Description
Technical field
The present invention relates to environmental protection application field, relates generally to a kind of adsorption type low temperature plasma advanced treating stench
The system and method for gas, processing system and method are handled more particularly to the deep purifying to foul gas.
Background technology
The processes such as industrial production, sewage disposal and garbage loading embeading can produce odorant, and these pollutants spill into air
In pollute the environment, be detrimental to health, and regional effect is brought everywhere as the flowing of air is spilt into, therefore arranging
Need to take appropriate technological means to be handled before putting.Wherein endanger larger odorant have inorganic and organic sulfur compound,
Ammonia and organic amine, aromatic hydrocarbons etc..
What on January 15th, 1994 implemented《Emission standard for odor pollutants》（GB14554-93）Define odorant pollutant
（Odor pollutants）Referring to all stimulates olfactory organ to cause people unhappy and damages the gaseous matter of living environment.It is smelly
Gas concentration（Odor concentration）Refer to foul gas（Including peculiar smell）It is diluted, is diluted to just with odorless air
When odorless, required dilution is counted, so without guiding principle amount.For a certain material《Standard》Define methyl mercaptan, methyl sulfide and benzene
The concentration of emission of the organic matters such as ethene, but《Emission standard for odor pollutants》（GB14554-93）With《Air Pollutant Emission mark
It is accurate》（GB16297-96）Promulgate and have 20 years as long as, if industry continues according to this effluent standard, the surrounding air matter of various regions
It is increasingly strict that amount would become hard to satisfaction《Ambient air quality》（GB3095-2012）.Therefore the stench of different industries discharge
The discharge standard of different industries is should refer to, such as《Urban wastewater treatment firm pollutant emission standard》（GB18918-2002）、《Medical treatment
Mechanism water pollution discharge standard》（GB18466-2005）Deng all defining specific emission standard.With people to environmental protection and
The consciousness of health gradually steps up, and starts to administer the pollutant of the processing system of full-scale plant waste gas and waste water release gas,
To solve the phenomenon and problem that foul gas disturbs residents.
At present, domestic and international common processing foul gas device mainly has following several：Combustion method, oxidizing process, absorption process,
Absorption method, biological process and low temperature plasma method.Wherein, combustion oxidation method is degraded suitable for high concentration foul gas, is inhaled
Attached method is mainly used to handle the foul gas of low concentration.Absorption process purification gaseous contaminant is to remove gaseous contaminant to eliminate
Pollution, the method are applied to the foul gas of middle and high concentration.Absorption process and absorption method are not removed pollutant thoroughly, but
Foul gas is transferred in solid phase or liquid phase, and then reduces the bad smell of air.And bioanalysis is in processing low concentration, Yi Sheng
Effect consumption and more economy during the stench of thing degraded, requirement of the microorganism to living environment is more harsh, works as treatment conditions
When growth to microorganism has limited, the decrease with the obvious advantage of microorganism process.However, low temperature plasma method generally exists
Under normal temperature and pressure, the method can reach the effect of preferable degradation of contaminant.
Due to foul gas composition and the complexity of property, traditional monotechnics is generally unattainable processing in many cases
It is required that；Absorption and sorption method can not thoroughly remove odorant pollutant under normal circumstances；Combustion method, oxidizing process and biological process
There are many limitations, and it is economical unreasonable；And lower temperature plasma technology has simple technique, high treating effect and secondary pollution
The advantages that few, progressively show its advantage technically and economically, the particularly application in processing low content VOCs and stench
In.In recent years, because the superiority that lower temperature plasma technology processing foul gas has, many researchers have carried out correlation
Explore, using different types of plasma-generating source, design different reactors, and achieve certain achievement.At present, it is single
Solely the problems such as treatment effect is low, and accessory substance is difficult to control is still suffered from using a kind of technique device processing foul gas, and absorbent-type
Lower temperature plasma technology can effectively improve clearance, reduce energy consumption, reduce secondary pollution, be provided for the removal of foul gas
One new technological development direction.
