| Abstract: | The flowchart of the intermittent fixed be active carbon adsorption for purification of the organic waste gas was selected in accordance with the organic waste gas pollution problems from the wire printed district of the printed circuit board plant.Through the calculation ability of the causing cold and quantitites of the adsorption.some parameters of the activated carbon adsorption are designed, such as the gas velocity of the empty tower was about 0.6 m/s,the activated carbon is coconut.The activated carbon adsorption bed was designed as double story with drawers.After the adsorption bed purification,practical monitor testified: the efficient of the benzene.toluene and xylene purified to 81.59%, 83.50%, 85.43% by adsorption.The waste activated carbon was accumulated and desorption.The recycle organic products were mixed into the diesel oil to be used as fuel of motors. |
