Description

Explosion-proof horizontal gas storage tank Technical Field

[0001] This utility model relates to the field of gas storage tank technology, specifically an explosion-proof horizontal gas storage tank. Background Technology

[0002] A gas storage tank is a device specifically designed to store gases. Generally, air storage tanks operate at temperatures between 0℃ and 100℃. During use, if the gas contains oil, the oil will enter the tank and form oil deposits. If this oil is not removed promptly, it will accumulate inside the tank over time and gradually carbonize under repeated exposure to high temperatures, forming carbon deposits. The presence of carbon deposits reduces the thermal conductivity of the tank, leading to localized temperature increases. When the carbon deposits reach a certain level, they can spontaneously combust due to high temperatures or sparks, potentially causing an explosion of the gas inside the tank.

[0003] Reference CN214037851U discloses an explosion-proof gas storage tank. One side of the tank body is fixedly connected to an exhaust pipe, and the other side is fixedly connected to an intake pipe. A second housing is fixedly installed inside the tank body, and the second housing is filled with coolant. Both the tank body and the second housing have pressure-reducing holes inside. The second housing is mounted on top of a buffer mechanism, which is installed on the bottom inner surface of the first housing. However, oil deposits may accumulate in the tank body, which cannot prevent spontaneous combustion and explosion caused by carbon buildup. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an explosion-proof horizontal gas storage tank that prevents oil from accumulating inside the tank to form carbon deposits, which could lead to local temperature rise and cause spontaneous combustion and explosion of the gas inside the tank.

[0005] To solve the above technical problems, this utility model provides an explosion-proof horizontal gas storage tank, including a tank body, an inlet pipe, and an exhaust pipe. A filter mechanism is provided on the inlet pipe. The filter mechanism includes a shell with an end cap, a filter frame sealed inside the shell, a honeycomb filter element fixedly mounted on the filter frame, a first sealing groove on the bottom surface of the end cap, and a second sealing groove on the top surface of the shell. The end cap and the shell are sealed together by a sealing strip I. An exhaust chamber is provided on the top surface of the tank body, an exhaust port is provided at the bottom of the exhaust chamber, an exhaust plug is provided in the exhaust port, a phenolic resin graphite ring is provided on the side of the exhaust plug, and the exhaust port and the exhaust plug are sealed by the phenolic resin graphite ring. A guide rod is provided on the exhaust plug, a spring is passed through the guide rod, and the guide rod extends out of the top surface of the exhaust chamber. An exhaust hole is provided on the top surface of the exhaust chamber.

[0006] By adopting the above technical solution, the exhaust port and exhaust plug of the exhaust chamber on the tank are sealed with a phenolic resin graphite ring. A filtration mechanism with a honeycomb filter element is installed on the air inlet pipe of the tank. This results in high oil collection efficiency and good filtration effect, preventing oil from accumulating inside the tank and forming carbon deposits, which could lead to localized temperature increases and cause spontaneous combustion and explosion of the gas inside the tank. Reduced carbon deposits effectively reduce the difficulty of cleaning and maintenance work inside the tank, reduce labor intensity, and improve the explosion-proof effect of the gas storage tank.

[0007] Preferably, the two outer sides of the filter frame, the bottom plate, and the inner wall of the housing are tightly fitted together, and the top surface is sealed and fitted to the inner side of the end cap.

[0008] By adopting the above technical solution, the side and bottom plates of the filter frame are tightly fitted to the inner wall of the housing, and the top surface is fitted and fixed to the inner side of the end cover, ensuring that air only passes through the filter element and does not leak from the side gaps. By eliminating bypass leakage, the filtration performance, system stability and safety reliability are comprehensively improved.

[0009] Preferably, the four end faces of the filter frame are provided with continuous sealing recesses, and sealing strips II are provided in the sealing recesses. The end caps and the top surface of the filter frame are sealed by sealing strips II.

[0010] By adopting the above technical solution, continuous sealing recesses are opened on the four end faces of the filter frame, which facilitates the installation of sealing strip II on the filter frame.

[0011] Preferably, the inner side and bottom of the housing are provided with continuous sealing recesses II, and the filter frame and the housing are also sealed and connected by sealing strip II.

[0012] By adopting the above technical solution, the two sealing grooves, sealing recess one and sealing recess two, of the filter frame and the shell form a double insurance structure. The sealing strip II is constrained by the groove walls on both sides, similar to the tenon and mortise interlocking. Even if the groove on one side undergoes a slight displacement due to vibration or thermal deformation, the other side can still maintain a seal, effectively improving the sealing effect.

[0013] Preferably, the size ratio between the inlet and outlet on the shell is 1:0.8 to 1:1.2.

[0014] By adopting the above technical solution, with an inlet-to-outlet size ratio of 0.8-1.2, uniform gas flow within the filtration mechanism is ensured, preventing localized excessively high or low flow velocities. If the inlet size is significantly larger than the outlet size, the gas will suddenly contract upon entering the filtration mechanism, causing a sharp increase in flow velocity. This can impact the honeycomb filter element, affecting filtration efficiency and filter lifespan. Conversely, if the inlet size is significantly smaller than the outlet size, gas flow within the filtration mechanism will be too slow, reducing filtration efficiency and potentially creating gas stagnation zones within the filtration mechanism, increasing pressure loss.

[0015] Preferably, the size ratio of the outlet of the filter mechanism to the inlet pipe of the air storage tank is 1:1 to 1:1.2.

[0016] By adopting the above technical solution, a size ratio of 1:1 to 1:1.2 between the outlet and inlet pipes ensures that gas can smoothly enter the storage tank from the filtration mechanism without causing additional pressure loss or leakage risks due to excessive size differences. In some systems with extremely high requirements for gas supply stability, such as storage tanks for pneumatic systems used in the precision electronics manufacturing industry, this ratio may need to be more precisely controlled at around 1 to ensure stable system operation.

[0017] Preferably, the inlet of the housing is located on the lower part of one side, and the outlet of the housing is located on the upper part of the opposite side.

[0018] By adopting the above technical solution, the inlet and outlet form diagonal flow channels, which can effectively disperse the inlet jet and avoid local high-speed zones.

[0019] Preferably, the horizontal distance between the inlet of the honeycomb filter element and the shell is ≥0.3 times the shell width, and the horizontal distance between the outlet of the honeycomb filter element and the shell is ≥0.25 times the shell width.

[0020] By adopting the above technical solution, the direct impact of the imported jet on the honeycomb filter element is avoided, which could lead to excessively high local flow velocity and damage to the filter material.

[0021] Preferably, the vertical distance between the inlet of the honeycomb filter element and the shell is 0.2-0.3 times the height of the shell, and the vertical distance between the outlet of the honeycomb filter element and the shell is 0.15-0.2 times the height of the shell.

[0022] By adopting the above technical solution, the vertical distance between the inlet and the shell is 0.2-0.3 times the shell height, and the distance between the outlet and the shell is 0.15-0.2 times the shell height. This ensures that the inlet jet is fully diffused in the vertical direction, reduces the pressure drop fluctuation of the honeycomb filter element, reduces the flow velocity gradient, and makes the gas form a uniform flow field in front of the honeycomb filter element, thereby improving the collection efficiency and filtration effect.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. This utility model features a phenolic resin graphite ring sealing the exhaust port and plug of the exhaust chamber on the tank body. A honeycomb filter element is installed on the air inlet pipe of the tank body, resulting in high oil collection efficiency and good filtration effect. This prevents oil from accumulating inside the tank and forming carbon deposits, which could lead to localized temperature increases and potentially cause spontaneous combustion and explosion of the gas inside the tank. Reduced carbon deposits effectively lower the difficulty of cleaning and maintenance work inside the tank, reduce labor intensity, and improve the explosion-proof performance of the gas storage tank.

[0025] 2. The exhaust port and the exhaust plug of this utility model are sealed by a phenolic resin graphite ring to ensure that gas will not leak during normal operation.

[0026] 3. The filter frame and the housing of this utility model form a double-safety structure with two sealing grooves: sealing groove one and sealing groove two. The sealing strip II is constrained by the groove walls on both sides, similar to a tenon and mortise interlocking. Even if one side of the groove body undergoes a slight displacement due to vibration or thermal deformation, the other side can still maintain a seal, thus improving the sealing effect.

[0032] As shown in Figure 1, the explosion-proof horizontal gas storage tank includes a tank body 1, and air inlet pipes 2 and exhaust pipes 3 on both sides of the tank body 1. A filter mechanism 4 is installed on the air inlet pipe 2, and the filter mechanism 4 includes a housing 5. An end cap 8 is sealed and installed on the housing 5, and a filter frame 6 is sealed and installed inside the housing 5. A honeycomb filter element 7 is fixedly installed on the filter frame 6. A first sealing groove 9 is provided on the bottom surface of the end cap 8, and a second sealing groove 10 is provided on the top surface of the housing 5. The end cap 8 and the housing 5 are sealed and connected by a sealing strip I11.

[0033] As shown in Figure 2, an exhaust chamber 12 is provided on the top surface of the tank 1, and an exhaust port 13 is provided at the bottom of the exhaust chamber 12. An exhaust plug 14 is provided in the exhaust port 13, and a phenolic resin graphite ring 15 is provided on the side of the exhaust plug 14. The exhaust port 13 and the exhaust plug 14 are sealed by the phenolic resin graphite ring 15 to ensure that gas does not leak during normal operation. A guide rod 16 is provided on the exhaust plug 14, and a spring 17 passes through the guide rod 16, which extends out of the top surface of the exhaust chamber 12; an exhaust hole 18 is opened on the top surface of the exhaust chamber 12. When the gas pressure inside the tank 1 is too high, the gas pressure overcomes the resistance of the spring 17 of the exhaust plug 14 and opens the exhaust plug 14. The gas is discharged from the exhaust port 13 through the exhaust hole 18, thereby reducing the gas pressure inside the tank 1 and preventing the tank 1 from exploding due to excessive pressure.

[0034] In this application, the exhaust port 13 and exhaust plug 14 of the exhaust chamber 12 on the tank body 1 are sealed by a phenolic resin graphite ring 15. A filter mechanism 4 with a honeycomb filter element 7 is installed on the air inlet pipe 2 of the tank body 1. This results in high oil collection efficiency and good filtration effect, preventing oil from accumulating inside the tank and forming carbon deposits, which could lead to local temperature increases and cause spontaneous combustion and explosion of the gas inside the tank. The reduction of carbon deposits effectively reduces the difficulty of cleaning and maintenance work inside the tank body 1, reduces labor intensity, and improves the explosion-proof effect of the gas storage tank.

[0035] As shown in Figure 3, the two outer sides of the filter frame 6, the bottom plate, and the inner wall of the housing 5 are tightly fitted together, and the top surface is sealed and fitted to the inner side of the end cap 8, ensuring that air only passes through the filter element and does not leak from the side gaps. By eliminating bypass leakage, the filtration performance, system stability, and safety reliability are comprehensively improved.

[0036] The four end faces of the filter frame 6 are provided with continuous sealing recesses 19 in the circumferential direction, and sealing strips II 23 are installed in the sealing recesses 19. The continuous sealing recesses 19 on the four end faces of the filter frame 6 facilitate the installation of square sealing strips II 23 on the filter frame 6.

[0037] The inner side and bottom surface of the housing 5 are provided with continuous sealing recesses 20. The filter frame 6 and the housing 5 are sealed together by sealing strip II 23. The two sealing grooves of the filter frame 6 and the housing 5, sealing recess 19 and sealing recess 20, form a double-safety structure. The sealing strip II 23 is constrained by the groove walls on both sides, similar to a tenon and mortise joint. Even if one side of the groove undergoes slight displacement due to vibration or thermal deformation, the other side can still maintain a seal, effectively improving the sealing effect. The end cap 8 also has a sealing recess to accommodate the sealing strip II 23, achieving a seal between the end cap 8 and the top surface of the filter frame 8.

[0038] As shown in Figure 4, the size ratio between the inlet 21 and the outlet 22 on the housing 5 is 1:0.8 to 1:1.2, ensuring uniform gas flow within the filter mechanism 4 and preventing localized excessively high or low flow velocities. If the inlet 21 is much larger than the outlet 22, the gas will suddenly contract upon entering the filter mechanism 4, causing a sharp increase in flow velocity, which will impact the honeycomb filter element 7, affecting the filtration effect and filter life. Conversely, if the inlet 21 is much smaller than the outlet 22, the gas flow within the filter mechanism 4 will be too slow, not only reducing filtration efficiency but also potentially creating gas stagnation areas within the filter mechanism 4, increasing pressure loss.

[0039] The size ratio of the outlet 22 of the filter mechanism 4 to the inlet pipe 2 of the gas storage tank is 1:1 to 1:1.2. This ensures that gas can smoothly enter the gas storage tank from the filter mechanism 4 without causing additional pressure loss or leakage risk due to excessive size difference. In some systems with extremely high requirements for gas supply stability, such as gas storage tanks used in pneumatic systems in the precision electronics manufacturing industry, this ratio may need to be more precisely controlled at around 1 to ensure stable system operation.

[0040] The inlet 21 of the casing 5 is located on the lower part of one side, and the outlet 22 of the casing 5 is located on the upper part of the opposite side. The inlet 21 and outlet 22 form a diagonal flow channel, which can effectively disperse the inlet jet and avoid local high-speed zones.

[0041] The horizontal distance between the honeycomb filter element 7 and the inlet 21 of the housing 5 is ≥0.3 times the width of the housing 5, and the horizontal distance between the honeycomb filter element 7 and the outlet 22 of the housing 5 is ≥0.25 times the width of the housing 5. For example, if the width of the housing 5 is 1m, then the distance between the inlets 21 is ≥0.3m, to avoid the jet from the inlet 21 directly impacting the honeycomb filter element 7, which could lead to excessively high local flow velocity and damage to the filter material.

[0042] The vertical distance between the honeycomb filter element 7 and the inlet 21 of the housing 5 is 0.2-0.3 times the height of the housing 5. For example, if the height of the housing 5 is 1.5m, the vertical distance is 0.3-0.45m. The vertical distance between the honeycomb filter element 7 and the outlet 22 of the housing 5 is 0.15-0.2 times the height of the housing 5. This ensures that the inlet jet is fully diffused in the vertical direction, reduces pressure drop fluctuations in the honeycomb filter element 7, reduces the velocity gradient, and allows the gas to form a uniform flow field in front of the honeycomb filter element 7, thereby improving the collection efficiency and filtration effect.

[0043] During normal operation, the gas entering the tank 1 from the inlet pipe 2 is first filtered through the honeycomb filter element 7 inside the filter mechanism 4 before being delivered into the tank 1. The exhaust port 13 and the exhaust plug 14 are sealed by a phenolic resin graphite ring 15, preventing gas leakage. When the gas pressure inside the tank 1 becomes too high, the gas pressure overcomes the resistance of the spring 17 of the exhaust plug 14, opening the exhaust plug 14. The gas then exits from the exhaust port 13 through the exhaust hole 18, reducing the gas pressure inside the tank 1 and preventing an explosion due to excessive pressure. After the oil in the gas is filtered, it prevents oil from accumulating inside the tank and forming carbon deposits, which could lead to localized temperature increases and spontaneous combustion or explosion of the gas inside the tank, thus improving the explosion-proof effect of the gas storage tank.
