Ship compressed air propulsion technology and device

Abstract

The invention discloses a ship compressed air propulsion technology and device. The device is mainly formed by connecting a ship engine, a compressed air box, a compressed air distribution valve, a distribution pipe, injection pipes and other parts through compressed air pipelines and can be divided into a power output system, a power distribution system and a power consumption system. The ship engine drives an air compressor to generate compressed air to push a ship to advance, and a traditional propeller or water injection propulsion mode is replaced. The compressed air injection pipes are arranged at the tail of the ship symmetrically, turning of the ship can be achieved by adjusting and controlling air injection quantity and pressure, a traditional steering engine is replaced, the turning effect is more obvious if a vector injection pipe is used, the device is simplified, and ship appendage resistance is reduced. The ship adopts the ship compressed air propulsion technology and device, the system energy efficiency is obviously higher than that of traditional propeller or water injection propulsion, and the ship compressed air propulsion technology and device further have the unique advantages that the navigational speed can reach the high navigational speed of 60 knots or above unreachable for traditional propeller or water injection propulsion, and can even reach 100 knots or above hopefully.

Description

technical field [0001] The invention belongs to the technical field of propulsion of new power devices for ships, and in particular relates to a new technology and device capable of comprehensively utilizing compressed air energy to realize high-speed and high-efficiency propulsion of ships. Background technique [0002] Most ships are propelled by propellers, and their speed basically does not exceed 30 knots; only a few ships are propelled by water jets, and their speed is difficult to exceed 60 knots. Above 60 knots has become a technical bottleneck that is difficult to overcome; another major problem is The propulsion efficiency of the propeller is difficult to reach 50%, and the efficiency of water jet propulsion is slightly higher, but it is also difficult to exceed 70%. In order to achieve high-speed and high-efficiency propulsion, the use of compressed air propulsion for ships is an ideal technical solution. Under the background of today's emphasis on energy conserva...
