[0002] Ammonia synthesis reactors are one of the core pieces of equipment used in the chemical industry for ammonia synthesis, and are widely used in fertilizer production, fine chemical manufacturing, and other ammonia-related industrial processes. With the increasing global demand for agricultural production and energy, the demand for ammonia production is also growing, and the issues of high efficiency, energy conservation, and environmental protection in the ammonia synthesis process are becoming increasingly prominent.

[0003] Traditional ammonia synthesis reactors mostly use high temperature and high pressure conditions to promote the reaction of nitrogen and hydrogen. For this reason, their shells are usually made of carbon steel or alloy steel, which can withstand high pressure and temperature and have better corrosion resistance and high temperature resistance. However, in actual use, the large size of the ammonia synthesis reactor makes the shell extremely inconvenient to transport and handle. Therefore, an ammonia synthesis reactor is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-5This utility model provides an embodiment of an ammonia synthesis reactor, comprising a base 1, a connecting ring 2, and a top seat 3. A top ring 4 is fixedly connected to the outer periphery of the base 1, and a bottom ring 5 is fixedly connected to the outer periphery of the top seat 3. A second top ring 6 and a second bottom ring 7 are fixedly connected from top to bottom to the outer side of the connecting ring 2. Positioning components are installed between the base 1, the connecting ring 2, and the top seat 3. Bolts 8 are slidably connected to the middle of the first top ring 4, the first bottom ring 5, the second top ring 6, and the second bottom ring 7. Nuts 13 are threadedly connected to the outer periphery of the bolts 8. The positioning components include... It includes multiple positioning blocks 14, which are fixedly connected to the bottom of bottom ring 1 5 and bottom ring 2 7 respectively. Multiple positioning grooves 10 are opened in the middle of top ring 1 4 and top ring 2 6 respectively. Multiple positioning blocks 14 are slidably connected between multiple positioning grooves 10. Through holes 9 are opened in the middle of top ring 1 4, bottom ring 1 5, top ring 2 6 and bottom ring 2 7 respectively. Bolts 8 are slidably connected in the middle of through holes 9. The outer diameter of multiple positioning blocks 14 is the same as the inner diameter of multiple positioning grooves 10. Multiple positioning blocks 14 and multiple positioning grooves 10 are all conical. Firstly, the modular base 1, connecting ring 2, and top seat 3 improve the convenience of transportation and reduce waste of transportation resources. At the same time, the positioning blocks 14 at the bottom of bottom ring 1 5 and bottom ring 2 7 are aligned with the positioning grooves 10 in the middle of top ring 1 4 and top ring 2 6 and inserted, so that base 1, connecting ring 2, and top seat 3 can be quickly assembled. The conical positioning blocks 14 and positioning grooves 10 further enhance the ease of assembly. Then, top ring 1 4 and bottom ring 2 7, top ring 2 6 and bottom ring 2 7, and bottom ring 1 5 and top ring 2 6 are fixed in sequence with bolts 8 and nuts 13, thereby improving the ease of fixing. At the same time, the modular connecting ring 2 can be used to increase the length of the equipment as needed.

[0032] Reference Figures 2-7 An outer locking block 11 and an inner locking block 15 are fixedly connected to the base 1 and the top seat 3 on the side near the connecting ring 2, respectively. Another outer locking block 11 and another inner locking block 15 are fixedly connected to the upper and lower sides of the connecting ring 2, respectively. An inner locking groove 12 and an outer locking groove 16 are respectively opened on the side of the base 1 and the top seat 3 near the connecting ring 2, respectively. Another inner locking groove 12 and another outer locking groove 16 are respectively opened on the upper and lower sides of the connecting ring 2. The outer locking block 11 and the inner locking block 15 are slidably connected to the middle of the outer locking groove 16 and the inner locking groove 12, respectively. A sealing ring 17 is fixedly connected to the middle of the inner locking groove 12 and the outer locking groove 16, respectively. The outer diameter of the outer locking block 11 and the inner locking block 15 is the same as the inner diameter of the inner locking groove 12 and the outer locking groove 16, respectively. While the base 1, connecting ring 2, and top seat 3 are being assembled, the outer locking block 11 and the inner locking block 15 are respectively inserted between the inner locking groove 12 and the outer locking groove 16 and squeezed against the sealing ring 17. Thus, under the interlacing action of the outer locking block 11 and the inner locking block 15, the sealing effect at the connection is ensured. Furthermore, since the outer diameters of the outer locking block 11 and the inner locking block 15 are the same as the inner diameters of the inner locking groove 12 and the outer locking groove 16, the gaps at the connection are reduced, thereby further improving the sealing effect.

[0033] Working principle: First, the positioning blocks 14 at the bottom of bottom ring 5 and bottom ring 7 are inserted into the positioning grooves 10 of top ring 6 and top ring 4, so that the modular base 1, connecting ring 2, and top seat 3 can be quickly positioned and assembled. Then, the top ring 4 and bottom ring 7, top ring 6 and bottom ring 7, and bottom ring 5 and top ring 6 are connected in sequence by bolts 8 and nuts 13. Thus, the modular base 1, connecting ring 2, and top seat 3 facilitate transportation and handling, and also facilitate assembly. Furthermore, the length of the equipment can be increased as needed under the action of the modular connecting ring 2.

[0034] While the base 1, connecting ring 2, and top seat 3 are being assembled, the outer locking block 11 and the inner locking block 15 will be inserted between the inner locking groove 12 and the outer locking groove 16 respectively and squeezed against the sealing ring 17. Thus, under the interlacing action of the outer locking block 11 and the inner locking block 15, the sealing effect at the connection point is improved.
