Description

Technical Field

[0001] The utility model relates to the technical field of fuel supply, in particular to a methanol / diesel dual-fuel supply device for ships. Background Art

[0002] Water transportation occupies a place in the field of transportation due to its advantages of large transportation capacity, long transportation distance and low transportation cost.

[0003] For example, patent number CN115142968A is a ship diesel water-based methanol dual fuel supply control method and supply system, establishes a ship power real-time matching database, stores and calls the ship power real-time matching calculation results and mixed fuel combustion characteristics simulation test results; through the ship power real-time matching method, based on CFD simulation calculation of ship resistance and propeller thrust, multi-objective optimization is performed to obtain the ship main engine power that takes into account both economic indicators and emission indicators. The above documents still have deficiencies. When used, mixing methanol with water can reduce the calorific value of water-based methanol and avoid generating a large mechanical load. On the other hand, due to the vapor of water The latent heat of combustion is very large, and it can also effectively reduce NOx emissions. A ship diesel water-based methanol dual-fuel supply control method is proposed. The power matching database is used to track the ship's main engine power that takes into account both economic indicators and emission indicators. However, when the supply of methanol or diesel is stopped, the methanol that has been supplied may flow back into the methanol tank after mixing with water. When methanol is supplied, it is easy for methanol to fall into the diesel injection pipe and then flow back into the diesel tank. When the supply of methanol / diesel is stopped, it is not easy to prevent the reflux of methanol / diesel. At the same time, after methanol / diesel is supplied to the ship's main engine for combustion and discharged from the exhaust pipe, a strong odor will be generated, and the odor will diffuse slowly.
