Description

TECHNICAL FIELD The present disclosure relates to the technical field of aeronautics and astronautics, and specifically to an exhaust purification device for an aerospace plane.
BACKGROUND An airplane is a powered aircraft that is propelled forward by thrust from one or more engines, and the fixed wing of fuselage provides the lift force. An airplane is designed to fly inside the atmosphere of earth and is the most common fixed-wing aircraft. Airplanes fall into jet aircrafts and propeller aircrafts according to the type of engines. Since the airplanes are invented, airplanes have increasingly become an indispensable vehicle for transportation, which profoundly change and influence people's lives, and enable people to start the history of conquering the sky.
When existing aerospace airplanes are in flight, the exhaust is generated by the combustion of fuel in the engine, and the exhaust is the "contrail" of the airplane we see, which is also the exhaust of the airplane that needs to be purified. The exhaust is likely to stay due to the stable atmosphere at the cruising altitude. Moreover, there is sufficient ultraviolet radiation at the cruising altitude, which is an ideal place for photochemical reactions. The main components in the exhaust are carbon dioxide, nitrogen oxides, water vapor and particulate matter. Carbon dioxide directly causes the greenhouse effect, and nitrogen oxides are the main emissions of the engine. Nitrogen oxides can reduce ozone in the upper atmosphere under the photochemical reactions, thereby enhancing solar radiation and further accelerating global warming. Meanwhile, the long-wave radiation from the earth surface is absorbed by water and particulate matter at night, which significantly promotes the greenhouse effect. Furthermore, existing aircraft exhaust treatment devices are mostly intended to employ a better technology to filter the harmful components of the exhaust without considering that the aircraft exhaust is swirling when discharged. Since the swirling exhaust passes through the filter device, as a result, the central part of the filter device cannot be effectively utilized. In addition, the flow rate of the exhaust is fast, which is not convenient for complete and efficient purification. Therefore, it is imperative to provide a filter device capable of reducing the flow rate of the exhaust and allowing the exhaust to flow uniformly. Therefore, the present disclosure provides an exhaust purification device for an aerospace plane to solve this issue.
SUMMARY In view of the above-mentioned problems, in order to overcome the drawbacks of the prior art, the present disclosure provides an exhaust purification device for an aerospace plane, which effectively solves the problems of existing devices such as fast flow rate of the exhaust and low purification efficiency of the swirling exhaust. The exhaust purification device includes a housing, characterized in that, the left end and the right end of the housing are respectively provided with an air inlet and an air outlet. The air inlet is provided with a plurality of inclined spoilers which are uniformly and fixedly connected to the inner side wall of the housing. A straight deflector is fixedly connected to the right end of each of the plurality of inclined spoilers. The right side of the straight deflector is provided with a flow uniformizing structure that is fixedly connected in the housing. The right side of the flow uniformizing structure 1s successively provided with an activated carbon and a high-low voltage electric field, which are fixedly connected in the housing. The flow uniformizing structure includes a ventilation channel fixedly connected to the housing, and the inner diameter of the ventilation channel is smaller than the inner diameter of the housing. A plurality of diversion slopes are fixedly connected between the two ends of the ventilation channel and the inner side wall of the housing. The plurality of diversion slopes are provided with a plurality of flow uniformizing holes. Preferably, a diversion protrusion fixedly connected to the inner side wall of the housing is arranged between the straight deflector and the diversion slope. The left side and the right side of the diversion protrusion are both connected to the inner side wall of the housing through a slope. The included angle between the left slope of the diversion protrusion and the inner side wall of the housing is greater than the included angle between the right slope of the diversion protrusion and the inner side wall of the housing.
Preferably, the high-low voltage electric field includes a high voltage electric field adjacent to the air inlet and a low voltage electric field adjacent to the air outlet. The high voltage electric field and the low voltage electric field both include an anode plate and a cathode plate which are spaced apart. The distance between the anode plate and the cathode plate adjacent to the anode plate in the high voltage electric field is greater than the distance between the anode plate and the cathode plate adjacent to the anode plate in the low voltage electric field.
Preferably, the side wall of the housing is provided with an object falling opening located below the high-low voltage electric field. A switch board slidably connected to the side wall of the housing is arranged below the object falling opening. One end of the switch board 1s fixedly connected to one end of a spring and an electric telescopic rod, and the other end of the spring and the electric telescopic rod is fixedly connected to the housing. The lower end of the object falling opening is fixedly connected to a debris chamber fixedly connected to the housing.
Preferably, a control module fixedly connected to the housing is arranged on one side of the debris chamber, and the control module is electrically connected to the high- low voltage electric field and the electric telescopic rod.
Preferably, a switch door is arranged on the side wall of the housing corresponding to the activated carbon and the high-low voltage electric field.
A switch door is arranged on one side of the debris chamber.
The present disclosure makes improvements on the existing devices which have the issues such as fast flow rate of the exhaust and low purification efficiency of the swirling exhaust. The swirling airflow can be effectively converted into straight wind by the inclined spoiler and the straight deflector which cooperate with one another, so that the airflow can move towards the middle. The diversion protrusion, the diversion slope, and the flow uniformizing channel are additionally arranged to reduce the flow rate of the exhaust, so that the airflow can be uniformly blown to the filter device, thereby improving the filtration efficiency and the utilization rate of the filter device. The activated carbon cooperates with the electric field to effectively filter harmful gases and particulates in the exhaust. Meanwhile, free radicals are generated and react with nitrogen atoms in the exhaust to realize effective filtration. The high voltage electric field cooperates with the low voltage electric field to reduce the energy consumption while ensuring the filtration efficiency. The present disclosure has a simple structure and high practicability, and can efficiently filter harmful substances in the aircraft exhaust.

DETAILED DESCRIPTION OF THE EMBODIMENTS The foregoing and other technical contents, features, and advantages of the present disclosure will be clearly illustrated hereinafter with reference to the embodiments and FIGS. 1-6. The structures and contents mentioned in the following embodiments can refer to the drawings of the specification. The illustrative embodiments of the present disclosure will be described hereinafter with reference to the drawings.
In the first embodiment of the present disclosure, the exhaust purification device for aerospace includes the housing 1. The housing 1 penetrates from left to right. The exhaust passes through the housing 1 and is filtered by the subsequent structure. The left end and the right end of the housing 1 are respectively provided with the air inlet 2 5 and the air outlet 3. The air inlet 2 is provided with the plurality of inclined spoilers 4 which are uniformly and fixedly connected to the inner side wall of the housing 1. The right end of each of the plurality of inclined spoilers 4 is fixedly connected to the straight deflector 5. Referring to FIG. 3, the uniformly arranged inclined spoilers 4 can effectively separate and guide the swirling air around the swirling exhaust to the straight deflector 5. The exhaust is converted into straight wind under the action of the straight deflector 5, which facilitates the subsequent treatment and filtration. At this time, the airflow is still thin in the middle and dense in the periphery. The right side of the flow guide straight deflector 5 is provided with a flow uniformizing structure which is fixedly connected in the housing 1. The right side of the flow uniformizing structure is successively provided with the activated carbon 6 and the high-low voltage electric field 7 which are fixedly connected in the housing 1. The activated carbon 6 can initially adsorb carbon dioxide, nitrogen oxides, particles, water vapors, and others in the exhaust. Harmful substances in the exhaust can be fully treated by the high-low voltage electric field 7.
Referring to FIG. 4, the flow uniformizing structure includes the ventilation channel 8 fixedly connected to the housing 1, and the inner diameter of the ventilation channel 8 is smaller than the inner diameter of the housing 1. The plurality of diversion slopes 9 are fixedly connected between the two ends of the ventilation channel 8 and the inner side wall of the housing 1. The plurality of diversion slopes 9 are provided with the plurality of flow uniformizing holes 10. After the airflow passes through the ventilation channel 8 and the diversion slope 9, the dense airflow in the periphery flows through the flow uniformizing holes 10 of the diversion slope 9, and the remaining airflow that cannot pass is guided to the ventilation channel 8 in the middle under the action of the diversion slope 9 and flows through ventilation channel 8, so that the airflow passing through the ventilation channel 8 and the diversion slope 9 is converted into a uniform airflow, which can be fully utilized by the subsequent filter device, In the implementation of the present embodiment, the swirling exhaust flows through the inclined spoiler 4 and the straight deflector 5 and is converted into straight wind which is dense in the periphery and thin in the middle. Then, the exhaust flows through the diversion slope 9 and the ventilation channel 8 and is converted into uniform straight wind. Subsequently, carbon dioxide, nitrogen oxides, particles, and water vapors in the exhaust are initially adsorbed by the activated carbon 6, and finally purified by the high-low voltage electric field 7 and discharged.
In the second embodiment, based on the first embodiment, referring to FIG. 4, the diversion protrusion 11 fixedly connected to the inner side wall of the housing 1 is arranged between the straight deflector 5 and the diversion slope 9. The diversion protrusion 11 has a function of guiding the dense airflow in the periphery to the middle in advance. The left side and the right side of the diversion protrusion 11 are both connected to the inner side wall of the housing 1 through a slope. In this way, the diversion protrusion 11 is in smooth contact with the inner wall of the housing 1, which can contribute to guiding the airflow. The included angle between the left slope of the diversion protrusion 11 and the inner side wall of the housing 1 is greater than the included angle between the right slope of the diversion protrusion 11 and the inner side wall of the housing 1. The left slope with a relatively larger inclined angle allows the airflow in the periphery to move to the middle, which has a function of initially uniformizing the flow. The right inclined angle has a relatively small inclined angle and thus is relatively smooth, so that the airflow flows into the right diversion slope 9 and can pass through the diversion hole where the diversion slope 9 and the side wall of the housing 1 are connected, thereby improving the utilization efficiency of the diversion slope 9 and the diversion holes. Furthermore, according to the Venturi effect, the flow rate of the airflow increases in the most protruding portion of the diversion protrusion 11 due to a relatively small cross-sectional area, and the smooth slope on the right can effectively slow down the airflow.
In the third embodiment, based on the first embodiment, the high-low voltage electric field 7 includes the high voltage electric field 12 adjacent to the air inlet 2 and the low voltage electric field 13 adjacent to the air outlet 3. The high voltage electric field 12 and the low voltage electric field 13 both include an anode plate and a cathode plate which are spaced apart, and the anode plate and the cathode plate are staggered. Namely, the cathode plate is in front of and in back of each anode plate, and the anode plate is in front of and in back of each cathode plate. The distance between the anode plate and the cathode plate adjacent to the anode plate in the high voltage electric field 12 is greater than the distance between the anode plate and the cathode plate adjacent to the anode plate in the low voltage electric field 13. The high voltage electric field 12 is connected to an external power source through a transformer to form high voltage electricity, and the low voltage electric field 13 1s connected to the external power source. The voltage in the high voltage electric field 12 is high, to form an electric field with a greater attraction force, and thus the gap between the cathode plate and the anode plate of the high voltage electric field 12 is larger. The exhaust first enters the high voltage electric field 12, and is ionized in the electric field formed by the high voltage cathode plate through which high voltage electricity is passed and the high voltage anode plate grounded by the electric field frame. Most of the exhaust is degraded and carbonized after being charged. A small number of small particles move to the high voltage positive plate and negative plate of the electric field under the action of the electric field force of the electric field and the airflow, and are collected on the electrode plate and flows to the bottom of the high-low voltage electric field 7 due to gravity. After that, the remaining exhaust enters the low voltage electric field 13, and the small particles in the purified exhaust move to the low voltage positive plate and negative plate of the electric field under the influence of the electric field force and the airflow of the electric field, which are collected on the electrode plate and flow to the high-low voltage electric field 7 due to gravity, and the clean air 1s discharged ultimately. At the same time, the air in the electric field generates ozone under the action of the high voltage electric field 12, so as to remove the odor in the exhaust.
In the fourth embodiment, based on the third embodiment, the side wall of the housing 1 is provided with the object falling opening 14 located below the high-low voltage electric field 7. The object falling opening 14 allows the particles adsorbed by the high-low voltage electric field 7 to fall below the object falling opening 14 when the high-low voltage electric field 7 is not energized, so as to prevent the particles from being accumulated during use. The switch board 15 slidably connected to the side wall of the housing 1 is arranged below the object falling opening 14. The object falling opening 14 can be sealed by the switch board 15. One end of the switch board 15 is fixedly connected to one end of the spring 16 and the electric telescopic rod 17, and the other end of the spring 16 and the electric telescopic rod 17 is fixedly connected to the housing 1. The lower end of the object falling opening 14 is fixedly connected to the debris chamber 18 which is fixedly connected to the housing 1. The debris chamber 18 is configured to store particles and debris falling from the high-low voltage electric field
7. In the power-off state, the spring 16 is in a normal state, the electric telescopic rod 17 1s contracted, the switch board 15 does not block the object falling opening 14, and the object falling opening 14 is in an open state. In the power-on state, the electric telescopic rod 17 is extended, the spring 16 1s in a stretched state, and the switch board 15 seals the object falling opening 14 to prevent the exhaust from entering the debris chamber 18.
In the fifth embodiment, based on the fourth embodiment, the control module 19 fixedly connected to the housing 1 is arranged on one side of the debris chamber 18. The control module 19 is electrically connected to the high-low voltage electric field 7 and the electric telescopic rod 17. The control module 19 is connected to an external power source, and a booster amplifier circuit is integrated in the control module 19. The high voltage electric field 12 is electrically connected to the booster amplifier circuit, and the low voltage electric field 13 is electrically connected to the electric telescopic rod 17 and the control module 19.
In the sixth embodiment, based on the fourth embodiment or the fifth embodiment, characterized in that, the positions corresponding to the activated carbon 6 and the high- low voltage electric field 7 on the side wall of the housing 1 are both provided with the switch door 20. The switch door 20 is arranged on one side of the debris chamber 18.
The switch door 20 is arranged to facilitate the disassembly, cleaning, and maintenance of various components.
When in use, the control module 19 is energized, the control module 19 supplies power to the high-low voltage electric field 7 and the electric telescopic rod 17, and the electric telescopic rod 17 is extended to close the object falling opening 14.
The swirling airflow passes through the inclined spoiler 4 and the straight deflector 5, is converted into straight wind which is dense in the periphery and thin in the middle, 1s uniformized and diverted through the diversion protrusion 11 initially, and then flows through the diversion slope 9 and the ventilation channel 8 to become uniform straight wind. Subsequently, carbon dioxide, nitrogen oxides, particles, and water vapors in the exhaust are initially adsorbed by the activated carbon 6, and finally purified by the high- low voltage electric field 7 and discharged.
After use, the power needs to be cut off. At this time, under the action of the spring 16, the switch board 15 is opened, and the object falling opening 14 is exposed. The particles and debris adsorbed by the high-low voltage electric field 7 fall into the debris chamber 18 through the object falling opening 14.
In view of the problems of existing devices such as fast flow rate of the exhaust and low purification efficiency of swirling exhaust. The present disclosure makes improvements in existing devices, and the inclined spoiler and the straight deflector cooperate with one another, which can effectively convert the swirling airflow into straight wind, so that the airflow can move to the middle. The diversion protrusion, the diversion slope and the flow uniformizing channel are additionally arranged to reduce the flow rate of the exhaust, so that the airflow can be uniformly blown to the filter device, thereby improving the efficiency and utilization rate of the filter device. The activated carbon cooperates with the electric field to effectively filter harmful gases and particulates in the exhaust. Meanwhile, free radicals are generated and react with nitrogen atoms in the exhaust to realize effective filtration. The high voltage electric field cooperates with the low voltage electric field to reduce the energy consumption while ensuring the filtration efficiency. The present disclosure has a simple structure and strong practicability, and can efficiently filter harmful substances in the exhaust of the aircraft.
