Abstract

The invention relates to the technical field of marine energy-saving equipment, and particularly discloses a marine ammonia fuel reliquefaction heat energy-saving recovery system which comprises a recovery tank, a first sealing plate and a second sealing plate are fixedly connected to the inner surface of the recovery tank, the first sealing plate is located on the upper side of the second sealing plate, and an evaporation assembly is arranged on the outer side of the first sealing plate. The evaporation assembly comprises a water uniformizing base fixedly connected with the outer surface of the first sealing plate and an evaporation pipe fixedly connected with the outer surface of the lower end of the water uniformizing base, and the lower end of the evaporation pipe penetrates to the outer side of the second sealing plate. By arranging the evaporation assembly and the multiple sets of evaporation pipes, the contact area with an ammonia solution can be effectively increased, the heated evaporation efficiency of the ammonia solution can be effectively improved, then the ammonia gas precipitation speed can be effectively increased, meanwhile, ship waste heat is used for heating the evaporation pipes, and the utilization efficiency of heat energy can be effectively improved; and the loss of external energy can be further reduced.
