Description
Technical field
The present invention relates to field of environment protection equipment, technology and dress is absorbed and utilized in specifically a kind of hypergravity zero-emission organic volatile
It sets.
Background technique
Volatile organic compounds (Volatile Organic Compounds, VOCs), refers to saturated vapor under room temperature
It presses greater than boiling point under 70Pa, normal pressure in 260 DEG C of organic compounds below, or vapour pressure is more than or equal at 20 °C
10 Pa have corresponding volatile whole organic compounds, have high vapour pressure, volatile organic chemicals, main to wrap
Aliphatic and aromatic various alkane, alkene, oxygen-containing hydrocarbon and halogenated hydrocarbons etc. are included, such as benzene, toluene, methylene chloride, formaldehyde, acetic acid
Ethyl ester etc..
China's industrial source VOCs discharge amount is about 1335.6 ten thousand tons within 2010, and wherein the production link of VOCs discharges VOCs about
It is 263.0 ten thousand tons, oil product and solvent storage and carrier have discharged 129.5 ten thousand tons of VOCs pollutants, using VOCs as raw material
Technical process discharges two 176.9 ten thousand tons, and the link that uses and discharge of the product containing VOCs then discharges 766.63 ten thousand tons.Petroleum refining
System, building decoration, mechanical equipment manufacture and printing are the forward four major trades of VOCs discharge amount, respectively accounting 17%, 16%,
11% and 7%.
" 13 " period, China will be included in the VOCs (volatile organic compounds) of ozone and the important arch-criminal of PM2.5
Emission reduction index is implemented respectively in certain key areas and key industry." the 12nd Environmental Health peace that reporter holds in Guangzhou
Recognize in full laws and regulations summit ", under economic development baseline Case, it is contemplated that the year two thousand twenty, the year two thousand thirty China's industrial source
VOCs discharge amount will be up to 2147.22 ten thousand tons, 3660.85 ten thousand tons.In order to control VOCs discharge, China has the catering trade, gasoline fortune
Defeated, petrochemical industry etc. 14 are related to the discharge standard of VOCs, are formulating including 18 VOCs such as agricultural, fuel, industrial coating
National emission standard;Guangdong also issued in 2010 Furniture manufacture, packages printing, external coating, shoemaking totally 4 to VOCs place
Discharge standard.
VOCs generally has stronger irritation and toxicity, partially have teratogenesis, carcinogenic, mutagenesis, suitable one
Divide the characteristics such as foul smelling, inflammable and explosive, there is very big security risk during production and transportation.Some chemistry are living in VOCs
Property is very strong, is one of the factor of causing optical smoke.Halogenated hydrocarbon VOCs can destroy ozone layer, and greenhouse effects etc. can be caused complete
Ball environmental problem.In short, the discharge of VOCs all produces significant damage to human body and biology health, ecological environment.
There is lasting serious haze weather in winter in recent years, the more ground in China, to people's life, physically and mentally healthy production
Significant damage is given birth to.The main reason for haze weather generates is the severe overweight of PM2.5 in air, and VOCs is PM2.5
One of guide's factor.In January, 2013 begins, and the environmental protection department of the key cities such as Beijing successively starts pilot monitoring PM2.5
And O3Concentration.Therefore, PM2.5 concentration is controlled, monitoring must be just paid close attention to VOCs and be reinforced and is administered.
In recent years, both at home and abroad for measurement and Treatment process have new progress.In VOCs measuring method, both at home and abroad
General gas chromatography-mass spectrography (GC-MS) is mostly used greatly.The proton translocation ionization-mass spectrometry method (PTR-MS) graduallyd mature because
It realizes the high-sensitivity analysis of VOCs and is widely adopted.In terms of administering VOCs, in traditional adsorption technology, catalysis burning skill
On the basis of art and heating power incineration technology, bio-filter technology, the emerging technology of plasma collapse innovation are also graduallyd mature.
VOCs processing technique used by China is at present to adsorb, be catalyzed burning, based on biological treatment, these three technologies
Occupation rate of market respectively reach 38%, 22%, 15%, from the point of view of comparison, in external (predominantly American-European countries) adsorption technology occupation rate
It is lower, it is number three position for 16%.In the case where being suitable for recycling VOCs, adsorption technology be it is a kind of it is economical, meet clean manufacturing
The selection of theory, therefore be widely used at home and abroad.And domestic many medium-sized and small enterprises selection adsorption technologies are to pursue it to build
If feature at low cost, there is no realize VOCs recycling and effective operation and maintenance.Biotechnology and catalytic combustion technology are in state
The outer second that ranks the first respectively, accounts for 29% or so.
Therefore, it in conjunction with above feature, needs to develop one kind VOCs processing at low cost, high treating effect and returns
Receiving unit.
