The invention relates to a marine air layer resistance-reducing energy-saving device which comprises a ship body. One or more sets of air supply systems are arranged in the ship body. The output end of a single set of air supply system is connected with a ventilation main pipe, the output end of the ventilation main pipe is sequentially connected with multiple stages of pipelines, and an air cavity air conveying pipe is installed in the front of the joint of every two adjacent stages of pipelines in a penetrating mode. Pressure stabilizing cavities are fixedly formed in the ship bottom of theship body and distributed in parallel in the width direction of the ship body, a plurality of downwards-penetrating air spraying heads are arranged on the pressure stabilizing cavities side by side, and air holes are formed in the outer wall of the ship bottom. The air cavity air conveying pipes convey air into the pressure stabilizing cavities through air cavity injection pipes, and the air is output through the air spraying heads and forms an air layer on the outer wall of the ship bottom. Air is injected between the outer surface of the ship body and water to form uniform and stable gas-liquid two-phase flow, so that the navigation resistance of the ship is reduced, and the propulsion efficiency of the ship is improved. A remarkable application effect can be achieved on resistance reduction and speed increase of a high-speed boat and energy conservation and emission reduction of a large transport ship, and construction of a green and low-carbon ship transport system is effectively assisted.

    本发明涉及一种船用气层减阻节能装置,包括船体,其内设置一套或多套供气系统,单套供气系统的输出端连接通气总管,通气总管的输出端依次连接多级管路,相邻两级管路连接处的前部贯通安装气腔输气管;船体的船底固装稳压腔,稳压腔沿着船体宽度方向平行分布,稳压腔上并列开有多个向下贯穿的喷气头,船底外壁上设置有气穴;气腔输气管经气腔注入管向稳压腔内输气,气体经喷气头输出并在船底外壁上形成气层。本发明通过在船体外表面和水之间注入空气形成均匀稳定的气液两相流,从而降低船舶航行阻力,提高船舶推进效率,在高速艇的减阻提速、大型运输船舶的节能减排上均能取得显著应用效果,有效助力于绿色、低碳的船舶运输体系构建。
