Abstract
PURPOSE: To obtain the energy reductive shaft furnace dehumidifying and air sending method with high reliability by a method wherein methanol is sprayed into wet air prior to being sent to a shaft furnace to carry out dehumidification of said air and an aqueous methanol solution is subjected to concn. control by utilizing other low temp. waste heat to be recirculated and reused.
CONSTITUTION: An aqueous methanol solution is sprayed into wet air from which dust is removed by an air filter 1 from a nozzle 17 and moisture in air is dissolved in the aqueous methanol solution. The methanol treated air is separated into dry air and the aqueous methanol solution in an eliminator 2 and the aqueous methanol solution is sent to a fractionating tower 9 through a pump 7 and vaporized methanol is liquefied by cooling water 14 such as sea water or the like in a condenser 12 and discharged again to the nozzle 17. A part of the aqueous mathanol solution after separated in the eliminator 2 is mixed into liquefied methanol from the condenser 12 through a bypass valve 18 while the concn. thereof is controlled by a concn. indicating controller 19. On the other hand, after dry air 3 is emitted from a shaft furnace blower 4, sensible heat thereof is used as the heat source of the fractionating tower 9 in a reboiler 10 and supplied to a shaft furnace 16 from a hot air oven 15.
