VOCs Removal Using the Photocatalyst

원문정보

초록

영어

To test the removal efficiency of the volatile organic compounds(VOCs), the photocatalyst in a removal apparatus of the VOCs is activated with the wireless pole ultraviolet ray lamp being an enough frequency. As the VOCs of xylene, toluene and methyl ethyl ketone (MEK) are inputted respectively into an influx hole of the batch experimental system, a regular consistency is made up 40, 80 or 500 ppm after mixing completely with the pan and motor which attaches on the ceiling in it. And after operating a removal apparatus of VOCs in it, the VOCs consistency is decreased. As the performance test, following results are obtained from this experiment. It takes 75 minutes to control until 5 ppm from the initial 80 ppm xylene consistency and the control efficiency specially appears with 60% to 45 minutes with operating the VOCs removal apparatus. It takes 50 minutes to control until 8 ppm from the initial 40 ppm toluene consistency and takes 70 minutes to almost perfectly treat with operating it. In MEK with the initial 500 ppm consistency, it takes 120 minutes to almost perfectly treat and the removal efficiency shows 80% after 90 minutes with operating it.
