The specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of airport demister, comprise ion generator 7, ion generator support 8, Horizontal fan 9, described ion generator 7 is arranged on ion generator support 8, Horizontal fan 9 be arranged on ion generator 7 below.
Described ion generator 7 comprises that input power 1, rectifier filter 2, DC converter 3, high-tension transformer 4, voltage-doubler rectifier 5, the metal electric of connection have a fainting spell during acupuncture treatment 6 successively.Described ion generator 7 is connected with high voltage control box, after software Centralized integrated control box, then is connected with computer remote control appliance.Described ion generator 7 is used stainless steel frame.Described Horizontal fan 9 comprises inlet scoop 12, air outlet and fan 11, and water-absorbing resin 10 is equipped with in 12 inside, inlet scoop, and fan 11 is arranged on the centre of Horizontal fan 9, and only inlet scoop 12 and air outlet are in communication with the outside, and all the other structures are closed.Described Horizontal fan 9 has four inlet scoops 12.Four inlet scoops 12 are evenly distributed on same circumference.
As shown in Figure 1,220V input power 1 is after rectifier filter 2, output dc voltage, through DC converter 3, produce the higher-order of oscillation again, then through high-tension transformer 4, boost and circuit voltage-doubler rectifier 5, obtain the negative high voltage of volts up to ten thousand, be added in metal electric and have a fainting spell during acupuncture treatment on 6, make it that corona discharge effect occur, discharge anion.
Corona discharge is a kind of form of gas self-maintained discharge, and it does not need additional ionization source to cause and sustain discharge.In order to keep stable corona discharge, must form an inhomogeneous field.Along with being applied to the increase of interelectrode voltage, near space electric field intensity wire increases gradually.Conventionally in free space, due to radiation, in every cc of air, nearly 1000 free electrons exist, and these free electrons, under the effect of electric field, can be accelerated, and clash into gas atom or molecule.The acceleration of free electron increases along with the increase of electric-field intensity, and the energy that free electron accumulates before clashing into gas atom or molecule also increases thereupon.When electric-field intensity reaches the threshold of gas discharge, the energy that free electron accumulates before shock will be enough to go out an electronics from gas atom or molecules strike.Now near wire, an air among a small circle starts ionization, has occurred the non-self-maintained discharge of gas.Continue boosted voltage, ionisation of gas will aggravate, and form a large amount of electron avalanches, produce a large amount of electronics and negative ions.
Ion generator 7 utilizes principle of corona discharge electron emission, and an electron is negatively charged lotus forms negative molecular ion with airborne neutral molecule.Negative molecular ion attracts neutral molecule, forms charged molecule compound, i.e. so-called light ion; Nearly 100 of the molecular amounts that this compound comprises, diameter is between 10-8 is to 10-7 centimetre.It is reported, the molecular ion containing in moisture laden air can form solvation ion (group) immediately, and the molecular ion that each solvation ion (group) contains is surrounded by 5 to 7 hydrones.Because hydrone is a kind of strong dipole, solvation ion cluster accelerates the reaction condition of anion and near the electronegative ion in ground.
After ion generator 7 is activated, the anion surface water steam-condensation in fog-zone, and motion with the wind around.This situation is accompanied by the factors such as superheated, rising and another burst of ionization airstream suction of local air, the output latent heat of vaporization.Ion generator 7 moves for a long time, generates strong stable space convection current (rising) air-flow.The suitable decline dry gas stream of (5-10 km) volume rises with the wind at a distance, and to cross-ventilation, motion compensates.Because self temperature is than around temperature is high, down current significantly evaporates water droplet, disperses with the wind showy mist vapour.
In the inlet scoop 12 of horizontal machine 9, water-absorbing resin 10 is installed, utilizes water-absorbing resin 10 to adopt the method for physical absorption, eliminate the moisture in fog, reach the object of preliminary fog dispersal; Four inlet scoops 12 of installing can guarantee that the mist of fog-dissipation device surrounding can evenly be eliminated; Fan 11 is delivered to ion generator 7 inside air-flow, impels the anion of generation to propagate into wider region around, greatly improves operating efficiency and the elimination fog effect of device.
In general local atmospheric situation, modal is radiation fog, and radiation fog makes ground condensation of moisture and forms by terrestrial reference radiation is cooling.Describe the detailed process that realizes arrtificial fog dissipation below in detail:
The ion generator 7 that this project technology is installed discharges negatively charged ions in atmosphere, crosses and reacts with atmosphere moisture, tentatively reduces the concentration of mist.In ion and hydrone interaction process, ion moves upward, and forms ascending air; Dry warm air air descend, cancels each other when two strands of air-flows meet, and the dry current of warm air of decline is eliminated mist in equipment sphere of action.Ion generator 7 continuous firings increase the ion concentration of surrounding environment, and its sphere of action also extend outward gradually, and mist disappearance region also expands thereupon.
Along with the continuity of time, the amount of ions being injected in atmosphere increases greatly, and this process has been strengthened the effect of demist, is not only near equipment, and farther region effect is also obvious gradually; The final beneficial effect of this technology is that the effect by ion generator 7 produces cross-ventilation and moves, and disperses all showy mists within the scope of effective coverage.
No matter mist is advection fog or radiation fog, is conventionally accompanied by the appearance of temperature inversion and occurs, in the height of 200 meters to 300 meters, inversion layer is also the reason place that mist is produced.In inversion layer, compared with warm and light air, be positioned at compared with above cold and heavy air, form a kind of extremely stable air layer, as same, throw the net, shroud the overhead at surface layer, seriously hamper the convective motion of air.Ion generator 7 constantly discharges electronics, and air is constantly heated, and creates stable convection current, and the motion of lasting convection current changes inversion layer position, thickness reduction when inversion layer rises.Final inversion layer breaks, and the temperature under inversion layer has reached the temperature on inversion layer, and along with the increase of convection current intensity, the vertical cloud generating has wiped out inversion layer, makes ground moisture laden air climb to altitude, thereby increases visibility, realizes complete demist.
This fog-dissipation device adopts local atmosphere situation influence technique, utilizes cross-ventilation motion to disperse with the wind in the whole process of showy mist vapour, and the time needing is not from 20 minutes to 90 minutes etc.Depend primarily on following factor: the three-dimensional development situation of the Formation and characteristics of mist, mistiness degree, mist, the meteorologic parameter of atmosphere and this area's landform.Can take different technology according to dissimilar mist---destroy inversion layer or downdraught positioning mode.According to regional shape and scope, decide quantity and the laying method of desired ion generator.For the concentration of mist, select corresponding operator scheme.
Ion generator 7 adopts ionization energy controlling technology, by formulating interval plan running timetable, avoid producing excessive ozone and byproduct thereof, greatly the minimizing of degree the harm to the mankind and animal health, and eliminated the destruction of corona discharge to equipment surrounding enviroment and infrastructure, not only environmental protection but also safe and reliable.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
