The invention relates to the technical field of ship construction, and particularly discloses a waste heat recovery system and a ship. The waste heat recovery system comprises an air cooler, a circulating pump and a fresh water generator; the air cooler is provided with a first inlet and a circulation port; the water inlet end of the circulating pump can communicates with a fresh water cooling system, and the water outlet end of the circulating pump communicates with the first inlet, so that cooling water in the fresh water cooling system enters the air cooler through the circulating pump; and one end of the fresh water generator communicates with the circulation port, and the other end of the fresh water generator communicates with the water inlet end of the circulating pump. The ship adopts the waste heat recovery system, the cooling water in the air cooler enters the fresh water generator in a circulating mode through the circulating pump, waste heat of the cooling water provides energy for fresh water generator desalination, and the fresh water generator desalination capacity of the ship is improved. Meanwhile, waste heat of the cooling water is fully utilized, and energy consumption is reduced.
Description
technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a waste heat recovery system and a ship. Background technique [0002] At present, the propulsion system of ships is mostly driven by fuel oil and methanol dual fuel. When using fuel-driven mode, the ship needs to consume a large amount of fresh water. [0003] In order to save the fresh water resources of ships and ensure the fresh water supply of ships, water generators are generally used for desalination of seawater, and the water generators are used to desalinate to ensure the propulsion water of ships. At present, the jacket water of the main engine of the ship is generally used to provide the heat source for the water generator. As the water consumption of the propulsion system increases, the desalination capacity of an existing water generator can no longer meet the navigation needs of ships. It is necessary to add another water generator to increase th...
