[0040] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] Oil extraction, oil refining and other petrochemical related fields will produce a large amount of oily sludge. If it is discharged directly without treatment, it will have a serious impact on the environment on the one hand, and cause a waste of resources on the other hand. Therefore, achieving the harmlessness and resource utilization of oily sludge is the ultimate goal of current research.

[0042] In the related technology, "thermochemical cleaning technology" is generally used to treat oily sludge. Specifically, a certain proportion of hot water and chemical agents such as surfactants are added to the oily sludge. The properties of the oil / liquid phase and oil / mud phase interfaces in the oily sludge are changed through the rolling, emulsifying, dissolving, and solubilizing effects of the chemical agents. The crude oil is washed and peeled off from the surface of the mud and sand, and then the oily sludge is separated into three phases of oil, water, and mud and sand through sedimentation, centrifugation and other processes.

[0043] However, with the large-scale implementation of ASP flooding technology in oil fields, the sludge produced forms a multiphase emulsified system of polymer, sludge, crude oil, etc., which makes it more difficult to clean and separate the oily sludge. Therefore, there is an urgent need for a device that can achieve efficient treatment of oily sludge.

[0044] In order to overcome the defects in the prior art, the present application provides a separation device, including a reaction tank, an agitator, a heat management pipeline and an ultrasonic component. Among them, the reaction tank has a containing chamber, the containing chamber is used to contain the mixture to be separated, the agitator is located in the containing chamber to stir the mixture, the heat management pipeline is partially located in the containing chamber, the heat transfer medium flows in the heat management pipeline, and the mixture is heated by the part of the heat management pipeline in the containing chamber, and the transducer of the ultrasonic component is located in the containing chamber, and emits ultrasonic waves relative to the mixture in the containing chamber. In this way, during the process of stirring the mixture by the agitator, the solid and liquid in the mixture are initially separated, the heat transfer medium heats the mixture, and further promotes the separation degree between the solid and liquid in the mixture, and the transducer emits ultrasonic waves and acts on the mixture to improve the separation effect and separation efficiency of the solid and liquid in the mixture. Such a separation device realizes the efficient separation of the mixture, avoids the pollution of the environment by the oily sludge, and makes the discharged oily sludge meet the environmental protection standards.

[0045] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0046] Figure 1 A schematic diagram of a separation device provided in an embodiment of the present application. Figure 2 A top view of the collecting tank of the separation device provided in the embodiment of the present application. Figure 1-Figure 2 As shown, a separation device 100 includes: a reaction tank 110, an agitator 120, a thermal management pipeline 130 and an ultrasonic component 140.

[0047] The reaction tank 110 has a containing chamber 111, and the containing chamber 111 is used to contain the mixture to be separated.

[0048] The stirrer 120 is located in the accommodating chamber 111 , and the stirrer 120 is used for stirring the mixture.

[0049] A portion of the heat management pipeline 130 is located in the accommodating chamber 111 . The heat transfer medium flows in the heat management pipeline 130 and heats the mixture through the portion of the heat management pipeline 130 located in the accommodating chamber 111 .

[0050] The ultrasonic component 140 includes a transducer 141 . The transducer 141 is located in the accommodating cavity 111 and emits ultrasonic waves toward the mixture.

[0051] According to the separation device 100 provided in this embodiment, the stirrer 120 is located in the accommodating chamber 111, and the stirrer 120 rotates and stirs the mixture, which can separate the liquid and solid in the mixture. Furthermore, the heat management pipeline 130 is located in the accommodating chamber 111, and the mixture is heated by the heat-conducting medium flowing in the heat management pipeline 130 to promote the separation of the solid and liquid in the mixture. The transducer 141 emits ultrasonic waves to the mixture in the accommodating chamber 111, and the cavitation effect generated by the ultrasonic waves is used to separate the liquid in the mixture from the solid surface. In this way, through the mutual cooperation and interaction between the various components, the separation degree and separation efficiency of the liquid and solid in the mixture are improved, the oily sludge is prevented from polluting the environment, and the discharged oily sludge meets the environmental protection standards.

[0052] It should be noted that the mixture in this embodiment is a mixture of oily sludge and an activator. The activator acts on the surface of the oily sludge to achieve demulsification of the oily sludge to ensure that the liquid oil in the oily sludge is separated from the solid mud.

[0053] Exemplarily, the reaction tank 110 in this embodiment can be of various structures, such as a square columnar structure, a round columnar structure, etc., which is not specifically limited in this section. The reaction tank 110 has a receiving chamber 111, and the mixture to be separated can be introduced into the receiving chamber 111. Specifically, the oily sludge and the active agent can be introduced into the receiving chamber 111 of the reaction tank 110 in a certain proportion, or the oily sludge and the active agent can be mixed uniformly in advance in a certain proportion and then introduced into the receiving chamber 111 of the reaction tank 110.

[0054] The agitator 120 is located in the accommodating chamber 111, and the agitator 120 rotates in the accommodating chamber 111 to stir the mixture so that the mixture is evenly mixed in the accommodating chamber 111. It can be understood that the mixture is put into the reaction tank 110, and the agitator 120 rotates to promote the uniform mixing of the oily sludge and the active agent in the mixture, and the active agent and the oily sludge are fully in contact, so as to achieve the demulsification and separation of the oil on the surface of the oily sludge, and the separation of the liquid and the solid in the mixture is achieved under the action of the agitator 120. The agitator 120 in this embodiment may have a spiral blade structure, and the spiral blade rotates to drive the mixture to move in the accommodating chamber 111, so that the mixture is mixed more evenly.

[0055] Optionally, the rotation speed of the agitator 120 may be 60-100 r / min.

[0056] Furthermore, a portion of the heat management pipeline 130 is located in the accommodating chamber 111, and a heat transfer medium flows in the heat management pipeline 130, and heats the mixture through the portion of the heat management pipeline 130 located in the accommodating chamber 111. Specifically, the heat transfer medium may be water, which is heated to form hot water, and the hot water flows in the heat management pipeline 130 to control the temperature in the reaction tank 110 and heat the mixture, thereby promoting the separation of solids and liquids in the mixture.

[0057] The temperature of the heat-conducting medium in this embodiment can be controlled above 80°C. For example, the temperature of the heat-conducting medium partially flowing in the accommodating chamber 111 through the thermal management pipeline 130 is 90°C. This can maintain the temperature of the mixture in the reaction tank 110 at 75°C-85°C to promote the separation of solids and liquids in the mixture.

[0058] In order to improve the separation degree and separation efficiency of solids and liquids in the mixture, the transducer 141 of the ultrasonic component 140 is located in the accommodating chamber 111. The transducer 141 emits ultrasonic waves to the mixture in the accommodating chamber 111. The ultrasonic waves act on the mixture and produce cavitation effect on the mixture. After the liquid in the mixture is activated by the active agent, it is analyzed and separated from the solid surface to promote the separation of the mixture, improve the separation degree and separation efficiency, and the separation effect of the mixture.

[0059] It should be noted that the working power of the transducer 141 in this embodiment is 2.4 kW, and the frequency of the ultrasonic wave emitted by the transducer 141 is 25 kHz.

[0060] Possibly, the height of the heat management pipeline 130 located in the accommodating chamber 111 is higher than the transducer 141 , and the agitator 120 is located on a side close to the bottom end of the reaction tank 110 .

[0061] The mixture enters the containing cavity 111 of the reaction tank 110 and is deposited on the inner bottom of the reaction tank 110. The agitator 120 is located on one side close to the bottom end of the reaction tank 110, which can ensure better contact between the agitator 120 and the mixture, so as to ensure that the agitator 120 mixes the mixture evenly. At the same time, the separation of liquid and solid in the mixture is promoted during the stirring process.

[0062] It is not difficult to understand that the height of the thermal management pipeline 130 located in the accommodating cavity 111 is higher than the transducer 141, that is, the transducer 141 can be located on the side of the reaction tank 110 close to the bottom to ensure that the effective contact between the mixture and the ultrasonic wave emitted by the transducer 141 is increased, the cavitation effect of the ultrasonic wave is more intense and uniform, and the separation of liquid and solid in the mixture is promoted.

[0063] In a specific embodiment, there are multiple transducers 141, which are sequentially distributed around the axis of the reaction tank 110 and connected to the inner wall of the reaction tank 110. The multiple transducers 141 emit ultrasonic waves from different angles, reducing the contact dead angle between the ultrasonic waves and the mixture, and the mixture and the ultrasonic waves are evenly distributed and contacted in the accommodating chamber 111, which helps the cavitation effect of the ultrasonic waves on the mixture, promotes the separation of the mixture, and improves the separation degree and separation effect of the mixture.

[0064] For example, there may be three transducers 141, which are distributed around the axis of the reaction tank 110, and the angle between adjacent transducers 141 is 120°. In this way, the three transducers 141 emit ultrasonic waves from different angles, and the ultrasonic waves are evenly distributed in the accommodating cavity 111, which also increases the effective contact area of ​​the ultrasonic waves on the mixture, and promotes the separation of the mixture under the stirring action of the stirrer 120.

[0065] Furthermore, the ultrasonic component 140 further includes an ultrasonic generator 142, which is disposed outside the reaction tank 110 and is electrically connected to the transducer 141. The ultrasonic generator 142 and the transducer 141 are disposed one-to-one and electrically connected to the transducer 141, and the ultrasonic generator 142 can convert electrical energy into a high-frequency alternating current signal that matches the transducer 141, so as to emit ultrasonic waves through the transducer 141 and act on the mixture.

[0066] It is understandable that the stirrer 120 is located in the accommodating chamber 111, and the stirrer 120 rotates in the accommodating chamber 111, and the stirrer 120 acts on the mixture to mix the mixture evenly. There are many ways to drive the stirrer 120. As a possible embodiment, the separation device 100 also includes a motor 150, which is disposed at the top of the reaction tank 110, and the motor 150 is connected to the stirrer 120, and the motor 150 drives the stirrer 120 to rotate.

[0067] The motor 150 is disposed at the top of the reaction tank 110. The motor 150 and the reaction tank 110 are relatively fixedly connected. The output shaft 151 of the motor 150 is partially located in the accommodating cavity 111 of the reaction tank 110. The output shaft 151 is connected to the stirrer 120 on one side facing the bottom of the reaction tank 110. After the motor 150 is started, the motor 150 drives the stirrer 120 to rotate around the output shaft 151 of the motor 150 to stir the mixture. In this embodiment, the output speed of the motor 150 is adjustable, and the speed of the stirrer 120 can be changed by adjusting the output speed of the motor 150.

[0068] In some embodiments, the reaction tank 110 has an inlet 112, a first outlet 113 and a second outlet 114. The inlet 112 is connected to the accommodating chamber 111, and the height of the inlet 112 is higher than the portion of the thermal management pipeline 130 located in the accommodating chamber 111; the first outlet 113 is connected to the accommodating chamber 111, and the height of the first outlet 113 is higher than the inlet 112; the second outlet 114 is located at the bottom end of the reaction tank 110 and is connected to the accommodating chamber 111.

[0069] It is not difficult to understand that the reaction tank 110 has an inlet 112, and the inlet 112 is connected to the accommodating chamber 111 so that the mixture can be introduced into the accommodating chamber 111 through the inlet 112. The height of the inlet 112 is higher than the part of the thermal management pipeline 130 located in the accommodating chamber 111. When the mixture enters the accommodating chamber 111, it can be heated by this part of the thermal management pipeline 130 in advance to promote the interaction between the active agent and the oily sludge in the mixture. At the same time, after the solid and liquid in the mixture are separated, the solid is deposited at the bottom of the reaction tank 110, and the liquid rises to the upper layer of the solid. The liquid is relatively close to the thermal management pipeline 130 located in the accommodating chamber 111, and the heat transfer medium is thermally connected to the liquid through the thermal management pipeline 130 to improve the fluidity of the liquid so that the liquid can be discharged from the first outlet 113.

[0070] Furthermore, in this embodiment, the first outlet 113 is connected to the accommodating chamber 111, and the separated liquid in the mixture is discharged from the reaction tank 110 through the first outlet 113. The height of the first outlet 113 is higher than the inlet 112. In this way, the mixture can be introduced into the accommodating chamber 111 through the inlet 112, and the liquid level can be adjusted. When the liquid level is higher than the first outlet 113, the liquid overflows from the first outlet 113.

[0071] The reaction tank 110 also has a second outlet 114, which is located at the bottom of the reaction tank 110 and communicates with the accommodating chamber 111 of the reaction tank 110. After the liquid in the reaction tank 110 is discharged, the remaining solid in the reaction tank 110 can be discharged from the second outlet 114 at the bottom of the reaction tank 110.

[0072] In order to facilitate the collection of liquid, the inner wall of the reaction tank 110 is provided with a collecting groove 115, the height of which is higher than the inlet 112, and the collecting groove 115 is connected to the accommodating cavity 111 and the first outlet 113; the groove wall of the collecting groove 115 is inclined relative to the reaction tank 110 toward the first outlet 113. The liquid level is adjusted to be higher than the collecting groove 115, and the liquid flows into the collecting groove 115 along the groove wall of the collecting groove 115, and is finally discharged through the first outlet 113.

[0073] In this embodiment, the collecting groove 115 is an annular groove, the top of the collecting groove 115 has an opening, and is connected to the accommodating chamber 111 of the reaction tank 110, and the bottom of the collecting groove 115 is connected to the first outlet 113. In this way, when the liquid level is higher than the top of the collecting groove 115, the liquid level flows into the collecting groove 115 and is finally discharged from the reaction tank 110 through the first outlet 113.

[0074] In order to improve the fluidity of the liquid in the collecting tank 115 and prevent the liquid from being stored in the collecting tank 115, the bottom wall of the collecting tank 115 in this embodiment is inclined relative to the first outlet 113. It can be understood that the bottom wall of the collecting tank 115 forms an angle between the plane on which it sits and the horizontal plane, and the angle is 5°-10°, that is, the slope of the bottom wall of the collecting tank 115 is 5‰.

[0075] In addition, in some embodiments, the radial dimension of the inner wall of the reaction tank 110 near the second outlet 114 gradually decreases along the direction from the first outlet 113 to the second outlet 114. In this way, part of the inner wall of the reaction tank 110 forms a conical structure, and the reaction tank 110 can accommodate more mixture, thereby improving the processing efficiency of the separation device 100 for the mixture. Such a reaction tank 110 is easy to discharge the solid inside from the second outlet 114 at the bottom.

[0076] Based on the above embodiment, the separation device 100 further includes a feed pipe 160 , a first discharge pipe 170 and a second discharge pipe 180 . The feed pipe 160 is connected to the inlet 112 , the first discharge pipe 170 is connected to the first outlet 113 , and the second discharge pipe 180 is connected to the second outlet 114 .

[0077] The feed pipe 160 is connected to the inlet 112 of the reaction tank 110 so as to pass the mixture into the reaction tank 110 through the feed pipe 160. It should be noted that the mixture in this part can be a pre-prepared mixture of oily sludge and active agent, or the oily sludge and active agent can be separated and passed into the reaction tank 110 through the feed pipe 160.

[0078] The first discharge pipe 170 is connected to the first outlet 113, and the liquid separated from the mixture enters the first discharge pipe 170 along the first outlet 113 and is discharged from the reaction tank 110. The end of the first discharge pipe 170 away from the first outlet 113 can be connected to a collection device to collect the liquid. That is, the oil separated from the oily sludge flows through the first discharge pipe 170 to the collection device to be stored for other uses.

[0079] The second discharge pipe 180 is connected to the second outlet 114, and the solids deposited at the bottom of the reaction tank 110 enter the second discharge pipe 180 along the second outlet 114 and are discharged from the reaction tank 110. It can be understood that the mixture treated by the separation device 100, i.e., the oily sludge, has met the discharge standard and can be directly discharged.

[0080] Possibly, the separation device 100 further includes a static mixer 190 , which is connected between the feed pipe 160 and the reaction tank 110 ; the feed pipe 160 includes a first feed pipe 160 a and a second feed pipe 160 b , which are connected to the static mixer 190 in parallel.

[0081] The static mixer 190 is connected between the feed pipe 160 and the reaction tank 110. The mixture is passed to the static mixer 190 through the feed pipe 160. The mixture is stirred, dispersed and mixed in the static mixer 190 so that the oily sludge and the active agent in the mixture are evenly mixed. The mixture is then passed into the containing chamber 111 of the reaction tank 110 to improve the separation efficiency of the mixture in the containing chamber 111.

[0082] Exemplarily, the feed pipe 160 has a first feed pipe 160a and a second feed pipe 160b, and the first feed pipe 160a and the second feed pipe 160b are connected in parallel to the static mixer 190. The first feed pipe 160a delivers the oily sludge to the static mixer 190, and the second feed pipe 160b delivers the active agent to the static mixer 190. In this way, the active agent and the oily sludge are pre-mixed and prepared in the static mixer 190.

[0083] In a specific working process of the separation device 100: the mixture mixed by the static mixer 190 is passed into the containing chamber 111 of the reaction tank 110; the agitator 120 is turned on, and the speed of the agitator 120 is controlled to be 60r / min; the transducer 141 is turned on at the same time, and the transducer 141 emits ultrasonic waves with a frequency of 25kHz into the containing chamber 111; hot water with a temperature of 90°C is continuously passed into the thermal management pipeline 130, and the temperature of the mixture in the reaction tank 110 is maintained at 75°C to 85°C; after the mixture in the reaction tank 110 continues to react for 40 minutes, the agitator 120 and the transducer 141 stop working; and stand for 15 minutes. In this way, the solid and liquid in the reaction tank 110 form layers, and the liquid (oil) separated from the upper layer of the reaction tank 110 is discharged and recovered through the collecting tank 115 and the first discharge pipe 170; the solid (mud) deposited at the bottom of the reaction tank 110 is discharged through the second outlet 114 and the second discharge pipe 180.

[0084] In addition, the researchers sampled and tested the oily sludge discharged from the separation device 100 and found that the content of petroleum in the oily sludge treated by the separation device 100 provided in this embodiment was 1%-1.2%. Therefore, the separation device 100 provided in this embodiment achieves deep separation of the oily sludge and improves the separation effect. The treated oily sludge meets the discharge standard and does not pollute the environment.

[0085] The separation device 100 provided in this embodiment includes a reaction tank 110, an agitator 120, a heat management pipeline 130 and an ultrasonic component 140. The reaction tank 110 has a receiving chamber 111, and the receiving chamber 111 is used to receive the mixture to be separated. The agitator 120 is located in the receiving chamber 111, and the agitator 120 is used to stir the mixture. The heat management pipeline 130 is partially located in the receiving chamber 111, and the heat-conducting medium flows in the heat management pipeline 130, and the mixture is heated by the part of the heat management pipeline 130 located in the receiving chamber 111. The ultrasonic component 140 includes a transducer 141, which is located in the receiving chamber 111 and emits ultrasonic waves to the mixture. Through such a structural arrangement, efficient treatment of oily sludge is achieved, and the separation degree of oil and mud in the oily sludge is improved.
