Embodiment Construction

[0027] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, characteristics and effects of the ship cooling seawater desalination system and method of the present invention.

[0028]

[0029] figure 1 It is a schematic structural diagram of a ship cooling seawater desalination system in an embodiment of the present invention.

[0030] Such as figure 1 As shown, in this embodiment, the ship cooling seawater desalination system 100 is installed on the ship and is connected with the ship's cooling system and the compressed air generator respectively, and is used for cooling the discharged heat from the cooling system after exchanging heat. Seawater is desalinated to obtain fresh water that can be directly consumed. The ship cooling seawater desalination system 100 includes a seawater introduction part 10 , a filter part 20 , a heater ...

Abstract

The invention provides a ship cooling seawater desalination system and method. The system comprises a filtering part, a heater, a pressurizing conveying part, a distillation separator, a condenser and a vacuumizer, the filtering part is connected with a cooling water outlet of a cooling system and used for conducting filtering pretreatment on cooling seawater obtained after heat exchange to obtain filtered cooling seawater, the heater heats the filtered cooling seawater to obtain seawater to be desalinated, the pressurizing conveying part pressurizes the seawater to be desalinated and conveys the seawater according to a preset seawater flow, the distillation separator performs vacuum distillation separation treatment on the pressurized seawater to be desalinated to obtain concentrated seawater and water vapor, the condenser performs vacuum condensation treatment on the water vapor to obtain fresh water, and the vacuumizer is used for vacuumizing a steam cavity and a steam condensation cavity.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and in particular relates to a ship cooling seawater desalination system and method. Background technique [0002] Ships are important equipment for maritime defense forces. The energy consumption of their power devices is huge, but the contradiction between the extension of self-sustaining power and the limited fuel capacity is becoming increasingly prominent. It is imminent to recycle ship waste heat and improve fuel utilization. The heat balance analysis of a large number of diesel engines shows that the effective use of heat energy by marine diesel engines accounts for only 45-50%, and the energy lost by hot water is more than 20%. Cooling water waste heat has a high temperature and high recovery value, while other waste heat such as the heat dissipation of diesel engine body, air cooler and other equipment has low energy grade and is difficult to recover. Therefore, efficient...
