A two-phase impact type eccentric tube acceleration separation equipment

Abstract

The present invention discloses a two-phase impact type eccentric tube acceleration separation device, which is equipped with an eccentric sleeve structure, a floating oil tree-shaped pipeline, an acceleration impact structure and a movable air flotation separation component. The acceleration impact structure provides an acceleration transportation driving force for the sinking water body, and transports gas to the inside of the water body in an accelerated state. The gas forms micro bubbles in the water body, combines with the oil body and floats up. The water body in the accelerated state collides with the gas to form an air flotation impact area. The acceleration impact structure can be movable to transport gas to different positions in the air flotation impact area. The present invention avoids the situation that the oil and water phases are not separated in time due to too fast flow rate, and the oil body follows the water body into the lower eccentric sleeve and cannot float up in time and is discharged through the floating oil tree-shaped pipeline. In addition, the combination of gas and oil is accelerated in the air flotation impact area, thereby improving the oil-water separation efficiency. Under the condition of ensuring the working efficiency of oil-water separation, the corresponding oil-water separation efficiency is improved through the gas impact effect and the air flotation effect.

Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation, and in particular to a two-phase impact type eccentric tube acceleration separation device. Background Art

[0002] The petrochemical industry usually needs to perform oil-water separation work. T-type bifurcations are widely used in the petrochemical industry. T-type bifurcations can be used as two-phase separators. When two phases with different densities flow through the T-type bifurcations, the two-phase flows are unevenly distributed and the two phases flow into different pipes. Current research is mostly focused on the application of T-type bifurcations in gas-liquid separation.

[0003] Compared with the gas-liquid two phases, the density difference between the oil-water two phases is very small, and it is difficult to achieve good separation with a conventional T-type bifurcated pipeline. For this reason, there is also an eccentric T-type casing in the prior art, which combines the dynamic separation principle of the T-type tube with the shallow pool distance. Specifically, it includes upper and lower layers of eccentric casings, which are connected by two risers. The oil and water phases enter the separation system from the upper inner tube, and the water phase carries a small amount of oil phase into the upper outer tube from the narrow slit at the bottom of the upper inner tube, and flows into the lower outer tube through the riser. The water phase settles to the bottom of the lower outer tube and enters the lower inner tube, and finally flows out of the separation system through the lower inner tube, and the oil phase flows out of the separation system through the upper inner tube, which is easy to carry out stratified flow of the oil and water phases.

[0004] Research has shown that the flow rate of the oil-water phases will have a great impact on the final separation efficiency. The greater the mixed flow rate, the lower the separation efficiency. Therefore, a lower flow rate is required to achieve the best separation efficiency, which has a certain impact on the working efficiency of the separation equipment itself, and it is impossible to improve the corresponding working efficiency while ensuring the best separation efficiency.

[0051] 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.

[0052] like Figure 1 As shown, the present invention provides a two-phase impact type eccentric tube acceleration separation device, which is equipped with an eccentric sleeve structure 1, a floating oil tree pipeline 2, an acceleration impact structure 3 and a movable air flotation separation element 4.

[0053] The eccentric sleeve structure 1 is arranged at the output end of sewage discharge. The eccentric sleeve structure 1 has an upper eccentric sleeve 11 and a lower eccentric sleeve 12. The upper eccentric sleeve 11 is used to receive sewage, provide a place for preliminary separation of sewage, and discharge the separated oil body after separation. The lower eccentric sleeve 12 is used to receive the separated water body after separation and discharge it.

[0054] The floating oil tree-shaped pipeline 2 is arranged between the upper eccentric casing 11 and the lower eccentric casing 12. The floating oil tree-shaped pipeline 2 is used to provide a separate pipeline 5 for floating and sinking for the oil body entering the lower eccentric casing 12 and the water body in the upper eccentric casing 11. A plurality of floating spaces 6 are formed inside the bottom of a single floating oil tree-shaped pipeline 2 near the connection with the lower eccentric casing 12, and all the floating spaces 6 are continuously connected to the top of the lower eccentric casing 12.

[0055] The accelerating impact structure 3 is arranged in the oil floating tree-shaped pipeline 2, and at least two accelerating impact structures 3 are arranged. The accelerating impact structure 3 is used to intermittently provide accelerating transportation driving force for the water body sinking from the upper eccentric sleeve 11 to the lower eccentric sleeve 12, and to transport gas to the inside of the water body in an accelerated state. The gas forms micro bubbles in the water body, combines with the oil body and floats up. The water body in the accelerated state collides with the gas in the upper part of the oil floating tree-shaped pipeline 2 to form an air flotation impact area 7. The structural end of the gas formed in the accelerating impact structure 7 can move to transport the gas to different positions in the air flotation impact area 7.

[0056] The movable air flotation separator 4 is arranged in the lower eccentric sleeve 12. The movable air flotation separator 4 is used to input gas into the lower eccentric sleeve 12 to form micro bubbles in the water body of the lower eccentric sleeve 12 to combine with the oil body, and float to the upper eccentric sleeve 11 through the floating space 6 and the separation pipeline 5.

[0057] In the embodiment of the present invention, an oil floating tree-shaped pipeline 2 is arranged between the upper eccentric sleeve 11 and the lower eccentric sleeve 12, so as to avoid the situation that the oil and water phases are not separated in time due to too fast flow rate, and the oil body follows the water body into the lower eccentric sleeve and cannot float up in time and is discharged. In addition, the water body is driven to be transported at an accelerated speed by the acceleration impact structure 3, and gas is simultaneously transported into the water body in an accelerated state. The water body in an accelerated state and the gas collide to form an air flotation impact area 7 in the upper part of the oil floating tree-shaped pipeline 2. The combination of gas and oil body is accelerated in the air flotation impact area 7, so as to improve the oil-water separation efficiency. After the water body enters the lower eccentric sleeve 12, the oil phase is repeatedly driven by the air flotation effect to separate from the lower eccentric sleeve 12. Under the condition of ensuring the working efficiency of oil-water separation, the corresponding oil-water separation efficiency is improved through the gas impact effect and the air flotation effect.

[0058] The upper eccentric sleeve 11 of the present invention is used to receive sewage, provide a place for preliminary separation of sewage, and discharge the separated oil body. Figure 2 As shown, the upper eccentric sleeve 11 includes an upper connecting outer tube 111, an upper connecting inner tube 112 arranged in the upper connecting outer tube 111, an oil floating tube 113 arranged on the upper connecting outer tube 111, and an oil overflow hole 114 arranged at the connection between the oil floating tube 113 and the upper connecting outer tube 111; the upper connecting inner tube 112 is arranged through the upper connecting outer tube 111, the top of the upper connecting outer tube 111 is connected with the inside of the oil floating tube 113 through the oil overflow hole 114, the bottom of the upper connecting inner tube 112 located in the upper connecting outer tube 111 is provided with an upper drainage slit 115, the bottom of the upper connecting inner tube 112 is connected with the inside of the upper connecting outer tube 111 through the upper drainage slit 115, and the oil floating tube 113 is provided with an exhaust hole 116; the central axis of the upper connecting inner tube 112 is located directly above the central axis of the upper connecting outer tube 111.

[0059] In the above embodiment, after entering the upper connecting inner tube 112, the sewage enters the upper connecting outer tube 111 through the upper drainage slit 115, and part of the oil floats up and enters the floating oil pipe 113 through the oil overflow hole 114, wherein the exhaust hole 116 is used to collect and discharge the gas floated during the flotation process.

[0060] The water body enters the lower eccentric sleeve 12 after passing through the upper connecting outer pipe 11. The lower eccentric sleeve 12 is used to receive the separated water body after separation and discharge it. Figure 3 As shown, the lower eccentric sleeve 12 includes a lower connecting outer tube 121 and a lower connecting inner tube 122 arranged in the lower connecting outer tube 121; the lower connecting inner tube 122 is penetrated and arranged on the lower connecting outer tube 121, and a lower drainage slit 123 is arranged at the bottom of the lower connecting inner tube 122, and the lower connecting inner tube 122 is connected to the lower connecting outer tube 121 through the lower drainage slit 123; the central axis of the lower connecting outer tube 121 is located directly above the central axis of the lower connecting inner tube 122.

[0061] The water settles to the bottom of the lower connecting outer tube 121 , and enters the lower connecting inner tube 122 through the lower drainage slit 123 , and then is discharged through the lower connecting inner tube 122 .

[0062] The oil floating tree-shaped pipeline 2 in the present invention is used to provide a separate pipeline 5 for floating and sinking for the oil body entering the lower eccentric casing 12 and the water body in the upper eccentric casing 11. The oil floating tree-shaped pipeline 2 of the present invention adopts the following preferred embodiment. The oil floating tree-shaped pipeline 2 includes an upper drainage pipe 21, a straight middle pipe 22 connected to the upper drainage pipe 21, and an upper floating pipe 23 arranged at the bottom of the straight middle pipe 22; the upper drainage pipe 21 is obliquely arranged on the upper connecting outer pipe 111 and is connected to the inside of the upper connecting outer pipe 111, the straight middle pipe 22 is connected to the upper drainage pipe 21, and a floating oil vertical pipe 24 is also arranged on the straight middle pipe 22 and is connected to the floating oil vertical pipe 24.

[0063] In the above embodiment, the upper drainage pipe 21 is mainly provided to provide a passage for water from the upper connecting outer pipe 111 to the lower connecting outer pipe 121. The water enters the upper drainage pipe 21 from the upper connecting outer pipe 111 and then enters the upper floating pipe 23, wherein the floating oil riser 24 is a passage for oil and gas to float.

[0064] In order to facilitate the floating of the oil body in the lower connecting outer tube 121, at least two floating pipes 23 are provided. The floating pipes 23 are in a vertical state or an inclined state. Only the floating pipes 23 in the inclined state are drawn in the figure. There are multiple forks in the floating pipe 23. The branched ends of the floating pipes 23 are provided with triangular tubes 25, and are connected to the lower connecting outer tube 121 through the triangular tubes 25. The floating space 6 is provided in the triangular tubes 25, and adjacent triangular tubes 25 are connected.

[0065] The existing lower connecting outer tube 121 usually has a vertical pipe arranged at equal intervals. The oil body far away from the vertical pipe and in the lower connecting outer tube 121 is difficult to float to the upper connecting outer tube 111 through the vertical pipe. Therefore, a triangular tube 25 is set at the bottom of the upper floating tube 23. The oil body at various positions in the lower connecting outer tube 121 can enter the upper floating tube 23 through the triangular tube 25 and float to the upper connecting outer tube 111.

[0066] The accelerating impact structure 3 of the present invention intermittently provides an accelerating transport driving force for the water body that sinks from the upper eccentric sleeve 11 to the lower eccentric sleeve 12, and transports gas to the water body in the accelerated state. The gas forms micro bubbles in the water body, combines with the oil body and floats up. The water body in the accelerated state collides with the gas in the upper part of the floating oil tree pipeline 2 to form an air flotation impact area 7. The structural end of the gas formed in the accelerating impact structure 7 can move to transport gas to different positions in the air flotation impact area 7. The accelerating impact structure 3 of the present invention adopts the following preferred embodiments, such as Figure 4 and Figure 5As shown, the acceleration impact structure 3 includes a mounting groove 31 arranged on the outer wall of the straight middle tube 22, a connecting shaft 32 arranged in the mounting groove 31, and an air cylinder 33 arranged between the connecting shafts 32; a pressure pump 314 is arranged on the upper drainage pipe 21, a plurality of mounting grooves 31 are arranged at equal intervals, a connecting groove 34 is arranged on the outer wall of the air cylinder 33, the connecting shaft 32 is rotatably arranged in the connecting groove 34, and the air cylinder 33 is rotatably arranged on the connecting shaft 32.

[0067] In the above embodiment, the gas cylinder 33 can transport gas into the straight middle tube 22 to form bubbles in the air flotation impact area 7. In order for the gas in the gas cylinder 33 to fully contact the water in the air flotation impact area 7, the gas cylinder 33 in this embodiment is rotatable during the gas delivery process.

[0068] In order to deliver gas into the gas cylinder 33 without affecting the rotation of the gas cylinder 33 and the sealing performance of the straight middle tube 22, the present invention further makes the following design: a sealing cylinder 35 is provided outside the straight middle tube 22, the straight middle tube 22 is penetrated and arranged on the sealing cylinder 35, and the end of the gas cylinder 33 extends to between the sealing cylinder 35 and the straight middle tube 22; a telescopic tube 36 is provided at the end of the sealing cylinder 35, the end of the telescopic tube 36 away from the sealing cylinder 35 is installed on the sealing cylinder 35, and a first vacuum pump 37 is provided at the outer end of the telescopic tube 36, and the first vacuum pump 37 is arranged outside the sealing cylinder 35.

[0069] In the above embodiment, the first vacuum pump 37 drives the gas to be transported from the telescopic tube 36 to the gas cylinder 33, and then the gas is input into the straight middle tube 22 through the gas cylinder 33. During the rotation of the gas cylinder 33, the telescopic tube 36 is in an extended or contracted state, and the airtightness inside the straight middle tube 22 is not affected.

[0070] In order to drive the gas delivery cylinder 33 to rotate to adjust the gas delivery direction, the present invention also makes the following design: Figure 6 As shown, the outer wall of the gas delivery cylinder 33 is provided with a sliding groove 38, a sliding arc block 39 is provided in the sliding groove 38, and limit blocks 310 are provided on both sides of the sliding arc block 39. The inner wall of the sliding groove 38 is provided with a clamping groove 311, and the limit block 310 is slidably set in the clamping groove 311; a control bolt 312 is rotatably set on the outer end surface of the sliding arc block 39, a control cylinder 313 is provided outside the sealing cylinder 35, the control bolt 312 is set at the output end of the control cylinder 313, and the control bolt 312 is set through the sealing cylinder 35.

[0071] In the above embodiment, the control cylinder 313 is driven to drive the control bolt 312 to move downward or upward, and the air cylinder 33 is driven to rotate under the lifting action of the control bolt 312. In the process of driving the air cylinder 33 to rotate, the sliding arc block 39 slides in the sliding groove 38.

[0072] The present invention uses a movable air flotation separator 4 to input gas into the lower eccentric sleeve 12 to form micro bubbles in the water body of the lower eccentric sleeve 12 and combine with the oil body, and float to the upper eccentric sleeve 11 through the floating space 6 and the separation pipe 5. The movable separator 4 of the present invention adopts the following preferred embodiments, such as Figure 3 and Figure 7 As shown, the movable air flotation separation element 4 includes a connecting pipe 41 that passes through the lower connecting outer tube 111, a telescopic joint 42 that is arranged on the connecting pipe 41, a movable seat 43 that is arranged on the telescopic joint 42, and a transport pipe 44 that is arranged on the movable seat 43; the transport pipes 44 are provided in plurality, a ventilation groove 45 is provided in the movable seat 43, the transport pipe 44 is connected to the inside of the telescopic joint 42 through the ventilation groove 45, and a second air pump 46 is connected to the outside of the connecting pipe 41.

[0073] The second vacuum pump 46 drives external gas to enter the connecting pipe 41, then enter the ventilation groove 45 through the expansion joint 42, and then enter the lower connecting outer pipe 121 from the transport pipe 44. Under the effect of air flotation, the oil body in the lower connecting outer pipe 121 is accelerated to float up.

[0074] In order to eliminate the oil in the water entering the lower drainage slit 123, it is necessary to make the upper end of the transport pipe 44 higher than the lower drainage slit 123, and perform flotation on the water before entering the lower drainage slit 123 to eliminate the oil as much as possible.

[0075] In order to fully contact the water body in the lower connecting outer tube 111, the angle of the transport pipe 44 in this embodiment is also movable. Specifically, the present invention makes the following design: a plurality of movable groove seats 47 are arranged at the bottom of the movable seat 43, and the movable groove seats 47 are all on a circular trajectory. A movable shaft column 48 is arranged at the bottom of the movable groove seat 47, and a fixed ball seat 49 is arranged on the movable shaft column 48. The movable groove seat 47 is rotatably arranged on the fixed ball seat 49; a lifting cylinder 410 is arranged at the bottom of the movable shaft column 48, and the movable shaft column 48 is installed at the output end of the lifting cylinder 410, and the movable shaft column 48 is arranged through the lower connecting outer tube 121.

[0076] In the above embodiment, the lifting cylinder 410 drives the movable shaft column 48 to move outward, thereby driving the fixed ball seat 49 to move outward, and the movable groove seat 47 is driven to rotate to one side through the fixed ball seat 49, and the transport pipe 44 rotates accordingly, and the gas output direction changes accordingly, thereby accelerating the lifting frequency of the corresponding lifting cylinder 410, so that the gas can contact the water body in the lower connecting outer tube 121 in a larger range and more fully.

[0077] In summary, the main implementation process of the present invention is:

[0078] Sewage is injected from the upper connecting inner tube 112. After entering the upper connecting inner tube 112, the sewage enters the upper connecting outer tube 111 through the upper drainage slit 115. Part of the oil floats up and enters the floating oil pipe 113 through the oil overflow hole 114.

[0079] The water body sinks, and under the action of the pressure pump 314, the water body enters the upper drainage pipe 21 and the straight middle pipe 22 from the upper connecting outer pipe 111. The first air pump 37 drives the gas to be transported from the telescopic pipe 36 to the gas cylinder 33, and then is input into the straight middle pipe 22 through the gas cylinder 33. In this process, the control cylinder 313 drives to drive the control bolt 312 to move downward or upward, and the gas cylinder 33 is driven to rotate under the lifting action of the control bolt 312, so as to realize all-round gas delivery.

[0080] The gas in the gas delivery cylinder 33 can fully contact the water in the air flotation impact area 7 to form bubbles in the air flotation impact area 7, and the oil in the straight middle tube 22 adheres to the bubbles and floats up with the bubbles, and enters the upper connecting outer tube 111 from the floating oil vertical pipe 24, and then enters the floating oil pipe 113 or the upper connecting inner tube 112, and the oil is discharged;

[0081] After the initial separation, the water body continues to be transported downward into the upper floating pipe 23, and then enters the lower connecting outer pipe 121 through the triangular pipe 25. The water body settles to the bottom of the lower connecting outer pipe 111. Before entering the lower drainage slit 123, the second air pump 46 drives the external gas to enter the connecting pipe 41, and then enters the ventilation groove 45 through the expansion joint 42, and then enters the lower connecting outer pipe 121 from the transport pipe 44. During the process, the lifting cylinder 410 drives the movable shaft column 48 to move outward, and the fixed ball seat 49 drives the movable groove seat 47 to rotate to one side, and the transport pipe 44 rotates accordingly, and the gas output direction changes accordingly. The gas fully contacts the water that is about to enter the lower drainage slit 123. Under the effect of air flotation, the oil in the lower connecting outer tube 121 is accelerated to float up. The oil passes through the triangular tube 25, the upper floating tube 23, the straight middle tube 22, and the floating oil vertical tube 24 from the lower connecting outer tube 121 to the upper connecting outer tube 111, and then enters the floating oil tube 113 or enters the upper connecting inner tube 112, and the oil is discharged;

[0082] The remaining water enters the lower connecting inner pipe 122 through the lower drainage slit 123 and is discharged.
