Abstract
The invention relates to the technical field of waste gas treatment, in particular to a waste gas treating agent. The waste gas treating agent comprises by weight, 40-50 parts of papermaking black liquid, 10-20 parts of FeCl3, 5-15 parts of CuO, 7-18 parts of nano SiO2 and 3-12 parts of tannin. The waste gas treating agent can be used for treating multiple kinds of waste gas such as SO2, NO, CO2, CO, methanal, heavy metal and other substances, the papermaking black liquid which is a serious pollutant is comprehensively recovered and reutilized, waste materials are made profitable, and the production cost of products is greatly reduced. The waste gas treating agent is suitable of treating industrial waste gas and automobile exhaust.
Description
Technical field
The present invention relates to technical field of waste gas treatment, particularly a kind of exhaust gas treating agent.
Background technology
Waste gas refers to that the mankind are at the poisonous and hazardous gas produced and discharge in life process.Particularly chemical plant, steel plant, pharmaceutical factory, and coking plant and oil plant etc., the waste gas smell of discharge is large, serious environment pollution and affect health.The industrial waste gas of all kinds of manufacturing enterprises discharge is the important sources of atmosphere pollution.If large capacity industrial waste gas unprocessed up to standard after enter air, atmosphere quality must be made to decline, bring serious harm to health, bring about great losses to national economy.After in industrial waste gas, poisonous and harmful substance enters human body by respiratory tract and skin, long-term low concentration or the contact of short-term high concentration can cause the temporary and permanent pathology of the organs and systems such as the breathing of human body, blood, liver, and especially benzopyrenes polycyclic aromatic hydrocarbon can make human body directly carcinogenic to cause the great attention of the mankind.
Industrial waste gas comprises organic exhaust gas and inorganic waste gases.Organic exhaust gas mainly comprises various hydro carbons, alcohols, aldehydes, acids, ketone and amine etc.; Inorganic waste gases mainly comprises oxysulfide, nitrogen oxide, oxycarbide, halogen and compound thereof etc.China takes pollutant emission control system for atmosphere pollution.Organic exhaust gas is one of main atmosphere pollution, enters human body, cause temporary and permanent pathology to organs and systems such as the breathing of people, blood, livers by respiratory tract and skin.As PTA oxidized tail gas contains a large amount of pernicious gases, as: formaldehyde, benzene,toluene,xylene, methyl acetate, CO etc., its index all exceedes discharging standards, causes serious harm to environment.For preventing pollution, except reducing oil loss, reducing consumption of organic solvent with except the generation reducing organic exhaust gas and discharge, exhaust gas purification is current practicable governance way.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of exhaust gas treating agent, and this exhaust gas treating agent applied range, can process multiple harmful exhaust.
For achieving the above object, the present invention adopts following technical scheme:
A kind of exhaust gas treating agent, be made up of the raw material of following weight portion:
For ensureing the superperformance of exhaust gas treating agent, preferably, black liquid Baume degrees of the present invention is 35 ~ 40 ° of B é.
Tannin of the present invention derives from persimmon.Tannin can Adsorption of Heavy Metal Ions, reduces heavy metal substance content in waste gas.
Preferably, exhaust gas treating agent of the present invention, be made up of the raw material of following weight portion:
Black liquid of the present invention contains a large amount of K
2cO
3, Na
2cO
3, KOH, NaOH and Ca (OH)
2deng, there is desulfidation, alkali wherein can also and CO
2reaction generates salt, thus removing CO
2.
FeCl
3the effect of catalyst can be played, reduce SO
2and NO, play absorbent again simultaneously.
Nano-meter SiO_2
2have very strong adsorption capacity, can adsorb the formaldehyde in waste gas, not only there is physical absorption in its PARA FORMALDEHYDE PRILLS(91,95), and has chemisorbed, defines hydrogen bond or covalent bond with formaldehyde, can be reduced the content of formaldehyde in waste gas.
The CuO that the present invention adds, can react with CO under high temperature and generate Cu and CO
2, thus removing CO, the CO of generation
2with the alkali reaction in black liquid, CO can be prevented
2enter in air.
The usage of exhaust gas treating agent of the present invention: waste gas is contacted with exhaust gas treating agent of the present invention.
Beneficial effect of the present invention is:
1, the present invention can process multiple harmful exhaust, as SO
2, NO, CO
2, CO, the material such as formaldehyde and heavy metal.
2, the black liquid synthetical recovery as high pollution thing is recycled, turn waste into wealth, greatly reduce the production cost of product.
3, the present invention forms simply, and process waste gas Be very effective, product of the present invention is applicable to industrial waste gas and vehicle maintenance service.
