The course of work of the present invention：
The operation principle of a kind of petroleum vapor recovery of the present invention and exhaust treatment system is：
The direct recovery system of 1 high-concentration oil vapor
The high-concentration oil vapor come out from oil tank, is sent into low-temperature circulating water condenser, the gasoline in gas by vavuum pump
After component is by condensation, direct liquefaction, substantial amounts of heat is taken away by circulating condensing water, and this process is by under most oil gas condensation
Come, the oil of liquid is reclaimed in oil return tank by oil pump.
2 low concentration gas charcoal absorptions/desorption system
By condensed low concentration gas, into the adsorption tanks of the first adsorption tanks/second, by active carbon adsorption wherein
VOC components, in the first adsorption tanks after activated carbon A adsorption saturations, activated carbon A activated carbon is desorbed by vacuum, taken off
Attached high-concentration organic waste gas out enters in condenser system, carries out petroleum vapor recovery.Adsorption tanks are switched to the second absorption simultaneously
Tank is adsorbed.
3 activated carbons regenerate completely
Activated carbon vacuum desorption to a certain extent after, then carry out vacuum desorption and can waste the substantial amounts of energy, now using blowing
Scavenging the mode of ventilation, activated carbon is thoroughly regenerated, the tail gas of regeneration does not enter condensation recovery by ceaselessly vacuum
System, but enter in another set of desorption system after absorption, acceptable gas emptying.
The recovery of 4 loading place low-concentration organic exhaust gas
For organic exhaust gas caused by loading place compared with tank farm, concentration is low, while air quantity is big, and directly carrying out recovery needs to consume
Take substantial amounts of energy, thus the mode for first taking cellular activated carbon to adsorb is adsorbed to organic VOC, organic exhaust gas enters the 3rd
In adsorption tanks, after adsorption saturation, then the 3rd adsorption tanks are desorbed by vacuum desorption again, while are switched to the 4th absorption
Tank is adsorbed.
The organic exhaust gas for being desorbed out from activated carbon enters in low-temperature circulating water-cooling system, after condensation, liquid component
Directly in recovery such as oil tank.
The low-temperature catalytic burning processing of 5 VOC waste gas
When being less than setting value by monitoring VOC concentration on-line, organic exhaust gas is switched to catalysis burning, directly burnt till
CO2And water, qualified discharge.
Catalytic combustion system is monitored by on-line monitoring, ensures the security of system.
Gas-chromatography operation principle：
Gas chromatographicanalyzer is to be used as mobile phase (carrier gas) using gas.By carrying after sample is admitted to injector and gasifies
Gas is carried along into packed column or capillary column.Due to the difference of the boiling point of each component, polarity and adsorption coefficient in sample, make each group
Part separated in post, then by being connected on physicochemical characteristics of the detector after post according to component, by each component in order
Detect.Finally by secondary meter (such as recorder, chromatographic data processor, chromatographic work station) by the gas phase color of each component
Spectrogram is recorded and analyzed so as to obtain the analysis report of each component.
Above-described embodiment is the description of the invention, is not limitation of the invention, it is any to simple transformation of the present invention after
Scheme belong to protection scope of the present invention.
