PURPOSE : An energy source reusing method of a separation device for depositing an acidic gas is provided to minimize an outside influence of a stripper and ultimately reducing an amount of steam use of a re-boiler by maintaining a temperature in the stripper by inflowing a used steam between an outside and an inside of the stripper.CONSTITUTION : A separation device for depositing an acidic gas includes an adsorptive tower(110), a stripper(120), a re-boiler(130), and a heat exchanger(140). The adsorptive tower adsorbs an acidic gas contained in an exhaust gas to an absorbent and produces an adsorbent saturated with the acidic gas. The stripper separates the adsorbent saturated with the acidic gas to the acidic gas and the absorbent. The re-boiler maintains an inner temperature of the stripper by using an outside steam. The heat exchanger exchanges heat from the steam ejected from the re-boiler to the stripper. The acidic gas comprises at least one selected from the group consisting of carbon dioxide, hydrogen sulfide, sulfur dioxide, nitrogen dioxide, and carbonyl sulfide.COPYRIGHT KIPO 2013
