TECHNICAL FIELD

[0001] The present application relates to the technical field of gas storage tanks, in particular to a sound-attenuating exhaust device for a gas storage tank. BACKGROUND

[0002] The electrolytic plant gas storage tank is mainly used for storing compressed gas, such as air. In the event of unstable power grid, sudden increase in load, or sudden shutdown of generator set, the gas storage tank can release compressed air as backup energy in a very short time to ensure the stability and reliability of power supply. When the power load is small, the electrolytic plant can use the compressed air in the gas storage tank to improve the efficiency of the generator set and further optimize the utilization of power resources.

[0003] During the storage of gas in the gas storage tank, the gas will accumulate over time, and the internal pressure will gradually increase. If not regularly vented, it may cause the internal pressure of the gas storage tank to be too high, thereby causing safety problems such as failure of the safety valve or rupture of the gas storage tank. Therefore, regular venting is a necessary measure to ensure that the internal pressure of the gas storage tank remains within a safe range.

[0004] However, in the related art, the gas is directly discharged, and since the gas contains certain impurities, it is easy to cause environmental pollution. In addition, under the action of pressure, the impurities discharged with the gas also have the possibility of causing injury. In addition, the gas has a large noise when it is discharged, which affects the environment. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0031] In the related art, the gas is directly exhausted, and since the gas contains certain impurities, it is easy to cause environmental pollution. In addition, under the action of pressure, the impurities exhausted with the gas also have the possibility of hurting people. In addition, the gas has a large noise when it is exhausted, which affects the environment.

[0032] In order to solve the above technical problems, the present application provides a sound-attenuating exhaust device of a gas storage tank, which comprises a tank body 1, a cyclone separator 2, a sound-attenuating layer 3 and a sound-attenuating filter layer 4. The tank body 1 defines a cavity.

[0033] The cyclone separator 2 is arranged in the cavity and has an air inlet pipe 21, an air outlet pipe 22 and a dust exhaust pipe 23. The air outlet of the air outlet pipe 22 is located in the cavity. The sound-attenuating layer 3 is arranged between the outer wall of the cyclone separator 2 and the inner wall of the tank body 1. The sound-attenuating filter layer 4 is arranged at the air outlet of the air outlet pipe 22 to filter the gas passing through the air outlet. The side wall of the tank body 1 is provided with an air hole 1a communicating with the cavity, so as to discharge the filtered gas to the outside of the tank body 1.

[0034] The cyclone separator 2 is a commercially available product of the prior art, and its principle is roughly as follows: the gas enters the cyclone separator 2 along the tangential direction through the gas inlet pipe 21, and the gas moves downward in a spiral manner, so that solid particles (also referred to as impurities) with a larger inertia centrifugal force are thrown to the inner side wall of the cyclone separator 2, and fall to the dust discharge pipe 23 below under the action of gravity, while the lighter gas is discharged through the middle gas outlet pipe 22, thereby completing the solid-gas separation.

[0035] However, some small particles or impurities that are not completely separated due to certain reasons are discharged together with the purified gas, and the impurities are filtered again under the action of the sound-absorbing filter layer 4, and finally the gas is discharged through the air vent hole 1a at the upper end.

[0036] In the above process, the design of the sound-absorbing layer 3 effectively reduces the noise generated during the operation of the cyclone separator 2. The sound-absorbing layer 3 significantly reduces the propagation of noise by absorbing sound wave energy and changing the direction of sound wave propagation. The sound-absorbing filter layer 4 further filters the gas treated by the cyclone separator 2 at the gas outlet of the gas outlet pipe 22. This design not only ensures the purity of the gas, but also enhances the filtering effect of the system. At the same time, the sound-absorbing filter layer 4 itself also has a certain sound-absorbing effect, further reducing the noise of the system.

[0037] Please refer to Figure 1 , the cavity includes a first cavity 1b and a second cavity 1c, the cyclone separator 2 is arranged in the first cavity 1b, the sound-absorbing layer 3 is located in the first cavity 1b, the sound-absorbing filter layer 4 is located in the second cavity 1c, and the air vent hole 1a is in communication with the second cavity 1c. The second cavity 1c is vertically distributed with the first cavity 1b, wherein the second cavity 1c is located above the first cavity 1b, which conforms to the flow direction of the purified gas.

[0038] The sound-absorbing layer 3 is located in the first cavity 1b and adjacent to the cyclone separator 2, which can more effectively absorb the noise generated during the operation of the cyclone separator 2. At the same time, the space between the sound-absorbing layer 3 and the cyclone separator 2 is relatively closed, which helps to reduce the diffusion of noise and further improve the sound-absorbing effect.

[0039] The sound-absorbing filter layer 4 is located in the second cavity and connected to the gas outlet of the gas outlet pipe 22. This design ensures that the gas preliminarily treated by the cyclone separator 2 will not be disturbed by other factors before entering the sound-absorbing filter layer 3, thereby ensuring the stability of the filtering effect. At the same time, the relative independence of the second cavity 1c also helps to reduce the noise that may be generated during the filtering process.

[0040] The air vent hole 1a is in communication with the second cavity 1c, so that the gas treated by the sound-absorbing filter layer 4 can be smoothly discharged to the outside of the tank body 1. This design avoids the problem of poor ventilation caused by complex structure, ensuring the ventilation performance of the system.

[0041] Further, a partition plate 11 is arranged in the tank body 1. The partition plate 11 can be arranged horizontally or inclinedly relative to the horizontal plane. The partition plate 11 is fixed to the side wall of the tank body 1 by welding or screws, etc. The partition plate 11 divides the cavity into a first cavity 1b and a second cavity 1c. The partition plate 11 is provided with a through hole communicating the first cavity 1b and the second cavity 1c.

[0042] In this way, the sound-absorbing filter layer 4 and the sound-absorbing layer 3 are separated, and the gas discharged through the gas outlet pipe 22 enters the second cavity 1c through the through hole and can smoothly enter the sound-absorbing filter layer 4 for further filtering. This design ensures the continuity and efficiency of the filtering process, which helps to improve the filtering performance of the entire system.

[0043] Further, the plane where the gas outlet of the gas outlet pipe 22 is located is between the planes where the two ends of the through hole are opened. In this way, the path of the gas discharged from the gas outlet of the gas outlet pipe 22 is optimized, so that the gas blown out of the gas outlet of the gas outlet pipe 22 does not enter the first cavity 1b, and the gas flow enters the second cavity 1c more smoothly, reducing the possibility of turbulent flow, thereby improving the filtering effect and sound-absorbing performance.

[0044] On the other hand, the gas outlet of the gas outlet pipe 22 is located inside the through hole, so that a certain support structure is formed between the gas outlet pipe 22 and the partition plate 11. This design enhances the structural stability of the entire system and reduces the risk of loosening or damage of components caused by gas flow impact or other external factors.

[0045] After a long time of filtering, some impurities will be attached to the sound-absorbing filter layer 4, so the sound-absorbing filter layer 4 needs to be cleaned or replaced. The side wall of the tank body 1 is provided with an access opening (not shown in the figure) communicating with the second cavity 1c, which simplifies the process of inspection and maintenance and improves work efficiency.

[0046] Referring to Figure 2 , the sound-absorbing filter layer 4 includes a frame 41 and a body 42. The frame 41 defines a mounting cavity, and the mounting cavity forms an opening on the upper surface of the frame 41. The opening is arranged opposite to the air hole 1a. The bottom of the frame 41 is provided with a plurality of air vents. The body 42 is arranged in the mounting cavity.

[0047] By splitting the sound-absorbing filter layer 4 into the frame 41 and the body 42, a modular design is achieved. This design makes it more convenient to install and replace the sound-absorbing filter layer 4. When the sound-absorbing filter layer 4 needs to be replaced, the old body 42 can be removed from the frame 41, then a new body 42 is installed, and finally the frame is installed back in place.

[0048] It should be understood that, in order to avoid the body 42 from shaking, the body 42 is attached to the side wall of the mounting cavity formed by the frame 41.

[0049] The sound-absorbing filter layer 4 can be taken out through the maintenance opening. To facilitate taking out, the frame body 41 can be provided with a handle, thereby facilitating taking out of the frame body 41.

[0050] Referring to Figure 1 The plurality of air vents 1a are arranged at intervals, and each air vent 1a has a size less than a predetermined value, which can be flexibly selected according to actual needs, and the predetermined value is not limited. By arranging the plurality of air vents 1a, the ventilation area of the tank body to the outside can be significantly increased, thereby accelerating the flow speed of the gas and preventing the pressure in the tank body 1 from being too high, and ensuring the ventilation performance of the system.

[0051] In addition, the plurality of air vents 1a are arranged at intervals, so that the discharged gas can be more uniformly dispersed to the outside of the tank body 1, avoiding the situation that the local gas concentration is too high or too low. Such uniform gas distribution helps to improve the filtering effect and sound-absorbing performance, and ensures the stable operation of the entire system.

[0052] Referring to Figure 1 The electric control valve 231 is arranged in the cavity, so that the solid-gas separation of the cyclone separator 2 is mainly completed in the tank body 1, which can further reduce the noise.

[0053] The electric control valve 231 is electrically connected with an external controller. After completing the solid-gas separation, the electric control valve 231 can be remotely controlled to be opened, so as to discharge the particles accumulated at the bottom of the cyclone separator 2.

[0054] In the present application, the sound-absorbing layer 3 at least includes one of a porous sound-absorbing layer, a fiber layer and a sound insulation board layer. The porous sound-absorbing layer is polyurethane foam, the fiber layer can be natural plant fiber or inorganic mineral fiber, and the sound insulation board layer can be gypsum board, fiber board composed of wood fiber and adhesive, or polyurethane board, and can also be polyester fiber cotton, glass fiber cotton, rock wool, etc., or sound absorption board such as wood sound absorption board, foam sound absorption board, polyester fiber sound absorption board, etc.

[0055] It can be understood that the sound-absorbing layer 3 can be attached to the inner wall of the tank body 1, or can be directly arranged on the outer wall of the cyclone separator 2, or can be filled on the inner wall of the tank body 1 and the outer wall of the cyclone separator 2. The specific arrangement of the sound-absorbing layer 2 is not explained here.

[0056] It should be understood that the above-mentioned porous sound-absorbing layer, fiber layer and sound insulation board layer are widely used in places where sound insulation is required, and therefore will not be described here.

[0057] Further, the sound-absorbing filter layer 4 at least includes one of a porous dust absorption layer, a fiber sound absorption layer and a metal fiber layer.

[0058] The porous sound-absorbing layer has a large number of micro-pores inside, which can absorb sound waves and reduce noise. Common porous sound-absorbing layer materials include glass fiber, mineral wool, foam plastic, etc. They not only have good sound-absorbing performance, but also can filter out some impurity particles in the gas.

[0059] Fibrous sound-absorbing layers such as polyester fiber, glass fiber, etc. are also commonly used as acoustic filter materials. These materials have soft and fluffy properties, can effectively absorb sound waves, and to some extent, filter impurity particles in the gas,

[0060] Metal fiber layers such as metal mesh or metal fiber materials can block the passage of larger particles and absorb part of the sound waves through their structural properties.
