Abstract

The invention relates to the technical field of marine diesel engines, in particular to a power generation and sea water desalination device based on marine diesel engine waste heat. The device comprises a waste heat power generation unit and a sea water desalination unit, wherein the waste heat power generation unit comprises an expander, an electric generator, a condenser, a working medium pump,a gas temperature adjuster and an evaporator; the sea water desalination unit comprises a multi-heat-source heat exchanger and a distilled sea water desalination device, a pressurized air pipeline ofa marine diesel engine is in pipeline connection with the second input end of the gas temperature adjuster, a smoke pipeline of the marine diesel engine is in pipeline connection with the second input end of the evaporator, sleeve barrel cooling water of the marine diesel engine is in pipeline connection with an evaporation coil pipe of the distilled sea water desalination device, three recyclingwaste heat sources of the marine diesel engine are sufficiently used, smoke waste heat and pressurized air waste heat of the marine diesel engine can be used at twice in a gradability manner, and thewaste heat use efficiency of the marine diesel engine can be improved.

Description

technical field [0001] The present application relates to the technical field of marine diesel engines, in particular to devices based on waste heat power generation and seawater desalination of marine diesel engines. Background technique [0002] Based on the current large-scale marine diesel engines, their marine diesel engines often only use less than half of the input energy. The energy not used by marine diesel engines includes: the energy of flue gas, the energy of pressurized air and the energy of jacket cooling water , so the remaining energy of the marine diesel engine is taken away by exhaust gas, jacket cooling water and pressurized air, which not only causes a huge waste of energy, but also causes thermal pollution to the environment. If the waste heat of these three parts can be recovered, not only can the utilization rate of fuel oil be improved, but also respond to the current green concept of energy saving and emission reduction. [0003] At present, there i...
