Description

Technical Field

[0001] The utility model belongs to the technical field of chemical synthesis, and in particular relates to an ammonia synthesis device. Background Art

[0002] Ammonia synthesis production equipment generally uses a circulating mixer. First, hydrogen and nitrogen are filled into the machine body, and then circulated and mixed to obtain a pure hydrogen-nitrogen mixture. The mixture is then compressed to high pressure and synthesized into ammonia under high temperature and the presence of a catalyst.

[0003] In the process of the existing circulating mixer charging hydrogen and nitrogen into the machine body through the charging pipes, the positions of the two charging pipes are fixed, so that the distribution of hydrogen and nitrogen is concentrated on one side respectively. Initially, the two gases enter the machine body without mixing with each other. In order to ensure that the hydrogen and nitrogen components in the hydrogen-nitrogen mixed gas are uniform, a long time of stirring is required, resulting in low mixing efficiency.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 and Figure 2 As shown, an ammonia synthesis device includes a synthesis tank 1, the bottom outer wall of the synthesis tank 1 is fixedly connected with a support leg, the top of the synthesis tank 1 is provided with a feed port for feeding a catalyst, the bottom is provided with a discharge port, the feed port and the discharge port are both provided with a first solenoid valve, a hydrogen pipe 11 and a nitrogen pipe 12 are respectively fixedly installed on both sides of the synthesis tank 1, the hydrogen pipe 11 and the nitrogen pipe 12 are both provided with a second solenoid valve, and a mixing mechanism for mixing gas and a driving mechanism for controlling the rotation of the mixing mechanism are installed inside the synthesis tank 1, the hydrogen pipe 11 and the nitrogen pipe 12 A docking sleeve 13 is fixedly connected therebetween, and the docking sleeve 13 is fixedly connected to the synthesis tank 1 through a support member. The support member adopts a suspension rod, which is used to share the pressure of the docking sleeve 13 on the hydrogen pipe 11 and the nitrogen pipe 12. The two through holes of the docking sleeve 13 are respectively interconnected with the hydrogen pipe 11 and the nitrogen pipe 12, and an alternating turntable 2 connected to the driving mechanism is rotatably arranged inside the docking sleeve 13. The alternating turntable 2 is provided with a first gas transmission hole 21 and multiple second gas transmission holes 22. The second gas transmission holes 22 are respectively interconnected with the first gas transmission hole 21 and the through holes of the docking sleeve 13.

[0020] Specifically, the driving mechanism drives the alternating turntable 2 to rotate, so that the second gas delivery hole 22 intermittently communicates with the hydrogen pipe 11 and the nitrogen pipe 12, so that hydrogen and nitrogen alternately enter the interior of the synthesis tank 1. At the same time, the driving mechanism can also drive the stirring mechanism to mix them, thereby reducing the stirring process time and improving the efficiency of ammonia synthesis.

[0021] like Figure 1 and Figure 2 As shown, the stirring mechanism includes a guide rail 6, which is annular and fixedly mounted on the inner wall of the synthesis tank 1, and a guide slide 7 is slidably mounted on the guide rail 6, which is annular and fixedly connected to a gear ring 8 and blades 9 on both sides of the guide slide 7, respectively. The blades 9 are arranged in a ring array, and the dots of the synthesis tank 1, the guide rail 6, and the guide slide 7 all overlap.

[0022] like Figure 2 As shown, the driving mechanism includes a driving member 3, which adopts a servo motor. The driving member 3 is fixed to the outer wall of the synthesis tank 1 through a mounting base, and the output end of the driving member 3 is fixedly connected to a transmission shaft 4. The end of the transmission shaft 4 away from the driving member 3 passes through one side of the synthesis tank 1 and is fixedly connected to the alternating turntable 2.

[0023] Specifically, while the driving member 3 drives the transmission shaft 4 to rotate, the transmission shaft 4 will drive the alternating turntable 2 to rotate together. At this time, the multiple second gas holes 22 will be intermittently connected with the hydrogen pipe 11 and the nitrogen pipe 12. Only after the second gas holes 22 are aligned and connected with the hydrogen pipe 11 or the nitrogen pipe 12, can hydrogen or nitrogen be sprayed from the first gas holes 21 to the interior of the synthesis tank 1, so that hydrogen and nitrogen alternately enter the interior of the synthesis tank 1.

[0024] like Figure 2 As shown, the outer ring fixed sleeve of the transmission shaft 4 is provided with a gear 5, and the gear 5 is meshed with the gear ring 8 for transmission.

[0025] Specifically, while the transmission shaft 4 drives the alternating turntable 2 to rotate, the gear 5 will also rotate synchronously. The gear 5 will drive the guide slide 7 to rotate in the guide rail 6 through the engagement with the gear ring 8. The rotation of the guide slide 7 will drive the multiple blades 9 connected thereto to rotate around the center of the guide slide 7, thereby stirring and mixing the hydrogen and nitrogen.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
