Description
Technical field
The present invention relates to a kind of VOCs cleaning systems of petrochemical industry waste gas, the exhaust-gas treatment neck belonged in environmental protection
Domain.
Background technology
VOCs is VOC（volatile organic compounds）English abbreviation.Typically
VOCs emission sources can be divided into anthropogenic discharge source（Including stationary source and moving source）With natural emission source（Including biological source with it is abiotic
Source）Two classes, wherein taking human as based on emission source, mostly for the production process of petrochemical industry related industry, product consumption behavior with
And motor-vehicle tail-gas causes.VOCs complicated component, the harm to human body is big, and possessed special odor can cause the kind of human body
Kind sense of discomfort, and there is toxicity and excitant.Known many VOCs have neurotoxicity, kidney and hepatotoxicity, or even have
Carcinogenesis, blood constituent and cardiovascular system can be damaged, cause gastrointestinal disturbance, induce immune system, internal system and
Disease of hematopoietic system, cause metabolic deficiency.A variety of VOCs can act on human body simultaneously in air, produce cumulative effect, and it endangers
Degree greatly increases.
Traditional VOCs control technologies are basically divided into two major classes：Recovery technology and destruction technology.Recovery technology is basis
The properties of VOCs in itself, by physical method, under certain temperature and pressure, use absorption and sorption agent and selectively penetrating
Film etc. realizes VOCs separation, mainly including absorption process, absorption method, condensation method and membrane separation process.And it is then to use to destroy technology
Chemistry or biological method, make VOCs gas molecules be changed into the water and carbon dioxide of small molecule, mainly include combustion method and biology
Method.
（1）Absorption process：The method of absorption process purifying VOCs is to utilize stripping liquid processing mixed gas, in mixed gas
One or more of gas components be dissolved in liquid, or with absorbing liquid component occur selection chemical reaction, remove it
The process of middle one or more of gases, so as to reach a kind of method of control atmosphere pollution.The method is suitable for atm number, medium
The processing of the waste gas containing VOCs of concentration.
（3）Absorption method：Absorption method is to utilize gaseous mixture of the porous solid sorbent treatment containing VOCs, utilizes solid
The unbalanced chemical bond force or molecular attraction on surface, make one or more components therein concentrate on the surface of solids, with up to
To the purpose of separation.The active charcoal of conventional adsorbent, NACF, activated alumina, molecular sieve and zeolite etc..
（3）Combustion method：VOCs is converted into carbon dioxide, water and hydrogen chloride etc. is nontoxic or small toxicity by combustion method
Inorganic matter process, the method for purification of referred to as burning, its chemical action be mainly under combustion oxidation and high temperature thermal decomposition effect.This
Method is applied to administer pernicious gas that is flammable or can decomposing in the case of a high temperature.The advantages of combustion method be clearance compared with
Height, typically more than 95%；Shortcoming is that direct combustion method is easily exploded, and wastes heat energy and is also easy to produce secondary pollution, heating power combustion
Burning method operating cost is higher.
（4）Condensation method：Condensation method is that have different saturated vapor pressures under different temperature and pressures using VOCs, is led to
Reduction temperature and increase pressure are crossed, condenses out the pollutant in steam condition, it is purified and is reclaimed.This method
Advantage is that apparatus and process is simple, and energy consumption is low, recyclable useful component；Shortcoming is the organic gas for being not suitable for handling low concentration, right
Entrance VOCs requirements are strict, and when chilling temperature is relatively low, power consumption is larger.
（5）Bioanalysis：Bioanalysis is under suitable environmental condition, using the vital movement of microorganism by VOCs gases
Harmful substance be transformed into simple inorganic matter（CO2、H2O）And the process of cellular material etc..Common Biochemical method VOCS's
Method has：Zinc cation method, biofiltration process and biological island.The advantages of bioanalysis is that clearance is high, small investment, equipment letter
Single, operating cost is low, less formation secondary pollution, has a wide range of application；Shortcoming is that microorganism is higher to environmental requirement, crushing compared with
Greatly, capacity of resisting impact load is poor, and equipment volume is big, is not suitable for the removal of high halogen compounds.
（6）Membrane separation process：Membrane separation process is utilized under the promotion of pressure differential, and the speed of air penetrating film is different, so as to
The process that admixture of gas is separated.The advantages of membrane separation process is that selectivity is good, and strong adaptability, energy consumption is low, no phase-state change, can
Reclaim useful component；Shortcoming is that investment is big, strong to the dependence of film；Higher is required to the granule surface contral of film, membrane separation device behaviour
It is required height.
At present, the organic waste gas treatment method used both at home and abroad includes absorption and sorption, condensation, burning and biotechnology etc.
Methods described above, but the shortcomings of investment is big, the cycle is long, operating cost is high all be present in it, and treatment effect is also difficult to meet
Increasingly strict emission request.For this reason, it may be necessary to new method and approach are found to solve this problem.
