Description

Technical Field

[0001] This utility model belongs to the field of fireproof structure technology, and in particular relates to a fireproof partition structure for the process area of ​​an LNG receiving station. Background Technology

[0002] LNG receiving terminal process areas involve numerous high-pressure, low-temperature, and flammable / explosive equipment and pipelines. The LNG stored there, as well as the natural gas produced from its regasification, pose an extremely high fire hazard. Currently, traditional fire-resistant partition structures are insufficient to meet their specific requirements. For example, under high-temperature, high-pressure, and complex process conditions, their fire resistance is unstable, and fire compartments are prone to failure. Once a fire occurs, it can spread extremely easily, causing significant property damage and casualties.

[0003] However, the existing fire-resistant partition structure of the process area in LNG receiving terminals has the following disadvantages:

[0004] (1) The existing fireproof partition structure of the process area of ​​the LNG receiving terminal is usually an integrated type, which makes facility maintenance difficult and greatly increases maintenance costs and difficulty;

[0005] (2) The existing fireproof partition structure of the process area of ​​the LNG receiving terminal is difficult to effectively prevent the partition wall from being burned through or collapsing, thus affecting its fireproof partition function.

[0006] Therefore, there is an urgent need to design a fireproof partition structure for the process area of ​​an LNG receiving terminal to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a fireproof partition structure for the process area of ​​an LNG receiving station, which effectively solves the problems of poor facility maintainability and easy burning or collapse of partition walls in the prior art.

[0008] To achieve the above objectives, the specific technical solution of the fireproof partition structure for the process area of ​​an LNG receiving station according to this utility model is as follows:

[0009] A fireproof partition structure for the process area of ​​an LNG receiving terminal includes: two wall columns, a partition wall, a fixing assembly, and a spraying assembly;

[0010] Each of the two wall columns is provided with a fixing component on one side opposite to the other, and a partition wall is detachably connected to the opposite side of the fixing component.

[0011] The spraying assembly includes a mounting bracket, a water pipe, and a nozzle. The mounting bracket is fixedly connected to the top of the partition wall, and the water pipe is fixedly installed at the lower end of the mounting bracket and located inside the partition wall. One end of the water pipe is connected to the nozzle.

[0012] Furthermore, the fixing assembly includes a mounting plate fixedly connected to one side of the wall column and a connecting plate fixedly connected to one side of the partition wall. The connecting plate has countersunk holes for placing screws, and the mounting plate has threaded grooves that engage with the screws.

[0013] Furthermore, a positioning block is fixedly provided on the side of the connecting plate away from the partition wall, and a positioning groove adapted to the positioning block is provided on the side of the mounting plate away from the wall column.

[0014] Furthermore, the partition wall includes a concrete layer, and a fireproof layer is fixedly connected to both the front and back of the concrete layer.

[0015] Furthermore, the spraying assembly also includes a mounting block rotatably connected to the mounting bracket, and the spray head is mounted on the lower end of the mounting block.

[0016] Furthermore, the spraying assembly also includes a fixed frame, a rotating shaft, and blades. The output end of the nozzle is fixedly connected to the fixed frame, and a rotating hole is provided at the bottom of the fixed frame. One end of the rotating shaft is fixedly connected to the blades, and the other end of the rotating shaft is rotatably connected to the rotating hole.

[0017] Furthermore, hoisting assemblies are installed on both the front and back of the partition wall.

[0018] Furthermore, the hoisting assembly includes a support rod and lifting rings. The support rod passes through the partition wall and is fixedly connected to the partition wall. Lifting rings are fixedly installed at both ends of the support rod.

[0019] Furthermore, the hoisting assembly includes a support rod, bolts, and lifting rings. The support rod passes through the partition wall and is fixedly connected to the partition wall. The bolts are fixedly connected to the lifting rings and threadedly connected to the support rods. Both ends of the support rods are fixedly provided with lifting rings by bolts.

[0020] Furthermore, a washer is provided between the countersunk hole and the screw, and the washer is fitted onto the screw.

[0021] The fireproof partition structure of the LNG receiving terminal process area of ​​this utility model has the following advantages:

[0022] 1. Improved Maintainability: Through the use of partition walls, mounting plates, connecting plates, and screws, during installation, the positioning blocks are aligned with the positioning grooves using a hoisting assembly. This aligns the countersunk holes of the connecting plate with the threaded grooves of the mounting plate, allowing the screws to be screwed in to securely fix the partition wall and mounting plate. This detachable connection method significantly reduces maintenance costs and difficulty, substantially improving the maintainability of the facility.

[0023] 2. Enhanced fire resistance: With the help of mounting brackets, water pipes, mounting blocks and sprinklers, when a fire occurs, the water in the pipes circulates continuously, exchanging heat with the partition wall through the pipe wall. At the same time, the sprinklers spray water onto the partition wall, and the blades expand the spray coverage area, effectively reducing the temperature of the partition wall, maintaining its structural strength and fire resistance, preventing the partition wall from being burned through or collapsing, and giving full play to its fire-resistant separation function.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0033] The following reference Figures 1 to 5 This invention describes a fireproof partition structure for the process area of ​​an LNG receiving station.

[0034] A fireproof partition structure for the process area of ​​an LNG receiving terminal includes: two wall columns 1, a partition wall 2, a fixing assembly 3, and a spraying assembly 4;

[0035] Each of the two wall columns 1 is provided with a fixing component 3 on one side opposite to the other, and a partition wall 2 is detachably connected to the opposite side of the fixing component 3.

[0036] The spraying assembly 4 includes a mounting bracket 41, a water pipe 42, and a nozzle 43. The mounting bracket 41 is fixedly connected to the top of the partition wall 2. The water pipe 42 is fixedly installed at the lower end of the mounting bracket 41 and located inside the partition wall 2. One end of the water pipe 42 is connected to the nozzle 43.

[0037] Specifically, when a fire occurs, the water in the water pipe 42 circulates continuously, exchanging heat with the partition wall 2 through the pipe wall. At the same time, the sprinkler head 43 sprays water onto the partition wall 2, effectively reducing the temperature of the partition wall 2, maintaining its structural strength and fire resistance, preventing the partition wall 2 from being burned through or collapsing, and fully exerting its fire-resistant partition function.

[0038] Preferably, the lower end of the mounting bracket 41 is provided with a plurality of water pipes 42 and nozzles 43, which are respectively located on the front and back of the partition wall 2.

[0039] Furthermore, the fixing component 3 includes a mounting plate 31 fixedly connected to one side of the wall column 1 and a connecting plate 32 fixedly connected to one side of the partition wall 2. The connecting plate 32 has a countersunk hole 321 for placing a screw 322, and the mounting plate 31 has a threaded groove that engages with the screw 322.

[0040] Specifically, mounting plates 31 are fixed on the opposite sides of the two wall columns 1. The mounting plates 31 have threaded grooves that are compatible with screws 322. When the partition wall 2 needs maintenance or replacement, it can be disassembled simply by unscrewing the screws 322 without damaging the overall structure. This greatly reduces maintenance costs and operational difficulty, and significantly improves the maintainability of the facility.

[0041] Furthermore, a positioning block 323 is fixedly provided on the side of the connecting plate 32 away from the partition wall 2, and a positioning groove 311 adapted to the positioning block 323 is provided on the side of the mounting plate 31 away from the wall column 1.

[0042] Specifically, the cooperation between the positioning block 323 and the positioning groove 311 ensures precise alignment during installation, further improving installation efficiency. The positioning block 323 of the connecting plate 32 cooperates with the positioning groove 311 of the mounting plate 31 to achieve quick and precise alignment during installation, avoiding misalignment of the screw 322 during installation.

[0043] Furthermore, the partition wall 2 includes a concrete layer 21, and a fireproof layer 22 is fixedly connected to both the front and back sides of the concrete layer 21.

[0044] Specifically, the partition wall 2 is composed of a concrete layer 21 and fireproof layers 22 on both sides. The fireproof layer 22 effectively blocks high temperature and reduces the strength reduction of the concrete layer 21 caused by high temperature.

[0045] Furthermore, the spraying assembly 4 also includes a mounting block 44 rotatably connected to the mounting bracket 41, and the nozzle 43 is mounted on the lower end of the mounting block 44.

[0046] Specifically, by setting the mounting block 44 to be rotatably connected to the mounting bracket 41, the spray direction of the nozzle 43 can be adjusted, so that the spray range can be dynamically adjusted, thereby enhancing the flexibility and coverage effect of the cooling system.

[0047] Furthermore, the spraying assembly 4 also includes a fixing frame 45, a rotating shaft, and blades 46. The output end of the nozzle 43 is fixedly connected to the fixing frame 45. A rotating hole is provided at the bottom of the fixing frame 45. One end of the rotating shaft is fixedly connected to the blades 46, and the other end of the rotating shaft is rotatably connected to the rotating hole.

[0048] Specifically, an external water source supplies water to the nozzle 43 through the water pipe 42. When the water flows out from the nozzle 43, it drives the blade 46 to rotate around the pivot, expanding the spray range of the water. The mounting block 44 can rotate around the mounting frame 41, so that the spray angle of the nozzle 43 can be adjusted according to the direction of the fire, ensuring that the surface of the partition wall 2 is cooled evenly. The water pipe 42 exchanges heat with the concrete layer 21 through the pipe wall inside the partition wall 2, which helps to reduce the temperature of the partition wall 2. The dual cooling mechanism effectively prevents the partition wall 2 from burning through or collapsing due to high temperature, and continues to play its role in fireproof separation.

[0049] Furthermore, hoisting assemblies 5 are installed on both the front and back of the partition wall 2.

[0050] Furthermore, the hoisting assembly 5 includes a support rod 51 and a lifting ring 52. The support rod 51 passes through the partition wall 2 and is fixedly connected to the partition wall 2. Lifting rings 52 are fixedly provided at both ends of the support rod 51.

[0051] Specifically, the fixed lifting ring 52 is suitable for long-term fixed installation scenarios, and its structure is simple and reliable.

[0052] Furthermore, the hoisting assembly 5 includes a support rod 51, a bolt 53, and a lifting ring 52. The support rod 51 passes through the partition wall 2 and is fixedly connected to the partition wall 2. The bolt 53 is fixedly connected to the lifting ring 52 and threadedly connected to the support rod 51. Both ends of the support rod 51 are fixedly provided with lifting rings 52 by bolts 53.

[0053] Specifically, the bolt 53 connection method allows the lifting ring 52 to be disassembled when hoisting is not required, thus preventing the exposed lifting ring 52 from interfering with the operation of the fireproof structure.

[0054] Furthermore, a washer 324 is provided between the countersunk hole 321 and the screw 322, and the washer 324 is sleeved on the screw 322.

[0055] Specifically, the washer 324 inside the countersunk hole 321 increases the friction between the screw 322 and the connecting plate 32, preventing the screw 322 from loosening due to vibration and ensuring the long-term stability of the fixing assembly 3.

[0056] Installation steps: First, use the hoisting assembly 5 to align the positioning block 323 of the partition wall 2 with the positioning groove 311 and lower it, so that the countersunk hole 321 on the connecting plate 32 is aligned with the threaded groove on the mounting plate 31. Then, screw 322 through the countersunk hole 321 and screw it into the threaded groove, so that the connecting plate 32 fits tightly against the mounting plate 31, thereby firmly fixing the partition wall 2 between the two wall columns 1. This detachable connection greatly reduces maintenance costs and difficulties and improves the maintainability of the facility.

[0057] Working principle: When a fire occurs, an external water source supplies water to the nozzle 43 through the water pipe 42. When the water flows out from the nozzle 43, it pushes the blade 46 to rotate around the pivot, expanding the spray range of the water. According to the range of the fire, the mounting block 44 rotates around the mounting frame 41, so that the spray angle of the nozzle 43 can be adjusted according to the direction of the fire, ensuring that the surface of the partition wall 2 is cooled evenly. The water pipe 42 exchanges heat with the concrete layer 21 through the pipe wall inside the partition wall 2, which helps to reduce the temperature of the partition wall 2. The dual cooling mechanism effectively prevents the partition wall 2 from burning through or collapsing due to high temperature, and continues to play its role in fireproof separation.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
