Description

TECHNICAL FIELD

[0001] The application belongs to the field of oil-water sedimentation equipment, and particularly relates to an oil-water mixture sedimentation and separation equipment. BACKGROUND

[0002] In current oil production, a large amount of waste oil-based mud or oil-based rock debris is generated, and after treatment, the waste produces an oil-water mixture. In order to reduce waste and pollution and realize recycling, the oil-water mixture is separated to separate out oil for recycling. However, the separated oil-water mixture is not a perfectly layered oil-water mixture, but an incompletely separated oil-water mixture, which may have an emulsification phenomenon. However, current oil-water separation equipment is used for natural separation of oil-water, and the separation time is too long, resulting in low work efficiency.

[0003] For example, the patent CN202022936866.7 adds a cleaning device to the oil-water mixture sedimentation and separation equipment. For oil-water mixtures relying on gravity sedimentation, the main separation method is still relying on an inclined inclined plate. However, the traditional oil-water separation hand is poor in separation effect for oil-water mixtures with an emulsification phenomenon, and can only be used for oil-water mixtures with poor oil-water emulsification and good separation. Therefore, similar equipment in the prior art is used for oil-water separation of oil-water mixtures after sedimentation, but has poor effect on oil-water mixtures with an emulsification phenomenon, and even needs to separately add a sedimentation and separation process. Therefore, there is a need for an oil-water mixture sedimentation and separation equipment capable of solving the problem. SUMMARY

[0004] The application provides an oil-water mixture sedimentation and separation equipment capable of better separating oil-water mixtures with an emulsification phenomenon and having better oil-water separation effect, and is particularly suitable for oil-water separation of oil-water mixtures with an emulsification phenomenon. The technical problem to be solved is that the existing oil-water separation equipment has poor separation effect on emulsified oil-water mixtures.

[0005] The technical scheme adopted by the application is as follows:

[0006] The oil-water mixture sedimentation and separation equipment comprises a shell, a partition plate, a first separation zone and a second separation zone. The inside of the shell is divided into the first separation zone and the second separation zone by the partition plate. The two ends of the shell are respectively provided with a liquid inlet and a tail water outlet. The first separation zone comprises a first oil baffle, a second oil baffle, a third oil baffle, a trash plate and a first boss. The trash plate is arranged below the first oil baffle. The bottom center of the first separation zone is provided with the first boss. The second separation zone comprises an inclined plate, a rotary plate, a first separation plate, a second separation plate and a second boss.

[0007] Further, the first oil baffle, the second oil baffle and the third oil baffle are fixedly connected to the upper surface of the machine shell, the first oil baffle is shorter than the second oil baffle, the second oil baffle is shorter than the third oil baffle, and the first oil baffle is fixedly connected to the trash baffle.

[0008] Further, the first boss is a right-angled trapezoid, the upper surface of the first boss is close to the trash baffle, and the trash baffle is provided with mesh holes.

[0009] Further, a liquid guide opening is arranged between the top of the partition plate and the top of the machine shell, a baffle is arranged in the middle of the top of the partition plate, and two baffle plates are symmetrically arranged on both sides of the liquid guide opening.

[0010] Further, an inclined plate is arranged at the liquid guide opening of the partition plate, the inclined plate is connected to a rotary plate, both ends of the rotary plate are connected to the inclined plate, and the inclined plate and the rotary plate form a spiral descending structure, and the bottom of the bottom inclined plate is connected to the first separation plate.

[0011] Further, the second separation plate is parallel to the first separation plate, a second boss is arranged at the bottom of the second separation area, the second boss is located between the first separation plate and the second separation plate, and the second boss is a trapezoidal structure.

[0012] Further, a side plate is arranged on the side surface of the inclined plate, and a flow guide boss is arranged on the upper surface of the inclined plate.

[0013] Further, a heating device is arranged in the first boss and the second boss.

[0014] Further, an upper oil outlet is arranged in the gap between the first oil baffle, the second oil baffle and the third oil baffle, a tail oil outlet is arranged at the gap between the first separation plate and the second separation plate, and a middle water outlet is arranged at the bottom of the first separation area.

[0015] Further, the trash baffle is a filter membrane.

[0016] After adopting the above structure, the following beneficial effects are achieved:

[0017] 1. The first oil baffle, the second oil baffle and the third oil baffle are used for stage oil blocking, which overcomes the problem that many single baffles cannot block completely and oil leakage is large, thereby greatly improving the blocking efficiency of surface floating oil stains and avoiding the problem that oil stains pass over the first oil baffle due to the falling of liquid when liquid enters.

[0018] 2. The trash baffle is used to intercept impurities in the liquid, which overcomes the problem that the existing sedimentation separation equipment cannot separate solid impurities contained in the liquid, thereby improving the sedimentation separation effect of the oil-water mixture.

[0019] 3、Due to the adoption of the inclined plate, the rotary plate and the side plate to form the rotary conveying line, the problem of time-consuming separation of the oil-water emulsion by the existing sedimentation separation equipment is overcome, so that the rotary conveying line reduces the flow rate of the liquid, because the slower the flow rate, the better the emulsion separation effect, so the separation effect of the emulsion can be effectively improved, and the rotary conveying mode can produce a centrifugal effect, which can effectively improve the demulsification effect of the emulsion.

[0020] 4、Due to the adoption of the first boss and the second boss to intercept the liquid, the problem of solid sediments being discharged with the bottom water is overcome, so that the solid sediments at the bottom can be intercepted by the first boss and the second boss, and the heating device arranged in the first boss and the second boss can improve the demulsification effect of the emulsion by heating, thereby improving the separation effect of the oil and water.

DETAILED DESCRIPTION

[0029] The present application will be further described below in conjunction with the drawings and specific embodiments.

[0030] As Figures 1-6 shown:

[0031] The utility model provides an oil -water mixture sedimentation separation equipment, including casing 1, baffle 2, first separation area and second separation area, first separation area and second separation area can carry out the sedimentation separation work of oil -water mixture twice through two spaces to improve the effect and quality of work, the inside of casing 1 is divided into first separation area and second separation area through baffle 2, and the both ends of casing 1 are provided with liquid inlet 15 and tail water outlet 16 respectively, and the liquid inlet 15 is used to enter the oil -water mixture, and the water after oil -water separation can be discharged through the tail water outlet 16, the first separation area includes first baffle 3, second baffle 4, third baffle 5, dirt baffle 6 and first boss 7, and the dirt baffle 6 is arranged below the first baffle 3, because there is impurity in the oil -water mixture, the solid impurities in the oil -water mixture can be conveniently intercepted through the dirt baffle 6, so as to ensure the purity of the separated oil -water, and the bottom center of the first separation area is provided with the first boss 7, and the second separation area includes inclined plate 8, rotary plate 9, first separation plate 11, second separation plate 12 and second boss 13.

[0032] The first baffle 3, the second baffle 4 and the third baffle 5 are all connected to the upper surface of the casing 1 by screws, the length of the first baffle 3 is shorter than that of the second baffle 4, and the length of the second baffle 4 is shorter than that of the third baffle 5, so that a baffle with a gradient is formed by the three baffles with increasing lengths, thereby separating the oil and water, because the separation time of oil and water is different, the baffles with different lengths are used, and when the water reaches a sufficient height, the oil in the later stage will be intercepted by the short baffle in addition to the initially entered oil -water mixture, because the oil mist mixed by gravity will be blocked by the second baffle 4, and the third baffle 5 is used for separating the naturally separated oil -water mixture, and the dirt baffle 6 is connected to the first baffle 3 by screws.

[0033] The first boss 7 is a right-angled trapezoid, and the right-angled structure can better block the solid impurities, the upper surface of the first boss 7 is close to the dirt baffle 6, and the leakage of impurities is avoided, and the dirt baffle 6 is provided with mesh holes, so that the filtering work of solid impurities can be conveniently carried out by controlling the size and density of the mesh holes, thereby ensuring the effect of the filtering work.

[0034] The liquid guide hole 21 is arranged between the top of the baffle 2 and the top of the casing 1, the baffle 20 is arranged in the middle of the top of the baffle 2, and the two liquid guide holes 21 are symmetrically arranged on both sides of the baffle 20. The two liquid guide holes 21 on the upper part of the baffle 2 can guide the oil -water mixture that has been standing for a certain time into the second separation area, so as to carry out secondary separation and standing work, so as to better carry out the sedimentation separation work.

[0035] The inclined plate 8 is arranged at the liquid guide opening 21 above the partition plate 2, the inclined plate 8 is connected with the rotary plate 9, the rotary plate 9 is connected with the inclined plate 8 at both ends, the inclined plate 8 and the rotary plate 9 form a spiral descending structure, and the bottom of the bottom inclined plate 8 is connected with the first separation plate 11. The inclined plate 8 and the rotary plate 9 form a spiral descending rotary structure, the oil-water mixture enters from the two liquid guide openings 21 of the partition plate 2, then enters the standing space through the descending spiral structure, because the slower the flow speed of the oil-water mixture, the better the demulsification effect of the oil-water mixture, therefore, the angle and length of the spiral structure can be adjusted to ensure the demulsification effect of the oil-water mixture, thereby avoiding the problem of too long settling and separation time caused by the emulsion, and greatly improving the work efficiency.

[0036] The second separation plate 12 is parallel to the first separation plate 11, the second boss 13 is arranged at the bottom of the second separation area, the second boss 13 is located between the first separation plate 11 and the second separation plate 12, and the second boss 13 has a trapezoidal structure. The first separation plate 11 and the second separation plate 12 are used for dividing the oil and water, so that the oil-water mixture can have sufficient space for settling and demulsification. It is also convenient to separate the liquid entering from the top and the oil-water mixture that has been separated and standing for a long time, so as to avoid the influence of the unseparated liquid on the separated liquid.

[0037] The side surface of the inclined plate 8 is provided with a side plate 10, the side plate 10 prevents the oil-water mixture from leaking from the side, and ensures that the liquid can move along the predetermined route. The upper surface of the inclined plate 8 is provided with a plurality of flow guide bosses 14 arranged in parallel. The plurality of flow guide bosses arranged in parallel form a grid-shaped flow guide structure. The flow guide structure can separate the oil and water. The water can settle and separate at the gap of the grid-shaped flow guide boss 14 structure because the water is in the lower layer. The flow guide boss 14 can better pretreat the subsequent settling work and improve the effect of settling and separation. Meanwhile, the flow guide boss 14 can guide the flowing oil-water mixture and avoid the liquid flowing in disorder.

[0038] The first boss 7 and the second boss 13 are internally provided with a heating device. The heating device can be used to control the temperature. Because the heat moves upward, the heating device at the bottom can effectively increase the temperature of the oil-water mixture. By controlling the appropriate temperature, the settling and separation of the oil and water can be better promoted, and the efficiency of the oil-water separation can be improved.

[0039] The gap between the first oil baffle 3, the second oil baffle 4 and the third oil baffle 5 is provided with an upper oil outlet 17, the gap between the first separation plate 11 and the second separation plate 12 is provided with a tail oil outlet 19, and the bottom of the first separation area is provided with a middle water outlet 18. The tail oil outlet 19 and the upper oil outlet 17 are used for discharging the floating oil in the upper layer, and the middle water outlet 18 and the tail water outlet 16 at the bottom are used for discharging the water.

[0040] The baffle plate 6 adopts a filter membrane. The filter membrane of the baffle plate 6 can better directly separate oil and water through the filter membrane, greatly improve the separation effect of oil and water, reduce the difficulty of sedimentation separation, and improve the working effect of sedimentation separation.

[0041] The working mode of the present example is as follows:

[0042] In use, the oil-water mixture is fed into the first separation zone of the casing 1 through the liquid inlet 15. In order to better separate the oil-water mixture, clean water can be pre-injected into the bottom of the first separation zone and the second separation zone. The oil-water mixture is filtered through the baffle plate 6 to separate the solid impurities in the oil-water mixture, thereby improving the working effect. The filtered oil-water mixture is layered in the first separation zone. Due to the cooperation of the first oil baffle 3, the second oil baffle 4 and the third oil baffle 5, the obvious layering is blocked by the first oil baffle 3, and the subsequent separated oil is blocked by the second oil baffle 4 and the third oil baffle 5, thereby greatly improving the oil-water separation effect. The liquid separated by the first separation zone is introduced into the second separation zone through the liquid guide hole 21 above the partition plate 2. The liquid is spirally rotated in the second separation zone through the cooperation of the inclined plate 8 and the rotating plate 9. By controlling the angle of the inclined plate 8 and the rotating plate 9 to reduce the flow rate of the liquid, the oil-water mixture can be better broken and the emulsion separation effect can be improved, thereby greatly improving the emulsion separation efficiency. The grid-shaped flow guide boss 14 on the inclined plate 8 can better guide the flow of the oil-water mixture, and the gaps in the grid structure can separate water, thereby preliminarily separating the oil-water mixture, pre-treating the subsequent separation work, and improving the working efficiency. The first separation plate 11 guides the broken liquid to the second separation zone for sedimentation separation. In order to avoid the pollution of the newly introduced liquid to the settled liquid, the first separation plate 11 effectively separates the liquid. The second separation plate 12 intercepts the oil separated by sedimentation.

[0043] The separated water can be discharged through the middle water outlet 18 and the tail water outlet 16, and the separated oil can be discharged through the upper oil outlet 17 and the tail oil outlet 19.

[0044] The heating device arranged at the first boss 7 and the second boss 13 can effectively increase the temperature of the oil-water mixture, thereby improving the sedimentation separation efficiency and greatly improving the working efficiency. The present application overcomes the problem of long separation time of the existing sedimentation separation equipment for emulsified oil-water mixture, improves the sedimentation separation effect, and effectively improves the breaking effect, thereby better performing the sedimentation separation work.
