Disclosed is a greenhouse gas emission reduction device for a ship, which is provided with a seawater supply unit (110), an absorption liquid circulation supply unit (120), an absorption tower (130), an absorption liquid regeneration unit (140), and an outboard discharge unit (150) so as to mineralize CO2 and discharge the mineralized CO2 to the outside of the ship, and to minimize the corrosion of seawater to a separator (152), the present invention relates to a ship engine (10) comprising a seawater supply unit (110) that supplies seawater, an absorption liquid circulation supply unit (120) that supplies and circulates an absorption liquid that absorbs CO2, and an absorption tower (130) comprising a CO2 removal unit (131) that cools off-gas discharged from the ship engine (10) by reacting the off-gas with seawater, and that converts CO2 into an aqueous carbonate solution by reacting the cooled off-gas with the absorption liquid, the present invention is provided with an absorption liquid regeneration unit (140) for regenerating an absorption liquid and generating a precipitate by reacting an aqueous carbonate solution with a divalent metal oxide or a divalent metal hydroxide, and an outboard discharge unit (150) for separating the precipitate and discharging the precipitate to the outside of the ship by means of seawater.

    本发明公开一种船舶的温室气体减排装置,所述船舶的温室气体减排装置包括海水供应部(110)、吸收液循环供应部(120)、吸收塔(130)、吸收液再生部(140)及船外排出部(150),以将CO2矿物化并向船外排出,并且使海水对分离器(152)的腐蚀最小化,其中,所述海水供应部(110)供应海水,所述吸收液循环供应部(120)提供吸收CO2的吸收液并使其循环,所述吸收塔(130)包括CO2去除部(131),所述CO2去除部(131)通过使从船舶引擎(10)排出的废气与海水反应而进行冷却,并且使冷却的废气与吸收液反应,以将CO2转换为碳酸盐水溶液,从而捕集CO2,所述吸收液再生部(140)通过使碳酸盐水溶液与二价金属氧化物或二价金属氢氧化物反应而再生吸收液并生成沉淀物,所述船外排出部(150)分离沉淀物,并借由海水将沉淀物排出到船外。
