Disclosed is a greenhouse gas emission reduction device for a ship, which comprises a seawater supply unit (110) for supplying seawater, an absorption liquid circulation supply unit (120) for supplying and circulating an absorption liquid for absorbing CO2, an absorption tower (130) for regenerating the absorption liquid, an absorption liquid regeneration unit (140) for regenerating the absorption liquid, and an in-ship storage unit (150) for storing the CO2 in the ship after mineralization and micronization, and which stores the CO2 in the ship after mineralization and micronization. The absorption tower (130) includes a CO2 removal unit (131) that cools the exhaust gas discharged from the ship engine by reacting the exhaust gas with seawater, and that collects CO2 by converting CO2 into an aqueous carbonate solution by reacting the cooled exhaust gas with an absorption liquid. An absorption liquid regeneration unit (140) regenerates an absorption liquid and generates a precipitate by reacting an aqueous carbonate solution with a divalent metal oxide or a divalent metal hydroxide, and an in-ship storage unit (150) separates, dries and particulates the precipitate and then stores the precipitate in the ship.

    本发明公开一种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)及船内存储部(150),以使CO2矿物化、微粒化后进行船内存储,其中,海水供应部(110)供应海水,吸收液循环供应部(120)提供吸收CO2的吸收液并使其循环,吸收塔(130)包括CO2去除部(131),CO2去除部(131)使从船舶引擎排出的废气与海水反应而进行冷却,使冷却的废气与吸收液反应,以将CO2转换为碳酸盐水溶液而捕集CO2,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,船内存储部(150)对沉淀物进行分离、干燥、微粒化后进行船内存储。
