A kind of VOC organic waste gas treatment method of the present invention, comprises the following steps:
S1, generate multiple nanometer moisture film air bubbles; The method for generation of nanometer moisture film air bubble nanometer moisture film sky as described in the present inventionThe method for generation of bubble, or adopt the generating means 4 of nanometer moisture film air bubble of the present invention to generate multiple nanometer moisture film airBubble.
S2, VOC organic exhaust gas is led to nanometer moisture film air bubble, make described nanometer moisture film air bubble and described VOC organic uselessGas phase contact; The VOC pollutant of described VOC organic exhaust gas is by the moisture removal of described nanometer moisture film air bubble. Wherein, quiltThe hydrone of described nanometer moisture film air bubble is removed, and can be specifically Adsorption, dissolving removal, precipitation reaction removal etc. PlaceGas after reason is away from described nanometer moisture film air bubble.
In order to make the treatment effect of waste gas better, make above-mentioned processing method based on space be positioned at a casing, specific as follows:
In step S1, in the casing with air inlet 53 and gas outlet 54, generate multiple nanometer moisture film air bubbles;
In step S2, waste gas is passed in described casing from air inlet 53; Described gas after treatment is from discharge gas outlet 54In environment.
VOC organic waste gas treatment method of the present invention is the VOC VOCs treatment side based on nanometer moisture film air bubbleMethod.
VOC organic exhaust gas is a kind of active volatile organic matter, its molecular diameter one thousandth nanometer to one of percentage nanometer itBetween. After nanometer moisture film air bubble contacts with VOC organic exhaust gas, less VOC organic exhaust gas particle will be by nanometer moisture film skyThe Water Molecular Adsorption of bubble surface; And, when compressed air and hydrone overflow from the pore of hollow ceramic wafer, formIt has charging property nanometer moisture film air bubble, diffusivity, and the physical characteristics such as strong adsorptivity, band negative ion electrospray, can have with VOCPositive charge carrier in machine waste gas neutralizes, cohesion, precipitation. When increasing VOC organic exhaust gas particle is adsorbed on same, nanometer moisture film air bubble will drop at case because self proportion exceedes airborne suspension when on individual nanometer moisture film air bubble the surfaceBody. If (as be shown in the examplesly carry out in casing, because VOC organic exhaust gas constantly enters in casing, casing is for relatively closeSo the space VOC organic exhaust gas of envelope and nanometer moisture film air bubble can fully stir in casing, just can make two kinds of particle tablesFace fully contacts. ) and VOC organic exhaust gas obtains processing and becomes clean air and come back in air again.
In the time that the nanometer moisture film air bubble falling is stored into certain amount, due to VOC molecule and cohesion all little than hydrone density,So all swim in the water surface, and lower layer of water is clean water. The VOC on upper strata can reclaim processing and utilizing more so, and cleanWater also can recycle. Thereby make VOC organic waste gas treatment method of the present invention energy-conserving and environment-protective, energy consumption and cost is low,Treatment effect is good.
A kind of VOC organic waste gas treatment method example of the present invention is visible: methyl alcohol is VOC organic exhaust gas soluble in water,When the nanometer moisture film air bubble producing is enough in a large number time, allow each methanol molecules in motion process can be by nanometer moisture film skyBubble absorption, dissolves, and even the multiple of nanometer moisture film air bubble quantity in the time of motion contact exceeded methyl alcohol, that stephanoporate thin wall potteryThe nanometer moisture film air bubble that porcelain produces just can reach the effect of processing completely at processing methanol waste gas. And for example benzene, dimethylbenzene is at waterThe solubility on surface is 0.2mg/L, and when the specific area of water is increased to 10000 times, the water of 1L can dissolve more VOCOrganic exhaust gas molecule.
Consult the of the present invention a kind of VOC organic waste gas treatment device shown in Fig. 4, comprising:
The generating means 4 of nanometer moisture film air bubble of the present invention, in Fig. 4, the meaning of D, E instruction is identical with Fig. 3.
Treating apparatus casing 5, treating apparatus casing 5 is provided with air inlet 53 and gas outlet 54; The inner chamber for the treatment of apparatus casing 5 dividesFor upper cavity 51 and lower chamber 52. Air guide through hole is located at the sidewall of described treating apparatus casing 5. Hollow ceramic plate group 6 is located atThe upper cavity 51 of described treating apparatus casing 5, the quantity of hollow ceramic plate plate can be according to the amount of the VOC organic exhaust gas of processingDecide.
In lower chamber 52, be provided with water filtering device 7, described water filtering device 7 can be ceramic filter membrane device, corresponding water filtrationDevice 7, the sidewall of lower chamber 52 is provided with delivery port 55; Outlet and the lower chamber of the water after the derivation of water filtering device 7 is filtered52 delivery port 55 joins and communicates.
Lower chamber 52 is provided with for making water in lower chamber 52 guide to the water that water device reuses and follows device.
Water follows device and comprises: a mozzle, the first port of mozzle is communicated with the delivery port 55 of lower chamber 52, mozzleThe second port is connected with water device; The first port of mozzle is provided with valve, and mozzle is provided with water pump; Lower chamber 52 is also provided withOne is communicated with the inner and extraneous window of processing device box 5.
The use principle of VOC organic waste gas treatment device of the present invention:
First start the generating means 4 of nanometer moisture film air bubble, generate multiple nanometer moisture film air bubbles. Due to every block of hollow ceramic plateOn have a lot of pores, be all covered with nanometer moisture film air bubble on every hollow ceramic plate surface; Hollow ceramic plate group 6 have more inWhen empty ceramic wafer, can form a space that is covered with nanometer moisture film air bubble, in this space, have a large amount of nanometer moisture film air bubble energyRealize sufficient VOC VOCs treatment.
From air inlet 53, in treating apparatus casing 5, (what Fig. 4, indicate F instruction is VOC organic exhaust gas to VOC organic exhaust gasFlow direction), VOC organic exhaust gas enters the space that is covered with nanometer moisture film air bubble, now the VOC in VOC organic exhaust gasMolecule reacts and generates cohesion, precipitation by Water Molecular Adsorption or with hydrone; Thereby VOC organic exhaust gas obtains processing and becomesClean air also comes back to air from gas outlet 54. And nanometer moisture film air bubble is owing to having adsorbed VOC molecule or having comprisedPrecipitation, when nanometer moisture film air bubble weight reach one timing, it can fall to lower chamber 52, as the G in Fig. 4; Work as nanometerMoisture film air bubble continues to fall to lower chamber 52, in lower chamber 52, has certain water yield, as the H in Fig. 4. Due toVOC molecule and precipitation are all little than hydrone density, so VOC material all swims in the water surface, and that lower layer of water is the first order is dryWater purification, first order clean water can enter water filtering device and again be filtered, thereby obtains second level clean water. To down by windowThe surface mass of cavity 52 separates away, then opens valve and water pump, by the second level clean water guiding spray dress of lower chamber 52Put, thereby realize the circulation of water, the direction that can consult the I arrow in Fig. 4.
Guide to spray equipment and reuse in order to realize water in lower chamber 52, can also realize by following structure:
