Description
Technical Field
The invention relates to the technical field of artificial rainfall equipment, in particular to an electrothermal sublimation type Leng Yun catalyst sowing device.
Background
Rocket and airborne scattering devices are widely used in weather modification operation to realize cloud broadcasting catalysis operation, and catalysts suitable for the scattering mode are mainly flame agents or flame bars containing silver iodide. In the spreading process, the flame agent and the flame strips can be burnt on the plane or carried by a rocket to the air for burning. Different operation modes have different requirements on the technical form of the flame agent, the material formula and the design of the seeding device. Therefore, it is necessary to design different dispersing devices to meet the requirements of different shadow jobs.
At present, airplanes, launching frames, ground combustion sowing furnaces, airborne sowing devices, rocket projectiles, high shells, tobacco rods and flame projectiles are main equipment for artificially influencing weather operation. The aircraft has strong maneuverability, can directly broadcast the catalyst into the preset position in the cloud, broadcast evenly, the coverage area is wide, is the best platform of broadcasting in the cloud. The method of carrying and scattering the silver iodide catalyst as the active ingredient by the airplane is an effective means for implementing large-scale artificial precipitation. However, the aircraft has high working height, is in a low-oxygen, low-temperature, low-pressure and high-humidity environment, and has high requirements on the sowing device. Currently, the on-board flame strips used for the catalyst sowing of the aircraft mainly rely on the burning mode of fire attacks to perform the catalyst sowing, and the on-board flame strips face a great challenge in a series of problems such as tightness of flame strips, ignition mode, sufficiency of burning, elimination of open burning flame and the like. Especially in the flame combustion process, in order to ensure that silver iodide is fully sublimated and dispersed in a high-altitude cloud layer, a large amount of combustion improver and explosive are added into flame auxiliary materials, so that a certain hidden danger exists in the production, transportation and storage processes of the airborne flame, particularly when the flame is combusted and scattered on an aircraft, the reaction is severe, and the flame has a large open flame, so that the safety of the aircraft is threatened greatly, and the environmental pollution is influenced to a certain extent. Meanwhile, a large amount of auxiliary materials lead to a single onboard flare to have larger flare quality and limited onboard quantity.
