Efficient power system for ships

Abstract

The invention discloses an efficient power system for ships and belongs to the field of mechanical devices. The efficient power system for ships comprises an oil storage tank, a generator, a ship engine and an engine waste heat device; the oil storage tank is provided with an oil inlet pipe and an oil outlet pipe; the oil outlet pipe is connected with the generator through an oil transmission pipe; a heat dissipating coil is installed at the center of the generator; an air distributor is installed right under the heat dissipating coil; the heat dissipating coil is connected with the engine waste heat device through a waste heat pipe and a backflow waste heat pipe; the engine waste heat device is connected with the ship engine through a circulating water pipe; the generator is provided with a gas outlet pipe; the gas outlet pipe is connected to the internal of the ship engine. The efficient power system for ships of the invention has simple integral structure, stable operation, efficient gas supply and long service life and is low in cost; the size of the whole machine is reduced; the efficient power system for ships is convenient for use and is easy to promote.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a high-efficiency power system of a ship. Background technique [0002] The ship's power system is the most important technical part of the ship, and its performance not only directly affects the efficiency of ship transportation, but also relates to the human living environment. Since ships generally use heavy oil or diesel oil today, the innovation of marine power systems and the replacement of new energy sources are inevitable. However, this has also caused troubles for shipowners and the shipbuilding market. At present, LNG is mainly used as the power fuel for renovation and new construction of gas-powered ships. Limited by the storage and use standards of LNG fuel, the existing technology has the following problems and shortcomings: (1) LNG The main component is liquid methane, with a boiling point of -161.5°C and a flash point of -188°C. The extremely cold ...

However, this has also caused troubles for shipowners and the shipbuilding market. At present, LNG is mainly used as the power fuel for renovation and new construction of gas-powered ships. Limited by the storage and use standards of LNG fuel, the existing technology has the following problems and shortcomings: (1) LNG The main component is liquid methane, with a boiling point of -161.5°C and a flash point of -188°C

(3) The existing technology of LNG storage tanks is basically placed on the upper deck of the ship, which requires extremely high quality, safety and technical requirements for storage tanks and auxiliary facilities

In order to prevent LNG gasification and leakage, the storage tank must use double-layer stainless steel vacuum tanks, and the auxiliary facilities such as pipelines and decompression skids are equipped with explosion-proof layers. The cost of the whole machine is too high
