Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of pressure vessels, in particular to a self-noise-reducing pressure vessel. BACKGROUND
[0002] In many industrial fields such as chemical industry, energy industry, pharmaceutical industry, etc., pressure vessels, as key equipment, bear multiple important functions such as storage, transportation and reaction, and are widely used and indispensable. With the continuous expansion of industrial production scale and the increasing complexity of production process, the performance requirements for pressure vessels are becoming increasingly stringent. Among them, the noise problem generated by pressure vessels during operation, as well as the stability of equipment operation, gas treatment effect, etc., have gradually become key factors restricting the further development of the industry.
[0003] In the traditional pressure vessel, during the gas inlet process, the gas usually directly enters the inside of the vessel, and the concentrated gas flow impacts the inner wall or internal components of the vessel, which will generate strong impact noise. Especially in the case of large gas flow, this impact noise is more significant, causing serious interference to the working environment, and long-term exposure to high noise environment will also affect the physical and mental health of workers. When the gas flows rapidly in the pressure vessel, due to the lack of effective buffering and regulating devices, the excessive speed of the gas flow will cause the gas to rub against the inner wall of the vessel and the internal pipeline, etc., thereby generating high-frequency noise. This noise not only has a large volume, but also has a wide range of propagation, which is difficult to effectively control through conventional sound insulation measures. During the gas discharge process of the pressure vessel, the gas is discharged at high speed from the inside of the vessel, which will also generate a large noise. Especially in some process flows that require frequent gas discharge, the gas discharge noise will exist continuously, further exacerbating the noise pollution of the working environment.
[0004] The traditional pressure vessel lacks effective filtering devices during gas inlet, resulting in dust and particulate matter carried by the gas directly entering the inside of the vessel. These impurities not only pollute the medium inside the vessel, affecting product quality, but also can deposit in the inner wall and pipeline of the vessel, reducing the flow efficiency of the gas, increasing the running resistance of the equipment, and even causing equipment failure. Although some pressure vessels are equipped with filtering devices, the dust and particulate matter accumulated in the filter cover are difficult to clean. Due to the unreasonable structure design of the filtering device, multiple components need to be disassembled during cleaning, which is cumbersome and time-consuming, and the filtering device cannot be cleaned in time, affecting its filtering effect and service life.
[0005] Traditional pressure vessels suffer from inadequate support structure design, resulting in insufficient stability of the vessel body. During operation, factors such as gas pressure and airflow impact can easily cause the vessel body to sway and vibrate, affecting not only normal operation but also potentially shortening its lifespan. Internal components, such as storage tanks, are prone to movement under external forces like airflow impacts. Traditional designs lack effective buffering and repositioning devices; displacement of the storage tank can disrupt gas flow, affecting normal equipment operation and even causing safety accidents. Furthermore, the inflexible connection methods between internal pipes and components make them susceptible to loosening or breakage during component movement, further compromising the stability and reliability of the equipment. Summary of the Invention
[0006] To address the aforementioned problems, this invention proposes a self-noise-reducing pressure vessel, which more precisely solves the problems mentioned in the background section.
[0007] This invention is achieved through the following technical solution: This invention proposes a self-noise-reducing pressure vessel, comprising a vessel body, an air inlet on one side of the vessel body, and an air outlet on the other side of the vessel body. The air inlet is used to deliver gas into the vessel body for storage, and the air outlet is used to discharge gas from the vessel body. The air inlet includes an air inlet pipe with a valve located on the side of the vessel body. A temporary storage cylinder is disposed inside the vessel body, and a sealing plate is installed on the inner wall of the temporary storage cylinder. The sealing plate has multiple holes, and a diverter pipe is inserted into each hole to guide the air inlet pipe to the temporary storage cylinder. The internal gas is diverted to reduce noise when the gas flow is too large. A scraper is installed on the inner wall of the diversion pipe to block the inside of the diversion pipe and buffer the airflow after it enters, thereby reducing the noise caused by excessive airflow speed. A flow-slowing section is provided on the side of the sealing plate located in the air inlet pipe. The flow-slowing section is used to buffer the airflow that is guided from the air inlet pipe to the temporary storage cylinder and to counteract the airflow speed. An ash discharge pipe is installed at the bottom of the temporary storage cylinder for the discharge of gas. A support frame is installed on the surface of the container body to support the container body.
[0008] Preferably, the scraping part includes a connecting spring installed on the inner wall of the temporary storage cylinder, and a scraper is installed at the end of the connecting spring. The scraper is inserted into the diversion pipe to counteract the gas velocity and clean the inner wall of the diversion pipe. A telescopic rod is installed between the temporary storage cylinder and the scraper, and the telescopic rod is used to limit the movement of the scraper.
[0009] Preferably, the sealing plate is provided in two places and a rubber sleeve is installed at each hole. The rubber sleeve is used to provide elastic support for the diversion pipe and to reduce noise when the gas comes into contact with its inner wall.
[0010] Preferably, the flow-retarding section includes a support spring installed on one side of the sealing plate, the end of the support spring is equipped with a conical head, the conical head is made of sound-absorbing material, and a telescopic cylinder is installed between the conical head and the sealing plate, the telescopic cylinder being used to limit the direction of force movement of the conical head.
[0011] Preferably, a filter cover is installed on the inner wall of the container body, and the ash discharge pipe is connected to the filter cover to block dust and particulate matter in the gas. An ash discharge pipe with a valve is installed at the bottom of the filter cover and extends to the outside of the container body to discharge dust and particulate matter.
[0012] Preferably, the temporary storage cylinder is located at the axial position of the container body, and a connecting hose is installed between the temporary storage cylinder and the air inlet pipe. The connecting hose is used to ensure the continuity between the air inlet pipe and the temporary storage cylinder when the temporary storage cylinder moves. A suspension part is installed on the inner wall of the container body. The suspension part is arranged in a circumferential array around the temporary storage cylinder. The suspension part is used to support and reset the temporary storage cylinder.
[0013] Preferably, the suspension part includes a connecting plate one installed on the inner wall of the container body and a connecting plate two installed on the surface of the temporary storage cylinder, and a suspension spring is installed between the connecting plate one and the connecting plate two.
[0014] Preferably, the gas outlet includes a gas collection hood installed on one side of the container body, and a gas outlet pipe with a valve is installed on the side of the gas collection hood. The gas outlet pipe is used to discharge the gas inside the container body.
[0015] Preferably, an installation sleeve is installed on the inner wall of the container body on one side of the gas outlet pipe, and a gas guide pipe is installed on one side of the installation sleeve to guide the gas into the installation sleeve.

[0016] Compared with the prior art, the present invention provides a self-noise-reducing pressure vessel, which has the following beneficial effects: This self-noise-reducing pressure vessel employs multiple noise reduction structures, including a diversion pipe, scraper, flow buffer, rubber sleeve, a cone-shaped head made of sound-absorbing material, and a through-hole plate. By addressing aspects such as gas diversion, buffering airflow speed, and noise absorption, it comprehensively reduces the noise generated by airflow impact or excessive flow velocity during the process of gas entering, storing, and discharging from the main body of the vessel, thereby improving the environmental noise during the operation of the pressure vessel.
[0017] This self-noise-reducing pressure vessel uses a filter hood to block dust and particulate matter in the gas entering the vessel body, ensuring the cleanliness of the discharged gas. The ash discharge pipe can promptly discharge the dust and particulate matter accumulated in the filter hood, ensuring the filtration effect of the filter hood and the normal operation of the pressure vessel. The connecting hose ensures that the inlet pipe and the temporary storage cylinder are always connected when the temporary storage cylinder moves, without affecting the normal gas delivery.
[0018] This self-noise-reducing pressure vessel uses a support frame to provide stable support for the main body of the vessel. When the temporary storage cylinder is moved by external forces such as airflow impact, the suspension part uses the elastic deformation of the suspension spring to buffer the movement and reset the temporary storage cylinder after the external force disappears, ensuring the stability of the temporary storage cylinder during operation, thereby ensuring the normal operation and noise reduction effect of the entire pressure vessel.

[0021] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Example
[0022] like Figures 1-6 As shown in the figure, an embodiment of the present invention discloses a self-noise-reducing pressure vessel, comprising a container body 1, an air inlet 2 on one side of the container body 1, and an air outlet 3 on the other side. The air inlet pipe 21 of the air inlet 2, equipped with a valve, is located on the side of the container body 1 and is used to deliver gas into the container body 1 for storage. A temporary storage cylinder 22 is provided inside the container body 1. A sealing plate 23 is installed on the inner wall of the temporary storage cylinder 22. The sealing plate 23 has multiple holes, into which diversion pipes 24 are inserted. The diversion pipes 24 divert the gas from the air inlet pipe 21 into the temporary storage cylinder 22. When the gas flow rate is too high, the gas is diverted by the diversion pipes 24, effectively reducing the noise generated by the concentrated impact of the airflow. A scraper 25 is installed on the inner wall of the diversion pipe 24. The scraper 25 seals the inside of the diversion pipe 24. When airflow enters, the scraper 25 buffers the airflow, reducing the noise generated by excessively high airflow velocity. A flow-damping section 5 is provided on one side of the inlet pipe 21 on the sealing plate 23. The flow-damping section 5 buffers the airflow from the inlet pipe 21 to the temporary storage cylinder 22, offsetting part of the airflow velocity and further reducing noise. An ash discharge pipe 26 is installed at the bottom of the temporary storage cylinder 22 for discharging gas. A support frame 11 is installed on the surface of the container body 1, which provides stable support for the container body 1 and ensures the stability of the pressure vessel during operation.
[0023] In this invention, the scraping section 25 includes a connecting spring 251 installed on the inner wall of the temporary storage cylinder 22, and a scraper 252 is installed at the end of the connecting spring 251. The scraper 252 is inserted into the diversion pipe 24. When gas enters the diversion pipe 24, the airflow impacts the scraper 252, causing the connecting spring 251 to undergo elastic deformation, which counteracts the gas velocity and reduces the gas flow rate, thereby reducing the noise caused by excessive airflow speed. At the same time, the scraper 252 can clean the inner wall of the diversion pipe 24 during its movement, preventing dust and other impurities from adhering to the inner wall and affecting gas flow and noise reduction effect.
[0024] In this invention, the sealing plate 23 is provided in two locations, and rubber sleeves 231 are installed at each opening. When the diversion pipe 24 is inserted into the rubber sleeve 231, the rubber sleeve 231 provides elastic support for the diversion pipe 24. During gas flow, when the gas comes into contact with the inner wall of the diversion pipe 24 and the rubber sleeve 231, the elasticity of the rubber sleeve 231 can buffer the gas impact force, effectively reducing the noise generated when the gas comes into contact with the inner wall. At the same time, the elasticity of the rubber sleeve 231 can also adapt to the minor vibrations of the diversion pipe 24 caused by airflow and other factors.
[0025] In this invention, the flow-damping section 5 includes a support spring 51 mounted on one side of the sealing plate 23. A conical head 52 is mounted on the end of the support spring 51, and the conical head 52 is made of sound-absorbing material. A telescopic cylinder 53 is installed between the conical head 52 and the sealing plate 23. When the airflow from the intake pipe 21 impacts the conical head 52, the support spring 51 undergoes elastic deformation, and the telescopic cylinder 53 restricts the conical head 52 to move only in the direction of force, thus counteracting and buffering the airflow velocity. Simultaneously, the sound-absorbing material of the conical head 52 absorbs some of the noise generated by the airflow, further reducing the noise when the airflow enters the temporary storage cylinder 22.
[0026] In this invention, a filter cover 6 is installed on the inner wall of the container body 1, and an ash discharge pipe 26 leads into the filter cover 6. When gas enters the container body 1, the filter cover 6 blocks dust and particulate matter in the gas, allowing relatively clean gas to be discharged or further processed. An ash discharge pipe 61 with a valve is installed at the bottom of the filter cover 6, and the ash discharge pipe 61 extends to the outside of the container body 1. When a certain amount of dust and particulate matter accumulates inside the filter cover 6, the valve of the ash discharge pipe 61 is opened to discharge the dust and particulate matter from the container body 1, ensuring the filtration effect of the filter cover 6 and the normal operation of the pressure vessel.
[0027] In this invention, a temporary storage cylinder 22 is positioned at the axial center of the container body 1, and a connecting hose 27 is installed between the temporary storage cylinder 22 and the air inlet pipe 21. When the temporary storage cylinder 22 moves due to factors such as airflow impact, the connecting hose 27 can undergo elastic deformation to ensure that the air inlet pipe 21 and the temporary storage cylinder 22 remain connected, without affecting the normal gas delivery. A suspension part 4 is installed on the inner wall of the container body 1, and the suspension part 4 is arranged in a circumferential array around the temporary storage cylinder 22. The suspension part 4 provides support for the temporary storage cylinder 22, and when the temporary storage cylinder 22 moves, the suspension part 4 can reset it, ensuring the stability of the temporary storage cylinder 22 during operation.
[0028] In this invention, the suspension part 4 includes a connecting plate 41 installed on the inner wall of the container body 1 and a connecting plate 42 installed on the surface of the temporary storage cylinder 22. A suspension spring 43 is installed between the connecting plate 41 and the connecting plate 42. When the temporary storage cylinder 22 moves due to external forces such as airflow impact, the suspension spring 43 undergoes elastic deformation, which buffers the temporary storage cylinder 22. At the same time, when the external force disappears, the elastic force of the suspension spring 43 can reset the temporary storage cylinder 22, ensuring the stability of the position of the temporary storage cylinder 22 during operation, thereby ensuring the normal operation of the entire pressure vessel and the noise reduction effect.
[0029] In this invention, the gas outlet 3 includes a gas collection hood 31 installed on one side of the container body 1, and a gas outlet pipe 32 with a valve installed on the side of the gas collection hood 31. When it is necessary to discharge the gas inside the container body 1, the valve of the gas outlet pipe 32 is opened, and the gas is collected by the gas collection hood 31 and discharged from the gas outlet pipe 32, realizing the orderly discharge of gas and facilitating subsequent processing or utilization of the gas.
[0030] In this invention, an installation sleeve 33 is installed on the inner wall of the container body 1 on one side of the outlet pipe 32. A gas guide pipe 34 is installed on one side of the installation sleeve 33, guiding the gas into the installation sleeve 33. The installation sleeve 33 and the gas collection hood 31 are connected. Multiple perforated plates 35 made of sound-absorbing material are provided on the inner wall of the installation sleeve 33, with the holes in the perforated plates 35 arranged in an alternating pattern. When gas enters the installation sleeve 33 from the gas guide pipe 34, the gas flows between the perforated plates 35. Due to the alternating arrangement of the holes, the gas flow path becomes complex. Simultaneously, the sound-absorbing perforated plates 35 can absorb some of the noise generated by the gas flow, effectively reducing the noise caused by excessive flow velocity during gas discharge and improving the environmental noise during the operation of the pressure vessel.
[0031] The working principle of this invention is as follows: The operator opens the valve on the air inlet pipe 21 of the air inlet section 2, allowing external gas to enter the pressure vessel. Gas is transported into the container body 1 through the air inlet pipe 21. Since the air inlet pipe 21 and the temporary storage cylinder 22 are connected by a connecting hose 27, the gas enters the temporary storage cylinder 22 through the connecting hose 27. The connecting hose 27 can elastically deform, ensuring that even if the temporary storage cylinder 22 moves due to airflow impact or other factors, the air inlet pipe 21 and the temporary storage cylinder 22 remain connected, without affecting normal gas delivery. The gas entering the temporary storage cylinder 22 impacts the sealing plate 23. The sealing plate 23 has multiple holes, and rubber sleeves 231 are installed at the holes. The diversion pipe 24 is inserted into the rubber sleeves 231, which provide elastic support for the diversion pipe 24. The gas is diverted through the diversion pipe 24. When the gas flow rate is too large, diversion can effectively reduce the noise generated by concentrated airflow impact. Meanwhile, when the gas comes into contact with the inner wall of the diversion pipe 24 and the rubber sleeve 231, the elasticity of the rubber sleeve 231 buffers the gas impact force, further reducing the noise generated when the gas comes into contact with the inner wall, and can adapt to the slight vibration of the diversion pipe 24 caused by airflow and other factors. A scraper part 25 is installed on the inner wall of the diversion pipe 24. One end of the connecting spring 251 of the scraper part 25 is installed on the inner wall of the temporary storage cylinder 22, and the other end is installed with a scraper 252, which is inserted into the diversion pipe 24. When the gas enters the diversion pipe 24, the airflow impacts the scraper 252, and the connecting spring 251 undergoes elastic deformation, which counteracts the gas velocity, reduces the gas flow rate, and reduces the noise generated by excessive airflow velocity. The telescopic rod 253 installed between the temporary storage cylinder 22 and the scraper 252 is used to limit the movement of the scraper 252. At the same time, the scraper 252 can clean the inner wall of the diversion pipe 24 during movement, preventing dust and other impurities from adhering to the inner wall and affecting gas flow and noise reduction effect. A flow-damping section 5 is provided on one side of the air intake pipe 21, with one end of the support spring 51 of the flow-damping section 5 mounted on one side of the sealing plate 23 and the other end fitted with a conical head 52. The conical head 52 is made of sound-absorbing material, and a telescopic cylinder 53 is installed between the conical head 52 and the sealing plate 23. When the airflow from the air intake pipe 21 impacts the conical head 52, the support spring 51 undergoes elastic deformation, and the telescopic cylinder 53 restricts the conical head 52 to move only in the direction of force, thus counteracting and buffering the airflow velocity. At the same time, the sound-absorbing material of the conical head 52 can absorb some of the noise generated by the airflow, further reducing the noise when the airflow enters the temporary storage cylinder 22. The temporary storage cylinder 22 is located at the axial position of the container body 1, and the suspension parts 4 on the inner wall of the container body 1 are arranged in a circumferential array around the temporary storage cylinder 22, providing support for the temporary storage cylinder 22. The first connecting plate 41 of the suspension part 4 is installed on the inner wall of the container body 1, the second connecting plate 42 is installed on the surface of the temporary storage cylinder 22, and the suspension spring 43 is installed between the first connecting plate 41 and the second connecting plate 42.When the temporary storage cylinder 22 moves due to external forces such as airflow impact, the suspension spring 43 undergoes elastic deformation, buffering the temporary storage cylinder 22. Simultaneously, when the external force disappears, the elastic force of the suspension spring 43 allows the temporary storage cylinder 22 to return to its original position, ensuring the stability of the temporary storage cylinder 22 during operation. A filter cover 6 is installed on the inner wall of the container body 1, and the ash discharge pipe 26 leads into the filter cover 6. When gas enters the container body 1, the filter cover 6 blocks dust and particulate matter in the gas, leaving relatively clean gas inside the container or preparing it for further processing. As gas continues to enter and be filtered, a certain amount of dust and particulate matter gradually accumulates inside the filter cover 6. An ash discharge pipe 61 with a valve is installed at the bottom of the filter cover 6, extending to the outside of the container body 1. When the accumulated dust and particulate matter inside the filter cover 6 reaches a certain level, the operator opens the valve of the ash discharge pipe 61 to discharge the dust and particulate matter from the container body 1, ensuring the filtration effect of the filter cover 6 and the normal operation of the pressure vessel. When it is necessary to discharge gas from the container body 1, the operator opens the valve on the gas outlet pipe 32 of the gas outlet section 3. The gas is collected by the gas collection hood 31 and discharged from the gas outlet pipe 32. An installation sleeve 33 is installed on the inner wall of the container body 1 on one side of the gas outlet pipe 32, and a guide pipe 34 is installed on one side of the installation sleeve 33. The guide pipe 34 guides the gas into the installation sleeve 33, and the installation sleeve 33 and the gas collection hood 31 are connected. Multiple perforated plates 35 made of sound-absorbing material are provided on the inner wall of the installation sleeve 33, and the holes in the perforated plates 35 are staggered. When the gas enters the installation sleeve 33 from the guide pipe 34, the gas flows between the perforated plates 35. Due to the staggered arrangement of the holes, the gas flow path becomes complex. At the same time, the perforated plates 35 made of sound-absorbing material can absorb some of the noise generated by the gas flow, effectively reducing the noise generated by excessive flow velocity when the gas is discharged, realizing the orderly discharge of gas, and facilitating subsequent treatment or utilization of the gas. Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
