Description

Technical Field

[0001] The invention relates to the technical field of natural gas separation, in particular to an oil-gas separator for natural gas production. Background Art

[0002] Natural gas is stored in underground porous rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcano gas and biogenic gas, and a small amount comes from coal seams. It is a high-quality fuel and chemical raw material; the main use of natural gas is as fuel, and it can be used to make carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of a mixture of gaseous low-molecular hydrocarbons and non-hydrocarbon gases; it is mainly composed of methane (85%) and a small amount of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). It is mainly used as a fuel, and is also used as a raw material for the manufacture of chemicals such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuels, hydrogenated oil, methanol, nitric acid, synthesis gas and vinyl chloride.

[0003] In the process of natural gas production, gravity separators are often used. When the raw materials (a mixture of water, oil and natural gas) enter the interior, the direction of the raw materials is blocked by a baffle, so that the flow direction is downward and the separator works. However, the baffle is constantly impacted, which will cause the separator to be continuously impacted and easily cause the separator to shake. For long-term use, it is necessary to check the fixing status regularly. If the inspection is not in place, the separator is likely to topple over, affecting normal use. Summary of the invention

[0004] The object of the present invention is to provide an oil-gas separator for natural gas production to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solution: an oil-gas separator for natural gas production, comprising a shell, a water outlet is connected to the middle of the bottom end of the shell, an oil outlet is connected to one side of the bottom of the shell, a feed inlet is connected to one side of the middle of the shell, umbrella-shaped separation sheets are distributed on the lower and upper parts of the shell, a demister is fixed on the top of the shell, an air outlet is connected to the top of the shell located above the demister, and a stable cleaning component for stabilization is provided in the shell;

[0006] The material fed from the feed port pushes the stabilizing cleaning component to rotate, and the impact force of the material fed from the feed port is converted into the rotation of the stabilizing cleaning component. When the stabilizing cleaning component rotates, the umbrella-shaped separation piece is cleaned and the demister is scraped to remove the foam stuck on it.

[0007] Furthermore, the stable cleaning assembly includes a bottom fixed rod and an upper fixed rod respectively fixed at the bottom and upper parts of the outer shell, a rotating shaft is vertically rotatably connected between the middle parts of the bottom fixed rod and the upper fixed rod, the rotating shaft passes through the middle part of the upper fixed rod and is located below the demister, a driving plate is fixed to the outer side of the middle part of the rotating shaft corresponding to the feed inlet position, a scraper rod for cleaning the umbrella-shaped separation piece is fixed to the outer side of the rotating shaft at a position above the umbrella-shaped separation piece, and a cutting rod that forms a shear force with the upper fixed rod is fixed to the top of the rotating shaft at a position below the upper fixed rod.

[0008] Furthermore, the bottom fixing rods and the upper fixing rods are both distributed in a centrally divergent manner.

[0009] Furthermore, bristles are fixed to the bottom end of the scraper rod.

[0010] Furthermore, a blade is fixed on the top end of the cutting rod and contacts the bottom end of the upper fixing rod.

[0011] Furthermore, the stable cleaning assembly also includes a defoaming rod fixed to the top of the rotating shaft for removing foam at the bottom of the defoamer.

[0012] Furthermore, a steel wire is fixed to the top end of the defoaming rod.

[0013] Furthermore, a guide plate is fixed to the bottom end of the driving plate in a downwardly inclined manner.

[0014] Compared with the prior art, the beneficial effect achieved by the present invention is that through the use of a stable cleaning component, the impact force can be converted into the rotation of the stable cleaning component, which plays the role of a gyroscope and will not be affected by the impact force, can be used for a long time, and ensures normal use.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 , Figure 2 and Figure 3The present invention provides a technical solution: an oil-gas separator for natural gas production, comprising a shell 100, a mounting plate fixed at the bottom end of the shell 100 for fixing at the mounting position, a water outlet 200 connected to the middle of the bottom end of the shell 100, an oil outlet 300 connected to one side of the bottom of the shell 100, a feed inlet 400 connected to one side of the middle of the shell 100, umbrella-shaped separation sheets 500 are distributed at the lower and upper parts of the shell 100, and the present application is one umbrella-shaped separation sheet 500 at the lower part and two umbrella-shaped separation sheets 500 at the upper part, which can be selected according to actual use conditions, a demister 600 is fixed at the top of the shell 100, and the demister 600 is a plurality of wire mesh demister plates, an air outlet 700 is connected to the top of the shell 100 at a position above the demister 600, and a stable cleaning component 800 is provided in the shell 100;

[0039] The feeding from the feeding port 400 pushes the stabilizing cleaning component 800 to rotate, and the impact force of the feeding from the feeding port 400 is converted into the rotation of the stabilizing cleaning component 800. When the stabilizing cleaning component 800 rotates, the umbrella-shaped separation sheet 500 is cleaned and the demister 600 scrapes off the foam stuck thereon.

[0040] When in use, the raw materials enter from the feed port 400, and the entered raw materials rush toward the stabilizing cleaning component 800, causing the stabilizing cleaning component 800 to rotate, similar to a gyroscope, which can increase the stability of the entire separator. When the raw materials impact the stabilizing cleaning component 800, the direction of movement is changed, and the natural gas dissolved in the water can overflow, and then contact with the umbrella-shaped separation sheet 500, so that the natural gas dissolved in the water further overflows. The natural gas is defoamed by the demister 600 and then discharged from the gas outlet 700.

[0041] See also Figure 2 , Figure 3 and Figure 4 The stable cleaning assembly 800 includes a bottom fixed rod 801 and an upper fixed rod 802 respectively fixed at the bottom and the upper part of the shell 100, and a rotating shaft 803 is vertically rotatably connected between the middle parts of the bottom fixed rod 801 and the upper fixed rod 802. The rotating shaft 803 passes through the middle part of the upper fixed rod 802 and is located below the demister 600. A driving plate 804 is fixed to the outer side of the middle part of the rotating shaft 803 corresponding to the position of the feed port 400, and a scraper rod 805 for cleaning the umbrella-shaped separating sheet 500 is fixed to the outer side of the rotating shaft 803 at a position above the umbrella-shaped separating sheet 500, and a cutting rod 807 that forms a shear force with the upper fixed rod 802 is fixed to the top of the rotating shaft 803 at a position below the upper fixed rod 802.

[0042] When in use, the raw materials enter from the feed port 400, and the entered raw materials rush toward the driving plate 804, the raw materials are dispersed, the natural gas rises, and the liquid flows downward, so that the natural gas dissolved in the water overflows and the driving plate 804 rotates. The rotation of the driving plate 804 drives the rotating shaft 803 to rotate on the bottom fixed rod 801 and the upper fixed rod 802. The rotation of the rotating shaft 803 drives the scraper rod 805 to clean the umbrella-shaped separation sheet 500 so that the holes on the umbrella-shaped separation sheet 500 will not be blocked. At the same time, the rotation of the rotating shaft 803 drives the cutting rod 807 to rotate under the upper fixed rod 802 to break the passing foam and prevent the foam with oil from sticking to the demister 600, affecting the demister 600 The defoaming effect reduces the speed of the natural gas circulation.

[0043] The bottom fixing rod 801 and the upper fixing rod 802 are both distributed in a centrally divergent manner.

[0044] When in use, the bottom fixing rod 801 and the upper fixing rod 802 are centrally divergent, which facilitates the foam to flow upward.

[0045] See also Figure 4 Brush bristles 806 are fixed to the bottom end of the scraper rod 805 .

[0046] During use, by using the bristles 806, when the scraper rod 805 cleans the umbrella-shaped separator 500, the sticky oil in the holes of the umbrella-shaped separator 500 is cleaned without clogging.

[0047] See also Figure 4 A blade 8071 is fixed at the top of the cutting rod 807 and contacts the bottom end of the upper fixing rod 802 .

[0048] When in use, the cutting rod 807 rotates and contacts the bottom end of the upper fixed rod 802 through the blade 8071, so that foams of different sizes can be cut off.

[0049] See also Figure 1-3 The stable cleaning assembly 800 also includes a defoaming rod 808 fixed to the top of the rotating shaft 803 for removing foam at the bottom end of the defoamer 600.

[0050] Among them, a steel wire is fixed on the top of the defoaming rod 808. Through the use of the steel wire, the defoaming rod 808 can be used to clean the defoamer 600 conveniently.

[0051] See also Figure 4 A guide plate 8041 is fixed to the bottom end of the driving plate 804 at an angle downward.

[0052] During use, when the raw material impacts the driving plate 804 , the liquid flows downward through the guide plate 8041 .
