摘要： Provided is an extracting and separating device which includes: an ash reactor 12 for preparing a solution having a temperature of about 60° C. by using incineration ash containing sodium, potassium, and chlorine; a cooling crystallizer 16 for reducing the temperature of the solution to 30° C. to produce and separate potassium chloride; an absorption tower 11 for reacting the solution with carbon dioxide-containing gas to produce and separate sodium hydrogen carbonate; and a circulation path 13 for returning to the ash reactor 12 a liquid obtained after the production and separation of the potassium chloride in the cooling crystallizer 16 and the sodium hydrogen carbonate in the absorption tower 11.
