The marine bubble resistance reduction device is arranged on the outer surface of a ship body and comprises a bulge, an air inlet mechanism and the water inlet flow channel, the bulge is installed on the upper portion of the front end of the bubble resistance reduction device, has a streamline appearance and protrudes downwards, and the bulge comprises a wave rider shell, an upper structure and a cavity. The waverider shell and the upper structure form a cavity, an air nozzle of an air inlet mechanism is installed on the waverider shell, the air nozzle sprays air provided by an air supply system in the ship into the water inlet flow channel for air-liquid mixing to form microbubbles, the microbubbles are sprayed out through the air-liquid nozzle, and a continuous bubble layer is formed at the bottom of the ship shell. Aiming at the current situation that the energy efficiency of the current ship is difficult to improve by the increasingly stringent emission regulations, the bubble resistance reduction device with the water inlet flow channel is arranged on the outer surface of the ship body by introducing the bubble resistance reduction technology, the problems that an existing resistance reduction device is high in energy consumption and inconvenient to install can be solved, and the bubble resistance reduction device has the advantages of being energy-saving, efficient, uniform in bubble and convenient to install.
本发明涉及一种带进水流道的船用气泡减阻装置,布置在船体外表面,包括鼓包、进气机构、进水流道,所述鼓包安装于气泡减阻装置前端上部,具有流线外形,向下方凸出,所述鼓包包括乘波外壳、上部结构和空腔,所述乘波外壳和上部结构构成空腔,乘波外壳上安装有进气机构的空气喷嘴,由空气喷嘴将船内供气系统提供的空气喷入进水流道进行气液混合,形成微气泡,并经气液喷口喷出,在船壳底部形成连续的气泡层。本发明针对当前船舶面临日益严苛的排放法规提升能效困难的现状,通过引入气泡减阻技术,在船体外表面布置带进水流道的气泡减阻装置,可解决现有减阻装置能耗偏高和安装不便的问题,具有节能高效,气泡均匀和安装方便的优点。
