Micromolecular compound.Non-destructive method, i.e. absorption method, mainly carbon adsorption, absorption, condensation and membrane separation technique, by physics
Method, controls temperature, and pressure is enriched with permoselective membrane and selective absorbent etc. and separating volatile organic compound
Thing.Traditional volatility exhaust-gas treatment conventional absorption process, absorption method, condensation method, combustion method removal etc..Absorption process high energy consumption；Inhale
Receive agent consumption larger, need to be continuously replenished；The adsorbance of absorption method is little, and uncomfortable aqueous or containing shot-like particle waste gas；Single condensation
Method wants up to standard to be needed to drop to very low temperature, and power consumption is huge；Combustion method catalyst price is high, and requires to contain in waste gas
The composition that catalyst can be caused to inactivate.
Content of the invention
The purpose of this utility model provides a kind of volatility organic tail gas processing meanss, and system processing power is big, processes effect
Rate is high, and continuously can work.
For solving above-mentioned technical problem, the technical scheme adopted by this utility model is：At a kind of volatility organic tail gas
Reason device, including be sequentially connected adsorption tanks, vacuum pump, First Heat Exchanger, the first gas-liquid separator, the second heat exchanger and second
Gas-liquid separator；The First Heat Exchanger and the second heat exchanger are respectively connected with refrigeration compressor set, first gas-liquid separator
Liquid outlet connection gun barrel with the second gas-liquid separator.
The adsorption tanks are two, and are arranged in parallel, and adsorption tanks are also associated with the blower fan for introducing organic tail gas.
The gas outlet of second gas-liquid separator and gun barrel is connected to the air inlet of blower fan.
The condensation temperature of first gas-liquid separator is -35 ~ -40 DEG C, and the condensation temperature of the second heat exchanger is -65 ~ 75
℃.
This utility model also includes a kind of volatility organic tail gas processing method, comprises the following steps：
Organic tail gas are introduced in adsorption tanks and are adsorbed, adsorption temp≤65 DEG C, time are 15-30min, then carried out
Vacuum desorption, pressure are 100-200Pa, and the composition after desorption carries out heat exchange condensation to -35 ~ -40 DEG C, carries out gas-liquid separation, then
Condensed liquid is collected in gun barrel, gas is further exchanged heat condensation to -65 ~ 75 DEG C, finally carries out gas-liquid
Separate, condensed liquid enters gun barrel and collects, gas returns to adsorption tanks and continued with.
Adsorbent in described adsorption tanks is active carbon from coal.
The absorbed portion arranges two adsorption tanks, and one for, when adsorbing, another is used for regenerating, and two make in turn
With.
This utility model is adsorbed initially with activated carbon, is enriched with Organic substance tail gas adsorption using its strong power that catches,
Significantly reduce organic concentration in tail gas.And the organic gas being desorbed after working as activated carbon adsorption saturation are condensed back
Receive, it is ensured that the regeneration of activated carbon and service life.
The device disposal ability is big, and treatment effeciency is high, and continuously can work.
This utility model advance is the process to low concentration atm number tail gas, due to tail gas concentration low large-minded, first
Adsorption and enrichment is carried out with activated carbon, has adsorbed the air that organic compounds have been vented in tail gas, after isoreactivity charcoal adsorption saturation again
Which is desorbed, the gas concentration height being desorbed out is narrow-minded, now the high-concentration oil vapor again to desorption out is condensed
Process, process energy consumption and substantially reduce, it is to avoid to the high energy consumption needed for large quantity of air condensation in tail gas, saved operating cost.
