Abstract
The invention discloses a method for eliminating heavy fog on water surfaces by means of local quick rainmaking, and belongs to the technical field of safety guarantee for ships. The method for eliminating the heavy fog on the water surfaces by means of local quick rainmaking includes respectively arranging three devices capable of releasing artificial raindrops to the air on a bow, the left side and the right side of a ship, and releasing large quantities of raindrops; continuously acquiring fog-drops in raindrop falling procedures to form large water drops and further improve the acquisition efficiency; quickly eliminating the fog-drops in specific regions to achieve the purpose of eliminating the fog and enable operation or activities on water to be smoothly executed. The method with the technology has the advantages that the method is convenient to implement, attached devices are simple in structure and can be conveniently arranged on the bow and the two sides of the ship, and accordingly the method has an excellent application prospect.
Description
Technical field
The present invention relates to the local rapid artificial rain removing method of making of a kind of water surface dense fog, it belongs to safety of ship safeguards technique field.
Background technology
Dense fog can reduce visibility, has a strong impact on aeroamphibious traffic.For reducing the impact of dense fog, conventionally adopt manual method to make fog dissipation, be called arrtificial fog dissipation.Arrtificial fog dissipation technology is normally distinguished changes in temperature mist with the physical arrangement of mist, and takes different defogging methods for the difference formation mechanism of warm fog and cold mist.
One, the cold mist method that manually disappears.Be to be mainly Main Basis according to the theory of ice cloud and water cloud mixing generation precipitation, by broadcasting sowing Artificial Ice Crystal to cloud and mist district, promote steam and ice crystal to condense and increase rear landing to reach elimination fog effect.This method has been verified and has obtained practical application in the effect of ground fog dispersal.
Two, the warm fog method that manually disappears.Be mainly to make droplet become large sedimentation or evaporation disappears, thereby make fog dissipation.Compare with cold mist, it is more complicated that warm fog forms mechanism.Based on this, existing elimination warm fog method is divided into three kinds according to its mechanism conventionally: the drop method of 1) condensing.In mist, sow moisture absorption particle as catalyzer, produce a large amount of nuclei of condensation, steam condenses and grows up to large water droplet on the nuclei of condensation, causes droplet evaporation and condenses on large water droplet, and mist is disappeared; 2) heating vaporization.In fog-zone among a small circle, add hot air, to evaporate droplet, make its disappearance; 3) disturbance mixing method.By aircraft, in top, fog-zone agitation air, order about dry air and mix with air in mist, accelerate droplet and dissipate.
As fully visible, current used all kinds of arrtificial fog dissipation methods can play a role in aviation and speedway key area, alleviate the harm that dense fog causes to people's productive life.But these methods are all subject to geographical conditions restriction obviously, cannot be applied to the elimination of water surface dense fog.And each defogging method can only solve local cold mist or local warm fog phenomenon, for the changeable water environment of weather, be difficult to promotion and implementation.
Summary of the invention
For solving water surface dense fog, eliminate a difficult problem, the invention provides the local rapid artificial rain removing method of making of a kind of water surface dense fog, the method should make droplet dissipate as early as possible, thereby guarantees safety of ship, makes operation at sea be able to smooth execution.
The technical solution adopted for the present invention to solve the technical problems is: the local rapid artificial rain removing method of making of a kind of water surface dense fog, and the step that it adopts is as follows:
A, at boats and ships bow and left and right two sides of a ship, be respectively provided with one to the device that discharges artificial raindrop in the air;
B, described in make rain bottom of device and be connected with water absorber;
C, described water absorber supply water to making rain device, spray the artificial raindrop that can eliminate fast specific region droplet by shower nozzle.
The described front end of making rain device is shower nozzle, and >0 degree is answered at the elevation angle of shower nozzle.
Described water absorber is constant pressure frequency conversion supply equipment peculiar to vessel.
The invention has the beneficial effects as follows: the local rapid artificial rain removing method of making of this water surface dense fog, the method is respectively provided with one at the bow of boats and ships and left and right two sides of a ship can, to the device that discharges artificial raindrop in the air, discharge a large amount of raindrop.In raindrop landing process, constantly intercept and capture droplet, form thus larger water droplet, further improve capture efficiency.Thus, the droplet of particular locality is eliminated fast, reaches the object of fog dispersal, makes operation at sea or action be able to smooth execution.This utilization is convenient, and optional equipment is simple in structure, is convenient to be arranged on boats and ships bow and two sides of a ship, has good application prospect.
The specific embodiment
The local rapid artificial rain removing method of making of water surface dense fog is to implement like this:
A, at boats and ships bow and left and right two sides of a ship, being respectively provided with one can be to the device that discharges artificial raindrop in the air;
B, described in make rain bottom of device and be connected with water absorber;
C, described water absorber supply water to making rain device, spray the artificial raindrop that can eliminate fast specific region droplet by shower nozzle.
The technical basis of this rainmaking removing method is: rainmaking fog dispersal technology mainly refers to the intensity of rainmaking, the scope that realizes of rainmaking, shower nozzle shape, and these features will be the critical technical parameters such as working method, working depth and overall dimensions of design rainmaking fog dispersal equipment.
1, can rainmaking intensity rainmaking technology effectively intercept and capture droplet fast, and the intensity of raindrop is key factors.It has been generally acknowledged that intensity is larger, fog dispersal efficiency can significantly increase.
2, rainmaking is realized scope for ship's navigation state, and rainmaking fog dispersal scope is mainly determined by navigation visibility.Visibility is lower, need reach to make rain fog dispersal scope larger.
3, shower nozzle shape drop is less, and its fog dispersal efficiency of shower nozzle that water consumption is less is higher.
The guiding theory of technique scheme is: the intercepting and capturing effect of raindrop to droplet.It is generally acknowledged that raindrop have three kinds of intercepting and capturing effects to droplet: 1. coverage mode.Raindrop are affected by gravity and are vertical landing state, directly contact with the droplet in below, form larger volume drop and are subject to effect of inertia to continue sedimentation, and in infall process, drop is is constantly intercepted and captured droplet, finally reaches elimination fog effect; 2. touch on mode only lightly.It is close gradually that raindrop and near droplet are affected by intermolecular force/hydrogen bond force, from EDGE CONTACT, is developed to each other and merges.Until the drop of assembling arrive greatly the gravity himself producing surpass air climbing power and surface tension of liquid with joint efforts time, drop generation sedimentation, reaches elimination fog effect; 3. entrainment mode.During raindrop landing, drive near the Air Flow of raindrop, air velocity change causes greatly atmospheric pressure to diminish.Air Flow is at a distance slower, and air pressure is constant, and droplet is stressed to differ to act on and is pushed to raindrop.Both merge, until the drop of assembling arrive greatly the gravity himself producing surpass air climbing power and surface tension of liquid with joint efforts time, raindrop generation sedimentation, reaches elimination fog effect.
