MANUFACTURING METHOD FOR NEUTRALIZER USING BOTTOM ASH OF FLOATING BED COAL FIRED POWER PLANT

摘要

The present invention includes (a) a first step of inputting the bottom ash recovered from the boiler of a fluidized bed coal-fired power plant into a screen separator to select a raw material of light weight aggregate, heat medium, or reduced iron over a set size included in the bottom ash; (b) a second step of filtering foreign matter of metallic material contained in the fine-grained bottom ash less than the set size provided in the first step; (c) The third in which the fine floor ash provided in the second step is supplied to the air rotary separator to separate the fine floor ash into the heavy light floor and the light light floor according to the difference in specific gravity, so that a hard light floor ash containing an alkaline neutralizing agent is obtained. Including a step, the step (c), the storage case installed on the base frame, the bottom ash is accommodated; A supply driver for providing power to discharge the bottom ash stored in the storage case in a predetermined amount; A high-speed rotating unit for separating the granulated component and the fine-grained component by a difference in specific gravity of the compositions contained in the bottom ash while rotating the bottom ash discharged from the storage case; A first collection container in which the assembled components discharged from the high-speed rotation unit are collected; And a second collection container in which particulate components discharged from the high-speed rotation unit are collected.
