Disclosed is a greenhouse gas emission reduction device for a ship, comprising: a seawater supply unit (110) for supplying seawater; an ammonia water production unit (120) that produces and supplies ammonia water by reacting the clean water with NH3; an absorption tower (130) in which is formed a CO2 removal unit (133) for reacting and cooling the exhaust gas discharged from the ship engine (10) with the seawater supplied from the seawater supply unit (110), reacting the cooled exhaust gas with the ammonia water from the ammonia water production unit (120), converting CO2 into NH4HCO3 (aq), and removing CO2; and an ammonia regeneration unit (140) for reacting NH4HCO3 (aq) discharged from the absorption tower (130) with Ca (OH) 2 or Mg (OH) 2, regenerating NH3 (g), and returning the regenerated NH3 (g) to the ammonia water production unit (120). The purpose of the present invention is to separate and discharge NOX, SOX, and CO2 from an exhaust gas so as to satisfy IMO greenhouse gas discharge control, removal of CO2 after removal of SOX, improvement of CO2 removal efficiency, and removal of side reactions caused by SOX remaining during NH3 regeneration, so that impurities are not included during ammonia recovery.

    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,所述海水供应部110供应海水;氨水制造部120,所述氨水制造部120使清水与NH3反应而制造并供应氨水;吸收塔130,所述吸收塔130形成有CO2去除部133,所述CO2去除部133使从船舶引擎10排出的废气与从海水供应部110供应的海水反应并冷却,使冷却的废气与来自氨水制造部120的氨水反应,将CO2转换成NH4HCO3(aq),去除CO2;及氨再生部140,所述氨再生部140使从吸收塔130排出的NH4HCO3(aq)与Ca(OH)2或Mg(OH)2反应,使NH3(g)再生并回归供应到氨水制造部120;从废气分离排出NOX、SOX、CO2,使得满足IMO温室气体排出管制,去除SOX后去除CO2,提高CO2去除效率性,去除因NH3再生时残存的SOX导致的副反应,使得在回收氨时不包含杂质。
