Description

Technical Field

[0001] The present application relates to the technical field of synthetic ammonia plant layout, and in particular to a modular layout system for an offshore synthetic ammonia plant. Background Art

[0002] An ammonia synthesis plant is a device that reacts nitrogen and hydrogen under high temperature and pressure to produce ammonia. Its core process includes feed gas processing, reaction, catalytic action, gas separation, and energy recovery. Widely used in industries such as fertilizers, pesticides, synthetic rubber, and plastics, ammonia synthesis plants are indispensable equipment in the modern chemical industry. As a basic inorganic chemical raw material, ammonia plays a vital role in the fertilizer industry and basic organic chemical industry.

[0003] Deploying synthetic ammonia modules offshore essentially optimizes geographical location, resource utilization, and technological integration to achieve cost reduction, environmental friendliness, and flexible operations. This approach is particularly well-suited for scenarios where raw material production is offshore, product exports rely on seaborne shipping, and land-based resources are limited. With the advancement of marine engineering technology and green energy, this model is expected to become a key driver of the chemical industry's transformation and upgrading.

[0004] Deploying ammonia synthesis modules offshore often requires constructing large-scale infrastructure platforms on the sea surface, which serve as a carrier for the rational distribution of the modules. This process requires the transportation and installation of infrastructure materials, which relies on large-scale lifting equipment. This results in high construction costs and a long construction period, reducing the efficiency of offshore ammonia synthesis plant deployment. Summary of the Invention

A floating platform is installed at the bottom of each device, a floating airbag is installed at the bottom of the floating platform, and a center of gravity adjustment component is provided on the floating platform. The center of gravity adjustment component includes a water tank, a water inlet pump, and a water outlet pump. The water tank is connected to the bottom of the floating platform, and a vent pipe connected to the outside is provided on the top of the water tank. The water inlet pump is installed on one side of the water tank, the water pumping end of the water inlet pump is connected to the external seawater, and the water outlet end is connected to the interior of the water tank. The water outlet pump is installed on the other side of the water tank, the water outlet pump water pumping end is connected to the interior of the water tank, and the water outlet end is connected to the external seawater. Soft connection components are provided between each device to limit the floating platform from floating on the seawater.

[0007] By adopting the above technical solution, each device is floated on the seawater by providing a floating platform and floating airbags. Flexible connection components are used to restrain each floating platform to prevent it from drifting. When the sea surface is calm, the bottom wall of the floating platform is close to the water surface. When the waves are large, the water inlet pump is activated to allow seawater to enter the water tank. The air in the water tank is discharged through the vent pipe, causing the floating platform to sink until the top wall of the floating platform is close to the water surface, achieving the effect of adjusting the center of gravity of the device. By providing a center of gravity adjustment component, the gravity of the floating platform is increased by filling the water tank with water according to the sea surface conditions, causing the entire device to descend, thereby lowering the center of gravity and improving the device's stability on the sea surface. The above structure can be assembled on land and placed on the sea surface by lifting for direct use. In conjunction with the flexible connection components, the various devices form a whole and are mutually constrained.

In normal operation, the hollow buoys are placed between the sea surface and the bottom of the platform when it sinks. The balancing assembly is used to provide buoyancy at the four corners of the platform. When the waves are strong, the platform is prone to swaying with large amplitude. The balancing assembly can quickly provide buoyancy to the lower part of the platform, quickly righting the platform and gradually reducing the swaying amplitude, achieving the effect of quickly assisting in stabilizing the platform on the sea surface.

[0010] Optionally, the soft connection assembly includes a stone anchor, a steel wire rope, a cross clamp and a connecting rod. Several steel wire ropes are provided, four of which form a rectangular area, and the remaining steel wire ropes are divided into several rectangular accommodating areas within the rectangular area. The stone anchor is provided in four directions of the rectangular area, and the stone anchor is also connected to the side wall of the rectangular area through the steel wire rope. All the floating platforms are located in the rectangular area, and one floating platform corresponds to one accommodating area. The cross clamp is provided between two vertically staggered steel wire ropes. One end of the connecting rod is detachably connected to the side wall of the floating platform, and the other end is connected to a ring, and the steel wire rope passes through the ring.

[0011] By adopting the above technical solution, a rectangular area and several accommodating areas are arranged through a cross clamp, and the stone anchor is sunk to the seabed to stabilize the four directions of the rectangular area. With this as the base, the side wall of the floating platform is installed on the wire rope through the loop on the connecting rod, so as to restrict each device to the designated accommodating area, while allowing the floating platform to rise and fall to a certain extent.

[0012] Optionally, a mounting assembly is provided on the floating platform, and the mounting assembly includes a mounting shell, a limiting shell and a mounting block. The mounting shell is connected to the side wall of the floating platform, and the limiting shell is provided on the mounting shell.

A limiting assembly for limiting the movement of the limiting shell is provided on the mounting shell, and the mounting block is provided between the mounting shell and the limiting shell. One end of the connecting rod is rotatably connected to the mounting block and is located in the avoidance groove.

[0013] By adopting the above technical solution, when installing the connecting rod, the mounting block is inserted into the mounting shell, the limiting shell is covered, and the limiting assembly is used to prevent the limiting shell from moving, thereby realizing a detachable connection of the connecting rod end.

[0014] Optionally, the limiting assembly includes a right-angle plate, a connecting platform, a slider, a rotating plate, a limiting column and a tension spring, the mounting shell and the limiting shell are both arranged in a rectangular shape, the right-angle plate is connected to one of the two corners on the same side of the mounting shell, the limiting shell is located between the two right-angle plates, the connecting platform is connected to the side wall of the limiting shell, the slider slides on the connecting platform, one end of the rotating plate is rotatably connected to the slider, and the other end is provided with a waist-shaped groove, and the waist-shaped groove is provided with a accommodating groove, the limiting column is connected to the mounting shell, and the end of the limiting column is connected to the limiting plate, the tension spring is installed between the connecting platform and the slider, and is located above the limiting column. When limiting, the length direction of the waist-shaped groove is parallel to the moving direction of the slider, the limiting column is located in the waist-shaped groove, and the other end of the rotating plate is located between the limiting plate and the mounting shell.

[0015] By adopting the above technical solution, when installing the limiting shell, the limiting shell is inserted between the two right-angle plates, and then the rotating plate is flipped and pulled, the slider drops, and the tension spring is in a stretched state until the limiting plate passes through the accommodating groove and the limiting column is located in the waist-shaped groove. The rotating plate is released, and the slider rises under the action of the tension spring, driving the other end of the rotating plate to enter between the limiting plate and the side wall of the installation shell to limit the rotation of the rotating plate, thereby achieving the effect of limiting the movement of the limiting shell.

[0016] Optionally, a floating sleeve is provided on the surface of the steel wire rope.

[0017] By adopting the above technical solution and setting the floating sleeve, on the one hand, the buoyancy of the wire rope is increased to a certain extent, so that the wire rope can better restrict the floating platform, and on the other hand, the corrosion of the seawater to the wire rope is reduced, thereby extending the service life of the wire rope.

[0018] Optionally, a house is provided on the floating platform, a plurality of photovoltaic panels are installed on the top of the house, a battery and a controller are built into the house, and the photovoltaic panels and the controller are electrically connected to the battery.

[0019] By adopting the above technical solution, by setting up a room, photovoltaic panels and controllers, a closed environment is provided for the equipment inside the room, making the synthetic ammonia device more suitable for environments such as high salt fog and low-temperature sea areas, reducing the corrosion of the external environment on the equipment. At the same time, in conjunction with photovoltaic panels and batteries, the equipment is continuously powered and operated, providing a stable operating environment for the equipment.

[0020] Optionally, the surfaces of the floating platform and the steel wire rope are both coated with an anti-corrosion coating.

[0021] By adopting the above technical solution, the anti-corrosion coating is used to isolate the acidic substances in the seawater from corroding the floating platform and the steel wire rope, thereby ensuring the structural strength of the floating platform and extending the service life of the floating platform and the steel wire rope.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a floating platform and a floating airbag, each device is floated on the seawater, and each floating platform is restricted by a soft connection component to prevent the floating platform from drifting. When the sea surface is calm, the bottom wall of the floating platform is close to the water surface; when the waves are large, the water inlet pump is started to allow seawater to enter the water tank, and the air in the water tank is discharged through the vent pipe, causing the floating platform to sink until the top wall of the floating platform is close to the water surface, thereby achieving the effect of adjusting the center of gravity of the equipment. By setting up a center of gravity adjustment component, according to the sea surface conditions, the gravity of the floating platform is increased by injecting water into the water tank, so that the entire equipment is lowered to lower the center of gravity of the equipment and improve the stability of the equipment on the sea surface. The above structure can be assembled on land and placed on the sea surface by lifting and can be put into use directly. With the help of the soft connection component, each device forms a whole and is constrained to each other. Compared with the existing infrastructure platform, the transportation and lifting of the substrate are reduced, and the installation time of the synthetic ammonia unit at sea is shortened, thereby improving the layout efficiency of the synthetic ammonia unit at sea. 2. During installation, several hollow buoys are placed on the connecting column, and finally the retaining ring is threaded into the end of the connecting column to stabilize the hollow buoys. Under normal conditions, the hollow buoys are placed between the sea surface and the bottom of the platform when it sinks. The balancing assembly is used to provide buoyancy for the four corners of the platform. When the waves are large, the platform is prone to swaying with a large amplitude. The balancing assembly can quickly provide buoyancy to the lower part of the platform to quickly right the platform, and the swaying amplitude is gradually reduced, achieving the effect of quickly assisting in stabilizing the platform on the sea surface. 3. Using a cross clamp, a rectangular area and several accommodation areas are laid out. Stone anchors are sunk into the seabed to stabilize the four directions of the rectangular area. Using this as the base, the side walls of the floating platform are attached to the wire rope through the loops on the connecting rods, thereby confining each device within the designated accommodation area while allowing the floating platform to rise and fall to a certain extent. 4. When installing the limiting shell, insert the limiting shell between the two right-angle plates, then flip and pull the rotating plate, the slider drops, and the tension spring is in a stretched state until the limiting plate passes through the accommodating groove and the limiting column is located in the waist-shaped groove. Release the rotating plate, and the slider rises under the action of the tension spring, driving the other end of the rotating plate to enter between the limiting plate and the side wall of the mounting shell to limit the rotation of the rotating plate, thereby achieving the effect of limiting the movement of the limiting shell.

A plurality of photovoltaic panels 12 are mounted on the top wall of housing 11. Housing 11 houses a battery and a controller, both of which are electrically connected to the controller. A floating airbag 13, filled with air, is mounted on the bottom wall of the floating platform 1.

[0034] Reference Figure 3 The floating platform 1 is provided with a center of gravity adjustment component 2, which includes a water tank 21, an inlet pump 22 and an outlet pump 23. The water tank 21 is welded to the bottom wall of the floating platform 1 and is located within the range of the floating airbag 13.

The water outlet pump 23 is installed on the other side of the water tank 21, and the water pumping end is connected to the inside of the water tank 21, and the water outlet end is connected to the external seawater.

[0035] When the sea is calm, the water outlet pump 23 is used to discharge the seawater inside the water tank 21, and the floating platform 1 rises until the bottom wall of the floating platform 1 is close to the sea surface; when the sea is windy and rough, the water inlet pump 22 is started to allow external seawater to enter the water tank 21, and the air inside the water tank 21 is discharged along the ventilation pipe 211 to increase the weight of the floating platform 1, causing the center of gravity of the floating platform 1 to drop and sink until the top wall of the floating platform 1 is close to the sea surface, thereby achieving the effect of stabilizing the floating platform 1 according to the sea surface conditions.

[0036] Reference Figure 2 and Figure 3 In order to further stabilize the floating platform 1, a balancing assembly 3 is provided on the floating platform 1. The balancing assembly 3 includes a tilting platform 31, a connecting column 32, a hollow buoy 33, a retaining ring 34 and a fixing ring 35.

The anti-corrosion coating is used to extend the service life of the floating platform 1 and the steel wire rope 42.

[0039] Reference Figure 2 and Figure 5 Several mounting assemblies 5 are installed on the sidewalls of the platform 1. These assemblies 5 include a mounting shell 51, a restraining shell 52, and a mounting block 53. The mounting shell 51 is welded to the sidewall of the platform 1. The restraining shell 52 is positioned on the mounting shell 51, with a clearance groove defined between the two shells. The mounting block 53 is positioned between the mounting shell 51 and the restraining shell 52. One end of the connecting rod 44 is hinged to the mounting block 53 and positioned within the clearance groove. The other end is fixedly connected to a ferrule 441, through which the wire rope 42 passes.

[0040] Reference Figure 5 and Figure 6, a limiting assembly 6 is provided on both opposite side walls of the limiting shell 52, and the limiting assembly 6 includes a right-angle plate 61, a connecting platform 62, a slider 63, a rotating plate 64, a limiting column 65 and a tension spring 66. A right-angle plate 61 is welded at the two corners on the same side of the mounting shell 51, and the limiting shell 52 is located inside the two right-angle plates 61. A connecting platform 62 is welded on the opposite side walls of the limiting shell 52, and a T-rail is welded on the connecting platform 62. The slider 63 slides vertically on the T-rail. One end of the rotating plate 64 is hinged to the slider 63, and the other end is provided with a waist-shaped groove 641 and a receiving groove 642. When limiting, the waist-shaped groove 641 is parallel to the moving direction of the slider 63, and the receiving groove 642 is a circular groove and is located on the path of the waist-shaped groove 641.

[0042] The implementation principle of the modular layout system of the offshore synthetic ammonia plant in the embodiment of the present application is as follows: by setting up a floating platform 1 and a floating air bag 13, the floating platform 1 floats on the sea surface. When the sea surface is calm, the water outlet pump 23 is started to pump out the seawater in the water tank 21, so that the floating platform 1 rises until the bottom wall of the floating platform 1 is close to the sea surface. When the sea surface is rough, the water inlet pump 22 is started, and the seawater enters the water tank 21 to increase the weight of the floating platform 1 and make the floating platform 1 sink. At the same time, the hollow buoy 33 below the sea surface is used to improve the stability of the floating platform 1. In the accommodating area 422 defined by the rope 42, one end of the connecting rod 44 is mounted on the wire rope 42 through the ring 441, and the mounting block 53 at the other end is placed in the mounting shell 51. The limiting shell 52 is mounted on the mounting block 53, and the rotating plate 64 is pulled and rotated. The limiting plate 651 passes through the accommodating groove 642, so that the other end of the rotating plate 64 is located between the limiting plate 651 and the side wall of the mounting shell 51 to install the connecting rod 44, thereby realizing the connection between the four sides of the floating platform 1 and the four sides of the accommodating area 422, so as to stabilize the stable distribution of various equipment on the sea surface.

[0043] By providing a center of gravity adjustment component 2, the gravity of the floating platform 1 is increased by filling the water tank 21 with water according to the sea surface conditions, so that the entire equipment is lowered to lower the center of gravity of the equipment and improve the stability of the equipment on the sea surface. The above structure can be assembled on land and placed on the sea surface by lifting and can be put into use directly. In conjunction with the soft connection component 4, the various devices form a whole and constrain each other. Compared with the infrastructure platform of the prior art, the transportation and lifting of the substrate are reduced, the installation time of the synthetic ammonia unit 06 at sea is shortened, and the layout efficiency of the synthetic ammonia unit 06 at sea is improved.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
