During specific use, we find during the use, because the nanometer bubble that aeration head 5 produced gives off for some, lead to keeping away from aeration head 5 regional nanometer bubble's density lower, make this regional organic matter degradation effect relatively poor, stirring shaft 14 has consequently been set up, under the effect of air current, the fan rotates, thereby it is rotatory to drive impeller 15 through stirring shaft 14, stir the water of both sides when impeller 15 is rotatory, make the water of central point position shift to limit portion, thereby shift nanometer bubble to limit portion, thereby improve the nanometer bubble density in the region of keeping away from aeration head 5, the organic matter degradation speed in this region has been improved.
A method for treating organic waste gas by adopting the organic waste gas treatment system comprises the following steps:
s1, injecting water into an inner cavity of a treatment tank 1, then opening a nano bubble generating device 4, and dispersing nano bubbles generated by the nano bubble generating device 4 into the water through an aerator 5;
s2, injecting organic waste gas into the air inlet connecting pipe 101 through the air inlet pipeline 2, and then dispersedly spraying the organic waste gas out through the dispersive air outlet device 7;
s3, opening a gas-liquid mixing pump 11, dissolving air into water by the gas-liquid mixing pump 11, pumping the gas-dissolved water into a water tank 6 through a spraying pipeline 10, spraying the gas-dissolved water in the water tank 6 through a spraying head 8, enabling water drops sprayed by the spraying head 8 to absorb pollutants in the organic waste gas and then fall into the water, and degrading the organic pollutants through nano bubbles in the water;
s4, discharging the gas with the pollutants removed through the air outlet channel 602 and the air outlet pipeline 3.
The working principle is as follows: firstly, injecting water into the inner cavity of a treatment tank 1, then opening a nano bubble generating device 4, dispersing nano bubbles generated by the nano bubble generating device 4 in water through an aeration head 5, injecting organic waste gas into an air inlet connecting pipe 101 through an air inlet pipeline 2, then dispersing and spraying the organic waste gas through a dispersing and air outlet device 7, opening a gas-liquid mixing pump 11, dissolving air into the water by the gas-liquid mixing pump 11, pumping the dissolved air water into a water tank 6 through a spraying pipeline 10, spraying the dissolved air water in the water tank 6 through a spraying head 8, making water drops sprayed by the spraying head 8 fall into the water after adsorbing pollutants in the organic waste gas, degrading the organic pollutants through the nano bubbles in the water, discharging the gas without the pollutants through an air outlet channel 602 and an air outlet pipeline 3, when spraying, under the action of water pressure, a support 91 moves downwards, the support 93391 drives a top column 933 to move downwards through a connecting column 931, make fore-set 933 and apopore 801 separation, water passes through apopore 801 blowout, and simultaneously, under the effect of rivers, drive impeller 932 rotates, thereby it is rotatory to drive fore-set 933 through spliced pole 931, after the fore-set 933 is rotatory, the water droplet that falls to the fore-set 933 surface can fly away, make the dispersion effect of water droplet better, the contact probability of the discarded object in water droplet and the organic waste gas has further been improved, when not spraying, under elastic supporting device 92's spring action, support frame 91 rebound, the fore-set 933 inserts gradually in the apopore 801, thereby the apopore 801 mediation that will be blockked up is opened.
