<p>PURPOSE:To efficiently separate and remove fine powder having prescribed particle size or below which is incorporated in activated carbon used as the adsorbing material by equally forming a plurality of opening parts which have an opening rate of specified value in a screening net and providing the screening net between a suction port and an exhaust port of the inside of a main body. CONSTITUTION:A suction port 5 is formed in the lower part of an equipment main body 11 whose inside is hollow and air is introduced into the inside through the suction port. Moreover an exhaust port 6 is formed in the upper part to pass the air introduced from the suction port 5 through the inside of the equipment main body 11 and to exhaust the air. A screening net 2 is arranged between the suction port 5 and the exhaust port 6 of the inside of the equipment main body 11. A plurality of long holes 2a are equally formed in the screening net 2 and an opening rate is regulated to 10-30% as a whole. On the other hand, a feed port 7 and a discharge port 8 are formed in the parts of the equipment main body 11 corresponding to the end parts of the screening net 2. Activated carbon is fed through the feed port 7. Activated carbon from which minute particles are separated and removed is discharged through the discharge port 8. Thereby fine powder having prescribed particles size or below is discharged together with high-speed air through the discharge port 8 and efficiently separated and removed.</p> |
