Description
Technical field
The present invention relates to a kind of catalysis high-pressure decomposing reactors for handling industrial waste gas, belong at the exhaust gas in environmental protection
Reason field.
Background technique
Atmosphere pollution is China's one of environmental problem most outstanding at present, and volatile organic waste gas is the weight of atmosphere pollution
Want source.With the fast development of China's Petrochemical, the volatile organic waste gas that is discharged into production process in atmospheric environment
Also it is being continuously increased, these pollutants mainly include arene compound (benzene homologues), aldoketones, halogenated hydrocarbons, alcohols etc..Its
In, the discharge amount of arene compound is relatively large, and it is again relatively prominent to the harm of ecological environment and human health, therefore,
The purified treatment of arene compound is increasingly valued by people.
Since the volatility of arene compound is very strong, it is exposed to and is easy to spread in air.Humans and animals pass through sucking
Or the aromatic hydrocarbon of skin contact excess intake, acute and chronic benzene poisoning can be caused.There is research report to show to cause benzene poisoning
Phenol is generated in part because of intracorporal benzene.Benzene meeting Central nervous system generates paralysis effect, causes acute poisoning.
Severe one will appear headache, Nausea and vomiting, in a certain state of delirium, unconsciousness, stupor, twitch, even death；A small amount of benzene can also make one
Sleepiness is generated, giddy, increased heart rate, has a headache, tremble, Bewu βtseinstrubung, the symptoms such as obnubilation.Normal person sucks 20000ppm's
It will be in peril of one's life within benzene vapour 5 ~ 10 minutes.
Long Term Contact benzene can cause great damage to blood, cause neurasthenia syndrome.Benzene can damage marrow, make red
Blood cell, leucocyte, platelet counts are reduced, and make chromosome aberration, and so as to cause leukaemia, or even aplastic occur poor
Blood.Benzene can cause to bleed profusely, to inhibit the function of immune system, disease be made to have an opportunity to take advantage of.There is research report to point out, benzene
It is in intracorporal incubation period 12 ~ 15 years in people.
Currently, the production. art process and exhaust gas discharging modes of China's Petrochemical enterprise are different, exhaust emission control
Technology processed is also far from each other.In general, the processing method of the wide use in China mainly has: absorption method, heat damage method, cold
Solidifying method, absorption process etc..
(1) absorption method:
With porous solid treatment fluid mixture, one or more of components contained therein is made to be enriched in the surface of solids, and with
The process of other component separation is known as adsorbing.Absorption method is mainly used for the purification of low concentration high throughput aromatic hydrocarbon.
(2) heat damage method:
Heat damage method is current application than aromatic hydrocarbon administering method wide, that research is more, especially suitable for containing low concentration
The exhaust gas of aromatic hydrocarbon.This method can be divided into direct flame combustion and catalysis burning, and process is complicated and may include a series of
Decomposition, polymerization and radical reaction.And most important aromatic hydrocarbon heat damage method mechanism includes oxidation, thermal cracking and thermal decomposition, heat
Destruction method is based on the progress of this mechanism.
(3) condensation method:
Condensation method is that have this property of different saturated vapor pressures at different temperatures using substance, using reduce system temperature or
System pressure is improved, the process for condensing the aromatic hydrocarbon in steam condition and separating from exhaust gas.
(4) absorption process:
The characteristics of absorption process can mainly be dissolved each other using aromatic hydrocarbon with most of oily substance, with the oils of higher boiling, low-steam pressure
The aromatic hydrocarbon in exhaust gas is absorbed as absorbent, common absorber is padding washing absorption tower.
(5) biofilm:
Microorganism is exactly fixedly attached to porous medium filler surface by so-called biofilm, and makes polluted gas in packed bed
Biological treatment is carried out in layer, can be by contaminant removal therein, and be allowed to degrade in gap.Volatile organic contaminant is inhaled
It is attached to apparent gap, is consumed by the Institute of Micro-biology in gap, and be degraded into CO2、H2O and neutral salt.
Currently, the aromatic hydrocarbon waste gases processing method that China generallys use, generally existing initial investment is big, operation and maintenance cost
High, the disadvantages of technology is complicated, and its treatment effect is also difficult to meet increasingly strict emission request.For this reason, it may be necessary to find new
Method and approach solve this problem.
