Abstract

PURPOSE: To reduce power consumption for the pump, which is used for circulating cooling water, by rotating a water wheel with the dynamic press. of cooling water having been used in a tower for dehumidifying high press. air, which is blown into a shaft kiln, and by circulating the cooling water from a cooling tower to the dehumidifying tower by use of the turning force of the water wheel.
CONSTITUTION: Air for a shaft furnace, after pressurized by a blower 1, enters into a dehumidifying tower 4, where it is cooled and dehumidified and is blown into the shaft furnace. In the dehumidifying tower 4, the pressurized air is cooled and dehumidified at a preceding and a following heat exchangers 8A, 8B with shower of cooling water flowed in through cooling water supply pipes 9, 10. The high press. air, liberated in a demister 15 from waterdrops formed in cooling and waterdrops of the cooling water, heated in heat-recovery tank 35 with pressurized air before it enters into the dehumidifier 4, enters into the shaft furnace. When the preceding cooling water 28 flows into a cooling tower 16 through a discharge line 27, it drives a water wheel 38 with its dynamic press. and helps a motor 37 which drives, against the press. of pressurized air in the dehumidifier, a pump 24 for spraying cooling water shower through a cooling water supply line 9. Hereby, the motor 37 is made compact.
