Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tunnel except haze system.
Detailed description of the invention
Describe embodiment below in conjunction with accompanying drawing and concrete elaboration is done to the utility model.
As Fig. 1, a kind of tunnel is except haze system, comprise the blower fan that is arranged at tunnel inner wall and except haze device, nozzle 1 should be comprised except haze device, water pump 2, store water tank 3 and the air compressor machine 4 of water, the port of export of this water tank 3 connects water pump 2 by pipeline, the port of export of water pump 2 and the port of export of air compressor machine 4 are connected the entrance point of nozzle 1 with Y word pipe 5, flow control valve 6 and mass air flow sensor 7 is provided with between the port of export of air compressor machine 4 and Y word pipe 5, water ga(u)ge 8 is provided with between described water pump 2 and Y word pipe 5, the compressed air produced with air compressor machine 4 under the effect of water pump 2 when the fluid media (medium) of 3 li, water tank sprays from nozzle 1 after Y word pipe 5 mixes.According to mass air flow sensor 7 and water ga(u)ge 8 monitored data, by control flow check adjustable valve 6 to control concentration and the spouting velocity of spraying, such adjust flux size is to form different sprayings.Pipeline in the present embodiment and Y word pipe 5 all adopt pvc pipe.
The nozzle 1 adopted in the present embodiment is that the atomization of liquid can spray by one, and a kind of device of even suspension in air.Its operating principle passes through internal pressure, enter in nozzle 1 by the extruding of the liquid of inside, nozzle 1 inside is placed with one piece of iron plate, and swiftly flowing liquid knockout is on iron plate, form the atomizing particle of diameter about 15-60 μm after bounce-back, and export ejection by nozzle 1.The aperture of this nozzle 1 spray orifice is 1-3mm, and the spray orifice of nozzle 1 is less, and jet is thinner, is atomized thinner, certainly can set the size in aperture here according to actual needs, is generally set as that 1-3mm is comparatively economic, suitable size.
The compressed air produced at the water of deriving through water pump 2 from water tank 3 and air compressor machine 4 is at Y word pipe 5 mix and blend, due to may compressed air etc. be mingled with in the Aerodynamic force action of jet turbulence, ambient gas, water, current are made to produce distortion, particularly under Pneumatic pressure and surface tension effects, areal deformation is constantly aggravated, so that current produce division, form the water droplet of water smoke or instability, water droplet is also broken into water smoke thereupon.If (active force acted on water droplet is quite large, and when being enough to overcome surface tension, water droplet will be broken into less water smoke, and this phenomenon is called " secondary-atomizing ".So-called secondary-atomizing, when referring to that the water droplet formed after jet separation moves compressed air, continues to split into more tiny water droplet phenomenon.)
During the motion of water droplet in gas, be mainly subject to the effect of two kinds of power: Pneumatic pressure, water droplet be out of shape broken; Surface tension, makes water droplet remain stationary.When water smoke diameter is comparatively large, when moving very fast, Pneumatic pressure just may be greater than surface tension, and droplet is deformed, and then splits into less droplet.The aerodynamic force condition that secondary breaks required can represent with Weber number.The physical significance of Weber number is Pneumatic pressure and the ratio of water surface tension, water starts to be out of shape, broken time Weber number be called critical Weber Number.When being greater than 14, water droplet is all broken for water smoke.Weber number is larger, and water smoke is thinner.The spray orifice of nozzle 1 is less, and jet is thinner, is atomized thinner.Nozzle 1 pressure drop is larger, and the exit velocity of jet is larger, and thus turbulence level and Weber number are just large, is conducive to breaking of jet and water smoke, favourable to atomization.General water at normal temperatures surface tension is 7.0-7.5x10 -2n/m is 0.7-2.0MPA in air compressor machine 4 setting pressure described in the utility model is comparatively suitable, economical.The pressure of certain air compressor machine 4 according to different environment, can change as the difference according to water temperature.
Water is in atomization process simultaneously, and due to the mutual high-speed impact effect between hydrone, (under normal circumstances, air molecule shows electroneutral to produce a large amount of oxonium ions containing negative electrical charge.And namely the idea affinity of various gas capture the ability difference of free electron in air, oxygen, carbon dioxide are far longer than other gas.Calculate by unit volume, the aerial content of oxygen is generally 20.9%, is 700 times of carbon dioxide 0.03%.Therefore the anion rhymed formula major part generated in air is all negative oxygen ion), a large amount of negative oxygen ions can adsorb and assemble and has more outstanding binding ability, makes it to become depositing dust.Negative oxygen ion, owing to adding an outer-shell electron, obtains negative electrical charge.Negative oxygen ion has outstanding binding ability, makes usually all positively charged dust, smog, germ, virus mutually assemble, neutralize, loses the ability of free-floating in atmosphere, and fall rapidly, no longer form harm to human body, thus purified air.
