The precursor of Pm2.5, with the frequent generation of current haze hazard weather, scarcity of resources, economic competition increasingly fierce, volatility
Organic Waste Gas Pollution is administered and the clean manufacturing enforcement of relevant industries is imperative.
Process to volatile organic waste gas is generally using many micropore materials such as activated carbon, molecular sieve, NACFs at present
Material carries out adsorption treatment, then by high-temperature vapour to adsorption saturation after microporous materials carry out organic solvent desorption, and using cold
But water is condensed with the mixture of steam to the organic matter being desorbed, so as to reclaim organic solvent.But the technique was adsorbed
Journey needs to fill the adsorbing mediums such as big carbon content active, will consume water vapour and cooling water during desorption in a large number, and substantial amounts of heat
Slattern in condensation process, while after solvent is separated with water, can also produce substantial amounts of waste water, substantial amounts of adsorbing medium inactivation
After need to change, need further to process, whole complex technical process, process unit investment is big, is also easy to produce secondary pollution, and
Energy waste, operation energy consumption are high.Simultaneously as atmospheric environment is increasingly serious, the high pollution that boiler is produced equally makes country right
Strict management and control is carried out in boiler construction, substantial amounts of vapor demand also becomes existing purification of volatile organic waste gas technical matters and pushes away
A wide restriction.
