Description
Technical field:
The invention belongs to environmental protection technical field, be specifically related to the produced gas with foreign flavor of emulsion waste gas during cold rolling
Carry out the apparatus and method purified.
Background technology
In cold-rolling process, need to apply emulsion, and emulsion can be formed when high temperature strip steel surface evaporation and part cracking
Gas with foreign flavor, causes and has abnormal flavour in ambient air.This gas with foreign flavor complicated component, mass concentration is the highest, mainly with molecular weight
Relatively large hydro carbons and the aldehydes of semi-oxidation state, ketone and alkoxide are main.
The fog discharge system that general cold rolling industry milling train is arranged there is oil mist filter, but does not remove the equipment of gas with foreign flavor, although
Within 2015, country implements " steel rolling industrial atmosphere pollutant emission standard (GB 28,665 2012) ", only defines rolling unit
The emission limit of mist of oil, and the discharge to the gas with foreign flavor in air does not limit, but mill area and the emulsifying of floss hole periphery
Liquid gas with foreign flavor is objective reality.
Traditional gas with foreign flavor suppression technology has Physical, chemical method and bioanalysis.Wherein, physical method mainly include masking method,
Absorption method.Masking method is typically to admix with abnormal flavour foul smell with abnormal flavour with more intensive aromatic odor or other pleasant abnormal smells from the patient,
To shelter abnormal flavour or to change the character of abnormal flavour, make abnormal smells from the patient become able to as people and accepted, or use one can to offset or neutralize
The additive of stench, to alleviate abnormal flavour, the effect of masking method is different and variant because of each one impression degree.Absorption method is the most suitable
Process low concentration, the smell substance that pollutional load is the highest, the device initial stage of putting into operation eliminates the unusual smell effective, but along with the time of use
The growth effect that eliminates the unusual smell substantially weaken, and it is relatively costly and there is secondary pollution to change adsorbent.Chemical method is mainly wrapped
Including chemical washing method, oxidizing process, burning method, it is high, applied widely that the method has efficiency, but equipment investment, operating cost
Higher, it is suitable for the occasion that some concentration are of a relatively high.Biological method mainly includes Biological fitler method, biosorption process, soil
Composting process and biological deodorant etc., have the advantages such as simple, the less secondary pollution of technique, but the method exist screening and cultivates bacterium
Plant difficulty, take effect slowly, the defects such as biofilter floor space is big.These traditional smell pollutions control technology and are respectively arranged with its advantage drawn game
Limit.
Have developed plasma purifying method and photocatalytic oxidation in recent years, broadly fall into normal temperature oxidation method.Plasma is clean
Change technology system utilizes isoionic activity, and its ultimate principle is: put by the high-voltage pulse corona of steep-front, nanoscale narrow spaces
The modes such as electricity, obtain nonequilibrium plasma at normal temperatures and pressures, i.e. produce substantial amounts of high energy electron and O free radical, and OH is certainly
By base isoreactivity particle, smell pollution thing is aoxidized the structure destroying malodor molecule, thus reaches to eliminate the purpose of abnormal flavour.
Photochemical catalytic oxidation system, by luminous energy and the common effect of semiconductor catalyst, forms oxidation-reduction potential, produces OH free radical etc.
Active group, reacts with smell substance.Both approaches has certain effect for the gas with foreign flavor that molecular structure is fairly simple
Really, and operational management is convenient, but because being normal temperature oxidation, it is therefore desirable to the longer response time can be only achieved the effect of setting.
Therefore the time of staying inadequate or uneven time may produce incomplete oxidation product, the often association of the most this kind of device is the denseest
The ozone of degree, if do not taked appropriate gas removal ozone measure also can form secondary pollution.
In order to solve these problems, people take many corrective measures, including the method in various patents.In Chinese patent Shen
Please number 201210279387.X, " a kind of energy-efficient abnormal flavour exhaust gas purification and treatment device ", by single for the oxidation of pre-filtering activated carbon catalysis
The equipment that unit, energetic ion generator and ultraviolet light unit integrate, wherein, prefilter is using activated carbon as absorption
Medium, it is impossible to be used for oil-containing waste gas is processed, and the catalyst of catalytic oxidation unit is easily in dirty by the particulate matter in gas
Contaminating and lost efficacy, whole device structure is complicated, and investment is big.As can be seen here, current techniques equipment is not met by current industrial undertaking
In for the demand of stench purified treatment.
