Description
Technical field
The present invention relates to environmental project waste gas pollution control and treatment field, it is related to a kind of purifier and method, more particularly to one kind changes
Property pitch foul waste gas controlling device and method.
Background technology
Modified pitch refer to add rubber, resin,High molecular polymer, the outer-penetrating agents such as levigate rubber powder or other fillers
（Modifying agent）, or take to measures such as pitch mild oxidation processing, so that the performance of pitch or asphalt is improved and is made
Asphalt binder.In the production process of various modified asphalt materials, pitch need to be heated, be conveyed and satisfaction is made respectively
The pitch class mixture of kind technological requirement is for producing and using.In this technical process, a large amount of bitumen flue gas will produce.In flue gas
Containing gas chromatography, including carbocyclic ring hydrocarbon, cyclic hydrocarbon derivative and other maladorous gases, have much to the harmful work of health of human body
With glance coal contains a variety of multiring aromatic hydrocarbon substances such as BaP, benzanthracene, carbazole ", and be carcinogenic and strong carcinogen mostly
Matter, grain size is mostly between 0.1~1.0 μm, minimum only 0.01 μm, maximum about 10.0 μm, especially with 3,4- BaPs
For a variety of carcinogens of representative.Its main path being detrimental to health is attached on 8 um floating dusts below, by exhaling
Road is inhaled by suction human body.Therefore, purification treatment is carried out to modified pitch foul waste gas, so that discharge is met atmospheric environmental standards, is
It is very necessary.
Currently, common foul waste gas processing method has absorption process, absorption method, bioanalysis, heat accumulating type oxidizing process, plasma
Cracking process, UV photodestruciton method, chemical oxidization method, plants essential oil encapsulation method etc..Absorption process is to handle exhaust gas using stripping liquid,
To recycle or remove out one or more mixtures in exhaust gas, the substance of high concentration, but its adsorption effect can be recycled
With selectivity, and the dosage of adsorbent is larger, and floor space is also larger, absorbent and the insufficient feature of exhaust gas contact,
Applicability is limited during use.Absorption method is the poisonous and harmful element absorbed using solid absorbent in exhaust gas, minimizing technology
Simply, significant effect, but its adsorbent capacity is limited, is suitable for the processing of low-concentration organic exhaust gas, and when use need to consider to adsorb
The regeneration issues of agent.Bioanalysis is using specific micropopulation come odorant pollutant of degrading, and low energy consumption, but the training of microorganism
The condition of supporting is relatively difficult.Heat accumulating type oxidizing process is that foul waste gas is preheating to certain temperature, then by stench by the way of burning
Substance decomposition, non-secondary pollution, but its investment and operating cost are relatively high.Plasma cracking method is discharged using high voltage electric field,
Removal rate is high, but is influenced by exhaust gas concentration etc., and dangerous high, there are security risks.UV photodestruciton methods use high energy UV photons
Organic molecule is cracked, but is influenced by waste gas humidity etc., removal effect is unstable.Chemical oxidization method is aoxidized using strong oxidizer
Odorant pollutant, it is easy control of reaction conditions, easy to operate, but that there are oxidants is expensive, selectivity is strong, oxidant with it is useless
The uneven problem of gas mixing, there is an urgent need to reliable processing units to be used in combination.Although plants essential oil encapsulation method is in a short time
Stench peculiar smell can be covered up, but malodor molecule cannot be removed, the control requirement of atmosphere pollution cannot be met.

（4）Gas after oxidative degradation is passed through absorption secure device, adsorbent adsorbs organic substance and the regeneration of adsorbent is handed over
For progress；
（5）It is arranged being passed through by the clean gas after absorption secure device outside wind turbine.
Preferably, above-mentioned steps（4）It is by step（3）Gas after oxidation, degradation is input in absorption secure device, is mixed
When odorant is more than gaseous oxidizer in conjunction gas, will extra odorant be fallen by adsorbent absorption；Gas in mixed gas
When state oxidant is more than odorant, gaseous oxidizer is adsorbed by adsorbent, since gaseous oxidizer has oxidation odorant
Ability, the gaseous oxidizer adsorbed will aoxidize the odorant that adsorbs early period, and adsorbent be regenerated, and solve absorption
The agent replacement cycle is frequent, replaces difficult problem.
The cleaning principle of modified pitch foul waste gas of the present invention is that gaseous oxidizer is passed through in oxidation reaction apparatus, they
It is the extremely strong active particle of oxidisability, can aoxidizes, the malodor molecule in degradation modification pitch exhaust gas, reaches odorless without secondary dirt
Contaminate the purpose of substance discharge.Not by the foul waste gas molecule of gaseous oxidizer oxygenolysis, the adsorbent in secure device is adsorbed
