Abstract

The invention relates to an LNG ship heat energy comprehensive utilization system, which comprises an LNG engine, a closed circulating heat exchanger, a waste gas heat exchanger, a tube bundle type heat exchanger, a CNG cylinder, an LNG steam cylinder, a heat dissipation coil pipe, a low-temperature cooling water tank, an evaporative fresh water making machine and a sea water pump, wherein the LNGengine provides heat energy for the whole system, and the LNG steam cylinder, the tube bundle heat exchanger and the CNG cylinder form a constant-pressure self-conversion module; a cabin temperatureconstant-temperature module is formed by the heat dissipation coil and used for maintaining the cabin temperature constant; the waste gas heat exchanger, the evaporative fresh water making machine andthe sea water pump form a fresh water making module; the closed circulating heat exchanger and the sea water pump form a closed circulating cooling module, and the low-temperature cooling water tankforms an open circulating cooling module which is used for guaranteeing good cooling of the LNG engine. In the invention, the heat energy generated by working of the LNG engine and cold energy generated by converting LNG into CNG are utilized, and the functions of self-pressurization and self-conversion of the system, constant cabin temperature, cooling of the engine and efficient desalination areachieved by reasonably controlling the flow of high-temperature cooling water and low-temperature cooling water.

Description

technical field [0001] The invention relates to the technical field of thermal energy utilization, in particular to a thermal energy comprehensive utilization system of an LNG ship. Background technique [0002] As we all know, ships powered by fossil energy will cause serious pollution emissions, so the development of green ships is imminent, and the application of clean energy power systems is the best solution. [0003] As a clean energy source, liquefied natural gas (LNG) releases a large amount of cold energy when it is vaporized. When it is burned as a fuel, it basically does not produce polluting gases. However, in existing LNG ships, this part of cold energy is often not effectively utilized. Utilization of low-grade thermal energy and cold energy of LNG can not only improve energy utilization efficiency, but also realize efficient development and utilization of new energy. This patent takes this as a starting point and invents a set of perfect LNG ship thermal ene...
