Abstract
Description
Technical Field
[0001] This invention relates to the field of purification and disinfection technology, and in particular to a multi-technology synergistic purification and disinfection device. Background Technology
[0002] Purification and disinfection equipment is mainly used in enclosed and semi-enclosed spaces. By integrating multiple purification and disinfection technologies, it removes gaseous pollutants such as PM2.5, formaldehyde, and benzene compounds from the air, while killing bacteria and viruses, decomposing odors, and filtering dust mites and pet dander. It significantly improves indoor air quality, protects human health, and is widely applicable to homes, offices, hospitals, schools, hotels, car interiors, and airplane cabins.
[0003] The purification and disinfection equipment used in vehicle interiors and cabins has its air inlet fixedly connected to the cabin's return pipe via a flange, and its air outlet connected to the cabin's air conditioning duct. The cabin's air conditioning duct is equipped with a structure to stabilize the positive pressure of the airflow, ensuring that the purified airflow returns stably to the passenger cabin. However, when the vehicle interior and cabin encounter unavoidable vibrations and bumps, the purification and disinfection equipment will shake synchronously with the vehicle, causing severe airflow turbulence inside the equipment. If the air inlet remains unchanged, the turbulent airflow will enter the equipment with unstable speed and direction, which will not only disrupt the stable working flow field of the purification and disinfection module and reduce the time for air to be purified and disinfected inside the equipment, but also continuously impact the precision components inside the equipment, easily causing fatigue damage to the components and shortening the service life of the equipment. Summary of the Invention
[0004] The purpose of this invention is to provide a multi-technology collaborative purification and disinfection device that can solve the problems in the prior art where the purification and disinfection device moves synchronously with the aircraft when the aircraft encounters turbulence, affecting the air disinfection effect, and where there are problems such as loose flanges and increased gaps at the air inlet connection.
[0005] The technical problem to be solved by this invention can be achieved through the following technical solution: A multi-technology synergistic purification and disinfection device includes a purification shell and a partition plate 1 welded to its internal center line. The inner cavity of the purification shell is divided into a disinfection space and a purification space by the partition plate 1. A partition plate 2 is welded to the middle of the purification space. The purification space is divided into an optimization chamber and a degradation chamber from top to bottom by the partition plate 2. An air inlet pipe is connected to the side wall of the purification shell near the degradation chamber by a flange. An air outlet pipe is connected to the side wall of the purification shell near the optimization chamber. An air inlet is opened on the inner wall of the air inlet pipe opposite to the purification shell. An annular airbag is embedded in the annular inner wall of the air inlet, and a mounting groove 1 for accommodating the annular airbag is opened in the air inlet. Annularly distributed pressurized airbags are embedded in the inner wall of the flange ring at the connection between the purification housing and the air inlet pipe, and a mounting groove 2 for accommodating the pressurized airbags is opened on the flange ring of the purification housing. The mounting groove 2 is arranged opposite to the flange ring on the air inlet pipe. A co-pipe connecting the pressurized airbags and the annular airbags is embedded in the purification housing.
[0006] Furthermore, an air outlet is provided on the inner wall of the purification housing corresponding to the air outlet pipe.
[0007] Furthermore, an air pump is fixedly installed on the outer wall of the purification housing. The output end of the air pump is connected to an air supply pipe. The output end of the air supply pipe extends into the purification housing and is connected to the annular airbag. The input end of the air pump is connected to an air delivery pipe. The input end of the air delivery pipe extends into the air outlet and is connected to the air outlet.
[0008] Furthermore, the purification housing has a main vent pipe on its inner wall between the air inlet and the air outlet, which is connected to the annular airbag. The output end of the main vent pipe is connected to the air outlet, and a control valve is installed on the inner wall of the main vent pipe near the annular airbag.
[0009] Furthermore, the output end of the main vent pipe is oriented in the same direction as the airflow direction at the outlet.
[0010] Furthermore, the purification housing has an annular groove and a blowing ring groove on the flange ring at the air inlet. The annular groove and the blowing ring groove are connected, and the output end of the blowing ring groove is set towards the gap between the mounting groove and the air inlet flange ring. The inner wall of the purification housing has a side vent pipe for connecting the annular groove and the main vent pipe.
[0011] Furthermore, the opening of the air-blowing ring groove gradually decreases from the end closest to the annular groove to the end furthest from the annular groove.
[0012] Furthermore, a photocatalyst structure is vertically installed in the center of the disinfection space, and ultraviolet lamps are symmetrically installed on both sides of the photocatalyst structure in the disinfection space. A negative ion generator is provided in the optimization chamber, and a plasma generator is provided in the degradation chamber.
[0013] Furthermore, an intake fan is fixedly installed on the inner wall of the purification housing at the output end of the air inlet, and an exhaust fan is fixedly installed on the inner wall of the purification housing at the input end of the air outlet.
[0014] Furthermore, an inertial sensor is installed on the top of the purification housing. The inertial sensor is used to collect turbulence data during aircraft flight and is electrically connected to the aircraft's environmental control system.
[0015] The beneficial effects of this invention are: 1. In the present invention, when encountering turbulence in the aircraft, by reducing the diameter of the air inlet and the effective flow area, the instantaneous excessive air volume can be limited, which can avoid flow field turbulence, ensure the duration and effect of air purification and disinfection, and at the same time prevent airflow from impacting the internal purification module, reduce vibration impact, and extend the service life of the equipment. In addition, during the inflation of the annular airbag, the pressurized airbag is simultaneously inflated and pressurizes and tightens the air inlet pipe flange ring, which enhances the firmness of the air inlet pipe connection, reduces the loosening of the air inlet pipe flange and the increase of gap, avoids the leakage of unpurified air, and further ensures the overall purification effect of the equipment.
[0016] 2. In this invention, the control valve is opened through the aircraft environmental control system. The gas inside the annular airbag and the pressurized airbag is mainly discharged through the main vent pipe, and part of it is discharged through the side vent pipe. The gas entering the side vent pipe is pressurized and discharged through the annular groove and the blowing ring groove in sequence. The gap between the flange of the air inlet pipe and the flange of the purification shell is blown to avoid dirt and bacteria from accumulating in the connection gap, generating odors and increasing the purification and disinfection load of the equipment.
[0017] 3. This invention adopts a filterless three-stage purification and disinfection chain. Through the preliminary degradation by plasma, the deep disinfection by ultraviolet light and photocatalysis, and the optimization of air quality by negative ions, multiple technologies work together to achieve high purification efficiency for particulate matter, gaseous pollutants and microorganisms, avoiding filter clogging, bacterial growth and secondary pollution, and reducing maintenance and use costs.

Detailed Implementation
[0026] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0027] Example 1: Please refer to Figures 1-7 As shown, in the existing technology, when an aircraft encounters turbulence, the purification and disinfection equipment moves synchronously with the aircraft, which in turn causes severe airflow disturbance inside the equipment, affecting the air purification and disinfection effect. The vibration generated by the aircraft turbulence mainly acts on the flange connection between the air inlet and the lower return pipe, causing the flange connection to loosen and the gap to increase. The following solutions can be used to solve this problem. This embodiment of a multi-technology collaborative purification and disinfection device includes a purification shell 1 and a partition plate 2 welded to its internal center line. The inner cavity of the purification shell 1 is divided into a disinfection space and a purification space by the partition plate 2. A partition plate 9 is welded to the middle of the purification space. The purification space is divided into an optimization chamber and a degradation chamber from top to bottom by the partition plate 9. An air inlet pipe 4 is connected to the side wall of the purification shell 1 near the degradation chamber by a flange. An air outlet pipe 3 is connected to the side wall of the purification shell 1 near the optimization chamber. An air inlet is opened on the inner wall of the air inlet pipe 4 opposite to the inner wall of the purification shell 1. An annular airbag 11 is embedded in the inner wall of the air inlet, and a mounting groove 1 for accommodating the annular airbag 11 is provided inside the air inlet. Annularly distributed pressurized airbags 16 are embedded in the inner wall of the flange ring at the connection between the purification housing 1 and the air inlet pipe 4, and a mounting groove 2 for accommodating the pressurized airbags 16 is provided on the flange ring of the purification housing 1. The mounting groove 2 is positioned opposite to the flange ring on the air inlet pipe 4. A connecting pipe 15 is embedded inside the purification housing 1, connecting the pressurized airbags 16 and the annular airbags 11. A mounting groove 3 for accommodating the connecting pipe 15 is provided inside the purification housing 1.
[0028] Please see Figure 2 As shown, an air outlet is provided on the inner wall of the purification housing 1 corresponding to the air outlet pipe 3.
[0029] Please see Figures 1-7As shown, an air pump 21 is fixedly installed on the outer wall of the purification housing 1. The output end of the air pump 21 is connected to an air supply pipe 22. The output end of the air supply pipe 22 extends into the purification housing 1 and is connected to the annular airbag 11. The input end of the air pump 21 is connected to an air delivery pipe 23. The input end of the air delivery pipe 23 extends into the air outlet and is connected to the air outlet.
[0030] Please see Figures 2-4 As shown, the purification housing 1 has a main vent pipe 12 on its inner wall between the air inlet and the air outlet, which communicates with the annular airbag 11. The output end of the main vent pipe 12 is connected to the air outlet. A control valve 13 is installed on the inner wall of the main vent pipe 12 near the annular airbag 11. The control valve 13 is electrically connected to the aircraft environmental control system.
[0031] Please see Figures 2-4 As shown, the output end of the main vent pipe 12 faces the same direction as the airflow direction at the outlet. This avoids disrupting the smooth flow of airflow at the outlet.
[0032] Please see Figure 2 As shown, a photocatalytic structure 6 is vertically installed in the middle of the disinfection space, and ultraviolet lamps 5 are symmetrically installed on both sides of the photocatalytic structure 6. A negative ion generator 7 is installed in the optimization chamber, and a plasma generator 8 is installed in the degradation chamber; the air arrows point to the direction of air flow. To further clarify the above: Air enters the device through the cabin's return pipe and the device's intake pipe 4. The plasma generator 8 first performs preliminary degradation of pollutants in the air. The air then enters the stainless steel inner liner containing the built-in ultraviolet lamps 5 and photocatalytic structure 6 for deep disinfection and catalytic decomposition. Finally, the negative ion generator 7 optimizes the air quality before the air enters the cabin's air conditioning duct for complete purification. This device does not rely on traditional filters, achieving a synergistic effect of multiple technologies, resulting in high purification and disinfection efficiency. By constructing an orderly three-level purification and disinfection chain, it achieves efficient removal of particulate matter, gaseous pollutants, and microorganisms from the air, while reducing operating costs and avoiding secondary pollution.
[0033] The instruction manual is needed because photocatalysts, also known as photocatalysts, are a general term for semiconductor materials with photocatalytic functions, represented by nano-sized titanium dioxide. Titanium dioxide is a representative photocatalytic material; it can produce strongly oxidizing substances (such as hydroxyl radicals and oxygen) under light irradiation and can be used to decompose organic compounds, some inorganic compounds, bacteria, and viruses. In daily life, photocatalysts can effectively degrade toxic and harmful gases in the air, such as formaldehyde, thus efficiently purifying the air; they can also be used to purify water resources.
[0034] Please see Figures 2-4As shown, an intake fan 32 is fixedly installed on the inner wall of the purification housing 1 at the output end of the air inlet, and an exhaust fan 31 is fixedly installed on the inner wall of the purification housing 1 at the input end of the air outlet. Air is introduced into the interior of the device through the intake fan 32, and air is drawn out of the interior of the device through the exhaust fan 31.
[0035] Please see Figures 1-7 As shown, an inertial sensor 10 is installed on the top of the purification housing 1. The inertial sensor 10 is used to collect turbulence data during the flight of the aircraft. The inertial sensor 10 is electrically connected to the aircraft environmental control system. Turbulence data represents the vibration acceleration value of the purification housing 1 during aircraft flight. When the vibration acceleration value is greater than the preset vibration acceleration threshold, it indicates that the purification housing 1 experiences significant turbulence with the aircraft, meaning there is a risk of loosening in the flange connection structure between the purification housing 1 and the air intake pipe 4. Furthermore, the larger the turbulence data, the more unstable the operating state of the purification housing 1, thus affecting the air purification and disinfection function. In this case, an adjustment signal is generated and sent to the aircraft environmental control system. Upon receiving the adjustment signal, the aircraft environmental control system immediately controls the air pump 21 to operate. When the vibration acceleration value is less than or equal to the preset vibration acceleration threshold, it indicates that the phenomenon of the purification housing 1 experiencing turbulence with the aircraft is not significant, and no signal is generated.
[0036] When generating the adjustment signal: the air pump 21 is controlled to work, and the purified and disinfected air at the air outlet is transmitted to the air supply pipe 22 through the air supply pipe 23. Then, the annular air bag 11 is inflated through the air supply pipe 22. After inflation, the annular air bag 11 forms a state where the diameter gradually decreases from the end near the air inlet pipe 4 to the end away from the air inlet pipe 4. This reduces the diameter of the air inlet, reduces the effective flow area, limits the instantaneous excessive air volume, avoids flow field turbulence, ensures the duration of air purification and disinfection, and guarantees the air purification effect. It also prevents the instantaneous excessive air volume from impacting the internal purification module, while reducing vibration and impact, and extending the service life of the equipment.
[0037] Simultaneously, while the annular airbag 11 is being inflated, the pressurized airbag 16 is also inflated through the air pipe 15. The inflated pressurized airbag 16 pressurizes the flange ring on the air inlet pipe 4, strengthens the connection of the air inlet pipe 4, reduces the risk of the flange at the air inlet becoming loose and the gap at the connection increasing, prevents unpurified air from leaking from the gap, and ensures the overall air purification effect of the equipment.
[0038] The beneficial effects of this embodiment are as follows: When encountering turbulence, by reducing the diameter of the air inlet and the effective flow area, the instantaneous excessive air volume can be limited, which can avoid flow field turbulence, ensure the duration and effect of air purification and disinfection, prevent airflow from impacting the internal purification module, reduce vibration impact, and extend the service life of the equipment. In addition, during the inflation of the annular airbag 11, the pressurized airbag 16 is simultaneously inflated and pressurizes and tightens the flange ring of the air inlet pipe 4, which enhances the firmness of the connection of the air inlet pipe 4, reduces the loosening of the flange of the air inlet pipe 4 and the increase of gap, avoids the leakage of unpurified air, and further ensures the overall purification effect of the equipment.
[0039] Example 2, please refer to Figures 2-4 As shown, the following solutions can be used to address the problem that dirt and bacteria can easily accumulate in the connection gap between the air inlet and the lower return pipe flange in the existing technology, resulting in odors and increased equipment purification and disinfection load; The purification housing 1 has an annular groove 17 and an air blowing ring groove 18 on the flange ring at the air inlet. The annular groove 17 and the air blowing ring groove 18 are connected, and the output end of the air blowing ring groove 18 is set towards the gap between the mounting groove 2 and the flange ring of the air inlet pipe 4. The inner wall of the purification housing 1 has a side vent pipe 14 for connecting the annular groove 17 and the main vent pipe 12.
[0040] Please see Figures 2-4 As shown, the air blowing ring groove 18 gradually decreases in size from one end near the annular groove 17 to the end away from the annular groove 17, which enhances the cleaning of the flange connection.
[0041] The beneficial effects and operating principle of this embodiment are as follows: When the aircraft is in a smooth state and no longer bumps, the control valve 13 is opened through the aircraft environmental control system. The gas inside the annular airbag 11 and the pressurized airbag 16 is mainly discharged through the main vent pipe 12, and part of it is discharged through the side vent pipe 14. The gas entering the side vent pipe 14 is pressurized and discharged through the annular groove 17 and the blowing ring groove 18 in sequence. The gap between the flange of the air inlet pipe 4 and the flange of the purification housing 1 is blown to avoid dirt and bacteria from accumulating in the connection gap, which would cause odor and increase the purification and disinfection load of the equipment.
[0042] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
