APPARATUS FOR GASIFICATION OF WASTE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for the gasification of waste that can remove impurities such as moisture, tar and the like contained in a gas produced in a gasification furnace without requiring a large-scale device for drainage treatment.

SOLUTION: The apparatus for the gasification of waste is provided with a fluidized-bed gasification furnace for pyrolyzing waste; a second cooling tower 9 for sprinkling cooling water on a product gas produced in the gasification furnace to condense impurities such as water, tar and the like contained in the product gas; a condensate tank 35 into which a condensate 33 condensed through the second cooling tower 9 is fed; a cooling water circulating passage 47 equipped with a pump 45 for circulating the condensate 33 from the condensate tank 35 and supplying the same to a sprinkling nozzle 31 of the second cooling tower 9; and a purification tower 51 for a circulating cooling water which is equipped in the cooling water circulating passage 47 and is filled with an adsorption material 49 for adsorbing impurities contained in the circulating cooling water.
