Description

Technical Field

[0001] The invention relates to the technical field of inflatable cabinets, in particular to an environmentally friendly inflatable cabinet with rear gas outlet. Background Art

[0002] An environmentally friendly gas filling cabinet is a device used in power systems to reduce the impact on the environment, especially in the selection of insulating media. Environmentally friendly gas filling cabinets usually adopt a modular design to facilitate installation and maintenance. They have a compact structure and small size, making them suitable for use in limited spaces. The equipment adopts a fully sealed structure to ensure the stability and safety of the internal gas. The design of the sealed gas box can effectively prevent gas leakage. Using environmentally friendly gas as the insulating medium can reduce pollution to the environment and meet the requirements of green environmental protection.

[0003] At present, a Chinese invention patent application with publication date of October 21, 2022 and publication number CN 114709745B proposes a metal stamping equipment, including a shell, one end of which is fixedly connected to a sealing plate, and a pressure relief port is opened at the top of the sealing plate, and an upper cover is slidably connected to the top of the shell, and limiting plates are fixedly connected to both sides of the bottom end of the upper cover, and a first threaded rod is rotatably connected to the inside of the shell. The present invention adopts an "L"-shaped pressure relief channel, which is connected to the pressure relief valve at the bottom of the gas filling cabinet through the pressure relief port at one end. When the gas filling cabinet is short-circuited and high-temperature and high-pressure gas is accumulated inside, it can be discharged into the interior of the device through the pressure relief valve, and the pressure relief is completed by opening the slidable upper cover at the upper end of the device. At the same time as the pressure relief, the high-pressure gas can be used to provide power to spray the moisture inside the water tank on one side into the interior of the shell, and the evaporation reaction with the high-temperature gas reduces the temperature of the gas, so that the gas can be effectively cooled when discharged.

[0004] However, inflatable cabinets usually use sulfur hexafluoride as the insulating medium. Sulfur hexafluoride is a potent greenhouse gas with an extremely high global warming potential of 23,500 times that of carbon dioxide. Once leaked into the atmosphere, it will significantly aggravate the greenhouse effect. SF6 has a lifespan of up to 3,200 years in the atmosphere, which will have a long-term impact on the environment. At the same time, the leaked gas may pose a safety threat to operators, especially in closed or poorly ventilated environments. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to reduce the impact of hydrogen hexafluoride gas on the environment and workers during the pressure relief process of the inflatable cabinet, the embodiments of the present application provide the following solution.

[0026] Please also read Figures 1 to 6 An embodiment of the present application provides an environmentally friendly inflatable cabinet with rear air outlet, which includes an inflatable cabinet body 1, a cable chamber 2, an inflatable chamber 3, a reaction mechanism 4, a cooling mechanism 5 and an absorption component 6. The cable chamber 2 is arranged on the inflatable cabinet body 1, the inflatable chamber 3 is arranged on the inflatable cabinet body 1, the cooling mechanism 5 is arranged on the inflatable cabinet body 1, the absorption component 6 is arranged on the inflatable cabinet body 1, and the reaction mechanism 4 is arranged on the inflatable cabinet body 1.

[0027] In some embodiments, please refer to Figures 1 to 4 The inflatable cabinet body 1 is provided with a pressure relief assembly 8, and the pressure relief assembly 8 includes a pressure gauge 81, a pressure relief valve 82 and a pressure relief pipe 83. The pressure relief pipe 83 is provided on the inflatable cabinet body 1. A connecting port is opened on the inflatable cabinet body 1. The pressure gauge 81 is arranged on the pressure relief pipe 83 through the connecting port, and the pressure relief valve 82 is arranged on the pressure relief pipe 83.

[0028] In this arrangement, the pressure gauge 81 is used to monitor the pressure conditions inside the gas cabinet in real time. Through the pressure gauge 81, the operator can understand the pressure status inside the cabinet at any time to ensure that it is within a safe range. The pressure relief valve 82 is a safety device. When the pressure inside the gas cabinet exceeds the set value, the pressure relief valve 82 will automatically open to release excess gas or pressure to prevent the cabinet from exploding or being damaged due to excessive pressure. The pressure relief pipe 83 is a channel connecting the pressure gauge 81 and the pressure relief valve 82. It not only provides a measuring point for the pressure gauge 81, but also provides a safe discharge path for the pressure relief valve 82 to ensure that the released gas or pressure can be safely discharged from the cabinet. When the gas in the gas cabinet exceeds the set value, the pressure relief valve 82 opens to allow the gas to be safely discharged from the cabinet through the pressure relief pipe 83. The connecting port is an interface for installing the pressure gauge 81 and the pressure relief valve 82. It ensures that these components can be firmly installed on the gas cabinet body 1 and maintain good sealing to prevent gas leakage. The main function of the pressure relief assembly 8 is to improve the safety of the gas cabinet. Through real-time monitoring and automatic pressure relief, it can effectively prevent explosions or damage caused by excessive pressure and protect the safety of personnel and equipment. The combined use of the pressure gauge 81 and the pressure relief valve 82 ensures the reliability of the gas cabinet under various working conditions. Even in the case of abnormal pressure, the pressure relief assembly 8 can respond quickly to avoid accidents. The design of the pressure relief assembly 8 usually takes into account easy maintenance and replacement. The pressure gauge 81 and the pressure relief valve 82 can be easily checked and replaced through the connection port, reducing maintenance time and cost. By effectively controlling the internal pressure, the pressure relief assembly 8 can reduce the mechanical stress of the gas cabinet and extend the service life of the equipment. The operator can intuitively understand the status of the gas cabinet through the pressure gauge 81 and take corresponding measures as needed. This intuitive operation method improves work efficiency.

[0029] In some embodiments, please refer to Figures 1 to 4 A water tank assembly 7 is provided on the inflatable cabinet main body 1, and the water tank assembly 7 includes a connecting cover 72, a box body 73 and a water outlet pipe 74. The box body 73 is provided on the inflatable cabinet main body 1, and a connecting hole is provided on one end of the box body 73 away from the inflatable cabinet main body 1. The connecting cover 72 is provided on the box body 73 through the connecting hole. A water outlet hole is provided on one end of the box body 73 close to the inflatable cabinet main body 1. A through hole is provided on the inflatable cabinet main body 1 corresponding to the water outlet hole, and the water outlet pipe 74 is provided on the box body 73 through the water outlet hole and the through hole.

[0030] With such arrangement, after sulfur hexafluoride enters the pressure relief chamber, sulfur hexafluoride needs to react with water under high temperature to generate sulfur dioxide and hydrogen fluoride. The connecting cover 72 is installed on the box body 73 through the connecting hole to seal the box body 73 to prevent liquid leakage. When the liquid in the box body 73 is insufficient, the operator opens the water tank through the connecting cover 72 to add liquid. After sulfur hexafluoride enters the pressure relief chamber, the connecting pipe at the bottom of the box body 73 is opened to start draining water. Under high temperature conditions, water turns into water vapor after a period of time and reacts with sulfur hexafluoride. The water tank assembly 7 is sealed on the inflation cabinet body 1 through the connecting cover 72, and the box body 73 stores liquid. The design of the connecting cover 72 makes the water tank assembly 7 easy to open and close, which is convenient for filling, discharging and cleaning of liquid, and the maintenance personnel can easily inspect and maintain the water tank assembly 7.

[0031] In some embodiments, please refer to Figures 1 to 5 The reaction mechanism 4 includes an air suction component 41 and a power component 42. The air suction component 41 includes a heat collecting tube 411, a heat collecting ring 412, an expansion airbag 413, an airbag bottom plate 418, a fixing plate 417, a heat insulating plate 414 and a catalyst column 415. The fixing plate 417 is arranged on the inflatable cabinet body 1, the heat collecting tube 411 is arranged on the fixing plate 417, the heat collecting ring 412 is arranged on the heat collecting tube 411, the expansion airbag 413 is arranged on one end of the fixing plate 417 away from the heat collecting tube 411, the airbag bottom plate 418 is arranged on one end of the expansion airbag 413 away from the fixing plate 417, the heat insulating plate 414 is arranged on the fixing plate 417, and the catalyst column 415 is arranged on the airbag bottom plate 41 8 is located on one end close to the inflatable airbag 413, the catalyst column 415 is metal oxide alumina, the power assembly 42 includes a cylinder 421, a spring 422 and a connecting plate 423, the connecting plate 423 is arranged on the inflatable cabinet body 1, the cylinder 421 is arranged on one end of the connecting plate 423 close to the airbag bottom plate 418, the output shaft of the cylinder 421 is arranged on the airbag bottom plate 418, the spring 422 is sleeved on the cylinder 421, one end of the spring 422 is arranged on the connecting plate 423, and the other end of the spring 422 abuts against the airbag bottom plate 418, a baffle 419 is arranged on the fixing plate 417, and a heating plate 416 is arranged on one end of the airbag bottom plate 418 away from the spring 422.

[0032] With such arrangement, when the inflatable cabinet is accidentally depressurized, the gas enters the depressurization chamber, the cylinder 421 starts to operate, stretching the airbag bottom plate 418, and the airbag bottom plate 418 drives the expansion airbag 413 to start expanding, expanding the internal volume of the expansion airbag 413, and absorbing the gas into the expansion airbag 413. At the same time, the baffle plate 419 is arranged on the fixed plate 417 to reduce the probability of the gas directly entering the cooling assembly. The temperature of the gas is high when it is just absorbed into the expansion airbag 413, and the heating plate 416 starts to heat up and reacts with the catalyst column 415 on the airbag bottom plate 418. The catalyst column 415 breaks the chemical bond of sulfur hexafluoride, and under the action of the catalyst, reacts with water vapor in the air to reduce the direct discharge of sulfur hexafluoride into the environment and the impact on the environment. The main function of the heat collecting tube 411 and the heat collecting ring 412 is to collect and concentrate heat. The heat collecting tube 411 is usually made of a material with good thermal conductivity and can effectively absorb heat from the surrounding environment or a specific heat source. The heat collecting ring 412 further enhances the heat concentration and transfer efficiency. When the heat collected by the heat collecting tube 411 and the heat collecting ring 412 is transferred to the airbag, the gas in the airbag expands due to the heat, causing the volume of the airbag to increase. The catalyst column 415 is made of metal oxide alumina. Alumina has excellent catalytic properties and can accelerate certain chemical reactions, especially under high temperature conditions. This helps to improve the reaction efficiency. When the airbag expands, the piston of the cylinder 421 is pushed by the pressure of the airbag bottom plate 418, thereby generating mechanical movement. The function of the spring 422 is to buffer the impact force generated when the airbag expands and contracts, and protect the cylinder 421 and other components. The baffle 419 is set on the fixed plate 417 to control the flow path and speed of the airflow. It can adjust the expansion speed and pressure of the airbag, thereby optimizing the performance of the entire system. The heating plate 416 is used to provide additional heat, which helps to quickly heat the gas in the airbag when needed and increase the reaction speed. Through the design of the heat collecting tube 411 and the heat collecting ring 412, the system can effectively collect and utilize thermal energy and reduce energy loss. The design of the spring 422 and the baffle 419 makes the mechanical output of the cylinder 421 more stable, reduces impact and vibration, and extends the service life of the equipment. The use of metal oxide alumina as the catalyst column 415 can accelerate chemical reactions under high temperature conditions and improve reaction efficiency.

[0033] In some embodiments, please refer to Figures 1 to 6 The cooling mechanism 5 includes a heat sink 51 and a circulating fan assembly 52. ​​The heat sink 51 is arranged on the main body 1 of the inflatable cabinet. The circulating fan assembly 52 includes a motor 521 and a fan fin 522. The motor 521 is arranged on the main body 1 of the inflatable cabinet. The heat sink 51 is arranged on the motor 521. The heat sink 51 is coaxially driven with the output shaft of the motor 521. The heat sink 51 is a metal oxide alumina.

[0034] With such arrangement, after the sulfur hexafluoride is converted in the reaction mechanism 4, the output shaft of the cylinder 421 pushes the airbag bottom plate 418 to compress and expand the airbag 413, thereby pushing the completely reacted gas out of the expansion airbag 413, and then the gas enters the heat dissipation mechanism from above, passes through the heat sink 51, and the heat sink 51 is composed of the metal oxide aluminum oxide, so that the incompletely converted gas is continuously converted through the heat sink 51, and the gas enters the circulating fan assembly 52, and the motor 521 drives the fan blade 522 to rotate, thereby lowering the ambient temperature and reducing the volatilization of sulfur dioxide, thereby promoting further reaction of sulfur dioxide and hydrogen fluoride to meet the emission standards. The heat sink 51 can also absorb heat from the inside by contacting with the main body 1 of the inflatable cabinet. Due to the high thermal conductivity of aluminum oxide, the heat can be quickly transferred to the surface of the heat sink 51, and the rotation of the fan blade 522 generates a forced airflow, which accelerates the flow of air around the heat sink 51. This forced convection can significantly improve the heat dissipation efficiency, because the flowing air can take away the heat on the surface of the heat sink 51 more quickly. The heat sink 51 is made of alumina, a metal oxide with excellent thermal conductivity, and can quickly conduct heat from the inside of the gas cabinet to the surface of the heat sink 51. The circulating fan assembly 52 further enhances the heat dissipation effect through forced convection, so that the entire system can effectively reduce the internal temperature. The design of the motor 521 of the circulating fan assembly 52 usually takes energy saving into consideration, and can minimize energy consumption while providing sufficient airflow. The excellent thermal conductivity of the alumina heat sink 51 also reduces unnecessary energy loss. Through the coordinated work of the heat sink 51 and the circulating fan, the system can reduce the high temperature required for the reaction of sulfur hexafluoride and water vapor, maintain a stable temperature inside the gas cabinet, and prevent overheating, which is crucial for protecting internal electronic components and extending the life of the equipment.

[0035] In some embodiments, please refer to Figures 1 to 3 The absorption component 6 includes an absorption tank 61 and a filter plate 62. The absorption tank 61 is arranged on the inflation cabinet body 1, and the filter plate 62 is arranged on the connecting plate 423. A plurality of filter holes 63 are provided on the filter plate 62. A sodium hydroxide solution 64 is provided in the absorption tank 61. An air outlet is provided on the inflation cabinet body 1, and an air outlet pipe 9 is provided through the air outlet.

[0036] With such arrangement, after the gas is cooled by the fan sheet 522, the gas enters the absorption tank 61 through the filter holes 63 on the filter plate 62. The absorption tank 61 is provided with a sodium hydroxide solution 64. The sodium hydroxide solution 64 can absorb the sulfur dioxide and hydrogen fluoride gas present in the gas, and convert the gas into a gas that meets the emission standard and then discharge it from the gas outlet pipe 9. Sodium hydroxide is a strong alkali with a strong absorption capacity, especially for acidic gases such as sulfur dioxide and hydrogen fluoride. When the gas passes through the sodium hydroxide solution 64, sulfur dioxide and hydrogen fluoride will react chemically with the sodium hydroxide to generate harmless or low-harm compounds such as sodium sulfate and sodium fluoride, thereby effectively removing these harmful gases. The filter holes 63 on the filter plate 62 can intercept particulate matter and impurities in the gas to prevent these substances from entering the absorption tank 61, which not only protects the purity of the sodium hydroxide solution 64, but also prolongs the service life of the solution. The combination of the filter plate 62 and the absorption tank 61 forms a multi-stage purification process. The filter plate 62 removes particulate matter, and the absorption tank 61 removes harmful gases, ensuring that the final emitted gas meets environmental standards. Through the absorption of the sodium hydroxide solution 64, the system can effectively remove harmful gases such as sulfur dioxide and hydrogen fluoride, reducing pollution to the atmospheric environment. This is particularly important for the treatment of waste gas generated in the industrial production process, which helps companies meet the requirements of environmental protection regulations. Removing harmful gases not only helps protect the environment, but also protects equipment from corrosion and extends the service life of equipment. At the same time, reducing the emission of harmful gases also protects the health and safety of workers.

[0037] The implementation principle of the rear-venting environmentally friendly inflatable cabinet of the present application embodiment is as follows: the operator is aware of the pressure status in the cabinet at any time. When the gas in the inflatable cabinet exceeds the set value, the pressure relief valve 82 opens to allow the gas to be safely discharged from the cabinet through the pressure relief pipe 83 to prevent the cabinet from exploding or being damaged due to excessive pressure. After sulfur hexafluoride enters the pressure relief chamber, sulfur hexafluoride needs to react with water at high temperature to generate sulfur dioxide and hydrogen fluoride. The connecting cover 72 is installed on the box body 73 through the connecting hole to seal the box body 73 to prevent liquid leakage. When the liquid in the box body 73 is insufficient, the operator opens the connecting cover 72. Open the water tank and add liquid. After sulfur hexafluoride enters the pressure relief chamber, the connecting pipe at the bottom of the box body 73 is opened to start draining water. Under high temperature conditions, water turns into water vapor after a period of time and reacts with sulfur hexafluoride. When the inflatable cabinet accidentally releases pressure, gas enters the pressure relief chamber, and the cylinder 421 starts to operate, stretching the airbag bottom plate 418. The airbag bottom plate 418 drives the expansion airbag 413 to start expanding, expanding the internal volume of the expansion airbag 413, and absorbing the gas into the expansion airbag 413. At the same time, the baffle plate 419 is set on the fixed plate 417 to reduce the probability of gas directly entering the cooling component. The gas is just absorbed into the expansion airbag. The temperature of the inflatable airbag 413 is relatively high, and the heating plate 416 starts to heat up, and reacts with the catalyst column 415 on the airbag bottom plate 418. The catalyst column 415 breaks the chemical bond of sulfur hexafluoride, and reacts with water vapor in the air under the action of the catalyst, thereby reducing the direct discharge of sulfur hexafluoride into the environment and the impact on the environment. After the sulfur hexafluoride is converted in the reaction mechanism 4, the output shaft of the cylinder 421 pushes the airbag bottom plate 418 to compress the inflatable airbag 413, so that the reacted gas is pushed out of the inflatable airbag 413, and then the gas enters the heat dissipation mechanism from above, passes through the heat sink 51, and at the same time The heat sink 51 is made of the metal oxide aluminum oxide, so that the incompletely converted gas is continuously converted through the heat sink 51, and the gas enters the circulating fan assembly 52. ​​The motor 521 drives the fan blades 522 to rotate, thereby lowering the ambient temperature and reducing the volatilization of sulfur dioxide. After the gas is cooled by the fan blades 522, the gas enters the absorption tank 61 through the filter holes 63 on the filter plate 62. The absorption tank 61 is provided with a sodium hydroxide solution 64. The sodium hydroxide solution 64 can absorb the sulfur dioxide and hydrogen fluoride gas in the gas, and convert the gas into a gas that meets the emission standards and then discharge it from the outlet pipe 9.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
