Description

Technical Field

[0001] The present invention relates to the technical field of oily sludge treatment, and more specifically, to an automatic separation type oily sludge treatment device. Background Art

[0002] The source of oily sludge in oil fields is mainly the oily sludge generated during crude oil extraction and gathering and transportation. In addition to crude oil, these oily sludges also contain formation sediment carried in the produced fluid, oily scum formed during the sewage treatment process of oilfield sewage treatment plants, corrosion products of pipelines and storage tanks, as well as colloids, asphaltene and a certain amount of water.

[0003] At present, the automatic separation of oily sludge mainly uses a horizontal screw centrifuge to separate the oil from the oily sludge. The horizontal screw centrifuge is mainly composed of a high-speed drum, a screw conveyor with a hollow shaft that has the same rotation direction as the drum and a slightly lower or higher speed than the drum, and a differential. When the suspension to be separated is sent into the drum by the spiral core tube, it is immediately thrown into the drum cavity under the centrifugal force generated by the high-speed rotation. Under the strong centrifugal force generated by the high-speed rotating drum, the mud and water layer is pushed by the screw conveyor and gradually moves to one end of the drum and is discharged and collected in the mud and water tank, while the oil is discharged through the other end of the drum and collected in the oil tank.

[0004] However, in arid or dry environments, the water in oily sludge is easy to evaporate, resulting in a decrease in water content. The sludge with low water content has higher viscosity and poorer fluidity, which will increase the flow resistance in pipelines and equipment during sludge extraction and separation, affecting the smoothness of the feed. In addition, in sludge with low water content, the interface between oil and water is not obvious, and the separation difficulty increases, resulting in a decrease in the separation efficiency of the horizontal screw centrifuge, resulting in the ineffective separation of oil and water, affecting the purity and recovery rate of the final separated oil. Summary of the invention

DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Refer to the instruction manual Figures 1 to 3 , an automated separation type oily sludge treatment equipment, comprising: a separation mechanism 1, the separation mechanism 1 comprising a pretreatment tank 11, a horizontal screw centrifuge 12, a mud water tank 13 and an oil tank 14;

[0037] The pretreatment tank 11 is provided with a water replenishing mechanism 2, which includes a water adding component 21 and a stirring component 22. The stirring component 22 includes an inner cylinder 221 and a plurality of stirring blades 224, and the plurality of stirring blades 224 can orbit around the vertical center line of the inner cylinder 221. The inner cylinder 221 is used to hold the oily sludge, the water adding component 21 is used to add water to the oily sludge, and the stirring blades 224 are used to stir the oily sludge after adding water to increase the water content of the oily sludge.

[0038] The pretreatment tank 11 is also provided with a feed assembly 3 for conveying the oily sludge into the decanter centrifuge 12 , separating the oily sludge by the decanter centrifuge 12 , and collecting the separated mud water and oil into the mud water tank 13 and the oil tank 14 , respectively.

[0039] It should be noted that the water adding component 21 can use a water pump to add water to the oily sludge, and the stirring component 22 can drive the stirring blades 224 through a motor to stir and mix the oily sludge after the water is added to increase the water content of the oily sludge. The feeding component 3 can be an extraction pump and a material pipe. By extending the material pipe into the inner cylinder 221 and under the action of the extraction pump, the oily sludge is transported to the horizontal screw centrifuge 12 for separation.

[0040] The specific implementation scenario is as follows: first, add oily sludge into the inner cylinder 221 in the pretreatment tank 11. When the water content of the oily sludge is low, water can be added to the inner cylinder 221 through a water pump, and at the same time, the motor drives the stirring blade 224 to stir the oily sludge after adding water, so that the oily sludge and water are fully mixed to increase the water content of the oily sludge. By increasing the water content of the low-water-content oily sludge, the viscosity of the oily sludge can be significantly reduced, and its fluidity can be improved, making it easier to pass through pipelines and equipment, and the interface between oil and water becomes clearer, which helps the horizontal screw centrifuge 12 to separate more effectively, thereby improving the purity and recovery rate of the finally separated oil.

[0041] For further information, please refer to the attached manual. Figure 2The water adding assembly 21 includes a water pump 211, which is installed on the pretreatment tank 11. The water pump 211 is connected with a water inlet pipe 212 and a water outlet pipe 213. The water outlet end of the water outlet pipe 213 extends into the pretreatment tank 11, and the water outlet end of the water outlet pipe 213 is located above the inner cylinder 221.

[0042] It should be noted that water is pumped through the water inlet pipe 212 of the water pump 211 and discharged through the water outlet pipe 213 to add water to the oily sludge in the inner tube 221, which can conveniently add water to increase the water content of the oily sludge with low water content.

[0043] For further information, please refer to the attached manual. Figure 2 The stirring assembly 22 also includes a driving member 222 , the output end of the driving member 222 is connected to a vertical shaft 223 , the bottom end of the vertical shaft 223 extends into the inner cylinder 221 , and a plurality of stirring blades 224 are fixedly arranged on the vertical shaft 223 .

[0044] It should be noted that the driving member 222 is a motor, and the motor drives the vertical shaft 223 to drive a plurality of stirring blades 224 to stir the oily sludge after the water is added, so that the oily sludge can be fully mixed with water to increase the water content of the oily sludge. Through uniform stirring, the problem of high water content in some parts of the oily sludge and low water content in other parts can be avoided.

[0045] In the above technical scheme, the water replenishing mechanism 2 is used to replenish water to the oily sludge with low water content to increase the water content, so as to solve the problem that in the separation process of the oily sludge with low water content, the interface between oil and water is not obvious in the sludge with low water content, the separation difficulty is increased, and the separation efficiency of the horizontal screw centrifuge 12 is reduced, resulting in the ineffective separation of oil and water, affecting the purity and recovery rate of the finally separated oil. However, in the rainy season or in areas with high groundwater levels, the mined oily sludge usually has a high water content. When the oily sludge with high water content is separated by the horizontal screw centrifuge 12, the high water content of the oily sludge will increase the fluidity of the oily sludge, so that the density difference between the oil, water and solid phases is reduced, thereby increasing the difficulty of effectively separating the three phases of oil, water and solid phases. In the centrifugal separation process, it will lead to poor separation effect and reduced separation efficiency. For this reason, the present invention proposes a dehydration mechanism 4, which can perform dehydration pretreatment on the oily sludge with high water content. For details, refer to the attached figure of the specification. Figure 4 A dehydration mechanism 4 is arranged in the pretreatment tank 11, and the dehydration mechanism 4 includes a power component 41. The output end of the power component 41 is connected to a connecting shaft 42, and the connecting shaft 42 is fixedly arranged at the bottom of the inner cylinder 221. A plurality of through holes 2211 are opened on the inner cylinder 221, and the through holes 2211 are used to discharge water from the inner cylinder 221 during dehydration.

[0046] It should be noted that the power component 41 is a motor, and the motor drives the connecting shaft 42 to drive the inner cylinder 221 to rotate, so that while the inner cylinder 221 rotates, the oily sludge with high water content in the inner cylinder 221 is dehydrated under the action of centrifugal force, and the dehydrated water can be discharged from the inner cylinder 221 through the through hole 2211.

[0047] In the above technical scheme, the water replenishing mechanism 2 can be used to replenish water to increase the water content of the oily sludge with low water content, and the dehydrating mechanism 4 can be used to dehydrate the oily sludge with high water content to reduce the water content. However, in order to facilitate the dehydration of the oily sludge with high water content by opening the through hole 2211 on the inner cylinder 221, when it is necessary to replenish water to increase the water content of the oily sludge with low water content, the water added to the inner cylinder 221 is easy to flow out from the through hole 2211, thereby causing the oily sludge with low water content to be unable to be increased to a sufficient water content for separation. For this reason, the present invention proposes an anti-seepage mechanism, which is used to prevent water from flowing out of the inner cylinder 221 from the through hole 2211 when water is added to the inner cylinder 221. For details, refer to the attached manual. Figure 5 and Figure 6 The anti-seepage mechanism is an anti-seepage component 5, which includes an outer cylinder 51, which is rotatably arranged on the outer side of the connecting shaft 42, and the inner wall of the outer cylinder 51 is in sliding contact with the outer wall of the inner cylinder 221. The outer cylinder 51 is provided with a plurality of side holes 511, and the plurality of side holes 511 are matched with the corresponding through holes 2211. A rotation drive component 52 is arranged in the outer cylinder 51, and the rotation drive component 52 includes a power component 2 521, which is installed on the inner wall of the outer cylinder 51, and a driving gear 1 522 is installed at the output end of the power component 2 521, and a gear 523 is fixedly arranged on the outer side of the connecting shaft 42, and the driving gear 1 522 is meshed with the driven gear 523.

[0048] It should be noted that the power component 2 521 is a motor. When it is necessary to dehydrate the oily sludge with a high water content, the motor can be used to drive the driving gear 1 522 to rotate, so that the driving gear 1 522 can roll around the gear 523, thereby rotating the outer cylinder 51 and connecting the side hole 511 on the outer cylinder 51 with the corresponding through hole 2211. At this time, water can be discharged through the through hole 2211 and the side hole 511 during dehydration. When it is necessary to replenish water for the oily sludge with a low water content, the motor can be used to drive the outer cylinder 51 to rotate, so that the outer cylinder 51 blocks the through hole 2211 to prevent water from flowing out of the through hole 2211 when adding water. This can solve the problem that when replenishing water for the oily sludge with a low water content, water flows out of the through hole 2211, causing the oily sludge with a low water content to be unable to be increased to a sufficient water content for separation.

[0049] In the above technical solution, although the through hole 2211 is shielded by the outer cylinder 51 to prevent water from flowing out of the through hole 2211, when the oily sludge with low water content is replenished with water to increase the water content, the oily sludge is easy to enter the through hole 2211 during the stirring process of the oily sludge after adding water. In the case of long-term use, it is easy to cause the through hole 2211 to be blocked, and then when the oily sludge with high water content is dehydrated, its dehydration efficiency is affected. For this reason, the present invention proposes an anti-seepage component 26, specifically, refer to the attached description of the specification. Figures 7 to 11 The anti-seepage component 2 6 includes a plurality of side strips 61, which are evenly distributed in the circumferential direction of the inner cylinder 221, and the plurality of side strips 61 can move synchronously in the direction close to or away from the center of the inner cylinder 221, and a plurality of blocking rods 611 are fixedly arranged on the plurality of side strips 61, and the plurality of blocking rods 611 are inserted into the corresponding through holes 2211. The anti-seepage component 2 6 also includes a bottom ring 62, which is fixedly arranged at the bottom of the inner cylinder 221, and the plurality of side strips 61 are slidably arranged on the bottom ring 62, and a rotation drive component is arranged in the bottom ring 62. Second 63, the rotation drive component second 63 includes a power component three 631, the output end of the power component three 631 is connected to the driving gear two 632, a disk 633 is rotatably provided on the connecting shaft 42, a gear ring 634 is fixedly provided on the disk 633, the driving gear two 632 is meshed with the gear ring 634, a guide groove 6331 is opened on the disk 633, a circular shaft 64 is fixedly provided at the bottom of several side strips 61, several circular shafts 64 are in sliding contact with the inner wall of the guide groove 6331, and elastic members 65 are provided at the bottom of several side strips 61.

[0050] It should be noted that the power component 3 631 is a motor, and the guide groove 6331 is as follows Fig.11 The elastic member 65 is a spring. Fig.10As shown, in this state, the spring is in a stretched state. When it is necessary to dehydrate the oily sludge with high water content to reduce the water content, the motor can be used to drive the active gear 2 632 to rotate, and the gear ring 634 can be used to drive the disc 633 to rotate. Therefore, during the rotation of the disc 633, the guide groove 6331 cooperates with the circular shaft 64, and under the action of the elastic deformation of the spring, the side bars 61 can be synchronously moved away from the center of the inner cylinder 221, so that the blocking rods 611 can slide out of the corresponding through holes 2211, and then the oily sludge with high water content can be dehydrated by the dehydration mechanism 4. Dehydration reduces the water content. When it is necessary to replenish water to increase the water content of the oily sludge with low water content, the disc 633 can be driven to rotate by a motor, and the several side strips 61 can be synchronously moved in the direction close to the center of the inner cylinder 221, so that the several blocking rods 611 can be inserted into the corresponding through holes 2211, thereby preventing the oily sludge from entering the through holes 2211 and clogging the through holes 2211 when replenishing water to increase the water content of the oily sludge with low water content, and the oily sludge that enters the through holes 2211 during dehydration can also be pushed into the inner cylinder 221, which can further avoid the problem of clogging the through holes 2211.

[0051] In the above technical solution, the dehydration mechanism 4 uses centrifugal dehydration to dehydrate the oily sludge with high water content. However, during the dehydration process, the oil and water in the oily sludge will be removed together. When the oil in the oily sludge is removed together, the yield of the separated oil will be reduced. Therefore, the present invention proposes a recovery mechanism 7 for recovering and utilizing the oil and water discharged during dehydration. For details, refer to the attached manual. Fig.12 A recovery mechanism 7 is provided at the water inlet end of the water inlet pipe 212, and the recovery mechanism 7 includes a three-way pipe 71. The three-way pipe 71 is connected to the water inlet end of the water inlet pipe 212. The three-way pipe 71 is also connected to a pumping pipe 72 and a recovery pipe 73. The water inlet end of the recovery pipe 73 extends into the pretreatment tank 11, and valves 74 are provided on the pumping pipe 72 and the recovery pipe 73.

[0052] It should be noted that the water discharged together with the dehydration mechanism 4 will flow into the pretreatment tank 11 through the through hole 2211. When it is necessary to replenish the oily sludge with low water content, the valve 74 of the recovery pipe 73 can be opened, and the valve 74 on the pumping pipe 72 can be closed. When replenishing water, the oil and water discharged when the oily sludge with high water content is dehydrated can be extracted, and the oil and water can be added to the oily sludge with low water content for replenishment, so that the oil and water discharged during the dehydration of the dehydration mechanism 4 can be recycled, thereby avoiding waste of oil.

[0053] For further information, please refer to the attached manual. Fig.13The feed assembly 3 includes a feed pipe 31, the feed end of the feed pipe 31 extends into the pretreatment tank 11, and the discharge end of the feed pipe 31 is connected to the horizontal screw centrifuge 12, a telescopic tube 32 is provided in the middle of the feed pipe 31, and a driving member 33 is provided on the top of the pretreatment tank 11, and the output end of the driving member 33 is connected to the bottom end of the feed pipe 31, and the driving member 33 is used to drive the bottom end of the feed pipe 31 to extend into the inner cylinder 221.

[0054] It should be noted that the driving member 233 is a cylinder. When dehydrating the oily sludge with high water content or replenishing the oily sludge with low water content, since the oily sludge is located in the inner cylinder 221, if the bottom end of the feed pipe 31 is directly fully inserted into the inner cylinder 221, it is easy for the existence of the feed pipe 31 to interfere with the movement of the oily sludge in the inner cylinder 221, and it is easy to cause damage to the feed pipe 31 during the dehydration or replenishing process. For this reason, after dehydrating the oily sludge with high water content or replenishing the oily sludge with low water content, when it is necessary to extract the oily sludge for separation, the feed pipe 31 can be driven by the cylinder to gradually extend into the inner cylinder 221, so that the feed pipe 31 can be gradually extended into the feed pipe 31 to extract the oily sludge when the oily sludge is in a static state.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
