Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of artificial weather influencing operations, and more particularly to an impact-type artificial fog reduction catalysis method and a composite bomb thereof. Background Art
[0002] Fog, as a weather phenomenon with widespread impact, causes serious problems for transportation, health, and production activities. From the perspective of artificial weather modification, fog can be divided into two categories: cold fog and warm fog. Cold fog is composed of supercooled water droplets below 0°C, while warm fog is composed of liquid water droplets above 0°C. Current artificial fog reduction technology has obvious limitations. For cold fog reduction methods, the mainstream method is to spread catalysts such as dry ice, silver iodide, or liquid nitrogen to cause water vapor to condense and settle on ice crystals. Although this technology is relatively mature, it relies on high-cost catalytic substances and is not applicable to warm fog scenarios. As for warm fog reduction methods, existing technologies include moisture absorption, heating, disturbance mixing, and acoustic wave reduction. The moisture absorption method generates condensation nuclei by spreading moisture absorbents such as calcium chloride, urea, or salt powder, causing the droplets to collide and grow before settling. However, the natural diffusion efficiency of the catalyst is low, making it difficult to remove tiny droplets with a diameter of less than 10 microns. The heating method relies on high-temperature gas to evaporate the droplets, which consumes extremely high energy (over 1,000 kilowatt-hours per operation) and is difficult to apply in practice. The disturbance mixing method uses helicopters or propellers to stir the air to promote dry-wet mixing, but its effective range is less than 200 square meters and is costly. The acoustic wave reduction method uses low-frequency sound waves to induce droplet collision and condensation. Due to the rapid attenuation of sound waves, the effective range is only 50-100 meters and the duration is less than 10 minutes. In summary, existing manual abatement methods and technologies have three core flaws: first, cold fog and warm fog abatement methods require independent systems and lack a universal solution; second, warm fog abatement methods are inefficient, with a tiny droplet removal rate of less than 40%; third, the cost of efficient means far exceeds the practical threshold. Summary of the Invention

[0015] The present invention proposes an impact catalytic method for artificially reducing fog, comprising: Use the launcher to push the artificial fog reduction composite bomb (similar to a fireworks display) to the predetermined height in the fog area (the launch location should be selected as follows: within 4 kilometers upwind of the operation impact area, on the windward slope or on a path with frequent fog drift, with a wide field of vision; more than 500 meters away from residential areas or national highways, with no people gathered nearby; the area has issued a weather modification operation notice, and the altitude is designed to be controlled within 300 meters to ensure that it does not affect the use of the airspace and meets airspace safety requirements; before launching the artificial fog reduction composite bomb, check whether the outer packaging is damaged, the packaging is poor, or the bomb body is cracked). Triggering the secondary explosion of the artificial fog reduction composite bomb, using the dynamic effect of the explosion shock wave to cause the fog droplets to violently collide and condense; Synchronously release the hygroscopic powder or artificial ice nucleation catalyst filled in the artificial fog reduction composite bomb, wherein: The chemical action of the catalyst causes the droplets to condense and evaporate; Hygroscopic powder accelerates the condensation and collision and precipitation of water vapor by absorbing moisture, or artificial ice nuclei accelerate the formation of ice crystal particles and collision and precipitation of fog droplets by providing ice nuclei for cold fog; The dynamic effect of explosion shock wave, the chemical action of catalyst and the hygroscopic powder or artificial ice nucleus absorbing moisture and colliding and growing or the artificial ice nucleus growing and colliding and settling work together to achieve fog reduction.
[0016] Example 1 (using streamlined body): Structure description: refer to Figure 1 As shown, the artificial fog reduction composite bomb includes: a streamlined shell (the streamlined shell body can reduce air resistance, improve launch accuracy and flight stability, and the shell is made of paper) and an ignition base fixed to the bottom; The interior of the ignition base is filled with propellant; The streamlined shell is provided with a star layer and a core layer from the outside to the inside; The core layer is filled with fog-reducing hygroscopic powder (bentonite, NaCl, CaCl2, etc.) or artificial ice nucleation catalyst; The built-in delay fuse runs through the streamlined shell and the ignition base, extends to the core layer and the star layer and is buried therein, and is used to trigger the release of fog-reducing hygroscopic powder or artificial ice nucleus catalyst; The external fuse is installed on the ignition base, one end of which passes through the surface of the ignition base and the other end is connected to the propellant; A coil is provided on the top of the streamlined housing for fixing the external lead wire; The mist reduction catalyst is selected from one of hygroscopic powders or artificial ice nuclei; Workflow: Ignite the external fuse → detonate the propellant to propel the projectile to a height of less than 300 meters → the built-in delayed fuse triggers the secondary explosion of the core layer → the shock wave causes the fog droplets to collide and condense, the fog reduction catalyst promotes condensation and evaporation, the hygroscopic powder or artificial ice nucleus grows and collides to promote sedimentation → synergistically reduce fog.
[0017] Example 2 (using a straight-cylinder body): Structure description: refer to Figure 2 As shown, the elastic body structure of embodiment 1 is adopted and the coil structure is eliminated, and a straight cylindrical shell and a paper cover movable along the inner wall thereof are additionally provided; The artificial fog reduction composite bomb is placed at the bottom of the straight cylindrical shell and below the paper cover to form a sealed cavity; Working process: The straight cylindrical shell is directly used as the launching tube. After the projectile is loaded, it is ignited through the external fuse → the propellant pushes the paper cover upward to open the channel → the propellant is detonated to propel the projectile to a height of less than 300 meters. After the projectile is launched, a secondary explosion is performed to reduce fog → the shock wave causes the fog droplets to collide and condense, the fog reduction catalyst promotes condensation and evaporation, the hygroscopic powder or artificial ice nuclei grow and collide to promote sedimentation → synergistically reduce fog.
[0018] Example 3 (using a launch device): Structure Description: Reference Figure 3 As shown, the base: carries the angle adjustment module, height adjustment module and launch tube; Launch tube: supports the straight shell (structure of Example 2); Angle adjustment module: stepper motor controls the launch tube to adjust the angle; Height adjustment: The bolt-on straight barrel housing is fixed inside the launch tube, and its height can be adjusted; Control module: key-type data input or percussion-type or display interface control. The operator can set the firing parameters through key input, including the number of shots, firing interval time, firing angle parameters, etc. Ignition device: electronic ignition device directly connected to external lead; Workflow: The emission parameters are automatically calculated according to the position of the fog area, the control module automatically adjusts the emission angle, and the electronic ignition triggers the external fuse to ignite. The subsequent workflow is the same as that of Example 2.
[0019] The present invention addresses the three major defects of existing fog reduction technologies, namely the separation of cold fog and warm fog treatment solutions, low efficiency of tiny droplet removal, and high cost that makes practical use difficult. The present invention proposes a triple synergistic fog reduction mechanism that integrates the dynamic effect of explosion shock waves, the condensation effect of chemical catalysts, and hygroscopic powders that accelerate water vapor condensation and collision and sedimentation through moisture growth, or artificial ice nuclei that provide ice nuclei for cold fog to accelerate the formation of ice crystal particles and collision and landing of droplets. The core of the mechanism is to synchronously trigger the coupling of physical, chemical and dynamic processes through the secondary explosion of the artificial fog reduction composite bomb: the explosion shock wave forces tiny droplets to violently collide and merge into large droplets, breaking through the bottleneck of low efficiency of traditional methods in removing tiny droplets (<10μm); the hygroscopic powder, with its high specific surface area of the layered structure, absorbs free water vapor and increases weight and settles; the hygroscopic powder or artificial ice nuclei and other catalysts adaptively exert hygroscopic condensation (warm fog) or ice nucleation effect (cold fog) according to the fog type, realizing universal treatment of cold and warm fog; the three form a "collision-condensation-adsorption" closed loop, effectively preventing secondary fog formation; To achieve this technology, the present inventors have designed a composite bomb for artificial fog reduction: the bomb body is filled with a catalyst in the center and surrounded by a ring of hygroscopic powder (bentonite, NaCl, CaCl2, etc.) or artificial ice nuclei. After being delivered to the fog area via a simple launch device, a delayed fuse precisely triggers a secondary explosion. The explosion instantly completes three key actions: the diffusion of the shock wave causes fog droplets to collide, the catalyst is evenly dispersed, and the catalyst is spread over a large area. A specially designed straight-cylinder storage shell and moisture-proof paper cover protect the bomb body and facilitate transportation. During use, the paper cover automatically ruptures to release the bomb body, making it easy and safe to operate. Compared with traditional methods, this technology has significant advantages: first, it is highly versatile, and the same device can handle various fog conditions from minus 20 degrees Celsius to room temperature; second, the cost is greatly reduced, hygroscopic powders or artificial ice cores are common materials, and the cost of a single operation is only one-tenth of that of aircraft seeding; third, it is quick to take effect, and the on-board equipment can be deployed in five minutes. It is particularly suitable for airport runway defogging (to avoid large-scale flight delays), emergency response in foggy sections of highways (to prevent chain reactions), ports, and other scenarios with high timeliness requirements. At the same time, all materials are environmentally friendly, and the catalyst components used meet safety standards. This solution organically combines physical collision, chemical action and natural adsorption principles, and achieves efficient and low-cost fog damage prevention and control through a structural design similar to that of fireworks, and has practical value for large-scale promotion.
