Description
Technical field
The present invention relates to a kind of waste gas purification technique.
Background technology
Waste gas refers to the poisonous and hazardous gas that the mankind discharge in production and life process.Particularly chemical plant, steel
Factory, pharmaceutical factory, and coking plant and oil plant etc., the exhaust gas smell of discharge are big, severe contamination environment and influence health.Spin
It is the place for making cloth to knit factory, and not making can produce substantial amounts of waste water and gas, and waste water can also produce waste gas, these waste gas
Smell is heavy and also toxic, so we are required to the method for purifying waste gas.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of waste gas purification effect it is good, clearance is high, processing mode
Easy waste gas purification technique.
To achieve the above object, technical scheme：
A kind of waste gas purification technique, including activated sludge tank, oxidizing tower, caustic wash tower, air-introduced machine, exhaust tube, described activity are dirty
Waste water station waste gas is passed through in mud sump, activated sludge tank temperature is maintained between 10 degrees Celsius to 50 degrees Celsius, and needs to carry out 24
Hour reaction, activated sludge tank can purification gas, reduce the content of organic matter and noxious material in waste water station waste gas, then give up
It is the sodium hypochlorite of 0.8mg/L that water station waste gas is passed through in oxidative absorption tower, oxidative absorption tower and adds concentration, by circulating pump circulation
Contact 25 minutes, alkali adsorption tower is being passed through by waste water station waste gas, is contacted with the alkali lye in alkali adsorption tower, by circulating pump and alkali lye
Circulating contact 25 minutes, thus after air-introduced machine is by waste water station exhaust-gas treatment can discharge gas be led to that exhaust tube is arranged
Put, discharge drum height of release is 15 meters.
Preferably, the toxic component of described waste water station waste gas has NH-N3 and H2S.
Preferably, described oxidative absorption tower is recycled to waste water station again with the waste water produced by alkali adsorption tower carries out dirt
Water process.
Beneficial conditions of the invention are：Waste gas purification effect is good, and clearance is high, and processing mode is easy.
Brief description of the drawings
Fig. 1 is artwork of the invention.
Specific embodiment
As shown in figure 1, a kind of waste gas purification technique, including activated sludge tank, oxidizing tower, caustic wash tower, air-introduced machine, air draft
Cylinder, is passed through waste water station waste gas in described activated sludge tank, activated sludge tank temperature be maintained at 10 degrees Celsius to 50 degrees Celsius it
Between, and need to carry out the reaction of 24 hours, activated sludge tank can purification gas, organic matter and Toxic in reduction waste water station waste gas
The content of matter, it is the hypochlorous acid of 0.8mg/L that then waste water station waste gas is passed through in oxidative absorption tower, oxidative absorption tower and adds concentration
Sodium, by circulating pump circulating contact 25 minutes, alkali adsorption tower is being passed through by waste water station waste gas, is connect with the alkali lye in alkali adsorption tower
Touch, by circulating pump and alkali lye circulating contact 25 minutes, so that by air-introduced machine by the discharged gas after waste water station exhaust-gas treatment
Body is led to that exhaust tube is discharged, and discharge drum height of release is 15 meters.
Preferably, the toxic component of described waste water station waste gas has NH-N3 and H2S.
Preferably, described oxidative absorption tower is recycled to waste water station again with the waste water produced by alkali adsorption tower carries out dirt
Water process.
Waste gas purification effect of the invention substantially reduces well the content of pernicious gas in waste gas, the pernicious gas after treatment
Content is as shown in the table：
| Detection project | Absorption tower import | Absorption tower exports | Execution standard | Clearance（%） |
| NH-N3 discharge capacitys（kg/h） | 0.00426 | 0.00152 | ≤0.0049 | 62.3 |
| H2S discharge capacitys（kg/h） | 0.000119 | 0.000035 | ≤0.00033 | 71.8 |
| Odor concentration（Without steel amount） | 1738 | 835 | ≤2000 |
It should be understood by those skilled in the art that, the present invention is not limited to the above embodiments, in above-described embodiment and specification
What is described merely illustrates the principles of the invention, and without departing from the spirit and scope of the present invention, the present invention also has various
Changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by institute
Attached claims and its equivalent thereof.
