Method.
Background technique
Exhaust gas refers to the poisonous and hazardous gas that the mankind are discharged in production and life process.Especially chemical plant, steel
The generation of factory, pharmaceutical factory and coking plant and oil plant etc. and the brought life exhaust gas of human lives, the exhaust gas smell of discharge
Greatly, it seriously pollutes environment and influences human health.Many containing pollutant kind in exhaust gas, physics and chemical property are very multiple
Miscellaneous, toxicity is also not quite similar.Contain sulfur dioxide, nitrogen oxides, hydrocarbon etc. in the exhaust gas of fuel combustion discharge；Because of work
Industry production is raw materials used different with technique, and discharges a variety of different pernicious gases and solid waste, contains various components such as weight
Metal, salt, radioactive substance；The tail gas of motor vehicle emission contains the hydrocarbons such as lead, benzene and phenol.Exhaust emission atmospheric environment
It is one of the environmental problem of the most universal most serious in the world.Chinese " Law on Environmental Protection " to the waste gas emission standard of all kinds of factories and miness,
Specific regulation is made.Reprocessing becomes using product again after certain waste gas recoveries.
The industrial waste gas of all kinds of manufacturing enterprise's discharges is the important sources of atmosphere pollution.If big capacity industrial waste gas without
Handle it is up to standard after be discharged into atmosphere, necessarily decline atmosphere quality, bring serious harm to human health, made to national economy
At massive losses.After poisonous and harmful substance can enter human body by respiratory tract and skin in industrial waste gas, long-term low concentration or short
The contact of phase high concentration can cause the systems such as breathing, blood, the liver of human body and the temporary and permanent lesion of organ, especially benzene
And pyrene class polycyclic aromatic hydrocarbon can make the human body directly carcinogenic great attention to cause the mankind.
Industrial waste gas includes organic exhaust gas and inorganic waste gases.Organic exhaust gas mainly includes various hydro carbons, alcohols, aldehydes, acid
Class, ketone and amine etc.；Inorganic waste gases mainly include oxysulfide, nitrogen oxides, oxycarbide, halogen and its compound etc..
China takes pollutant emission control system for atmosphere pollution.
There are several types of (1) physical methods for existing waste gas processing method, proportionally mix two kinds of odorous gases,
To mitigate stench；(2) diffusion method is diluted, spreads foul smell with chimney, or the concentration that can be discharged is diluted to odorless air；
(3) odorant is condensed into liquid and removed by condensation method；(4) water absorption method absorbs exhaust gas with water；(5) absorption method, using work
The adsorbents such as property charcoal, silica gel, atlapulgite absorb exhaust gas；(6) chemical washing method adds NaClO, Cl2Equal oxidants,
By in foul smell organic sulfur and the substances such as organic amine be oxidized to stink compared with the light or higher compound of solubility, then with acid,
Alkali absorption purification；(7) combustion method, burn by exhaust gas at high temperature etc..In the above waste gas processing method, each method
Having advantage, there is also very big defects, can not fully meet the demand of reality.
