Abstract
The invention discloses a method for eliminating fog by means of sound waves. The method for eliminating the fog by means of the sound waves is characterized in that a main device used when the fog is eliminated by means of the sound waves is a sound wave fog eliminating device, and the sound wave fog eliminating device is mainly composed of a signal generator, a power amplifier, a loudspeaker and a power supply. The signal generator can generate an electric signal at a certain frequency, the electric signal can be amplified by the power amplifier, the loudspeaker can convert the electric signal into a sound signal, and the power supply is used for supplying power. When the fog appears, the power supply is powered on, the electric signal at the frequency between 15 GHz and 0.5 GHz is generated by the signal generator and is amplified by the power amplifier, the electric signal output by the power amplifier is converted into a sound signal by the loudspeaker, vapor in the fog vibrates along with the sound waves, small water drops are converged into big water drops, then rainwater is formed and falls on the ground, and the fog is eliminated rapidly. By the adoption of the method for eliminating the fog by means of the sound waves, serious harm and threats caused by the fog to people on the aspects of traffic activities, agricultural production, electric power supply, health and safety are well avoided, and normal agricultural production and normal life, traveling and health of people are guaranteed.
Description
Technical field
The invention belongs to meteorological technical field, particularly a kind of method of utilizing sound wave to eliminate mist, is applicable to the elimination of the mist in relevant place.
Background technology
Mist is a kind of common weather phenomenon, is the visible aggregate that is suspended in a large amount of fine water droplets (or ice crystal) in the atmosphere of ground proximity, be that the moisture in atmosphere is evaporated by earth surface, rise and condensation after generate.Mist is one of weather that mankind's traffic activity is had the greatest impact, and the safety such as agricultural production, supply of electric power is caused to harm in various degree, also the mankind's health is formed greatly and is threatened simultaneously.Speedway, Civil Aviation Airport are implemented road closure and stop the phenomenon of class of common occurrence because of the appearance of dense fog, and what have even also causes pernicious traffic accident.Data according to ASSOCIATE STATISTICS show, due to the traffic accident that foggy weather causes, will exceed 2.5 times with respect to other diastrous weathers, injury to personnel, dead ratio have accounted for that traffic accident is injured especially, dead sum 29.5% and 16%.And in urban traffic, increase by 20% left and right because foggy weather can make the magnitude of traffic flow of city working peak period, 30% left and right of also rising of traffic accident simultaneously.Dense fog is also to cause supply of electric power and one of the main reasons that security incident occurs.In circuit transmission of electricity process, if the insulator arrangement surfaces such as transfusion bottle, porcelain vase can reduce performance and the safety factor of insulation greatly with a large amount of droplets, make ultra-high-tension power transmission line occur tripping operation or short circuit, i.e. pollution flashover disaster.According to data, between 10 to 21 February of nineteen ninety, there is rare dense fog phenomenon in North China, cause the insulating properties of power transmission and transforming equipment significantly to reduce, cause 51 transmission lines of electricity in Beijing-Tianjin-Tangshan Grid trip accident to occur altogether 147 times more than, make urban electricity supply in emergency, only just have an appointment 200 integrated mills and industrial unit of Beijing stops producing because rationing the power supply 2 days, and its economic loss causing cannot be estimated.There is harm in greasy weather equally for agricultural production, its main manifestations: crops photosynthesis weakens, and light application time reduces.Under normal conditions, greasy weather can cause photo-thermal resource provisioning deficiency, its light application time generally can shorten 3～4 hours, serious reaches 6～8 hours, photosynthetic usefulness is significantly declined, greatly reduced photosynthate, the needed nutrient of crop growth and energy can not get fully meeting, thereby affect its normal growth and growth.In addition, foggy weather has also caused serious threat for the health of human body.The small globule floats in low latitude while forming mist, can and be dissolved among droplet some hazardous substances absorption of ground surface, as pathogenic microorganism, dust, acid, salt, alkali etc., these hazardous substancess are gathered and are detained and can not be diluted or spread, will make the degree of polluting increase the weight of, and increase along with continuing of foggy weather.So far, also there is no the device of artificial quick elimination mist, can only wait for passively leaving of mist, therefore the device of mist is eliminated fast in research, and separating serious harm and the threat that demist causes mankind's traffic activity, agricultural production, supply of electric power and healthy and safe etc. is very important problem.
Summary of the invention
The object of the invention, has been to provide a kind of sound wave that utilizes and has eliminated the method for mist, solves the problem of the mist in relevant place, separates serious harm and threat that demist causes mankind's traffic activity, agricultural production, supply of electric power and healthy and safe etc.
The technical scheme adopting is
Utilize sound wave to eliminate a method for mist, the equipment that sound wave demist adopts is sound wave demister, and this device is mainly made up of signal generator, power amplifier, loudspeaker and power supply.
Signal generator can produce the signal of telecommunication of certain frequency, and power amplifier can amplify the signal of telecommunication, and loudspeaker can convert the electrical signal to acoustic signal, and power supply is responsible for power supply.
In the time that mist occurs, power supply energising, signal generator produces the signal of telecommunication that frequency is 15～0.5GHz, the signal of telecommunication is amplified by power amplifier, loudspeaker converts the signal of telecommunication of power amplifier output to acoustic signal, and the steam in mist is along with sound wave shakes, and droplet pools large water drop, and then form rainwater drop to ground, mist is eliminated fast.
Advantage and effect: the present invention has solved serious harm and the threat that mist causes mankind traffic activity, agricultural production, supply of electric power and the each side such as healthy and safe preferably.By the enforcement of technical solution of the present invention, can quick solution the problem of mist in relevant place, guaranteed that normal industrial and agricultural production and people live normally, trip and healthy etc., reduce the tremendous economic loss that mist causes simultaneously.
Accompanying drawing explanation
Fig. 1 is that the outer sound wave of the present invention disappears in defogging method and uses sound wave demister schematic diagram.
The specific embodiment
Utilize sound wave to eliminate a method for mist, it is characterized in that the capital equipment using in sound wave demist is sound wave demister, this device is mainly made up of signal generator 1, power amplifier 2, loudspeaker 3, power supply 4.
Signal generator 1 can produce the signal of telecommunication of certain frequency, and power amplifier 2 can amplify the signal of telecommunication, and loudspeaker 3 can convert the electrical signal to acoustic signal, and power supply 4 is responsible for power supply.
In the time that mist occurs, power supply 4 is switched on, signal generator 1 produces the signal of telecommunication that frequency is 15～0.5GHz, the signal of telecommunication is amplified by power amplifier 2, the signal of telecommunication that loudspeaker 3 is exported power amplifier 2 converts acoustic signal to, and the steam in mist is along with sound wave shakes, and droplet pools large water drop, and then form rainwater drop to ground, mist is eliminated fast.
