Inventor: YAMASHITA YOSHITAKA
IPC: B01D53/50
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To provide an acidic waste gas removing method and its device capa ble of remarkably reducing the generation and resynthesis of dioxin by easily neutralizing and removing the harmful acidic waste gas discharged from a waste incinerator etc. by short time reaction. SOLUTION: The method and device for neutralizing and removing the acidic waste in a short time by subjecting a calcium raw material to catalytic reaction with the acidic waste gas at the temperature not less than decomposition temperature of the calcium raw material are used as a basic means. Concretely, generated acidic waste gas is neutralized and removed by blowing the calcium raw material from a blowing port 27 into a combustion chamber of the incinerator 20 raised to the temperature not less than decomposition temperature of the calcium raw material or into a waste gas fue 22. Moreover, the redecomposition of a calcium salt compound is prevented based on particle size and a removing device capable of removing the calcium salt compound formed after neutralization with the acidic gas from a flue.  Slaked lime or calcium carbonate is used as the calcium law material, and when the slaked lime is used, the catalytic reaction is applied for about <=4 min at >=600 deg.C, and when the calcium carbonate is used, the catalytic reaction is applied for about <=4 min at >=900 deg.C.
