Abstract
Description
Technical Field
[0001] The present application relates to the technical field of chemical equipment, and in particular to a precise dripping device for C5 and maleic anhydride solution. Background Art
[0002] C5, also known as C5 or pentane, has the chemical formula C5H12 and is the fifth member of the alkanes. Maleic anhydride is an important organic chemical raw material. Its chemical name is maleic anhydride, also known as maleic anhydride or dehydrated malic anhydride.
[0003] C5 and maleic anhydride solution need to be injected into the tower reactor in proportion for processing reaction. The accuracy of the injection amount of C5 and maleic anhydride solution will affect the subsequent reaction quality. Therefore, the injection amount of C5 and maleic anhydride needs to be precisely controlled. Moreover, if C5 and maleic anhydride solution are directly injected into the tower reactor, it will easily lead to uneven mixing of the two, reduce the reaction efficiency and affect the reaction quality. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a precise dripping device for C5 and maleic anhydride solution, which has the advantages of being able to accurately control the dripping injection amount of C5 and maleic anhydride solution, and being able to mix and stir the injected C5 and maleic anhydride solution, thereby ensuring the quality of subsequent reaction operations and improving the reaction operation efficiency. It solves the problem that C5 and maleic anhydride solution need to be injected into a tower reactor in proportion for processing reaction, and the accuracy of the injection amount of C5 and maleic anhydride solution will affect the subsequent reaction quality. Therefore, it is necessary to accurately control the injection dripping amount of C5 and maleic anhydride. Moreover, if the C5 and maleic anhydride solution are directly injected into the tower reactor, it will easily lead to uneven mixing of the two, reduce the reaction efficiency, and affect the reaction quality.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a precise dripping device for C5 and maleic anhydride solution, comprising a tower reactor, an agitator being provided above the tower reactor, two infusion tubes being fixedly connected inside the agitator, one of the infusion tubes being provided with a maleic anhydride container at the top, and the other of the infusion tubes being provided with a C5 container at the top, each of the infusion tubes being provided with a first solenoid valve at the top, and each of the infusion tubes being provided with a flow meter on the outer circumference, the flow meter being electrically connected to the first solenoid valve, a motor being provided at the top of the agitator, a stirring shaft being rotatably connected to the bottom of the motor, and stirring blades being provided on the outer circumference of the stirring shaft being arranged at equal intervals.
[0006] Through the above scheme, since the accuracy of the injection amount of C5 and maleic anhydride solution will affect the subsequent reaction quality, it is necessary to accurately control the injection amount of C5 and maleic anhydride. Moreover, if the C5 and maleic anhydride solution are directly injected into the tower reactor, it is easy to cause uneven mixing of the two, reduce the reaction efficiency, and affect the reaction quality. By arranging a first solenoid valve and a flow meter on the outer circumferential surface of the infusion tube, and electrically connecting the flow meter and the first solenoid valve, the injection amount of C5 or maleic anhydride solution can be accurately controlled to ensure the quality of subsequent reaction operations. By arranging a stirrer at the output end of the two infusion tubes, the C5 and maleic anhydride solutions can be evenly mixed, thereby improving the efficiency of subsequent reaction operations.
[0007] Furthermore, a heating device is provided at the bottom of the maleic anhydride container, and the upper surface of the heating device is fixedly connected with equidistantly arranged heating rods, and the outer circumferential surfaces of the heating rods are fixedly plugged into the interior of the maleic anhydride container.
[0008] By adopting the above scheme, the maleic anhydride solution in the maleic anhydride container is heated to avoid crystallization of the maleic anhydride solution due to low temperature, which would affect the dropwise addition of the maleic anhydride solution.
[0009] Furthermore, a temperature sensor is provided on the front of the maleic anhydride container, the temperature sensor is electrically connected to the heating device, and a display screen is provided on the front of the temperature sensor.
[0010] Through the above scheme, the temperature sensor can detect the temperature of the maleic anhydride solution in the maleic anhydride container and display the detection results through the display screen, so that the staff can obtain the temperature information of the maleic anhydride solution. At the same time, the temperature sensor electrically connected to the heating equipment can automatically control the heating equipment according to the change of the temperature of the maleic anhydride solution, prompting the heating equipment to automatically open and close according to the temperature of the maleic anhydride solution, thereby keeping the maleic anhydride solution in a suitable temperature environment at all times, and avoiding the maleic anhydride solution from crystallizing due to the temperature being too low.
[0011] Furthermore, the outer circumferential surface of the maleic anhydride container is provided with a heat-insulating layer.
[0012] Through the above solution, the insulation layer can keep the maleic anhydride solution in the maleic anhydride container warm, preventing the maleic anhydride solution in the maleic anhydride container from cooling too quickly and crystallizing, and ensuring that the maleic anhydride solution is kept in a suitable temperature environment.
[0013] Furthermore, the top ends of the maleic anhydride container and the C5 container are both threadedly connected with a top cover, and a feeding pipe is provided inside each of the top covers.
[0014] Through the above solution, the top cover can protect the solution in the maleic anhydride container and the C5 container to prevent dirt from falling in and affecting their quality. The feeding pipe on the top cover facilitates feeding into the maleic anhydride container or the C5 container.
[0015] Furthermore, a sealing sheet is fixedly connected to the inner top wall of each top cover.
[0016] Through the above solution, the sealing effect between the top cover and its corresponding container is improved, preventing the solution from leaking easily.
[0017] Furthermore, a feed pipe is provided at the bottom of the agitator, the bottom of the feed pipe is fixedly connected to the top of the tower reactor, and a second solenoid valve is provided on the outer circumference of the feed pipe.
[0018] Through the above solution, the mixed solution stirred in the stirrer can be injected into the tower reactor below through the discharge pipe, and the discharge pipe can be controlled to be on and off by the second solenoid valve.
[0019] Furthermore, the heights of the maleic anhydride container and the C5 container are higher than the height of the agitator, and the height of the agitator is higher than the height of the tower reactor.
[0020] Through the above scheme, the C5 solution and maleic anhydride solution can flow from top to bottom under the action of gravity, thereby completing the stirring and dripping operations of the C5 solution and maleic anhydride solution.
[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0022] The precise dripping device for C5 and maleic anhydride solution arranges a first electromagnetic valve and a flow meter on the outer circumferential surface of an infusion tube, and electrically connects the flow meter and the first electromagnetic valve, so that the dripping injection amount of the C5 or maleic anhydride solution can be precisely controlled to ensure the quality of subsequent reaction operations. Agitators are arranged at the output ends of the two infusion tubes to promote uniform mixing of the C5 and maleic anhydride solutions, thereby improving the efficiency of subsequent reaction operations. This solves the problem that the accuracy of the injection amount of the C5 and maleic anhydride solutions will affect the quality of the subsequent reaction, and that directly injecting the C5 and maleic anhydride solutions into a tower reactor will easily lead to uneven mixing of the two, thereby affecting the reaction efficiency.

A display screen 8 is provided on the front of the temperature sensor 7. The temperature sensor 7 can detect the temperature of the maleic anhydride solution in the maleic anhydride container 4 and display the detection result through the display screen 8, so that the staff can obtain the temperature information of the maleic anhydride solution. At the same time, the temperature sensor 7 electrically connected to the heating device 5 can automatically control the heating device 5 according to the change of the temperature of the maleic anhydride solution, prompting the heating device 5 to automatically open and close according to the temperature of the maleic anhydride solution, thereby keeping the maleic anhydride solution in a suitable temperature environment at all times, and avoiding crystallization of the maleic anhydride solution due to excessively low temperature.
[0033] See also Figure 1 and Figure 3 The outer circumferential surface of the maleic anhydride container 4 is provided with an insulation layer 9, which can keep the maleic anhydride solution in the maleic anhydride container 4 warm, preventing the maleic anhydride solution in the maleic anhydride container 4 from cooling too quickly and crystallizing, and ensuring that the maleic anhydride solution is kept in a suitable temperature environment.
[0034] See also Figure 1 、 Figure 3 and Figure 4 The top of the maleic anhydride container 4 and the C5 container 10 are both threadedly connected with a top cover 11, and each top cover 11 is provided with a feeding pipe 12 inside.

[0036] See also Figure 1 and Figure 2 A discharge pipe 19 is provided at the bottom of the agitator 2, and the bottom of the discharge pipe 19 is fixedly connected to the top of the tower reactor 1.

[0037] See also Figure 1 The heights of the maleic anhydride container 4 and the C5 container 10 are higher than the height of the agitator 2, and the height of the agitator 2 is higher than the height of the tower reactor 1, which enables the C5 solution and the maleic anhydride solution to circulate from top to bottom under the action of gravity, thereby completing the stirring and dripping operations of the C5 solution and the maleic anhydride solution.
[0038] In this embodiment, a precise dripping device for C5 and maleic anhydride solution is provided. By arranging a first solenoid valve 14 and a flow meter 15 on the outer circumferential surface of the infusion tube 3 and electrically connecting the flow meter 15 and the first solenoid valve 14, the dripping injection amount of the C5 or maleic anhydride solution can be precisely controlled to ensure the quality of subsequent reaction operations. By arranging a stirrer 2 at the output ends of the two infusion tubes 3, the C5 and maleic anhydride solutions can be uniformly mixed, thereby improving the efficiency of subsequent reaction operations. This solves the problem that the accuracy of the injection amount of the C5 and maleic anhydride solutions will affect the quality of the subsequent reaction, and that directly injecting the C5 and maleic anhydride solutions into the tower reactor 1 will easily lead to uneven mixing of the two, thereby affecting the reaction efficiency.
[0039] It should be noted that the heights of the maleic anhydride container 4 and the C5 container 10 are consistent.
[0040] The working principle of the above embodiment is:
[0041] When it is necessary to react the C5 and maleic anhydride solutions, the maleic anhydride solution is injected into the maleic anhydride container 4, and the C5 solution is injected into the C5 container 10. Then, the first solenoid valves 14 below the maleic anhydride container 4 and the C5 container 10 are opened respectively. Then, the maleic anhydride solution and the C5 solution flow out from the infusion pipe 3 below them to the inside of the stirrer 2 below. The flow meter 15 can detect the amount of solution flowing down. The flow meter 15 on the infusion pipe 3 can be set respectively. When the solution flow reaches the set amount, the flow meter 15 will control the corresponding first solenoid valve 14 to close, accurately controlling the injection amount of the maleic anhydride solution and the C5 solution. When the maleic anhydride solution and the C5 solution are completely injected into the stirrer 2, The starting motor 16 drives the stirring shaft 17 and the stirring blade 18 to stir, so that the maleic anhydride solution and the C5 solution are evenly mixed and stirred. Finally, the second solenoid valve 20 is opened to promote the flow of the discharge pipe 19, and the stirred maleic anhydride and C5 mixture is injected into the tower reactor 1 below for subsequent reaction. The temperature sensor 7 can detect the temperature of the maleic anhydride solution in the maleic anhydride container 4 and display the detection result through the display screen 8. At the same time, the temperature sensor 7 can automatically control the heating device 5 according to the change of the maleic anhydride solution temperature, so that the heating device 5 is automatically opened and closed according to the temperature of the maleic anhydride solution, thereby keeping the maleic anhydride solution in a suitable temperature environment at all times, and avoiding the maleic anhydride solution from being too cold and crystallizing.
