Smoke Clearing Method using Activated Carbon and Natural Zeolite

Yuliusman Yuliusman, Widodo Wahyu Purwanto, Yulianto Sulistyo Nugroho



The purpose of this research is to study
the effectiveness of smoke clearing with adsorbents measured in situ using the photoelectric type smoke detection system. The
influence of the type, size and the mass of the adsorbents was evaluated
against the smoke clearing process. Adsorbent types studied were commercial activated carbon, ZnCl2-activated carbon, and activated natural
zeolite, with the size of 0.6-1.0 μm,
1.0 to 2.0 μm, 53-106 μm, and
106-212 μm, and the mass of 1, 3, and 5g. The smoke was generated
by burning tissue paper using an electrical soldering apparatus. The adsorbent was dispersed using a pressurized nitrogen system. The results
showed that in comparison with no adsorbent, the activated carbon and natural
zeolite were more effective for clearing the
smoke. The order of clearing
effectiveness was
best achieved by commercial activated carbon, ZnCl2-activated carbon and activated natural
zeolite, respectively. Particle size of 53 micron provided the most effective performance. The more
mass of adsorbent dispersed, the faster the clearing process. Clearing process at the top
of the column was faster than that at the bottom. The best t10 value obtained for the top, middle and
bottom column were
4, 4.6, and 7.7 minutes, respectively. In addition, the average adsorption of carbon monoxide
was less than 15%.
