Description
Technical field
The present invention relates to environmental protection technical fields, are related to the processing method of organic exhaust gas more particularly to a kind of combined type
Volatile organic matter resource regeneration processing unit and method.
Background technology
Volatile organic compounds is the most common dirt of the industries such as petrochemical industry, pharmacy, printing, shoemaking, spray painting discharge
Contaminate object.As organic synthesis industry and the rapid development of petrochemical industry, the volatile organic compounds into air are more next
It is more.The processing method of organic exhaust gas has tens of kinds, and principle mainly has the recovery technology for recycling valuable solvent and decomposition to have
Two major class of destruction technology of machine exhaust gas.From the perspective of environmental protection and economy, solvent recovery technology more it is worth further research with
It promotes.
The type selecting of adsorbent is the key that solvent recovery technology, and suitable adsorbent need to be selected according to different exhaust gas constituents
Carry out solvent recovery.Activated carbon is a kind of agraphitic carbon with irregular microstructure, due to its larger specific surface area and
Stronger adsorption capacity, is the adsorbent of usage amount maximum, but activated carbon is affected etc. by aqueous vapor there are flammable, absorption property and lacked
Point limits its application.Large pore macromolecular resin also has organic exhaust gas excellent as a kind of very excellent adsorbent
Characterization of adsorption.Organic exhaust gas is relatively low in the heat of adsorption of resin surface, and adsorption process heating is smaller, and belongs to be not easy fuel wood in itself
Material, therefore its safety coefficient greatly improves, and is one of most potential sorbing material of organic exhaust gas.Hydrophobic molecule sieve can be
Higher adsorptive selectivity is still maintained under very high relative humidity, it is very big to organic matter adsorbance to the adsorbance very little of water,
And the material is non-combustible, it can be applied widely with high temperature regeneration.
Traditional VOCs treatment pattern：In the setting of organic exhaust gas emission source, cleaning system, this method are directed on the spot
The pollution sources that disposal of pollutants load is larger, continuously discharges are highly effective.But also there are many enterprises, particularly middle-size and small-size enterprise at present
Industry, productive prospecting are：Production process interval, emission point are scattered；The characteristics of discharge gas is：Air quantity is larger, concentration is less high.
In this case, the investment of traditional treatment in situ pattern and operating cost are higher..
The content of the invention

In the present invention, there is inert gas in air accumulator, inert gas is there are two effect, when finished when vapor is desorbed,
Residual gas in exchange system, cycle purge dry the adsorbent in absorbing unit, second is that making adsorbent cooling cold after dry
But.Dehydrater is used to remove the moisture content in fixed gas and purge gas.Through on-line monitoring system qualified discharge after fixed gas purification,
Fixed gas clean unit is also that can move integrally, for further removing the micro organic exhaust gas in fixed gas；On-line monitoring
System shows that interlocking during saturation is switched to another fixed gas clean unit and continues with fixed gas by fixed gas clean unit
In micro organic exhaust gas, the fixed gas clean unit of adsorption saturation is moved to desorption unit and regenerated.The indifferent gas
Body recycles in regenerative system is concentrated, and dry purging temperature is 80~150 DEG C, and cooling purging temperature is 0~30 DEG C, purging
Time is the 10%~50% of entire regeneration period.What indifferent gas purging can smoulder to avoid generation adsorbent in the drying process
Phenomenon reduces security risk.
As being further improved for above-mentioned technical proposal：
It is described parallel connection absorbing unit in filling adsorption material be activated carbon, zeolite molecular sieve, absorption resin in one kind or
Several combinations.
