In gas-liquid mixing pump 34, the oxygen and ozone that gas input 36 receives are compressed and are mixed into water body, water body
Dissolved oxygen amount and molten ozone amount be rapidly reached supersaturation, solubility of the ozone in water is about 10 to 15 times of oxygen molecule, portion
Divide unnecessary gas to form micro-nano bubble to be mixed into water body.1 micron of 100 a ten thousandth equivalent to 1 meter, and nanometer is
It is millimicron, 1 nanometer equivalent to 1/1000000000th meter.Micro-nano bubble, which represents bubble size distribution, micron order size, also
Have close to nano-grade size.The exit of gas-liquid mixing pump 34 connects pressure adjustment tank 40, and its top is connected to pressure regulation
Valve 42, water adjusts the outlet of tank 40 through excess pressure, and a part of water 44 flows to lower air conduit 16 by the road, through the spray water of first jet 46
Drop in lower air conduit 16.Another part water 48 is flowed in spray chamber 20 by the road, and water droplet is sprayed through second nozzle 50.
The flue gas produced when workshop is through ventilation duct 12, air exhauster 14, and when reaching lower air conduit 16, the sprinkling of first jet 46 contains
The water droplet of dissolved ozone and ozone bubbles, cigarette ash meets water droplet, because the electricity price potential difference of ozone produces absorption, cigarette ash can be sticked to
Water drops surface, is subsequently collected in pond.The flue gas of discharge continues to push ahead, and enters spray chamber 20 from the resilience of water face.Together
The reason of sample, the water droplet that second nozzle 50 sprays, because the reason containing ozone and ozone bubbles can adsorb cigarette ash, the cigarette after processing
Gas, wherein cigarette ash are reduced and aqueous vapor increases, and continuation is discharged to air from chimney 22 forward.Therefore the micro-nano energy of ozone emission-reducing system 10
The cigarette ash and other dirts in flue gas are adsorbed, the direct discharge of cigarette ash is reduced.
As shown in figure 1, the flue gas that ventilation duct 12 is come in is adsorbed substantially across three roads.First of absorption is in first jet
The spray region formed at 46, second absorption is, to water face, to be attracted to the water surface in smoke contacts.3rd road absorption be
The spray region formed at second nozzle 50.Some cigarette ashes contain unsaturated hydrogen bond, there is peculiar smell.By the absorption in three roads, cigarette is reduced
Cigarette ash in gas, including containing unsaturated hydrogen bond, long key oiliness thing and possible sulfide.Therefore micro-nano ozone emission-reducing system 10
It can also go to eliminate the unusual smell while smoke evacuation can be reduced.The present embodiment selection has used above-mentioned three road suction type and its corresponding useless
The micro-nano structure of ozone emission-reducing system 10 of gas.It is of course also possible to using only first of the absorption of first jet 46 and water surface absorption
Second adsorbs the micro-nano ozone emission-reducing system structure of twice suction type and its corresponding waste gas；The water surface can also be used only

Water in pond 18, can attract the dirt in water because of ozone valency containing negative electricity, particularly there is unsaturated hydrogen bond
Cigarette ash easily attract each other.The cigarette ash adsorbed by ozone, during ozone and oxygen molecule decomposition, cigarette ash is from macromolecular shape
Formula is broken into small molecule form, and the cigarette ash of small molecule form is further aoxidized, and eventually becomes carbon dioxide and water.To make
Easily distribution shift and a variety of different size of dirts form oxidation reaction, recirculated water to bubble containing ozone and oxygen in pond 18
The size distribution for including ozone bubbles is major consideration.The bubble that bubble ratio ozoniferous is constituted with general air, which reacts, lives
Property is many by force.When ozone bubbles are 1 grade sizes, bubble can only be stopped the several seconds in pond internal cause buoyancy relation, it is impossible to
Obtain in effect ground oxidation reaction.Bubble can be stayed in pond and drifted about in 1-0.1 micron order sizes, and the residence time is about more than ten point
Clock.Bubble is in super micron-scale, i.e., close to 0.001 micron order size, and the time drifted about in pond can be rested in theory more
Long, but because molecular structure water also polarized, ozone in itself easily accelerates to fail into oxygen molecule, the activity of bubble is reduced.Generally
Half-life period of the ozone in water body about at 20 minutes, therefore adjustment ozone bubbles Size Distribution in 0.01-1 micron order sizes,
It is preferred that size distribution ranges be 0.05-1 micron order chis, can maintain the reactivity of ozone bubbles, accelerate pollutant in water body
Decomposition, and preferable ozone bubbles distribution chi can be had by suitably debugging the pressure-regulating valve 42 for adjusting the top of tank 40 positioned at pressure
It is very little, experiment display, the pressure of pressure-regulating valve 42 is in 0.1Mpa to 0.3 Mpa, and scope preferably is 0.1 Mpa to 0.25
Mpa, the ozone bubbles size distribution that this pressure limit is produced can relatively efficiently decompose the dirt in water body.

Micro-nano ozone emission-reducing system 10 can be adsorbed outside above-mentioned acid mist, alkali mist and paint waste gas, can also adsorb non-hydrophilic
Cigarette ash, grease-contained flue gas is produced in many industry production processes, because water droplet includes ozone, makes the cigarette ash of original non-hydrophilic
It can be adsorbed by water droplet, reach the effect that tradition elution operation does not reach.
The micro-nano ozone emission-reducing system 10 of waste gas described in the utility model embodiment and traditional direct in pond 18
Ozonation aerated comparison is advantageous.Because under certain pressure, temperature, concentration, molten ozone amount is limited in water body, is often far below
Absorption and the demand for decomposing cigarette ash.The water droplet of water droplet containing dissolved ozone and ozone bubbles and only dissolved ozone compares, excellent
Gesture is obvious.Because the overall electricity price position of ozone bubbles is shown on bubble chamber film, and hydrone polarized itself, this has whole water droplet
The electricity price position performance of body is stronger than the water droplet of only dissolved ozone.And ozone is stored in water body with micro-nano bubble form,
It can substantially increase to soot-treating capacity, reach traditional directly ozonation aerated effect not reached.
