[0024] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0025] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the contour of the corresponding component. Furthermore, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] according to Figure 1As shown, an embodiment of the present disclosure provides a complex catalyst preparation device for synthetic oil, which is used to prepare a complex catalyst. The preparation device may include a preparation container 1, a medium input component and a control component. The preparation container 1 is used to provide a reaction site for the reaction medium. The medium input component is used to transport the reaction medium to the preparation container 1. The control component is used to cooperate with the medium input component to control the output of the reaction medium and detect the state in the preparation container 1. The preparation container 1 includes a receiving chamber 120 for filling the reaction medium. The medium input component includes a first conveying component 201 and a second conveying component 202. The first conveying component 201 is used to transport the promoter to the receiving chamber 120, and the second conveying component 202 is used to transport the promoter to the receiving chamber 120. 20 for conveying catalyst, the control component includes a controller, a pressure sensor 213 and a liquid level sensor 214, the controller is respectively connected with the pressure sensor 213, the liquid level sensor 214, the first conveying component 201 and the second conveying component 202 by signal, the pressure sensor 213 is arranged in the preparation container 1, so as to detect the pressure in the containing chamber 120, and control the conveying amount of the promoter through the controller and the first conveying component 201, the liquid level sensor 214 is arranged in the preparation container 1, so as to detect the liquid level in the containing chamber 120, and control the conveying amount of the catalyst through the controller and the second conveying component 202.

[0027] The structure of the preparation container 1 can be adaptively adjusted according to actual conditions, for example, Figure 1 As shown, the preparation container 1 can be a preparation kettle, and the present disclosure does not make any special limitation on this, as long as it can achieve its function.

[0028] Through the above technical solution, the pressure sensor 213 is used to detect the pressure in the accommodating chamber 120, and feeds back the detected pressure value to the controller. The pressure setting value can be set in advance in the controller. For example, when the current pressure value detected is less than the pressure setting value, the controller can control the catalyst to start input by controlling the second conveying component 202; when the current pressure value detected is greater than or equal to the pressure setting value, the controller can control the catalyst to stop input by controlling the second conveying component 202. In addition, the pressure setting value can be a value or a range value. For example, when the pressure value is less than the minimum value, the catalyst input is controlled, and when the pressure value is greater than or equal to the maximum value, the catalyst input is stopped. Similarly, the liquid level sensor 214 is used to detect the liquid level in the accommodating chamber 120, and feeds back the detected liquid level value to the controller. The preset value can be set in advance in the controller. For example, when the current liquid level value detected is less than the preset value, the controller can control the promoter to start input by controlling the first conveying component 201; when the liquid level value detected is greater than or equal to the preset value of the liquid level, the controller can control the promoter to stop input by controlling the first conveying component 201. In addition, the preset value of the liquid level can be a single value or a range value. For example, when the liquid level value is less than the minimum value, the input of the promoter is controlled, and when the liquid level value is greater than or equal to the maximum value, the input of the promoter is stopped. Thus, the pressure and liquid level in the containing chamber 120 can be detected to adjust the delivery amount of the promoter and the catalyst to meet the needs of different process flows.

[0029] In some embodiments, for example, reference Figure 1 As shown, the first delivery assembly 201 may include a promoter delivery pipeline 210 and a first control valve 211 disposed on the promoter delivery pipeline 210, the promoter delivery pipeline 210 is connected to the accommodating chamber 120, and the second delivery assembly 202 may include a catalyst delivery pipeline 220 and a second control valve 212 disposed on the catalyst delivery pipeline 220, the catalyst delivery pipeline 220 is connected to the accommodating chamber 120, and the first control valve 211 and the second control valve 212 are respectively connected to the controller signal. The first control valve 211 and the second control valve 212 are respectively connected to the controller by signal to realize automatic regulation of the delivery amount of the promoter and the catalyst, greatly improving the preparation efficiency of the complex catalyst. It should be noted that in the specific embodiment provided in the present disclosure, the promoter can be n-butanol, and the catalyst can be boron trifluoride. The first control valve 211 and the second control valve 212 can be electric valves / solenoid valves.

[0030] In some embodiments, the first delivery component 201 may further include an accelerant feed tank, which is connected to the accelerant delivery pipeline 210 and is used to store the accelerant to ensure continuous output of the accelerant.

[0031] In some embodiments, the second delivery assembly 202 may further include a catalyst filter, which is disposed on the catalyst delivery pipeline 220 to filter impurities that may be present in the catalyst. In addition, the catalyst delivery pipeline 220 may also be connected to a container for placing the catalyst, which is not specifically limited in the present disclosure.

[0032] In some embodiments, for example, reference Figure 1 As shown, the catalyst delivery pipeline 220 extends to the bottom of the accommodating chamber 120 and is connected to a catalyst distributor 222. The catalyst distributor 222 is used to diffuse the catalyst to increase the reaction area with the promoter. For example, the catalyst distributor 222 can be a porous row pipe type gas distributor or any other suitable form of distributor. The structure of the catalyst distributor 222 can be adaptively adjusted according to actual conditions, for example, it can be a shower head type or a pagoda type.

[0033] In some embodiments, for example, Figure 1 As shown, the complex catalyst preparation device for synthetic oil disclosed in the present invention may also include a cooling component, which may include a cooling pipeline 113, a refrigerant pump 320, a refrigerant input pipeline 301, a refrigerant return pipeline 302 and a third control valve 310. The cooling pipeline 113 is arranged in the accommodating chamber 120, and the inlet of the cooling pipeline 113 is connected to the refrigerant input pipeline 301. The refrigerant input pipeline 301 is used to transport cooling medium into the accommodating chamber 120. The outlet of the cooling pipeline is connected to the refrigerant return pipeline 302. The third control valve 310 and the refrigerant pump 320 are both arranged on the refrigerant input pipeline 301, and the third control valve 310 is located upstream of the refrigerant pump 320 on the refrigerant input pipeline 301. The control component also includes a temperature sensor 215. The temperature sensor 215 and the third control valve 310 are respectively connected to the controller signal. The temperature sensor 215 is used to detect the temperature in the accommodating chamber 120 and control the flow of the cooling medium through the controller and the third control valve 310. The cooling medium may be ice water or refrigerant. The third control valve 310 may be an electric valve / solenoid valve.

[0034] The structure of the cooling assembly can be adaptively adjusted according to actual conditions. For example, the cooling assembly can also include a refrigerating unit and a freezing liquid tank. The freezing liquid tank is connected to the refrigerant input pipeline 301 and the refrigerant return pipeline 302 respectively. The freezing liquid tank is used to store the cooling medium. The freezing liquid tank is configured in the refrigerating unit. The refrigerating unit is used to cool the cooling medium that flows through the cooling pipeline 113 and absorbs heat and heats up. By providing the freezing liquid tank and the refrigerating unit, the cooling medium can be recycled and the temperature in the accommodating cavity 120 can be continuously reduced.

[0035] In some embodiments, for example, reference Figure 1 As shown, the refrigerant input pipeline 301 further includes a first branch 311 and a second branch 312, and the cooling assembly further includes a heat exchange jacket 330, which covers at least a portion of the outer wall surface of the preparation container 1, and the heat exchange jacket 330 is connected to the refrigerant input pipeline 301 through the first branch 311, and the cooling pipeline 113 is connected to the refrigerant input pipeline 301 through the second branch 312. The cooling medium input through the refrigerant input pipeline 301 is divided into the first branch 311 and the second branch 312, and the heat exchange jacket 330 connected to the first branch 311 is used to cool the outside of the preparation container 1, and the cooling pipeline 113 connected to the second branch 312 is used to cool the inside of the preparation container 1 to improve the cooling effect.

[0036] In some embodiments, a fourth control valve 313 may be provided on the first branch 311 to adjust the flow through the first branch 311, and a fifth control valve 314 may be provided on the second branch 312 to adjust the flow through the second branch 312. Thus, the flow of the cooling medium flowing through the first branch 311 and the second branch 312 can be distributed to balance the temperature inside and outside the preparation container 1.

[0037] The fourth control valve 313 and the fifth control valve 314 can be set according to actual application requirements. For example, the fourth control valve 313 and the fifth control valve 314 can be manual control valves or electric valves / solenoid valves. When the fourth control valve 313 and the fifth control valve 314 are electric valves / solenoid valves, the fourth control valve 313 and the fifth control valve 314 can be connected to the controller signal respectively, so that the opening and closing states of the fourth control valve 313 and the fifth control valve 314 can be controlled by the controller.

[0038] In some embodiments, for example, Figure 1As shown, the cooling pipeline 113 can be arranged in a spiral shape in the accommodating chamber 120. The complex catalyst preparation device for synthetic oil disclosed in the present invention can also include a stirring mechanism, which includes a driving member 101, a rotating shaft 111 and a stirring paddle 112. The driving member 101 is connected to the rotating shaft 111 and is located outside the preparation container 1. The driving member 101 is used to drive the rotating shaft 111 to rotate around its own central axis. The rotating shaft 111 extends into the accommodating chamber 120. The stirring paddle 112 is connected to the rotating shaft 111 and is located in the accommodating chamber 120 and in the inner space surrounded by the cooling pipeline 113. The stirring paddle 112 is arranged in the inner space surrounded by the cooling pipeline 113. The stirring paddle 112 is used to stir the reaction medium so that the reaction medium reacts fully. When the reaction medium reacts and releases heat, the spiral arrangement of the cooling pipeline 113 can quickly absorb the heat to achieve a cooling effect.

[0039] The structure of the cooling pipeline 113 disclosed in the present disclosure is only for the purpose of the present disclosure. The structure of the cooling pipeline 113 can be adaptively adjusted according to actual conditions. The present disclosure does not make any special limitation on this, as long as its function can be achieved.

[0040] In some embodiments, for example, reference Figure 1 The complex catalyst preparation device for synthetic oil disclosed in the present invention may also include a medium output assembly, the medium output assembly includes an output pipeline 430, an output valve 410 and a metering pump 420, the output pipeline 430 is connected to the preparation container 1, and the output valve 410 and the metering pump 420 are both arranged on the output pipeline 430. The medium output assembly is used to output the complex catalyst obtained by the reaction of the promoter and the catalyst, the output valve 410 is used to control whether the complex catalyst is output, and the metering pump 420 is used to control the output size of the complex catalyst; when the downstream is an intermittent process, the output valve 410 is opened when necessary to transport the prepared complex catalyst to the downstream reactor. When the downstream is a continuous process, the output valve 410 is set to a normally open state, and the prepared complex catalyst is continuously transported to the downstream reactor. Among them, the reactor can be used for the polymerization reaction of PAO base oil.

[0041] The embodiment of the present disclosure also provides a synthetic oil reaction device, including the above-mentioned complex catalyst preparation device for synthetic oil. The synthetic oil reaction device generally also includes a polymerization reactor, which is connected to the synthetic oil complex catalyst preparation device, so that the complex catalyst prepared by the synthetic oil complex catalyst preparation device can be transported to the polymerization reactor, and a-olefin polymerization reaction is carried out in the polymerization reactor to obtain synthetic oil. The synthetic oil reaction device has all the beneficial effects of the above-mentioned synthetic oil complex catalyst preparation device, and the present disclosure will not repeat them.

[0042] The present disclosure describes the complex catalyst preparation process of the complex catalyst preparation device for synthetic oil by way of example, for example: during preparation, the promoter is first injected into the containing chamber 120, when the liquid level reaches the preset value, the liquid level sensor 214 sends a signal to the controller, and the controller feeds back the signal to the first control valve 211, so that the first control valve 211 is automatically closed and the delivery of the promoter is stopped, at this time, the catalyst is injected into the containing chamber 120, when the pressure value in the containing chamber 120 reaches the preset value, the delivery of the catalyst can be stopped, and the second control valve 212 is automatically closed. When the catalyst and the promoter are complexed, causing the pressure value in the containing chamber 120 to drop to less than the preset value, the second control valve 212 can be opened to input the catalyst, and similarly, when the liquid level drops to less than the preset value, the first control valve 211 can be opened to input the promoter, thereby automatically adjusting the ratio of the catalyst and the promoter, the configuration efficiency of the complex catalyst can be improved, the quality of the complex catalyst can be guaranteed, and the production efficiency can be improved.

[0043] In addition, the complex reaction between the catalyst and the promoter will release heat, causing the temperature in the containing chamber 120 to rise, the solubility of the catalyst to decrease, and the preparation efficiency of the complex catalyst to decrease. At this time, the temperature in the containing chamber 120 is fed back to the controller through the temperature sensor 215. The controller can control the third control valve 310 of the cooling component to transport cooling medium to the containing chamber 120 and the heat exchange jacket 330 to reduce the temperature of the preparation container 1.

In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
