WASTE WATER TREATMENT APPARATUS FOR USE IN TWIN TOWER GASIFICATION FACILITY AND TWIN TOWER GASIFICATION FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a waste water treatment apparatus of a simple structure for use in a twin tower gasification facility, capable of preventing the deterioration of efficiency while reducing the cost thereof without discharging waste water to outside, and a twin tower gasification facility.;SOLUTION: The twin tower gasification facility comprises a gasification furnace 1 that gasifies a raw material charged into a fluidized bed of a fluid medium to produce a gasified gas and a combustible solid component, a combustion furnace 2 that burns the combustible solid component produced in the gasification furnace 1 and introduced from the gasification furnace 1 thereinto together with the fluid medium, a fluid-medium separation device 3 that separates the fluid medium from the flue gas introduced from the combustion furnace 2 and returns the separated fluid medium to the gasification furnace 1, a gasified gas purification device 4 that purifies the gasified gas produced in the gasification furnace 1, a concentrator 5 that heats the waste water discharged from the gasified gas purification device 4 with steam to concentrate the same, and a pump 6 that sends waste water concentrated in the concentrator 5 to the combustion furnace 2.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
