Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0014] Such as figure 1 As shown, a power generation system based on the waste heat of a marine diesel engine, the system includes a marine diesel engine 1, a boiler 2 for burning the exhaust gas of the marine diesel engine, and a drum 3, and the exhaust gas discharged from the marine diesel engine 1 is combusted and evaporated by the boiler 2 and then discharged. The drum 3 is connected to the preheater 5 through the pipeline and the circulating water pump 4, and the preheater 5 is connected to the hot well 7 through the pipeline through the feed water pump 6;

[0015] The water in the drum 3 is first heated and evaporated by the preheater 5 through the circulating water pump 4 to become a mixture of saturated steam and water (that is, unsatura...

Abstract

The invention discloses a power generation system based on marine diesel engine waste heat. According to the system, the water in a boiler tube is heated and evaporated through a circulating water pump via a preheater and is converted into mixture of vapor and water, and the vapor and the water are separated in the boiler; the separated saturated vapor enters the boiler tube and is guided by the same, a part of the vapor enters a hot well through a vapor heating device for vessel heating and living, and the residual majority of the vapor enters a turbine generator to work for power generation; the turbine generator is connected to a condenser connected to a condensing pump. The system has the advantages that fuel cost can be saved, air pollution can be reduced, fuel and water storage can be reduced, and the vessel cargo capacity is increased accordingly.

Description

technical field [0001] The invention relates to a power generation system, in particular to a power generation system based on waste heat of a marine diesel engine. Background technique [0002] Since the world's oil crisis in 1973, coupled with the aggravation of environmental pollution, the issue of energy conservation has attracted increasing attention. How to improve the utilization rate of energy, reduce the emission of marine diesel engine exhaust, and protect the environment on which human beings live are the subjects that many people are devoted to research. [0003] As far as ships with large fuel sources are concerned, the current utilization of waste heat from diesel engines is mainly to use the exhaust gas turbocharger to convert the exhaust gas energy into the pressure of the scavenging air to improve the power and efficiency of the diesel engine, and at the same time use the exhaust gas boiler to generate saturated water vapor of about 0.5MPa To meet the crew...
