Problems solved by technology

[0003] Most of the existing ships use the temperature difference between the waste heat of the exhaust gas and the seawater to generate electricity, but they need to introduce external seawater, so that the pump body needs to be used to pump the seawater, and the ship cannot be started when there is no electricity.

Abstract

The invention relates to a power generation system utilizing waste heat of a marine diesel engine. The system comprises a floating cover floating on the sea surface and connected with a waste gas outlet of the marine diesel engine through a waste gas pipeline, and a temperature difference power generation system rotationally arranged in the floating cover and generating power through the temperature difference formed by seawater and diesel engine waste gas, wherein the temperature difference power generation system is driven by wind power and / or seawater flow blown into the floating cover by waste gas of the diesel engine to rotate. The floating cover and the temperature difference power generation system are arranged on the sea surface, waste gas and seawater can be used for temperature difference power generation, seawater and air can also be used for temperature difference power generation, a drum-type temperature difference power generation device driven by the waste gas or the seawater to rotate can also drive a power generator to generate power, the power generation efficiency is higher through multiple power generation modes, the whole system can be directly installed on an existing ship for use, the structure is simple, and installation is very convenient.

Description

technical field [0001] The invention belongs to the technical field of marine energy, and in particular relates to a power generation system utilizing waste heat of a marine diesel engine. Background technique [0002] When the marine diesel engine is working, it will produce a large amount of high-temperature flue gas from the diesel engine. This part of the flue gas will carry about 30% of the diesel combustion heat and discharge it into the atmosphere, resulting in energy loss. In order to improve the energy utilization efficiency of the entire diesel engine system, it is particularly important to utilize the waste heat of its high-temperature exhaust gas. [0003] Most of the existing ships use the temperature difference between the waste heat of the exhaust gas and the seawater to generate electricity, but they need to introduce external seawater, so they need to use the pump body to pump the seawater, and the ship cannot be started when there is no electricity.
