To provide an apparatus and method for purifying a refuse-derived fuel gasification gas, which do not cause the decrease in desulfurization rate with regard to the refuse-derived fuel gasification gas containing a cyanogen compound and hydrogen sulfide; and to provide a processing apparatus and processing method which include processing cleaning water that has been used for the purification.
The apparatus for purifying the refuse-derived fuel gasification gas pyrolyzes and partially oxidizes the refuse to gasify it. The apparatus includes: a unit 21 for cooling and cleaning the gas by spraying acidic cleaning water into the gas and so on; a unit 23 for cleaning the resultant gas cooled and cleaned by the unit 21, by spraying alkaline cleaning water having pH of 7.5-8.2 into the gas and so on; and a desulfurization unit 25 for desulfurizing the resultant gas cleaned by the unit 23.
