REMOVAL OF DIOXIN AND REMOVING DEVICE OF DIOXIN

摘要

PROBLEM TO BE SOLVED: To enable removal of dioxins in a rather simple structure by introducing a combustion waste gas into a contact cylinder through its lower part and passing the gas upward while blowing upward an activated carbon of a specified particle size and a surface area in the contact cylinder to adsorb and remove the dioxins in the waste gas with the activated carbon. ;SOLUTION: After a waste gas produced in an incineration furnace 1 is introduced into a gas cooling device 5 and cooled to a specified temp., the gas is introduced into the lower part of an activated carbon contact cylinder 7. The gas is made to flow through plural air permeating holes of a container 25 to the inside of the container 25. An activated carbon is supplied from an activated carbon supply part 11 to the inside of the container 25. The supplied activated carbon is blown up by the gas and efficiently in contact with the waste gas to adsorb and remove the dioxins in the gas. Then the waste gas from which the dioxins is removed, and the activated carbon adsorbed the dioxins are introduced into a cyclone device 17 where the waste gas is centrifugally separated from the activated carbon. The activated carbon is collected in a dust box 19 and then reused.;COPYRIGHT: (C)1999,JPO
