It becomes the more easily substance by liquid absorption；Third, after fine particulate contaminants in air-flow are charged, it is easier in bubble
It is interior to be adsorbed and removed by liquid surface；4th, if having electric field arrangement one before bubbling board, the electric field generated on silk screen can promote
Into the interaction of charged bubble and liquid；5th, the active group of electric field arrangement release can be to the pollution in liquid
Object is handled.
The present apparatus may also include the vibration machine being installed on the bubbling board, generates vibration and makes gas on bubbling board
Bubble is generated and is more uniformly distributed, smoothly, while can also clean blistering mouth.
The present apparatus may also include the vibration machine being installed on mesh pad, generate vibration so that silk screen is preferably cut
It cuts, disturb bubble it is made to be mixed with liquid.
The present apparatus may also include the cooling system for controlling fluid temperature.On the one hand the cooling system ensures the steaming of liquid
Hair amount is in reduced levels, on the other hand the steam in bubble can be made to occur to condense to purifying gas flow simultaneously using cold liquid
Recycle moisture.
The present apparatus may also include the sonic generator being installed in cavity, generates acoustic vibration and makes bubble on bubbling board
Generation is more uniformly distributed, smoothly, while can also clean blistering mouth.
It further includes the surfactant made an addition in liquid that the present apparatus, which may also include,.
The present apparatus may also include the adsorbent for pollutant in gas made an addition in liquid.
Compared with prior art, the present invention includes following advantages：
The blistering of the present invention is by means of the blistering mouth of protrusion, and compared to common tablet sieve pore, bubble is detached from blistering mouth more
It is easy, while the bubble that two neighboring blistering mouth generates is less susceptible to merge.Ensure that the size of bubble will not be excessive.
Bubble deforms with mesh pad effect in liquid after generating, divides, slows down, these effects are so that gas-liquid
There is better contact.Mesh pad ensure that high efficient gas and liquid mixes with the cooperation of blistering mouth.
Further, the present invention can make bubble be more readily pulled from blistering mouth by the vibration of bubbling board.Bubbling board
Simultaneously also so that the blister formation of different location is uniform, whole required blistering resistance reduces for vibration.
Further, the present invention further improves interaction of gas and liquid and can change to pollutant by introducing electric field arrangement
Property.
By improving above, the present invention has significant enhancing efficiency compared to traditional Bubbling method, and can handle and contain
There are many air-flows of pollutant for including desulphurization and denitration, dedusting, demercuration, removing formaldehyde, except VOC etc..
