Description

Technical Field

[0001] The utility model relates to the field of aviation support technology, in particular to an airport demisting device system which utilizes a high-pressure air storage and air release pipe network and a combined device of a high-energy directional microwave transmitter to eliminate water mist in the air of an airport or other outdoor work sites with specific requirements on visibility. Background Art

[0002] Fog has always been the main weather phenomenon that interferes with the normal operation of airports. When visibility drops to the level of heavy fog, it will endanger flight safety and seriously hinder the take-off and landing of flights. The affected area of ​​fog is usually wide, thick, and large in scale. Reliable defogging equipment and technology that can be scaled up have not been developed and put into practical use. At present, heavy fog is still one of the major obstacles to the normal operation of airports.

[0003] There are two most basic conditions for the formation of fog in the air, namely the temperature and humidity of the air: humidity is higher than the saturated water content, and temperature is lower than the dew point temperature. The most direct way to resolve fog is to adopt different targeted engineering measures to change the characteristic values ​​of the main causes of fog.

[0004] By utilizing the large amount of dry air emitted when a compressed air energy storage power station generates electricity, and arranging gas pipelines and regulating and controlling devices such as gate valves on the ground or near the ground in the target area, the air emission rate and quantity can be controlled as needed to dilute the water content in the air and reduce the air humidity, thereby reducing the fog concentration in target airspace close to the ground such as runways.

[0005] The substances that reduce visibility in fog are a large number of fine particles of water suspended in the air. Since the dielectric constants of air and water are significantly different, when microwaves irradiate foggy airspace, they can selectively and directly heat the small water droplets in the air, promoting their rapid heating and vaporization. Microwaves have the advantages of high heating efficiency, large effective distance, and accurate directional emission.

[0006] Compressed air energy storage power stations have made great progress in my country in recent years. Grid-connected power stations have been put into operation, with a single unit scale of 350 megawatts. The system efficiency has reached 70%. Large-capacity, high-efficiency, and ultra-long-duration air energy storage power generation equipment has entered the practical and commercial stage.

[0007] Microwave generator system: China has developed relatively mature high-power microwave generation and transmission equipment in the frequency band with the highest water heating efficiency. For example, Nanjing Sanle Microwave Technology Development Co., Ltd.'s CK-2111, 2450MHz magnetron, the output power of a single generator has reached 30kw. Summary of the invention

[0008] The utility model aims to solve the problem that foggy weather seriously affects the normal operation of airports. It provides an airport demisting device system which utilizes a high-pressure air storage and air release pipe network and a combined device with a high-energy directional microwave transmitter to eliminate water mist in the air of airports or other outdoor work sites with specific requirements on visibility.

[0009] The utility model discloses an airport defogger system, which is arranged in an airport and is characterized in that the defogger system comprises an air delivery pipeline, an air release control network, a compressed air energy storage power station, a compressed air storage facility and a microwave generating and transmitting array. The compressed air energy storage power station and the compressed air storage facility are arranged in a safe position in the airport, and the compressed air storage facility is connected to the exhaust end of the generator of the compressed air energy storage power station; the release control network is arranged along the runway of the airport, and the compressed air storage facility is connected to the release control network through an air delivery pipeline; and the microwave generating and transmitting array is arranged at both ends of the runway.

[0010] The microwave generating and transmitting array is composed of a plurality of microwave generating and transmitting units, each of which includes a high-power microwave generator and a transmitting antenna. The microwave generator operates in a frequency band with high water heating efficiency. The microwave generating and transmitting array is arranged near the end of the runway, equipped with sufficient power and can be flexibly positioned as needed to illuminate relatively high and distant target airspaces such as the lift belt, directly heat tiny water bodies in the air, promote their vaporization, and thus improve visibility.

[0011] The air release control pipe network is also provided with an electric regulating valve, through which the amount of air released is adjusted. The electric regulating valve is a ZXPE micro-flow regulating valve produced by Jiangsu Juliang Automatic Valve Co., Ltd.

[0012] This device cooperates with dry air storage and release and microwave irradiation facilities to form an airport defogger system that can be reasonably matched at high and low, far and near, thereby improving visibility in key airspace such as airport runways, approach and landing, and take-off and climb areas. It can effectively reduce the impact of fog on key airspace of airport operations and improve the airport's ability to ensure the safety of aircraft takeoff and landing.

[0013] Compressed air energy storage power stations use electricity during off-peak hours of the power grid to compress and store air. When fog covers the airport and affects its operation, the compressed air energy storage power station is dispatched to generate electricity. Through the air release control network, a large amount of dry air discharged by the compressed air energy storage power station is released along the airport runway, near landing and take-off climbing areas, and important traffic lines, diluting the humid air, reducing the humidity of the target airspace, and eliminating fog. For areas far from the ground and difficult to be affected by ground exhaust, microwave generation and emission arrays are used for directional irradiation. The significant difference in the dielectric constants of air and water is used to selectively and accurately heat the micro-particle water in the target airspace, promote its vaporization, and quickly reduce the fog concentration in relatively high and distant target airspaces such as aircraft landing approach areas and climb areas, improve visibility, and meet safe flight standards.

[0014] The airport defogger system of the utility model utilizes the air discharged during power generation of the compressed air energy storage power station for defogger. First, the air volume is large and can reach the necessary scale; second, the investment of the defogger system is shared through the operating income of the compressed air energy storage power station, reducing the operating cost; third, the compressed air energy storage power station generates electricity and exhausts synchronously, which can directly power the high-power microwave generator, and utilize the electricity stored during the off-peak period of the power grid to reduce the operating cost of the airport defogger system. The whole set of equipment is economical and environmentally friendly, can enhance the power supply guarantee of the airport, can adjust the load of the power grid, and has many application values.

[0018] Embodiment 1: An airport defogger system is arranged in the airport. The defogger system includes an air delivery pipeline, an air release control network, a compressed air energy storage power station, a compressed air storage facility, and a microwave generation and emission array. The compressed air energy storage power station and the compressed air storage facility are arranged in a safe position in the airport. The compressed air storage facility is connected to the exhaust end of the generator of the compressed air energy storage power station. The release control network is arranged along the runway of the airport. The compressed air storage facility and the release control network are connected through an air delivery pipeline. The microwave generation and emission array is arranged at both ends of the runway. The microwave generation and emission array is composed of a plurality of microwave generation and emission units. Each microwave generation and emission unit includes a microwave generator with a power of 30kw and a transmitting antenna. The microwave generator operates in a frequency band with high water heating efficiency. The microwave generation and emission array is arranged near the end of the runway, equipped with sufficient power and can be flexibly positioned as needed to irradiate relatively high and distant target airspaces such as lift strips, directly heat tiny water bodies in the air, promote their vaporization, and thus improve visibility.

[0019] An electric regulating valve is also provided on the air release control pipe network. The amount of air released is adjusted by the electric regulating valve. Dry air can be released according to the specific situation of the fog to quickly defog. The electric regulating valve uses the ZXPE micro-flow regulating valve of Jiangsu Juliang Automatic Valve Co., Ltd.

[0020] This device cooperates with dry air storage and release and microwave irradiation facilities to form an airport defogger system that can be reasonably matched at high and low, far and near, thereby improving visibility in key airspace such as airport runways, approach and landing, and take-off and climb areas. It can effectively reduce the impact of fog on key airspace of airport operations and improve the airport's ability to ensure the safety of aircraft takeoff and landing.

[0021] Compressed air energy storage power stations use electricity during off-peak hours of the power grid to compress and store air. When fog covers the airport and affects its operation, the compressed air energy storage power station is dispatched to generate electricity. Through the air release control network, a large amount of dry air discharged by the compressed air energy storage power station is released along the airport runway, near landing and take-off climbing areas, and important traffic lines, diluting the humid air, reducing the humidity of the target airspace, and eliminating fog. For areas far from the ground and difficult to be affected by ground exhaust, microwave generation and emission arrays are used for directional irradiation. The significant difference in the dielectric constants of air and water is used to selectively and accurately heat the micro-particle water in the target airspace, promote its vaporization, and quickly reduce the fog concentration in relatively high and distant target airspaces such as aircraft landing approach areas and climb areas, improve visibility, and meet safe flight standards.

[0022] Normally, the compressed air energy storage power station operates normally and balances the load on the power grid. When there is a heavy fog warning, the operating status of the compressed air energy storage power station is dispatched to undertake the airport defog task, power the high-power microwave generating and transmitting array in the defog system, and provide the air transportation and release pipeline 4 with dry air discharged when the generator set is working.
