Description

Technical Field

[0001] The utility model relates to the technical field of oilfield wastewater treatment, in particular to a cyclone centrifuge. Background Art

[0002] Oil is the basic raw material for the development of petrochemical industry and an important strategic material for the country. It is related to the overall national economy. At the same time, oil is a non-renewable resource. The oil recovery rate is the biggest concern not only for the oil industry but also for the entire society.

[0003] Although new oil fields are constantly being discovered in my country through technological improvements and a lot of energy invested by petroleum science and technology workers, most of my country's oil fields are in the late stages of development. This is mainly because after years of exploitation, the crude oil reserves of many oil fields have been greatly reduced and the difficulty of exploitation has gradually increased. In the late stages of development, the output of oil fields tends to gradually decline, and the cost of exploitation will also increase. Therefore, it is urgent to carry out secondary and tertiary oil recovery in an all-round way.

[0004] As an effective mining technology for improving oil recovery and increasing crude oil production, polymer crude oil has been recognized worldwide for its good effects, large recovery rate improvement, high economic efficiency and other characteristics under specific conditions. However, since the produced emulsion contains polymers, the strength of the oil-water surface film is increased, and the stability of the produced emulsion is greatly improved, it becomes very difficult to break the emulsion membrane water. The previous emulsion breaking water technology can no longer meet the production needs.

[0005] Oil and water are two immiscible substances, but with the rapid development of chemical technology, a variety of active chemical reagents have been widely used. These active chemical reagents make it very easy for incompatible oil and water to form a stable emulsion under specific conditions. For industrial fields that require oil-water separation, the oil-water separation technology and cost of the emulsion are very high. The emulsion will have a great negative impact on the field. For example, if the filtered water contains oil, the difficulty and cost of sewage treatment will increase. The presence of water in the oil will affect the quality of the oil. For this reason, the present application proposes a cyclone centrifuge to solve the above problems. Utility Model Content

The inverted conical cylinder 7 is connected to a conical cylinder 8 at the bottom end of the inner cavity cylinder 2, and a high-power fan 12 is connected to the top side of the inner cavity cylinder 2. The high-power fan 12 is operated to guide the air flow through the air cylinder 11 and the inner cavity cylinder 2, so that the high-speed airflow in the centrifugal channel 3 flows downward. The infusion pipeline 28 inputs the emulsion into the top side port of the centrifugal channel 3. Under the action of the top side guide piece 1 4 and the guide piece 2 5, the airflow containing the emulsion obtains a large centrifugal force, and the collision with the threaded column 6 can break the emulsion film, so that the oil and water in the emulsion are separated due to the difference in specific gravity. In use, the wind force of the high-power fan 12 can be adjusted according to different material conditions to decompose the polymer (partially), accelerate the separation of oil and water, shorten the separation time, and add a small amount of chemical reagents to To achieve the purpose of reducing production costs and increasing output, the bottom end of the inverted conical cylinder 7 is connected to the discharge cylinder 14, and the first sealing plate 16 and the second sealing plate 17 are installed on the discharge cylinder 14. A liquid outlet pipe structure 19 is installed in the middle of the inverted conical cylinder 7. A conical water blocking plate 15 is arranged on the top side of the discharge cylinder 14, and the bottom side of the conical water blocking plate 15 is connected to the bottom side opening of the inverted conical cylinder 7 through a plurality of support rods. The conical water blocking plate 15 can block the airflow or liquid ejected from the centrifugal channel 3 to avoid impacting the first sealing plate 16, and the heavier solids will pass through the gaps between the plurality of support rods and enter the first sealing plate 16 on the top side of the discharge cylinder 14, thereby realizing the diversion of solids, liquids and airflow. The initial emulsion can be provided with a self-heating device in the infusion pipeline 28, and the steam heating of the oil field can be used. Heat, the heated emulsion can greatly improve the activity of the emulsion. Under the action of the high-pressure pump, the initial emulsion has a heating system and automatic addition of chemical reagents in the straight pipe section of the infusion pipe 28. The infusion pipe 28 has a rotating component that can make the initial emulsion roll inside and outside during the flow, so as to achieve the temperature and chemical reagent mixing when the emulsion flows in the infusion pipe 28. The initial emulsion enters the centrifugal channel 3 through the infusion pipe 28 under the temperature and chemical test fluidization state.

The emulsion not only generates a strong impact force during high-speed rotation, but alsoIt can also make solids with different densities obtain huge centrifugal force, move downward along the inner wall of the centrifugal cylinder 1 and the inner cavity cylinder 2, enter the bottom of the centrifugal cylinder 1 and then enter the inverted cone cylinder 7. A filter plate 29 is arranged on the top side of the inner cavity cylinder 2, and a plurality of S-shaped air ducts are arranged vertically in the filter plate 29 to further filter the moisture in the airflow discharged from the inner cavity cylinder 2. The S-shaped air duct increases the path of the airflow.

[0030] The guide pieces 1 4 and the guide pieces 2 5 are distributed in a ring shape, and the guide pieces 1 4 and the guide pieces 2 5 are installed on the inner wall of the centrifugal cylinder 1 , and the threaded columns 6 are distributed between the guide pieces 1 4 and the guide pieces 2 5 .

[0031] The liquid outlet pipe structure 19 is arranged corresponding to the liquid storage tank 20. The liquid storage tank 20 is provided with a pump-out pipe 21 connected to the tank body 1 22. The top side of the tank body 1 22 is connected to the tank body 2 24 through the infusion pipe 23. The pump-out pipe 21 is adapted to be equipped with an extraction pump.

[0032] Tank body 1 22 and tank body 2 24 are equipped with a storage pool 25. Exhaust pipes 26 are installed on the top of tank body 1 22 and tank body 2 24. Discharge valves 27 are installed on the bottom of tank body 1 22 and tank body 2 24. The liquid storage tank 20 enters tank body 1 22 through the pump outlet pipe 21, so that oil and water enter and separate in layers, and a small amount of solid matter exists at the bottom of tank body 1 22. Solid matter is discharged to the storage pool 25 manually from time to time, and the storage pool 25 is post-processed.

[0033] The volume of tank 1 22 and tank 2 24 is 5m 3 The separation time of solid and liquid is observed by the oil mark at the bottom of tank body 1 22 and tank body 2 24. The solid matter is discharged into the solid matter discharge pool 25 according to the actual situation, and the water is discharged through the valve. As the water on the water surface becomes smaller, it can automatically flow into tank body 2 24 when it reaches a certain level. At this time, there is a certain level of water in the oil. Tank body 24 has a heating device. After the water evaporates, it is automatically discharged through the exhaust pipe 26 above the tank body. The above operations are all controlled by the console. Except for the solid emissions that need to be manually discharged regularly, the rest can be automatically controlled and no manual intervention is required.

[0034] The air duct 11 at the air inlet end of the high-power fan 12 has an anti-static device in the air duct 11 to prevent static electricity from generating open flames. The air duct 11 is connected to the top side of the inner cavity tube 2. The exhaust port of the high-power fan 12 is connected to the exhaust duct 13, and the exhaust duct 13 discharges the exhausted gas.

[0035] The liquid outlet pipe structure 19 includes a liquid outlet pipe 191 and a sealing plate 192, and the liquid outlet pipe 191 is installed on the side wall of the inverted conical cylinder 7, and the sealing plate 192 is installed at the port of the liquid outlet pipe 191. The sealing plate 192 is made of deformable plastic material. When the water line in the inverted conical cylinder 7 is higher than the height covering the liquid outlet pipe 191, the sealing plate 192 is pushed outward by the pressure in the inverted conical cylinder 7, and the sealing plate 192 is deformed and bent outward. At this time, the port of the liquid outlet pipe 191 is in an open state to achieve liquid discharge.

[0036] Two solid discharge valves of different sizes are installed at the lower part of the inverted cone-shaped cylinder 7, namely the first sealing plate 16 and the second sealing plate 17. The first sealing plate 16 and the second sealing plate 17 are respectively distributed on the top side and the bottom side of the discharge barrel 14, and the first sealing plate 16 and the second sealing plate 17 are provided with a counterweight 18, and the counterweight 18 is connected to the adjusting rods of the first sealing plate 16 and the second sealing plate 17. The weight that the first sealing plate 16 and the second sealing plate 17 can bear can be adjusted by sliding the counterweight 18 on the adjusting rod. After a certain amount of solid matter accumulates on the upper side of the first sealing plate 16, the weight is greater than the counterweight 18, and the first sealing plate 16 will rotate with the positioning axis as the axis, so that the solid matter falls into the discharge barrel 14, and the second sealing plate 17 receives the solid matter falling from above. After a certain amount of solid matter accumulates on the upper side of the second sealing plate 17, the weight is greater than the counterweight 18, and the second sealing plate 17 will rotate with the positioning shaft as the axis. The positioning shaft is installed on the side wall of the discharge barrel 14, and the positioning shaft is set at the connection between the adjusting rod and the first sealing plate 16 and the second sealing plate 17, so that the solid matter falls to the outside of the discharge barrel 14 and is discharged. In this way, one of the first sealing plate 16 and the second sealing plate 17 is in a closed state, thereby ensuring the sealing of the inverted cone cylinder 7. The setting of the sealing plate 192 can make the sealing plate 192 push out the discharge liquid after a certain pressure is generated in the liquid outlet pipe 191, which is also used to ensure the sealing of the inverted cone cylinder 7, and the liquid is discharged through the liquid outlet pipe 191 into the external liquid storage tank 20, thereby realizing the closing or opening of the sealing plate 192 by utilizing the pressure difference.

[0037] The top side opening of the conical cylinder 8 is connected to the guide cylinder 9. The channel space of the guide cylinder 9 is smaller than that of the inverted conical cylinder 7, which plays a role in reducing the wind speed. It cooperates with the conical cylinder 8 to block water molecules. At the same time, a certain high-pressure space is guaranteed in the centrifugal channel 3 to ensure that the emulsion obtains a strong impact force when colliding with the threaded rod 6. The upper inclined surface of the conical cylinder 8 plays a flow-gathering role for the liquid, and the lower inclined surface of the conical cylinder 8 plays a blocking role for the liquid. A plurality of liquid down pipes 10 are installed at the lowest point of the upper inclined surface of the conical cylinder 8, and the bottom ends of the plurality of liquid down pipes 10 extend into the inverted conical cylinder 7. The liquid down pipes 10 are used for the liquid in the inner cavity cylinder 2 to flow down to the inverted conical cylinder 7.

[0038] The operating steps of the utility model are:

[0039] The high-power fan 17 operates to guide the air flow through the air cylinder 11 and the inner cavity tube 2, so that the high-speed air flow in the centrifugal channel 3 flows downward. The infusion pipeline 28 inputs the emulsion into the top side port of the centrifugal channel 3. Under the action of the top side guide piece 1 4 and the guide piece 2 5, the air flow containing the emulsion obtains a large centrifugal force, and the collision with the threaded column 6 can break the emulsion film, so that the oil and water in the emulsion are separated due to the difference in specific gravity. In use, the wind force of the high-power fan 12 can be adjusted according to different material conditions to decompose the polymer (partially), accelerate the separation of oil and water, shorten the separation time, and add a small amount of chemical reagents to achieve the purpose of reducing production costs and increasing output.

[0040] The initial emulsion can be provided with a self-heating device in the infusion pipeline 28, and can be heated by steam from the oil field. The heated emulsion can greatly improve the activity of the emulsion. Under the action of the high-pressure pump, the initial emulsion has a heating system and a small amount of chemical reagents are automatically added to the infusion pipeline 28. The infusion pipeline 28 has a rotating component that can make the initial emulsion roll inside and outside during the flow, so as to achieve the temperature and chemical reagent mixing when the emulsion flows in the infusion pipeline 28. The initial emulsion enters the centrifugal channel 3 through the annular section of the infusion pipeline 28 under the temperature and chemical test fluidization state, and in the high-power Under the action of the rotating blades of the high-speed fan 12, a wind speed of 30m / s is generated to enter the centrifugal channel 3, and under the action of the guide blade 4, it rotates and descends, hitting the large number of threaded columns 6 in the centrifugal channel 3 to obtain a strong impact force. The emulsion not only generates a strong impact force during high-speed rotation, but also enables solids with different densities to obtain huge centrifugal force, move downward along the inner wall of the centrifugal cylinder 1 and the inner cavity cylinder 2, and enter the bottom of the centrifugal cylinder 1 and then enter the inverted cone cylinder 7. The lower part of the inverted cone cylinder 7 is equipped with two solid discharge valves of different sizes, that is, the first sealing The blocking plate 16 and the second blocking plate 17, after a certain amount of solid matter accumulates on the upper side of the first blocking plate 16, the weight is greater than the counterweight 18, the first blocking plate 16 will rotate with the positioning axis as the axis, so that the solid matter falls to the discharge barrel 14, the second blocking plate 17 receives the solid matter falling from above, after a certain amount of solid matter accumulates on the upper side of the second blocking plate 17, the weight is greater than the counterweight 18, the second blocking plate 17 will rotate with the positioning axis as the axis, so that the solid matter falls to the outside of the discharge barrel 14 for discharge, the two counterweights 18 are not located on the outer sides of the first blocking plate 16 and the second blocking plate 17 The same is achieved in this way, that the weight of solid matter accumulated when the first sealing plate 16 and the second sealing plate 17 are opened is different. After the device is adjusted, the weight of solid matter required for the second sealing plate 17 is greater, so that the first sealing plate 16 and the second sealing plate 17 are not opened at the same time, so that one of the first sealing plate 16 and the second sealing plate 17 is in a closed state, thereby ensuring the sealing of the inverted cone cylinder 7. The setting of the sealing plate 192 can push the sealing plate 192 out to discharge liquid after a certain pressure is generated in the liquid outlet pipe 191, which is also used to ensure the sealing of the inverted cone cylinder 7.

[0041] The liquid storage tank 20 enters the tank body 22 through the pump outlet pipe 21, so that the oil and water enter and separate in layers, and a small amount of solid matter exists at the bottom of the tank body 22. The solid matter is discharged to the storage tank 25 manually at irregular intervals for post-processing of the storage tank 22.

[0042] The volume of tank 1 22 and tank 2 24 is 5m 3 The separation time of solid and liquid is determined by observing the oil marks at the bottom of tank body 1 22 and tank body 2 24. The solids are discharged into the solid discharge pool 25 according to the actual separation situation of the solids and liquids, and the water is discharged through the valve. As the oil ratio becomes smaller, when it reaches a certain level on the water surface, it can automatically flow into tank body 2 24. At this time, there is a certain level of water in the oil. Tank body 24 has a heating device. After the water evaporates, it is automatically discharged through the exhaust pipe 26 above tank body 24. The above operations are all controlled by the console. Except for the solid emissions that need to be manually discharged regularly, the rest can be automatically controlled and no manual intervention is required.
