Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal gas storage engineering, especially to a single-section rubber sealing gas holder reconstructed from a polygonal thin oil sealing gas holder. BACKGROUND

[0002] In the production and distribution process of metallurgy, petrochemical industry and city gas industry, many industrial gases and coal gas need to be stored. As an indispensable container, gas storage equipment plays a crucial role in these industries. The main purpose of building a gas holder is to recover the instantaneous gas emission caused by the imbalance of production in the enterprise by utilizing its characteristics of timely throughput, effectively buffering the frequent fluctuations that are difficult to adapt, and playing a role in making up for the shortage and reducing emission. The gas holder is not only used for urban civilian use to alleviate the tight situation of city gas supply, but also widely used in the production and construction of modern steel plants, playing an important role in low-carbon economy.

[0003] Traditional coal gas holders are divided into wet and dry structures. Because the wet coal gas holder has a large floor area, a short service life, and heavy maintenance work in use, and improper operation can cause derailment, roof collapse and other problems, it is gradually replaced by dry coal gas holders. The dry coal gas holder is mainly composed of a cylindrical outer cylinder of circular or polygonal shape, and a piston along the upper and lower cylinder wall, a bottom plate and a top plate. According to the sealing method between the piston and the cylinder wall, the dry coal gas holder can be divided into three forms of thin oil sealing, dry oil sealing and rubber membrane sealing. Since the 1980s, the regular polygonal thin oil sealing coal gas holder has been widely used in steel plant production. Special sealing oil is injected into the special sealing mechanism between the piston and the cylinder wall in the holder for sealing, and the piston runs along the straight guide rail in the holder to achieve the purpose of adjusting the gas storage capacity and pressure.

[0004] However, many existing polygonal thin oil sealing type coal gas holders have been in operation for more than 20 years, and there are problems of disrepair. Most of the existing polygonal thin oil sealing type coal gas holders are low-pressure holders (design pressure below 8kPa), and with the expansion of enterprise scale and the increase of pipeline pressure, these low-pressure gas holders cannot be operated in grid again. In addition, the polygonal thin oil sealing type coal gas holder adopts the piston sealing method of thin oil and steel slide plate, which requires high installation precision. Due to insufficient installation precision, many gas holders have problems such as piston guide wheel jamming and large oil leakage during operation. Even after major repair, these problems cannot be solved.

[0005] In comparison, the single-section rubber sealing type gas holder has the advantages of strong adaptability, large gas storage throughput, low operation cost and the like, and is the development trend of future gas holders. However, if the polygonal thin oil sealing type gas holder and its foundation are completely removed and reconstructed into the single-section rubber sealing type gas holder, not only the engineering time is long, but also the engineering cost is high. Meanwhile, since the polygonal thin oil sealing type gas holder is built earlier, the service life of the steel structure is 30 years, and the service life of the foundation concrete is 50 years, which makes more and more polygonal thin oil sealing type gas holders begin to consider reconstruction to achieve the purpose of reusing and saving cost. Therefore, how to fully utilize the foundation structure of the existing polygonal thin oil sealing type gas holder to reduce the reconstruction cost and shorten the construction period of the single-section rubber sealing type gas holder has become a technical problem to be solved at present.

[0039] Overall, as shown in the embodiments of Figure 1 、 Figure 2 And Figure 3 Single-section type rubber sealing gas cabinet by polygonal thin oil sealing gas cabinet reconstruction is reconstructed by using the structure of polygonal thin oil sealing base 110, polygonal thin oil sealing side plate 120 and polygonal thin oil sealing stand 130 of original polygonal thin oil sealing gas cabinet, which avoids high cost caused by overall demolition and reconstruction, saves a large amount of building materials and construction time, reduces waste production, and is more in line with environmental protection requirements.

[0040] And, single-section type rubber film sealing inner sleeve 200 and support structure 300 in the utility model are integrally arranged, and support structure 300 can be arranged between polygonal thin oil sealing cabinet body 100 and single-section type rubber film sealing inner sleeve 200, so that polygonal thin oil sealing cabinet body 100 and single-section type rubber film sealing inner sleeve 200 form a stable space stress system.

[0041] And, inner sleeve section 210 between adjacent two inner sleeve stands 220 and support structure 300 are preformed, so that they can be installed as a whole, making installation more convenient, reducing welding workload and construction difficulty, thereby speeding up construction progress and improving construction quality.

[0043] Compared with the existing polygonal thin oil sealing gas cabinet, the single-section rubber sealing gas cabinet after the transformation has the advantages of strong adaptability, large gas storage throughput, low operation cost and the like, and can utilize the structures of the original polygonal thin oil sealing gas cabinet, such as the concrete foundation, the steel structure column, the side wall plate, the cabinet top, the ring corridor and the elevator shaft, so that the scrapped polygonal thin oil sealing cabinet body 100 can continue to be put into use. The single-section rubber sealing gas cabinet after the transformation can better cope with the demand for enterprise scale expansion and pipeline pressure increase, prolongs the service life of the equipment, and improves the economic benefit of the enterprise.

[0044] In the embodiments of the utility model, as shown in the embodiments shown in Figure 4 and Figure 5 , along the height direction, the inner sleeve section 210 includes a plurality of inner sleeve side plates 211 connected in sequence, and the two sides of the inner sleeve side plate 211 are sealingly connected with the inner sleeve column 220.

[0045] By connecting the plurality of inner sleeve side plates 211 in sequence, the inner sleeve section 210 forms a whole structure, which is conducive to accelerating the installation efficiency of the inner sleeve section 210. By adjusting the number of inner sleeve side plates 211, the height of the single-section rubber sealing gas cabinet can be flexibly adjusted according to actual needs, so as to better meet the gas storage demand in different application scenarios.

[0046] In addition, by sealingly connecting the inner sleeve side plate 211 with the inner sleeve column 220, a continuous whole structure is formed, which enhances the rigidity and stability of the single-section rubber film sealing inner sleeve 200 in the height direction. Even in the case of high pressure or large capacity gas storage, the safety and stability of the single-section rubber film sealing inner sleeve 200 can be ensured.

[0047] The designer can adjust the connection mode between the plurality of inner sleeve side plates 211 and the connection mode between the inner sleeve side plate 211 and the inner sleeve column 220 according to the use needs, which is not specifically limited here. Preferably, the plurality of inner sleeve side plates 211 are connected by welding, and the inner sleeve side plate 211 and the inner sleeve column 220 are connected by welding.

[0048] In the embodiments of the utility model, as shown in the embodiments shown in Figure 4 and Figure 5 , the support structure 300 includes an inner sleeve transverse partition plate 310 arranged on each inner sleeve side plate 211, and the inner sleeve transverse partition plate 310 sealingly connects the inner sleeve side plate 211 and the polygonal thin oil sealing cabinet body 100.

[0049] By setting the inner sleeve transverse plate 310 on the inner sleeve side plate 211 and the polygonal thin oil sealing cabinet body 100, the inner sleeve transverse plate 310 not only enhances the rigidity of the inner sleeve side plate 211 as the support structure 300, but also forms a whole stable stress system through the sealing connection with the polygonal thin oil sealing cabinet body 100, effectively preventing the deformation and displacement of the single-section rubber membrane sealing inner sleeve 200, and ensuring the safety and stability of the whole single-section rubber sealing gas cabinet.

[0050] In addition, the pressure on the single-section rubber membrane sealing inner sleeve 200 can be uniformly conducted to the polygonal thin oil sealing cabinet body 100 through the inner sleeve transverse plate 310, avoiding local stress concentration, helping to prolong the service life of the single-section rubber sealing gas cabinet, and reducing the risk of structural damage caused by excessive stress. Designers can adjust the specific structure of the inner sleeve transverse plate 310 according to the needs, which is not limited here.

[0051] In the embodiment of the utility model, as shown in the example, Figure 5 One end of the inner sleeve side plate 211 is cold-bent and formed into the inner sleeve transverse plate 310 towards the polygonal thin oil sealing cabinet body 100.

[0052] By directly forming the inner sleeve transverse plate 310 by cold-bending one end of the inner sleeve side plate 211, the inner sleeve side plate 211 and the inner sleeve transverse plate 310 become a whole structure, which helps to enhance the rigidity and stability of the single-section rubber membrane sealing inner sleeve 200, and reduces the welding workload and construction difficulty, improving the construction efficiency.

[0053] In addition, the inner sleeve transverse plate 310 and the inner sleeve side plate 211 can be seamlessly connected, effectively preventing gas leakage and having better safety and reliability.

[0054] Designers can adjust the cold-bending method of the inner sleeve side plate 211 according to the needs, which is not limited here. Preferably, the inner sleeve side plate 211 is perpendicular to the corresponding inner sleeve transverse plate 310.

[0055] By arranging the inner sleeve side plate 211 and the inner sleeve transverse plate 310 vertically, the inner sleeve side plate 211 and the inner sleeve transverse plate 310 form a stable rectangular frame structure, enhancing the rigidity of the whole structure. In addition, this vertical layout makes the stress in all directions uniformly transmitted and distributed, avoiding local stress concentration, thereby improving the stability and safety of the single-section rubber sealing gas cabinet under high pressure or large capacity gas storage conditions. In addition, the vertically arranged inner sleeve side plate 211 and inner sleeve transverse plate 310 make the installation process more simple and fast, reducing the welding workload and construction difficulty.

[0056] Of course, in other feasible embodiments, the designer can adjust the bending angle between the inner sleeve side plate 211 and the inner sleeve transverse plate 310 according to the use needs, and no specific numerical limitation is made here.

[0057] In the embodiment of the utility model, as shown in the embodiment shown by the figure, Figure 5 The inner sleeve transverse plate 310 is welded with the adjacent inner sleeve side plate 211. Specifically, the inner sleeve transverse plate 310 forms a horizontal end face after cold bending, and the other end of the adjacent inner sleeve side plate 211 can be lapped on the horizontal end face and welded with the inner sleeve transverse plate 310 to be fixed.

[0058] By welding the inner sleeve transverse plate 310 with the adjacent inner sleeve side plate 211, they form a whole structure, which greatly enhances the overall rigidity and stability of the single-section rubber sealing gas tank. Moreover, the welding connection not only improves the strength of the structure, but also ensures the safety and reliability under the condition of high pressure or large capacity gas storage.

[0059] Moreover, by making the inner sleeve transverse plate 310 constitute a horizontal end face, the inner sleeve side plate 211 can be placed more stably on the inner sleeve transverse plate 310, and the positioning accuracy between the inner sleeve transverse plate 310 and the inner sleeve side plate 211 is ensured, which is conducive to improving the production efficiency.

[0060] Further, a positioning structure can be arranged between the adjacent inner sleeve transverse plate 310 and the inner sleeve side plate 211, and the positioning efficiency between the adjacent inner sleeve transverse plate 310 and the inner sleeve side plate 211 is accelerated by using the positioning structure. The designer can adjust the specific structure of the positioning structure according to the use needs, and no specific limitation is made here. For example, the positioning structure includes positioning blocks and positioning grooves arranged on the adjacent inner sleeve transverse plate 310 and the inner sleeve side plate 211 respectively.

[0061] In the embodiment of the utility model, as shown in the embodiment shown by the figure, Figure 4 And Figure 5 The inner sleeve column 220 includes an inner sleeve T-shaped column, the inner sleeve T-shaped column includes an end plate and a web, the end plate is connected with the adjacent inner sleeve side plate 211 respectively, and the web extends to the polygonal thin oil sealing tank body 100 and is connected with the polygonal thin oil sealing column 130.

[0062] The end plate of the inner sleeve T-shaped column can firmly connect the adjacent inner sleeve side plate 211, forming a stable frame structure. At the same time, the web of the inner sleeve T-shaped column extends and connects with the polygonal thin oil sealing column 130, further enhancing the overall rigidity and stability of the single-section rubber membrane sealing inner sleeve 200.

[0063] The designer can adjust the specific shape and structure of the inner sleeve T-shaped column according to the use requirement, which is not specifically limited here. For example, the inner sleeve T-shaped column is welded by two steel plates. Alternatively, the inner sleeve T-shaped column is formed by a T-shaped steel.

[0064] In the embodiment of the utility model, as shown in the example, Figure 2 The inner wall of the inner sleeve side plate 211 is arc-shaped along the circumference of the polygonal thin oil sealing cabinet body 100. By making the inner wall of the inner sleeve side plate 211 arc-shaped, the cross section of the single-section rubber film sealing inner sleeve 200 is circular or approximately circular when the plurality of inner sleeve side plates 211 and the inner sleeve upright column 220 are connected.

[0065] By cooperating with the plurality of inner sleeve side plates 211, the single-section rubber film sealing inner sleeve 200 forms a structure similar to a cylinder, which is beneficial to improve the structural strength and stability of the single-section rubber film sealing inner sleeve 200, so that the single-section rubber film sealing inner sleeve 200 can better resist the change of external pressure and internal gas pressure. Compared with the polygonal structure, the circular structure can more evenly distribute stress and avoid stress concentration, thereby prolonging the service life of the single-section rubber sealing gas cabinet.

[0066] In the embodiment of the utility model, as shown in the example, Figure 1 The single-section rubber film sealing gas cabinet converted from the polygonal thin oil sealing gas cabinet further comprises a single-section rubber film sealing gas cabinet piston assembly 400 arranged in the single-section rubber film sealing inner sleeve 200.

[0067] Specifically, the piston assembly 400 of the single-section rubber film sealing gas cabinet comprises a piston support 410 arranged in the single-section rubber film sealing inner sleeve 200 and a single-section rubber film sealing gas cabinet piston slidably arranged in the single-section rubber film sealing inner sleeve 200.

[0068] The designer can adjust the specific structure of the piston support 410 and the single-section rubber film sealing gas cabinet piston according to the use requirement, which is not specifically limited here. In addition, the designer can adjust the rubber sealing structure of the single-section rubber film sealing gas cabinet according to the use requirement, which is not specifically limited here.
