downward on the inner wall of the guide channel 5. Subsequently, the natural gas is blocked by the baffle 10, which further separates the liquid. The gas is discharged from the gas hole 11 and enters the impurity separator 15 through the connecting pipe 14. The motor 8 drives the rotating shaft 17 and the drive wheel 18 to rotate synchronously through the transmission belt. The rotation of the fan blades 19 blocks impurities in the natural gas, preventing the impact of impurities from damaging the impurity separator 15 and the filter plate 20. The rotation of the filter plate 20 further enhances the filtration range, and together with the impurity separator 15, enhances the filtration effect of natural gas impurities.
