Description
Technical field
The invention belongs to waste gas treatment equipment technical field, is related to a kind of off-gas cleaning equipment, more particularly to a kind of removal
Stench degraded VOCs off-gas cleaning equipments.
Background technology
Impact of the foul gass to human environment is one very important problem of today's society, has caused people more next
More concerns.In some developed countries, the ratio that people complain to stench also more and more higher.In Australia, to stench
Complaint account for environmental pollution is always complained 91.3%；In the U.S., whole air pollutions are complained more than 50% is accounted for；In Japan for only
Inferior to the second of noise.In each big city of China, complaint of the resident to stench has been presented the trend of sharp increase, has caused
The great attention of GUAN spot door.
It is distributed in impact standard present many aspects of the foul gass in city country life cell to health：Give
People bring offending sensation, if things go on like this, can more cause physiology and psychological disease, such as emotional instability, agitation, food
It is intended to depressed, olfactory sensation imbalance, insomnia even nausea, headache and induces asthma etc..The stench of high concentration can more cause human body important
There are obstacle and pathological changes in physiological Mechanism, make one to produce chronic disease and shorten the life-span, and when serious even contaminated crowd can occur
Acute disease simultaneously causes death.
China takes at present purified treatment measure, such as Production by Catalytic Combustion Process, absorption process, absorption method etc. to organic exhaust gas, from
From the end of the eighties, environmental worker both domestic and external increasingly pays close attention to the handling process that gaseous contaminant is removed using bioanalysises, and
It is increasingly becoming one of forward position focus problem of world industry waste gas purification research.In Germany, Holland and Japan etc. in deodorize and near
Existing some successful examples in the organic waste-gas purification practice of several years, counted according to 1991, and there is more than 500 biofilter in Europe
In operation, most treatment effeciency is more than 90%.It is domestic to be still in terms of bioanalysises remove the research of gaseous contaminant
Starting stage, it is anticipated that biologic treating technique has broad prospect of application in Air Pollution Control field.
In recent years, the pollution control of VOC (abbreviation VOC) waste gas becomes the another of countries in the world concern
Focus；Volatile organic waste gas process refer to volatile hydrocarbon and their derivative, it include hydro carbons, aromatic hydrocarbons,
Alcohols, aldehydes, ketone, esters, amine, organic acid etc..It is near several that biologic treating technique is applied to the purified treatment of organic exhaust gas
Year is inchoate, is an emerging technology.Common biological treatment includes Biological fitler method, biological island, biology
Washing method, membrane bioreactor and rotating disc type biofiltration reactor method.
It is by the harmful substance in waste gas on the biological cleaning process nature of industrial waste gas using the vital movement of microorganism
It is changed into simple Organic substance (such as CO2 or H2O) and Cytoplasm.It is being proposed according to Dutch scholar Ot-tengraf, normal in the world
Absorption-biofilm theory, when biochemical process processes organic exhaust gas, typically experiences following step,
Organic pollution in 1 waste gas contacts first and is dissolved in the water (i.e. mountain mists membrane diffusion is to liquid film) with water
2 organic pollutions being dissolved in liquid film diffuse further into biomembrane under the promotion of concentration difference, and then by it
In microorganism-capturing and absorb
3 organic pollutions entered in microbial body are in the metabolic process of its own by as the energy and nutrient substance
It is decomposed, Jing biochemical reaction is eventually converted into harmless compound, such as CO2 and H2O.
In sum, the biological treatment of waste gas is that the gaseous contaminant in waste gas is decomposed using the life process of microorganism
Change into less or or even innocuous substance.There are various microorganisms in nature, it is nearly all inorganic and organically dirty
Dye thing can be converted.Biological treatment need not regenerate and other high-level processes, compared with other methods of purification, with equipment letter
The advantages of list, low, safe and reliable energy consumption, non-secondary pollution, but the polluter mankind can not be recycled scientific and technological constantly progressive
Promotion under be devoted to that, operating cost little to environmental disruption be low, easy to operate, efficiency high processing method exploration all the time.
Foreign countries' research of Biochemical method organic exhaust gas has more than 30 years history, and the technology is quite ripe.
The biological treatment of organic exhaust gas is most economical effective method, and effect is good, operating cost is less than any process
Method, it is safe, easy to operate.The biological clarification of VOC has direct microbial cleaning method, indirect microorganism treatment, and (first water absorbs
Biological wastewater treatment again) and plant purification method etc..Directly biological cleaning have bio-absorbable pond, zinc cation pond, bio-trickling filter,
Biological filter, high treating effect, easy to operate, wherein biological filter technology maturation, using more.As Germany and Holland build
There is hundreds of waste gas biofilter, operational effect is all fine.Indirectly biological treatment is to absorb VOC with water or weak lye, wherein
The materials such as the alcohols, the aldehydes that contain are soluble in water, the means of waste water reuse biodegradation after absorption, make discharged wastewater met the national standard.Plant is net
Change method is exactly that on-site increases green coverage, and the pollutant in air are absorbed and converted using green plantss come purify air, this
The method of kind is applied to the pollution of overall situation low concentration.
Conventional odor pollution control has absorption, activated carbon adsorption, burning, medicament sprinkling, plasma with degraded VOC technologies
Oxidation, biotechnology degraded etc., it is selected generally according to the type and characteristic of waste gas.
Processing equipment is mostly only with single kind for the treatment of technology present on existing market, therefore the suitability is not wide enough.And
Now industrial waste gas comparison of ingredients is complicated, and only for the product of single treatment object, its treatment effect can have a greatly reduced quality naturally.And
In actual applications, many equipment are due to not perfect enough in design, and using effect is also unsatisfactory.Generally there is treating capacity not
Greatly, handling rate is not high, high energy consumption, the problems such as equipment volume is big.
In view of this, nowadays in the urgent need to designing a kind of new waste gas purification apparatus, to overcome existing purifier to deposit
